有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之一個較佳實施例的詳細說明中，將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.
參閱圖2，本發明電子系統100之較佳實施例包含一觸控裝置2及一電子裝置3。Referring to FIG. 2, a preferred embodiment of the electronic system 100 of the present invention includes a touch device 2 and an electronic device 3.
觸控裝置2包括一觸控感測器21及一控制電路22。觸控感測器21(如觸控板)感測觸碰並據此產生一感測信號S1。控制電路22具有一位置偵測器221及一第一傳輸介面222。位置偵測器221電連接觸控感測器21以接收感測信號S1，並根據感測信號S1得到與觸碰相關的一位置資訊S2。第一傳輸介面222電連接位置偵測器221以接收位置資訊S2，並將位置資訊S2傳送出去。The touch device 2 includes a touch sensor 21 and a control circuit 22 . The touch sensor 21 (such as a touch panel) senses the touch and generates a sensing signal S1 accordingly. The control circuit 22 has a position detector 221 and a first transmission interface 222. The position detector 221 is electrically connected to the touch sensor 21 to receive the sensing signal S1, and obtains a position information S2 related to the touch according to the sensing signal S1. The first transmission interface 222 is electrically connected to the position detector 221 to receive the position information S2 and transmit the position information S2.
電子裝置3與觸控裝置2一起使用，且包括一第二傳輸介面31及一中央處理單元32。中央處理單元32透過第二傳輸介面31接收位置資訊S2，並根據位置資訊S2得到一控制信號S3，並根據控制信號S3進行相對應的控制。The electronic device 3 is used with the touch device 2 and includes a second transmission interface 31 and a central processing unit 32. The central processing unit 32 receives the location information S2 through the second transmission interface 31, and obtains a control signal S3 according to the location information S2, and performs corresponding control according to the control signal S3.
在本實施例中，第一傳輸介面222及第二傳輸介面31能以無線方式進行通訊，例如符合紅外線或射頻(包括藍芽)標準，也能以有線方式進行通訊，例如符合RS-232C、PS/2、ADB或USB標準。In this embodiment, the first transmission interface 222 and the second transmission interface 31 can communicate wirelessly, for example, in compliance with infrared or radio frequency (including Bluetooth) standards, and can also communicate in a wired manner, for example, conforming to RS-232C, PS/2, ADB or USB standard.
在本實施例中，電子裝置3為一液晶電視，因此電子裝置3還包括一液晶面板33。舉例來說，當使用者欲切換液晶電視所播放的頻道時，藉由操作觸控感測器21可使中央處理單元32得到指示切換頻道的控制信號S3，並據此切換頻道，這樣可讓使用者的操作更為方便。In this embodiment, the electronic device 3 is a liquid crystal television, and thus the electronic device 3 further includes a liquid crystal panel 33.

The user's operation is more convenient.
值得注意的是，電子裝置3常常用來編解碼影音資訊或者進行複雜的處理，因此需要較高規格及多元化功能的中央處理單元32。如此一來，觸控裝置2將位置資訊S2直接交由較高規格的電子裝置3的中央處理單元32進行運算以得到控制信號S3，不僅可以提高運算速度及精確度，且觸控裝置2不需要控制處理器(圖未示)，還能降低成本。因此本實施例電子系統100確實能達成本發明之目的。It should be noted that the electronic device 3 is often used to encode and decode video information or perform complicated processing, and thus requires a central processing unit 32 of a higher specification and a plurality of functions. In this way, the touch device 2 directly passes the position information S2 to the central processing unit 32 of the higher-standard electronic device 3 to obtain the control signal S3, which not only improves the calculation speed and accuracy, but also does not control the touch device 2 The need to control the processor (not shown) can also reduce costs. Therefore, the electronic system 100 of the present embodiment can achieve the object of the present invention.
