[0002] At least one embodiment of the present disclosure relates to a display substrate and a display device. Background Art

[0003] An Organic Light-Emitting Display (OLED) is a self-luminous device with a series of advantages such as high brightness, full viewing angle, fast response speed, and flexible display. In an organic light-emitting diode display device, the arrangement of the three conventional color sub-pixels of red, green, and blue can be changed (for example, the virtual pixel method of sharing some sub-pixels to reduce the number of sub-pixels). On the premise that the image resolution is the same, the density of physical sub-pixels can be reduced. Summary of the Invention

[0004] At least one embodiment of the present disclosure provides a display substrate and a display device.

[0005] At least one embodiment of the present disclosure provides a display substrate, including: a plurality of sub-pixels, including a plurality of first-color sub-pixels, a plurality of second-color sub-pixels, and a plurality of third-color sub-pixels; the plurality of first-color sub-pixels and the plurality of third-color sub-pixels are alternately arranged along both the row direction and the column direction to form a plurality of first pixel rows and a plurality of first pixel columns, the plurality of second-color sub-pixels are arranged in an array along both 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 are offset from each other in the row direction, and the plurality of first pixel columns and the plurality of second pixel columns are alternately arranged along the row direction and are offset from each other in the column direction. The plurality of sub-pixels include a plurality of light-emitting regions, and each side or its extension line of each light-emitting region is sequentially connected to form a polygon, and there are regions where the plurality of vertices of the polygon of at least some sub-pixels do not overlap with the plurality of corners of the corresponding light-emitting region; among the plurality of corners of the light-emitting region of at least one sub-pixel, at least a first corner is included, and the area of the region where the first corner does not overlap with the vertex of the corresponding polygon is larger than the area of the region where each of at least some other corners does not overlap with the vertex of the corresponding polygon.

[0006] For example, in an embodiment of the present disclosure, the corners of the light-emitting regions of at least two different color sub-pixels include the first corner, and the number of the first corners in the at least two different color sub-pixels is different.

[0007] For example, in an embodiment of the present disclosure, the areas of the light-emitting regions of sub-pixels of the same color are the same, and the areas of the light-emitting regions of sub-pixels of different colors are different.

[0008] For example, in an embodiment of the present disclosure, each side or its extension line of the light-emitting region of the first color sub-pixel is sequentially connected to form a first polygon, each side or its extension line of the second color sub-pixel is sequentially connected to form a second polygon, and each side or its extension line of the light-emitting region of the third color sub-pixel is sequentially connected to form a third polygon, and at least two of the first polygon, the second polygon, and the third polygon are similar figures.

[0009] For example, in an embodiment of the present disclosure, in the same sub-pixel, the shortest distance between the two straight sides connecting the two ends of the first corner is not greater than the length of the line connecting the vertices of the two corners adjacent to the first corner in the sub-pixel.

[0010] For example, in an embodiment of the present disclosure, the lengths of the two straight sides connecting the two ends of the first corner are both not less than 3 micrometers.

[0011] For example, in an embodiment of the present disclosure, the light-emitting region of at least one sub-pixel having the first corner is an axisymmetric figure, and at least one axis of symmetry in the axisymmetric figure coincides with the bisector of the first corner.

[0012] For example, in an embodiment of the present disclosure, in the same sub-pixel, the line connecting the vertices of the two corners adjacent to the first corner divides the sub-pixel into two parts, and the areas of the two parts are different.

[0013] For example, in an embodiment of the present disclosure, in the same sub-pixel, the line connecting the vertices of the two corners adjacent to the first corner divides the sub-pixel into two parts, and the area ratio of the two parts is 0.1 - 10.

[0014] For example, in an embodiment of the present disclosure, the third color subpixel includes the first corner, and a line connecting two corner vertices adjacent to the first corner of the third color subpixel divides the third color subpixel into a first part and a second part. The first part includes the first corner, and the area of the first part is smaller than the area of the second part. The luminous efficiency of the third color subpixel is less than that of the second color subpixel, and the second part of the third color subpixel is closer to the second color subpixel that is driven in the same row as the third color subpixel and adjacent to the third color subpixel.

[0015] For example, in an embodiment of the present disclosure, the shape of the light-emitting region is the shape after at least one vertex angle of the polygon is cut off. The first corner is the corner formed after the first vertex angle sandwiched by two first sides of the polygon is cut off, and the ratio of the length of the cut-off part of at least one of the two first sides to the length of the first side is 0.2 to 0.8.

[0016] For example, in an embodiment of the present disclosure, a subpixel includes the first corner. Another color subpixel adjacent to the subpixel in at least one of the row direction and the column direction does not include the first corner, or all the corner parts included in the light-emitting region of the another color subpixel are the first corner. The connection line between the geometric centers of the light-emitting regions of the subpixel and the adjacent another color subpixel is not parallel to both the row direction and the column direction.

[0017] For example, in an embodiment of the present disclosure, the first color subpixel, the second color subpixel, and the third color subpixel all include the first corner, and the number of the first corners in different color subpixels is different.

[0018] For example, in an embodiment of the present disclosure, in at least one of the first color subpixel, the second color subpixel, and the third color subpixel, the corner part of the light-emitting region further includes a second corner. The distance from the intersection point of the two sides or their extension lines connecting the two end points of the first corner to the geometric center of the light-emitting region of the subpixel is greater than the distance from the intersection point of the two sides or their extension lines forming the second corner to the geometric center.

[0019] For example, in an embodiment of the present disclosure, the outer edge shape of the first corner includes a line segment, and the ratio of the lengths of the outer edges of the first corners in different color subpixels is 0.8 to 1.2; or, the outer edge shape of the first corner includes an arc, and the ratio of the radian measures of the outer edges of the first corners in different color subpixels is 0.8 to 1.2.

[0020] For example, in an embodiment of the present disclosure, the second corner is a corner formed after the polygon has its second vertex angle clamped by two second sides or its second vertex angle clamped by one first side and one second side removed, and the ratio of the length of the removed part of at least one of the first side and the second side to the length of this side is 0.05 to 0.2.

[0021] For example, in an embodiment of the present disclosure, the outer edge shape of the second corner includes a line segment, and the ratio of the lengths of the outer edges of the second corner in different color sub-pixels is 0.8 to 1.2; or, the outer edge shape of the second corner includes an arc, and the ratio of the radian measures of the outer edges of the second corner in different color sub-pixels is 0.8 to 1.2.

[0022] For example, in an embodiment of the present disclosure, among the corners of at least part of the light-emitting region, the corners other than the first corner are all the second corners.

[0023] For example, in an embodiment of the present disclosure, at least part of the light-emitting region includes four corners. Among the four corners of one color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, the first corner is not included. The number of first corners included in the four corners of the other two color sub-pixels among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel is different; or, the number of first corners included in the four corners of two color sub-pixels among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel is the same, and the number of first corners included in the four corners of the other color sub-pixel is different from the number of first corners of the two color sub-pixels; or, the four corners of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel all include the first corner, and the number of first corners in different color sub-pixels is different.

[0024] For example, in an embodiment of the present disclosure, among the four corners of one color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, two, three, or four first corners are included, and among the four corners of at least one of the other two color sub-pixels among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, one first corner is included.

[0025] For example, in an embodiment of the present disclosure, all four corners of one type of color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are the first corners. The four corners of another type of color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel include two first corners. The four corners of the other color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel include one first corner.

[0026] For example, in an embodiment of the present disclosure, the four corners of two types of color sub-pixels among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel include one first corner. The four corners of the other color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel include three first corners.

[0027] For example, in an embodiment of the present disclosure, the first color sub-pixel is a red sub-pixel, the second color sub-pixel is a green sub-pixel, and the third color sub-pixel is a blue sub-pixel.

[0028] For example, in an embodiment of the present disclosure, at least one type of color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel includes the first corner and the second corner. The second corner includes a corner opposite to the first corner. The at least one type of color sub-pixel includes the same type of sub-pixels. In this type of sub-pixels, the directions from the vertex of the first corner to the vertex of the second corner opposite thereto are all the same.

[0029] For example, in an embodiment of the present disclosure, at least one type of color sub-pixel among the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel includes the first corner and the second corner. The second corner includes a corner opposite to the first corner. The at least one type of color sub-pixel includes at least two types of sub-pixels. In different types of sub-pixels, the directions from the vertex of the first corner to the vertex of the second corner opposite thereto are different.

[0030] For example, in an embodiment of the present disclosure, among two adjacent sub-pixels in at least one of the row direction and the column direction in the same type of color sub-pixels having different types of sub-pixels, the two sub-pixels are of different types.

[0031] For example, in an embodiment of the present disclosure, among two adjacent sub-pixels in at least one of the row direction and the column direction, the direction from the vertex of the first corner to the vertex of the second corner opposite thereto is opposite.

[0032] For example, in an embodiment of the present disclosure, the at least two types of sub-pixels include a first type of sub-pixel, a second type of sub-pixel, a third type of sub-pixel, and a fourth type of sub-pixel. In the first type of sub-pixel and the second type of sub-pixel, the vertex of the first corner points in the opposite direction to the vertex of the second corner opposite thereto, and is parallel to one of the row direction and the column direction; in the third type of sub-pixel and the fourth type of sub-pixel, the vertex of the first corner points in the opposite direction to the vertex of the second corner opposite thereto, and is parallel to the other of the row direction and the column direction. The plurality of first pixel rows include a first sub-pixel row and a second sub-pixel row alternately arranged along the column direction. In the first sub-pixel row, the sub-pixels of the same color include the first type of sub-pixel and the second type of sub-pixel alternately arranged along the row direction. In the second sub-pixel row, the sub-pixels of the same color include the third type of sub-pixel and the fourth type of sub-pixel alternately arranged along the row direction. The plurality of first pixel columns include a first sub-pixel column and a second sub-pixel column alternately arranged along the row direction. In the first sub-pixel column, the sub-pixels of the same color include the first type of sub-pixel and the second type of sub-pixel alternately arranged along the column direction. In the second sub-pixel column, the sub-pixels of the same color include the third type of sub-pixel and the fourth type of sub-pixel alternately arranged along the column direction.

[0033] For example, in an embodiment of the present disclosure, at least one of the third color sub-pixel and the first color sub-pixel includes the first type of sub-pixel, the second type of sub-pixel, the third type of sub-pixel, and the fourth type of sub-pixel.

[0034] For example, in an embodiment of the present disclosure, the third color sub-pixel includes the first type of sub-pixel, the second type of sub-pixel, the third type of sub-pixel, and the fourth type of sub-pixel. Among the four corners of the sub-pixels of one color in the third color sub-pixel and the first color sub-pixel, there is one first corner, and among the four corners of the sub-pixels of the other color, there are at most three first corners; or, among the four corners of the sub-pixels of one color in the third color sub-pixel and the first color sub-pixel, there are two first corners, and among the four corners of the sub-pixels of the other color, there are two or three first corners; or, both the third color sub-pixel and the first color sub-pixel include three first corners.

[0035] For example, in an embodiment of the present disclosure, at least a portion of the four corners of the second color sub-pixels includes at least one first corner. The second color sub-pixels include fifth-type sub-pixels, sixth-type sub-pixels, seventh-type sub-pixels, and eighth-type sub-pixels. Among different types of sub-pixels, the direction in which the vertex of the first corner points to the vertex of the second corner opposite thereto is different; among the fifth-type sub-pixels, the sixth-type sub-pixels, the seventh-type sub-pixels, and the eighth-type sub-pixels, the directions in which the vertex of the first corner points to the vertex of the second corner opposite thereto are the first direction, the second direction, the third direction, and the fourth direction respectively, and the first direction, the second direction, the third direction, and the fourth direction all intersect with the row direction and the column direction; the plurality of second pixel rows include third sub-pixel rows and fourth sub-pixel rows alternately arranged along the column direction, the third sub-pixel rows include the fifth-type sub-pixels and the sixth-type sub-pixels alternately arranged along the row direction, and the fourth sub-pixel rows include the seventh-type sub-pixels and the eighth-type sub-pixels alternately arranged along the row direction; the plurality of second pixel columns include third sub-pixel columns and fourth sub-pixel columns alternately arranged along the row direction, the third sub-pixel columns include the fifth-type sub-pixels and the seventh-type sub-pixels alternately arranged along the column direction, and the fourth sub-pixel columns include the sixth-type sub-pixels and the eighth-type sub-pixels alternately arranged along the column direction.

[0036] For example, in an embodiment of the present disclosure, the display substrate includes a plurality of first sub-pixel groups, the plurality of first sub-pixel groups are arranged in a plurality of first sub-pixel group rows along the row direction, and adjacent first sub-pixel group rows arranged along the column direction are offset from each other along the row direction, and at least a portion of the first sub-pixel groups is surrounded by an alternating arrangement of the first color sub-pixels and the second color sub-pixels; each first sub-pixel group includes one first color sub-pixel, four second color sub-pixels surrounding the first color sub-pixel, and four third color sub-pixels surrounding the first color sub-pixel, and the four second color sub-pixels and the four third color sub-pixels surrounding the first color sub-pixel are alternately arranged in a circle of sub-pixels; among the third color sub-pixels and the second color sub-pixels, at least one type of color sub-pixel, the corner closest to the first color sub-pixel is the first corner.

[0037] For example, in an embodiment of the present disclosure, in at least a portion of the first sub-pixel groups, all four corners of the first color sub-pixel are the first corners, at least a portion of the four corners of the second color sub-pixels includes two first corners, at least a portion of the four corners of the third color sub-pixels includes one first corner, and the corners of the third color sub-pixels and the second color sub-pixels closest to the first color sub-pixel are the first corners.

[0038] For example, in an embodiment of the present disclosure, the display substrate includes a plurality of second sub-pixel groups, and at least one of the second sub-pixel groups includes a first color sub-pixel and a third color sub-pixel that are arranged adjacent to each other along one of the row direction and the column direction, and two second color sub-pixels that are arranged adjacent to each other along the other of the row direction and the column direction. The center line connecting the centers of the two second color sub-pixels intersects the center line connecting the centers of the other two sub-pixels, and the two second color sub-pixels are symmetrically distributed with respect to the center line connecting the centers of the other two sub-pixels.

[0039] For example, in an embodiment of the present disclosure, in at least one of the second sub-pixel groups, at least one first corner portion is included in the four corner portions of the third color sub-pixel, and the at least one first corner portion includes the corner portion of the third color sub-pixel that is farthest from the first color sub-pixel.

[0040] For example, in an embodiment of the present disclosure, in at least one of the plurality of first pixel rows, the directions in which the vertices of the first corner portion in the third color sub-pixel point to the vertices of the opposite corner portions are all the same; or, in at least one of the plurality of first pixel columns, the directions in which the vertices of the first corner portion in the third color sub-pixel point to the vertices of the opposite corner portions are all the same.

[0041] For example, in an embodiment of the present disclosure, the area of the light-emitting region of at least one blue sub-pixel is greater than the area of the light-emitting region of at least one red sub-pixel, and the area of the light-emitting region of at least one red sub-pixel is greater than the area of the light-emitting region of at least one green sub-pixel.

[0042] For example, in an embodiment of the present disclosure, in at least one of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, the intersection lines of the extension lines of the sides of the light-emitting region form a rhombus, and the diagonal of the rhombus is parallel to at least one of the row direction and the column direction.

[0043] For example, in an embodiment of the present disclosure, in one color sub-pixel of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, the intersection lines of the extension lines of the sides of the light-emitting region form a strip shape, and the long axis of the strip shape intersects both the row direction and the column direction.

[0044] At least one embodiment of the present disclosure provides a display device including the above display substrate. Description of the Drawings

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0060] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second", and the like used in the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0061] Embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes: a plurality of sub-pixels, including a plurality of first-color sub-pixels, a plurality of second-color sub-pixels, and a plurality of third-color sub-pixels. The plurality of first-color sub-pixels and the plurality of third-color sub-pixels are alternately arranged both in the row direction and the column direction to form a plurality of first pixel rows and a plurality of first pixel columns. The plurality of second-color sub-pixels are arranged in an array both in 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 in the column direction and are offset from each other in the row direction. The plurality of first pixel columns and the plurality of second pixel columns are alternately arranged in the row direction and are offset from each other in the column direction. The plurality of sub-pixels include a plurality of light-emitting regions. Each side of each light-emitting region or its extension line is sequentially connected to form a polygon, and there are regions where the plurality of vertices of the polygon of at least some sub-pixels do not overlap with the plurality of corners of the corresponding light-emitting region; among the plurality of corners of the light-emitting region of at least one sub-pixel, at least a first corner is included, and the area of the region where the first corner does not overlap with the vertex of the corresponding polygon is larger than the area of the region where each of at least some other corners does not overlap with the vertex of the corresponding polygon. By providing the first corner in at least one sub-pixel in the embodiments of the present disclosure, it is beneficial to adjust the brightness center in at least some display regions to make its distribution more uniform.

[0062] The following describes the display substrate and the display device provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0063] Figure 1 A partial plan view of the pixel arrangement in the display substrate provided as an example according to the embodiments of the present disclosure. As Figure 1 shown, the display substrate includes a plurality of sub-pixels 100. AsFigure 1 As shown, a plurality of sub-pixels 100 include a plurality of first color sub-pixels 110, a plurality of second color sub-pixels 120, and a plurality of third color sub-pixels 130. The plurality of first color sub-pixels 110 and the plurality of third color sub-pixels 130 are alternately arranged in the row direction (such as the X direction shown in Figure 1 ), to form a first pixel row 01. The plurality of second color sub-pixels 120 are arranged in the row direction to form a second pixel row 02. The first pixel row 01 and the second pixel row 02 are alternately arranged in the column direction (such as the Y direction shown in Figure 1 ) that intersects the row direction and are offset from each other in the row direction. For example, adjacent first color sub-pixel 110 and second color sub-pixel 120 are arranged in a first direction. The first direction intersects both the row direction and the column direction. As shown in Figure 1 , the plurality of first color sub-pixels 110 and the plurality of third color sub-pixels 130 are alternately arranged in the column direction to form a plurality of first pixel columns 03. The plurality of second color sub-pixels 120 are arranged in an array in both 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 plurality of first pixel columns 03 and the plurality of second pixel columns 04 are alternately arranged in the row direction and are offset from each other in the column direction, that is, the second pixel row 02 where a second color sub-pixel 120 is located is between two adjacent first pixel rows 01, and the second pixel column 04 where the second color sub-pixel 120 is located is between two adjacent first pixel columns 03.

[0064] In the embodiments of the present disclosure, both the row direction and the column direction refer to the arrangement direction of the first color sub-pixels and the third color sub-pixels. This direction may be parallel to the direction connecting the geometric centers of the light-emitting regions of two adjacent sub-pixels, or may not be parallel. For example, the row direction intersects the column direction. For example, the included angle between the row direction and the column direction may be 80-100 degrees. For example, the included angle between the row direction and the column direction may be 85-95 degrees. For example, the row direction and the column direction may be perpendicular, but not limited thereto, and may also not be perpendicular. In the embodiments of the present disclosure, the row direction and the column direction may be interchanged.

[0065] As shown in Figure 1As shown, the display substrate includes a plurality of 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 a first-color sub-pixel 110, a third-color sub-pixel 130, and two second-color sub-pixels 120. The first-color sub-pixel 110 and the third-color sub-pixel 130 are shared sub-pixels. Through a virtual algorithm, the four sub-pixels can achieve the display of two virtual pixel units. For example, in the repeating units of the same row, the first-color sub-pixel 110 in the second repeating unit, the third-color sub-pixel 130 in the first repeating unit, and the second-color sub-pixel 120 in the first repeating unit close to the second repeating unit form a virtual pixel unit. At the same time, the first-color sub-pixel 110 in the second repeating unit also forms a virtual pixel unit with the third-color sub-pixel 130 in this repeating unit and the second-color sub-pixel 120 in this repeating unit close to the first repeating unit. In addition, the third-color sub-pixel 130 in the second repeating unit also forms a virtual pixel unit with another second-color sub-pixel 120 in this repeating unit and the first-color sub-pixel 110 in the third repeating unit, thereby effectively improving the resolution of the display substrate.

[0066] The sub-pixels in the embodiments of the present disclosure refer to the light-emitting device structures. The first-color sub-pixel, the second-color sub-pixel, and the third-color sub-pixel are sub-pixels that emit light of different colors. In the embodiments of the present disclosure, the first-color sub-pixel is taken as a red sub-pixel, the second-color sub-pixel is taken as a green sub-pixel, and the third-color sub-pixel is taken as a blue sub-pixel for illustration. However, the first-color sub-pixel being a red sub-pixel, the second-color sub-pixel being a green sub-pixel, and the third-color sub-pixel being a blue sub-pixel do not constitute a limitation on the protection scope of the embodiments of the present disclosure.

[0067] For example, the first-color sub-pixel 110 and the third-color sub-pixel 130 are shared sub-pixels. According to their emission spectra, the areas of both are larger than the area of the second-color sub-pixel 120.

[0068] For example, the area of the light-emitting region of at least one blue sub-pixel is larger than the area of the light-emitting region of at least one red sub-pixel, and the area of the light-emitting region of at least one red sub-pixel is larger than the area of the light-emitting region of at least one green sub-pixel to extend the service life of the display substrate. For example, the areas of the light-emitting regions of the same-color sub-pixels are basically equal.

[0069] Such as Figure 1 As shown, each sub-pixel 100 includes a light-emitting region 101. For example, Figure 2 is Figure 1 a schematic plan view of a partial pixel defining layer corresponding to the pixel structure shown. As Figure 1 and Figure 2As shown, a display substrate is provided with a pixel defining layer 200. The shape of the light-emitting region 101 of each sub-pixel 100 is defined by the opening in the pixel defining layer 200. Thus, the shape of the light-emitting region 101 of each sub-pixel 100 is substantially the same as the shape of the opening in the pixel defining layer 200.

[0070] For example, as Figure 1 and Figure 2 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 opening 201 defines a first light-emitting region 101-1 of the first-color sub-pixel 110. The second opening 202 defines a second light-emitting region 101-2 of the second-color sub-pixel 120. The third opening 203 defines a third light-emitting region 101-3 of the third-color sub-pixel 130.

[0071] For example, the display substrate includes a substrate. Each sub-pixel 100 and the pixel defining layer 200 are disposed on the substrate. Each sub-pixel 100 includes an organic light-emitting element. The organic light-emitting element includes a first electrode, a light-emitting layer, and a second electrode stacked thereon. The second electrode is located on the side of the light-emitting layer facing the substrate. For example, at least a portion of the second electrode is located on the side of the pixel defining layer facing the substrate. When the light-emitting layer is formed in the opening in the pixel defining layer 200 described above, 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, a functional layer is further disposed in at least one of the space between the light-emitting layer and the first electrode and the space between the light-emitting layer and the second electrode. 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.

[0072] An embodiment of the present disclosure schematically shows that the shape of the opening in the pixel defining layer is a figure including rounded corners. Then, the shape of the light-emitting region of each sub-pixel is also a figure including rounded corners. For example, the shape of the second electrode (such as an anode) of each sub-pixel can also be a figure including rounded corners. The figure of the opening in the pixel defining layer may include four straight sides, and at least two adjacent straight sides are connected by a curved segment, and the curved segment forms a rounded corner. However, it is not limited thereto. The figure of the light-emitting region of each sub-pixel may also include three straight sides, five straight sides, or six straight sides. Then, the number of apex angles included in the light-emitting region also changes accordingly.

[0073] For example, the orthographic projection of the opening of the pixel defining layer on the substrate is located within the orthographic projection of the corresponding light-emitting layer on the substrate, that is, the light-emitting layer covers the opening of the pixel defining layer. For example, the area of the light-emitting layer is larger than the area of the corresponding opening of the pixel defining layer, that is, in addition to the part located inside the opening of the pixel defining layer, the light-emitting layer at least further includes a part covering the solid structure of the pixel defining layer. Generally, the light-emitting layer covers the solid structure of the pixel defining layer at each boundary of the opening of the pixel defining layer.

[0074] For example, the light-emitting layers of the first color sub-pixel 110 and the third color sub-pixel 130 adjacent to each other may or may not overlap on the pixel defining layer 200. For example, the light-emitting layers of the first color sub-pixel 110 and the second color sub-pixel 120 adjacent to each other may or may not overlap on the pixel defining layer 200. For example, the light-emitting layers of the second color sub-pixel 120 and the third color sub-pixel 130 adjacent to each other may or may not overlap on the pixel defining layer 200. For example, in the direction parallel to the XY plane, the shortest distance between the vertex of the first corner 1011 and the boundary of the light-emitting layer is less than the shortest distance between the vertices of other top corners and the boundary of the light-emitting layer.

[0075] Figure 3 For Figure 1 a schematic diagram of the shape of a light-emitting region shown. As Figure 1 and Figure 3 shown, each side or its extension line of each light-emitting region 101 is sequentially connected to form a polygon 300, and there is at least a region N0 where multiple top corners 301 of the polygon 300 corresponding to at least some sub-pixels do not overlap with multiple corners 001 of the corresponding light-emitting region 101; among the multiple corners 001 of the light-emitting region 101 of at least one sub-pixel, at least the first corner 1011 is included, and the area of the region N0 where the first corner 1011 does not overlap with the top corner 301 of the corresponding polygon 300 is larger than the area of the region N0 where each of at least some of the other corners 001 does not overlap with the top corner 301 of the polygon 300 corresponding to that corner 001.

[0076] For example, Figure 3 schematically shows that there is a region N0 where all the top corners of the polygon 300 do not overlap with the corresponding corners 001 of the light-emitting region 101, but not limited thereto, and there may also be a region where some top corners of the polygon do not overlap with the corresponding corners of the light-emitting region, and some top corners completely overlap with the corresponding corners of the light-emitting region.

[0077] For example, as Figure 1 and Figure 3As shown, among at least two different color sub-pixels 100 (such as the first color sub-pixel and the second color sub-pixel, or the first color sub-pixel and the third color sub-pixel, or the second color sub-pixel and the third color sub-pixel, or the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel), the shape of the light-emitting region 101 is the shape after at least one first vertex angle 301 of the polygon 300 is truncated. For example, the truncation line 302 for truncating the first vertex angle 301 of the polygon 300 may include line segments with regular shapes such as curves and straight lines, or may be line segments with irregular shapes.

[0078] For example, in the embodiments of the present disclosure, the polygon 300 is schematically shown as a quadrilateral. For example, the shape of the polygon corresponding to at least one color sub-pixel may be a rhombus, a rectangle, or a square, but is not limited thereto. The polygon 300 may also be a triangle, a pentagon, a hexagon, etc. The embodiments of the present disclosure do not limit this. For example, the angles of the vertices of the polygon may be equal or unequal.

[0079] As Figure 1 and Figure 3 As shown, the vertex angle of the light-emitting region 101 includes a first corner 1011. The first corner 1011 is the corner formed after the first vertex angle 301 sandwiched by two first sides 310 of the polygon 300 is truncated. For example, the ratio of the truncated part L1 of at least one of the two first sides 310 to the length of the first side 310 is 0.2 to 0.8. After the first side 310 of the polygon 300 is truncated by the first line segment L1, the remaining part L2 forms the side of the light-emitting region 101 connecting the first corner 1011. For example, both ends of the first corner 1011 are connected to two straight sides of the light-emitting region 101, and at least one of these two straight sides is the straight line side remaining after the first side 310 of the polygon 300 is truncated by the first line segment L1.

[0080] For example, the polygon 300 may be truncated by at least one first vertex angle 301 to form at least one first corner 1011. For example, the degrees of a plurality of first vertex angles 301 included in a polygon 300 are equal, and parameters such as the shape and size of the plurality of first corners 1011 formed after the plurality of first vertex angles 301 are truncated are equal.

[0081] As Figure 1 and Figure 3 As shown, the ratio of the length of the first line segment L1 to the length of the first side 310 is 0.2 to 0.8. For example, the ratio of the length of the first line segment L1 to the length of the first side 310 is 0.3 to 0.7; for example, the ratio of the length of the first line segment L1 to the length of the first side 310 is 0.4 to 0.6; for example, the ratio of the length of the first line segment L1 to the length of the first side 310 is 0.5.

[0082] For example, as Figure 1 andFigure 3 As shown, the ratio of the length of the first line segment L1 to the length of the remaining part L2 is 0.25 to 4. For example, the ratio of the length of the first line segment L1 to the length of the remaining part L2 is 1 to 3. The ratio of the length of the first line segment L1 to the length of the remaining part L2 is 0.5 to 2.

[0083] For example, as Figure 1 and Figure 3 shown, the number of the first corners 1011 in the at least two different color sub-pixels 100 is different. For example, the fact that the number of the first corners 1011 in two different color sub-pixels 100 is different may mean that: the number of the first corners in the same color sub-pixels is the same, and in two different color sub-pixels, the number of the first corners in one sub-pixel is different from the number of the first corners in the other sub-pixel with a different color. For example, the fact that the number of the first corners 1011 in two different color sub-pixels 100 is different may also mean that: the number of the first corners in the same color sub-pixels is the same, the number of different color sub-pixels is different, and then the total number of the first corners included in the different color sub-pixels is different.

[0084] For example, as Figure 1 and Figure 3 shown, the fact that the number of the first corners 1011 in the at least two different color sub-pixels 100 is different is conducive to adjusting the brightness center in at least part of the display area to make its distribution more uniform.

[0085] For example, as Figure 1 shown, the areas of the light-emitting regions 101 of the sub-pixels 100 of the same color are the same, and the areas of the light-emitting regions 101 of the sub-pixels 100 of different colors are different.

[0086] For example, when the light-emitting region 101 includes a first corner 1011, the geometric center of the light-emitting region 101 is located on the side away from the first corner 1011 of the midpoint of the line 303 connecting the vertex of the first apex angle 301 and the vertex of the apex angle opposite to the first corner 1011. Thus, by adjusting the geometric centers of at least part of the light-emitting regions, the brightness center in at least part of the display area can be adjusted to make its distribution more uniform.

[0087] For example, as Figure 1 and Figure 3As shown, in the display substrate provided by the embodiments of the present disclosure, by adjusting the shapes of some sub-pixels, among at least two types of color sub-pixels of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel, the distance from the intersection point of the extension lines of the two straight sides connected to both ends of the first corner to the geometric center of the light-emitting region of this sub-pixel is different from the distance from the intersection point of the two straight sides or their extension lines forming the vertex angle of the light-emitting region opposite to the first corner to the geometric center of the light-emitting region of this sub-pixel, so as to adjust the actual brightness center of each virtual pixel unit, making the distribution of the actual brightness centers in this display substrate more uniform.

[0088] For example, the number of the first corners 1011 in one type of color sub-pixel 100 is one, and the number of the first corners 1011 in another type of color sub-pixel 100 is greater than one, for example, it can be two, three, or four. For example, the number of the first corners 1011 in one type of color sub-pixel 100 can be two, and the number of the first corners 1011 in another type of color sub-pixel 100 can be three or four. For example, the number of the first corners 1011 in one type of color sub-pixel 100 can be three, and the number of the first corners 1011 in another type of color sub-pixel 100 can be four. The embodiments of the present disclosure do not limit the number of the first corners of different color sub-pixels, and can be set according to actual product requirements.

[0089] For example, as Figure 1 and Figure 3 shown, the first corner 1011 includes a vertex P, which can be on the connection line 303. A section of curve (i.e., the outer edge of the first corner) formed by the part where the two sides connected to both ends of the first corner 1011 extend and intersect at its vertex P is used to make the first corner 1011 a rounded chamfer. At this time, the first corner 1011 can be in the range of x micrometers along the contour with the vertex P as the center, and the value of x can be 2 to 7 micrometers. When the first corner is a rounded chamfer and the vertex angle opposite to the first corner in the shape of the light-emitting region is a right angle or an acute angle, the distance from the intersection point of the extension lines of the two straight sides connected to both ends of the first corner to the geometric center O of the light-emitting region 101 is greater than the distance from the intersection point of the extension lines of the two straight sides forming the vertex angle opposite to the first corner to the geometric center O.

[0090] The above-mentioned "round chamfer" is a vertex angle formed by a section of curve, which can be an arc or an irregular curve, such as a curve intercepted from an ellipse, a wavy line, etc. In the embodiments of the present disclosure, it is schematically shown that the curve has a shape convex outward relative to the geometric center O of the light-emitting region 101, but it is not limited thereto. The curve can also have a shape concave inward relative to the geometric center O of the light-emitting region 101. For example, when the curve is an arc convex outward, the range of the central angle of the arc can be 10° to 150°. For example, the range of the central angle of the arc can be 60° to 120°. For example, the central angle of the arc can be 90°. For example, the curve length of the round chamfer included in the first corner portion 1011 can be 10 to 60 micrometers.

[0091] For example, when the first corner portion 1011 is a round chamfer, its radius of curvature can be 5 to 20 micrometers.

[0092] For example, Figure 4A is a schematic diagram of another shape of the light-emitting region. As Figure 4A shown, the above-mentioned first corner portion can also be a line segment formed by the extension and intersection of two sides of a certain vertex angle towards its vertex P (i.e., the outer edge of the first corner portion) so that the vertex angle becomes a flat chamfer. For example, the first corner portion 1011 includes a flat chamfer, and the vertex of the first corner portion can be on the connection line 303, for example, the intersection point of the connection line 303 and the flat chamfer.

[0093] For example, Figure 4B is a schematic diagram of another shape of the light-emitting region. As Figure 4B shown, the shape of the light-emitting region 101 with the first corner portion 1011 can be a sector, and its contour includes two straight sides, the arc of the first corner portion 1011 connecting the two straight sides, and the vertex of the second corner portion 1012 formed by the intersection of the two straight sides (or the arc of the second corner portion 1012 connecting the two straight sides).

[0094] For example, as Figures 1 to 4A shown, the outer edge shape of the first corner portion 1011 includes a line segment, and the ratio of the lengths of the outer edges of the first corner portion 1011 in different color sub-pixels 100 is 0.8 to 1.2. For example, the ratio of the lengths of the outer edges of the first corner portion 1011 in at least two color sub-pixels 100 is 0.9 to 1.1. For example, the lengths of the outer edges of the first corner portion 1011 in at least two color sub-pixels 100 are substantially equal. For example, in at least two color sub-pixels 100, the included angle between the first corner portion 1011 and the connection line 303 is the same.

[0095] For example, as Figures 1 to 4AAs shown, the shape of the outer edge of the first corner portion 1011 includes an arc, and the ratio of the radian of the outer edge of the first corner portion 1011 in different color sub-pixels 100 is 0.8 to 1.2. For example, the ratio of the radian of the outer edge of the first corner portion 1011 in at least two color sub-pixels 100 is 0.9 to 1.1. For example, the radian of the outer edge of the first corner portion 1011 in at least two color sub-pixels 100 is substantially equal.

[0096] For example, in at least one color sub-pixel 100, the lengths of the two sides of the light-emitting region 101 connecting the two end points of the first corner portion 1011 are substantially equal.

[0097] For example, as Figure 1 shown, the light-emitting regions 101 of the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 all include a first corner portion 1011, and the number of first corner portions 1011 in different color sub-pixels 100 is different.

[0098] In the embodiments of the present disclosure, the shape (including parameters such as length and curvature) and the number of the first corner portions in the same color sub-pixel are the same, and the shape of the first corner portions in different color sub-pixels is the same as an example for description, but is not limited thereto. The shapes of the first corner portions in different color sub-pixels may be the same or different.

[0099] For example, as Figure 1 shown, the first color sub-pixel 110 includes four first corner portions 1011, the second color sub-pixel 120 includes two first corner portions 1011, and the third color sub-pixel 130 includes one first corner portion 1011.

[0100] For example, as Figures 1 to 4A shown, in at least one of the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130, the top corner of the light-emitting region 101 further includes a second corner portion 1012, and the distance from the intersection point of the two sides or their extension lines connecting the two end points of the first corner portion 1011 (i.e., the vertex of the first top corner 301) to the geometric center O of the light-emitting region 101 of the sub-pixel 100 is greater than the distance from the intersection point of the two sides or their extension lines forming the second corner portion 1012 to the geometric center O. The above-mentioned "two sides forming the second corner portion 1012" may mean that these two sides intersect to form the second corner portion, or may mean that these two sides are connected to the two ends of the second corner portion.

[0101] For example, as Figures 1 to 4A shown, the second corner portion 1012 may be the corner portion of the polygon 300 without cutting off the top corner, that is, the second corner portion 1012 may be a top corner of the polygon 300, and this top corner may be opposite to the first corner portion 1011 or adjacent to the first corner portion 1011.

[0102] For example, as Figures 1 to 4A shown, the second corner 1012 can be a corner formed after the polygon 300 has its second apex angle 304, which is clamped by two second sides 320, or its second apex angle 304, which is clamped by one of the first sides 310 and one second side 320, cut off. The ratio of the cut-off part L3 of at least one of the first side 310 and the second side 320 to this side is 0.05 to 0.2. After the second side 320 of the polygon 300 has its second line segment L3 cut off, a side (i.e., the remaining part L4) of the light-emitting region 101 connecting the second corner 1012 is formed. The ratio of the length of the second line segment L3 to the length of this side is 0.05 to 0.2. For example, the ratio of the length of the second line segment L3 to the length of this side is 0.08 to 0.18. For example, the ratio of the length of the second line segment L3 to the length of this side is 0.1 to 0.15.

[0103] For example, the ratio of the length of the second line segment L3 to the length of the remaining part L4 is 0.05 to 0.3. For example, the ratio of the length of the second line segment L3 to the length of the remaining part L4 is 0.1 to 0.2.

[0104] For example, as Figures 1 to 4A shown, the lengths of the first side 310 and the second side 320 can be the same. If the length of the first line segment L1 is greater than the length of the second line segment L3, then the curvature (or arc radian or length) of the first corner 1011 is greater than the curvature (or arc radian or length) of the second corner 1012.

[0105] For example, as Figures 1 to 4A shown, the shape of the outer edge of the second corner 1012 includes a line segment. The ratio of the lengths of the outer edges of the second corner 1012 in different color sub-pixels 100 is 0.8 to 1.2. For example, the ratio of the lengths of the outer edges of the second corner 1012 in at least two color sub-pixels 100 is 0.9 to 1.1. For example, the lengths of the outer edges of the second corner 1012 in at least two color sub-pixels 100 are approximately equal. For example, in at least two color sub-pixels 100, the angle between the second corner 1012 and the line connecting this second corner 1012 and the vertex of its opposite apex angle is the same.

[0106] For example, as Figures 1 to 4A shown, the shape of the outer edge of the second corner 1012 includes an arc. The ratio of the arc radians of the outer edges of the second corner 1012 in different color sub-pixels 100 is 0.8 to 1.2. For example, the ratio of the arc radians of the outer edges of the second corner 1012 in at least two color sub-pixels 100 is 0.9 to 1.1. For example, the arc radians of the outer edges of the second corner 1012 in at least two color sub-pixels 100 are approximately equal.

[0107] For example, in at least one color sub-pixel 100, the lengths of two sides of the light-emitting region 101 connecting the two end points of the same second corner 1012 are substantially equal.

[0108] In the embodiments of the present disclosure, the shape (including parameters such as length and curvature) and the number of the second corners in the same color sub-pixel are the same, and the shape of the second corners in different color sub-pixels is taken as an example to be the same, but it is not limited thereto. The shape of the second corners in different color sub-pixels may be the same or different.

[0109] For example, as Figures 1 to 4A shown, among the vertex angles of at least part of the light-emitting region 101, the vertex angles other than the first corner 1011 are all second corners 1012, and the multiple vertex angles in at least part of the light-emitting region 101 only include the first vertex angle 1011 and the second vertex angle 1012.

[0110] For example, as Figures 1 to 4A shown, in at least one of the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130, the connecting lines of the intersection points of the extension lines of each side of the light-emitting region 101 form a rhombus, and the diagonals of the rhombus are parallel to at least one of the row direction and the column direction. The connecting lines of the intersection points of the extension lines of each side of the above-mentioned light-emitting region 101 form the above-mentioned polygon.

[0111] For example, as Figures 1 to 4A shown, in one color sub-pixel among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130, the connecting lines of the intersection points of the extension lines of each side of the light-emitting region 100 form an elongated shape, such as a rectangle, and the long axis of the elongated shape intersects both the row direction and the column direction.

[0112] For example, the included angle between the long axis of the elongated shape and the row direction may be 20 - 60 degrees. For example, the included angle between the long axis of the elongated shape and the row direction may be 30 - 50 degrees.

[0113] For example, Figure 1 schematically shows that each light-emitting region 101 includes four corners. The shapes of the polygons corresponding to the first color sub-pixel 110 and the third color sub-pixel 130 are rhombuses or squares, and the shape of the polygon corresponding to the second color sub-pixel 120 is a rectangle. For example, the first color sub-pixel 110 includes four first corners 1011; the second color sub-pixel 120 includes two first corners 1011 and two second corners 1012. In the second color sub-pixel 120, the arc radian of the first corner 1011 is greater than the arc radian of the second corner 1012; the third color sub-pixel 130 includes one first corner 1011 and three second corners 1012, and the arc radian of the first corner 1011 is greater than the arc radian of the second corner 1012, but the embodiments of the present disclosure are not limited thereto.

[0114] For example, as Figure 1 shown, two first corners 1011 in the second color sub-pixel 120 are adjacent apex angles, and the side between the two adjacent first corners 1011 is the short side of the light-emitting region. The embodiments of the present disclosure are not limited thereto, and the side between two adjacent first corners may also be the long side of the light-emitting region.

[0115] For example, two adjacent apex angles of the light-emitting region 101 of at least one sub-pixel 100 are first corners 1101. A line segment may connect the endpoints of the two adjacent first corners 1011 that are close to each other, or the endpoints of the two adjacent first corners 1011 that are close to each other coincide, that is, the distance between the two endpoints is 0. The embodiments of the present disclosure do not limit this.

[0116] For example, two adjacent apex angles of the light-emitting region 101 of at least one sub-pixel 100 are second corners 1102. A line segment may connect the endpoints of the two adjacent second corners 1102 that are close to each other.

[0117] For example, two adjacent apex angles of the light-emitting region 101 of at least one sub-pixel 100 include a first corner 1011 and a second corner 1012. A line segment may connect the adjacent first corner 1011 and the second corner 1012, or the endpoints of the adjacent first corner 1011 and the second corner 1012 that are close to each other coincide, that is, the distance between the two endpoints is 0. The embodiments of the present disclosure do not limit this.

[0118] For example, at least part of the light-emitting region 101 includes four corners. Among the four corners of one color sub-pixel in the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130, there are two, three, or four first corners 1101. Among the four corners of at least one of the other two color sub-pixels in the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130, there is one first corner 1101.

[0119] For example, as Figure 1 shown, the third color sub-pixel 130 includes one first corner 1101, and both the second color sub-pixel 120 and the first color sub-pixel 110 include at least two first corners 1101. Of course, the embodiments of the present disclosure do not limit the color of the sub-pixel including one first corner, which may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel; the embodiments of the present disclosure do not limit the color of the sub-pixel including at least two first corners, which may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel.

[0120] For example, all four corners of one type of color sub-pixel among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 are the first corners 1101, four corners of another type of color sub-pixel among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 include two first corners 1101, and four corners of the other color sub-pixel among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 include one first corner 1101.

[0121] For example, as Figure 1 shown, all four corners of the first color sub-pixel 110 are the first corners 1101, four corners of the second color sub-pixel 120 include two first corners 1101, and four corners of the third color sub-pixel 130 include one first corner 1101. Of course, embodiments of the present disclosure do not limit the color of the sub-pixel including one first corner, which may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel; embodiments of the present disclosure do not limit the color of the sub-pixel including two first corners, which may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel; embodiments of the present disclosure do not limit the color of the sub-pixel including four first corners, which may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel.

[0122] For example, four corners of two types of color sub-pixels among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 include one first corner 1101, and four corners of the other color sub-pixel among the first color sub-pixel 110, the second color sub-pixel 120, and the third color sub-pixel 130 include three first corners 1101.

[0123] For example, as Figure 1 shown, a sub-pixel 100 includes the first corner 1011, another color sub-pixel 100 adjacent to the sub-pixel 100 in at least one of the row direction and the column direction does not include the first corner 1011, or all vertex angles included in the light-emitting region 101 of the other color sub-pixel 100 are the first corners 1011, and a connecting line CL between the geometric centers of the light-emitting regions 101 of the sub-pixel and the other color sub-pixel adjacent thereto is not parallel to both the row direction and the column direction.

[0124] For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 45°. For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 30°. For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 20°. For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 15°. For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 10°. For example, the angle between the connection line CL of the geometric centers and one of the row direction and the column direction is less than 5°.

[0125] For example, at least some of the sub-pixels further include pixel circuits ( Figure 7A and Figure 7B the pixel circuit 700 as shown), and the pixel circuit is configured to be connected to the light-emitting element to drive the light-emitting element to emit light. Some sub-pixels are provided in at least some areas of the display substrate, and the pixel circuits of these sub-pixels are arranged in an array in the row direction and the column direction. The sub-pixels driven to emit light by the same row of pixel circuits are the sub-pixels located in the same row (including the first-color sub-pixels and the third-color sub-pixels located in the same row, or the second-color sub-pixels located in the same row), and the sub-pixels driven to emit light by the same column of pixel circuits are the sub-pixels located in the same column.

[0126] For example, the display substrate further includes a plurality of gate lines extending in the row direction and arranged in the column direction, and the sub-pixels controlled by the same gate line are the sub-pixels located in the same row.

[0127] For example, the light-emitting regions of the first-color sub-pixels and the second-color sub-pixels arranged in the row direction can be penetrated by a straight line extending in the row direction, and this straight line can penetrate the geometric centers of the light-emitting regions of at least some of the sub-pixels. For example, the light-emitting region of the second-color sub-pixels arranged in the row direction can also be penetrated by a straight line extending in the row direction, and this straight line can penetrate the light-emitting regions of at least some of the sub-pixels. Similarly, the light-emitting regions of a column of sub-pixels arranged in the column direction can be penetrated by a straight line extending in the column direction, and this straight line can penetrate the geometric centers of the light-emitting regions of at least some of the sub-pixels.

[0128] For example, as Figure 1As shown, the above-mentioned "one sub-pixel" may be the third color sub-pixel 130, and the above-mentioned "another color sub-pixel" may be the first color sub-pixel 120. The third color sub-pixel 130 includes a first corner 1011. The top corners of the light-emitting region 101 of the first color sub-pixel 110 are all the first corner 1011. Since a first corner 1011 is provided in the third color sub-pixel 130, the geometric center of the light-emitting region of this sub-pixel is offset in a direction away from the first corner 1011 compared to when the first corner 1011 is not provided. And the top corners of the first color sub-pixel 110 are all the first corner 1011, and the geometric center of its light-emitting region is not offset compared to the case where the first corner 1011 is not provided. Then, the connection line of the geometric centers of these two color sub-pixels arranged in one of the row direction and the column direction is no longer a straight line but a broken line. Of course, in the embodiments of the present disclosure, it is not limited that the "one sub-pixel" is the third color sub-pixel, and it may also be the first color sub-pixel. Correspondingly, the above-mentioned "another color sub-pixel" is the first color sub-pixel.

[0129] For example, as Figure 1 shown, the number of first corners included in the above-mentioned "one sub-pixel" may be multiple, but they cannot all be located at opposite corners. That is, when the above-mentioned "one sub-pixel" including the first corner is compared with the case where the first corner is not provided in this sub-pixel, the geometric center of its light-emitting region is offset. For example, its geometric center is offset in a direction away from the first corner.

[0130] For example, Figure 4C is Figure 1 a schematic diagram of the light-emitting regions of some sub-pixels shown. As Figure 4C shown, each side or its extension line of the light-emitting region of the first color sub-pixel 110 is sequentially connected to form a first polygon 300-1, each side or its extension line of the second color sub-pixel 120 is sequentially connected to form a second polygon 300-2, and each side or its extension line of the light-emitting region of the third color sub-pixel 130 is sequentially connected to form a third polygon 300-3. At least two of the first polygon 300-1, the second polygon 300-2, and the third polygon 300-3 are similar figures. For example, the first polygon 300-1 and the third polygon 300-3 are similar figures. The embodiments of the present disclosure are not limited to this, and it may also be that the first polygon and the second polygon are similar figures; or the second polygon and the third polygon are similar figures; or all three are similar figures.

[0131] For example, as Figure 1 and Figure 4C shown, in the same sub-pixel 100, the shortest distance d11 between the two straight sides SL connecting the two ends of the first corner 1011 is not greater than the length of the connection line L between the vertices of the two corners adjacent to the first corner 1011 in this sub-pixel 100.

[0132] For example, as Figure 1 and Figure 4C shown, the lengths of the two straight edges SL connecting both ends of the first corner 1011 are not less than 3 micrometers. For example, the lengths of the two straight edges SL connecting both ends of the first corner 1011 are not less than 4 micrometers. The lengths of the two straight edges SL connecting both ends of the first corner 1011 are not less than 5 micrometers.

[0133] For example, as Figure 1 and Figure 4C shown, the light-emitting region 101 of at least one sub-pixel 100 having the first corner 1011 is an axisymmetric figure, and at least one axis of symmetry AS in the axisymmetric figure coincides with the angular bisector AB of the first corner 1011.

[0134] Figure 5 is a partial plan view of the pixel arrangement in the display substrate provided for another example according to an embodiment of the present disclosure. As Figure 5 shown, the third color sub-pixel 130 and the second color sub-pixel 120 both include a first corner 1101, and the first color sub-pixel 110 includes three first corners 1101. Of course, the embodiment of the present disclosure does not limit the color of the sub-pixel including one first corner, which can be a red sub-pixel, a green sub-pixel, or a blue sub-pixel; the embodiment of the present disclosure does not limit the color of the sub-pixel including three first corners, which can be a red sub-pixel, a green sub-pixel, or a blue sub-pixel.

[0135] For example, as Figure 5 shown, the second corner 1012 in each sub-pixel 100 can be a vertex angle formed by the intersection of two adjacent straight edges, or can be a rounded chamfer or a straight chamfer, and the embodiment of the present disclosure does not limit this. For example, as Figure 5 shown, the shapes of the second corners 1012 in different color sub-pixels can be the same or different.

[0136] When the number of vertex angles in each light-emitting region is four, the embodiment of the present disclosure does not limit the number of first corners included in different color sub-pixels. The number of first corners included in the three color sub-pixels can all be different, and this number can be selected from 1 - 4; it can also be that the number of first corners included in two color sub-pixels is the same, and the number of first corners included in the third color sub-pixel is different. Then the number of first corners included in the two color sub-pixels can be selected from 1 - 4, and the number of first corners included in the third color sub-pixel can be selected as another one from 1 - 4; it can also be that only two color sub-pixels include first corners, and the number of first corners included in different color sub-pixels can be selected from 1 - 4, and the embodiment of the present disclosure can be set according to the needs of the product.

[0137] Of course, the embodiments of the present disclosure are not limited to the number of apex angles of each light-emitting region being four, and may also be three or greater than four. At this time, the number of the first corner portions in the sub-pixels may be set according to the above rules.

[0138] For example, in at least one of the first color sub-pixels 110, the second color sub-pixels 120, and the third color sub-pixels 130, each light-emitting region 101 includes a first corner portion 1011 and a second corner portion 1012, and the second corner portion 1012 includes an apex angle opposite to the first corner portion 1011. The at least one of the color sub-pixels includes the same type of sub-pixels. In this type of sub-pixels, the directions from the vertices of the first corner portions 1011 to the vertices of the second corner portions 1012 opposite thereto are all the same.

[0139] For example, Figure 6A is a partial plan view of the pixel arrangement in the display substrate provided for an example according to the embodiments of the present disclosure. As Figure 6A shown, the third color sub-pixels 130 include the same type of sub-pixels. In this type of sub-pixels, the direction D1 from the vertex of the first corner portion 1011 to the vertex of the second corner portion 1012 opposite thereto is all opposite to the direction indicated by the arrow in the X direction. For example, the direction D1 points to the left and the first corner portion 1011 faces to the right. For example, when a column of the first color sub-pixels 110 and a column of the second color sub-pixels 120 arranged adjacent to each other in the Y direction emit light, it is easy to form a wavy line. By setting the first corner portions 1011 of the third color sub-pixels 130 to all face to the right, the brightness center can be adjusted, the sawtooth phenomenon can be weakened, which is beneficial to improving the display effect of the display substrate.

[0140] The embodiments of the present disclosure are not limited thereto. In this same type of sub-pixels, the directions from the vertices of the first corner portions to the vertices of the second corner portions opposite thereto may also be all the same as the direction indicated by the arrow in the X direction. For example, the direction D1 points to the right and the first corner portion faces to the left; or, in this same type of sub-pixels, the directions from the vertices of the first corner portions to the vertices of the second corner portions opposite thereto may also be all the same as the direction indicated by the arrow in the Y direction. For example, the direction D1 points upward and the first corner portion faces downward; or, in this same type of sub-pixels, the directions from the vertices of the first corner portions to the vertices of the second corner portions opposite thereto may also be all opposite to the direction indicated by the arrow in the Y direction. For example, the direction D1 points downward and the first corner portion faces upward. For example, when a row of the first color sub-pixels 110 and a row of the second color sub-pixels 120 arranged adjacent to each other in the X direction emit light, it is easy to form a wavy line. By setting the first corner portions 1011 of the third color sub-pixels 130 to all face upward or downward, the brightness center can be adjusted, the sawtooth phenomenon can be weakened, which is beneficial to improving the display effect of the display substrate.

[0141] For example, asFigure 6A As shown, the direction in which the vertex of the first corner 1011 of this type of sub-pixel in the third color sub-pixel 130 points to the vertex of the second corner 1012 opposite thereto may be parallel to the row direction or the column direction.

[0142] The embodiments of the present disclosure are not limited to the same orientation of the first corners of the third color sub-pixels in each row or each column. For example, in at least one of the multiple first pixel rows, the orientations of the first corners 1011 in the third color sub-pixels 130 are the same; or, in at least one of the multiple first pixel columns, the orientations of the first corners 1011 in the third color sub-pixels 130 are the same. For example, the orientations of the first corners 1011 of the third color sub-pixels 130 located in different first pixel rows (or different first pixel columns) may be the same or different, and can be set according to actual product requirements.

[0143] The embodiments of the present disclosure are not limited to all the first corners in the third color sub-pixels facing the same direction. For example, it is also possible that all the first corners in the second color sub-pixels face the same direction, or all the first corners in the first color sub-pixels face the same direction, or all the first corners in at least two color sub-pixels face the same direction.

[0144] For example, as Figure 6A shown, the display substrate includes a plurality of sub-pixel groups 2000. At least one sub-pixel group 2000 includes a first color sub-pixel 110 and a third color sub-pixel 130 that are arranged adjacent to each other along one of the row direction and the column direction, and two second color sub-pixels 120 that are arranged adjacent to each other along the other of the row direction and the column direction. The center connection line of the two second color sub-pixels 120 intersects the center connection line of the other two sub-pixels, and the two second color sub-pixels 120 are symmetrically distributed with respect to the center connection line of the other two sub-pixels. For example, the second color sub-pixel 120 is a green sub-pixel, and the two second color sub-pixels 120 in the sub-pixel group 2000 are symmetrically distributed, which is beneficial to improving the uniformity of the distribution of green sub-pixels on the display substrate.

[0145] For example, as Figure 6A shown, in at least one second sub-pixel group 2000, the four corners of the third color sub-pixel 130 include at least one first corner 1011, and at least one first corner 1011 includes the top corner of the third color sub-pixel 130 that is farthest from the first color sub-pixel 110, which is beneficial to adjusting the center of the third color sub-pixel 130 to be close to the first color sub-pixel 110 and improving the brightness uniformity of the display substrate.

[0146] For example, Figure 6ASchematically shown, in each sub-pixel group 2000, the third-color sub-pixel 130 includes a first corner 1011, and the first corner 1011 is the vertex angle of the third-color sub-pixel 130 that is farthest from the first-color sub-pixel 110 adjacent to it in the row direction, that is, the first corner 1011 faces right or left.

[0147] The embodiments of the present disclosure are not limited thereto. For example, the first corners of the third-color sub-pixels may also all face upward or all face downward, so that the first corners of the third-color sub-pixels are located away from the first-color sub-pixels adjacent to the third-color sub-pixels in the column direction to adjust the brightness center.

[0148] For example, in at least one sub-pixel group 2000, when the third-color sub-pixel 130 includes multiple first corners 1011, the first corner 1011 may be any vertex angle other than the vertex angle closest to the first-color sub-pixel 110.

[0149] For example, Figure 6B is a schematic diagram of a sub-pixel group provided according to an embodiment of the present disclosure. As Figure 6B shown, in at least one sub-pixel group 2000, the first-color sub-pixel 110 may also include at least one first corner 1011, and the at least one first corner 1011 may include the vertex angle farthest from the third-color sub-pixel 130, which is beneficial to adjusting the brightness center.

[0150] For example, as Figure 6B shown, in at least one sub-pixel group 2000, the second-color sub-pixel 120 may include at least one first corner 1011, and the position and number of the first corner 1011 may be set according to the brightness requirement of the display substrate. For example, the first corner 1011 in the second-color sub-pixel 120 is set on the side facing the first-color sub-pixel 110, or may be set on the side facing the third-color sub-pixel 130, or may also be set on the side away from the first-color sub-pixel 110 and away from the third-color sub-pixel 130. For example, the second-color sub-pixel 120 may be provided with two first corners 1011, and the two first corners 1011 are two adjacent vertex angles of the light-emitting region. For example, the second-color sub-pixel 120 may also be provided with three first corners 1011 or four first corners 1011.

[0151] For example, at least one of the first-color sub-pixel 110, the second-color sub-pixel 120, and the third-color sub-pixel 130 includes at least two types of sub-pixels. In different types of sub-pixels, the direction in which the vertex of the first corner 1011 points to the vertex of the second corner 1012 opposite to it is different.

[0152] In the embodiments of the present disclosure, different types of sub-pixels refer to sub-pixels in which the direction from the vertex of the first corner to the vertex of the second corner opposite thereto is different. For example, the above-mentioned sub-pixels may include one first corner and three second corners, and one of the three second corners is opposite to one first corner; the above-mentioned sub-pixels may also include two first corners and two second corners, and each first corner is opposite to a corresponding second corner. At this time, the two first corners are adjacent apexes, and one of the first corners is used as the reference first corner for determining different types of sub-pixels according to the relative position relationship between the two first corners, and the direction from the reference first corner to the second corner opposite thereto is used as the reference direction; the above-mentioned sub-pixels may also include three first corners and one second corner, and the first corner opposite to the second corner is used as the reference first corner to determine different types of sub-pixels, and the direction from the reference first corner to the second corner opposite thereto is used as the reference direction.

[0153] For example, as Figure 6B shown, in the light-emitting region of at least one color sub-pixel, the connection line L between the vertices of the other two apexes except the above-mentioned reference first corner and the second corner opposite thereto divides the light-emitting region into two parts, one part is the part where the first corner is located, and the other part is the part where the second corner is located. For example, in the same sub-pixel, the connection line L between the vertices of the two corners adjacent to the first corner 1011 divides the sub-pixel into two parts, and the areas of the two parts are different.

[0154] For example, the area ratio of the two parts is 0.1-10. For example, the area ratio of the two parts is 0.2-9. For example, the area ratio of the two parts is 0.3-8. For example, the area ratio of the two parts is 0.4-7. For example, the area ratio of the two parts is 0.5-6. For example, the area ratio of the two parts is 0.7-5.

[0155] For example, the ratio of the area of the part where the first corner 1011 is located to the area of the part where the second corner 1012 is located may be 0.1 to 0.99. For example, the ratio of the area of the part where the first corner 1011 is located to the area of the part where the second corner 1012 is located may be 0.2 to 0.9. For example, the ratio of the area of the part where the first corner 1011 is located to the area of the part where the second corner 1012 is located may be 0.3 to 0.8. For example, the ratio of the area of the part where the first corner 1011 is located to the area of the part where the second corner 1012 is located may be 0.4 to 0.7.

[0156] For example, as Figure 6BAs shown, the distance d1 between the vertex of the first corner portion 1011 and the connection line L is less than the distance d2 between the vertex of the second corner portion 1012 and the connection line L. For example, the ratio d1 / d2 of the distance d1 between the vertex of the first corner portion 1011 and the connection line L to the distance d2 between the vertex of the second corner portion 1012 and the connection line L can range from 0.1 to 0.9. For example, the range of d1 / d2 can be from 0.2 to 0.8. For example, the range of d1 / d2 can be from 0.4 to 0.6. For example, the range of the ratio of d1 to d2 can be from 0.7 to 0.9.

[0157] For example, as Figure 6B shown, the length of the connection line between the vertex of the first corner portion 1011 and the vertex of the second corner portion 1012 can be a (i.e., the sum of the above-mentioned distance d1 and distance d2), the length of the connection line L can be b, and the range of the ratio of a to b can be from 0.6 to 0.9. For example, the range of the ratio of a to b can be from 0.7 to 0.8.

[0158] In a general display substrate, the shapes and areas of the two parts where the two opposite top corners of each sub-pixel are located are the same. Compared with such a display substrate, 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 in-screen fingerprint function or an in-screen camera function by reducing the area of the part where the first corner is located.

[0159] For example, Figure 7A is an arrangement diagram of another sub-pixel group 2000. As Figure 7A shown, the third color sub-pixel 130 includes the first corner portion 1011, and the connection line L between the two corner vertices adjacent to the first corner portion 1011 of the third color sub-pixel 130 divides the third color sub-pixel 130 into a first part 131 and a second part 132. The first part 131 includes the first corner portion 1011, and the area of the first part 131 is smaller than the area of the second part 132.

[0160] For example, as Figure 7A shown, the luminous efficiency of the third color sub-pixel 130 is less than the luminous efficiency of the second color sub-pixel 120, and the second part 131 of the third color sub-pixel 130 is closer to the second color sub-pixel 120 that is driven in the same row as the third color sub-pixel 130 and adjacent to the third color sub-pixel 130.

[0161] For example, Figure 7A the sub-pixels in Figure 7B include a pixel circuit 700, Figure 7A is an equivalent diagram of the pixel circuit diagram shown in Figure 7A and Figure 7BAs shown, the pixel circuit 700 includes a second reset transistor T1, a second light-emitting control transistor T5, a first light-emitting control transistor T6, a data writing transistor T4, a driving transistor T3, a threshold compensation transistor T2, a first reset control transistor T7, and a storage capacitor C. For example, the display substrate further includes a scan signal line 043, a reset control signal line 044, and a light-emitting control signal line 045 extending in the row direction, and a data line 910 extending in the column direction.

[0162] For example, a first pole of the threshold compensation transistor T2 is connected to a first pole of the driving transistor T3, and a second pole of the threshold compensation transistor T2 is connected to a gate of the driving transistor T3; a first pole of the first reset control transistor T7 is connected to a reset power signal line to receive a reset signal Vinit, and a second pole of the first reset control transistor T7 is connected to a second electrode of the light-emitting element; a first pole of the data writing transistor T4 is connected to a second pole of the driving transistor T3, a second pole of the data writing transistor T4 is connected to the data line to receive a data signal Data, and a gate of the data writing transistor T4 is electrically connected to the scan signal line to receive a scan signal Gate; a first pole of the storage capacitor C is electrically connected to the power signal line, and a second pole of the storage capacitor C is electrically connected to the gate of the driving transistor T3; a gate of the threshold compensation transistor T2 is electrically connected to the scan signal line to receive a compensation control signal; a gate of the first reset control transistor T7 is electrically connected to the reset control signal line to receive a reset control signal Reset(N+1); a first pole of the second reset transistor T1 is electrically connected to the reset power signal line to receive the reset signal Vinit, a second pole of the second reset transistor T1 is connected to the gate of the driving transistor T3, and a gate of the second reset transistor T1 is electrically connected to the reset control signal line to receive a reset control signal Reset(N); a gate of the first light-emitting control transistor T6 is electrically connected to the light-emitting control signal line to receive a light-emitting control signal EM; a first pole of the second light-emitting control transistor T5 is electrically connected to the power signal line to receive a first power signal VDD, a second pole of the second light-emitting control transistor T5 is electrically connected to a second pole of the driving transistor T3, a gate of the second light-emitting control transistor T5 is electrically connected to the light-emitting control signal line to receive the light-emitting control signal EM, and a first electrode of the light-emitting element is connected to a voltage terminal VSS. The above-mentioned power signal line refers to a signal line for outputting a voltage signal VDD, and can be connected to a voltage source to output a constant voltage signal, such as a positive voltage signal.

[0163] It should be noted that in the embodiments of the present disclosure, in addition to the pixel circuit can be Figure 7B the 7T1C (i.e., seven transistors and one capacitor) structure shown, it can also be a structure including other numbers of transistors, such as 7T2C structure, 6T1C structure, 6T2C structure, or 9T2C structure. The embodiments of the present disclosure do not limit this.

[0164] For example, as Figure 7A shown, in the sub-pixel group 2000, the pixel circuits 700 of one third-color sub-pixel 130 and the pixel circuits 700 of two second-color sub-pixels 120 are located in the same row. For example, the above three pixel circuits 700 are controlled by the same scanning signal line 043. For example, in the sub-pixel group 2000, the pixel circuit 700 of the first-color sub-pixel 110 is located in a different row from the above three pixel circuits 700, that is, the pixel circuit 700 of the first-color sub-pixel 110 and the pixel circuits 700 of the two second-color sub-pixels 120 are controlled by two scanning signal lines 043.

[0165] Figure 8 A partial plan view of the pixel arrangement in the display substrate provided for an example according to an embodiment of the present disclosure. As Figure 8 shown, the above at least one type of color sub-pixel includes two types of sub-pixels. In one type of sub-pixel, the direction from the vertex of the first corner 1011 to the vertex of the second corner 1012 opposite thereto is D2; in the other type of sub-pixel, the direction from the vertex of the first corner 1011 to the vertex of the second corner 1012 opposite thereto is D3, and the two directions are different.

[0166] For example, as Figure 8 shown, the direction D2 and the direction D3 may be parallel and opposite, but are not limited thereto, and the two directions may also intersect.

[0167] For example, as Figure 8 shown, the third-color sub-pixel 130 includes two different types of sub-pixels. In one type of sub-pixel, the first corner 1011 faces upward, and in the other type of sub-pixel, the first corner 1011 faces downward.

[0168] The embodiment of the present disclosure is not limited thereto. For example, in the two different types of sub-pixels in the third-color sub-pixel, the orientations of the first corners may also be left and right respectively, or up and left, or up and right, or down and right, or down and left.

[0169] Of course, the embodiment of the present disclosure is not limited to the third-color sub-pixel including two different types. At least one of the first-color sub-pixel and the second-color sub-pixel may also include two different types of sub-pixels, and the judgment criteria for different types of sub-pixels in the same color sub-pixel may refer to the judgment criteria for different types of sub-pixels in the above third-color sub-pixel.

[0170] For example, in the same color sub-pixel having different types of sub-pixels 100, two adjacent sub-pixels 100 in at least one of the row direction and the column direction are different types of sub-pixels.

[0171] For example, as Figure 8As shown, the orientations of the first corner portions 1011 of two adjacent third color sub-pixels 130 arranged in the row direction are different. For example, they are respectively upward and downward, but not limited thereto. They can also be respectively leftward and rightward, or upward and leftward, or upward and rightward, or downward and rightward, or downward and leftward.

[0172] For example, as Figure 8 shown, the orientations of the first corner portions 1011 of two adjacent third color sub-pixels 130 arranged in the column direction are different. For example, they are respectively upward and downward, but not limited thereto. They can also be respectively leftward and rightward, or upward and leftward, or upward and rightward, or downward and rightward, or downward and leftward.

[0173] The embodiments of the present disclosure are not limited thereto. The above at least one type of color sub-pixel may further include three types of sub-pixels. The orientations of the first corner portions of the three different types of sub-pixels may include any three of upward, downward, leftward, and rightward. And the sub-pixels located in the same row (or the same column) may include sub-pixels of the same type, or may include at least two types of sub-pixels. Two adjacent sub-pixels in at least one of the row direction and the column direction may be sub-pixels of the same type, or may be sub-pixels of different types, and can be set according to the actual product requirements. For example, one type of color sub-pixel may include the above three types of sub-pixels, each of the two types of color sub-pixels may include the above three types of sub-pixels, or each of the three types of color sub-pixels may include the above three types of sub-pixels. The embodiments of the present disclosure do not limit this.

[0174] For example, as Figure 1 shown, the above at least one type of color sub-pixel includes four different types of sub-pixels, such as the first type of sub-pixel 1001, the second type of sub-pixel 1002, the third type of sub-pixel 1003, and the fourth type of sub-pixel 1004. Among different types of sub-pixels, the direction from the vertex of the first corner portion 1011 to the vertex of the second corner portion 1012 is different. For example, the positions of the first corner portions 1011 in different types of sub-pixels 100 are different. For example, the orientations of the first corner portions 1011 in different types of sub-pixels 100 are different.

[0175] For example, the shapes of the sub-pixels 100 of each type are the same, or the areas are the same. For example, the shapes and areas of the sub-pixels 100 of each type are both the same. For example, the numbers of different types of sub-pixels 100 are approximately the same. For example, among the first type of sub-pixels 1001, the second type of sub-pixels 1002, the third type of sub-pixels 1003, and the fourth type of sub-pixels 1004, the quantity ratio of any two types of sub-pixels is 0.8 to 1.2. For example, the quantity ratio of the first type of sub-pixels 1001 and the second type of sub-pixels 1002 is 0.8 to 1.2, and the quantity ratio of the third type of sub-pixels 1003 and the fourth type of sub-pixels 1004 is 0.8 to 1.2. For example, among the first type of sub-pixels 1001, the second type of sub-pixels 1002, the third type of sub-pixels 1003, and the fourth type of sub-pixels 1004, the quantity ratio of any two types of sub-pixels is 0.9 to 1.1.

[0176] For example, as Figure 1 shown, among the first type of sub-pixels 1001, the second type of sub-pixels 1002, the third type of sub-pixels 1003, and the fourth type of sub-pixels 1004, the directions in which the vertices of the first corner portion 1011 point to the vertices of the second corner portion 1012 are the direction D2, the direction D3, the direction D4, and the direction D1, respectively. For example, in the light-emitting region of the first type of sub-pixels 1001, the direction in which the vertex of the first corner portion 1011 points to the vertex of the second corner portion 1012 is the direction D2; in the light-emitting region of the second type of sub-pixels 1002, the direction in which the vertex of the first corner portion 1011 points to the vertex of the second corner portion 1012 is the direction D3; in the light-emitting region of the third type of sub-pixels 1003, the direction in which the vertex of the first corner portion 1011 points to the vertex of the second corner portion 1012 is the direction D4; in the light-emitting region of the fourth type of sub-pixels 1004, the direction in which the vertex of the first corner portion 1011 points to the vertex of the second corner portion 1012 is the direction D1.

[0177] For example, as Figure 1 shown, among the first type of sub-pixels 1001 and the second type of sub-pixels 1002, the directions in which the vertices of the first corner portion 1011 point to the vertices of the second corner portions 1012 opposite thereto are opposite, for example, parallel to the column direction; among the third type of sub-pixels 1003 and the fourth type of sub-pixels 1004, the directions in which the vertices of the first corner portion 1011 point to the vertices of the second corner portions 1012 opposite thereto are opposite, for example, parallel to the row direction. Thus, the direction D2 and the direction D3 are opposite, and the direction D4 and the direction D1 are opposite.

[0178] Embodiments of the present disclosure schematically show that the third color sub-pixel includes four different types of sub-pixels, but is not limited thereto. At least one of the first color sub-pixel and the second color sub-pixel may also include the above four different types of sub-pixels. The direction in which the vertex of the first corner of different types of sub-pixels in other color sub-pixels points to the vertex of the second corner may be parallel to the row direction or the column direction, or may intersect the row direction or the column direction.

[0179] In the display substrate provided by the embodiments of the present disclosure, by providing four different types of sub-pixels, it is beneficial to improve the color deviation problem during the display of the display substrate. In addition, in a general display substrate, the shapes of the four corners included in the opening areas of different color sub-pixels are the same. Compared with such a display substrate, the display substrate provided by the embodiments of the present disclosure is beneficial to reduce the graininess that appears during the display of the display substrate by providing the above four different types of sub-pixels.

[0180] For example, as Figure 1 shown, a plurality of first pixel rows 01 include a first sub-pixel row 011 and a second sub-pixel row 012 alternately arranged in the column direction. The same color sub-pixels in the first sub-pixel row 011 include a first type of sub-pixel 1001 and a second type of sub-pixel 1002 alternately arranged in the row direction. The same color sub-pixels in the second sub-pixel row 012 include a third type of sub-pixel 1003 and a fourth type of sub-pixel 1004 alternately arranged in the row direction. For example, the same color sub-pixels in each first pixel row 01 include two types of sub-pixels, and the orientations of the first corners 1011 in these two types of sub-pixels are opposite, and the orientations of the first corners 1011 in adjacent first pixel rows 01 intersect.

[0181] For example, as Figure 1 shown, a plurality of first pixel columns 03 include a first sub-pixel column 031 and a second sub-pixel column 032 alternately arranged in the row direction. The same color sub-pixels in the first sub-pixel column 031 include a first type of sub-pixel 1001 and a second type of sub-pixel 1002 alternately arranged in the column direction. The same color sub-pixels in the second sub-pixel column 032 include a third type of sub-pixel 1003 and a fourth type of sub-pixel 1004 alternately arranged in the column direction. For example, the same color sub-pixels in each first pixel column 03 include two types of sub-pixels, and the orientations of the first corners 1011 in these two types of sub-pixels are opposite, and the orientations of the first corners 1011 in adjacent first pixel columns 03 intersect.

[0182] For example, as Figure 1 and Figure 5 shown, at least one of the third color sub-pixel 130 and the first color sub-pixel 110 includes a first type of sub-pixel 1001, a second type of sub-pixel 1002, a third type of sub-pixel 1003, and a fourth type of sub-pixel 1004.

[0183] For example, as Figure 5 shown, both the first color sub-pixel 110 and the third color sub-pixel 130 include a first type of sub-pixel 1001, a second type of sub-pixel 1002, a third type of sub-pixel 1003, and a fourth type of sub-pixel 1004.

[0184] For example, as Figure 5 shown, four corners of one of the third color sub-pixel 130 and the first color sub-pixel 110 include one first corner 1011, and four corners of the other color sub-pixel include at most three first corners 1011; or, four corners of one of the third color sub-pixel 130 and the first color sub-pixel 110 include two first corners 1011, and four corners of the other color sub-pixel include two or three first corners 1011; or, both the third color sub-pixel 130 and the first color sub-pixel 110 include three first corners 1011.

[0185] For example, as Figure 5 shown, four corners of the third color sub-pixel 130 include one first corner 1011, and four corners of at least a part of the first color sub-pixel 110 include at least two first corners 1011. For example, four corners of the first color sub-pixel 110 include two first corners 1011 or three first corners 1011.

[0186] When both the first color sub-pixel and the third color sub-pixel include four different types of sub-pixels, the embodiments of the present disclosure do not limit the number of first corners in the first color sub-pixel and the third color sub-pixel. The number of first corners included in the first color sub-pixel and the third color sub-pixel may be the same or different. For example, when the number of first corners included in the first color sub-pixel and the third color sub-pixel is the same, the number of first corners included in the second color sub-pixel is different from the number of first corners included in the first color sub-pixel.

[0187] For example, the embodiments of the present disclosure are not limited to each first pixel row or each first pixel column including only two types of sub-pixels. At least one first pixel row or at least one first pixel column may further include three types of sub-pixels or four types of sub-pixels, so as to be beneficial to improving the color deviation problem that occurs when the display substrate performs detailed displays such as horizontal lines or vertical lines.

[0188] For example, as Figure 1As shown, the first color sub-pixels 110 and the second color sub-pixels 120 are alternately arranged along a first diagonal direction to form a first group, and the third color sub-pixels 130 and the second color sub-pixels 120 are alternately arranged along the first diagonal direction to form a second group. The first group and the second group are alternately arranged along a second diagonal direction. The first diagonal direction and the second diagonal direction intersect with each other, and both intersect with the row direction and the column direction. For example, at least one type of color sub-pixels arranged along the first diagonal direction may include at least one type of sub-pixels, and at least one type of color sub-pixels arranged along the second diagonal direction may include at least one type of sub-pixels. For example, the same color sub-pixels arranged along at least one of the above diagonal directions may include four different types of sub-pixels, which is beneficial to improving the color deviation problem that occurs when the display substrate performs detailed displays such as diagonal lines.

[0189] For example, as Figures 1 to 8 shown, at least one of the four corners of at least some of the second color sub-pixels 120 includes at least one first corner 1011. The second color sub-pixels 120 include a fifth type of sub-pixels 1005, a sixth type of sub-pixels 1006, a seventh type of sub-pixels 1007, and an eighth type of sub-pixels 1008. Among different types of sub-pixels, the direction in which the vertex of the first corner 1011 points to the vertex of the second corner 1012 opposite thereto is different. The selection of the reference first corner among the second color sub-pixels and the definition of different types of sub-pixels are the same as the above selection method and the definition of different types of sub-pixels, and will not be elaborated here.

[0190] For example, as Figures 1 to 8 shown, among the fifth type of sub-pixels 1005, the sixth type of sub-pixels 1006, the seventh type of sub-pixels 1007, and the eighth type of sub-pixels 1008, the directions in which the vertex of the first corner 1011 points to the vertex of the second corner 1012 opposite thereto are the first direction P1, the second direction P2, the third direction P3, and the fourth direction P4 respectively. The first direction P1, the second direction P2, the third direction P3, and the fourth direction P4 all intersect with the row direction and the column direction. For example, the first direction P1 is opposite to the fourth direction P4, and the second direction P2 is opposite to the third direction P3.

[0191] For example, as Figure 1 and Figure 8As shown, a plurality of second pixel rows 02 include third sub-pixel rows 021 and fourth sub-pixel rows 022 alternately arranged in the column direction. The third sub-pixel rows 021 include fifth-type sub-pixels 1005 and sixth-type sub-pixels 1006 alternately arranged in the row direction. The fourth sub-pixel rows 022 include seventh-type sub-pixels 1007 and eighth-type sub-pixels 1008 alternately arranged in the row direction. For example, in each second pixel row 02, the sub-pixels of the same color include two types of sub-pixels, and the orientations of the first corners 1011 of these two types of sub-pixels intersect. The orientations of the two first corners 1011 located in adjacent second pixel rows 02 can be opposite or intersecting.

[0192] For example, as Figure 1 and Figure 8 shown, a plurality of second pixel columns 04 include third sub-pixel columns 041 and fourth sub-pixel columns 042 alternately arranged in the row direction. The third sub-pixel columns 041 include fifth-type sub-pixels 1005 and seventh-type sub-pixels 1007 alternately arranged in the column direction. The fourth sub-pixel columns 042 include sixth-type sub-pixels 1006 and eighth-type sub-pixels 1008 alternately arranged in the column direction. For example, in each second pixel column 04, the sub-pixels of the same color include two types of sub-pixels, and the orientations of the first corners 1011 of these two types of sub-pixels intersect. The orientations of the two first corners 1011 located in adjacent second pixel columns 04 can be opposite or intersecting.

[0193] For example, as Figure 1 shown, the display substrate includes a plurality of sub-pixel groups 1000. The plurality of sub-pixel groups 1000 are arranged in a plurality of first sub-pixel group rows 1-1 in the row direction, and adjacent first sub-pixel group rows 1-1 arranged in the column direction are staggered from each other in the row direction. For example, adjacent first sub-pixel group rows 1-1 arranged in the column direction are staggered from each other by a pitch of one sub-pixel group 1000 in the row direction.

[0194] For example, as Figure 1 shown, at least some of the sub-pixel groups 1000 are surrounded by a circle of alternately arranged first-color sub-pixels 110 and second-color sub-pixels 120. For example, a first-color sub-pixel 110 is provided between the two closest sub-pixels 100 of two adjacent sub-pixel groups 1000 arranged in the row direction, and a first-color sub-pixel 110 is provided between the two closest sub-pixels 100 of two adjacent sub-pixel groups 1000 arranged in the column direction.

[0195] For example, as Figure 1As shown, each sub-pixel group 1000 includes a first-color sub-pixel 110, four second-color sub-pixels 120 surrounding the first-color sub-pixel 110, and four third-color sub-pixels 130 surrounding the first-color sub-pixel 110. The first corner portions 1011 of at least one of the third-color sub-pixels 130 and the second-color sub-pixels 120 all face the first-color sub-pixel 110. For example, the first corner portions 1011 of both the third-color sub-pixels 130 and the second-color sub-pixels 120 face the first-color sub-pixel 110. For example, the top corners at the edge in each sub-pixel group 1000 are not the first corner portions 1011, and the arrangement of the above sub-pixel groups 1000 is a structure similar to a three-order Magic Cube.

[0196] For example, as Figure 1 shown, in at least some of the sub-pixel groups 1000, all four corner portions of the first-color sub-pixel 110 are the first corner portions 1011, and the four corner portions of the second-color sub-pixel 120 include two first corner portions 1011. The first corner portions 1011 of both the third-color sub-pixels 130 and the second-color sub-pixels 120 face the first-color sub-pixel 110.

[0197] For example, as Figure 1 and Figure 5 respectively show, the number of the first corner portions included in the second-color sub-pixel can be one or two, but is not limited thereto. It can also not include the first corner portion, or include three or four first corner portions, and the distribution of the first corner portions in the second-color sub-pixel can be set according to the actual product requirements.

[0198] For example, Figure 9 is a schematic diagram of another sub-pixel group provided according to an embodiment of the present disclosure. Figure 9 The shown sub-pixel group 1000 is different from the Figure 1 shown sub-pixel group 1000 in that, in this example, the connecting lines of the intersection points of the extension lines of the sides of the second-color sub-pixels 120 in the sub-pixel group 1000 form a rhombus. For example, at least one of the diagonals of the rhombus is parallel to the row direction and the column direction. For example, the area ratio of the light-emitting region of the second-color sub-pixel 120 to the light-emitting region of the third-color sub-pixel 130 can be 0.8 to 1.2. For example, the area ratio of the light-emitting region of the second-color sub-pixel 120 to the light-emitting region of the first-color sub-pixel can be 0.8 to 1.2.

[0199] For example, Figure 9 the distribution rule of the first corner portions of the shown second-color sub-pixels 120 can be the same as the Figures 1 - 8 distribution rule of the first corner portions in the shown second-color sub-pixels 120, which will not be elaborated here. Figure 9 The distribution rule of the first corner portions of the other color sub-pixels shown can be the same as the Figures 1 - 8The distribution rule of the first corners of the other color sub-pixels shown is the same, and will not be elaborated here.

[0200] For example, in the display substrate provided by the embodiments of the present disclosure, among the first color sub-pixels, the second color sub-pixels, and the third color sub-pixels, one of the color sub-pixels may not include the first corner, and the other two color sub-pixels include different numbers of first corners. For example, the sub-pixel that does not include the first corner may be a red sub-pixel, a green sub-pixel, or a blue sub-pixel, and the embodiments of the present disclosure do not limit this.

[0201] For example, in an example of the embodiments of the present disclosure, the sub-pixels located at the outermost edge of the display area of the display substrate may include a row or a column of alternately arranged first color sub-pixels and third color sub-pixels. The first corners in the row or column of sub-pixels located at the outermost edge may all face the outside of the display area, so as to prevent the edge from turning purple when the display substrate is displaying, and it is also beneficial to improve the serration at the edge of the display area.

[0202] For example, in an example of the embodiments of the present disclosure, the sub-pixels located at the outermost edge of the display area of the display substrate may include a row or a column of second color sub-pixels. The first corners in the row or column of second color sub-pixels located at the outermost edge may all face the outside of the display area, so as to prevent the edge from turning blue when the display substrate is displaying, and it is also beneficial to improve the serration at the edge of the display area.

[0203] The embodiments of the present disclosure are not limited to the edges connecting adjacent top corners in the light-emitting area being straight edges. For example, they can also be curved edges, such as curved edges that are concave inward or convex outward. Then, the length of the edge connecting adjacent top corners can also refer to the length of the curved edge, and the curved edge refers to the part other than the endpoints of the rounded chamfer.

[0204] For example, the embodiments of the present disclosure are not limited to the shape of the second color sub-pixel being rectangular, and it can also be an oval shape, an olive shape (such as a shape with a wide middle and narrow ends), etc.

[0205] Another embodiment of the present disclosure provides a display device, including the above-mentioned display substrate.

[0206] In the display device provided by the embodiments of the present disclosure, the different numbers of first corners set in at least two different color sub-pixels are beneficial to adjusting the brightness center in at least part of the display area to make its distribution more uniform.

[0207] For example, the display device provided by the embodiments of the present disclosure can be a light-emitting diode display device.

[0208] For example, the display device may further include a cover plate located on the display side of the display substrate.

[0209] For example, the display device can be any product or component with a display function, such as a TV, digital camera, mobile phone, watch, tablet computer, laptop, navigator, etc. This embodiment is not limited thereto.

[0210] For example, the display device can be a display device with an under-screen camera, and the display device includes functional components, such as at least one of a camera module (for example, a front camera module), a 3D structured light module (for example, a 3D structured light sensor), a time-of-flight 3D imaging module (for example, a time-of-flight sensor), an infrared sensing module (for example, an infrared sensing sensor), etc.

[0211] The following points need to be explained:

[0212] (1) In the accompanying drawings of the embodiments of the present disclosure, only the structures related to the embodiments of the present disclosure are involved, and other structures can refer to the general design.

[0213] (2) Without conflict, the features in the same embodiment and different embodiments of the present disclosure can be combined with each other.

[0214] The above is only an exemplary implementation manner of the present disclosure, and is not used to limit the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
