[0016] The present invention provides a display substrate, specifically a display substrate with a double-gate structure, which is used to solve the problem that the double-gate structure saves half of the data lines, which results in the difference in brightness between pixel regions and affects the display quality.
[0017] In order to solve the above technical problems, the present invention provides that the display substrate includes a plurality of pixel repeating units, the number of pixel regions in all the pixel repeating units is the same, and the arrangement of the sub-pixel regions is the same, and each pixel region consists of two adjacent pixels. The row consists of three adjacent sub-pixel regions. Each pixel repeating unit includes 2n rows*3m columns of sub-pixel areas. Since the pixel repeating unit includes integer columns of sub-pixel areas, it overcomes the impact of saving half of the data lines on the brightness of the pixel repeating unit, and ensures that the brightness distribution of all pixel repeating units is consistent. , Overcome the problem of light and dark differences and improve the display quality.
[0018] It should be noted that the brightness distribution of the pixel repeating unit refers to the brightness distribution of all pixel regions of the pixel repeating unit. The elimination of half of the data lines in the double-gate structure will cause the pixel area of the display substrate to have the first brightness and the second brightness. In each pixel repeating unit, the pixel area with the first brightness and the pixel area with the second brightness are distributed according to a certain rule , The distribution rules of the pixel area with the first brightness and the pixel area with the second brightness in all the pixel repeating units are the same.
[0019] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0022] Combine Figure 1-Figure 4 As shown, an embodiment of the present invention provides a display substrate including a plurality of pixel regions 100. The display substrate includes a plurality of gate lines 10 arranged in parallel and a plurality of data lines 20 arranged in parallel. The gate lines 10 extend in the row direction. The gate lines 10 and the data lines 20 are distributed across to define a plurality of sub-pixel regions. The area 100 is composed of three adjacent sub-pixel areas in two adjacent rows. For example, each pixel area 100 is composed of two adjacent rows of adjacent sub-pixel areas R, G, and B. The three primary colors of R, G, and B are combined to achieve color display.
[0023] The display substrate adopts a double-gate structure: combined figure 1 with image 3 As shown, there are two gate lines 10 between two adjacent rows of sub-pixel regions. For the same row of sub-pixel regions, there are two sub-pixel regions between two adjacent data lines 20. Since the number of data lines 20 of the double gate structure is halved, the number of corresponding driving chips is halved, which can reduce the cost.
[0024] In order to overcome the problem of brightness difference between pixel regions caused by the double-gate structure, the display substrate is provided to include a plurality of pixel repeating units 200. The number of pixel regions 100 in all the pixel repeating units 200 is the same, and the number of sub-pixel regions is the same. The cloth method is the same. When each pixel area 100 is composed of two adjacent rows of sub-pixel area R, sub-pixel area G, and sub-pixel area B, it is specifically the sub-pixel area R, sub-pixel area G, and sub-pixel area in all pixel repeating units 200 The arrangement of B is the same.
[0025] Wherein, each pixel repeating unit 200 includes 2n rows*3m columns of sub-pixel regions, the same column of sub-pixel regions are distributed on the same line parallel to the data line 20, and for each pixel repeating unit 200, each row of sub-pixel regions includes 3m columns of sub-pixels, each column of sub-pixel areas includes 2n rows of sub-pixel areas, n and m are positive integers, and n and m are not less than 2.
[0026] In the above technical solution, the display area of the display substrate is composed of multiple identical pixel repeating units, and each pixel repeating unit includes an integer column of sub-pixel regions, which overcomes the brightness difference between the pixel regions caused by the double-gate structure omitting half of the data lines , The problem that affects the display quality, ensures that the brightness distribution of all pixel repeating units is consistent, reduces the brightness difference between pixel repeating units, and improves the display quality. Moreover, there is no need to sacrifice the aperture ratio, which solves the contradiction between the aperture ratio of the dual-gate structure and the difference in pixel brightness distribution.
[0027] In order to realize that the pixel repeating unit 200 includes an integer column of sub-pixel regions, all the sub-pixel regions of the pixel repeating unit 200 may be located between the two data lines 20, combined image 3 with Figure 4 Shown. It can also be set that for one pixel repeating unit 200, all the corresponding data lines 20 are located between two adjacent columns of sub-pixel regions, combining figure 1 with figure 2 Shown. Wherein, the data line 20 corresponding to the pixel repeating unit 200 means that a part of the data line 20 is located in the area where the pixel repeating unit 200 is located.
[0028] It should be noted that, in the embodiment of the present invention, the sub-pixel regions in the same row are distributed on the same line parallel to the gate line 10, and the sub-pixel regions in the same column are distributed on the same line parallel to the data line 20. The gate line 10 The sum data line 20 can be a straight line, a broken line or a curve, etc., which is not limited herein.
[0029] In this embodiment, the data line 20 has a polyline structure, and the data line 20 includes a first part located in a region where a pixel repeating unit 200 is located, and the first part includes at least two sub-line segments. For each pixel repeating unit 200, in the extending direction of the gate line 10, there are at least two rows of sub-pixel areas between two adjacent sub-line segments, and the sub-pixels between two adjacent sub-line segments can be set according to display needs. The number of rows in the region.
[0030] In the above technical solution, the double-gate structure saves half of the data lines, which will cause the pixel area of the display substrate to have the first brightness and the second brightness, and in each row of pixel areas, the pixel area with the first brightness and the pixel area with the second brightness The pixel area is distributed at intervals. The sub-pixel areas of the same column are distributed on the same line parallel to the data line 20. The data line 20 of the broken line structure makes the sub-pixel areas of two adjacent rows staggered in the row direction, thereby improving the brightness distribution difference of each row of pixel areas. Therefore, the uniformity of the brightness distribution of each pixel repeating unit 200 is improved, and the display quality is further improved. Specifically, the sub-pixel regions of one row are arranged in one-to-one correspondence with the regions between the two adjacent sub-pixel regions of another row, and the three sub-pixel regions of two adjacent rows are arranged in a V shape to form a pixel region 100.
[0031] In this embodiment, all sub-pixel regions of each pixel repeating unit 200 form multiple pixel regions 100, and it can be further configured that each pixel repeating unit 200 includes multiple rows of pixel regions, and two adjacent rows of sub-pixel regions form multiple pixel regions. 100, combined figure 1 with 3 Shown.
[0032] In a specific embodiment, combining Figure 1-Figure 4 As shown, each pixel repeating unit 200 includes 6 rows*6 columns of sub-pixel regions. The data line 20 has a broken line structure. The first part of the area where the pixel repeating unit 200 is located includes a first sub-line segment extending in a first direction and a second sub-line segment extending in a second direction. The first sub-line segment and the second sub-line segment The angle between the line segments is greater than zero.
[0033] Further, for the pixel repeating unit 200, it is set that there are three rows of sub-pixel areas between two adjacent first sub-line segments, and there are also three rows of sub-pixel areas between two adjacent second sub-line segments.
[0034] In this specific embodiment, when the BM difference is 5.9%, the brightness difference between the pixel repeating units 200 can be reduced to 0.8%. As long as the brightness difference between the pixel repeating units 200 is less than 1%, the problem of the brightness difference of the pixel display at low gray levels will not occur.
[0035] In another specific embodiment, each pixel repeating unit includes 4 rows*6 columns of sub-pixel regions. The gate line is also a broken line structure. The first part located in the area where the pixel repeating unit is located includes a first sub-line segment extending in a first direction and a second sub-line segment extending in a second direction. The first sub-line segment and the second sub-line segment The angle between is greater than zero.
[0036] Further, for the pixel repeat unit, it is set that there are two rows of sub-pixel areas between two adjacent first sub-line segments, and there are also two rows of sub-pixel areas between two adjacent second sub-line segments.
[0037] Of course, in the actual application process, the number of rows and the number of columns of the sub-pixel area of each pixel repeating unit can be set as needed, as long as the purpose of the present invention can be achieved. The shape of the data line is not limited to the structure in the above specific embodiment.
[0038] It is easy to understand that for a display substrate, the number of pixel regions is fixed. The larger the number of pixel repeating units, the finer the division of the display area, which helps to improve the uniformity of brightness distribution. However, for each pixel repeating unit, the larger the number of pixel regions, the more beneficial it is to improve the uniformity of the brightness distribution of a pixel repeating unit. Specifically, the number of pixel repeating units can be set according to the requirements of the brightness distribution.
[0039] Based on the concept of the present invention, those skilled in the art can also make reasonable adjustments to the technical scheme of the present invention according to the number of sub-pixel areas included in each pixel area without creative work. For example, when each pixel area is composed of four adjacent sub-pixel areas located in two adjacent rows, the pixel repeating unit can be set to include 2n rows*4m columns of sub-pixel areas, which will not be detailed here.
[0040] An embodiment of the present invention also provides a display device. The display device includes the display substrate as described above. Since the brightness distribution of different pixel repeating units is consistent, the brightness difference between the pixel repeating units is reduced, thereby improving the display. The display quality of the device.
[0041] The display device may be a liquid crystal display device, an organic electroluminescence display device or other display devices.
[0042] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principles of the present invention, several improvements and substitutions can be made. These improvements and substitutions It should also be regarded as the protection scope of the present invention.
