Fig. 1 schematically shows the structure of the display panel 100 according to one embodiment of the invention.This display panel 100 can comprise: stacked cover plate 10, first substrate 11, second substrate 12, the Presentation Function lamination 14 between first substrate 11 and second substrate 12 and the wall between first substrate 11 and cover plate 10 13.In one example, cover plate 10 and second substrate 12 lay respectively at the both sides of described first substrate 11 and described cover plate 10 is positioned at the light exit side of described display panel 100.The lighttight frame region 142 that described Presentation Function lamination 14 has the image display area 141 for showing image and arranges around described image display area 14 at Presentation Function laminated edge place.
In one example, described first substrate 11 forms the first bending smooth deflector surface 111 in edge, described first smooth deflector surface 111 is positioned at the side towards wall 13 of described first substrate 11 and covers the marginal portion of the image display area 141 of Presentation Function lamination 14, as shown in Figure 1.The light 15 that described first smooth deflector surface 111 is configured to the marginal portion of the image display area 141 making to come from Presentation Function lamination 14 deflects towards the edge direction of cover plate 10, and described cover plate 10 forms the second bending smooth deflector surface 102 in edge, described second smooth deflector surface 102 is positioned at the side towards wall 13 of described cover plate 10 and covers marginal portion and the described frame region 142 of the image display area 141 of Presentation Function lamination 14.Described second smooth deflector surface 102 is configured to make the light that deflects through described first smooth deflector surface 111 to deflect towards the direction at the edge away from cover plate 10.For realizing the first smooth deflector surface 111 and the second smooth deflector surface 102 to the deflection of light, the refractive index of described wall 13 is configured to the refractive index being different from described first substrate 11 and cover plate 10.
In an embodiment according to the present invention, a light deflector surface is set respectively in the edge of substrate 11 and cover plate 10, i.e. the first smooth deflector surface 111 and the second smooth deflector surface 102.The light that these two light deflector surfaces can make image display area 141 edge of the Presentation Function lamination 14 on display panel 100 penetrate deflects towards the edge of cover plate 10.Like this, when beholder watches the display image of display panel from the light emission side (being upper side in the example of fig. 1) of display panel 100, also there is light to penetrate in the position corresponding to frame region 142 (as above frame region 142) of cover plate 10, thus display panel 10 can be made to obtain the display effect (if the part edge region of cover plate 10 has light to penetrate) of Rimless (if all fringe regions of cover plate 10 have light to penetrate) or the frame that narrows.
In one example, the light that described first smooth deflector surface 111 and the second smooth deflector surface 102 can be configured to make to deflect through the second smooth deflector surface 102 covers the described frame region 142 of described Presentation Function lamination 14 at least in part from the region of cover plate 10 outgoing.This when display panel shows, can at least reduce the frame even eliminating display panel 10.Particularly, when the light deflected through the second smooth deflector surface 102 from the area part of cover plate 10 outgoing cover the described frame region 142 of described Presentation Function lamination 14 time, the frame of display panel 10 can be made to narrow.And the light that described first smooth deflector surface 111 and the second smooth deflector surface 102 also can be configured to make to deflect through the second smooth deflector surface 102 fully covers the described frame region 142 of described Presentation Function lamination 14 from the region of cover plate 10 outgoing.This will make, when display panel shows, can not demonstrate the frame of display panel 10.
In an embodiment of the present invention, frame region 142 is the non-display functional area of the periphery of Presentation Function lamination 14, such as, can be the region for holding sealed plastic box or peripheral circuit.
In one example, the refractive index of described wall 13 can be less than the refractive index of described first substrate 11 and cover plate 10, and the first smooth deflector surface 111 bends along the direction towards cover plate 10 together with the second smooth deflector surface 102.
Fig. 2 is be illustrated the first smooth deflector surface 111 and the second smooth deflector surface 102 to the deflecting action of light with the light of the edge pixel 144 of the image display area 141 from Presentation Function lamination 14.Assuming that the light 151 of edge pixel 144 rightmost side is A1 through first substrate 11 in the incident angle at the first smooth deflector surface 111 place, refraction angle is A2, and the refractive index of first substrate is n1, and the refractive index of wall 13 is n2, then according to refraction law, have
When n2 is less than n1, the edge towards substrate 10 deflects by the light reflected through the first smooth deflector surface 111.The degree of deflection (such as by (A2-A1) represented) of the first smooth deflector surface 111 to light 151 depends on the ratio of n2 and n1.Exemplarily, the width x of frame region 142 and the thickness d of wall 13 can be determined the degree of deflection of light according to the first smooth deflector surface 111.Such as, when hope can cover frame region 142 completely through the light that the first smooth deflector surface 111 deflects, the width x of frame region 142 and the thickness d of wall 13 can be made to meet following relation:
Wherein gd is the thickness of cover plate 10.If consider certain allowance, the width x of frame region 142 and the thickness d of wall 13 also can be made to meet following relation:
Exemplarily, when hope be display panel 100 retain a narrow frame time, the width x of frame region 142 and the thickness d of wall 13 also can be made to meet following relation:
In addition, because the degree of deflection of the first smooth deflector surface 111 to light 151 also depends on incident angle A1, and incident angle A1 is subject to the impact of the first smooth deflector surface 111 in the curvature at the incoming position place of light 151.Therefore, in practice, can by reasonably configuring refractive index n1, the refractive index n2 of wall 13 of first substrate 11, the parameter such as width x, the thickness d of wall 13, the curvature of the first smooth deflector surface 111 of frame region 142 obtains the frame narrowing of expectation or the display effect of Rimless.
Similarly, assuming that the light 152 of edge pixel 144 leftmost side is B1 through first substrate 11 in the incident angle at the first smooth deflector surface 111 place, refraction angle is B2, then according to refraction law, have
Equally, when n2 is less than n1, light 152 also deflects by the edge of the first smooth deflector surface 111 towards substrate 10.The degree of deflection (such as by (B2-B1) represented) of the first smooth deflector surface 111 to light 152 also depends on the ratio of n2 and n1.Equally, according to refraction law and geometric relationship, in practice, also can by reasonably configuration as the refractive index n1 of first substrate 11, the refractive index n2 of wall 13, the width x of frame region 142, the parameter such as width p, the thickness d of wall 13, the curvature of the first smooth deflector surface 111 of edge pixel 144 obtain the frame narrowing of expectation or the display effect of Rimless.Concrete reckoning repeats no more.
Exemplarily, the sine value that described first smooth deflector surface 111 can be configured to the incident angle of light on the first smooth deflector surface 111 making vertically to inject from the marginal portion of the image display area 141 of Presentation Function lamination 14 first substrate 11 is less than the ratio of the refractive index of wall 13 and the refractive index of first substrate 11.That is, the incident angle of light on the first smooth deflector surface 111 vertically injecting first substrate 11 from the marginal portion of the image display area 141 of Presentation Function lamination 14 is made to be less than the cirtical angle of total reflection.This can prevent the light vertically injecting first substrate 11 from the marginal portion of the image display area 141 of Presentation Function lamination 14 to be totally reflected at the first smooth deflector surface 111, thus ensure that optical efficiency.
At light after the first smooth deflector surface 111 deflects, second time deflection can also be carried out by described second smooth deflector surface 102.Exemplarily, the second smooth deflector surface 102 can be contrary with the yawing moment of the first smooth deflector surface 111 to light to the yawing moment of light.Such as, when the refractive index of wall 13 is less than the refractive index of cover plate 10, the center of the light deflected through the first smooth deflector surface 111 towards cover plate 10 deflects by the second smooth deflector surface 102, as shown in Figure 2.So, when the first smooth deflector surface 111 is roughly the same with the curvature of the second smooth deflector surface 102, the light vertically injecting first substrate 11 from the marginal portion of the image display area 141 of Presentation Function lamination 14, after twice deflection of the first smooth deflector surface 111 and the second smooth deflector surface 102, also can generally perpendicularly penetrate from display panel.Like this, beholder can be made to obtain better visual comfort.
Fig. 3 illustrates another the optional example according to display panel of the present invention.In this example, the refractive index of wall 13 can be greater than the refractive index of first substrate 11 and cover plate 10, and the first smooth deflector surface 111 ' is bending towards the direction of first substrate 11 together with the second smooth deflector surface 102 '.When the refractive index of wall 13 can be greater than the refractive index of first substrate 11 and cover plate 10, first smooth deflector surface 111 ' will be less than incident angle for the refraction angle of the light 15 of the image display area 141 from Presentation Function lamination 14, therefore, in order to realize the deflection of light 15 towards the edge of cover plate 10, the first smooth deflector surface 111 ' and the second smooth deflector surface 102 ' need to bend towards the direction of first substrate 11.Its concrete light deflection way and previous embodiment similar, repeat no more.
Exemplarily, in order to prevent producing total reflection at the second smooth deflector surface 102 ' place, the sine value that described second smooth deflector surface 102 ' can be configured to the incident angle of light on the second smooth deflector surface 102 ' making to deflect through the first smooth deflector surface 111 ' is less than the ratio of the refractive index of cover plate 10 and the refractive index of wall 13, even if this incident angle is less than the cirtical angle of total reflection.
Exemplarily, the smooth deflector surface 102,102 ' of described first smooth deflector surface 111,111 ' and second can be configured to the directional light of the marginal portion of the image display area 141 making to come from Presentation Function lamination 14 is still directional light after the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and second deflects.This can be realized by the degree of crook of the smooth deflector surface 102,102 ' of the smooth deflector surface of adjustment first 111,111 ' and second.This can realize better display effect, avoids the distortion that display panel edge is possible.
Exemplarily, the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and second can have roughly the same degree of crook, also can arrange different degree of crook according to actual.In order to realize designing more accurately, different curvature can be had in the upper different position of the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and/or second.
In addition, under the effect of the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and second, the light beam through overshoot may be extended, contributes to like this covering wider region better, increase shelter width, to realize the display effect of frame narrowing or Rimless better.Such as, schematically illustrate as shown in Figure 4, due to the effect of the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and second, the pixel 144 of the marginal portion of image display area 141 may visually be exaggerated.Visually, the line thickness in the pixel 144 ' of amplifying becomes large than pixel 144 physically.Pixel 145 in the other parts of described image display area 141 then not amplify by the smooth deflector surface 102,102 ' of the first smooth deflector surface 111,111 ' and second.In order to compensate above-mentioned visual enlarge-effect, exemplarily, the pixel 144 of the marginal portion of the image display area 141 of described Presentation Function lamination 14 can be designed to finer and closely woven than the pixel 145 in the other parts of described image display area 141 (as adopted less live width).Like this, the pixel 144 of the marginal portion of image display area 141 can be made visually more to level off to consistent for beholder with the pixel 145 in other parts, prevent the distortion of image border.
