technical field

The present invention relates to the technical field of electronic equipment, and in particular, to a control method of a proximity light sensor and related equipment.

Background technique

Proximity sensor is a general term for sensors that replace contact detection methods such as limit switches, and are designed to detect without touching the detection object. It detects the movement and presence of objects and converts them into electrical signals. Proximity sensors are mainly used to detect the displacement of objects, and are widely used in aviation, aerospace technology and industrial production.

At present, in terminal products, commonly used proximity sensing solutions are generally divided into ultrasonic solutions, capacitive touch screen solutions, and optical solutions. For example, on a mobile phone, the mobile phone is driven to complete the corresponding configuration by detecting the distance between the object and the screen of the mobile phone. Common applications include phone scenes. When the proximity light sensor detects that the face is close to the phone screen, the screen is turned off to reduce power consumption and prevent accidental touches on the screen; when the proximity light sensor detects that the face is far away from the phone screen, the screen is turned on, so that the user can Can continue to operate the phone screen.

Among them, in the optical solution of the proximity sensor (which may be referred to as a proximity light sensor for short), the proximity light sensor is usually formed by using an independent infrared transmitter and an infrared receiver. The infrared transmitter emits infrared light that is invisible to the human eye, and the infrared receiver is used to receive the infrared light. When there is no object approaching, the infrared light will not be reflected, and the receiver will not detect the infrared signal; when there is an object approaching and reaching a certain distance (this distance is called the detection distance), the reflected intensity of the infrared light reaches the detection threshold. The receiver detects the intensity of the reflected infrared light, or the time difference between infrared light emission and reception to determine the proximity of the object. When it is close to a certain distance, it will report the proximity status.

In the optical scheme under the full screen, the infrared transmitter and the receiving device are placed under the organic light emitting diode (Organic Light Emitting Diode, OLED) display screen, so as to realize the close-to-optical signal acquisition under the full screen. However, under a certain emission power, the infrared light emitted by the infrared emitter is prone to produce spots in the area where the infrared light illuminates the OLED display screen, thereby affecting the screen display and the use of the user.

SUMMARY OF THE INVENTION

Embodiments of the present invention provide a proximity light sensor control method and related devices, so as to improve user experience of an electronic device in a call state.

In a first aspect, an embodiment of the present invention provides a method for controlling a proximity light sensor, which is applied to an electronic device, where the electronic device includes a display screen and a proximity light sensor disposed below the display screen; the method includes: receiving a For the first call request, control the display screen to enter the bright screen state, and control the transmit power of the proximity light sensor to be the first transmit power; accept the first call request and enter the first call state; if the first call request is detected The preset condition is to control the display screen to enter the off-screen state, and control the emission power of the proximity light sensor to be the second emission power; or, if the first preset condition is not detected, and the user and the display screen have a relationship If the distance is less than the screen-off distance threshold, control the display screen to enter the screen-off state, and control the emission power of the proximity light sensor to be the second emission power; if the second preset condition is not detected, and the user and the display If the distance of the screen is greater than the bright-screen distance threshold, the display screen is controlled to enter the bright-screen state, and the transmit power of the proximity light sensor is controlled to be the first transmit power; wherein the bright-screen distance threshold is greater than the off-screen distance Threshold; the first transmit power is less than the second transmit power.

In this embodiment of the present invention, when the electronic device initially receives the first call request and before the call is connected, since the display screen of the electronic device needs to be in a bright screen state (otherwise it cannot answer the call), at this time, in order to avoid Because the power of the proximity light sensor is too high, the display screen under bright screen has the problem of flickering of bright spots, and also because it is in the bright screen state, the transmit power of the proximity light sensor can be controlled to be a lower first transmit power , which not only avoids the problem of bright spot flickering, but also ensures the monitoring accuracy of the proximity light sensor. When the electronic device is in a call state, the distance between the user and the electronic device at this time is monitored by a proximity light sensor disposed under the display screen of the electronic device. Moreover, for the screen-on and screen-off of the display screen of the electronic device in the call state, different screen-on-off processes and transmission power control of the proximity light sensor are performed for different situations. Specifically, when the electronic device does not detect a screen-off condition with a higher priority, it further determines whether the current distance between the user and the display screen is less than the screen-off distance threshold (or called the proximity distance), if it is less than, Then, by controlling the display screen to enter the off-screen state, and adjusting the transmit power of the proximity light sensor to a higher second transmit power; when the electronic device does not detect a bright screen condition with a higher priority, it is further determined by judging the user's current Whether the distance from the display screen is greater than the bright screen distance threshold (or called the distance from the bright screen), if it is greater than that, enter the bright screen state by controlling the display screen, and adjust the transmit power of the proximity light sensor to a lower first transmit power . In this way, during the call of the electronic device, the emission power of the proximity light sensor is low when the screen is bright, which avoids the occurrence of bright spots and flickering on the display screen when the screen is bright due to the high emission power of the proximity photo sensor. Defects, and since the distance between the user and the display screen that the electronic device needs to be monitored by the proximity light sensor when the screen is on is short (because the screen-off distance threshold or the proximity distance is a short distance), the proximity light sensor monitoring can be guaranteed. At the same time, because the emission power of the proximity light sensor is higher when the screen is off, and the difference in emission power between the proximity light sensor when the screen is bright and the screen is off is large, it can detect a farther distance and ensure that The large difference between the close distance and the far distance solves the problem of the electronic device repeatedly turning on and off the screen during a call due to the short distance distance and the small difference between the close distance and the far distance. It can not only help users save power consumption and prevent users from accidentally touching, but also greatly improve the user experience during a call.

In a possible implementation manner, if the first preset condition is not detected, and the distance between the user and the display screen is not less than the screen-off distance threshold, keep controlling the display screen to enter the screen-off state, and keep Controlling the transmit power of the proximity light sensor to be the second transmit power; or, if the display screen enters an off-screen state and the second preset condition is detected, the display screen is controlled to enter a bright-screen state, and the The transmit power of the proximity light sensor is the first transmit power.

In the embodiment of the present invention, since the first preset condition has a priority higher than the condition for determining whether to turn off the screen by the target distance between the user and the display screen. Therefore, if the electronic device detects the first preset condition, at this time, regardless of whether the target distance between the user and the display screen is less than the screen-off distance threshold, the electronic device needs to control the display screen to switch to the screen-off state and close the proximity light sensor. The transmit power is adjusted to a higher power. Because, at this time, it can be determined that the user needs or has a strong intention to switch to the off-screen state, or the electronic device determines that the user has a high probability that the screen is in the off-screen state under the current situation. Therefore, in this case, the electronic device may control the display screen to switch to the off-screen state and adjust the transmit power of the proximity light sensor to a higher power, so as to increase the distance detectable by the proximity light sensor. At the same time, since the second preset condition has a higher priority than the condition for determining whether to turn on the screen based on the target distance between the user and the display screen. Therefore, if the electronic device detects the second preset condition, no matter whether the target distance between the user and the display screen is greater than the bright screen distance threshold, the electronic device needs to control the display screen to switch to the bright screen state and close the light sensor The transmit power is adjusted to a lower power. Because, at this time, it can be determined that the user needs or has a strong intention to switch to the bright screen state, or the electronic device determines that the user has a high probability that the screen is in the bright screen state under the current situation. Therefore, in this case, the electronic device can control the display screen to switch to the bright screen state and adjust the transmission power of the proximity light sensor to a lower power, so as to avoid the problem of bright spot flickering under the bright screen caused by the high power of the proximity light sensor . To sum up, the embodiments of the present invention solve the problem that the electronic device repeatedly turns on and off the screen during a call due to the short distance between the distance and the distance between the close distance and the distance, so as to help the user save power consumption and prevent the user from accidentally touching the screen. And greatly improve the user experience during the call. It can be understood that the embodiment of the present invention can be applied to a call in a hands-free state or a call in a non-hands-free state, that is, the first call state may include a call in a hands-free state and/or a non-hands-free state. call below.

In a possible implementation manner, the first call state includes a non-hands-free call state; the method further includes: when the electronic device is in the second call state, turning off the function of the proximity light sensor; when the electronic device is in the second call state; When the display screen is in a bright screen state, if the first preset condition is detected, the display screen is controlled to switch to a screen-off state; when the display screen is in a screen-off state, if the first preset condition is detected. The second preset condition is to control the display screen to switch to a bright screen state.

In this embodiment of the present invention, when the electronic device performs different screen-on/off controls for the hands-free calling state and the non-hands-free calling state, and adjusts the transmit power of the proximity light sensor, for the non-hands-free calling state, it can still be used. The control method in the first aspect above is to perform comprehensive judgment in combination with the first preset condition, the second preset condition, the relationship between the target distance and the threshold value of the on/off distance distance, so as to perform related control and adjustment. However, for a call in a hands-free state, the screen can be turned on and off differently only according to whether the first preset condition or the second preset condition is received. That is to say, in this case, since the relationship between the target distance between the user and the display screen is not considered, the function of the proximity light sensor can be turned off (ie, it is not necessary to adjust its transmission power). For example, if the user turns on the hands-free function after connecting to the phone, even if the distance between the subsequent user and the display screen is less than the screen-off distance threshold, the screen will still be kept on. The screen can be switched off only when the screen is off when the phone is in the hands-free state, and the screen is off when the phone is in the off-screen state when the phone is in the hands-free state. Wait for the trigger condition to switch on the bright screen.

In a possible implementation manner, the method further includes: receiving a user's switching operation of the pass state, and entering a second call state, wherein the first call state includes a non-hands-free call state, and the second call state The state includes a hands-free calling state; if the first preset condition is detected, the display screen is controlled to enter a screen-off state, and the transmit power of the proximity light sensor is controlled to be the second transmit power; if detected For the second preset condition, the display screen is controlled to enter a bright screen state, and the transmit power of the proximity light sensor is controlled to be the first transmit power.

In this embodiment of the present invention, when the electronic device performs different screen-on/off controls for the hands-free calling state and the non-hands-free calling state, and adjusts the transmit power of the proximity light sensor, for the non-hands-free calling state, it can still be used. The control method in the first aspect above is to perform comprehensive judgment in combination with the first preset condition, the second preset condition, the relationship between the target distance and the threshold value of the on/off distance distance, so as to perform related control and adjustment. However, for calls in the hands-free state, different screen-on/off controls and adjustment of the transmit power of the proximity light sensor can be performed only according to whether the first preset condition or the second preset condition is received. That is to say, in this case, the relationship of the target distance between the user and the display screen is not considered. For example, if the user turns on the hands-free function after answering the phone, even if the target distance between the subsequent user and the display screen is less than the screen-off distance threshold, the display screen will still be kept on and the transmit power of the proximity light sensor will be controlled. At a lower first transmit power, when the user's active screen-off operation is received, or when conditions such as standing for a long time are triggered, the screen-off switch is performed and the transmit power of the proximity light sensor is controlled to a higher second transmit power; the same The same is true for calls in the hands-free state when the screen is off. When the user's active screen-on operation is received or a trigger condition such as a new message or incoming call is detected, the screen-on-screen switch is performed and the transmit power of the proximity light sensor is controlled. to a lower first transmit power. It should be noted that, in the embodiment of the invention, although the on-off of the screen is determined by not detecting the target distance through the proximity light sensor after turning on the hands-free, the above-mentioned target distance may still be required for some other functions on the electronic device. , so in this embodiment of the present invention, the emission power of the proximity light sensor can still be adjusted according to the on-off condition of the screen.

In a possible implementation manner, the first preset condition includes: the electronic device receives a screen-off operation triggered by a user; or the electronic device is in a stationary state for a preset period of time.

In the embodiment of the present invention, the first preset condition may specifically be a screen-off operation actively performed by the user, that is, a screen-off operation triggered by the user; or when the electronic device is in a stationary state for more than a certain period of time. In any of the above cases, it means that the user may not need to operate the electronic device temporarily, so the electronic device can control the display screen to switch to the off-screen state and adjust the transmit power of the proximity light sensor to a higher power to increase the The distance the proximity light sensor can detect. Help users save power consumption and prevent users from accidentally touching, and greatly improve the user experience during a call.

In a possible implementation manner, the second preset condition includes: the electronic device receives a wake-up operation triggered by the user; or the current calling application on the electronic device is switched to the background; or the electronic device has An application program other than the current call application is running in the foreground; or the electronic device receives a new message or receives a new call.

In this embodiment of the present invention, the second preset condition may specifically be a screen-on operation voluntarily performed by the user, that is, a wake-up operation triggered by the user; or the user needs to switch the corresponding call application to the background in the current call state of the electronic device. Other applications are running in the foreground; or applications other than the calling application are running in the foreground of the electronic device, for example, multiple applications (including or not including the calling application) are run in the same foreground split screen; or the electronic device A new message is received or a new call is received. In any of the above cases, it means that the user may need to operate the electronic device at this time, so the electronic device can control the display screen to switch to the bright screen state and adjust the transmit power of the proximity light sensor to a lower power to avoid the proximity light sensor. The resulting bright spot flickering problem helps users save power consumption and prevent users from accidentally touching them, and greatly improves the user experience during calls.

In a possible implementation manner, the proximity light sensor is an infrared pulse sensor; the controlling the transmit power of the proximity light sensor to be the second transmit power includes: increasing the pulse current of the infrared pulse sensor value, the transmission power of the infrared pulse sensor is adjusted to the second transmission power; or by increasing the pulse width value of the infrared pulse sensor, the transmission power of the infrared pulse sensor is adjusted to the second transmission power; Or by increasing the number of pulses of the infrared pulse sensor, the transmission power of the infrared pulse sensor is adjusted to the second transmission power.

In the embodiment of the present invention, when the proximity light sensor is an infrared pulse sensor, the electronic device can increase the current value of the pulse emitted by the infrared pulse sensor, or increase the pulse width value of the pulse emitted by the infrared pulse sensor, or increase the value of the pulse emitted by the infrared pulse sensor. One or more ways in the number of pulses to make the infrared pulse sensor increase to a larger transmit power.

In a possible implementation manner, the proximity light sensor is an infrared pulse sensor; the controlling the emission power of the proximity light sensor to be the first emission power includes: reducing the current of the pulse of the infrared pulse sensor value, the transmission power of the infrared pulse sensor is adjusted to the first transmission power; or by reducing the pulse width value of the pulse of the infrared pulse sensor, the transmission power of the infrared pulse sensor is adjusted to the first transmission power; Or by reducing the number of pulses of the infrared pulse sensor, the transmission power of the infrared pulse sensor is adjusted to the first transmission power.

In the embodiment of the present invention, when the proximity light sensor is an infrared pulse sensor, the electronic device can reduce the current value of the pulse emitted by the infrared pulse sensor, or reduce the pulse width value of the pulse emitted by the infrared pulse sensor, or reduce the pulse width emitted by the infrared pulse sensor. One or more ways in the number of pulses to reduce the infrared pulse sensor to a smaller transmit power.

In a possible implementation manner, the second transmit power is twice or more than the first transmit power.

In the embodiment of the present invention, by adjusting the difference between the transmit powers of the proximity light sensor to a range of twice or more, the distance that can be detected by the proximity light sensor can be increased, and a larger proximity distance and distance can be ensured. difference in distance. Therefore, the problem of repeatedly turning on and off the screen of the electronic device during a call due to the short distance from the distance and the small difference between the approach distance and the distance from the electronic device is solved. It can help users save power consumption and prevent users from accidentally touching, which greatly improves the user's experience during a call.

If the screen-locking condition is detected, the display screen is controlled to enter the screen-off and always-displayed AOD state, and the transmit power of the proximity light sensor is controlled to be the first transmit power;

If the second preset condition is not detected, and the distance between the user and the display screen is greater than the bright screen distance threshold, the display screen is controlled to enter the AOD state, and the transmit power of the proximity light sensor is controlled to be the first transmit power ;

In this embodiment of the present invention, the distance between the user and the electronic device at this time is monitored by a proximity light sensor disposed under the display screen of the electronic device. Moreover, when the display screen of the electronic device is in the AOD state, the switching between the AOD state and the screen-off state and the control of the transmit power of the proximity light sensor are performed for different situations. Specifically, when the electronic device is in the AOD state, when the electronic device does not detect a screen-off condition with a higher priority, it is further determined whether the current distance between the user and the display screen is less than the screen-off distance threshold (or referred to as the screen-off distance threshold). Proximity distance), if it is less than the screen, enter the off-screen state by controlling the display screen, and adjust the emission power of the proximity light sensor to a higher second emission power; when the display screen is in the off-screen state, and when the electronic device is not When an AOD condition with a higher priority is detected, it is further judged whether the distance between the user and the display screen is greater than the bright screen distance threshold (or called the distance distance). and adjusting the transmit power of the proximity light sensor to a lower first transmit power. In this way, in the AOD state of the electronic device, due to the low emission power of the proximity light sensor, the defect of bright spot flickering on the display screen in the AOD state caused by the high emission power of the proximity light sensor is avoided, and Since the distance between the user monitored by the proximity light sensor and the display screen of the electronic device in the AOD state is short (because the screen-off distance threshold or the proximity distance is a short distance), the monitoring accuracy of the proximity light sensor can be guaranteed. At the same time, due to the high transmit power of the proximity light sensor when the screen is off, and the large difference in transmit power between the AOD and the proximity light sensor when the screen is off, it can detect a farther distance and ensure a greater The difference between the close distance and the far distance solves the problem of repeated switching between the AOD and the off-screen state caused by the short distance distance and the small difference between the close distance and the far distance of the electronic device in the AOD state.

detailed description

The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

The terms "first", "second", "third" and "fourth" in the description and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order . Furthermore, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes unlisted steps or units, or optionally also includes For other steps or units inherent to these processes, methods, products or devices.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device may be components. One or more components may reside within a process and/or thread of execution, and a component may be localized on one computer and/or distributed between 2 or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon.

First, some terms in this application will be explained so as to facilitate the understanding of those skilled in the art.

(1) (Off screen) Always on display (AOD), when the screen is locked or off, only the clock and some common information are displayed through individual pixels, which enables smartphone users to press the power button less often Light up the entire screen to check whether the clock box has information such as incoming calls and text messages, which can relatively save power compared to the previous LED screen with the backlight of the entire screen turned on.

(2) Electrostatic discharge (Electronic Static Discharge, ESD) refers to the charge transfer caused by objects with different electrostatic potentials approaching or directly contacting each other.

(3) Organic Light Emitting Diode (OLED), also known as organic electric laser display, organic light emitting semiconductor. OLED belongs to a current-type organic light-emitting device, which is a phenomenon of luminescence caused by the injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, injected into the hole transport layer and the electron transport layer, respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules and finally producing visible light.

(4) Vertical cavity surface emitting lasers (VCSELs), also translated as vertical cavity surface emitting lasers, are a kind of semiconductors whose lasers are emitted perpendicular to the top surface. Edge-fired edge-fired lasers are different.

(5) Pulse width, (Pulse-Width) Pulse width is the abbreviation of pulse width. Different fields have different meanings of pulse width. The usual pulse width refers to the period during which the pulse can reach the maximum value in the field of electronics.

First, the technical problems to be solved by this application are further analyzed. In the above-mentioned optical scheme of the proximity sensor under the full screen, the low emission power pulse light source and the high sensitivity receiver are used to realize the acquisition of the proximity light signal under the full screen, and the infrared light intensity reflected by the infrared receiver is used to judge the proximity of the object. When it is close to a certain distance, it will report the proximity status. However, under a certain emission power, the infrared light emitted by the infrared emitter is prone to produce bright spots in the area where the infrared light illuminates the OLED display screen, and the apparent degree depends on the emission power of the light source.

Therefore, in order to reduce the obvious degree of spots caused by infrared light irradiating the OLED display screen, consider using a light source with a lower emission power for the infrared emitter under the full screen, that is, reducing the power of the infrared emitter in the proximity sensor, thereby reducing the infrared light illuminating the OLED. The probability of spotting in the area of the display screen to avoid affecting the screen display and user usage.

However, due to the low transmittance of the OLED display to infrared light (for example, the transmittance of infrared light and the transmittance of infrared light are both about 4%), it may result in a small amount of energy detected by the infrared receiver, that is, a small amount of signal. Eventually, the infrared light far away from the signal to noise ratio is small, and then the far distance (ie the bright screen distance threshold in this application) is short, and the difference between the close distance (ie the screen off distance threshold in the present application) and the far distance is small. As a result, the mobile phone is prone to repeatedly turning on and off the screen when answering a call at a close distance from the face. Among them, in the embodiment of the present invention, the distance of distance means that when the proximity light sensor detects that the distance between the user and the display screen is greater than the distance, it will report that the user is in a distant state, and the proximity distance means that the proximity light sensor is detecting When the distance between the user and the display screen is less than the proximity distance, the user is reported as being in proximity state; the proximity signal-to-noise ratio of infrared light is defined as the signal difference between the proximity distance and the noise floor divided by the noise fluctuation, and the distance of the infrared light away The signal-to-noise ratio is defined as the difference between the signal distance and the noise floor divided by the noise fluctuation. Among them, the noise floor is the raw data (Pdata) value in the unobstructed state of the proximity light sensor. When the signal-to-noise ratio is less than or equal to 1, the change amount of the approaching light signal of the approaching or moving away action is submerged in the noise fluctuation, and the approaching light detector (infrared receiver) cannot distinguish the approaching or moving away action, resulting in the mobile phone not being able to approach and leave according to the predetermined approach. Distance to achieve screen-off or screen-on function. The specific performance is that the user can't turn off the screen when approaching the mobile phone or the user can't brighten the screen when the user is far away from the mobile phone; when the signal-to-noise ratio is greater than 1, the change amount of the approaching light signal of the approaching or moving away action can be distinguished from the noise fluctuation, and the mobile phone can only press the predetermined approach distance. , The screen off and bright screen functions are realized far away, and the greater the signal-to-noise ratio, the higher the success rate.

This shows the shortcomings of the above solutions: the problem of flickering of bright spots on the display screen and the performance experience of bright and off-screen performance far away from the scene cannot be taken into account.

To sum up, the technical problems to be solved in this application specifically include the following aspects: how to solve the problem of far-from-signal-to-noise comparison of detection on the premise of solving the bright spot flicker in the display screen in the optical solution of the proximity sensor in the full screen Small, resulting in a short distance away and a small difference between the close distance and the far distance, causing the user to repeatedly turn on and off the screen when answering calls (including instant voice communication or non-instant voice communication, etc.) through the mobile phone.

The embodiment of the present invention takes an Android system with a layered architecture as an example to illustrate the software structure of the electronic device 100 as an example.

FIG. 1B is a block diagram of a software structure of an electronic device 100 according to an embodiment of the present invention.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, an application layer, an application framework layer, an Android runtime (Android runtime) and a system library, and a kernel layer.

The application layer can include a series of application packages.

As shown in Fig. 1B, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in FIG. 1B, the application framework layer may include window managers, content providers, view systems, telephony managers, resource managers, notification managers, and the like.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, take screenshots, etc.

Content providers are used to store and retrieve data and make these data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone book, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. View systems can be used to build applications. A display interface can consist of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide the communication function of the electronic device 100 . For example, the management of call status (including connecting, hanging up, etc.).

The resource manager provides various resources for the application, such as localization strings, icons, pictures, layout files, video files and so on.

The notification manager enables applications to display notification information in the status bar, which can be used to convey notification-type messages, and can disappear automatically after a brief pause without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also display notifications in the status bar at the top of the system in the form of graphs or scroll bar text, such as notifications of applications running in the background, and notifications on the screen in the form of dialog windows. For example, text information is prompted in the status bar, a prompt sound is issued, the electronic device vibrates, and the indicator light flashes.

Android Runtime includes core libraries and a virtual machine. Android runtime is responsible for scheduling and management of the Android system.

The core library consists of two parts: one is the function functions that the java language needs to call, and the other is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, safety and exception management, and garbage collection.

A system library can include multiple functional modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The Surface Manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, G.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display drivers, camera drivers, audio drivers, and sensor drivers.

The software system shown in FIG. 1B involves application presentation (such as gallery, file manager) using sharing capability, instant sharing module providing sharing capability, print service and print spooler providing printing capability , and the application framework layer provides printing framework, WLAN services, Bluetooth services, and the kernel and the bottom layer provide WLAN Bluetooth capabilities and basic communication protocols.

In the following, the workflow of the software and hardware of the electronic device 100 is exemplarily described in conjunction with the capturing and photographing scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into raw input events (including touch coordinates, timestamps of touch operations, etc.). Raw input events are stored at the kernel layer. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event. Take the operation as a touch operation, and the control corresponding to the touch operation is the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer. 193 Capture still images or video.

It can be understood that, FIG. 2A and FIG. 2B only exemplarily show the distribution positions of some components on the electronic device 100 and the user interface, and should not constitute a limitation to the embodiments of the present application.

The following describes the control method of the proximity light sensor provided by the embodiment of the present invention in detail with reference to the hardware structure, software structure, position distribution relationship of some components, and user interface of the electronic device shown in FIG. 1A-FIG. 2B . In the proximity light sensor control method provided by the embodiment of the present invention, the processor 110 in the electronic device 100 monitors whether a preset bright screen condition or screen off condition is detected according to the current on/off state of the display screen 194, If it is not detected, according to the target distance between the user and the display screen 194 detected by the proximity light sensor 180G, the on/off of the display screen 194 and the transmit power of the proximity light sensor 180G are controlled. Specifically, when the electronic device 100 is in the call state, the target distance between the user and the display screen 194 is detected by the proximity light sensor 180G; when the display screen 194 is in the bright screen state, if the first preset condition (for example, the display screen 194) is not detected If the target distance is smaller than the screen-on distance threshold, control the display screen 194 to enter the screen-off state, and adjust the proximity light sensor The transmission power of 180G to the second transmission power; when the display screen 194 is in the off-screen state, if the second preset condition (such as a bright screen operation with higher priority, etc.) is not detected, it is further judged whether the target distance is greater than Bright-screen distance threshold; if the target distance is greater than the bright-screen distance threshold, the display screen 194 is controlled to enter the bright-screen state, and the transmit power of the proximity light sensor is adjusted to the first transmit power; wherein the bright-screen distance threshold is greater than all the screen-off distance threshold; the second transmit power is greater than the first transmit power. In this way, during the call of the electronic device, the emission power of the proximity light sensor is low when the screen is bright, which avoids the occurrence of bright spots and flickering on the display screen when the screen is bright due to the high emission power of the proximity photo sensor. Defects, and since the distance between the user and the display screen that the electronic device needs to be monitored by the proximity light sensor when the screen is on is short (because the screen-off distance threshold or the proximity distance is a short distance), the proximity light sensor monitoring can be guaranteed. At the same time, because the emission power of the proximity light sensor is higher when the screen is off, and the difference in emission power between the proximity light sensor when the screen is bright and the screen is off is large, it can detect a farther distance and ensure that The large difference between the close distance and the far distance solves the problem of the electronic device repeatedly turning on and off the screen during a call due to the short distance distance and the small difference between the close distance and the far distance. It can not only help users save power consumption and prevent users from accidentally touching, but also greatly improve the user experience during a call.

It should be noted that, in the present application, the user can first perform personalized settings for the proximity light sensing mode function in the process of using the electronic device.

Specifically, the setting for enabling the proximity light sensing mode function can be performed for multiple application programs currently installed on the electronic device (such as call, WeChat, QQ, video, Taobao, music, etc.).

Wherein, "call" is a calling application on electronic devices such as smart phones and tablet computers, and this application does not limit the name of the application. In the present application, the electronic device 100 is in the call state refers to the state after the electronic device 100 detects the touch operation on the answer control 512 and before the touch operation on the hang-up control 516 is detected. That is, after the user answers the call and before hanging up the call. The call state may include that the terminal electronic device is in an instant call state, and may also include that the electronic device is in a non-instant call state, that is, the call application referred to in this application may include an instant call function or a non-instant call function. in,

(1) Instant calling functions, such as mobile calling applications,

Voice calls,

voice calls, etc.

(2) Non-instant calling functions, such as,

Voice messages,

voice messages, etc.

That is, in this embodiment of the present invention, the call state of the electronic device may include all application functions that the user may need to listen to the content of the voice call or voice message close to the ear, thereby causing the electronic device 100 to repeatedly turn on and off the screen.

S302: Control the display screen to be in bright screen state + proximity light sensing low-power working mode.

Specifically, when the incoming call is initially connected (ie, the answer control 512 has just been clicked), the user has a high probability of not approaching the display screen 194 of the electronic device 100. Therefore, when the electronic device 100 detects a In the initial situation after the touch operation, the display screen 194 needs to be in a bright state (otherwise the user cannot answer the incoming call). Therefore, in the embodiment of the present invention, in order to avoid the problem of bright spot flicker caused by the operation of the proximity light sensor in the bright screen state, and because the display screen 194 is in the bright screen state, the electronic device 100 needs to monitor the target distance and proximity. The relationship between the distances, that is, to monitor whether the target distance between the user and the display screen 194 is less than the screen-off distance threshold, so the proximity light sensor 180G needs to detect and may cause the electronic device 100 to control the switching of the screen state and the proximity light emission power. The distance is a relatively small distance. Therefore, in this state (that is, in the initial stage after the call is turned on), the display screen is controlled to be in a bright screen state, and the proximity light sensor 180G is controlled to work in the proximity light sensing low-power working mode, which is the same as the present application. Refers to adjust to the first transmit power to work.

Wherein, when the electronic device receives the first call request but has not been connected yet, controls the display screen to enter a bright screen state, and controls the transmit power of the proximity light sensor to be the first transmit power power. That is to say, it can be considered that in the initial stage from the time the electronic device 100 receives the first call request to the connection of the incoming call, the electronic device controls the display screen 194 to be in a bright screen state and adjusts the proximity light sensor 180G to work at the first transmit power. , and then it can be further judged by the subsequent detection conditions and the target distance, so as to decide whether to control the on/off screen and the transmit power control of the proximity light sensor. In this embodiment of the present invention, when the electronic device initially receives the first call request and the call is not connected, the display screen of the electronic device needs to be in a bright-screen state with high probability (otherwise, the call cannot be answered), therefore, At this time, in order to avoid the problem of bright spots flickering on the display screen under the bright screen due to the high power of the proximity light sensor, and also because in the bright screen state, the electronic device needs to be monitored by the proximity light sensor between the user and the display screen. The distance is short (because the screen-off distance threshold or the approaching distance is a short distance), so by controlling the transmit power of the proximity light sensor to be a lower first transmit power, the problem of bright spot flicker is avoided, and the Ensure the accuracy of proximity light sensor monitoring.

S303: Determine whether the first preset condition is detected (eg, receiving a screen-off operation, detecting that the electronic device has been standing for a long time).

Specifically, after the user answers the call, the electronic device 100 monitors and determines whether the first preset condition is detected. The first preset condition is that the priority is higher than the condition for determining whether to turn off the screen by the target distance between the user and the display screen.

The first preset condition may include one or more of the following:

(1) The electronic device 100 detects a user operation (such as a pressing operation on the button 190b) acting on the screen-off control (such as the power button 190b shown in FIG. 2A ), and in response to the operation, the electronic device 100 can further In the judging step S305, it is judged whether the distance between the user and the display screen 194 is smaller than the screen-off distance threshold, wherein the button 190b can be used to monitor the user operation that triggers the screen-on or screen-off. For example, please refer to FIG. 5B . FIG. 5B is a schematic diagram of some users pressing the power button 190b to turn off the screen during a call according to an embodiment of the present invention. The user interface 53 is a call interface after the user normally connects the phone. When the electronic device 100 detects the user's pressing operation on the power button 190b, the electronic device 100 controls the display screen 194 to enter the off-screen state, that is, the user interface 54, and at the same time. It is necessary to control and adjust the transmit power of the proximity light sensor 180G to a second, higher transmit power. When the display screen of the electronic device is in the bright screen state, after the user presses the button 190b, the display screen will be automatically turned off and the transmit power of the proximity light sensor will be increased. The key 190b may be a mechanical key or a touch key.

(2) The electronic device 100 detects that the electronic device itself has been left standing for a long time. For example, the electronic device 100 can determine the movement posture of the electronic device 100 through the gyro sensor 180B, and detect the acceleration of the electronic device 100 in various directions (generally three axes) through the acceleration sensor 180E. If the movement posture and the acceleration in each direction are both If there is no change, and it exceeds a certain period of time, it can be determined that the electronic device 100 has been standing for a long time. At this time, it means that the user may not need to operate the electronic device 100 temporarily, because the display screen 194 of the electronic device 100 can be controlled to automatically turn black when the display screen 194 of the electronic device 100 is in the bright screen state, but the electronic device 100 detects that it has been standing for a long time. And increase the transmit power of the proximity light sensor 180G.

If any one or more of the above-mentioned first preset conditions are detected, step S306 is executed: the display screen is controlled to be in an off-screen state, and the proximity light sensing high-power working mode is controlled.

Specifically, since the first preset condition has a higher priority than the condition for determining whether to turn off the screen through the target distance between the user and the display screen 194 . Therefore, if the electronic device 100 detects the first preset condition, then regardless of whether the target distance between the user and the display screen 194 is smaller than the screen-off distance threshold, the electronic device 100 needs to control the display screen 194 to switch to the screen-off state and Adjust the transmit power of the proximity light sensor 180G to a higher power. Because, at this time, it can be determined that the user needs or has a strong intention to switch to the off-screen state, or the electronic device 100 determines that the user has a high probability that the screen is in the off-screen state under the current situation. Therefore, in this case, the electronic device 100 may control the display screen 194 to switch to the off-screen state and adjust the transmit power of the proximity light sensor 180G to a higher power, so as to increase the distance detectable by the proximity light sensor 180G, and further prevent the User touches by mistake.

S304: If any one or more of the above-mentioned first preset conditions are not detected, determine whether the distance between the user and the display screen is smaller than the screen-off distance threshold.

Specifically, when any one or more of the above-mentioned first preset conditions are not detected, it indicates that it is currently impossible to judge whether the screen needs to be turned off through the first preset conditions. Therefore, the electronic device 100 further determines whether the target distance between the user and the display screen 194 is smaller than the screen-off distance threshold through the proximity light sensor 180G disposed under the display screen 194 . The screen-off distance threshold means that when the user reaches the screen-off distance threshold or is smaller than the screen-off distance threshold, the user has a high probability of approaching the display screen 194 of the electronic device 100 through the ear to pass the speaker 170A (in FIG. 2A ). shown) to answer the call. Therefore, the screen-off distance threshold refers to an average or common distance at which a user listens to a voice call or voice message through the speaker 170A.

S305: Control the display screen to be off-screen state + proximity light sensing high-power working mode.

Specifically, if the electronic device 100 does not detect the first preset condition and detects through the proximity light sensor 180G that the target distance between the user and the display screen 194 is smaller than the screen-off distance threshold, the electronic device 100 may control the processor 110 The display screen 194 is switched to the off-screen state, and the proximity light sensor 180G is controlled to work at a higher second transmit power, that is, in the proximity light sensing high-power working mode.

S306: Determine whether a second preset condition is detected (eg, receiving a screen-on operation, detecting a new message or incoming call, and exiting the call application to the background).

Specifically, after the user answers the phone, and the display screen 194 of the electronic device 100 is in an off-screen state (for example, the screen is off due to the detection of the first preset condition described above, or the first preset condition is not detected) condition but the detected target distance between the user and the display screen 194 is less than the screen-off caused by the screen-off distance threshold), the electronic device 100 monitors whether the second preset condition is detected. The second preset condition is that the priority is higher than the condition of determining whether to turn on the screen by the target distance between the user and the display screen.

The second preset condition may include one or more of the following for changing from off-screen to bright-screen during a call:

(1) The user clicks to trigger the screen to wake up the bright screen; the electronic device 100 detects a key or control acting on the bright screen, which may include the power button 190b shown in the above-mentioned FIG. 2A , the recording control in the call function area 514, the waiting control, Add call controls, video calls, mute controls, contact controls, etc., or the dial pad 515, hands-free controls 517, etc. at the bottom of the user interface 52 shown in FIG. 5A. In response to any of the above operations that trigger the wake-up bright screen button or control, the electronic device 100 can control the display screen 194 to enter the bright screen state, and at the same time, it needs to control to adjust the transmit power of the proximity light sensor 180G to a lower first transmit power. . When the display screen of the electronic device is in the off-screen state, after the user performs some operations such as waking up, the display screen will automatically turn on the screen and reduce the transmission power of the proximity light sensor. The key 190b may be a mechanical key or a touch key. It should be noted that, in this embodiment, the first call state includes a hands-free call state and a free hands-free call state.

(2) Switch the background bright screen; assuming that the current user is running other applications, such as WeChat, in the foreground of the electronic device 100, that is, chatting through the WeChat application, that is, running WeChat in the foreground, and exiting the calling application to the background.

For example, please refer to FIG. 5C , which is a schematic diagram of a user interface in which some users switch a call application to the background during a call according to an embodiment of the present invention. The user interface 55 is the call interface between the user and the caller Mary. When the electronic device is currently in an off-screen state (not shown in FIG. 5C ), if the electronic device 100 detects the operation of switching to the background for the call application (such as an upward swipe operation from the bottom), or an operation of bringing other applications into the foreground (such as an operation of sliding other applications to the foreground) is detected, and in response to the above operation, the user interface exemplarily shown in FIG. 5C can be displayed 56. For example, the switched user interface 56 includes the chat interface 562 of the WeChat application, and the call application switched to the background displayed as a shortcut icon 561 at the position of the navigation bar, and the user can return to the call interface 55 by clicking the shortcut icon 561. That is, when the electronic device 100 detects that the call application is switched to the background in the second preset condition, the display screen 194 is controlled to be in the bright screen state + the proximity light sensing low-power working mode.

(3) An application program other than the current call application is running in the foreground to brighten the screen; it is assumed that the electronic device runs not only the calling application in the foreground, but multiple applications running in the foreground in a split-screen manner.

For example, please refer to FIG. 5D. FIG. 5D is a schematic diagram of a user interface in which some users run a call application together with other applications in the foreground during a call according to an embodiment of the present invention. The user interface 57 is the call interface between the user and the caller Mary. When the electronic device is currently in an off-screen state (not shown in FIG. 5D ), if the electronic device 100 detects that the call application and WeChat When the application enters the foreground, in response to the above split screen operation, the user interface 58 exemplarily shown in FIG. 5D may be displayed, and the user interface is divided into split screen 581 and split screen 582 in the user interface 58 . That is, at this time, although the calling application is not switched to the background, there are other applications running in the foreground. Therefore, in order to ensure that other applications other than the calling application can be used normally, the above situation is set to belong to one of the second preset conditions. That is, at this time, the electronic device 100 detects the condition of running applications other than the calling application in the foreground among the second preset conditions, and controls the display screen to be in the bright screen state + the proximity light sensing low-power working mode.

(4) When a new message or a new phone is received, the screen is on. The electronic device 100 detects a new incoming call or a new message through the mobile communication module 150 or the wireless communication module 160 . In response to a new incoming call or a new message detected by the above-mentioned mobile communication module 150 or wireless communication module 160, the electronic device 100 may control the bright screen.

For example, please refer to FIG. 5E. FIG. 5E is a schematic diagram of a user interface in which some users receive a new incoming call during a call according to an embodiment of the present invention. The user interface 59 is the current call between the user and the caller Mary. At this time, the electronic device 100 receives the new call from the first call requester David through the mobile communication module 150, and responds to the new call detected by the mobile communication module 150. , the user interface 510 exemplarily shown in FIG. 5E may be displayed. The user can end Mary's call and answer David's call by clicking end and answer control 5101, or directly reject David's call by rejecting control 5102, or click hold and answer control 5103 to hold the call with Mary and answer David's call. Wei's phone. That is, when the electronic device detects a new incoming call in the second preset condition at this time, it controls the display screen to be in a bright screen state + a low-power working mode of proximity light sensing.

It can be understood that the call state of the present application may include instant call state and non-instant call, and the corresponding call application may include a mobile call application, and may also include a network call application and the like. As shown in FIG. 6A-FIG. 6C, they are schematic interface diagrams of voice calls and voice messages in some WeChat applications provided by embodiments of the present invention.

As shown in FIG. 6A , the user interface 61 may include a voice call information bar 611 (such as the name of the voice originator), a reject control 612 and an answer control 613. When the user wants to answer the voice call, he can use the Click the answer control 613 , when the user wants to reject the incoming call, he can do so by clicking the reject control 612 . When the electronic device 100 detects a touch operation (eg, a click operation on the icon 613 ) acting on the answering control 613 through the touch sensor 180K, in response to the operation, the user interface 62 exemplarily shown in FIG. 6A may be displayed. The user interface 62 may include a voice duration bar 614 (for displaying the duration of a call after connecting a voice call) and controls for common call functions such as: mute control 615 , hang up control 616 , and hands-free control 517 . For the related control of the screen on and off and the control of the transmit power of the proximity light sensor, reference may be made to the related description of the mobile call in FIG. 5A in the above-mentioned embodiment, which will not be repeated here.

As shown in FIG. 6B , for the user interface 63 (same as the above-mentioned user interface 62 , which will not be repeated here), when the electronic device 100 detects a touch operation on the zoom-out control 618 through the touch sensor 180K (such as the one on the icon 618 ) Click operation), in response to this operation, the user interface 64 exemplarily shown in FIG. 6A may be displayed. The user interface 64 may include a chat interface 620 of the switched WeChat application, and a call application switched to the background displayed as a shortcut icon 619 in the area of the chat interface 620, and the user can return to the voice call interface 63 by clicking on the icon 619. That is, when the electronic device 100 detects that the call application is switched to the background in the second preset condition, the display screen 194 is controlled to be in the bright screen state + the proximity light sensing low-power working mode. For details, reference may also be made to the relevant description of the mobile call in FIG. 5C in the foregoing embodiment, which will not be repeated here.

As shown in FIG. 6C , when the electronic device 100 receives a new voice message through the mobile communication module 150 or the wireless communication module 160, in response to the operation, the user interface 65 exemplarily shown in FIG. 6C may be displayed. The user interface 65 contains voice messages 651 available for listening. When the electronic device 100 detects a touch operation (such as a click operation on the icon 651) acting on the voice message 651 through the touch sensor 180K, in response to the operation, the user interface 66 exemplarily shown in FIG. 6C may be displayed. At this time, the user can listen to the voice message 651 in an externally or non-externally-played manner. In this process, you can refer to the above judgment under bright screen to determine whether the first preset condition is detected. If not, it is further judged whether the distance between the user and the display screen is less than the screen-off distance threshold. The screen enters the off-screen state and the proximity light sensor 180G is adjusted to a higher second transmit power. For details, reference may also be made to the related descriptions of the mobile calls in FIGS. 5A to 5E in the foregoing embodiments, which will not be repeated here.

If any one or more of the above-mentioned second preset conditions are detected, step S303 is executed: the display screen is controlled to be in a bright screen state, and the proximity light sensing low-power working mode is controlled.

Specifically, since the second preset condition has a higher priority than the condition for determining whether to turn on the screen through the target distance between the user and the display screen 194 . Therefore, if the electronic device 100 detects the second preset condition, at this time, regardless of whether the target distance between the user and the display screen 194 is greater than the light-off distance threshold, the electronic device 100 needs to control the display screen 194 to switch to the bright screen state and Adjust the transmit power of the proximity light sensor 180G to a lower power. Because, at this time, it can be determined that the user needs or has a strong intention to switch to the bright screen state, or the electronic device 100 determines that the user has a high probability that the screen is in the bright screen state under the current situation. Therefore, in this case, the electronic device 100 can control the display screen 194 to switch to the bright screen state and adjust the transmit power of the proximity light sensor 180G to a lower power, so as to avoid the problem of bright spot flicker caused by the higher power of the proximity light sensor 180G , to improve the user experience.

S307: Determine whether the distance between the user and the display screen is greater than the bright screen distance threshold.

Specifically, when any one or more of the above-mentioned second preset conditions are not detected, it indicates that it is currently impossible to judge whether the screen needs to be brightened through the second preset conditions. Therefore, the electronic device 100 further determines whether the target distance between the user and the display screen 194 is greater than the bright screen distance threshold through the proximity light sensor 180G disposed under the display screen 194 . The bright screen distance threshold means that when the user reaches the bright screen distance threshold or is greater than the bright screen distance threshold, the user has a high probability to stare at the display screen 194 of the electronic device 100 to pass the speaker 170A ( FIG. 2A ). shown in ) to answer the call. Therefore, the screen-off distance threshold refers to a common distance for a user to listen to a voice call or voice message through the speaker 170A.

If it is determined that the distance between the user and the display screen is greater than the bright-screen distance, step S302 is performed. For details, please refer to the above description of step S302.

If it is determined that the distance between the user and the display screen is not greater than the bright-screen distance, step S308 may be further performed. For details, please refer to the description of step S308.

S308: Determine whether the call ends.

Specifically, the electronic device monitors whether the call process ends. For example, when the user finishes the call, the user clicks the hang-up control, and the electronic device 100 detects an operation on the hang-up control, etc.; or the other party hangs up first, and the call ends.

Optionally, if the call has not ended, the process may continue to return to the judgment in step S307.

S309: If yes, end the call.

Specifically, after the call is over, for the call application, it is temporarily unnecessary for the user to answer the call by being close to the ear. Therefore, the proximity light sensing mode function for the calling application can end.

Hereinafter, the electronic device 100 is taken as a smartphone, and the control method of the proximity light sensor in the present application will be further described in combination with the actual application scenario. Please refer to FIG. 7A-FIG. 7B. FIG. 7A-FIG. 7B are schematic diagrams of some users during a call according to an embodiment of the present invention. E.g

1. As shown in Figure 7A, after the user receives the first call request and connects the phone, the user has not yet put his ear close to the speaker on the mobile phone, the mobile phone is in a bright screen state, and the proximity light sensor is controlled. Operates with a lower first transmit power.

2. When the user puts the mobile phone close to the ear (at this time, the target distance is less than the screen-off distance threshold), and before this process, the mobile phone does not detect other bright-screen conditions (ie, the first preset condition), then the mobile phone controls the mobile phone display. The screen enters the off-screen state, and the proximity light sensor is adjusted to work with a higher second transmit power.

3. As shown in Figure 7B, when the user sits down to answer the call during the call, if the mobile phone still does not detect the bright screen condition (ie the first preset condition) during this process, the mobile phone still keeps the screen off state , and the proximity light sensor operates with a higher second transmit power.

4. When the user puts the mobile phone on the table and continues to answer the call, (at this time, the target distance is greater than the bright screen distance threshold), and before this process, if the mobile phone does not detect other screen-off conditions (ie the second preset condition) , so the mobile phone controls the display screen to enter the bright screen state, and adjusts the proximity light sensor to work with a lower first transmit power.

5. Since the user leaves the mobile phone on the desktop for a long time, the mobile phone detects that the long-term standing condition in the first preset condition is currently satisfied, so the mobile phone controls the display screen to enter the off-screen state, and adjusts the proximity light sensor to a higher value. of the second transmit power to work.

6. After that, when the user actively operates the mobile phone interface (such as a wake-up operation), the mobile phone is triggered to detect the bright screen operation in the second preset condition, so the mobile phone controls the display screen to enter the bright screen state, and adjusts the proximity light sensor to a lower value. the first transmit power to work.

The method flow corresponding to FIG. 3 above can be applied to calls in a hands-free state or a call in a non-hands-free state, that is, in the method embodiment corresponding to FIG. The above-mentioned corresponding control and adjustment are performed on a call, and the above-mentioned corresponding control and adjustment can also be performed on a non-hands-free call. It can be understood that the first call state may include a hands-free call state and/or a non-hands-free call state.

In a possible implementation manner, the present application also provides another method for controlling a proximity light sensor, as shown in FIG. 8 . FIG. 8 is a schematic flowchart of another method for controlling a proximity light sensor provided by an embodiment of the present invention. The method includes: Steps S301 to S309, and steps S401 to S406, wherein, for the processing flow of the electronic device in the non-hands-free state, please refer to the relevant implementation manner of the method flow in FIG. 3, which will not be repeated here. For the processing flow of the electronic device in the hands-free state, please refer to steps S401 to S406 in FIG. 8 . The first call state includes a non-hands-free call state; the method includes:

S401: When the electronic device is in the second call state, control the display screen to be in the bright screen state and the proximity light sensing low-power working mode.

S402: When the display screen is in a bright screen state, determine whether the first preset condition is detected.

S403: If the first preset condition is detected, control the display screen to enter a screen-off state and a proximity light sensing high-power working mode.

If the second preset condition is not detected, the above-mentioned step S401 is performed.

S404: When the display screen is in an off-screen state, determine whether the second preset condition is detected.

If the second preset condition is detected, the above step S401 is executed.

If the second preset condition is not detected, step S405 may be further performed.

S405: Determine whether the call ends.

If the call is not over, the state in step S403 can be continued.

S406: If yes, end the call.

Specifically, receiving the user's switching operation of the pass state, enters a second call state, wherein the first call state includes a non-hands-free call state, and the second call state includes a hands-free call state; when the display screen When the screen is on, if the first preset condition is detected, control the display screen to enter the screen-off state, and control the emission power of the proximity light sensor to be the second emission power; when the display When the screen is in an off-screen state, if the second preset condition is detected, the display screen is controlled to enter a bright-screen state, and the transmit power of the proximity light sensor is controlled to be the first transmit power. It should be noted that, for the specific process of the proximity optical sensor method described in the embodiments of the present invention, reference may be made to the relevant descriptions in the embodiments of the present invention described in FIG. 1A to FIG. 7B , and details are not repeated here.

Optionally, if the target distance between the user and the display screen is not involved in other functions, the function of the proximity light sensor can also be turned off (that is, it is not necessary to adjust its transmit power).

For example, please refer to FIG. 5A. FIG. 5A is a schematic diagram of some users enabling a hands-free function during a call according to an embodiment of the present invention. After the user connects the phone, as shown in the user interface 52, which includes the hands-free control 517, if the electronic device 100 detects a touch operation (such as a click operation on the icon 517) acting on the control 517 through the touch sensor 180K ), in response to this operation, the electronic device turns on the hands-free function (the control 517 is switched from the previous grayscale transition state to the lighted state). Then even if the distance between the subsequent user and the display screen is less than the screen-off distance threshold, the screen will still be kept on, and the screen-off switch will only be performed when the user's active screen-off operation is received, or when conditions such as standing for a long time are triggered. ; Similarly, the same is true for calls in the hands-free state when the screen is off. When the user's active screen-on operation is received or a trigger condition such as a new message or incoming call is detected, the screen-on-screen switch is performed. Optionally, because the embodiment of the present invention does not use the detection target distance to determine the way to turn on and off the display screen for calls in the hands-free state, but only switches the display screen on and off according to the second preset condition or the second preset condition. off, so the electronic device can control the function of the proximity light sensor 194 to be turned off.

FIG. 9A shows a flow of another proximity light sensor control method provided by an embodiment of the present invention. The method is applied to any of the above electronic devices. The method flow mainly describes the method steps on the side of the electronic device. The method may include :

S901: If a screen lock condition is detected, the electronic device is in a screen lock state.

Specifically, the screen-locking condition may specifically include a screen-locking operation that is actively triggered by a user, or an automatic screen-locking operation that is triggered after the electronic device has been stationary for a long time. When the electronic device is in a locked screen state, detecting the target distance between the user and the display screen through the proximity light sensor;

S902: Control the display to AOD state + proximity light sensing low-power working mode.

S903: Determine whether the first preset condition is detected.

S904: If the first preset condition is not detected, determine whether the distance between the user and the display screen is less than the screen-off distance threshold.

S905: If it is less than, control the display screen to be off-screen state + proximity light sensor high-power working mode.

Please refer to FIG. 9B . FIG. 9B is a schematic diagram of a user interface for switching between an AOD state and an off-screen state according to an embodiment of the present invention. The left side of FIG. 9B is the user interface in the AOD state, which is used to display some simple time and date information, and the right side is the screen-off interface.

It should be noted that, for the process of the proximity light sensor control method described in the embodiment of the present invention, reference may be made to the description of the relevant steps in the method embodiment shown in FIG. 4 or FIG. 8 , and details are not repeated here.

In this embodiment of the present invention, specifically how to adjust the transmit power of the proximity light sensor, that is, adjusting the transmit power of the proximity light sensor to the second transmit power, or to the first transmit power, may include the following three ways:

Method 1: Adjust the pulse frequency of the infrared transmitter in the proximity light sensor, (from single pulse→multiple pulse)/(from multiple pulse→single pulse)

Assuming that the proximity sensor is an infrared pulse sensor, when the processor 110 in the electronic device 100 detects that the display screen 194 is in an off-screen state, the processor 110 controls to increase the pulse of the infrared transmitter 180G-a in the proximity light sensor 180G The number is also the pulse frequency, so as to control the power of the infrared transmitter to detect whether the user is approaching the display screen 194 with a large power in the off-screen state, and receive the infrared signal reflected by the user through the infrared receiver 180G-b, so that according to the signal The intensity or the time difference between the transmitted signal and the received signal is used to calculate the user's current target distance from the display screen 194 . And further according to the relationship between the distance and the bright screen distance threshold (distance distance), it is determined whether to control the display screen 194 to light up. In the off-screen state, the near-light infrared emission power can be increased by increasing the number of transmitted pulses (such as 5mA, 64us, 5pulses), so that the signal-to-noise ratio of the far distance can be improved, and it can be ensured that the mobile phone will only brighten the screen when the distance is greater than or equal to the distance. When the mobile phone is close to the face, it is easy to repeatedly turn on and off the screen when answering a call. Please refer to FIG. 10A . FIG. 10A is a schematic diagram of a timing waveform of a near-optical multi-pulse working mode in an off-screen state according to an embodiment of the present invention. It can be understood that in this application, adjusting the transmit power to the second transmit power corresponds to the right side of FIG. 10A , and adjusting the transmit power to the first transmit power corresponds to the left side of FIG. 10A .

In the embodiment of the present invention, considering the factors of the proximity optical sensor and the production line calibration mode, adopting the above method of adjusting the number of pulses is conducive to matching the production line calibration threshold. Because the production line calibration threshold can not be changed when the number of pulses is adjusted in the proximity of the light sensor, while the second and third methods require the production line calibration threshold to change dynamically. Therefore, the above-mentioned method of adopting the single-pulse switching mode and the multi-pulse switching mode does not need to change the calibration parameters of the production line, which is beneficial to the production of related products.

The core of the embodiment of the present invention is that in the mobile phone call scenario, the proximity light working mode with different emitted optical powers is adopted for brightening and extinguishing the screen: when the screen is brightened, the low-power working mode is adopted to ensure that the screen spot flicker is not obvious and the signal-to-noise ratio of the proximity distance reaches the standard (such as When the screen is off, a high-power working mode (such as multi-pulse) is used to ensure that the signal-to-noise ratio at a far distance reaches the standard. The emission energy when the screen is off can be twice or more than that when the screen is on.

Method 2: Adjust the current of the infrared transmitter in the proximity light sensor, (from low current→high current)/(from high current→low current)

In the off-screen state, the near-light infrared emission power (such as 15mA, 64us, 1pulse) can also be increased by increasing the emission pulse current, so that the signal-to-noise ratio of the far-distance distance can be improved. When the mobile phone is close to the face, it is easy to repeatedly turn on and off the screen when answering a call. Please refer to FIG. 10B . FIG. 10B is a schematic diagram of a timing waveform of a near-light high current working mode in an off-screen state according to an embodiment of the present invention. It can be understood that in this application, adjusting the transmit power to the second transmit power corresponds to the right side of FIG. 10B , and adjusting the transmit power to the first transmit power corresponds to the left side of FIG. 10B .

The core of the embodiment of the present invention is that in the mobile phone call scenario, the proximity light working mode with different emitted optical powers is adopted for brightening and extinguishing the screen: when the screen is brightened, the low-power working mode is adopted to ensure that the screen spot flicker is not obvious and the signal-to-noise ratio of the proximity distance reaches the standard (such as When the screen is off, the high-power working mode (such as high current) is used to ensure that the signal-to-noise ratio at the far distance reaches the standard. The emission energy when the screen is off can be twice or more than that when the screen is on.

Method 3: Adjust the pulse width of the infrared transmitter in the proximity light sensor, (from short pulse width→long pulse width)/(from long pulse width→short pulse width)

In the off-screen state, you can also increase the infrared emission power of the near-light by increasing the pulse width of the emission pulse (such as 5mA, 192us, 1pulse), so that the signal-to-noise ratio of the far distance can be improved, and it can be ensured that the mobile phone will be bright when the distance is greater than or equal to. Solve the problem that the screen is easy to turn on and off repeatedly when the phone is close to the face to answer the call. Referring to FIG. 10C , FIG. 10C is a schematic diagram of some users enabling a hands-free function during a call according to an embodiment of the present invention. FIG. 10C is a schematic diagram of a timing waveform of a working mode with near-optical length and pulse width in an off-screen state according to an embodiment of the present invention. It can be understood that in this application, adjusting the transmit power to the second transmit power corresponds to the right side of FIG. 10C , and adjusting the transmit power to the first transmit power corresponds to the left side of FIG. 10C .

The core of the embodiment of the present invention is that in the mobile phone call scenario, the proximity light working mode with different emitted optical powers is adopted for brightening and extinguishing the screen: when the screen is brightened, the low-power working mode is adopted to ensure that the screen spot flicker is not obvious and the signal-to-noise ratio of the proximity distance reaches the standard (such as When the screen is off, the high-power working mode (such as long pulse width) is adopted to ensure that the signal-to-noise ratio at the far distance reaches the standard. The emission energy when the screen is off can be twice or more than that when the screen is on.

The above three implementations can be based on the hardware configuration of the electronic equipment in the prior art, and rely on the software scheme to distinguish the scene to adjust the near-light infrared emission power (single pulse/multi-pulse switching, low current/high current switching, short pulse width/long pulse). Wide switching), which can not only ensure that the display spot flicker is not obvious when the screen is bright, but also can improve the performance experience far away from the scene. Compared with the prior art, the embodiment of the present invention can improve the far-away signal-to-noise ratio, so that the far-away distance increases, the approach-to-far distance difference increases, and the near-light performance experience is improved.

Further, the embodiments of the present invention can also be applied to the following scenarios: a screen-off and always-on display scenario, turning off the AOD when approaching is detected, reducing the power consumption of the proximity light sensor and preventing accidental touches; a pocket mode scenario, identifying whether the mobile phone is in a pocket Block, increase the prompt tone or prevent the password to be unlocked by mistake, answer a call by mistake, and make an emergency call by mistake; in smart backlight scenes, games, watching videos by hand, etc., the proximity light sensor is used to judge whether the current ambient light is blocked, and when it is blocked If the external environment is not really darkened, the brightness is not adjusted according to the ambient light, which will not be listed here.
