Description

Technical Field

[0001] Embodiments of the present disclosure relate to an array substrate and a display device. Background Art

[0002] With the continuous development of display technology, people have higher and higher requirements for the resolution of display devices. Due to the advantages of high display quality, the application range of high-resolution display devices is also getting wider and wider. Generally, the resolution of a display device can be improved by reducing the size of pixels and reducing the spacing between pixels. However, the reduction of the size of pixels and the spacing between pixels also places higher and higher requirements on the precision of the manufacturing process, which will lead to an increase in the difficulty of the manufacturing process of the display device and the increase in the manufacturing cost.

[0003] On the other hand, sub-pixel rendering (SPR) technology can take advantage of the difference in the human eye's resolution of sub-pixels of different colors, change the conventional red, green, and blue sub-pixels that simply define a pixel, and share certain sub-pixels of color that are not sensitive to resolution between different pixels. By using a relatively small number of sub-pixels, it can simulate the same pixel resolution performance, thereby reducing the difficulty and cost of the production process. Summary of the invention

[0004] The disclosed embodiments provide an array substrate and a display device. In the array substrate, the distance between a first color sub-pixel and a second color sub-pixel is different from the distance between the same first color sub-pixel and a third color sub-pixel; that is, the distance between the first color sub-pixel and the second color sub-pixel and the third color sub-pixel to which the human eye is more sensitive can be set closer. Therefore, when the array substrate is used to display vertical lines, since the distance between the first color sub-pixel and the sub-pixel to which the human eye is sensitive is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the displayed image, and making the lines of the displayed image more continuous and natural.

[0005] At least one embodiment of the present disclosure provides an array substrate, comprising: a plurality of sub-pixel groups, each of the sub-pixel groups comprising two first color sub-pixels, one second color sub-pixel and one third color sub-pixel, wherein in each of the sub-pixel groups, a first line connecting centers of two first color sub-pixels intersects with a second line connecting centers of the second color sub-pixel and the third color sub-pixel, and a length of an orthographic projection of a third line connecting centers of the first color sub-pixel and the second color sub-pixel on the second line is different from a length of an orthographic projection of a fourth line connecting centers of the first color sub-pixel and the third color sub-pixel on the second line.

[0006] For example, in the array substrate provided in one embodiment of the present disclosure, the length of the orthographic projection of a third line connecting the center of the first color sub-pixel and the center of the second color sub-pixel on the second line is greater than the length of the orthographic projection of a fourth line connecting the center of the first color sub-pixel and the center of the third color sub-pixel on the second line.

[0007] For example, in the array substrate provided in one embodiment of the present disclosure, in each of the sub-pixel groups, in the direction of the third line, no other sub-pixels are arranged between the first color sub-pixel and the second color sub-pixel, and in the direction of the fourth line, no other sub-pixels are arranged between the first color sub-pixel and the third color sub-pixel.

[0008] For example, an array substrate provided in an embodiment of the present disclosure further includes: a sub-pixel interval, which is arranged between two adjacent sub-pixels, and the sub-pixel is any one of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel.

[0009] For example, in the array substrate provided in an embodiment of the present disclosure, the second connecting line, the third connecting line and the fourth connecting line form a non-equilateral triangle.

[0010] For example, in an array substrate provided in an embodiment of the present disclosure, the length of the third connection line is not equal to the length of the fourth connection line.

[0011] For example, in an array substrate provided in an embodiment of the present disclosure, the two first color sub-pixels are mirror-symmetrical with respect to the second connecting line.

[0012] For example, in an array substrate provided in an embodiment of the present disclosure, the plurality of sub-pixel groups are arranged along a first direction to form a plurality of sub-pixel group rows, the plurality of sub-pixel groups are arranged along a second direction intersecting the first direction to form a plurality of sub-pixel group columns, and two adjacent sub-pixel group columns are staggered. In the sub-pixel group columns, two adjacent sub-pixel groups include a first sub-pixel group and a second sub-pixel group, and the shortest distance between the center of the first color sub-pixel in the first sub-pixel group and the center of the first color sub-pixel in the second sub-pixel group is less than the length of the first connecting line.

[0013] For example, in an array substrate provided in an embodiment of the present disclosure, the length of the first connecting line is less than 90 micrometers.

[0014] For example, in an array substrate provided by an embodiment of the present disclosure, two adjacent first-color sub-pixels in a first direction overlap with a straight line extending along the first direction.

[0015] For example, in an array substrate provided in an embodiment of the present disclosure, centers of two first color sub-pixels in the first sub-pixel group and centers of two first color sub-pixels in the second sub-pixel group are located on the same straight line.

[0016] For example, in an array substrate provided in an embodiment of the present disclosure, the plurality of sub-pixel groups are arranged along a first direction to form a plurality of sub-pixel group rows, the plurality of sub-pixel groups are arranged along a second direction intersecting the first direction to form a plurality of sub-pixel group columns, and two adjacent sub-pixel group columns are staggered. In the sub-pixel group columns, two adjacent sub-pixel groups include a first sub-pixel group and a second sub-pixel group, and the ratio of the distance between the vertices of the two closest first color sub-pixels in the first sub-pixel group and the second sub-pixel group that are farthest from each other to the size of the second color sub-pixel in the extension direction of the first connecting line is 0.8-1.2.

[0017] For example, in an array substrate provided in an embodiment of the present disclosure, the shape of the first color sub-pixel is a non-centrosymmetric polygon, the shape of the second color sub-pixel is a non-centrosymmetric polygon, and the shape of the third color sub-pixel is a non-centrosymmetric polygon.

[0018] For example, in the array substrate provided in one embodiment of the present disclosure, the ratio of the size of the shape of the first color sub-pixel in the extension direction of the first line to the size of the shape of the first color sub-pixel in the extension direction of the second line is in the range of 1.6-2.8; and / or the ratio of the size of the shape of the second color sub-pixel in the extension direction of the first line to the size of the shape of the second color sub-pixel in the extension direction of the second line is in the range of 4.3-6.7; and / or the ratio of the size of the shape of the third color sub-pixel in the extension direction of the first line to the size of the shape of the third color sub-pixel in the extension direction of the second line is in the range of 0.4-0.76.

[0019] For example, in the array substrate provided in one embodiment of the present disclosure, in each of the sub-pixel groups, the orthographic projection of the second color sub-pixel on the first line overlaps with the orthographic projection of the first color sub-pixel on the first line, and the orthographic projection of the third color sub-pixel on the first line does not overlap with the orthographic projection of the first color sub-pixel on the first line.

[0020] For example, in the array substrate provided in an embodiment of the present disclosure, in each of the sub-pixel groups, the orthographic projection of the first color sub-pixel on the second line overlaps with the orthographic projection of the third color sub-pixel on the second line.

[0021] For example, in the array substrate provided in an embodiment of the present disclosure, at least one of the shapes of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel includes a pair of parallel edges, and the pair of parallel edges includes two parallel edges.

[0022] For example, in the array substrate provided in one embodiment of the present disclosure, at least one of the shape of the second color sub-pixel and the shape of the third color sub-pixel includes a pair of parallel edges, the pair of parallel edges includes a first parallel edge and a second parallel edge, the length of the first parallel edge is greater than the length of the second parallel edge, and the distance between the first parallel edge and the first connecting line is greater than the distance between the second parallel edge and the first connecting line.

[0023] For example, in the array substrate provided in an embodiment of the present disclosure, at least one of the shape of the second color sub-pixel and the shape of the third color sub-pixel is symmetrical about the second connecting line.

[0024] For example, in the array substrate provided in an embodiment of the present disclosure, at least one of the shapes of the second color sub-pixel and the third color sub-pixel includes a hexagon, the polygon includes two vertices, the distance between the two vertices is the maximum size of the polygon in the second direction, and the polygon is divided by a line connecting the two vertices into a first part and a second part located on both sides of the line, and the areas of the first part and the second part are not equal.

[0025] For example, in an array substrate provided in an embodiment of the present disclosure, the polygon includes a first side and a second side, the first side and the second side are parallel and parallel to the line connecting the two vertices, and the length of the first side is greater than that of the second side, the first part is a part on one side of the first side of the polygon, the second part is a part on one side of the second side of the polygon, and the size of the first part in the first direction is smaller than the size of the second part in the first direction.

[0026] For example, in an array substrate provided in an embodiment of the present disclosure, the area of ​​the second color sub-pixel is greater than the area of ​​the third color sub-pixel.

[0027] For example, in the array substrate provided in one embodiment of the present disclosure, the shape of the first color sub-pixel includes a pair of parallel edges, the pair of parallel edges includes two parallel edges, and in one of the sub-pixel groups, the length of one of the two parallel edges close to the second color sub-pixel is shorter than the length of one of the two parallel edges close to the third color sub-pixel.

[0028] For example, in an array substrate provided in an embodiment of the present disclosure, the shape of the first color sub-pixel is symmetrical with respect to the extending direction of the first connection line.

[0029] For example, an array substrate provided in an embodiment of the present disclosure further includes: a base substrate; a first color pixel electrode, a second color pixel electrode and a third color pixel electrode, which are located on the base substrate; a pixel defining layer, which is located on a side of the first color pixel electrode, the second color pixel electrode and the third color pixel electrode away from the base substrate, and includes a first opening, a second opening and a third opening, wherein the first opening exposes the first color pixel electrode, the second opening exposes the second color pixel electrode, and the third opening exposes the third color pixel electrode; a first color light-emitting layer, which is located on a side of the pixel defining layer away from the first color pixel electrode, and covers a portion of the first color pixel electrode exposed by the first opening through the first opening; a second color light-emitting layer, which is located on a side of the pixel defining layer away from the second color pixel electrode, and covers a portion of the second color pixel electrode exposed by the second opening through the second opening; and a third color light-emitting layer, which is located on a side of the pixel defining layer away from the third color pixel electrode, and covers a portion of the third color pixel electrode exposed by the third opening through the third opening, wherein the shape and size of the first color sub-pixel are defined by the first opening, the shape and size of the second color sub-pixel are defined by the second opening, and the shape and size of the third color sub-pixel are defined by the third opening.

[0030] For example, in the array substrate provided in an embodiment of the present disclosure, two first color light-emitting layers of two adjacent first color sub-pixels in the extension direction of the first connection line are integrated into the same first color integrated light-emitting layer, and the orthographic projection of the first color integrated light-emitting layer on the base substrate simultaneously covers the two first openings.

[0031] At least one embodiment of the present disclosure further provides a display device, which includes any of the above array substrates. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0048] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0049] Although the sub-pixel rendering (SPR) technology can use a relatively small number of sub-pixels to simulate the same pixel resolution performance, thereby reducing the difficulty and cost of the production process, the pixel arrangement structure using the sub-pixel rendering (SPR) technology will produce some display defects, such as grainy display images and discontinuous lines in the display images.

[0050] Figure 1 Schematic diagram of an array substrate. Figure 1 As shown, the array substrate 10 includes a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13. The colors of light emitted by the first color sub-pixel 11 and the third color sub-pixel 13 may be colors that the human eye is sensitive to, that is, when the human eye performs visual synthesis, the colors of light emitted by the first color sub-pixel 11 and the third color sub-pixel 13 account for a higher proportion. Figure 1 As shown, when the array substrate is used for vertical lines, since the distance between the first color sub-pixel and the third color sub-pixel is relatively far, the "fluctuation" of the vertical lines seen by the human eye is relatively strong, thus causing a grainy feeling in the displayed image and making the lines of the displayed image discontinuous.

[0051] In this regard, an embodiment of the present disclosure provides an array substrate and a display device. The array substrate includes a plurality of sub-pixel groups, each of which includes two first color sub-pixels, one second color sub-pixel, and one third color sub-pixel; in each sub-pixel group, a first line connecting the centers of the two first color sub-pixels intersects with a second line connecting the centers of the second color sub-pixel and the third color sub-pixel, and the length of the positive projection of the third line connecting the centers of the first color sub-pixel and the second color sub-pixel on the second line is different from the length of the positive projection of the fourth line connecting the centers of the same first color sub-pixel and the third color sub-pixel on the second line. Thus, in the extension direction of the second line, the distance between the first color sub-pixel and the second color sub-pixel is different from the distance between the same first color sub-pixel and the third color sub-pixel; that is, in the extension direction of the second line, the first color sub-pixel can be closer to the second color sub-pixel or the third color sub-pixel. Therefore, when the array substrate is used to display vertical lines extending along the extension direction of the first connecting line, and the first color sub-pixels are all colors that the human eye is sensitive to, since the first color sub-pixel can be closer to the second color sub-pixel and the third color sub-pixel that the human eye is more sensitive to, the "sense of fluctuation" of the vertical lines seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the displayed image and making the lines of the displayed image more continuous and natural.

[0052] The array substrate and the display device provided by the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0053] An embodiment of the present disclosure provides an array substrate. Figure 2A A schematic plan view of an array substrate provided in one embodiment of the present disclosure; Figure 2B FIG. 1 is a plan view of another array substrate provided by an embodiment of the present disclosure. Figure 2A As shown, the array substrate 100 includes a plurality of sub-pixel groups 120; each sub-pixel group 120 includes two first color sub-pixels 121, one second color sub-pixel 122, and one third color sub-pixel 123. For example, the first color sub-pixel 121 is configured to emit light of a first color, the second color sub-pixel 122 is configured to emit light of a second color, and the third color sub-pixel 123 is configured to emit light of a third color.

[0054] For example, the first color may be green, the second color may be blue, and the third color may be red. Of course, the embodiments of the present disclosure include but are not limited to this.

[0055] like Figure 2AAs shown, in each sub-pixel group 120, the first line CL1 of the centers of two first color sub-pixels 121 intersects with the second line CL2 of the centers of the second color sub-pixel 122 and the third color sub-pixel 123, and the length L1 of the orthographic projection of the third line CL3 of the center of a first color sub-pixel 121 and the center of the second color sub-pixel 122 on the second line CL2 is different from the length L2 of the orthographic projection of the fourth line CL4 of the center of the same first color sub-pixel 121 and the center of the third color sub-pixel 123 on the second line CL2. It should be noted that the above-mentioned "center" refers to the brightness center or geometric center of the effective light-emitting area of ​​the sub-pixel.

[0056] In the array substrate provided in the embodiment of the present disclosure, Figure 2B As shown, the length L1 of the orthographic projection of the third line CL3 between the center of a first color sub-pixel 121 and the center of the second color sub-pixel 122 on the second line CL2 is greater than the length L2 of the orthographic projection of the fourth line CL4 between the center of the same first color sub-pixel 121 and the center of the third color sub-pixel 123 on the second line CL2; that is, in the extension direction of the second line CL2, the distance between the first color sub-pixel 121 and the second color sub-pixel 122 is greater than the distance between the first color sub-pixel 121 and the third color sub-pixel 123; in the extension direction of the second line CL2, the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer. Therefore, when the array substrate is used to display a vertical line extending along the extension direction of the first connection line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the first color sub-pixel 121 is closer to the third color sub-pixel 123, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the display image and making the lines of the display image more continuous and natural.

[0057] In the array substrate provided in the embodiment of the present disclosure, Figure 2B As shown, two first color sub-pixels 121 in one sub-pixel group 120 can share the second color sub-pixel 122 and the third color sub-pixel 123 to form two pixel points, so that a relatively small number of sub-pixels can be used to achieve a higher pixel resolution.

[0058] In some examples, the length of the orthographic projection of a third line connecting the center of a first color sub-pixel and the center of a second color sub-pixel on the second line is greater than the length of the orthographic projection of a fourth line connecting the center of the same first color sub-pixel and the center of a third color sub-pixel on the second line, and the luminous efficiency of the second color sub-pixel is less than the luminous efficiency of the third color sub-pixel. In the field of organic light-emitting displays, the luminous efficiency of a light-emitting element that emits blue light is generally less than the luminous efficiency of a light-emitting element that emits red light, and the human eye is more sensitive to red light than to blue light. For example, the luminous efficiency of the first color sub-pixel may be greater than the luminous efficiency of the third color sub-pixel.

[0059] In some examples, the light emitting area of ​​a single second color sub-pixel is larger than the light emitting area of ​​a single third color sub-pixel. Due to factors such as lifespan and light emitting efficiency, the light emitting area of ​​a sub-pixel emitting blue light is usually larger than the light emitting area of ​​a sub-pixel emitting red light.

[0060] In some examples, the light emitting area of ​​a single third color sub-pixel may be larger than the light emitting area of ​​a single first color sub-pixel.

[0061] In some examples, the luminous intensity per unit area of ​​the second color subpixel is less than the luminous intensity per unit area of ​​the third color subpixel, and the luminous intensity per unit area of ​​the third color subpixel is less than the luminous intensity per unit area of ​​the first color subpixel.

[0062] In some examples, the wavelength of light emitted by the second color subpixel is less than the wavelength of light emitted by the third color subpixel; in addition, the wavelength of light emitted by the first color subpixel is between the wavelength of light emitted by the second color subpixel and the wavelength of light emitted by the third color subpixel.

[0063] In some examples, the ratio of the length L1 of the orthographic projection of the third line CL3 between the center of the first color sub-pixel 121 and the center of the second color sub-pixel 122 on the second line CL2 to the length L2 of the orthographic projection of the fourth line CL4 between the center of the first color sub-pixel 121 and the center of the third color sub-pixel 123 on the second line CL2 may be in the range of 1-3. Figure 2B As shown, the ratio of the length L1 of the orthographic projection of the third line CL3 between the center of the first color sub-pixel 121 and the center of the second color sub-pixel 122 on the second line CL2 to the length L2 of the orthographic projection of the fourth line CL4 between the center of the first color sub-pixel 121 and the center of the third color sub-pixel 123 on the second line CL2 can be in the range of 1-1.5.

[0064] In some examples, such as Figure 2A As shown, the second line CL2, the third line CL3 and the fourth line CL4 form a non-equilateral triangle.

[0065] In some examples, such as Figure 2A As shown, the length of the third line CL3 is not equal to the length of the fourth line CL4.

[0066] In some examples, such as Figure 2A As shown, the two first color sub-pixels 121 are mirror-symmetrical with respect to the second connection line CL2. Thus, the array substrate can increase the symmetry of the two pixel points in the sub-pixel group.

[0067] For example, Figure 2A As shown, the second color sub-pixel 122 and the third color sub-pixel 123 are also mirror-symmetrical with respect to the second line CL2, that is, the second color sub-pixel 122 and the third color sub-pixel 123 are mirror-symmetrical with respect to a straight line extending along the extension direction of the second line CL2.

[0068] In some examples, such as Figure 2A As shown, a plurality of sub-pixel groups 120 are arranged along a first direction to form a plurality of sub-pixel group rows 131, and are arranged along a second direction intersecting the first direction to form a plurality of sub-pixel group columns 132, and two adjacent sub-pixel group columns 132 are staggered. It should be noted that the above-mentioned "staggered arrangement" means that the two adjacent sub-pixel group columns 132 are not aligned, but are staggered by a certain distance in the second direction. For example, two adjacent sub-pixel group columns 132 can be staggered by 1 / 2 pitch, and the above-mentioned pitch is the distance between the centers of the second color sub-pixels in the two adjacent sub-pixel groups in the second direction.

[0069] In some examples, such as Figure 2A As shown, in the sub-pixel column 132, two adjacent sub-pixel groups 120 include a first sub-pixel group 1201 and a second sub-pixel group 1202; the shortest distance L3 between the center of the first color sub-pixel 121 in the first sub-pixel group 1201 and the center of the first color sub-pixel 121 in the second sub-pixel group 1202 is less than the length L4 of the first line CL1, and the length L4 of the first line CL1 is less than 90 microns, for example, less than 78 microns or less than 56 microns. Since the retina recognition limit of the human eye is 78 microns, when the length of the first line CL1 is less than 78 microns, that is, when the distance between the centers of the two first color sub-pixels 121 is less than 78 microns, the human eye will not easily recognize the uneven graininess caused by the difference in spacing between the two first color sub-pixels 121, which is beneficial to the screen display effect.

[0070] In some examples, such as Figure 2AAs shown, the shortest distance L4 between the center of the first color sub-pixel 121 in the first sub-pixel group 1201 and the center of the first color sub-pixel 121 in the second sub-pixel group 1202 is less than or equal to the shortest distance L5 between the centers of two first color sub-pixels 121 adjacent in the first direction. It should be noted that the two first color sub-pixels adjacent in the first direction may be a lower first color sub-pixel in a sub-pixel group in a sub-pixel group row and an upper first color sub-pixel in a sub-pixel group adjacent to the above sub-pixel group in an adjacent sub-pixel group row.

[0071] In some examples, such as Figure 2A and Figure 2B As shown, two first color sub-pixels adjacent to each other in the first direction overlap with a straight line extending along the first direction. That is, a straight line extending along the first direction can simultaneously pass through two first color sub-pixels adjacent to each other in the first direction.

[0072] In some examples, the centers of two adjacent first color sub-pixels in the first direction may be located on a straight line extending along the first direction, that is, a straight line extending along the first direction may simultaneously pass through the centers of two adjacent first color sub-pixels in the first direction. Figure 2A As shown, the sum of the shortest distance L3 between the center of the first color sub-pixel 121 in the first sub-pixel group 1201 and the center of the first color sub-pixel 121 in the second sub-pixel group 1202 and the length L4 of the first connection line CL1 may be twice the pitch.

[0073] For example, the first direction and the second direction mentioned above are perpendicular to each other, and the first direction and the second direction are perpendicular to each other, including the case where the first direction and the second direction are strictly perpendicular, and also including the case where the angle between the first direction and the second direction is in the range of 80-100 degrees.

[0074] For example, Figure 2A As shown, the first direction may be the extension direction of the second line CL2, and the second direction may be the extension direction of the first line CL1. Of course, the embodiments of the present disclosure include but are not limited to this.

[0075] In some examples, such as Figure 2A As shown, the centers of the two first color sub-pixels 121 in the first sub-pixel group 1201 and the centers of the two first color sub-pixels 121 in the second sub-pixel group 1202 are located on the same straight line.

[0076] For example, Figure 2A As shown, the centers of all the first color sub-pixels 121 in one sub-pixel group column 132 may be located on the same straight line.

[0077] In some examples, such as Figure 2BAs shown, the shape of the first color sub-pixel 121 is a non-centrosymmetric polygon, the shape of the second color sub-pixel 122 is a non-centrosymmetric polygon, and the shape of the third color sub-pixel 123 is a non-centrosymmetric polygon. Thus, the area of ​​the array substrate can be fully utilized, thereby improving the aperture ratio.

[0078] For example, the number of sides of each of the shapes of the first color sub-pixel 121 , the second color sub-pixel 122 , and the third color sub-pixel 123 described above is greater than five.

[0079] In some examples, at least one of the shape of the first color sub-pixel 121 , the shape of the second color sub-pixel 122 , and the shape of the third color sub-pixel 123 includes a pair of parallel sides, and the pair of parallel sides includes two parallel sides.

[0080] like Figure 2B As shown, the shape of the first color sub-pixel 121 includes a parallel edge pair 1214, and the parallel edge pair 1214 includes two parallel edges 1214A and 1214B; the shape of the second color sub-pixel 122 includes a parallel edge pair 1224, and the parallel edge pair 1224 includes two parallel edges 1224A and 1224B; the shape of the third color sub-pixel 123 includes a parallel edge pair 1234, and the parallel edge pair 1234 includes two parallel edges 1234A and 1234B.

[0081] Therefore, when the array substrate is manufactured by using a fine metal mask (FMM), the extension direction of the parallel edges can be the stretching direction of the fine metal mask (FMM), which is conducive to the transmission of the tension force of the fine metal mask (FMM), thereby improving the product yield. Figure 2A and Figure 2B The shapes of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel in the array substrate shown all include parallel edge pairs, but the embodiments of the present disclosure include but are not limited to this. The shape of at least one of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel includes a parallel edge pair, which may also be beneficial to the transmission of the fine metal mask (FMM) tensioning force, thereby improving the product yield.

[0082] For example, Figure 2A As shown, at least one of the shapes of the first color sub-pixel 121, the second color sub-pixel 122 and the third color sub-pixel 123 may include parallel sides parallel to the second direction, in which case the second direction may be the stretching direction of the fine metal mask (FMM).

[0083] In some examples, at least one of the shapes of the second color sub-pixel 122 and the shapes of the third color sub-pixel 123 includes a pair of parallel edges, the pair of parallel edges includes a first parallel edge and a second parallel edge, the length of the first parallel edge is greater than the length of the second parallel edge, and the distance between the first parallel edge and the first line is greater than the distance between the second parallel edge and the first line.

[0084] In some examples, such as Figure 2A As shown, in one sub-pixel group, the length of one of the two parallel sides close to the second color sub-pixel 122 is shorter than the length of one of the two parallel sides close to the third color sub-pixel 123 .

[0085] like Figure 2B As shown, the shape of the second color sub-pixel 122 includes a parallel side pair 1224, the parallel side pair 1224 includes a first parallel side 1224A and a second parallel side 1224B, the length of the first parallel side 1224A is greater than the second parallel side 1224B, and the distance between the first parallel side 1224A and the first line CL1 is greater than the distance between the second parallel side 1224B and the first line CL1; the shape of the third color sub-pixel 123 includes a parallel side pair 1234, the parallel side pair 1234 includes a first parallel side 1234A and a second parallel side 1234B, the length of the first parallel side 1234A is greater than the second parallel side 1234B, and the distance between the first parallel side 1234A and the first line CL1 is greater than the distance between the second parallel side 1234B and the first line CL1. Since two first color sub-pixels 121 are arranged in the space between the second color sub-pixel 122 and the third color sub-pixel 123, the above arrangement can fully utilize the space and improve the aperture ratio.

[0086] In some examples, such as Figure 2B As shown, at least one of the shapes of the second color sub-pixel 122 and the third color sub-pixel 123 is symmetrical about the second connection line CL2.

[0087] In some examples, such as Figure 2B As shown, the area of ​​the second color sub-pixel 122 is larger than the area of ​​the third color sub-pixel 123. Due to the differences in the structural design and material system of the light-emitting device, there are differences in the lifespans of sub-pixels of different colors (such as the first color sub-pixel 121, the second color sub-pixel 122, and the third color sub-pixel 123 mentioned above). Therefore, by setting the area of ​​the second color sub-pixel 122 to be larger than the third color sub-pixel 123, the above-mentioned lifespan differences can be balanced and the overall lifespan of the array substrate can be improved.

[0088] In some examples, such as Figure 2BAs shown, the shape of the first color sub-pixel 121 includes a first oblique side 1215 and a first right angle 1216, the shape of the second color sub-pixel 122 includes a second oblique side 1225, the first oblique side 1215 and the second oblique side 1225 are arranged relatively parallel, and the shape of the third color sub-pixel 123 includes a third oblique side 1235, and the third oblique side 1235 is arranged relatively to the first right angle 1216. Therefore, since the area of ​​the second color sub-pixel 122 is larger than the area of ​​the third color sub-pixel 123, the first oblique side 1215 of the first color sub-pixel 121 and the second oblique side 1225 of the second color sub-pixel 122 can be arranged relatively to increase the area of ​​the first color sub-pixel and the second color sub-pixel as much as possible under the limitation of process accuracy, and the first right angle 1216 of the first color sub-pixel 121 and the third oblique side 1235 of the third color sub-pixel 123 are arranged relatively to make full use of the interval between the first color sub-pixel 121 and the third color sub-pixel 123, so as to make full use of the area of ​​the array substrate and improve the aperture ratio.

[0089] Figure 3 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 3 As shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the centers of the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Similarly, in the extending direction of the second connecting line CL2, the distance between the first color sub-pixel 121 and the second color sub-pixel 122 is greater than the distance between the first color sub-pixel 121 and the third color sub-pixel 123; that is, in the extending direction of the second connecting line CL2, the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer. Therefore, when the array substrate is used to display a vertical line extending along the extension direction of the first connection line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the first color sub-pixel 121 is closer to the third color sub-pixel 123, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the display image and making the lines of the display image more continuous and natural.

[0090] In some examples, such as Figure 3As shown, the shape of the second color sub-pixel 122 is a polygon 1220, and the polygon 1220 includes two vertices V1 and V2. The distance between the two vertices V1 and V2 is the maximum size of the polygon 1220 in the second direction. The polygon 1220 is divided by the line connecting the two vertices V1 and V2 into a first part P1 and a second part P2 located on both sides of the line, and the areas of the first part P1 and the second part P2 are not equal.

[0091] For example, Figure 3 As shown, the polygon includes a first side and a second side, the first side and the second side are parallel and parallel to the line connecting the two vertices, and the length of the first side is greater than the second side, the first part is the part of the side where the first side of the polygon is located, and the second part is the part of the side where the second side of the polygon is located, and the size of the first part P1 in the first direction is smaller than the size of the second part P2 in the first direction.

[0092] In some examples, such as Figure 3 As shown, the shape of the third color sub-pixel 123 is a polygon 1230, and the polygon 1230 includes two vertices V3 and V4. The distance between the two vertices V3 and V4 is the maximum size of the polygon 1220 in the second direction. The polygon 1240 is divided by the line connecting the two vertices V3 and V4 into a first part P3 and a second part P4 located on both sides of the line, and the areas of the first part P3 and the second part P4 are not equal.

[0093] For example, Figure 3 As shown, the size of the first portion P3 in the first direction is smaller than the size of the second portion P4 in the first direction.

[0094] In some examples, such as Figure 3 As shown, the shape of the first color sub-pixel 121 is symmetrical with respect to the extending direction of the first line CL1.

[0095] For example, Figure 3 As shown, the shape of the first color sub-pixel 121 includes a right-angle symmetrical pentagon, which is symmetrical about the first line CL1; the base of the right-angle symmetrical pentagon is located on the side of the vertex of the right-angle symmetrical pentagon away from the second line CL2.

[0096] In some examples, such as Figure 3 As shown, the order of the second color sub-pixel 122 and the third color sub-pixel 123 in the extending direction of the second line CL2 can be interchanged.

[0097] In some examples, such as Figure 3As shown, the shape of the first color sub-pixel 121 includes a parallel edge pair 1214, and the parallel edge pair 1214 includes two parallel edges 1214A and 1214B; the shape of the second color sub-pixel 122 includes a parallel edge pair 1224, and the parallel edge pair 1224 includes two parallel edges 1224A and 1224B; the shape of the third color sub-pixel 123 includes a parallel edge pair 1234, and the parallel edge pair 1234 includes two parallel edges 1234A and 1234B. Therefore, when the array substrate is manufactured by using a fine metal mask (FMM), the extension direction of the parallel edges can be the stretching direction of the fine metal mask (FMM), which can be beneficial to the transmission of the tension force of the fine metal mask (FMM), thereby improving the product yield.

[0098] In some examples, such as Figure 3 As shown, the shape of the second color sub-pixel 122 includes a hexagon, the hexagon includes a parallel edge group and two opposite edge groups, the parallel edge group includes two parallel edges arranged in parallel to each other, and each opposite edge group includes two opposite edges arranged in opposite directions. Similarly, the shape of the third color sub-pixel 123 also includes a hexagon, the hexagon includes a parallel edge group and two opposite edge groups, the parallel edge group includes two parallel edges arranged in parallel to each other, and each opposite edge group includes two opposite edges arranged in opposite directions.

[0099] For example, Figure 3 As shown, the first color sub-pixel 121 is configured to emit green light; the second color sub-pixel 122 is configured to emit blue light, and the third color sub-pixel 123 is configured to emit red light.

[0100] Figure 4A FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 4AAs shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the centers of the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Similarly, in the extending direction of the second connecting line CL2, the distance between the first color sub-pixel 121 and the second color sub-pixel 122 is greater than the distance between the first color sub-pixel 121 and the third color sub-pixel 123; that is, in the extending direction of the second connecting line CL2, the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer. Therefore, when the array substrate is used to display a vertical line extending along the extension direction of the first connection line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the first color sub-pixel 121 is closer to the third color sub-pixel 123, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the display image and making the lines of the display image more continuous and natural.

[0101] like Figure 4A As shown, the shape of the third color sub-pixel 123 includes a parallel side pair 1234, the parallel side pair 1234 includes a first parallel side 1234A and a second parallel side 1234B, the length of the first parallel side 1234A is greater than the second parallel side 1234B, and the distance between the first parallel side 1234A and the first line CL1 is greater than the distance between the second parallel side 1234B and the first line CL1. Since two first color sub-pixels 121 are arranged in the space between the second color sub-pixel 122 and the third color sub-pixel 123, the above arrangement can fully utilize the space and improve the aperture ratio.

[0102] For example, Figure 4A As shown, the shape of the third color sub-pixel 123 includes a pair of parallel sides 1234 , and the pair of parallel sides 1234 includes a first parallel side 1234A and a second parallel side 1234B. The length of the first parallel side 1234A is equal to the length of the second parallel side 1234B.

[0103] Figure 4B FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 4BAs shown, the shapes of the first color sub-pixel 121, the second color sub-pixel 122 and the third color sub-pixel 123 are all bilaterally symmetrical. Further, the shapes of the first color sub-pixel 121, the second color sub-pixel 122 and the third color sub-pixel 123 are all bilaterally symmetrical hexagons.

[0104] For example, Figure 4B As shown, the ratio of the size in the second direction to the size in the first direction (aspect ratio) of the shapes of the second color sub-pixel 122 and the third color sub-pixel 123 is smaller than the ratio of the size in the second direction to the size in the first direction (aspect ratio) of the shape of the first color sub-pixel 121.

[0105] For example, the second color sub-pixel 122 and the third color sub-pixel 123 may have substantially the same size in the second direction as in the first direction; that is, the second color sub-pixel 122 and the third color sub-pixel 123 may be regular hexagons.

[0106] Figure 5 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 5 As shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Therefore, when the array substrate is used to display a vertical line extending along the extending direction of the first connecting line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the graininess of the displayed image, and making the lines of the displayed image more continuous and natural.

[0107] like Figure 5 As shown, the shape of the first color sub-pixel 121 includes a rectangle, such as Figure 5As shown, the shape of the second color sub-pixel 122 includes a "T" shape, and the T shape includes a first rectangular portion 1221 extending along the first direction, a second rectangular portion 1222 extending along the second direction, and an arc portion 1223 located at the connection position between the first rectangular portion 1221 and the second rectangular portion 1222; the shape of the third color sub-pixel 123 includes a rectangle. Therefore, the shapes of the first color sub-pixel and the third color sub-pixel are simple and easy to manufacture; and the shape of the second color sub-pixel is conducive to improving the space utilization of the array substrate, so that the layout can be optimized.

[0108] Likewise, if Figure 5 As shown, the shape of the first color sub-pixel 121 includes a parallel edge pair 1214, the parallel edge pair 1214 includes two parallel edges 1214A and 1214B, and the length of the parallel edge 1214A is equal to the length of the parallel edge 1214B; the shape of the second color sub-pixel 122 includes a parallel edge pair 1224, the parallel edge pair 1224 includes two parallel edges 1224A and 1224B, and the length of the parallel edge 1224A is greater than the length of the parallel edge 1224B; the shape of the third color sub-pixel 123 includes a parallel edge pair 1234, and the parallel edge pair 1234 includes two parallel edges 1234A and 1234B. Therefore, when the array substrate is manufactured by using a fine metal mask (FMM), the extension direction of the parallel edges can be the stretching direction of the fine metal mask (FMM), which can be beneficial to the transmission of the tension force of the fine metal mask (FMM), thereby improving the product yield.

[0109] Figure 6 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 6 As shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Therefore, when the array substrate is used to display a vertical line extending along the extending direction of the first connecting line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the graininess of the displayed image, and making the lines of the displayed image more continuous and natural.

[0110] like Figure 6As shown, the shape of the first color sub-pixel 121 includes a rectangle, the shape of the second color sub-pixel 122 includes a "T" shape, and the T shape includes a first rectangular portion 1221 extending along the first direction and a second rectangular portion 1222 extending along the second direction; the shape of the third color sub-pixel 123 includes a rectangle. Therefore, the shapes of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are simple and easy to manufacture; and the shape of the second color sub-pixel is conducive to improving the space utilization of the array substrate, thereby optimizing the layout.

[0111] Likewise, if Figure 6 As shown, the shape of the first color sub-pixel 121 includes a parallel edge pair 1214, and the parallel edge pair 1214 includes two parallel edges 1214A and 1214B; the shape of the second color sub-pixel 122 includes a parallel edge pair 1224, and the parallel edge pair 1224 includes two parallel edges 1224A and 1224B; the shape of the third color sub-pixel 123 includes a parallel edge pair 1234, and the parallel edge pair 1234 includes two parallel edges 1234A and 1234B. Therefore, when the array substrate is manufactured by using a fine metal mask (FMM), the extension direction of the parallel edges can be the stretching direction of the fine metal mask (FMM), which can be beneficial to the transmission of the tension force of the fine metal mask (FMM), thereby improving the product yield.

[0112] Figure 7 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 7 As shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Therefore, when the array substrate is used to display a vertical line extending along the extending direction of the first connecting line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the graininess of the displayed image, and making the lines of the displayed image more continuous and natural.

[0113] like Figure 7As shown, the shapes of the first color sub-pixel 121, the second color sub-pixel 122 and the third color sub-pixel 123 are all rectangular. Therefore, the shapes of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel are simple and easy to manufacture; and the shape of the second color sub-pixel is conducive to improving the space utilization of the array substrate, thereby optimizing the layout.

[0114] In some examples, such as Figure 7 As shown, the third color sub-pixel 123 extends beyond the first connection line CL1 of the two first color sub-pixels 121, so that the distance between the first color sub-pixel 121 and the second color sub-pixel 123 in the direction perpendicular to the first connection line CL1 is closer. Therefore, when the array substrate is used to display a vertical line extending along the extension direction of the first connection line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the graininess of the displayed image, and making the lines of the displayed image more continuous and natural.

[0115] Figure 8 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Figure 8 As shown, in each sub-pixel group 120, the first connecting line CL1 of the centers of the two first color sub-pixels 121 intersects with the second connecting line CL2 of the centers of the second color sub-pixel 122 and the third color sub-pixel 123, and the length L1 of the orthographic projection of the third connecting line CL3 of the centers of any first color sub-pixel 121 and the second color sub-pixel 122 on the second connecting line CL2 is greater than the length L2 of the orthographic projection of the fourth connecting line CL4 of the centers of the first color sub-pixel 121 and the third color sub-pixel 123 on the second connecting line CL2. Therefore, when the array substrate is used to display a vertical line extending along the extending direction of the first connecting line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are both colors that the human eye is sensitive to, since the distance between the first color sub-pixel 121 and the third color sub-pixel 123 is closer, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the graininess of the displayed image, and making the lines of the displayed image more continuous and natural.

[0116] like Figure 8As shown, the shape of the first color sub-pixel 121 is a pentagon with a right-angled bottom angle symmetry, the shape of the second color sub-pixel 122 is a trapezoid, the trapezoid includes a pair of parallel sides 1224, the pair of parallel sides 1224 includes two parallel sides 1224A and 1224B; the shape of the third color sub-pixel 123 is a hexagon, the hexagon includes a pair of parallel sides 1234, the pair of parallel sides 1234 includes two parallel sides 1234A and 1234B. Therefore, when the array substrate is manufactured using a fine metal mask (FMM), the extension direction of the parallel sides can be the stretching direction of the fine metal mask (FMM), which can be beneficial to the transmission of the tensioning force of the fine metal mask (FMM), thereby improving the product yield.

[0117] Fig. 9 A schematic plan view of another array substrate provided in one embodiment of the present disclosure; Fig.10 An array substrate provided by an embodiment of the present disclosure is Fig. 9 Schematic diagram of the cross section along the A-A' direction. Fig. 9 and Fig.10 As shown, the array substrate 100 also includes a base substrate 110; a first color pixel electrode 141, a second color pixel electrode 142 and a third color pixel electrode 143 located on the base substrate 110; a pixel defining layer 150 located on a side of the first color pixel electrode 141, the second color pixel electrode 142 and the third color pixel electrode 143 away from the base substrate 110; and a first color light-emitting layer 161, a second color light-emitting layer 162 and a third color light-emitting layer 163 located on a side of the pixel defining layer 150 away from the base substrate 110. The pixel defining layer 150 includes a first opening 151, a second opening 152, and a third opening 153. The first opening 151 exposes the first color pixel electrode 141, the second opening 152 exposes the second color pixel electrode 142, and the third opening 153 exposes the third color pixel electrode 143. The first color light emitting layer 161 covers the portion of the first color pixel electrode 141 exposed by the first opening 151 through the first opening 151. The second color light emitting layer 162 covers the portion of the second color pixel electrode 142 exposed by the second opening 152 through the second opening 152. The third color light emitting layer 163 covers the portion of the third color pixel electrode 143 exposed by the third opening 153 through the third opening 153. At this time, the shape and size of the first color sub-pixel 121 are defined by the first opening 151, the shape and size of the second color sub-pixel 122 are defined by the second opening 152, and the shape and size of the third color sub-pixel 123 are defined by the third opening 153. It should be noted that the above-mentioned light-emitting layer may include not only a light-emitting film layer, but also functional film layers such as an electron transport layer, an electron injection layer, a hole transport layer, and a hole injection layer.

[0118] In some examples, such as Fig. 9 As shown, the two first color light emitting layers 161 of two adjacent first color sub-pixels 121 can be integrated into the same first color integrated light emitting layer 161. That is, the two first color light emitting layers 161 of the two first color sub-pixels 121 can be formed through the same opening of the same fine mask (FMM).

[0119] For example, Fig. 9 As shown, in the embodiment of the present disclosure, since the first color sub-pixel and the third color sub-pixel in the same sub-pixel group are close to each other, the first color light-emitting layers of the two first color sub-pixels in the same sub-pixel group may not be integrated together. On the contrary, in a sub-pixel column, two adjacent sub-pixel groups include a first sub-pixel group and a second sub-pixel group, and the first color sub-pixel in the first sub-pixel group close to the second sub-pixel group and the first color sub-pixel in the second sub-pixel group close to the first sub-pixel group may be integrated into the same first color integrated light-emitting layer.

[0120] In some examples, such as Fig. 9 As shown, the orthographic projection of the first color integrated light emitting layer 161 on the base substrate 110 covers the two first openings 151 at the same time. Fig. 9 As shown, the first color sub-pixel 121 may include the above-mentioned first color pixel electrode 141 and a first color light-emitting layer 161 arranged on the first color pixel electrode 141; the second color sub-pixel 122 includes the second color pixel electrode 142 and a second color light-emitting layer 162 arranged on the second color pixel electrode 142; the third color sub-pixel 123 includes the third color pixel electrode 143 and a third color light-emitting layer 163 arranged on the third color pixel electrode 143.

[0121] For example, the first color pixel electrode 141 is configured to drive the first color light-emitting layer 161 to emit light of the first color; the second color pixel electrode 142 is configured to drive the second color light-emitting layer 162 to emit light of the second color; and the third color pixel electrode 143 is configured to drive the third color light-emitting layer 163 to emit light of the third color.

[0122] It should be noted that the shape and size of the first color sub-pixel mentioned above may be the shape and size of the effective light-emitting area of ​​the first color sub-pixel, which may be limited by the first via hole mentioned above. Therefore, the shape of the first color pixel electrode may be different from the shape of the first color sub-pixel mentioned above. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the first color pixel electrode may also be the same as the shape of the first color sub-pixel mentioned above. Similarly, the shape and size of the second color sub-pixel mentioned above may be the shape and size of the effective light-emitting area of ​​the second color sub-pixel, which may be limited by the second via hole mentioned above. Therefore, the shape of the second color pixel electrode may be the same as or different from the shape of the second color sub-pixel mentioned above; and, the shape and size of the third color sub-pixel mentioned above may be the shape and size of the effective light-emitting area of ​​the third color sub-pixel, which may be limited by the third via hole mentioned above. Therefore, the shape of the third color pixel electrode may be the same as or different from the shape of the third color sub-pixel mentioned above.

[0123] On the other hand, the specific shapes of the first color light-emitting layer, the second color light-emitting layer and the third color light-emitting layer can be set according to the preparation process, and the embodiments of the present disclosure are not limited here. For example, the shape of the first color light-emitting layer can be determined by the shape of the mask opening in the preparation process.

[0124] In some examples, such as Fig. 9 and Fig.10 As shown, the size of the first color pixel electrode 141 is larger than the size of the first opening 151, the size of the second color pixel electrode 142 is larger than the size of the second opening 152, and the size of the third color pixel electrode 143 is larger than the size of the third opening 153. In addition, the distance of the first color pixel electrode 141 beyond the first opening 151, the distance of the second color pixel electrode 142 beyond the second opening 152, and the distance of the third color pixel electrode 143 beyond the third opening 153 are substantially equal. In other words, the shortest distance between the edge of the first color pixel electrode 141 and the edge of the first opening 151, the shortest distance between the edge of the second color pixel electrode 142 and the edge of the second opening 152, and the shortest distance between the edge of the third color pixel electrode 143 and the edge of the third opening 153 are substantially equal.

[0125] Fig.11 FIG. 1 is a schematic diagram of another array substrate provided by an embodiment of the present disclosure. Fig.11As shown, in each sub-pixel group 120, a first line CL1 between the centers of two first color sub-pixels 121 intersects with a second line CL2 between the centers of the second color sub-pixel 122 and the centers of the third color sub-pixel 123, and a length L1 of an orthographic projection of a third line CL3 between the centers of a first color sub-pixel 121 and the centers of the second color sub-pixel 122 on the second line CL2 is different from a length L2 of an orthographic projection of a fourth line CL4 between the centers of the same first color sub-pixel 121 and the centers of the third color sub-pixel 123 on the second line CL2. Therefore, when the array substrate is used to display a vertical line extending along the extension direction of the first connection line CL1, and the first color sub-pixel 121 and the third color sub-pixel 123 are colors that are sensitive to the human eye, the first color sub-pixel 121 can be set closer to the third color sub-pixel 123. Since the first color sub-pixel 121 is closer to the third color sub-pixel 123, the "fluctuation" of the vertical line seen by the human eye is weaker, thereby reducing or even eliminating the granularity of the displayed image and making the lines of the displayed image more continuous and natural.

[0126] In some examples, such as Fig.11 As shown, the length of the positive projection of the third line CL3 between the center of a first color sub-pixel 121 and the center of the second color sub-pixel 122 on the second line CL2 is greater than the length of the positive projection of the fourth line CL4 between the center of the same first color sub-pixel 121 and the center of the third color sub-pixel 123 on the second line CL2.

[0127] In some examples, such as Fig.11 As shown, in each sub-pixel group 120, no other sub-pixels are set between the first color sub-pixel 121 and the second color sub-pixel 122 in the direction of the third line, and no other sub-pixels are set between the first color sub-pixel 121 and the third color sub-pixel 123 in the direction of the fourth line.

[0128] In some examples, such as Fig.11 As shown, the array substrate 100 also includes: a sub-pixel interval 170, which is arranged between two adjacent sub-pixels, and the sub-pixel is any one of the first color sub-pixel 121, the second color sub-pixel 122 and the third color sub-pixel 123; each sub-pixel group 120 includes four sub-pixels separated by the sub-pixel interval 170.

[0129] In some examples, such as Fig.11As shown, a plurality of sub-pixel groups 120 are arranged along a first direction to form a plurality of sub-pixel group rows 131, and are arranged along a second direction intersecting the first direction to form a plurality of sub-pixel group columns 132, and two adjacent sub-pixel group columns 132 are staggered. In the sub-pixel column 132, two adjacent sub-pixel groups 120 include a first sub-pixel group 1201 and a second sub-pixel group 1202, and the ratio of the distance between the vertex of the first color sub-pixel 121 in the first sub-pixel group 1201 away from the second sub-pixel group 1202 and the vertex of the first color sub-pixel 121 in the second sub-pixel group 1202 away from the first sub-pixel group 1201 to the size of the second color sub-pixel 122 in the extension direction of the first connecting line is 0.8-1.2; that is, thus, the ratio of the distance between the vertices of the two first color sub-pixels closest to each other in the first sub-pixel group and the second sub-pixel group and the size of the second color sub-pixel in the extension direction of the first connecting line is 0.8-1.2, which can make the pixel arrangement on the array substrate more uniform.

[0130] In some examples, the distance between the first color sub-pixel 121 in the first sub-pixel group 1201 and the vertex of the second sub-pixel group 1202 and the vertex of the first color sub-pixel 121 in the second sub-pixel group 1202 and the vertex of the first color sub-pixel 121 in the first sub-pixel group 1201 is approximately equal to the size of the second color sub-pixel 122 in the extension direction of the first line. For example, the ratio of the distance between the first color sub-pixel 121 in the first sub-pixel group 1201 and the vertex of the second sub-pixel group 1202 and the vertex of the first color sub-pixel 121 in the second sub-pixel group 1202 and the size of the second color sub-pixel 122 in the extension direction of the first line is 0.9-1.1, thereby making the sub-pixel arrangement on the array substrate more uniform and allowing the third color sub-pixels to form regular hexagons.

[0131] In some examples, the ratio of the size of the shape of the first color sub-pixel 121 in the extending direction of the first line CL1 to the size of the shape of the first color sub-pixel 121 in the extending direction of the second line CL2 is in a range of 1.6-2.8.

[0132] For example, the ratio of the size of the first color sub-pixel 121 in the extending direction of the first line CL1 to the size of the first color sub-pixel 121 in the extending direction of the second line CL2 is in a range of 1.8-2.6, such as 2.2.

[0133] In some examples, the ratio of the size of the second color sub-pixel 122 in the extending direction of the first line CL1 to the size of the second color sub-pixel 122 in the extending direction of the second line CL2 is in a range of 4.3-6.7.

[0134] For example, the ratio of the size of the second color sub-pixel 122 in the extending direction of the first line CL1 to the size of the second color sub-pixel 122 in the extending direction of the second line CL2 is in a range of 4.5-6.5, for example, 5.5.

[0135] In some examples, the ratio of the size of the shape of the third color sub-pixel 123 in the extending direction of the first line CL1 to the size of the shape of the third color sub-pixel 123 in the extending direction of the second line CL2 is in a range of 0.4-0.76.

[0136] For example, the ratio of the size of the third color sub-pixel 123 in the extending direction of the first line CL1 to the size of the third color sub-pixel 123 in the extending direction of the second line CL2 is in a range of 0.5-0.66, such as 0.58.

[0137] In some examples, in each subpixel group 120, the orthographic projection of the second color subpixel 122 on the first line CL1 overlaps with the orthographic projection of the first color subpixel 121 on the first line CL1, and the orthographic projection of the third color subpixel 123 on the first line CL1 does not overlap with the orthographic projection of the first color subpixel 121 on the first line CL1.

[0138] In some examples, in each sub-pixel group 120 , the orthographic projection of the first color sub-pixel 121 on the second line CL2 overlaps with the orthographic projection 123 of the third color sub-pixel on the second line CL2 .

[0139] In some examples, such as Fig.11 As shown, the array substrate 100 further includes a plurality of pixel driving circuits 180, and the plurality of pixel driving circuits 180 are arranged in a one-to-one correspondence with the plurality of sub-pixels. Fig.11 As shown, one second color sub-pixel 122, one first color sub-pixel 121, one third color sub-pixel 123 in a sub-pixel group 120 and one first color sub-pixel 121 in a sub-pixel group 120 adjacent in the first direction may be arranged in one-to-one correspondence with four pixel driving circuits 180 arranged sequentially in the first direction. For example, the pixel electrodes in the sub-pixels may be electrically connected to the corresponding pixel driving circuits through vias, and the vias corresponding to the above four pixel driving circuits may be located substantially on the same straight line.

[0140] Fig.12 Schematic diagram of a display device provided by an embodiment of the present disclosure. Fig.12As shown, the display device 500 includes the above array substrate 100. Since the array substrate can reduce or even eliminate the graininess of the display image and make the lines of the display image more continuous and natural, the display device has a higher display quality. In addition, the display device can also achieve a higher pixel resolution with a relatively small number of sub-pixels.

[0141] For example, in some examples, the display device may be any product or component with a display function, such as a smart phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or the like.
