Detailed Description
The embodiment of the application provides a display device, as shown in fig. 1, which comprises a display panel and a backlight source 1 arranged on any side of the display panel; the display panel comprises an array substrate 2, wherein the array substrate 2 comprises at least one hollowed-out part 3; the array substrate 2 has a first display area 4 and a second display area 5, the first display area 4 surrounds the hollowed-out portion 3, and a distance between a boundary line between the first display area 4 and the second display area 5 and an edge of the hollowed-out portion 3 is smaller than a preset value;
dividing the first display area 4 into a first subarea 7 and a second subarea 8 along the axis line 6 of the hollowed-out part, wherein the first subarea 7 is positioned at the far end of the backlight source 1, and the second subarea 8 is positioned at the near end of the backlight source 1; i.e. the first sub-area 7 is remote from the backlight 1 with respect to the second sub-area 8;
the pixel aperture ratio of the first subarea 7 is larger than that of the second subarea 8; and/or the transmittance of the pixels located in the first sub-area 7 is greater than the transmittance of the pixels located in the second sub-area 8.
In the display device provided by the embodiment of the application, since the pixel aperture ratio of the first sub-region is greater than the pixel aperture ratio of the second sub-region; and/or the penetration rate of the pixels positioned in the first subarea is greater than that of the pixels positioned in the second subarea, so that the brightness of the first subarea positioned at the far end of the backlight source can be improved, the brightness difference between the first subarea and the second subarea is reduced or even eliminated, the display uniformity is improved, and the display effect and the user experience are improved.
Optionally, the orthographic projection of the hollowed-out portion on the array substrate is circular. In fig. 1, the orthographic projection of the hollowed-out portion 3 on the array substrate is circular, the boundary line of the first display area and the second display area encloses a circle, the axis line 6 is parallel to one side of the display panel where the backlight source 1 is arranged, so that the area of the first sub-area 7 is equal to the area of the second sub-area 8, and the first sub-area 7 and the second sub-area 8 are symmetrical along the axis line 6.
When the orthographic projection of the hollowed-out part is circular, a camera and other shapes can be arranged on the hollowed-out part to form a circular element, so that the shape of the hollowed-out part can be matched with the shape of the element, and the area of a non-display area of the element to be arranged in the display device is ensured to be minimized.
It should be noted that, in this embodiment of the present application, the array substrate includes only one hollow portion 3, and the orthographic projection of the hollow portion 3 is illustrated as a circle, in fact, for a display device, the array substrate 2 may include a plurality of hollow portions 3, so that a plurality of elements may be disposed, the shapes of different hollow portions 3 may be different, and the shape of each hollow portion 3 may be specifically designed according to the shape of the element that needs to be disposed. The hollowed-out portion 3 of the display panel may be formed by hole digging on the array substrate 2, or may be formed by photolithography in a region where the hollowed-out portion is required to be formed, which is not limited in this application.
In fig. 1, the boundary line between the first display area 4 and the second display area 5 is illustrated as a circle, however, the boundary between the first display area 4 and the second display area 5 may be other shapes, and may be specifically divided according to the shape of the hollowed-out portion. The distance from the boundary line between the first display area 4 and the second display area 5 to the edge of the hollowed-out portion 3 is smaller than a preset value, so that a first sub-area 7 which needs to be adjusted for the pixel aperture ratio and/or the pixel penetration ratio can be divided in the display area 4, and the preset value can be specifically selected according to the shape and the size of the hollowed-out portion 3. The size of the area of the first display area 4 is related to factors such as the size of the hollowed-out portion 3.
Optionally, the light transmission area of the pixels of the first sub-region 7 is larger than the light transmission area of the pixels of the second sub-region 8. Therefore, the pixel aperture ratio of the first subarea 7 is larger than that of the second subarea 8, the brightness of the first subarea 7 positioned at the far end of the backlight source 1 can be improved, the brightness difference between the first subarea 7 and the second subarea 8 is reduced or even eliminated, the display uniformity is improved, and the display effect and the user experience are improved. Taking the orthographic projection of the hollowed-out portion 3 on the array substrate 2 as an example, the pixels of the first display area 4 are arranged as shown in fig. 2, and the unit pixel opening area 9 is the light transmission area of the pixel, as can be seen from fig. 2, the opening area of all the pixels in the first sub-area 7 is larger than the opening area of all the pixels in the second sub-area 8, so that the light transmission area of the pixels in the first sub-area 7 is larger than the light transmission area of the pixels in the second sub-area 8.
Optionally, defining a as a light transmission area of the first sub-region 7 pixel, and B as a light transmission area of the second sub-region 8 pixel, where the light transmission area of the first sub-region 7 pixel and the light transmission area of the second sub-region 8 pixel satisfy the following conditions:
A＝B×K；
wherein K is a preset parameter, K >1.
It should be noted that, when the pixel aperture ratios of the first sub-area 7 and the second sub-area 8 are consistent and the pixel penetration ratios are consistent, the brightness of the second sub-area 8 will be higher than that of the first sub-area 7, and in this embodiment of the present application, the preset parameter K may be specifically set according to the brightness difference between the first sub-area 7 and the second sub-area 8. The specific difference of the brightness of the first sub-area 7 and the second sub-area 8 is related to the size of the hollowed-out portion, etc., and the specific difference of the brightness of the first sub-area 7 and the second sub-area 8 can be predetermined through simulation or specific experiments, for example, if the difference of the brightness of the first sub-area 7 and the second sub-area 8 is a, k=1+a. In this way, a=b×k corresponds to compensation of the luminance of the first sub-region 7, and since the areas of the first sub-region 7 and the second sub-region 8 are equal, the luminance difference between the first sub-region 7 and the second sub-region 8 can be eliminated.
Optionally, in the first display area 4, along the radial extending direction of the hollowed-out portion 3, the light transmission area of the unit pixel gradually increases, and/or the size of the unit pixel gradually increases.
It should be noted that, when the orthographic projection of the hollowed-out portion 3 on the array substrate 2 is non-rectangular such as circular, the first display area 4 surrounding the hollowed-out portion 3 is easy to generate display saw teeth, and for the situation that the orthographic projection of the hollowed-out portion 3 on the array substrate 2 is circular, the display device as shown in fig. 2 provided in this embodiment of the application redesigns pixels around the hollowed-out portion 3 according to the shape of the hollowed-out portion 3, and along the radial extension direction of the hollowed-out portion 3, the light transmission area of the unit pixel and the size of the unit pixel are gradually increased, so that the display saw teeth around the hollowed-out portion can be eliminated, and the display effect is further improved.
The backlight source of the display device shown in fig. 1 is disposed at the bottom of the display panel, that is, the display device adopts a side-in backlight source, and when the aperture ratio and/or the transmittance of the first sub-area 7 in fig. 1 are not adjusted, the backlight light path simulation diagram of the display device shown in fig. 1 is shown in fig. 3, the circular black area in fig. 3 is the hollowed-out portion 3, and the brightness of the area surrounded by the white dotted line above the hollowed-out portion 3 is lower than that of the second sub-area. Optionally, the first sub-area 7 in fig. 1 includes a compensation area 10, that is, an area surrounded by a white dotted line above the hollowed-out portion 3 is taken as the compensation area 10, and the compensation area 10 is used for performing brightness compensation on the area so that the brightness of the first sub-area 7 is consistent with the brightness of the second sub-area 8;
wherein the compensation area 10 is defined by a line segment passing through three points, the three points including: two points located at the edge of the hollowed-out portion 3 and one point on a straight line 11 perpendicular to the axis line 6.
According to the display device provided by the embodiment of the application, the brightness compensation can be performed on the compensation area 10 in the first subarea 7, so that the brightness difference between the first subarea 7 and the second subarea 8 can be reduced or even eliminated, the display uniformity is improved, and the display effect and the user experience are improved.
The shape and area of the compensation region 10 are related to the shape and area of the hollowed-out portion 3. The brightness compensation of the compensation region 10 is performed such that the brightness of the first sub-region 7 is identical to the brightness of the second sub-region 8, for example, the aperture ratio of the compensation region 10 may be made larger than the aperture ratio of the second sub-region 8 or the first display region 4 except for the compensation region 10, which is equal to the compensation region area. Specifically, the pixel light transmission area of the compensation region 10 may be made larger than the light transmission area of the second sub-region 8 or the region of the first display region 4 other than the compensation region 10, which is equal to the area of the compensation region 10. Further, defining the light transmission area of the compensation area 10 as a ', and defining the light transmission area of the second sub-area 8 or the first display area 4, except for the compensation area 10, as B', which is equal to the area of the compensation area 10, so that a '=b' ×k; wherein K is a preset parameter, K >1. The preset parameter K is consistent with the preset parameter K mentioned above, and will not be described again.

In a specific design of the pixels of the array substrate, only the compensation region 10 may be brightness-compensated, i.e., only the width of the first black matrix 12 and/or the second black matrix 13 of the compensation region 10 in fig. 4 may be adjusted. Specifically, the width of the first black matrix 12 and/or the second black matrix 13 in the compensation region 10 is adjusted as shown in fig. 5 to 7.
