[0059] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure.

The terms “first”, “second” and similar words used in the present disclosure do not represent any order, number or importance, but are only used to distinguish different components. The terms “include” or “contain” and similar words mean that the elements or objects before the words cover the elements or objects listed after the words and their equivalents, and do not exclude other elements or objects.

[0061] Embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes a plurality of sub-pixels. The plurality of sub-pixels includes a plurality of first sub-pixels, a plurality of second sub-pixels, and a plurality of third sub-pixels; the plurality of first sub-pixels and the plurality of third sub-pixels are alternately arranged along a row direction and a column direction to form a plurality of first pixel rows and a plurality of first pixel columns, the plurality of second sub-pixels are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows and a plurality of second pixel columns, the plurality of first pixel rows and the plurality of second pixel rows are alternately arranged along the column direction, and the plurality of first pixel columns and the plurality of second pixel columns are alternately arranged along the row direction; the center of an adjacent one of the first sub-pixels and the third sub-pixels in the same first pixel row and the center of an adjacent one of the first sub-pixels and the third sub-pixels in the adjacent first pixel row and adjacent to the adjacent one of the first sub-pixels and the third sub-pixels along the column direction are four vertices of a virtual quadrilateral, and one second sub-pixel is arranged in the virtual quadrilateral.

[0062] The display substrate and the display device provided by the embodiments of the present disclosure are described below with reference to the drawings.

[0063] Figure 1 A partial structure schematic diagram of the display substrate provided by the embodiments of the present disclosure is shown. As shown in Figure 1 , the display substrate includes a plurality of sub-pixels 100. As shown in Figure 1 , the plurality of sub-pixels 100 includes a plurality of first sub-pixels 10, a plurality of second sub-pixels 20, and a plurality of third sub-pixels 30. The plurality of first sub-pixels 10 and the plurality of third sub-pixels 30 are alternately arranged along a row direction (as shown in Figure 1The first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the row direction (e.g., the X direction as shown) to form a first pixel row 01, and the second sub-pixels 20 are arranged along the row direction to form a second pixel row 02. The first pixel row 01 and the second pixel row 02 are arranged along a column direction (e.g., the Y direction as shown) which is perpendicular to the row direction. Figure 1 The first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the column direction (e.g., the Y direction as shown), and the second sub-pixels 20 are arranged along the row direction.

[0064] For example, as shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the row direction and the column direction to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04. The row direction and the column direction are perpendicular to each other. The row direction and the column direction can be interchanged. Figure 1 For example, as shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the row direction and the column direction to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04. The row direction and the column direction are perpendicular to each other. The row direction and the column direction can be interchanged.

[0065] Figure 1 For example, as shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the row direction and the column direction to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04. The row direction and the column direction are perpendicular to each other. The row direction and the column direction can be interchanged.

[0066] For example, the center of the sub-pixel can be the geometric center of the sub-pixel, or the intersection of the perpendicular bisectors of the edges of the sub-pixel, or a point in the sub-pixel which is equidistant to the edges of the sub-pixel. Of course, the center of the sub-pixel can be allowed to have a certain error. For example, the center of the sub-pixel can be any point within a range of 3 μm from the geometric center of the sub-pixel.

[0067] For example, as shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 are arranged alternately along the row direction and the column direction to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04. The row direction and the column direction are perpendicular to each other. The row direction and the column direction can be interchanged. Figure 1 ​As shown, the display substrate includes multiple repeating units A arranged in an array. Each repeating unit A includes two rows and four columns of sub-pixels, that is, each repeating unit A includes one first sub-pixel 10, one third sub-pixel 30, and two second sub-pixels 20. The first sub-pixel 10 and the third sub-pixel 30 are shared sub-pixels. Through a virtual algorithm, four sub-pixels can achieve the display of two virtual pixel units. For example, in the same row of repeating units, the first sub-pixel 10 in the second repeating unit, the third sub-pixel 30 in the first repeating unit, and the second sub-pixel 20 in the first repeating unit that is close to the second repeating unit form a virtual pixel unit. At the same time, the first sub-pixel 10 in the second repeating unit also forms a virtual pixel unit with the third sub-pixel 30 in the same repeating unit and the second sub-pixel 20 in the same repeating unit that is close to the first repeating unit. In addition, the third sub-pixel 30 in the second repeating unit also forms a virtual pixel unit with another second sub-pixel 20 in the same repeating unit and the first sub-pixel 10 in the third repeating unit, thereby effectively improving the resolution of the display substrate.

[0068] like Figure 1 As shown, when adjacent corners are connected by straight edges, each sub-pixel 100 includes a light-emitting area 110. In at least one of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30, the apex corner of the light-emitting area includes a first corner 111 and a second corner 112 disposed opposite to each other. The distance from the intersection of the extensions of the two straight edges constituting the first corner 111 to the center of the sub-pixel is different from the distance from the intersection of the two straight edges constituting the second corner 112 or their extensions to the center of the sub-pixel.

[0069] For example, Figure 2 for Figure 1 A schematic enlarged view of a sub-pixel is shown below, as follows: Figure 2 As shown, the distance from the intersection of the extensions of the two straight edges L1 and L2 constituting the first corner 111 to the center O of the sub-pixel is different from the distance from the intersection of the two straight edges L3 and L4 constituting the second corner 112 to the center O of the sub-pixel.

[0070] In this embodiment, a sub-pixel refers to a light-emitting device structure, and the first sub-pixel, the second sub-pixel, and the third sub-pixel are sub-pixels that emit light of different colors. This embodiment uses a red sub-pixel as an example, a green sub-pixel as the first sub-pixel, and a blue sub-pixel as the second sub-pixel. However, using a red sub-pixel as the first sub-pixel, a green sub-pixel as the second sub-pixel, and a blue sub-pixel as the third sub-pixel does not constitute a limitation on the scope of protection of this embodiment.

[0071] For example, the first sub-pixel 10 and the third sub-pixel 30 are common sub-pixels, and according to the light emission spectrum of the two, the area of each of the two is greater than the area of the second sub-pixel 20. In the display substrate provided by the embodiment of the present disclosure, by adjusting the shape of part of the sub-pixels, the distance from the intersection of the extensions of the two straight sides constituting the first corner to the center of the sub-pixel is different from the distance from the intersection of the extensions of the two straight sides constituting the second corner to the center of the sub-pixel in at least one of the first sub-pixel, the second sub-pixel, and the third sub-pixel, so as to adjust the actual brightness center of each virtual pixel unit, so that the actual brightness centers in the display substrate are more uniformly distributed.

[0072] As shown in FIG. 1, at least one of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 includes a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004, and the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 is different in different type sub-pixels. For example, the positions of the first corner 111 are different in different type sub-pixels. For example, the orientations of the first corner 111 are different in different type sub-pixels. Figure 1 For example, the shapes of the type sub-pixels are the same, or the areas of the type sub-pixels are the same. For example, the shapes and the areas of the type sub-pixels are the same. For example, the number of different type sub-pixels is substantially the same. For example, the number ratio of any two types of sub-pixels among the first type sub-pixel, the second type sub-pixel, the third type sub-pixel, and the fourth type sub-pixel is 0.8-1.2. For example, the number ratio of the first type sub-pixel and the second type sub-pixel is 0.8-1.2, and the number ratio of the third type sub-pixel and the fourth type sub-pixel is 0.8-1.2.

[0073] As shown in FIG. 1, the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 in the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004 is the first direction D1, the second direction D2, the third direction D3, and the fourth direction D4, respectively. For example, in the light emission area of the first type sub-pixel 1001, the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 is the first direction D1; in the light emission area of the second type sub-pixel 1002, the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 is the second direction D2; in the light emission area of the third type sub-pixel 1003, the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 is the third direction D3; and in the light emission area of the fourth type sub-pixel 1004, the direction in which the vertex of the first corner 111 points to the vertex of the second corner 112 is the fourth direction D4.

[0074] Figure 1 ​​

[0075] As shown in Figure 1 , the first direction D1 and the second direction D2 are opposite, and the third direction D3 and the fourth direction D4 are opposite.

[0076] The display substrate provided by the embodiments of the present disclosure has four different types of sub-pixels, which is beneficial to improve the color deviation problem of the display substrate when displaying.

[0077] In addition, in general display substrates, the shapes of the four corners included in the opening area of each different color sub-pixel are the same, and relative to such display substrates, the display substrate provided by the embodiments of the present disclosure has the four different types of sub-pixels, which is beneficial to reduce the grainy feeling when the display substrate displays.

[0078] For example, as shown in Figure 1 , at least one of the first sub-pixel 10, the second sub-pixel 20 and the third sub-pixel 30 further includes a third corner portion 113 and a fourth corner portion 114 arranged oppositely, and the line L connecting the vertex of the third corner portion 113 and the vertex of the fourth corner portion 114 divides the light-emitting area into two parts, the shapes of the two parts are different, and the area of the part where the first corner portion 111 is located is smaller than the area of the part where the second corner portion 112 is located. The line L connecting the vertex of the third corner portion 113 and the vertex of the fourth corner portion 114 divides the light-emitting area into a first part and a second part, the first corner portion is a corner portion in the first part, and the second corner portion is a corner portion in the second part, then the part where the first corner portion is located refers to the first part, and the part where the second corner portion is located refers to the second part.

[0079] For example, the ratio of the area of the part where the first corner portion 111 is located to the area of the part where the second corner portion 112 is located can be 0.1-0.95. For example, the ratio of the area of the part where the first corner portion 111 is located to the area of the part where the second corner portion 112 is located can be 0.3-0.8. For example, the ratio of the area of the part where the first corner portion 111 is located to the area of the part where the second corner portion 112 is located can be 0.4-0.7.

[0080] In general display substrates, the shapes and areas of the two parts where the two corners opposite to each other in each sub-pixel are located are the same, and relative to such display substrates, the display substrate provided by the present disclosure can effectively improve the light transmittance of the display substrate when the display substrate is applied to a display device with an under-screen fingerprint function or an under-screen camera function by reducing the area of the part where the first corner portion is located.

[0081] For example, Figure 2 and Figure 3 are schematic enlarged views of the third type of sub-pixel in different examples. As shown in Figure 2 and Figure 3As shown, the above-mentioned top corner can be an included angle between two lines, for example, the second corner 112, the third corner 113 and the fourth corner 114, for example, the three corners can all be right angles or acute angles. For example, the intersection of the two lines is the vertex of the corner, at this time, the corner can be a range of x microns along the contour from the vertex, the value of x can be 2-7 microns. For example, Figure 2 As shown, the above-mentioned top corner can also be a curved line formed by the intersection of the two edges of a certain top corner extending to the vertex to make the top corner a round chamfer, for example, the first corner 111 includes a round chamfer, the vertex of the corner can be the intersection of the extensions of the two edges used to form the above-mentioned round chamfer and the intersection P of the line connecting the vertex of the top corner opposite the round chamfer and the round chamfer. At this time, the corner can be a range of x microns along the contour from the vertex P, the value of x can be 2-7 microns. When the first corner is a round chamfer and the second corner is a right angle or an acute angle, the distance from the intersection of the extensions of the two straight edges constituting the first corner to the center of the sub-pixel is less than the distance from the intersection of the extensions of the two straight edges constituting the second corner to the center of the sub-pixel.

[0082] The above-mentioned "round chamfer" is a top corner formed by a curved line, which can be a circular arc or an irregular curve, for example, a curve taken from an ellipse, a wavy line, etc. The embodiments of the present disclosure schematically show that the curve has a shape that is convex outward with respect to the center of the sub-pixel, but are not limited thereto, and can also have a shape that is concave inward with respect to the center of the sub-pixel. For example, when the curve is a circular arc, the range of the central angle of the circular arc can be 10°-150°. For example, the range of the central angle of the circular arc can be 60°-120°. For example, the range of the central angle of the circular arc can be 90°. For example, the length of the curve of the round chamfer included by the first corner 111 can be 10-60 microns.

[0083] As shown, Figure 3 The above-mentioned top corner can also be a line segment formed by the intersection of the two edges of a certain top corner extending to the vertex to make the top corner a flat chamfer, for example, the first corner 111 includes a flat chamfer, the vertex of the corner can be the intersection of the two edges used to form the above-mentioned flat chamfer and the intersection P of the line connecting the vertex of the top corner opposite the flat chamfer and the flat chamfer.

[0084] For example, Figure 4A And Figure 4B are schematic enlarged views of third type sub-pixels in different examples. As shown, Figure 4AAs shown, the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 all include rounded chamfers, and the radius of curvature of the rounded chamfer of the first corner 111 is greater than the radius of curvature of the rounded chamfer of the second corner 112. For example, when all four corners include rounded chamfers, the vertex of each corner can be the intersection of the line connecting the intersection of the extensions of the two sides used to form the rounded chamfer and the intersection of the line connecting the intersection of the extensions of the two sides used to form the rounded chamfer opposite to the rounded chamfer with the rounded chamfer itself. In this case, each corner can be a range of x micrometers along the contour centered on the vertex of the corner, where the value of x can be 2 to 7 micrometers.

[0085] For example, the radius of curvature of the first corner portion 111 can be 10% to 70% of the length of the straight edge forming the rounded chamfer. For example, the radius of curvature of the first corner portion 111 can be 20% to 50% of the length of the straight edge forming the rounded chamfer.

[0086] For example, the length of the line connecting the vertices of the second corner 112 and the third corner 113 can be 40 micrometers. For example, the radius of curvature of the first corner 111 can be 5 to 20 micrometers. For example, the radius of curvature of the second corner 112 is less than 5 micrometers.

[0087] For example, the radius of curvature of the rounded chamfer of the first corner 111 is greater than the radius of curvature of the rounded chamfers of the other three corners.

[0088] For example, such as Figure 4B As shown, with Figure 4A The difference in the third type of sub-pixel shown is that the edges connecting adjacent corners are curved rather than straight. The definitions of each corner and the vertices within the corners in this example are... Figure 4A The same applies to the example shown. Figure 4B In the example shown, when adjacent corners are connected by curved edges, each sub-pixel 100 includes a light-emitting area 110. In at least one of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30, the apex corner of the light-emitting area includes a first corner 111 and a second corner 112 disposed opposite to each other. The distance from the intersection of the tangents of the two sides constituting the first corner 111 to the center of the sub-pixel is different from the distance from the intersection of the tangents of the two sides constituting the second corner 112 to the center of the sub-pixel.

[0089] For example, Figure 5 This is a schematic diagram of the planar structure of the pixel-defining layer that defines the display substrate. (See diagram below.) Figure 1 and Figure 5 As shown, the shape of the light-emitting area of ​​each sub-pixel 100 is defined by the opening in the pixel limiting layer 200, so the shape of the light-emitting area of ​​each sub-pixel 100 is approximately the same as the shape of the opening in the pixel limiting layer 200.

[0090] For example, such as Figure 1 andFigure 5 As shown, the pixel defining layer 200 includes a plurality of first openings 201, a plurality of second openings 202, and a plurality of third openings 203. The first openings 201 define the first light emitting areas 110-1 of the first sub-pixels 10, the second openings 202 define the second light emitting areas 110-2 of the second sub-pixels 20, and the third openings 203 define the third light emitting areas 110-3 of the third sub-pixels 30.

[0091] For example, each sub-pixel 100 includes a first electrode, a light emitting layer, and a second electrode which are arranged in a stack, and when the light emitting layer is formed in the opening in the pixel defining layer 200, the first electrode and the second electrode on both sides of the light emitting layer can drive the light emitting layer in the opening of the pixel defining layer 200 to emit light. For example, at least one of the light emitting layer and the first electrode and the light emitting layer and the second electrode further includes a functional layer. For example, the functional layer includes any one or more of a hole injection layer, a hole transport layer, an electron transport layer, a hole blocking layer, an electron blocking layer, an electron injection layer, an auxiliary light emitting layer, an interface improvement layer, an anti-reflection layer, etc.

[0092] The embodiments of the present disclosure schematically show that the shape of the opening of the pixel defining layer is a quadrilateral, and the shape of the light emitting area of each sub-pixel is also a quadrilateral, which includes four vertexes. However, it is not limited thereto, and the shape of the light emitting area of each sub-pixel can also be a triangle, a pentagon, or a hexagon, etc., and the number of vertexes included in the light emitting area also changes accordingly.

[0093] For example, as shown in FIG. 1A, the shape of the first corner 111 and the shape of the fourth corner 114 are substantially the same. For example, the shape of the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 are substantially the same. The “the shape of the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 are substantially the same” means, for example, that the angles of the three are the same, the outlines are the same, the sizes are the same, the curvatures of the rounded corners are the same, etc. Figure 1 For example, as shown in FIG. 1A, the shape of the first corner 111 and the shape of the fourth corner 114 are substantially the same. For example, the shape of the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 are substantially the same. The “the shape of the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 are substantially the same” means, for example, that the angles of the three are the same, the outlines are the same, the sizes are the same, the curvatures of the rounded corners are the same, etc.

[0094] Figure 1 For example, as shown in FIG. 1A, the shape and size of the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004 are substantially the same, and the three types of sub-pixels can have the same orientation of the first corner as the fourth type sub-pixel after being rotated by a certain angle. Here, the orientation of the first corner can refer to the direction in which the vertex of the first corner points to the vertex of the second corner.

[0095] For example, as shown in FIG. 1A, the shape and size of the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004 are substantially the same, and the three types of sub-pixels can have the same orientation of the first corner as the fourth type sub-pixel after being rotated by a certain angle. Here, the orientation of the first corner can refer to the direction in which the vertex of the first corner points to the vertex of the second corner. Figure 1 ​As shown, the distance d1 between the vertex of the first corner 111 and the line L is less than the distance d2 between the vertex of the second corner 112 and the line L. For example, the ratio d1 / d2 of the distance d1 between the vertex of the first corner 111 and the line L to the distance d2 between the vertex of the second corner 112 and the line L can range from 0.1 to 0.9. For example, the ratio d1 / d2 can range from 0.2 to 0.8. For example, the ratio d1 / d2 can range from 0.4 to 0.6. For example, the ratio of d1 to d2 can range from 0.7 to 0.9.

[0096] For example, as shown in FIG. 1A, the first corner 111 and the second corner 112 are located on the same side of the line L. Figure 1 As shown, the length of the line between the vertex of the first corner 111 and the vertex of the second corner 112 can be a (i.e., the sum of the distance d1 and the distance d2 described above), and the length of the line L between the vertex of the third corner 113 and the vertex of the fourth corner 114 can be b, and the ratio of a to b can range from 0.6 to 0.9. For example, the ratio of a to b can range from 0.7 to 0.8.

[0097] For example, as shown in FIG. 1A, the first corner 111 and the second corner 112 are located on the same side of the line L. Figure 1 As shown, the length of the line between the vertex of the first corner 111 and the vertex of the second corner 112 can be a (i.e., the sum of the distance d1 and the distance d2 described above), and the length of the line L between the vertex of the third corner 113 and the vertex of the fourth corner 114 can be b, and the ratio of a to b can range from 0.6 to 0.9. For example, the ratio of a to b can range from 0.7 to 0.8. Figure 5 As shown, the length of the line between the vertex of the first corner 111 and the vertex of the second corner 112 can be a (i.e., the sum of the distance d1 and the distance d2 described above), and the length of the line L between the vertex of the third corner 113 and the vertex of the fourth corner 114 can be b, and the ratio of a to b can range from 0.6 to 0.9. For example, the ratio of a to b can range from 0.7 to 0.8.

[0098] For example, the light-emitting layer of the first sub-pixel 10 and the third sub-pixel 30 adjacent to each other can overlap or not overlap on the pixel definition layer 200. For example, the light-emitting layer of the first sub-pixel 10 and the second sub-pixel 20 adjacent to each other can overlap or not overlap on the pixel definition layer 200. For example, the light-emitting layer of the second sub-pixel 20 and the third sub-pixel 30 adjacent to each other can overlap or not overlap on the pixel definition layer 200. For example, in the direction parallel to the XY plane, the shortest distance between the vertex of the first corner 111 and the light-emitting layer boundary is less than the shortest distance between the vertex of the second corner 112 and the light-emitting layer boundary. For example, the shortest distance between the vertex of the first corner 111 and the light-emitting layer boundary is less than the shortest distance between the vertex of the other three corners and the light-emitting layer boundary.

[0099] For example, as shown in FIG. 1A, the first corner 111 and the second corner 112 are located on the same side of the line L. Figure 1 As shown, one of the first direction D1 and the third direction D3 is parallel to the row direction, and the other is parallel to the column direction. Figure 1The third direction D3 and the fourth direction D4 are parallel to the row direction, and the first direction D1 and the second direction D2 are parallel to the column direction, but the positional relationship between the first direction and the third direction can be interchanged.

[0100] For example, as shown in FIG. 1, the direction indicated by the arrow of the X direction is to the right, and the direction indicated by the arrow of the Y direction is upward. In this case, the first corner 111 of the first type sub-pixel 1001 is located at the lower side of the sub-pixel, the first corner 111 of the second type sub-pixel 1002 is located at the upper side of the sub-pixel, the first corner 111 of the third type sub-pixel 1003 is located at the left side of the sub-pixel, and the first corner 111 of the fourth type sub-pixel 1004 is located at the right side of the sub-pixel. Figure 1 For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3.

[0101] Figure 1 For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3.

[0102] In the embodiments of the present disclosure, the direction in which the vertex of the first corner of each type of sub-pixel points to the vertex of the second corner is set to be parallel to the row direction or the column direction, which can improve the color deviation problem of the entire display substrate during display while ensuring the aperture ratio of each sub-pixel.

[0103] For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3. Figure 1 For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3.

[0104] Figure 1 For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3.

[0105] For example, as shown in FIG. 1, the angle between the row direction and the column direction is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 80°-100°. For example, the angle between the first direction D1 and the third direction D3 is 85°-95°. For example, the angle between the first direction D1 and the third direction D3 is 90°, that is, the first direction D1 is perpendicular to the third direction D3. Figure 1 ​​In an example of the display substrate shown, the plurality of third sub-pixels 30 (i.e., blue sub-pixels) of each first pixel group 010 includes a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004, and the four first sub-pixels 10 do not include the four types of sub-pixels, i.e., the shape, size, and arrangement of the four first sub-pixels 10 in each first pixel group 010 are the same.

[0106] For example, Figure 1 In an example of the display substrate shown, the first type sub-pixel 1001 and the second type sub-pixel 1002 of each first pixel group 010 are arranged adjacent to each other, and / or the third type sub-pixel 1003 and the fourth type sub-pixel 1004 are arranged adjacent to each other.

[0107] For example, the arrangement order of different types of sub-pixels in each first pixel group 010 can be: the second type sub-pixel 1002, the first type sub-pixel 1001, the third type sub-pixel 1003, and the fourth type sub-pixel 1004; the first type sub-pixel 1001, the third type sub-pixel 1003, the fourth type sub-pixel 1004, and the second type sub-pixel 1002; the third type sub-pixel 1003, the fourth type sub-pixel 1004, the second type sub-pixel 1002, and the first type sub-pixel 1001; or the fourth type sub-pixel 1004, the second type sub-pixel 1002, the first type sub-pixel 1001, and the third type sub-pixel 1003.

[0108] For example, as shown in Figure 1 As shown, two first pixel groups 010 located in adjacent first pixel rows 01 and adjacent to each other are staggered.

[0109] In the display substrate provided by the embodiments of the present disclosure, by arranging a plurality of first pixel groups including the four types of sub-pixels in the row direction at least at the non-edge position of the display area, the color deviation problem of the display substrate when performing detailed display such as horizontal lines (e.g., only including one of the plurality of first pixel rows) is improved. Of course, the embodiments of the present disclosure are not limited to arranging the four types of sub-pixels in the row direction, and the row direction and the column direction can be interchanged. Therefore, in the display substrate provided by the embodiments of the present disclosure, the four types of sub-pixels can also be arranged in the column direction at least at the non-edge position of the display area to improve the color deviation problem of the display substrate when performing detailed display such as vertical lines.

[0110] For example, as shown in Figure 1As shown, at least one first pixel column 03 includes a plurality of second pixel groups 020, each second pixel group 020 including eight sub-pixels 100, and each second pixel group 020 including a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004. For example, a display substrate includes at least one display area, and each first pixel column 03 located at a non-edge position of the display area includes a plurality of second pixel groups 020. For example, each first pixel column 03 in a display substrate includes a plurality of second pixel groups 020.

[0111] For example, such as Figure 1 As shown, each second pixel group 020 includes four first sub-pixels 10 and four third sub-pixels 30.

[0112] For example, Figure 1 In one example of the display substrate shown, the plurality of third sub-pixels 30 (i.e. blue sub-pixels) in each second pixel group 020 include a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004, while the four first sub-pixels 10 do not include the above four types of sub-pixels. That is, the shape, size and arrangement of the four first sub-pixels 10 in each second pixel group 020 are all the same.

[0113] For example, such as Figure 1 As shown, in each second pixel group 020, the first type sub-pixel 1001 and the second type sub-pixel 1002 are arranged adjacent to each other, and / or the third type sub-pixel 1003 and the fourth type sub-pixel 1004 are arranged adjacent to each other.

[0114] For example, the arrangement order of different types of sub-pixels in each first pixel group 020 can be: first type sub-pixel 1001, third type sub-pixel 1003, fourth type sub-pixel 1004 and second type sub-pixel 1002; third type sub-pixel 1003, fourth type sub-pixel 1004, second type sub-pixel 1002 and first type sub-pixel 1001; fourth type sub-pixel 1004, second type sub-pixel 1002, first type sub-pixel 1001 and third type sub-pixel 1003; or second type sub-pixel 1002, first type sub-pixel 1001, third type sub-pixel 1003 and fourth type sub-pixel 1004.

[0115] In the display substrate provided in this disclosure, by setting a first pixel group and a second pixel group including the above four different types of sub-pixels in the row direction and column direction at least at the non-edge position of the display area, it is beneficial to improve the color shift problem that occurs when the display substrate displays details such as horizontal and vertical lines (e.g., only one of multiple first pixel columns).

[0116] For example, such asFigure 1 As shown, along the extension direction of the first diagonal 1011 of the virtual quadrilateral 101, the first sub-pixel 10 and the second sub-pixel 20 are arranged alternately, and along the extension direction of the second diagonal 1012 of the virtual quadrilateral 101, the third sub-pixel 30 and the second sub-pixel 20 are arranged alternately. For example, the extension direction of the first diagonal 1011 intersects both the row and column directions, and the extension direction of the second diagonal 1012 of the virtual quadrilateral 101 intersects both the row and column directions.

[0117] For example, such as Figure 1 As shown, the sub-pixels 100 arranged along the extension direction of one of the first diagonals 1011 and the second diagonal 1012 of the virtual quadrilateral 101 include a plurality of third pixel groups 030, each third pixel group 030 including eight sub-pixels 100, and each third pixel group 030 including a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0118] For example, Figure 1 In one example of the display substrate shown, each third pixel group 030 includes four third sub-pixels 30 and four second sub-pixels 20. The four third sub-pixels 30 in each third pixel group 030 can be respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004, while the four second sub-pixels 20 do not include the above four types of sub-pixels. That is, the shape, size and arrangement of the four second sub-pixels 20 in each third pixel group 030 are the same.

[0119] For example, such as Figure 1 As shown, in each third pixel group 030, the first type sub-pixel 1001 and the second type sub-pixel 1002 are arranged adjacent to each other, and / or the third type sub-pixel 1003 and the fourth type sub-pixel 1004 are arranged adjacent to each other.

[0120] For example, the arrangement order of different types of sub-pixels in each third pixel group 030 can be: fourth type sub-pixel 1004, second type sub-pixel 1002, first type sub-pixel 1001 and third type sub-pixel 1003; second type sub-pixel 1002, first type sub-pixel 1001 and third type sub-pixel 1003; first type sub-pixel 1001, third type sub-pixel 1003, fourth type sub-pixel 1004 and second type sub-pixel 1002; or third type sub-pixel 1003, fourth type sub-pixel 1004, second type sub-pixel 1002 and first type sub-pixel 1001.

[0121] In the display substrate provided in this embodiment, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, it is beneficial to improve the color shift problem that occurs when the display substrate displays details such as horizontal lines, vertical lines, and diagonal lines.

[0122] For example, such as Figure 5 As shown, the shape of the light-emitting area 110-1 of the first sub-pixel 10 includes multiple vertices, each with a roughly identical shape. The vertices of the third sub-pixel 30 are opposite to the vertices of the first sub-pixel 10. For example, if the light-emitting areas of both the first sub-pixel 10 and the third sub-pixel 30 are quadrilaterals, each including four vertices, then the four corners of each type of sub-pixel included in the third sub-pixel 30 are respectively opposite to the four vertices of the four first sub-pixels 10 surrounding the third sub-pixel 30.

[0123] For example, such as Figure 5 As shown, the shortest distance d3 between the first corner 111 of the third sub-pixel 30 and the apex corner of the first sub-pixel 10 is greater than the shortest distance d4 between the second corner 112 of the third sub-pixel 30 and the apex corner of the first sub-pixel 10. For example, as Figure 5 As shown, the shortest distance d4 between the other three corners of the third sub-pixel 30 (such as the second corner 112, the third corner 113, and the fourth corner 114) and the corresponding three vertices of the first sub-pixel 10 is approximately equal. For example, the ratio of d4 to d3 can range from 0.3 to 0.9. For example, the ratio of d4 to d3 can range from 0.4 to 0.8.

[0124] For example, such as Figure 1 and Figure 2 As shown, the third opening 203 of the third light-emitting area 110-3 forming the third sub-pixel 30 in the pixel limiting layer 200 has the same shape, size, and arrangement as the third light-emitting area 110-3. Therefore, the third opening 203 also has a first opening corner portion 211, a second opening corner portion 212, a third opening corner portion 213, and a fourth opening corner portion 214 that correspond one-to-one with the first corner portion 111, the second corner portion 112, the third corner portion 113, and the fourth corner portion 114 of the third light-emitting area 110-3. For example, as... Figure 4B As shown, the shortest distance d3' between the first opening corner 211 of the third opening 203 and the opening apex angle of the first opening 201 is greater than the shortest distance d4' between the second opening corner 212 of the third opening 203 and the opening apex angle of the first opening 201. For example, as Figure 3 As shown, the shortest distances between the other three opening corners of the third opening 203 (such as the second opening corner 212, the third opening corner 213, and the fourth opening corner 214) and the opening apex angle of the first opening 201 are approximately equal.

[0125] The third sub-pixel in the display substrate can be adjusted in shape and the distance between each corner of the third sub-pixel and each vertex of the first sub-pixel by adjusting the shape of the third opening of the pixel definition layer and the distance between each corner of the third opening and each vertex of the first opening.

[0126] For example, as shown in FIG. 1, the length of the first straight side L1 connecting the first corner 111 and the third corner 113 is equal to the length of the second straight side L2 connecting the first corner 111 and the fourth corner 114; the length of the third straight side L3 connecting the second corner 112 and the third corner 113 is equal to the length of the fourth straight side L4 connecting the second corner 112 and the fourth corner 114, and the length of the first straight side L1 is less than the length of the third straight side L3. Figure 4A

[0127] For example, as shown in FIG. 1, when the first corner 111 includes a round chamfer and the other three corners are acute angles or right angles, the first straight side L1 refers to a straight line connecting an end point of the curve constituting the round chamfer close to the third corner 113 and a vertex of the third corner 113, the second straight side L2 refers to a straight line connecting an end point of the curve constituting the round chamfer close to the fourth corner 114 and a vertex of the fourth corner 114, the third straight side L3 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the third corner 113, and the fourth straight side L4 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the fourth corner 114. Figure 5

[0128] The embodiments of the present disclosure are not limited to the straight side connecting adjacent corners, for example, it can also be a curved side as shown in FIG. 2, and the length of the side connecting adjacent corners can also refer to the length of the curved side, which refers to the part other than the end point of the round chamfer. Figure 1

[0129] For example, as shown in FIG. 3, when the first corner 111 includes a flat chamfer and the other three corners are acute angles or right angles, the first straight side L1 refers to a straight line connecting an end point of the line segment constituting the flat chamfer close to the third corner 113 and a vertex of the third corner 113, the second straight side L2 refers to a straight line connecting an end point of the line segment constituting the flat chamfer close to the fourth corner 114 and a vertex of the fourth corner 114, the third straight side L3 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the third corner 113, and the fourth straight side L4 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the fourth corner 114. Figure 1

[0130] For example, as shown in FIG. 4, when the first corner 111 includes a flat chamfer and the other three corners are acute angles or right angles, the first straight side L1 refers to a straight line connecting an end point of the line segment constituting the flat chamfer close to the third corner 113 and a vertex of the third corner 113, the second straight side L2 refers to a straight line connecting an end point of the line segment constituting the flat chamfer close to the fourth corner 114 and a vertex of the fourth corner 114, the third straight side L3 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the third corner 113, and the fourth straight side L4 refers to a straight line connecting a vertex of the second corner 112 and a vertex of the fourth corner 114. Figure 1 ​​​​As shown, when the first corner 111, the second corner 112, the third corner 113, and the fourth corner 114 are all rounded chamfers, the first straight side L1 refers to the straight line connecting the endpoint of the curve constituting the rounded chamfer of the first corner 111 near the third corner 113 and the endpoint of the curve constituting the rounded chamfer of the third corner 113 near the first corner 111. The second straight side L2 refers to the straight line connecting the endpoint of the curve constituting the rounded chamfer of the first corner 111 near the fourth corner 114 and the endpoint of the curve constituting the rounded chamfer of the fourth corner 114. The curve of the rounded chamfer is the straight line near the endpoint of the first corner 111. The third straight edge L3 refers to the straight line connecting the curve of the rounded chamfer constituting the second corner 112 near the endpoint of the third corner 113 and the curve of the rounded chamfer constituting the third corner 113 near the endpoint of the second corner 112. The fourth straight edge L4 refers to the straight line connecting the curve of the rounded chamfer constituting the second corner 112 near the endpoint of the fourth corner 114 and the curve of the rounded chamfer constituting the fourth corner 114 near the endpoint of the second corner 112.

[0131] In the display substrate provided in this embodiment, the position of the brightness center of the third sub-pixel can be adjusted by setting the lengths of the four sides of the light-emitting area of ​​the third sub-pixel.

[0132] For example, such as Figure 5 As shown, the length of the first straight edge L1' connecting the first opening corner 211 and the third opening corner 213 of the third opening 203 is equal to the length of the second straight edge L2' connecting the first opening corner 211 and the fourth opening corner 214 of the third opening 203. For example, the length of the third straight edge L3' connecting the second opening corner 212 and the third opening corner 213 of the third opening 203 is equal to the length of the fourth straight edge L4' connecting the second opening corner 212 and the fourth opening corner 214 of the third opening 203, and the length of the first straight edge L1' is less than the length of the third straight edge L3'. The definition of each straight edge of the third opening is the same as the definition of each straight edge of the light-emitting area of ​​the third sub-pixel, and will not be repeated here.

[0133] For example, such as Figure 5 As shown, the light-emitting area 110-2 of the second sub-pixel 20 includes a fifth straight edge L5 that is arranged opposite to each other and parallel to each other, and a sixth straight edge L6 that is arranged opposite to each other and parallel to each other. The fifth straight edge L5 is parallel to the straight edge of the light-emitting area 110-3 of the third sub-pixel 20, and the sixth straight edge L6 is parallel to the straight edge of the light-emitting area 110-3 of the first sub-pixel 10.

[0134] For example, such as Figure 1As shown, the shape of the light-emitting area of ​​each second sub-pixel 20 can be a rectangle or a rounded rectangle. The rectangles mentioned above include standard rectangles and approximate rectangles. A standard rectangle is defined as a rectangle where the included angle between two adjacent sides is 90°, and an approximate rectangle is defined as a rectangle where the included angle between two adjacent sides is close to 90°, for example, 88° to 92°.

[0135] For example, when the shape of each second sub-pixel 20 is a rectangle, the aforementioned fifth and sixth straight edges refer to two adjacent edges that directly intersect. A rounded rectangle refers to a rectangle in which at least one of its four corners is rounded; that is, the adjacent edges of the rectangle are connected by shorter arcs to form rounded corners. For example, the four sides of a rounded rectangle can intersect each other to form a rectangle. For example, when the shape of each second sub-pixel 20 is a rounded rectangle, the aforementioned fifth and sixth straight edges refer to two adjacent edges that connect the two ends of the curve forming the rounded corner.

[0136] For example, such as Figure 1 As shown, the ratio of the length of the first straight edge L1 of the third sub-pixel 30 to the length of the fifth straight edge L5 of the second sub-pixel 20 ranges from 0.7 to 1.5, and the length of the third straight edge L3 of the third sub-pixel 30 is greater than the length of the fifth straight edge L5 of the second sub-pixel 20.

[0137] For example, such as Figure 5 As shown, the second opening 202 forming the second sub-pixel 20 in the pixel limiting layer 200 includes a fifth opening straight edge L5' that is arranged opposite to each other and parallel to each other, and a sixth opening straight edge L6' that is arranged opposite to each other and parallel to each other. The fifth opening straight edge L5' is parallel to the opening straight edge of the third opening 203, and the sixth opening straight edge L6' is parallel to the opening straight edge of the first opening 201.

[0138] For example, such as Figure 6 As shown, the length of the first opening straight edge L1' of the third opening 203 is not greater than the length of the fifth opening straight edge L5' of the second opening 202, and the length of the third opening straight edge L3' of the third opening 203 is greater than the length of the fifth opening straight edge L5' of the second opening 202.

[0139] For example, such as Figure 6 As shown, the third sub-pixels 30 arranged along the other extension direction of the first diagonal 1011 and the second diagonal 1012 of the virtual quadrilateral 101 can be sub-pixels of the same type, for example, they can all be first type sub-pixels 1001, second type sub-pixels 1002, third type sub-pixels 1003 or fourth type sub-pixels 1004.

[0140] For example, such as Figure 5 As shown, the four third sub-pixels 30 surrounding each first sub-pixel 10 include at least two different types of sub-pixels. For example, as Figure 6As shown, the four third sub-pixels 30 surrounding each first sub-pixel 10 may include two different types of sub-pixels, or four different types of sub-pixels.

[0141] For example, Figure 5 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate provided according to another example of an embodiment of the present disclosure. Figure 6 The example shown is the same as Figure 6 The difference in the example shown is that the sub-pixels 100 arranged along the extension direction of one of the first diagonals 1011 and the second diagonal 1012 of the virtual quadrilateral 101 include a plurality of third pixel groups 030, each third pixel group 030 including eight sub-pixels 100, and each third pixel group 030 including a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004; the sub-pixels 100 arranged along the other extension direction of the first diagonal 1011 and the second diagonal 1012 of the virtual quadrilateral 101 include a plurality of fourth pixel groups 040, each fourth pixel group 040 including four sub-pixels 100, and each fourth pixel group 040 including two types of sub-pixels among the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004.

[0142] For example, such as Figure 7 As shown, in this example, the arrangement order of the eight sub-pixels 100 included in each third pixel group 030 can be the same as... Figure 7 The arrangement order of the eight sub-pixels 100 included in each of the third pixel groups 030 shown may be the same or different; this example does not impose any restrictions on this.

[0143] In one example of an embodiment of this disclosure, each fourth pixel group 040 includes two third sub-pixels 30 and two second sub-pixels 20. The two third sub-pixels 30 in each fourth pixel group 040 can be any two of the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003 and the fourth type sub-pixel 1004, while the two second sub-pixels 20 do not include the above four types of sub-pixels. That is, the shape, size and arrangement of the two second sub-pixels 20 in each fourth pixel group 040 are the same.

[0144] For example, such as Figure 6 As shown, each fourth pixel group 040 includes a first type sub-pixel 1001 and a fourth type sub-pixel 1004, or includes a third type sub-pixel 1003 and a second type sub-pixel 1002.

[0145] In the display substrate provided in this embodiment, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, and setting a fourth pixel group including the above two different types of sub-pixels in another diagonal direction, the color shift problem that occurs when displaying details such as horizontal lines, vertical lines, and diagonal lines on the display substrate can be further improved.

[0146] For example, such as Figure 7 As shown, the four third sub-pixels 30 surrounding each first sub-pixel 10 are respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004.

[0147] In this embodiment of the disclosure, by setting the four third sub-pixels surrounding the first sub-pixel to include four different types of sub-pixels, it is beneficial to reduce color shift and uniformize the visual effect when displaying detailed images with a small number of sub-pixels.

[0148] For example, Figure 7 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate provided according to another example of an embodiment of the present disclosure. Figure 8 The example shown is the same as Figure 8 The difference in the examples shown lies in the arrangement order of the different types of subpixels within each pixel group. For example, as... Figure 1 As shown, in the first pixel group 010, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002; in the second pixel group 020, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002; in the third pixel group 030, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002.

[0149] For example, such as Figure 8 As shown, each fourth pixel group 040 includes a first type sub-pixel 1001 and a second type sub-pixel 1004, or includes a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0150] In the display substrate provided in this embodiment, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, and setting a fourth pixel group including the above two different types of sub-pixels in another diagonal direction, the color shift problem that occurs when displaying details such as horizontal lines, vertical lines, and diagonal lines on the display substrate can be further improved.

[0151] For example, Figure 9 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate according to another example of an embodiment of the present disclosure. Figure 9 The example shown is the same as Figure 7 The difference in the examples shown lies in the arrangement order of the different types of subpixels within each pixel group. For example, as... Figure 9 As shown, in the first pixel group 010, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002; in the second pixel group 020, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002; in the third pixel group 030, a third type sub-pixel 1003 or a fourth type sub-pixel 1004 is provided between the first type sub-pixel 1001 and the second type sub-pixel 1002.

[0152] In the display substrate provided in this embodiment, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, it is beneficial to improve the color shift problem that occurs when the display substrate displays details such as horizontal lines, vertical lines, and diagonal lines.

[0153] For example, Figure 9 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate provided according to another example of an embodiment of the present disclosure. Figure 9 The example shown is the same as Figure 9 The difference in the example shown is that the first sub-pixel 10 includes a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004, while the third sub-pixel 30 does not include the above four types of sub-pixels.

[0154] For example, such as Figure 9 As shown, at least one first pixel row 01 includes a plurality of first pixel groups 010, each first pixel group 010 including eight sub-pixels, and each first pixel group 010 including a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004. For example, a display substrate includes at least one display area, and each first pixel row 01 located at a non-edge position of the display area includes a plurality of first pixel groups 010. For example, each first pixel row 01 in the display substrate includes a plurality of first pixel groups 010.

[0155] For example, the plurality of first sub-pixels 10 (i.e., red sub-pixels) in each first pixel group 010 include the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004, while the four third sub-pixels 30 do not include the four types of sub-pixels, i.e., the shape, size, and arrangement state of the four third sub-pixels 30 in each first pixel group 010 are all the same.

[0156] For example, as shown in FIG. 1A, the at least one first pixel column 03 includes a plurality of second pixel groups 020, each second pixel group 020 includes eight sub-pixels 100, and each second pixel group 020 includes the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004. Figure 9 For example, the display substrate includes at least one display area, and each first pixel column 03 located at a non-edge position of the display area includes a plurality of second pixel groups 020.

[0157] For example, the plurality of first sub-pixels 10 (i.e., red sub-pixels) in each second pixel group 020 include the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004, while the four third sub-pixels 30 do not include the four types of sub-pixels, i.e., the shape, size, and arrangement state of the four third sub-pixels 30 in each second pixel group 020 are all the same.

[0158] For example, as shown in FIG. 1A, the at least one first pixel column 03 includes a plurality of second pixel groups 020, each second pixel group 020 includes eight sub-pixels 100, and each second pixel group 020 includes the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004. Figure 9 For example, the display substrate includes at least one display area, and each first pixel column 03 located at a non-edge position of the display area includes a plurality of second pixel groups 020.

[0159] For example, each third pixel group 030 includes four first sub-pixels 10 and four second sub-pixels 20, the four first sub-pixels 10 in each third pixel group 030 can be the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004, respectively, while the four second sub-pixels 20 do not include the four types of sub-pixels, i.e., the shape, size, and arrangement state of the four second sub-pixels 20 in each third pixel group 030 are all the same.

[0160] For example, as shown in FIG. 1A, the at least one first pixel column 03 includes a plurality of second pixel groups 020, each second pixel group 020 includes eight sub-pixels 100, and each second pixel group 020 includes the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004. Figure 1As shown, the sub-pixels arranged along the extension direction of the first diagonal and the other diagonal of the virtual quadrilateral include multiple fourth pixel groups 040. Each fourth pixel group 040 includes four sub-pixels, and each fourth pixel group 040 includes two types of sub-pixels among the first type sub-pixel 1001, the second type sub-pixel 1002, the third type sub-pixel 1003, and the fourth type sub-pixel 1004.

[0161] For example, such as Figure 6 As shown, each fourth pixel group 040 includes two first sub-pixels 10 and two second sub-pixels 20. The two first sub-pixels 10 in each fourth pixel group 040 can be any two of the following: first type sub-pixel 1001, second type sub-pixel 1002, third type sub-pixel 1003, and fourth type sub-pixel 1004. The two second sub-pixels 20 do not include the above four types of sub-pixels. That is, the shape, size, and arrangement of the two second sub-pixels 20 in each fourth pixel group 040 are the same.

[0162] In the display substrate provided in this example, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, and setting a fourth pixel group including the above two different types of sub-pixels in another diagonal direction, the color shift problem that occurs when displaying details such as horizontal lines, vertical lines, and diagonal lines on the display substrate can be further improved.

[0163] For example, such as Figure 8 As shown, the four first sub-pixels 10 surrounding each third sub-pixel 30 are respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004.

[0164] In this embodiment of the disclosure, by setting the four first sub-pixels surrounding the third sub-pixel to include four different types of sub-pixels, it is beneficial to reduce color shift and uniformize the visual effect when displaying detailed images with a small number of sub-pixels.

[0165] Of course, when the first sub-pixel includes four types of sub-pixels, the arrangement rules of the four types of sub-pixels are not limited to... Figure 1 The pixel arrangement shown can also be as follows: Figure 1 , Figure 10 or Figure 10 The arrangement of the four types of sub-pixels included in the third sub-pixel in the display substrate shown in the figure is not limited in the embodiments disclosed herein.

[0166] In this example, the length relationship of the straight edges between the corners of the first sub-pixel can be compared with... Figures 1-9 In the example shown, the length relationships of the straight edges between the corners of the third sub-pixel are the same, and will not be repeated here.

[0167] In this example, the relationship between the distances between each corner of the first sub-pixel and the corresponding corner of the adjacent third sub-pixel can be compared with... Figure 10 In the example shown, the distances between each corner of the third sub-pixel and the corresponding corner of the adjacent first sub-pixel are the same, and will not be repeated here.

[0168] For example, Figure 10 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate according to another example of an embodiment of the present disclosure. Figure 10 The example provided shows a display substrate and Figure 10 The difference in the display substrate provided in the example shown is that both the first sub-pixel 10 and the third sub-pixel 30 include a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003, and a fourth type sub-pixel 1004.

[0169] For example, such as Figure 10 As shown, the first pixel group 010, the second pixel group 020, and the third pixel group 030 each include eight sub-pixels, and the fourth sub-pixel group 040 includes four sub-pixels.

[0170] For example, such as Figure 10 As shown, both the first pixel group 010 and the second pixel group 020 include two first type sub-pixels 1001, two second type sub-pixels 1002, two third type sub-pixels 1003, and two fourth type sub-pixels 1004.

[0171] For example, in the same pixel group, the arrangement order of the four types of subpixels included in the first subpixel 10 can be the same as or different from the arrangement order of the four types of subpixels included in the third subpixel 30.

[0172] For example, such as Figure 10 As shown, the third pixel group 030 can include two pixel arrangements. For example, the third pixel group 030 can include four first sub-pixels 10 and four second sub-pixels 20, and the four first sub-pixels 10 can be respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0173] For example, such as Figure 10 As shown, the third pixel group 030 may also include four third sub-pixels 30 and four second sub-pixels 20. The four third sub-pixels 30 may be respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0174] For example, such as Figure 1As shown, the fourth pixel group 040 can include two pixel arrangements. For example, the fourth pixel group 040 can include two first sub-pixels 10 and two second sub-pixels 20, and the two first sub-pixels 10 include two types of sub-pixels.

[0175] For example, such as Figure 6 As shown, the fourth pixel group 040 may include two third sub-pixels 30 and two second sub-pixels 20, and the two third sub-pixels 30 include two types of sub-pixels.

[0176] In the display substrate provided in this example, by setting a first pixel group, a second pixel group, and a third pixel group including the above four different types of sub-pixels in the row direction, column direction, and a diagonal direction respectively, and setting a fourth pixel group including the above two different types of sub-pixels in another diagonal direction, the color shift problem that occurs when displaying details such as horizontal lines, vertical lines, and diagonal lines on the display substrate can be further improved.

[0177] For example, such as Figure 8 As shown, the four first sub-pixels 10 surrounding each third sub-pixel 30 are respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004, and the four third sub-pixels 30 surrounding each first sub-pixel 10 are respectively a first type sub-pixel 1001, a second type sub-pixel 1002, a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0178] In this embodiment of the disclosure, by setting the four first sub-pixels surrounding the third sub-pixel to include four different types of sub-pixels, and setting the four third sub-pixels surrounding the first sub-pixels to include four different types of sub-pixels, it is beneficial to reduce color shift and uniformize the visual effect when displaying detailed images with a small number of sub-pixels.

[0179] Of course, when both the first and third sub-pixels include four types of sub-pixels, the arrangement rules of the four types of sub-pixels included in each sub-pixel are not limited to... Figure 1 The pixel arrangement shown, the arrangement rules of the four types of sub-pixels included in each sub-pixel can be as follows: Figure 1 , Figure 1 or Figure 1 The arrangement of the four types of sub-pixels included in the third sub-pixel in the display substrate shown in the figure is not limited in the embodiments disclosed herein.

[0180] In this example, the length relationship of the straight edges between the corners of the first sub-pixel can be compared with... Figures 1 to 10 In the example shown, the lengths of the straight edges between the corners of the third sub-pixel are the same; in this example, the lengths of the straight edges between the corners of the third sub-pixel can be the same as... Figure 11The length relationship of the straight sides between the corners of the third sub-pixel is the same as that between the corners of the first sub-pixel in the example shown, which will not be described herein again.

[0181] In the example, the size relationship of the distances between the corners of the first sub-pixel and the corresponding corners of the adjacent third sub-pixel can be the same as that between the corners of the third sub-pixel and the corresponding corners of the adjacent first sub-pixel. Figure 11 In the example shown, the size relationship of the distances between the corners of the third sub-pixel and the corresponding corners of the adjacent first sub-pixel is the same as that between the corners of the first sub-pixel and the corresponding corners of the adjacent third sub-pixel; in the example, the size relationship of the distances between the corners of the third sub-pixel and the corresponding corners of the adjacent first sub-pixel can be the same as that between the corners of the first sub-pixel and the corresponding corners of the adjacent third sub-pixel. Figure 11 In the example shown, the size relationship of the distances between the corners of the third sub-pixel and the corresponding corners of the adjacent first sub-pixel is the same as that between the corners of the first sub-pixel and the corresponding corners of the adjacent third sub-pixel; in the example, the size relationship of the distances between the corners of the third sub-pixel and the corresponding corners of the adjacent first sub-pixel can be the same as that between the corners of the first sub-pixel and the corresponding corners of the adjacent third sub-pixel.

[0182] For example, Figure 11 The pixel arrangement structure shown can be located at the edge of the display area of the display substrate or can be located at the non-edge of the display area of the display substrate, and the embodiments of the present disclosure are not limited in this regard.

[0183] For example, the embodiments of the present disclosure are not limited to that each first pixel row includes a first pixel group and / or each first pixel column includes a second pixel group, at least one first pixel row can also include one, two or three of the four types of sub-pixels, and at least one first pixel column can also include one, two or three of the four types of sub-pixels, and the embodiments of the present disclosure are not limited in this regard, as long as the plurality of sub-pixels included in the display substrate include the four types of sub-pixels described above.

[0184] For example, Figure 11 A partial planar structure schematic diagram of a pixel arrangement in a display substrate according to another example of the embodiments of the present disclosure is provided. As shown in Figure 11 As shown, the display substrate includes at least one display area 1000, Figure 11 The display substrate includes one display area, which includes pixel rows and pixel columns located at the four peripheral edges. The embodiments of the present disclosure are not limited in this regard, and the display substrate can also include a plurality of display areas. For example, the display substrate can be a folding display substrate, and according to the folding requirements, the display substrate can include two display areas, four display areas or more display areas, and each display area includes pixel rows and pixel columns located at the four peripheral edges. For example, when two display areas included in the display substrate are adjacent, the pixel rows or pixel columns at the edges of the two display areas can also be adjacent to each other, although the two pixel rows or two pixel columns located at the edges of the two display areas are not located at the edge of the display substrate, the edge pixels of each display area can be designed accordingly according to the requirements.

[0185] For example, as Figure 11As shown, first pixel rows 01 and second pixel rows 02 located at the outermost edge of at least one display area 100 and adjacent to each other constitute an edge pixel row group 012. For example, each display area 1000 may include two edge pixel row groups 012. First pixel columns 03 and second pixel columns 04 located at the outermost edge of at least one display area 1000 and adjacent to each other constitute an edge pixel column group 034. For example, each display area 1000 may include two edge pixel column groups 034. Corner sub-pixels 102 are provided at the intersection of the edge pixel row group 012 and the edge pixel column group 034. The corner sub-pixels 102 include first sub-pixels 10 and third sub-pixels 30. For example, four corner sub-pixels 102 are provided at the intersection of two edge pixel row groups 012 and two edge pixel column groups 034, including two first sub-pixels 10 and two third sub-pixels 30. The outermost edge of the display area mentioned above refers to the outermost edge of the display area that can be lit. A dummy area can be set outside the edge pixel row group (and edge pixel column group) of the outermost edge of the display area; this dummy area will not be lit. Alternatively, the outermost edge of the display area can also refer to the opening of the last row (and last column) pixel definition layer, or the opening of the first row (and first column) pixel definition layer.

[0186] For example, such as Figure 11 As shown, in edge pixel row group 012, at least one of the first sub-pixel 10 and the third sub-pixel 30, excluding corner sub-pixel 102, includes a first corner portion 111 and a second corner portion 112, and the second corner portion 112 is closer to the second pixel row 02 than the first corner portion 111. For example, the first pixel row 01 of edge pixel row group 012 includes only one type of sub-pixel, such as the second type sub-pixel 1002.

[0187] In a typical display substrate, the four corners of the light-emitting areas of each color sub-pixel have the same shape. Therefore, the two pixel rows located at the top and bottom edges of the display area are respectively a row composed of red and blue sub-pixels and a row composed of green sub-pixels. The row composed of red and blue sub-pixels, being the outermost pixel row, is prone to a purplish tinge during display; similarly, the row composed of green sub-pixels, being the outermost pixel row, is prone to a bluish tinge during display. Furthermore, the edges of the light-emitting areas of this type of display substrate may also exhibit jagged edges due to the protruding corners of the sub-pixels.

[0188] With respect to the pixel arrangement of such a display substrate, the display substrate provided by the embodiments of the present disclosure improves the shape of the sub-pixels in the edge pixel row of the display area, so that the second corner of at least one of the blue sub-pixel and the red sub-pixel in the edge pixel row group is located on the side of the first corner close to the green sub-pixel row in the edge pixel row group, so that the brightness center of at least one of the blue sub-pixel and the red sub-pixel is offset to the green sub-pixel, thereby improving the purple or cyan phenomenon of the edge pixel row. In addition, when the most edge pixel row is the first pixel row formed by the blue sub-pixel and the red sub-pixel, the circular chamfer with a longer arc length is used as the first corner located on the edge side, which is beneficial to improve the edge sawtooth feeling.

[0189] For example, as shown in FIG. 1, in the edge pixel column group 034, at least one of the first sub-pixel 10 and the third sub-pixel 30 other than the corner sub-pixel 102 includes a first corner 111 and a second corner 112, and the second corner 112 is closer to the second pixel column 02 than the first corner 111. For example, the first pixel column 03 in the edge pixel column group 034 only includes one type of sub-pixel, for example, the third type of sub-pixel 1003. Figure 11

[0190] In general display substrates, the shapes of the four top corners included in the light-emitting area of each sub-pixel of different colors are the same, and the two pixel columns located at the left and right edges of the display area are a pixel column composed of red sub-pixels and blue sub-pixels and a pixel column composed of green sub-pixels. For the pixel column composed of red sub-pixels and blue sub-pixels as the most edge pixel column, the side edge is prone to appear purple during display. For the pixel column composed of green sub-pixels as the most edge pixel column, the side edge is prone to appear cyan during display. In addition, the edge of the light-emitting area of such a display substrate may also cause a sawtooth-shaped edge during display due to the protruding corners of the sub-pixels.

[0191] With respect to the pixel arrangement of such a display substrate, the display substrate provided by the embodiments of the present disclosure improves the shape of the sub-pixels in the edge pixel row of the display area, so that the second corner of at least one of the blue sub-pixel and the red sub-pixel in the edge pixel row group is located on the side of the first corner close to the green sub-pixel row in the edge pixel row group, so that the brightness center of at least one of the blue sub-pixel and the red sub-pixel is offset to the green sub-pixel, thereby improving the purple or cyan phenomenon of the edge pixel row. In addition, when the most edge pixel row is the first pixel row formed by the blue sub-pixel and the red sub-pixel, the circular chamfer with a longer arc length is used as the first corner located on the edge side, which is beneficial to improve the edge sawtooth feeling.

[0192] For example, as shown in FIG. 1, in the edge pixel column group 034, at least one of the first sub-pixel 10 and the third sub-pixel 30 other than the corner sub-pixel 102 includes a first corner 111 and a second corner 112, and the second corner 112 is closer to the second pixel column 02 than the first corner 111. For example, the first pixel column 03 in the edge pixel column group 034 only includes one type of sub-pixel, for example, the third type of sub-pixel 1003. Figure 11 ​As shown, each first pixel row 01 includes first type sub-pixels 1001, second type sub-pixels 1002, third type sub-pixels 1003 and fourth type sub-pixels 1004, except for the first pixel row 01 located in the edge pixel row group 012. For example, as shown in FIG. 1, the first pixel row 01 includes first type sub-pixels 1001, second type sub-pixels 1002, third type sub-pixels 1003 and fourth type sub-pixels 1004. Figure 12 As shown, each first pixel column 03 includes first type sub-pixels 1001, second type sub-pixels 1002, third type sub-pixels 1003 and fourth type sub-pixels 1004, except for the first pixel column 03 located in the edge pixel column group 034.

[0193] Therefore, the display substrate provided by the embodiments of the present disclosure can make the luminance center of the sub-pixels in the non-edge area of the display area more uniform by adjusting the shape and arrangement of at least one of the first sub-pixel and the third sub-pixel, thereby improving color cast, and improving the phenomenon of purple or cyan at the edge of the display area and the edge sawtooth feeling.

[0194] For example, Figure 12 The edge pixel row group and the edge pixel column group each include sub-pixels with the above-mentioned corner position relationship are described by way of example, but the present disclosure is not limited thereto, and only the edge pixel row group or the edge pixel column group can include sub-pixels with the above-mentioned corner position relationship. The above-mentioned corner position relationship refers to the position relationship between the first corner and the second corner in at least one of the first sub-pixel and the third sub-pixel in the first pixel row group or the first pixel column group and the second pixel row or the second pixel column.

[0195] For example, as shown in FIG. 1, the first sub-pixel 10 and the third sub-pixel 30 in the edge pixel row group 012, except for the corner sub-pixel 102, each include a first corner 111 and a second corner 112, and the second corner 112 is located on the side of the first corner 111 close to the second pixel row 02; the first sub-pixel 10 and the third sub-pixel 30 in the edge pixel column group 034, except for the corner sub-pixel 102, each include a first corner 111 and a second corner 112, and the second corner 112 is located on the side of the first corner 111 close to the second pixel column 04. Figure 11 For example, the first pixel row in the edge pixel row group and the first pixel column in the edge pixel column group each include only one type of sub-pixel, and the type of the sub-pixel included in the edge pixel row group is different from the type of the sub-pixel included in the edge pixel column group. For example, the direction in which the first corner of the sub-pixel in the edge pixel row group points to the second corner intersects the direction in which the first corner of the sub-pixel in the edge pixel column group points to the second corner. For example, the direction in which the first corner of the sub-pixel in the edge pixel row group points to the second corner is parallel to the column direction, and the direction in which the first corner of the sub-pixel in the edge pixel column group points to the second corner is parallel to the row direction.

[0196]

[0197] ​The display substrate provided by the embodiment of the present disclosure can better improve the phenomenon of purple or cyan at the edge of the display area by setting the blue sub-pixel and the red sub-pixel to have the above-mentioned corner position relationship, so that the brightness centers of the blue sub-pixel and the red sub-pixel at the edge are both offset to the green sub-pixel. The above-mentioned corner position relationship refers to the position relationship between the first corner and the second corner in at least one of the first sub-pixel and the third sub-pixel in the first pixel row group or the first pixel column group and the second pixel row or the second pixel column.

[0198] For example, as shown in FIG. 1, the direction in which the first corner 111 of the edge corner sub-pixel 102 points to the second corner 112 can be the same as the direction in which the first corner 111 of the sub-pixel in the edge pixel row group 012 points to the second corner 112, or can be the same as the direction in which the first corner 111 of the sub-pixel in the edge pixel column group 034 points to the second corner 112, and the embodiment of the present disclosure does not limit this. Figure 13

[0199] For example, as shown in FIG. 1, the direction in which the first corner 111 of the edge corner sub-pixel 102 points to the second corner 112 can be the same as the direction in which the first corner 111 of the sub-pixel in the edge pixel row group 012 points to the second corner 112, or can be the same as the direction in which the first corner 111 of the sub-pixel in the edge pixel column group 034 points to the second corner 112, and the embodiment of the present disclosure does not limit this. Figure 13 A partial plane structure schematic diagram of pixel arrangement in a display substrate according to another example of the embodiment of the present disclosure is provided. Figure 12 The difference between the example shown in FIG. 1 and the example shown in FIG. 2 is that in at least one of the edge pixel row group 012 and the edge pixel column group 034, only the second corner 112 of the third sub-pixel 30 is located on the side of the first corner 111 close to the second pixel row 02 or the second pixel column 04, and the first sub-pixel 10 located in at least one of the edge pixel row group 012 and the edge pixel column group 034 includes four types of sub-pixels, that is, in at least one of the edge pixel row group 012 and the edge pixel column group 034, the first sub-pixel 10 includes four types of sub-pixels, and the third sub-pixel 30 includes only one type of sub-pixel. Figure 13 The example adjusts the position of the brightness center of the third sub-pixel at the edge by setting the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to have the second corner located on the side of the first corner close to the second pixel row or the second pixel column, which is conducive to improving the phenomenon of purple or cyan at the edge of the display area. In addition, setting the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to include four different types of sub-pixels is also conducive to reducing the color deviation problem when displaying horizontal lines or vertical lines and other details at the edge.

[0200]

[0201] ​​Of course, the embodiments of the present disclosure are not limited to this, in another example of the present disclosure, the second corner of the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group is located on the side of the first corner close to the second pixel row or the second pixel column, and the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group comprises four types of sub-pixels. For example, in at least one of the edge pixel row group and the edge pixel column group, the third sub-pixel comprises four types of sub-pixels, and the first sub-pixel comprises only one type of sub-pixel. The present example is advantageous in improving the purple or cyan phenomenon of the edge of the display area by setting the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to have its second corner located on the side of the first corner close to the second pixel row or the second pixel column to adjust the position of the brightness center of the first sub-pixel of the edge. In addition, setting the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to comprise four different types of sub-pixels is also advantageous in reducing the color deviation problem when displaying horizontal lines or vertical lines and the like details of the edge.

[0202] For example, Figure 14 A partial planar structure schematic diagram of pixel arrangement in a display substrate according to another example of the embodiments of the present disclosure is provided. Figure 15 The example shown is different from Figure 14 The example shown is different from Figure 14 In the display substrate shown, only the third sub-pixel 30 comprises four types of sub-pixels, and the first sub-pixel 10 does not comprise four types of sub-pixels, that is, the shape, size and arrangement state of the plurality of first sub-pixels 10 in the display substrate are all the same.

[0203] The present example is advantageous in improving the purple or cyan phenomenon of the edge of the display area by setting the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to have its second corner located on the side of the first corner close to the second pixel row or the second pixel column to adjust the position of the brightness center of the third sub-pixel of the edge.

[0204] Of course, the embodiments of the present disclosure are not limited to this, in another example of the present disclosure, the second corner of the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group is located on the side of the first corner close to the second pixel row or the second pixel column, and the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group comprises four types of sub-pixels. For example, in at least one of the edge pixel row group and the edge pixel column group, the third sub-pixel comprises four types of sub-pixels, and the first sub-pixel comprises only one type of sub-pixel. The present example is advantageous in improving the purple or cyan phenomenon of the edge of the display area by setting the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to have its second corner located on the side of the first corner close to the second pixel row or the second pixel column to adjust the position of the brightness center of the first sub-pixel of the edge. In addition, setting the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group of the display area to comprise four different types of sub-pixels is also advantageous in reducing the color deviation problem when displaying horizontal lines or vertical lines and the like details of the edge of the display area.

[0205] For example, Figure 11 A partial planar structure schematic diagram of pixel arrangement in a display substrate according to another example of the embodiments of the present disclosure is provided.Figure 11 for Figure 14 The image shown is a magnified view of a corner sub-pixel. Figure 15 The example shown is the same as Figure 14 The difference in the example shown is that the shape of the corner sub-pixels 102 of the display substrate in this example is different. Figure 15 The shape of the corner sub-pixels 102 of the display substrate is shown.

[0206] For example, such as Figure 14 and Figure 11 As shown, in the corner sub-pixel 102, the distance from the intersection point Q1 of the extensions of the two straight edges constituting the third corner 113 to the center P of the sub-pixel 102 is greater than the distance from the intersection point Q2 of the two straight edges or their extensions constituting the fourth corner 114 to the center P of the sub-pixel 102, and the fourth corner 114 is closer to the second pixel row 02 or the second pixel column 04 adjacent to the corner sub-pixel 102 than the third corner 113.

[0207] This embodiment of the invention adjusts the shape relationship between the third and fourth corner portions of the corner sub-pixels, which can shift the brightness center of the blue or red corner sub-pixels located at the four corners of the display area toward the adjacent green sub-pixel row and column, thus helping to improve the purple or blue coloration at the corners of the display area.

[0208] For example, such as Figure 14 and Figure 16 As shown, in the corner sub-pixels 102, the shape of the first corner 111 can be approximately the same as the shape of the third corner 113, and the shape of the fourth corner 114 can be approximately the same as the shape of the second corner 112.

[0209] Figure 16 The example shown schematically illustrates the pixel shape and arrangement pattern in the display area of ​​the display substrate, excluding the corner sub-pixels. Figure 16 The display substrate shown has the same pixel shape and arrangement pattern in the display area except for the corner sub-pixels, but it is not limited to this. Figure 1 The shapes of the corner sub-pixels and the relationships between the corners shown can be applied to the display substrate provided in any of the above examples to improve the display effect at the corners of the display area.

[0210] Figure 15 This is a partial structural schematic diagram of a display substrate provided according to an embodiment of the present disclosure. Figure 16 As shown, the display substrate includes multiple sub-pixels 100. Figure 16 As shown, the plurality of sub-pixels 100 includes a plurality of first sub-pixels 10, a plurality of second sub-pixels 20, and a plurality of third sub-pixels 30. The plurality of first sub-pixels 10 and the plurality of third sub-pixels 30 are arranged along the row direction (e.g., ...). Figure 16 (as shown in the X direction) and column direction (e.g.)Figure 16 The first sub-pixels 10 and the third sub-pixels 30 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable.

[0211] As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figures 1 to 14 As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable.

[0212] As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figure 16 As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figure 16 As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable.

[0213] As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figure 16 As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figure 16 The sub-pixels including the first corner portion 111 and the second corner portion 112 in the example shown in FIG. 1 have the same features and technical effects, which are not described here again.

[0214] As shown in FIG. 1, the first sub-pixels 10 and the third sub-pixels 30 in the first pixel row 01 are alternately arranged along the Y direction (as shown in FIG. 1) to form a plurality of first pixel rows 01 and a plurality of first pixel columns 03, and the second sub-pixels 20 are arranged in an array along the row direction and the column direction to form a plurality of second pixel rows 02 and a plurality of second pixel columns 04, the row direction and the column direction intersecting each other. For example, the row direction and the column direction can be perpendicular. The row direction and the column direction can be interchangeable. Figure 1As shown, a first pixel row 01 and a second pixel row 02 located at the outermost edge of at least one display area 1000 and adjacent to each other constitute an edge pixel row group 012. A first pixel column 03 and a second pixel column 04 located at the outermost edge of at least one display area 1000 and adjacent to each other constitute an edge pixel column group 034. Corner sub-pixels 102 are provided at the intersection of the edge pixel row group 012 and the edge pixel column group 034. The corner sub-pixels 102 include a first sub-pixel 10 and a third sub-pixel 30. For example, four corner sub-pixels 102 are provided at the intersection of two edge pixel row groups 012 and two edge pixel column groups 034, including two first sub-pixels 10 and two third sub-pixels 30.

[0215] like Figure 16 As shown, in the edge pixel row group 012, among the sub-pixels 100 excluding the corner sub-pixels 102, the second corner 112 is closer to the second pixel row 02 than the first corner 111.

[0216] In a typical display substrate, the four corners of the light-emitting areas of each color sub-pixel have the same shape. Therefore, the two pixel rows located at the top and bottom edges of the display area are respectively a row composed of red and blue sub-pixels and a row composed of green sub-pixels. The row composed of red and blue sub-pixels, being the outermost pixel row, is prone to a purplish tinge during display; similarly, the row composed of green sub-pixels, being the outermost pixel row, is prone to a bluish tinge during display. Furthermore, the edges of the light-emitting areas of this type of display substrate may also exhibit jagged edges due to the protruding corners of the sub-pixels.

[0217] Compared to the pixel arrangement of this display substrate, the display substrate provided in this embodiment improves the shape of the sub-pixels in the edge pixel rows of the display area. The second corner of at least one of the blue and red sub-pixels in the edge pixel row group is located on the side of the first corner closer to the green sub-pixel row in the edge pixel row group. This shifts the brightness center of at least one of the blue and red sub-pixels towards the green sub-pixel, thus improving the purple or bluish tinge that appears in the edge pixel rows. Furthermore, when the outermost pixel row is the first pixel row formed by blue and red sub-pixels, a rounded chamfer with a longer arc length serves as the first corner on the edge side, which helps to improve the jagged edge appearance.

[0218] like Figure 16 As shown, in the edge pixel column group 034, among the sub-pixels 100 excluding the corner sub-pixels 102, the second corner 112 is closer to the second pixel column 04 than the first corner 111.

[0219] In a typical display substrate, the four corners of the light-emitting areas of each color sub-pixel have the same shape. Therefore, the two pixel columns located at the left and right edges of the display area are respectively a pixel column composed of red and blue sub-pixels and a pixel column composed of green sub-pixels. The pixel column composed of red and blue sub-pixels, being the outermost pixel column, is prone to a purplish hue during display; similarly, the pixel column composed of green sub-pixels, also being the outermost pixel column, is prone to a bluish hue. Furthermore, the edges of the light-emitting areas of this type of display substrate may also exhibit jagged edges due to the protruding corners of the sub-pixels.

[0220] Compared to the pixel arrangement of this display substrate, the display substrate provided in this embodiment improves the shape of the sub-pixels in the edge pixel column of the display area. The second corner of at least one of the blue and red sub-pixels in the edge pixel column is located on the side of the first corner closer to the green sub-pixel column in the edge pixel column. This shifts the brightness center of at least one of the blue and red sub-pixels towards the green sub-pixel, thus improving the purple or bluish tinge that appears in the edge pixel column. Furthermore, when the outermost pixel column is the first pixel column formed by blue and red sub-pixels, a rounded chamfer with a longer arc length as the first corner on the edge side helps to improve the jagged edge appearance.

[0221] For example, such as Figure 16 As shown, at least one of the first sub-pixel 10 and the third sub-pixel 30 in the display substrate includes Figure 17 The four types of sub-pixels shown are: first type sub-pixel 1001, second type sub-pixel 1002, third type sub-pixel 1003, and fourth type sub-pixel 1004. For example, in the sub-pixels located outside the display area, the first pixel row 01 includes two types of sub-pixels, and the first pixel column 03 includes two types of sub-pixels. For example, the two types of sub-pixels included in each first pixel row 01 are arranged alternately. For example, each first pixel column 03 includes two types of sub-pixels arranged alternately.

[0222] For example, such as Figure 17 As shown, two adjacent first pixel rows 01 include sub-pixels of different types. For example, one first pixel row 01 includes a first type sub-pixel 1001 and a second type sub-pixel 1002, while the first pixel row 01 adjacent to this first pixel row 01 includes a third type sub-pixel 1003 and a fourth type sub-pixel 1004. Similarly, two adjacent first pixel columns 03 include sub-pixels of different types. For example, one first pixel column 03 includes a first type sub-pixel 1001 and a second type sub-pixel 1002, while the first pixel column 03 adjacent to this first pixel column 03 includes a third type sub-pixel 1003 and a fourth type sub-pixel 1004.

[0223] Of course, the embodiments of the present disclosure are not limited thereto, each first pixel row can include two types of sub-pixels which are one of the first type sub-pixel and the second type sub-pixel, and one of the third type sub-pixel and the fourth type sub-pixel; and each first pixel column can include two types of sub-pixels which are one of the first type sub-pixel and the second type sub-pixel, and one of the third type sub-pixel and the fourth type sub-pixel.

[0224] For example, as shown in FIG. 10, four third sub-pixels 30 surrounding the first sub-pixel 10 include four types of sub-pixels. Figure 16

[0225] Figure 17 For example, as shown in FIG. 10, four third sub-pixels 30 surrounding the first sub-pixel 10 include four types of sub-pixels.

[0226] For example, as shown in FIG. 10, four third sub-pixels 30 surrounding the first sub-pixel 10 include four types of sub-pixels. Figure 11 A partial planar structure schematic diagram of pixel arrangement in a display substrate according to another example of the embodiments of the present disclosure is provided as follows, Figures 12-13 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that, Figure 18 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that, Figure 18 In the display substrate shown in FIG. 12, the first sub-pixel 10 and the third sub-pixel 30 in the edge pixel row group 012 except the corner sub-pixel 102 all include the first corner 111 and the second corner 112, and the first sub-pixel 10 and the third sub-pixel 30 in the edge pixel column group 034 except the corner sub-pixel 102 all include the first corner 111 and the second corner 112. The distribution rule and shape features of the sub-pixels in the edge pixel row group and the edge pixel column group in the example and the corresponding technical effects can be the same as those of the example shown in FIG. 11, and will not be repeated here. Of course, the example is not limited thereto, and the distribution rule and shape features of the sub-pixels in the edge pixel row group and the edge pixel column group in the example and the corresponding technical effects can also be the same as those of the example shown in FIG. 10. Figure 17 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that, Figure 18 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that,

[0227] For example, as shown in FIG. 10, four third sub-pixels 30 surrounding the first sub-pixel 10 include four types of sub-pixels. Figure 11 A partial planar structure schematic diagram of pixel arrangement in a display substrate according to another example of the embodiments of the present disclosure is provided as follows, Figures 12-13 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that, Figure 18 The difference between the example shown in FIG. 12 and the example shown in FIG. 11 is that, Figure 19 ​In the display substrate shown, each sub-pixel located outside the display area does not include the first and second corner portions with the aforementioned characteristics; that is, the shapes of the four corner portions of each sub-pixel located outside the display area are approximately the same. The distribution patterns, shapes, and other characteristics of the sub-pixels in the edge pixel rows and column groups, as well as the corresponding technical effects, in this example can be compared with... Figure 19 The distribution patterns, shapes, and other features of sub-pixels in the edge pixel row groups and edge pixel column groups shown are the same as those, and the corresponding technical effects will not be repeated here. Of course, this example is not limited to this; the distribution patterns, shapes, and other features of sub-pixels in the edge pixel row groups and edge pixel column groups, and the corresponding technical effects, can also be... Figure 17 The distribution patterns, shapes, and other features of sub-pixels in the edge pixel row groups and edge pixel column groups shown in the example are the same, as are the corresponding technical effects.

[0228] For example, such as Figure 17 As shown, the area of ​​the third sub-pixel in at least one of the edge pixel row group and the edge pixel column group is smaller than the area of ​​the third sub-pixel in the non-edge region of the at least one display area; and / or, the area of ​​the first sub-pixel in at least one of the edge pixel row group and the edge pixel column group is smaller than the area of ​​the first sub-pixel in the non-edge region of the at least one display area. For example, when the shapes of the four corners of each sub-pixel located on the non-edge of the display area are approximately the same, the shape of the first sub-pixel located on the edge of the display area is different from the shape of the first sub-pixel located on the non-edge of the display area, and the area of ​​the first sub-pixel located on the edge of the display area is smaller than the area of ​​the first sub-pixel located on the non-edge of the display area. For example, when the shapes of the four corners of each sub-pixel located on the non-edge of the display area are approximately the same, the shape of the third sub-pixel located on the edge of the display area is different from the shape of the third sub-pixel located on the non-edge of the display area, and the area of ​​the third sub-pixel located on the edge of the display area is smaller than the area of ​​the third sub-pixel located on the non-edge of the display area.

[0229] For example, Figure 14 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate according to another example of an embodiment of the present disclosure. Figure 15 The example shown is the same as Figure 19 The difference in the example shown is that the shape of the corner sub-pixels 102 of the substrate in this example is different. Figure 15 The shape of the corner sub-pixels 102 of the display substrate is shown. In this example, the shape of the corner sub-pixels 102 can be compared with... Figure 19 and Figure 19 The corner sub-pixels 102 shown have the same shape. For example... Figures 1-18 and Figure 19As shown, the apex of the light-emitting area 110 of the corner sub-pixel 102 also includes a third corner portion 113 and a fourth corner portion 114 disposed opposite to each other; in the corner sub-pixel 102, the distance from the intersection point Q1 of the extension lines of the two straight edges constituting the third corner portion 113 to the center P of the sub-pixel 102 is greater than the distance from the intersection point Q2 of the two straight edges or their extension lines constituting the fourth corner portion 114 to the center P of the sub-pixel 102, and the fourth corner portion 114 is closer to the second pixel row 02 or the second pixel column 04 adjacent to the corner sub-pixel 102 than the third corner portion 113.

[0230] This embodiment of the invention adjusts the shape relationship between the third and fourth corner portions of the corner sub-pixels, which can shift the brightness center of the blue or red corner sub-pixels located at the four corners of the display area toward the adjacent green sub-pixel row and column, thus helping to improve the purple or blue coloration at the corners of the display area.

[0231] For example, such as Figure 20 As shown, in the corner sub-pixels 102, the shape of the first corner 111 can be approximately the same as the shape of the third corner 113, and the shape of the fourth corner 114 can be approximately the same as the shape of the second corner 112.

[0232] Figure 20 The example shown schematically illustrates the pixel shape and arrangement pattern in the display area of ​​the display substrate, excluding the corner sub-pixels. Figure 11 The pixel shapes and arrangement patterns in the display area of ​​any of the shown display substrates are the same, except for the corner sub-pixels, but are not limited thereto. Figure 20 The shapes of the corner sub-pixels and the relationships between the corners shown can be applied to the display substrate provided in any of the above examples to improve the display effect at the corners of the display area.

[0233] For example, Figure 20 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate according to another example of an embodiment of the present disclosure. Figure 20 The example shown is the same as Figures 1 to 19 The difference in the example shown is that, in this example, the second sub-pixel 20 of at least one of the edge pixel row group and edge pixel column group in the display area of ​​the display substrate includes a first corner 111 and a second corner 112 opposite to each other, and the distance from the intersection of the extension line of the two sides constituting the first corner 111 or the tangent line of the two sides to the center of the sub-pixel is greater than the distance from the intersection of the two sides constituting the second corner 112 or their extension line or the tangent line of the two sides to the center of the sub-pixel.

[0234] For example, such as Figure 21 As shown, each second sub-pixel 20 in the edge pixel row group 012 and edge pixel column group 034 in the display area includes a first corner portion 111 and a second corner portion 112 having the above-mentioned relationship.

[0235] For example, such as Figure 21 As shown, in edge pixel row group 012, the second corner 112 of the second sub-pixel 20 is closer to the first pixel row 01 than the first corner 111, thereby making the brightness center of the second sub-pixel, which is a green sub-pixel, closer to the first pixel row; in edge pixel column group 034, the second corner 112 of the second sub-pixel 20 is closer to the first pixel column 03 than the first corner 111, thereby making the brightness center of the second sub-pixel, which is located at the edge of the display area and is a green sub-pixel, closer to the first pixel column, so as to further alleviate the problem of purple or blue edges when the display area of ​​the display substrate is displayed.

[0236] For example, such as Figure 20 As shown, in this example, the second sub-pixel 20 located in the non-edge area of ​​the display area may not include the first corner and the second corner that have the above relationship, that is, the four vertices of the second sub-pixel 20 located in the non-edge area of ​​the display area are all the same shape.

[0237] In this example, the intersection of the second pixel row and the second pixel column in the edge pixel row group and the edge pixel column group also includes a green corner sub-pixel. This green corner sub-pixel may have the same characteristics as the corner sub-pixels included in the first or third sub-pixel mentioned above, which will not be elaborated here.

[0238] In this example, the shape and arrangement of the first and third sub-pixels of the display area edge and non-edge areas can be compared with... Figure 21 In any example, the shapes and arrangement patterns of the first and third sub-pixels are the same, and will not be repeated here.

[0239] For example, Figure 1 This is a schematic diagram of a partial planar structure of pixel arrangement in a display substrate according to another example of an embodiment of the present disclosure. Figures 1 to 19 The example shown is the same as Figure 1 The difference in the example shown is that, in this example, the second sub-pixel 20 of the non-edge area of ​​the display area in the display substrate includes a first corner 111 and a second corner 112 that are opposite to each other. The distance from the intersection of the extension line of the two sides constituting the first corner 111 or the tangent line of the two sides to the center of the sub-pixel is greater than the distance from the intersection of the two sides constituting the second corner 112 or their extension line or the tangent line of the two sides to the center of the sub-pixel.

[0240] For example, such as Figure 6 As shown, based on the direction from the first corner 111 to the second corner 112, the second sub-pixel 20 can also be divided into a first type sub-pixel, a second type sub-pixel, a third type sub-pixel, and a fourth type sub-pixel. The definition method of these four types of sub-pixels is the same as... Figure 1The four types of sub-pixels are defined in the same way, but in this example, the direction in which the first corner of each type of sub-pixel points to the second corner is no longer parallel to the row direction and the column direction. As shown in FIG. 1A, the second sub-pixels 20 arranged along the row direction include two types of sub-pixels arranged alternately, the second sub-pixels 20 arranged along the column direction include another two types of sub-pixels arranged alternately, and the four second sub-pixels 20 surrounding the first sub-pixel include four types of sub-pixels; the four second sub-pixels 20 surrounding the third sub-pixel include four types of sub-pixels. Figure 1 As shown in FIG. 1A, the second sub-pixels 20 arranged along the row direction include two types of sub-pixels arranged alternately, the second sub-pixels 20 arranged along the column direction include another two types of sub-pixels arranged alternately, and the four second sub-pixels 20 surrounding the first sub-pixel include four types of sub-pixels; the four second sub-pixels 20 surrounding the third sub-pixel include four types of sub-pixels.

[0241] The embodiments of the present disclosure are not limited to this, and the second sub-pixels arranged along the row direction can also include four types of sub-pixels, and the second sub-pixels arranged along the column direction can also include four types of sub-pixels.

[0242] Of course, the shapes and arrangement rules of the first sub-pixels and the third sub-pixels in the display area edge and the non-edge area in this example can be the same as those in the first example, and are not described here again. Figure 1 The shapes and arrangement rules of the first sub-pixels and the third sub-pixels in any example are the same, and are not described here again.

[0245] ​For example, the center of the sub-pixel is, for example, the geometric center of the sub-pixel, or the intersection of the perpendicular bisectors of the edges of the sub-pixel, or a point in the sub-pixel that is approximately equidistant from the edges. Of course, the center of the sub-pixel can be allowed to have some error.
