Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a pixel arrangement structure and a display panel. Background Technology

[0002] With the development of display technology, the resolution of display panels has gradually increased. Currently, the resolution of display panels has reached 8K (7680*4320) and above. With the display panel size remaining unchanged, the increase in resolution leads to a decrease in aperture ratio, thereby reducing the transmittance of the display panel. Therefore, the 8-Domain pixel architecture, originally used to improve viewing angle characteristics, cannot be applied to higher resolution products due to the loss of transmittance. It has been replaced by the 4-Domain pixel architecture, but this also leads to a deterioration in viewing angle characteristics, resulting in viewfinder distortion.

[0003] To address this, the original grayscale of subpixels within the effective display area of ​​the display panel is replaced with relatively high and relatively low grayscale values. When viewed from the side, since low grayscale subpixels reduce the degree of brightness variation, the more low grayscale subpixels there are, the better the color shift is improved. However, increasing the number of low grayscale pixels can affect the image sharpness and produce a grainy appearance. Summary of the Invention

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second," etc., may explicitly or implicitly include one or more of the stated features, and thus should not be construed as limiting this application. Furthermore, the term "multiple" refers to two or more.

[0051] This application provides a pixel arrangement structure and a display panel, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application.

[0052] For details, please refer to Figures 1-3 , Figure 1 This is a schematic diagram of one pixel arrangement structure provided in this application; Figure 2 This is another schematic diagram of the pixel arrangement structure provided in this application; Figure 3 This is a schematic diagram of the gamma curves before and after color cast improvement provided in this application.

[0053] like Figure 1 As shown, the display panel is set to display high grayscale sub-pixels H and low grayscale sub-pixels L, and the ratio of the number of high grayscale sub-pixels H to low grayscale sub-pixels L is 1:1, that is, H:L=1:1.

[0054] like Figure 2As shown, the display panel is set to display high grayscale sub-pixels H and low grayscale sub-pixels L, and the ratio of the number of high grayscale sub-pixels H to low grayscale sub-pixels L is 1:2, that is, H:L=1:2.

[0055] It should be noted that if the image display data input to the display panel is 8-bit binary, it will generate 28 original gray levels from darkest to brightest. This results in 256 different gray levels (for example, denoted as gray level 0 to gray level 255). Any gray level from gray level 0 to gray level 255 can be called an original gray level. Each original gray level corresponds to a high gray level and a low gray level. The gray level value of the high gray level is greater than or equal to the gray level value of the original gray level, and the gray level value of the low gray level is less than or equal to the gray level value of the original gray level.

[0056] In this application, a high grayscale subpixel refers to a subpixel displayed at a higher grayscale level than the original grayscale level, and a low grayscale subpixel refers to a subpixel displayed at a lower grayscale level than the original grayscale level. Here, grayscale refers to the brightness level generated by a subpixel after power-on control. That is, the pixel arrangement structures provided in this application are all the arrangement structures after power-on.

[0057] like Figure 3 As shown, curve A represents the initial frontal gamma curve, i.e., the frontal gamma curve without the view-to-color shift compensation algorithm; curve B represents the initial side-view gamma curve, i.e., the side-view gamma curve without the view-to-color shift compensation algorithm; curve C represents the side-view gamma curve when H:L = 1:1; and curve D represents the side-view gamma curve when H:L = 1:2. It can be seen that the higher the proportion of low grayscale sub-pixels L, the smaller the difference between side-view and front-view brightness, and the better the color shift improvement. However, to further improve the view-to-color shift improvement effect, more low grayscale sub-pixels L must be added, which will produce obvious graininess in the image quality and reduce display quality.

[0058] To address this, this application provides a novel pixel arrangement structure. The pixel arrangement structure includes at least one pixel group. Each pixel group includes multiple sub-pixels arranged in an array. In the pixel group, the ratio of high-grayscale sub-pixels to low-grayscale sub-pixels is 1:2 or 1:3. The low-grayscale sub-pixels include a first low-grayscale sub-pixel, and the number of high-grayscale sub-pixels in every adjacent N rows of sub-pixels is equal to the number of the first low-grayscale sub-pixels. N is an integer multiple of 2, 3, or 1.

[0059] In this embodiment, on the one hand, since the ratio of high grayscale subpixels to low grayscale subpixels is 1:2 or 1:3, the increased number of low grayscale subpixels further enhances the viewing angle compensation effect. On the other hand, in the pixel group, since the number of high grayscale subpixels and the number of first low grayscale subpixels are equal in every adjacent N rows of subpixels, the display brightness of every adjacent N rows of subpixels in the pixel group is more uniform, thereby improving the viewing angle compensation effect while reducing image graininess and improving the visual effect.

[0060] It should be noted that the orientation or positional relationship indicated by "row", "column", "row direction" and "column direction" in the embodiments of this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of facilitating the description of this application and simplifying the description, and should not be construed as a limitation of this application.

[0061] In the embodiments of this application, sub-pixel 101 can be a red sub-pixel, a blue sub-pixel, a green sub-pixel, a yellow sub-pixel, etc. For example, in some embodiments, in pixel group 10, multiple sub-pixels 101 located in the same column have the same color, and multiple sub-pixels 101 located in the same row are repeatedly arranged in any combination of red, green, and blue sub-pixels as units. For another example, in the following embodiments of this application, the pixel unit includes three sub-pixels, which are divided into a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Of course, this application is not limited to these.

[0062] For details, please refer to Figure 4 , Figure 4 This is a first structural schematic diagram of the pixel arrangement structure provided in this application. In this embodiment, the ratio of high grayscale sub-pixels H to low grayscale sub-pixels L in pixel group 10 is 1:2. The low grayscale sub-pixels L include a first low grayscale sub-pixel L1 and a second low grayscale sub-pixel L2. In every adjacent N rows of sub-pixels 101, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, and the number of second low grayscale sub-pixels L2 are all equal.

[0063] It is understood that this embodiment of the application uses one relatively high grayscale and two relatively low grayscales (high grayscale sub-pixel H, first low grayscale sub-pixel L1, and second low grayscale sub-pixel L2) to replace one original grayscale, further widening the difference between the relatively high grayscale and the relatively low grayscale, thereby further improving the viewing angle compensation effect. Furthermore, since the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, and the number of second low grayscale sub-pixels L2 in each adjacent N rows of sub-pixels 101 are all equal, the display brightness of the pixel group 10 is more uniform, thereby improving the viewing angle compensation effect while reducing image graininess and improving the visual effect.

[0064] In this embodiment of the application, for the same original gray level, the gray level values ​​of the high gray level sub-pixel H, the first low gray level sub-pixel L1, and the second low gray level sub-pixel L2 are all different. For example, the gray level value of the high gray level sub-pixel H is greater than the gray level value of the first low gray level sub-pixel L1, and the gray level value of the first low gray level sub-pixel L1 is greater than the gray level value of the second low gray level sub-pixel L2.

[0065] In some embodiments, in each column of sub-pixels 101 of pixel group 10, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, and the number of second low grayscale sub-pixels L2 are all equal. This further improves the uniformity of the arrangement of high grayscale sub-pixels H, first low grayscale sub-pixels L1, and second low grayscale sub-pixels L2 in each column of sub-pixels 101, thereby improving the uniformity of display brightness between adjacent columns of sub-pixels 101 and reducing image graininess.

[0066] In some embodiments, the plurality of sub-pixels 101 in the pixel group 10 are arranged in three rows and nine columns. In each row of sub-pixels 101, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, and the number of second low grayscale sub-pixels L2 are all equal.

[0067] For details, please continue reading. Figure 4 Pixel group 10 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13. The first pixel unit 11 includes a high grayscale sub-pixel H, a first low grayscale sub-pixel L1, and a high grayscale sub-pixel H arranged sequentially along the row direction. The second pixel unit 12 includes a first low grayscale sub-pixel L1, a second low grayscale sub-pixel L2, and a first low grayscale sub-pixel L1 arranged sequentially along the row direction. The third pixel unit 13 includes a second low grayscale sub-pixel L2, a high grayscale pixel H, and a second low grayscale sub-pixel L2 arranged sequentially along the row direction. Each row of sub-pixels 101 includes the first pixel unit 11, the second pixel unit 12, and the third pixel unit 13.

[0068] For example, such as Figure 4 As shown, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction.

[0069] For example, in other embodiments, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction.

[0070] Furthermore, in pixel group 10, multiple sub-pixels 101 located in the same column have the same color, and multiple sub-pixels 101 located in the same row are arranged repeatedly using any combination of red, green, and blue sub-pixels as units. Therefore, in each row or column of sub-pixels 101, the number of high-grayscale sub-pixels H, the first low-grayscale sub-pixel L1, and the second low-grayscale sub-pixel L2 corresponding to the red sub-pixels is the same. In each row or column of sub-pixels 101, the number of high-grayscale sub-pixels H, the first low-grayscale sub-pixels L1, and the second low-grayscale sub-pixels L2 corresponding to the green sub-pixels is the same. In each row or column of sub-pixels 101, the number of high-grayscale sub-pixels H, the first low-grayscale sub-pixels L1, and the second low-grayscale sub-pixels L2 corresponding to the blue sub-pixels is the same. Therefore, in this embodiment, the high grayscale sub-pixel H, the first low grayscale sub-pixel L1, and the second low grayscale sub-pixel L2 corresponding to the red sub-pixel, green sub-pixel, and blue sub-pixel are distributed more evenly, thereby achieving color uniformity.

[0071] Please see Figure 5 , Figure 5 This is a schematic diagram of the second structure of the pixel arrangement structure provided in this application. (and...) Figure 4 The difference in the pixel arrangement structure 100 shown is that, in this embodiment, the first pixel unit 11 includes three high grayscale sub-pixels H arranged sequentially along the row direction. The second pixel unit 12 includes three first low grayscale sub-pixels L1 arranged sequentially along the row direction. The third pixel unit 13 includes three second low grayscale sub-pixels L2 arranged sequentially along the row direction. Each row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13.

[0072] For example, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction.

[0073] For example, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction.

[0074] Furthermore, in pixel group 10, multiple sub-pixels 101 located in the same column have the same color, and multiple sub-pixels 101 located in the same row are arranged repeatedly using any combination of red, green, and blue sub-pixels as units. Therefore, in each row or column of sub-pixels 101, the number of high-grayscale sub-pixels H, first low-grayscale sub-pixels L1, and second low-grayscale sub-pixels L2 corresponding to the red sub-pixels are all the same. Thus, in this embodiment, the distribution of high-grayscale sub-pixels H, first low-grayscale sub-pixels L1, and second low-grayscale sub-pixels L2 corresponding to the red sub-pixels is more uniform, thereby achieving color uniformity. The same applies to blue and green sub-pixels, which will not be elaborated further here.

[0075] Please see Figure 6 , Figure 6 This is a schematic diagram of the third structure of the pixel arrangement structure provided in this application. (and...) Figure 4 The difference in the pixel arrangement structure 100 shown is that, in this embodiment, the first pixel unit 11 includes a high grayscale sub-pixel H, a first low grayscale sub-pixel L1, and a second low grayscale sub-pixel L2 arranged sequentially along the row direction. The second pixel unit 12 includes a first low grayscale sub-pixel L1, a second low grayscale sub-pixel L2, and a high grayscale pixel H arranged sequentially along the row direction. The third pixel unit 13 includes a second low grayscale pixel L2, a high grayscale pixel H, and a first low grayscale pixel L1 arranged sequentially along the row direction. Each row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13.

[0076] For example, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction.

[0077] For example, in pixel group 10, the first row of sub-pixels 101 includes a first pixel unit 11, a second pixel unit 12, and a third pixel unit 13 arranged sequentially along the row direction. The second row of sub-pixels 101 includes a third pixel unit 13, a first pixel unit 11, and a second pixel unit 12 arranged sequentially along the row direction. The third row of sub-pixels 101 includes a second pixel unit 12, a third pixel unit 13, and a first pixel unit 11 arranged sequentially along the row direction.

[0078] Furthermore, in pixel group 10, multiple sub-pixels 101 located in the same column have the same color, and multiple sub-pixels 101 located in the same row are arranged repeatedly using any combination of red, green, and blue sub-pixels as units. Therefore, in each row or column of sub-pixels 101, the number of high-grayscale sub-pixels H, first low-grayscale sub-pixels L1, and second low-grayscale sub-pixels L2 corresponding to the red sub-pixels are all the same. Thus, in this embodiment, the distribution of high-grayscale sub-pixels H, first low-grayscale sub-pixels L1, and second low-grayscale sub-pixels L2 corresponding to the red sub-pixels is more uniform, thereby achieving color uniformity. The same applies to blue and green sub-pixels, which will not be elaborated further here.

[0079] Please see Figure 7 , Figure 7 This is a schematic diagram of the fourth structure of the pixel arrangement structure provided in this application. (and...) Figure 4 The difference in the pixel arrangement structure 100 shown is that, in this embodiment, the multiple sub-pixels 101 in the pixel group 10 are arranged in three rows and twelve columns. In one row of sub-pixels 101, the second low grayscale sub-pixels L2 and the high grayscale sub-pixels H are arranged alternately. In the other two rows of sub-pixels 101, the number of high grayscale sub-pixels H is the same as the number of second low grayscale sub-pixels L2.

[0080] Understandably, for the same original grayscale, the grayscale value of the high grayscale sub-pixel H is greater than the grayscale value of the first low grayscale sub-pixel L1, and the grayscale value of the first low grayscale sub-pixel L1 is greater than the grayscale value of the second low grayscale sub-pixel L2. That is, for the same original grayscale, the brightness of the high grayscale sub-pixel H is higher than the brightness of the first low grayscale sub-pixel L1; the brightness of the first low grayscale sub-pixel L1 is higher than the brightness of the second low grayscale sub-pixel L2. Therefore, in one row of sub-pixels 101, the second low grayscale sub-pixels L2 and the high grayscale sub-pixels H are arranged alternately, and in the other two rows of sub-pixels 101, the number of high grayscale sub-pixels H is the same as the number of second low grayscale sub-pixels L2; ​​this achieves complementarity of brightness at different grayscale levels, thereby improving the brightness uniformity of multiple sub-pixels 101 and reducing image graininess.

[0081] Specifically, such as Figure 7As shown, pixel group 10 includes a first pixel unit 11 and a second pixel unit 12. Both the first pixel unit 11 and the second pixel unit 12 are arranged in a row of six columns. In the first pixel unit 11, high grayscale sub-pixels H and first low grayscale sub-pixels L1 are arranged alternately. In the second pixel unit 12, first low grayscale sub-pixels L1 and second low grayscale sub-pixels L2 are arranged alternately.

[0082] The first row of sub-pixels 101 includes a first pixel unit 11 and a second pixel unit 12 arranged sequentially along the row direction. In the second row of sub-pixels 101, a second low grayscale sub-pixel L2 and a high grayscale sub-pixel H are arranged alternately. The third row of sub-pixels 101 includes a second pixel unit 12 and a first pixel unit 11 arranged sequentially along the row direction.

[0083] In this embodiment, the number of high grayscale sub-pixels H in the first row is the same as the number of high grayscale sub-pixels H in the third row. The number of first low grayscale sub-pixels L1 in the first row is the same as the number of first low grayscale sub-pixels L1 in the third row. The number of second low grayscale sub-pixels L2 in the first row is the same as the number of second low grayscale sub-pixels L2 in the third row. That is, in the first row of sub-pixels 101 and the third row of sub-pixels 101, the high grayscale sub-pixels H, the first low grayscale sub-pixels L1, and the second low grayscale sub-pixels L2 are more evenly distributed, further improving the brightness uniformity of the pixel group 10 and reducing the graininess of the image.

[0084] Please see Figure 8 , Figure 8 This is a schematic diagram of the fifth pixel arrangement structure provided in this application. (and...) Figure 1 The difference in the pixel arrangement structure 100 shown is that, in this embodiment, the ratio of the number of high grayscale sub-pixels H to the number of low grayscale sub-pixels L in pixel group 10 is 1:3. The low grayscale sub-pixels L include a first low grayscale sub-pixel L1, a second low grayscale sub-pixel L2, and a third low grayscale sub-pixel L3. Specifically, in every adjacent N rows of sub-pixels 101, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of third low grayscale sub-pixels L3 are all equal.

[0085] This embodiment of the application utilizes one relatively high grayscale and three relatively low grayscales (high grayscale sub-pixel H, first low grayscale sub-pixel L1, second low grayscale sub-pixel L2, and third low grayscale sub-pixel L3) to replace one original grayscale, further widening the difference between the relatively high and relatively low grayscales, thereby further improving the viewing angle compensation effect. Furthermore, since the number of high grayscale sub-pixels H, first low grayscale sub-pixels L1, second low grayscale sub-pixels L2, and third low grayscale sub-pixels L3 in each adjacent N rows of sub-pixels 101 is equal, the display brightness of adjacent N rows of sub-pixels 101 in the pixel group 10 is more uniform, thereby improving the viewing angle compensation effect while reducing image graininess and improving the visual effect.

[0086] In some embodiments of this application, for the same original grayscale, the grayscale values ​​of the high grayscale sub-pixel H, the first low grayscale sub-pixel L1, the second low grayscale sub-pixel L2, and the third low grayscale sub-pixel L3 are all different. For example, the grayscale value of the high grayscale sub-pixel H is greater than the grayscale value of the first low grayscale sub-pixel L1, the grayscale value of the first low grayscale sub-pixel L1 is greater than the grayscale value of the second low grayscale sub-pixel L2, and the grayscale value of the second low grayscale sub-pixel L2 is greater than the grayscale value of the third low grayscale sub-pixel L3.

[0087] like Figure 8 As shown, in each pair of adjacent rows of sub-pixels 101 of pixel group 10, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of third low grayscale sub-pixels L3 are all equal. In each column of sub-pixels 101, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of second low grayscale sub-pixels L3 are all equal.

[0088] As a result, the distribution of sub-pixels 101 in each column and in each adjacent row of pixel group 10 is more uniform, thereby improving the uniformity of display brightness.

[0089] Furthermore, in pixel group 10, multiple sub-pixels 101 located in the same column have the same color, and multiple sub-pixels 101 located in the same row are arranged repeatedly using any combination of red, green, and blue sub-pixels as units. Therefore, in every two rows of sub-pixels 101 or in every column of sub-pixels 101, the number of high grayscale sub-pixels H, first low grayscale sub-pixels L1, second low grayscale sub-pixels L2, and third low grayscale sub-pixels L3 corresponding to the red sub-pixels are all the same. Thus, in this embodiment, the distribution of high grayscale sub-pixels H, first low grayscale sub-pixels L1, second low grayscale sub-pixels L2, and third low grayscale sub-pixels L3 corresponding to the red sub-pixels (green or blue sub-pixels) is more uniform, thereby achieving color uniformity.

[0090] In one embodiment, the pixel group 10 includes a first pixel unit 11, a second pixel unit 12, a third pixel unit 13, and a fourth pixel unit 14. The first pixel unit 11 includes two high grayscale sub-pixels H and a first low grayscale sub-pixel L1. The second pixel unit 12 includes a high grayscale sub-pixel H and two first low grayscale pixels L1. The third pixel unit 13 includes two second low grayscale sub-pixels L2 and a third low grayscale pixel L3. The fourth pixel unit 14 includes a second low grayscale pixel L2 and two third low grayscale pixels L3. In the pixel group 10, the first pixel unit 11 and the second pixel unit 12 are arranged diagonally, and the third pixel unit 13 and the fourth pixel unit 14 are also arranged diagonally.

[0091] Specifically, along the row direction, in the first pixel unit 11, the first low grayscale sub-pixel L1 is located between two high grayscale sub-pixels H; in the second pixel unit 12, the high grayscale sub-pixel H is located between two first low grayscale sub-pixels L1; in the third pixel unit 13, the third low grayscale sub-pixel L3 is located between two second low grayscale sub-pixels L2; ​​and in the fourth pixel unit 14, the second low grayscale sub-pixel L2 is located between two third low grayscale sub-pixels L3.

[0092] Please see Figure 9 , Figure 9 This is a schematic diagram of the sixth structure of the pixel arrangement structure provided in this application. (and...) Figure 8 The difference in the pixel arrangement structure 100 shown is that, in this embodiment, in each row of sub-pixels 101 within the pixel group 10, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of third low grayscale sub-pixels L3 are all equal. In every six adjacent columns of sub-pixels 101, the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of third low grayscale sub-pixels L3 are all equal.

[0093] It is understandable that the grayscale values ​​of the high grayscale sub-pixel H, the first low grayscale sub-pixel L1, the second low grayscale sub-pixel L2, and the third low grayscale sub-pixel L3 are all different. This embodiment sets the number of high grayscale sub-pixels H, the number of first low grayscale sub-pixels L1, the number of second low grayscale sub-pixels L2, and the number of third low grayscale sub-pixels L3 in each row of sub-pixels 101 to be equal, ensuring that the pixel distribution of each row of sub-pixels 101 in pixel group 10 is the same, thereby improving the brightness uniformity of pixel group 10 and reducing image graininess.

[0094] Specifically, such as Figure 9As shown, in one embodiment, pixel group 10 includes a first pixel unit 11 and a second pixel unit 12. Both the first pixel unit 11 and the second pixel unit 12 are arranged in a row of six columns. In the first pixel unit 11, high grayscale sub-pixels H and first low grayscale sub-pixels L1 are alternately arranged. In the second pixel unit 12, second low grayscale sub-pixels L2 and third low grayscale sub-pixels L3 are alternately arranged. In pixel group 10, the first pixel unit 11 and the second pixel unit 12 are alternately arranged in the same row of sub-pixels 101; the first pixel unit 11 and the second pixel unit 12 are alternately arranged in the same column of sub-pixels 101.

[0095] Understandably, in some embodiments, the grayscale value of the high grayscale sub-pixel H is greater than the grayscale value of the first low grayscale sub-pixel L1, the grayscale value of the first low grayscale sub-pixel L1 is greater than the grayscale value of the second low grayscale sub-pixel L2, and the grayscale value of the second low grayscale sub-pixel L2 is greater than the grayscale value of the third low grayscale sub-pixel L3. Therefore, in the first pixel unit 11, the brightness of the high grayscale sub-pixel H and the first low grayscale sub-pixel L1 can compensate for each other, and in the second pixel unit 12, the brightness of the second low grayscale sub-pixel L2 and the third low grayscale sub-pixel L3 can compensate for each other, thereby reducing the graininess of the image. Furthermore, the first pixel unit 11 and the second pixel unit 12 are arranged alternately along both the row and column directions, further improving the brightness uniformity of the pixel group 10, thereby improving the visual effect.

[0096] Correspondingly, such as Figure 10 As shown, this application also provides a display panel 1000. The display panel 1000 includes a plurality of sub-pixels 101. The plurality of sub-pixels 101 are arranged according to the pixel arrangement structure 100 as described in any of the above embodiments, and the specific details can be found in the above embodiments, which will not be repeated here.

[0097] In the display panel 1000 provided in this application, a plurality of sub-pixels 101 are arranged according to the pixel arrangement structure 100 described in any of the above embodiments. While improving the viewing angle compensation effect of the display panel 1000, it can reduce the graininess of the image, improve the visual effect, and enhance the quality of the display panel 1000.
