[0022] For example, in the display substrate provided in an embodiment of the present disclosure, the length of the third connection line is less than the length of the first connection line.

The area of the seventh sub-part is equal to the area of the eighth sub-part. The shape of the seventh curved side is the same as the shape of the second curved side, and the shape of the eighth curved side is the same as the shape of the second curved side.

[0032] For example, in the display substrate provided in an embodiment of the present disclosure, in each sub-pixel group, a first central connection line and a second central connection line between the center of the first-color sub-pixel and the centers of the two second-color sub-pixels and a third central connection line and a fourth central connection line between the center of the third-color sub-pixel and the centers of the two second-color sub-pixels form a virtual quadrilateral, and at least one interior angle of the virtual quadrilateral is not equal to 90 degrees.

[0033] For example, in the display substrate provided in an embodiment of the present disclosure, the value range of an interior angle of the virtual quadrilateral is 84 - 94 degrees.

[0034] For example, in the display substrate provided in an embodiment of the present disclosure, a center connection line of two of the first color sub-pixels and two of the third color sub-pixels in two adjacent sub-pixel groups in the second direction may form a second virtual quadrilateral, and at least one interior angle of the second virtual quadrilateral is not equal to 90 degrees.

[0067] 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 some but not all of the embodiments of the present disclosure. 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.

[0068] 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 "first", "second" and similar terms 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 term cover the elements or items listed after this term and their equivalents, without excluding other elements or items. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0069] Unless otherwise defined, features such as "parallel", "perpendicular", and "identical" used in the embodiments of the present disclosure include the strict sense of "parallel", "perpendicular", "identical", etc., as well as cases with certain errors such as "substantially parallel", "substantially perpendicular", and "substantially identical". For example, the above "substantially" may mean that the difference between the compared objects is within 10% or 5% of the average value of the compared objects. When the number of a component or element is not specifically indicated in the following text of the embodiments of the present disclosure, it means that the component or element can be one or more, or can be understood as at least one. "At least one" means one or more, and "a plurality" means at least two. The "same-layer setting" in the embodiments of the present disclosure refers to the relationship between multiple film layers formed of the same material after the same step (for example, one-step patterning process). Here, "same layer" does not always mean that the thicknesses of multiple film layers are the same or the heights of multiple film layers in the cross-sectional view are the same.

[0070] In an organic light-emitting diode display device, the light-emitting functional layer may include not only a light-emitting layer directly used for light emission, but also functional film layers such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer that assist in light emission. In the research, the inventors of the present application noticed that some currently shaped (such as rectangular) sub-pixels are prone to color separation phenomena in certain products or environments.

[0071] In response, the embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes a substrate; a plurality of sub-pixels located on the substrate; the shape of the positive projection of at least one sub-pixel on the substrate includes a first shape, the first shape includes a first curved side and a second curved side, the two ends of the first curved side and the two ends of the second curved side are respectively connected to form a first connection point and a second connection point; the length of the first connection line between the first connection point and the second connection point is the maximum length of the first shape in the extending direction of the first connection line, and the first shape is divided by the first connection line into a first sub-part including the first curved side and a second sub-part including the second curved side; the area of the first sub-part is larger than the area of the second sub-part, and the maximum vertical distance between each point on the first curved side and the first connection line is greater than the maximum vertical distance between each point on the second curved side and the first connection line. Thus, the display substrate can reduce or even avoid the occurrence of color separation phenomena by setting a shape including a curved side, and can also flexibly adjust the sizes and distances of different sub-pixels according to the light-emitting efficiency and color indicators of different color sub-pixels to achieve a better display effect.

[0072] Next, the display substrate and the display device provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0073] An embodiment of the present disclosure provides a display substrate. Figure 1A A plan view of a display substrate provided by an embodiment of the present disclosure. As Figure 1A As shown, the display substrate 100 includes a substrate 110 and a plurality of sub-pixels 200; the plurality of sub-pixels 200 are located on the substrate 110; the shape of the orthographic projection of at least one sub-pixel 200 on the substrate 110 includes a first shape 310, and the first shape 310 includes a first curved edge 311 and a second curved edge 312; both ends of the first curved edge 311 and the second curved edge 312 are connected respectively, and form a first connection point P1 and a second connection point P2, that is to say, one end of the first curved edge 311 is connected to one end of the second curved edge 312, and forms the first connection point P1, the other end of the first curved edge 311 is connected to the other end of the second curved edge 312, and forms the second connection point P2. Thus, the first curved edge 311 and the second curved edge 312 can enclose the outer contour of the first shape 310.

[0074] As Figure 1A shown, the length of the first connection line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extending direction of the first connection line CL1, and the first shape 310 is divided by the first connection line CL1 into a first sub-part 310A including the first curved edge 311 and a second sub-part 310B including the second curved edge 312; the area of the first sub-part 310A is larger than the area of the second sub-part 310B, and the maximum vertical distance between each point on the first curved edge 311 and the first connection line CL1 is greater than the maximum vertical distance between each point on the second curved edge 312 and the first connection line CL1. It should be noted that the maximum vertical distance between each point on the above-mentioned first curved edge and the first connection line refers to the largest one among the multiple vertical distances between each point on the first curved edge and the first connection line, and the maximum vertical distance between each point on the second curved edge and the first connection line refers to the largest one among the multiple vertical distances between each point on the second curved edge and the first connection line.

[0075] In the display substrate provided by the embodiments of the present disclosure, since the shape of the positive projection of at least one sub-pixel on the substrate includes a first shape, and the first shape includes a first curved side and a second curved side, the shape of the positive projection of at least one sub-pixel on the substrate is smoother, thereby reducing or even avoiding the occurrence of color separation. In addition, since the first shape is divided by a first connection line into a first sub-part including the first curved side and a second sub-part including the second curved side; the area of the first sub-part is larger than that of the second sub-part, and the maximum vertical distance from each point on the first curved side to the first connection line is greater than the maximum vertical distance from each point on the second curved side to the first connection line, the sub-pixel with the first shape can better avoid the occurrence of color separation. In addition, the display substrate can flexibly adjust the size and distance of different sub-pixels according to the luminous efficiency and color indicators of different color sub-pixels by setting the above-mentioned first curved side and second curved side, so as to achieve a better display effect. It should be noted that the above color indicators can be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the sub-pixels.

[0076] On the other hand, since the maximum vertical distance from each point on the first curved side to the first connection line is greater than the maximum vertical distance from each point on the second curved side to the first connection line, there is a larger space at the position where the second curved side is far from the first curved side. Thus, other functional components such as spacers, fingerprint recognition units, face recognition units, and photosensitive devices can also be formed at the position where the second curved side is far from the first curved side on the display substrate, so that other functions can be better integrated on the display substrate. In addition, the display substrate can also form a semi-transparent or transparent area at the position where the second curved side is far from the first curved side to allow light to penetrate the semi-transparent or transparent area, thereby realizing a transparent display area. It should be noted that a photosensitive device, such as a camera, can be provided on the back of the semi-transparent or transparent area of the display substrate.

[0077] In some examples, such as Figure 1A shown, the curvature of the vertex of the first curved side 311 far from the first connection line CL1 is greater than the curvature of the vertex of the second curved side 312 far from the first connection line CL1.

[0078] In some examples, such as Figure 1A shown, the first curved side 311 is a continuously curved side, and the second curved side 312 is a continuously curved side. Of course, the embodiments of the present disclosure include but are not limited to this. The first curved side can also be a non-continuously curved side, for example, it can include a small straight line part, and the second curved side can also be a non-continuously curved side, for example, it can include a small straight line part.

[0079] In some examples, such as Figure 1AAs shown, a plurality of sub-pixels 200 include a first color sub-pixel 210, a second color sub-pixel 220, and a third color sub-pixel 230; the first color sub-pixel 210 is configured to emit light of a first color, the second color sub-pixel 220 is configured to emit light of a second color, and the third color sub-pixel 230 is configured to emit light of a third color; the shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is a first shape 310; a plurality of third color sub-pixels 230 are arranged in an array along the row direction and the column direction to form a third color sub-pixel row 237 extending in the row direction, and a plurality of third color sub-pixel rows 237 are arranged in sequence along the column direction; the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in a direction perpendicular to the first connection line CL1, and in the same third color sub-pixel row 237, the arrangement orders of two adjacent third color sub-pixels 230 are opposite.

[0080] In the display substrate provided in this example, since the arrangement orders of two adjacent third color sub-pixels in the same third color sub-pixel row are opposite, the distribution of the third color sub-pixels with different arrangement orders in the same third color sub-pixel row is relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0081] It should be noted that Figure 1A In the display substrate shown, the shape of the orthographic projection of the third color sub-pixel on the substrate is a first shape, but the embodiments of the present disclosure include but are not limited to this. In some examples, one of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel has a first shape, and the remaining two are circular or oval. In some examples, two of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel have a first shape, and the remaining one is circular or oval. In some examples, all three of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel have a first shape.

[0082] In some examples, such as Figure 1AAs shown, in the same third-color sub-pixel row 237, the center connection line of the third-color sub-pixels 230 is a broken line; that is, the centers of the third-color sub-pixels 230 in the third-color sub-pixel row 237 are not on the same straight line. A plurality of first-color sub-pixels 210 are arranged in an array in the row direction and the column direction to form a first-color sub-pixel row 217 extending in the row direction, and a plurality of first-color sub-pixel rows 217 are arranged in sequence in the column direction. In the same first-color sub-pixel row 217, the center connection line of the first-color sub-pixels 210 is a straight line; that is, the centers of the first-color sub-pixels 210 in the first-color sub-pixel row 217 are on the same straight line. And, the above-mentioned straight line and the broken line can intersect. Of course, the embodiments of the present disclosure include but are not limited to this, and the centers of the third-color sub-pixels in the third-color sub-pixel row may also be on the same straight line.

[0083] In some examples, as Figure 1A shown, the area of the third-color sub-pixel 230 is larger than the area of the first-color sub-pixel 210, and the area of the third-color sub-pixel 230 is larger than the area of the second-color sub-pixel 210. By setting the area of the sub-pixel with a lower luminous lifetime to be larger, the service life of the sub-pixel with a lower luminous lifetime can be improved, thereby balancing the service lives of different sub-pixels.

[0084] In some examples, the area of the third-color sub-pixel 230 may also be smaller than the area of the first-color sub-pixel 210, and the area of the third-color sub-pixel 230 may also be smaller than the area of the second-color sub-pixel 210. In some display devices, since some sub-pixels have less light loss during the light output process compared to other sub-pixels, their areas can be appropriately reduced to maximize the areas of other sub-pixels with more light loss. For example, in a display device with light conversion, the area of the sub-pixel with a lower light conversion efficiency is smaller than the area of the sub-pixel with a higher light conversion efficiency. For example, in a display device with light conversion, the area of the sub-pixel that does not require light conversion is smaller than the area of the sub-pixel that requires light conversion.

[0085] In some embodiments, the shape and area of each color sub-pixel may refer to the shape and area of the part for light emission. For example, the shape and area of each sub-pixel may be the shape and area defined by the pixel opening of the pixel defining layer. The pixel defining layer is disposed on the side of one electrode of the light-emitting diode away from the substrate, and includes at least part of the electrode. A light-emitting functional layer is formed in the pixel opening of the pixel defining layer, and another electrode of the light-emitting diode is further disposed on the side of the light-emitting functional layer away from the substrate.

[0086] In some embodiments, the shapes and areas of the respective color sub-pixels may refer to the shapes and areas of the portions for emitting light. For example, the shapes and areas of the respective sub-pixels are the shapes and areas of the color filter layers corresponding to transmitting the respective colors in the color filter layer, such as the shapes and areas of the openings of the respective color filter layers defined by the black matrix. For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include but are not limited to this, and the first color, the second color, and the third color may also be other colors.

[0087] In some examples, as Figure 1A shown, the arrangement orders of the first bending edge 311 and the second bending edge 312 include a first order and a second order that are opposite to each other. In the same third color sub-pixel row 237, the difference between the number of third color sub-pixels 230 having the first order and the number of third color sub-pixels 230 having the second order is less than 10. Thus, in the same third color sub-pixel row, the distribution of the third color sub-pixels having different arrangement orders is relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0088] For example, in the same third color sub-pixel row 237, the difference between the number of third color sub-pixels 230 having the first order and the number of third color sub-pixels 230 having the second order is less than 2, so that the distribution of the third color sub-pixels having different arrangement orders is more uniform.

[0089] For example, as Figure 1A shown, in the same third color sub-pixel row 237, the first bending edge 311 and the second bending edge 312 in the first shape 310 of one of the two adjacent third color sub-pixels 230 may be arranged in the Figure 1A direction order from left to right in, and the first bending edge 311 and the second bending edge 312 in the first shape 310 of the other third color sub-pixel 230 among the two adjacent third color sub-pixels 230 may be Figure 1A in the direction order from right to left in. Again, for example, as Figure 1A shown, in the same third color sub-pixel row 237, the first bending edge 311 and the second bending edge 312 in the first shape 310 of one of the two adjacent third color sub-pixels 230 may be Figure 1A in the direction order from top to bottom in, and the first bending edge 311 and the second bending edge 312 in the first shape 310 of the other third color sub-pixel 230 among the two adjacent third color sub-pixels 230 may be Figure 1A in the direction order from bottom to top in.

[0090] In some examples, as Figure 1A As shown, for one of the two adjacent third-color sub-pixel rows 237, the extending direction of the first connection line CL1 of the first shape 310 of the third-color sub-pixels 230 in the third-color sub-pixel row 237 is parallel to the row direction, and for the other of the two adjacent third-color sub-pixel rows 237, the extending direction of the first connection line CL1 of the first shape 310 of the third-color sub-pixels 230 in the third-color sub-pixel row 237 is parallel to the column direction. Thus, by setting the extending directions of the first connection lines of the third-color sub-pixels in two adjacent third-color sub-pixel rows to be parallel to the row direction and the column direction respectively, the display substrate can further ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0091] In some examples, such as Figure 1A As shown, the shape of the first-color sub-pixels 210 can be circular, and the shape of the second-color sub-pixels 220 can be circular. Of course, the embodiments of the present disclosure include but are not limited to this. The shapes of the first-color sub-pixels and the second-color sub-pixels can also be oval or rounded rectangles.

[0092] In some examples, such as Figure 1A As shown, the area of the first-color sub-pixels 210 is larger than the area of the second-color sub-pixels 220. By setting the area of the sub-pixels with a lower luminous lifetime in the first-color sub-pixels and the second-color sub-pixels to be larger, the service life of the sub-pixels with a lower luminous lifetime can be improved, thereby balancing the service lives of different sub-pixels.

[0093] In some examples, such as Figure 1A As shown, in at least part of the display area of the display substrate, the shapes of all the third-color sub-pixels 230 are the same, the shapes of all the second-color sub-pixels 220 are the same, and the shapes of all the first-color sub-pixels 210 are the same. It should be noted that the above at least part of the display area can be an area with a similar pixel driving method or similar display requirements, such as the area on the display substrate for light-emitting display, the transparent display area, or the area where a camera, a fingerprint recognition unit, a face recognition unit, a color film unit, or other functional elements are provided. Of course, the embodiments of the present disclosure include but are not limited to this. The above at least part of the display area can also include other areas other than the above areas.

[0094] In some examples, the above at least part of the display area can be an area located near the center of the display substrate. Again, for example, the above at least part of the display area can also be an area located near the edge of the display area, such as an edge row or an edge column.

[0095] In some examples, at least part of the above-mentioned display area may include 10 rows and 10 columns of sub-pixels; that is, at least in the display area including 10 rows and 10 columns of sub-pixels, the shapes of all the third-color sub-pixels are the same, the shapes of all the second-color sub-pixels are the same, and the shapes of all the first-color sub-pixels are the same.

[0096] In some examples, in more than 50% of the display area of the display substrate, the shapes of all the third-color sub-pixels are the same, the shapes of all the second-color sub-pixels are the same, and the shapes of all the first-color sub-pixels are the same.

[0097] Figure 2 The figure is a schematic cross-sectional view of a display substrate provided by an embodiment of the present disclosure. As Figure 1A and Figure 2 shown, the display substrate 100 further includes a plurality of anodes 175, a pixel defining layer 180, and a light-emitting functional layer 190; the plurality of anodes 175 are located on the substrate 110; the pixel defining layer 180 is located on the substrate 110; the light-emitting functional layer 190 is located on the side of the plurality of anodes 175 and the pixel defining layer 180 away from the substrate 110. A plurality of pixel openings 185 are provided on the pixel defining layer 180. The light-emitting functional layer 190 includes a light-emitting layer 192. The light-emitting layer 192 includes a plurality of light-emitting portions 195. The plurality of light-emitting portions 195 are disposed in the plurality of pixel openings 185 and are driven by the plurality of anodes 175 exposed by the plurality of pixel openings 185 to form a plurality of light-emitting structures 250 of a plurality of sub-pixels 200; the shape of the orthographic projection of each sub-pixel 200 on the substrate 110 is the shape of the orthographic projection of the corresponding pixel opening 185 of the sub-pixel 200 on the substrate 110. That is to say, the display substrate can be an array substrate for display. It should be noted that the above-mentioned light-emitting portion disposed in the pixel opening means that at least part of the light-emitting portion is disposed in the pixel opening, and the size of the light-emitting portion can be larger than the size of the pixel opening; in addition, the above-mentioned light-emitting functional layer can not only include a light-emitting functional layer directly used for light emission, but also include functional film layers such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer that assist in light emission.

[0098] In some examples, the display substrate can also define the shape of each sub-pixel by providing a black matrix and black matrix openings. At this time, the shape of the above-mentioned light-emitting portion can be the same as or different from the shape of the corresponding pixel opening or black matrix opening; the center of the shape of the above-mentioned light-emitting portion and the center of the shape of the corresponding pixel opening or black matrix opening can coincide or not coincide.

[0099] In some examples, in a certain sub-pixel, the shape of the positive projection of the pixel opening on the substrate has a first shape, and the shape of the positive projection of the corresponding black matrix opening on the substrate can be circular. For another example, the shape of the positive projection of the pixel opening on the substrate is circular, and the shape of the positive projection of the corresponding black matrix opening on the substrate can be the first shape. For another example, the centers of the positive projections of the pixel opening and the black matrix opening on the substrate may coincide or may not coincide.

[0100] In some examples, as Figure 1A shown, in the sub-pixel 230 having the first shape 310, the shape of the positive projection of the light-emitting portion 195 on the substrate 110 is a rounded rectangle 350. The rounded rectangle 350 includes a first rounded portion 351 and a second rounded portion 352 that are oppositely arranged. The first rounded portion 350 is located on the side of the first curved side 311 away from the second curved side 312, and the second rounded portion 352 is located on the side of the second curved side 312 away from the first curved side 311. The distance between the first vertex 351P of the first rounded portion 351 away from the pixel opening 185 and the first curved side 311 is less than the distance between the second vertex 352P of the second rounded portion 352 away from the pixel opening 185 and the second curved side 312. Since the distance between the first vertex of the first rounded portion away from the pixel opening and the first curved side is less than the distance between the second vertex of the second rounded portion away from the pixel opening and the second curved side, other functional components such as spacers, fingerprint recognition units, and photosensitive devices can be formed at the position of the second curved side away from the first curved side in this display device, so that other functions can be better integrated on the display substrate.

[0101] In some examples, in addition to the light-emitting layer 192, the light-emitting functional layer 190 may further include other film layers that assist in light emission, such as a hole injection layer, a hole transport layer, an electron injection layer, an electron transport layer, etc.; at least one of these film layers may also be patterned, so as to have the same or similar pattern as the light-emitting layer; at least one of these film layers may not be patterned.

[0102] In some examples, as Figure 1A shown, in the sub-pixel 230 having the first shape 310, the rounded rectangle 350 further includes a third rounded portion 353 and a fourth rounded portion 354 that are oppositely arranged. The line connecting the third vertex 353P of the third rounded portion 353 away from the pixel opening 185 and the fourth vertex 354P of the fourth rounded portion 354 away from the pixel opening 185 is substantially parallel to the first line CL1.

[0103] In some examples, as Figure 1A shown, a plurality of sub-pixels 200 can be arranged in an array on the substrate 110 according to a certain pixel arrangement structure for light-emitting display.

[0104] In some examples, such as Figure 1A shown, a plurality of sub-pixels 200 includes a plurality of sub-pixel groups 260. Each sub-pixel group 260 includes one first-color sub-pixel 210, two second-color sub-pixels 220, and one third-color sub-pixel 230. In each sub-pixel group 260, the first-color sub-pixel 210 and the third-color sub-pixel 230 are arranged along the first direction X, the two second-color sub-pixels 220 are arranged along the second direction Y, and the center connection line of the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects with the center connection line of the two second-color sub-pixels 220. When the display substrate provided in this example is used for display, the two second-color sub-pixels 220 in one pixel group can respectively form two independent light-emitting pixel points with the first-color sub-pixel 210 and the third-color sub-pixel 230, so as to achieve a higher resolution through the principle of pixel borrowing. It should be noted that the above-mentioned "center connection line" refers to the connection line of the centers of the positive projections of the two sub-pixels on the substrate; and the above-mentioned "center" can be the brightness center of the sub-pixel or the geometric center of the positive projection of the sub-pixel on the substrate. In addition, the shape of the above-mentioned sub-pixel can be the range of the actual effective light-emitting area of the sub-pixel, or the range of the light-emitting area restricted by some limiting structures or blocking structures.

[0105] In some examples, such as Figure 1A shown, the first connection line CL1 can extend along the first direction X or along the second direction Y. Of course, the embodiments of the present disclosure include but are not limited to this. The extension direction of the first connection line forms a certain angle with the first direction X or the second direction Y. For example, the included angle between the extension direction of the first connection line and the first direction X or the second direction Y is in the range of 40-50 degrees.

[0106] In some examples, such as Figure 1A shown, the first shape 310 can be an axisymmetric figure. At this time, the axis of symmetry of the first shape 310 can be the above-mentioned first direction X or the second direction Y.

[0107] In some examples, such as Figure 1A shown, the shape of the positive projection of the first-color sub-pixel 210 on the substrate 110 can also be an axisymmetric figure, and the shape of the positive projection of the second-color sub-pixel 220 on the substrate 110 can be an axisymmetric figure.

[0108] In some examples, such as Figure 1AAs shown, in each sub-pixel group 260, a first center connection line 410 between the centers of the first color sub-pixels 210 and the centers of the two second color sub-pixels 220, a second center connection line 420, a third center connection line 430 between the centers of the third color sub-pixels 230 and the centers of the two second color sub-pixels 220, and a fourth center connection line 440 form a first virtual quadrilateral 480, and at least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Thus, the display substrate can better avoid the occurrence of color separation phenomenon, and can also flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indices of different color sub-pixels to achieve a better display effect.

[0109] In some examples, as Figure 1A shown, the value range of an interior angle of the above-mentioned first virtual quadrilateral 480 is 84 - 94 degrees. For example, an interior angle of the above-mentioned virtual quadrilateral can be 87 degrees, 92 degrees, or 93 degrees.

[0110] In some examples, the above-mentioned first virtual quadrilateral can be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of the present disclosure include but are not limited to this, and the interior angle of the above-mentioned first virtual quadrilateral can also be equal to 90 degrees, that is, the above-mentioned first virtual quadrilateral is a rectangle.

[0111] In some examples, as Figure 1A shown, a center connection line between two first color sub-pixels 210 and two third color sub-pixels 230 in two adjacent sub-pixel groups 260 in the second direction can form a second virtual quadrilateral 490, and at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Thus, the display substrate can better avoid the occurrence of color separation phenomenon, and can also flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indices of different color sub-pixels to achieve a better display effect.

[0112] In some examples, the above-mentioned second virtual quadrilateral can be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of the present disclosure include but are not limited to this, and the interior angle of the above-mentioned second virtual quadrilateral can also be equal to 90 degrees, that is, the above-mentioned second virtual quadrilateral is a rectangle.

[0113] In some examples, as Figure 1AAs shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 respectively have a first distance D1 and a second distance D2, and the third color sub-pixel 230 and the two second color sub-pixels 220 respectively have a third distance D3 and a fourth distance D4; at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal in magnitude. Thus, the display substrate can ensure uniform distribution of each sub-pixel, thereby improving the pixel density on the premise of making full use of the process precision. For example, the distance between two sub-pixels is the closest distance between the boundaries of the two sub-pixels. For example, the distance between two sub-pixels is the distance between the intersection points of the line connecting the centers of the two sub-pixels and the boundaries of the two sub-pixels.

[0114] In some examples, as Figure 1A shown, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal to further ensure uniform distribution of each sub-pixel, thereby further improving the pixel density on the premise of making full use of the process precision. Of course, the embodiments of the present disclosure include but are not limited to this. For example, the first distance D1 and the second distance D2 are equal, and the third distance D3 and the fourth distance D4 are not equal; or for another example, the first distance D1, the second distance D2, and the third distance are equal, and the third distance D3 and the fourth distance D4 are not equal.

[0115] In some examples, the range of the ratio of any two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 can be 0.7 - 1.5.

[0116] In some examples, the ratio range of the aperture ratio of the second color sub-pixel 220 to the aperture ratio of the first color sub-pixel 210 is 1 - 1 / 3; the ratio range of the aperture ratio of the second color sub-pixel 220 to the aperture ratio of the third color sub-pixel 230 is 1 - 1 / 3; the ratio range of the aperture ratio of the first color sub-pixel 210 to the aperture ratio of the third color sub-pixel 230 is 1 - 1 / 3. Of course, the embodiments of the present disclosure include but are not limited to this.

[0118] In some examples, as Figure 1BAs shown, the first bending edge 311 may include a first inflection point G1, and the bending directions of the first bending edge 311 on both sides of the first inflection point G1 are opposite; for example, the first bending edge 311 may include two first inflection points G1, thereby forming two outwardly convex curved line segments and one inwardly concave curved line segment.

[0119] In some examples, as Figure 1C shown, the second bending edge 312 may include a second inflection point G2, and the bending directions of the second bending edge 312 on both sides of the second inflection point G1 are opposite; for example, the second bending edge 312 may include two second inflection points G2, thereby forming two outwardly convex curved line segments and one inwardly concave curved line segment.

[0120] In some examples, as Figure 1D shown, the first bending edge 311 may include a first inflection point G1, and the bending directions of the first bending edge 311 on both sides of the first inflection point G1 are opposite; for example, the first bending edge 311 may include two first inflection points G1, thereby forming two outwardly convex curved line segments and one inwardly concave curved line segment. At the same time, the second bending edge 312 may include a second inflection point G2, and the bending directions of the second bending edge 312 on both sides of the second inflection point G1 are opposite; for example, the second bending edge 312 may include two second inflection points G2, thereby forming two outwardly convex curved line segments and one inwardly concave curved line segment.

[0121] Figure 3 This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As Figure 3 shown, the display substrate 100 further includes a color filter layer 510, and the color filter layer 510 includes a plurality of color filters 512; the shapes of the plurality of color filters 512 define the light-emitting regions of the plurality of sub-pixels 200, and the shape of the orthographic projection of each sub-pixel 200 on the substrate 110 is the shape of the orthographic projection of the corresponding color filter 512 of the sub-pixel 200 on the substrate 110.

[0122] In some examples, the display substrate is a color filter substrate.

[0123] In some examples, the display substrate is a display substrate that includes both light-emitting elements and color filters. The shape of the orthographic projection of each sub-pixel on the substrate is the shape of the overlapping portion of the pixel defining layer opening corresponding to the light-emitting element and the corresponding color filter in the direction perpendicular to the substrate. For example, the shape of the overlapping portion of the pixel defining layer opening corresponding to the light-emitting element and the corresponding color filter in the direction perpendicular to the substrate is the shape of the color defining layer opening, and the projection of the pixel defining layer opening on the substrate falls within the projection of the corresponding color filter on the substrate. For example, the shape of the overlapping portion of the pixel defining layer opening corresponding to the light-emitting element and the corresponding color filter in the direction perpendicular to the substrate is the shape of the color filter, and the projection of the color filter on the substrate falls within the projection of the corresponding pixel defining layer opening on the substrate.

[0124] In some examples, as Figure 3 shown, the shape of the orthographic projection of the color filter 512 corresponding to the first color sub-pixel 210 on the substrate 110 is circular; the shape of the orthographic projection of the color filter 512 corresponding to the second color sub-pixel 220 on the substrate 110 is circular; the shape of the orthographic projection of the color filter 512 corresponding to the third color sub-pixel 230 on the substrate 110 is the first shape 310.

[0125] In some examples, as Figure 3 shown, the first bending edge and the second bending edge of the color filter 512 corresponding to the third color sub-pixel 230 have an arrangement order in the direction perpendicular to the first connection line CL1. In the same row of third color sub-pixels, the arrangement orders of two adjacent third color sub-pixels are opposite, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles. It should be noted that the arrangement order of the above first bending edge and second bending edge can be referred to the Figure 1A related description and will not be elaborated here.

[0126] In some examples, as Figure 3 shown, the extension direction of the first connection line CL1 of the first shape of the color filter 512 corresponding to the third color sub-pixel 230 in one of the two adjacent rows 237 of third color sub-pixels 237 is parallel to the row direction, and the extension direction of the first connection line CL1 of the first shape of the color filter 512 corresponding to the third color sub-pixel 230 in the other of the two adjacent rows 237 of third color sub-pixels 237 is parallel to the column direction, which can further ensure that the display effects presented by the display substrate at different viewing angles are the same, and further improve the display uniformity at different viewing angles.

[0127] In some examples, as Figure 3As shown, one of the two first connecting lines of the first shape of the filter 512 corresponding to the two third color sub-pixels 230 adjacent to a second color sub-pixel 220 is parallel to the row direction, and the other is parallel to the column direction.

[0128] In some examples, as Figure 3 shown, the length of the first connecting line of the first shape of the filter 512 corresponding to the third color sub-pixel 230 is greater than the diameter of the filter 512 corresponding to the first color sub-pixel 210 and the diameter of the filter 512 corresponding to the second color sub-pixel 220. Of course, the embodiments of the present disclosure include but are not limited to this. The length of the first connecting line of the first shape of the filter corresponding to the third color sub-pixel may be less than the diameter of the filter corresponding to the first color sub-pixel and greater than the diameter of the filter corresponding to the second color sub-pixel.

[0129] In some examples, as Figure 3 shown, the centers of the multiple third color sub-pixels 230 arranged in the first direction X are located on a straight line extending along the first direction X; the centers of the multiple third color sub-pixels 230 arranged in the second direction Y are located on a straight line extending along the second direction Y. Of course, the embodiments of the present disclosure include but are not limited to this.

[0130] Figure 4 This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As Figure 4 shown, the display substrate 100 includes a substrate 110 and multiple sub-pixels 200; the multiple sub-pixels 200 are located on the substrate 110; the shape of the orthographic projection of at least one sub-pixel 200 on the substrate 110 includes a first shape 310, and the first shape 310 includes a first curved edge 311 and a second curved edge 312; the two ends of the first curved edge 311 and the second curved edge 312 are respectively connected to form a first connection point P1 and a second connection point P2. The length of the first connecting line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extending direction of the first connecting line CL1. The first shape 310 is divided by the first connecting line CL1 into a first sub-part 310A including the first curved edge 311 and a second sub-part 310B including the second curved edge 312; the area of the first sub-part 310A is greater than the area of the second sub-part 310B, and the maximum vertical distance between each point on the first curved edge 311 and the first connecting line CL1 is greater than the maximum vertical distance between each point on the second curved edge 312 and the first connecting line CL1.

[0131] As Figure 4As shown, in the first shape 310, the first curved edge 311 is a continuously curved edge, and the second curved edge 312 includes a first sub-curved edge 312A, a second sub-curved edge 312B, and a first straight edge 312C. The first straight edge 312C is connected to the first sub-curved edge 312A and the second sub-curved edge 312B respectively. Thus, the display substrate can also avoid the occurrence of color separation phenomenon to a certain extent. In addition, the display substrate can flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indexes of different color sub-pixels by setting the above-mentioned first curved edge and the second curved edge including the first straight edge, so as to achieve a better display effect. Moreover, the display substrate can also form other functional components such as spacers, fingerprint recognition units, and photosensitive devices at positions where the first straight edge is far from the first curved edge, so that other functions can be better integrated on the display substrate.

[0132] In some examples, as Figure 4 shown, a plurality of sub-pixels 200 include a first color sub-pixel 210, a second color sub-pixel 220, and a third color sub-pixel 230; the first color sub-pixel 210 is configured to emit light of a first color, the second color sub-pixel 220 is configured to emit light of a second color, and the third color sub-pixel 230 is configured to emit light of a third color; the shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is the first shape 310; a plurality of third color sub-pixels 230 are arranged in an array along the row direction and the column direction to form a third color sub-pixel row 237 extending along the row direction, and a plurality of third color sub-pixel rows 237 are arranged in sequence along the column direction; the first curved edge 311 and the second curved edge 312 of the first shape 310 have an arrangement order in a direction perpendicular to the first connection line CL1. In the same third color sub-pixel row 237, the arrangement orders of two adjacent third color sub-pixels 230 are opposite. Therefore, in the same third color sub-pixel row, the distributions of the third color sub-pixels with different arrangement orders are relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0133] In some examples, as Figure 4 shown, the area of the third color sub-pixel 230 is larger than the area of the first color sub-pixel 210, and the area of the third color sub-pixel 230 is larger than the area of the second color sub-pixel 210. By setting the area of the sub-pixel with a lower luminous lifetime to be larger, the service life of the sub-pixel with a lower luminous lifetime can be improved, thereby balancing the service lives of different sub-pixels.

[0134] For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include but are not limited to this. The first color, the second color, and the third color may also be other colors.

[0135] In some examples, such as Figure 4 shown, the arrangement order of the first bending edge 311 and the second bending edge 312 includes a first order and a second order that are opposite to each other. In the same third-color sub-pixel row 237, the difference between the number of third-color sub-pixels 230 with the first order and the number of third-color sub-pixels 230 with the second order is less than 10. Thus, in the same third-color sub-pixel row, the distribution of third-color sub-pixels with different arrangement orders is relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0136] For example, in the same third-color sub-pixel row 237, the difference between the number of third-color sub-pixels 230 with the first order and the number of third-color sub-pixels 230 with the second order is less than 2, so that the distribution of third-color sub-pixels with different arrangement orders is more uniform.

[0137] For example, as Figure 4 shown, in the same third-color sub-pixel row 237, for one of the two adjacent third-color sub-pixels 230, the first bending edge 311 and the second bending edge 312 in the first shape 310 of the third-color sub-pixel 230 can be arranged in the order of the direction from left to right in Figure 4 ; for the other of the two adjacent third-color sub-pixels 230, the first bending edge 311 and the second bending edge 312 in the first shape 310 of the third-color sub-pixel 230 can be Figure 4 in the order of the direction from right to left in. Also for example, as Figure 4 shown, in the same third-color sub-pixel row 237, for one of the two adjacent third-color sub-pixels 230, the first bending edge 311 and the second bending edge 312 in the first shape 310 of the third-color sub-pixel 230 can be Figure 4 in the order of the direction from top to bottom in; for the other of the two adjacent third-color sub-pixels 230, the first bending edge 311 and the second bending edge 312 in the first shape 310 of the third-color sub-pixel 230 can be Figure 4 in the order of the direction from bottom to top in.

[0138] In some examples, such as Figure 4As shown, the extension direction of the first connection line CL1 of the first shape 310 of the third color sub-pixels 230 in one of the two adjacent third color sub-pixel rows 237 is parallel to the row direction, and the extension direction of the first connection line CL1 of the first shape 310 of the third color sub-pixels 230 in the other of the two adjacent third color sub-pixel rows 237 is parallel to the column direction. Thus, by setting the extension directions of the first connection lines of the third color sub-pixels in the two adjacent third color sub-pixel rows to be parallel to the row direction and the column direction respectively, the display substrate can further ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0139] In some examples, as Figure 4 shown, the first straight edge 312C can be parallel to the first connection line CL1. Of course, the embodiments of the present disclosure include but are not limited to this, and the first straight edge can also be non-parallel to the first connection line.

[0140] In some examples, as Figure 4 shown, the first shape 310 can be the larger circular part formed after being cut by the first straight line 312C. At this time, the curvatures of the points on the first curved edge 311 are the same, the curvatures of the points on the first sub-curved edge 312A are the same, and the curvatures of the points on the second sub-curved edge 312B are the same. Of course, the embodiments of the present disclosure include but are not limited to this.

[0141] In some examples, as Figure 4 shown, the curvatures of the points on the first curved edge 311, the curvatures of the points on the first sub-curved edge 312A, and the curvatures of the points on the second sub-curved edge 312B are the same.

[0142] In some examples, the curvatures of at least half of the edges on the first curved edge are the same. In some examples, the curvatures of at least half of the edges on the first sub-curved edge are the same. In some examples, the curvatures of at least half of the edges on the second sub-curved edge are the same. In some examples, the curvatures of at least half of the edges on the second curved edge are the same.

[0143] In some examples, as Figure 4 shown, the shape of the first color sub-pixel 210 can be circular, and the shape of the second color sub-pixel 220 can be oval. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the first color sub-pixel and the second color sub-pixel can also be other shapes.

[0144] In some examples, as Figure 4As shown, the included angle between the extending direction of the major axis of the ellipse of the second color sub-pixel 220 and the first direction X or the second direction Y is less than 90 degrees, for example, 30 - 60 degrees. Of course, the embodiments of the present disclosure include but are not limited to this. The major axis of the ellipse of the second color sub-pixel may also extend along the first direction or the second direction.

[0145] In some examples, as Figure 4 shown, the size of the ellipse of the second color sub-pixel 220 in the direction of its major axis is approximately equal to the diameter of the circle of the first color sub-pixel 210.

[0146] In some examples, as Figure 4 shown, the display substrate 100 may be an array substrate for display. The lamination relationship of the anode, pixel defining layer, and light-emitting functional layer in the array substrate in the direction perpendicular to the substrate can be referred to Figure 2 for the relevant description. Of course, the embodiments of the present disclosure include but are not limited to this. The display substrate may also be a color filter substrate, and can be referred to Figure 3 for the relevant description.

[0147] In some examples, as Figure 4 shown, in the sub-pixel 230 having the first shape 310, the shape of the orthographic projection of the light-emitting portion 195 on the substrate 110 is a rounded rectangle 350. The rounded rectangle 350 includes a first rounded portion 351 and a second rounded portion 352 that are oppositely arranged. The first rounded portion 350 is located on the side of the first curved edge 311 away from the second curved edge 312, and the second rounded portion 352 is located on the side of the second curved edge 312 away from the first curved edge 311; the distance between the first vertex 351P of the first rounded portion 351 away from the pixel opening 185 and the first curved edge 311 is less than the distance between the second vertex 352P of the second rounded portion 352 away from the pixel opening 185 and the first straight edge 312C. Thus, the space at the position of the first straight edge away from the first curved edge is larger, and other functional components such as spacers, fingerprint recognition units, and photosensitive devices can be formed at the position of the first straight edge away from the first curved edge of the display substrate, so that other functions can be better integrated on the display substrate.

[0148] In some examples, as Figure 4 shown, in the sub-pixel 230 having the first shape 310, the rounded rectangle 350 further includes a third rounded portion 353 and a fourth rounded portion 354 that are oppositely arranged. The connection line between the third vertex 353P of the third rounded portion 353 away from the pixel opening 185 and the fourth vertex 354P of the fourth rounded portion 354 away from the pixel opening 185 is substantially parallel to the first connection line CL1.

[0149] In some examples, as Figure 4As shown, a plurality of sub-pixels 200 include a plurality of sub-pixel groups 260. Each sub-pixel group 260 includes one first-color sub-pixel 210, two second-color sub-pixels 220, and one third-color sub-pixel 230. In each sub-pixel group 260, the first-color sub-pixel 210 and the third-color sub-pixel 230 are arranged along the first direction X, the two second-color sub-pixels 220 are arranged along the second direction, and the central connection line between the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects the central connection line between the two second-color sub-pixels 220. When the display substrate provided in this example is used for display, the two second-color sub-pixels 220 in one pixel group can respectively form two independent light-emitting pixel points with the first-color sub-pixel 210 and the third-color sub-pixel 230, so as to achieve a higher resolution through the principle of pixel borrowing.

[0150] In some examples, as Figure 4 shown, a plurality of first-color sub-pixels 210 and a plurality of third-color sub-pixels 230 can be alternately arranged along the first direction X to form a first sub-pixel row 270. A plurality of second-color sub-pixels 220 can be arranged along the first direction X to form a second sub-pixel row 280. A plurality of first sub-pixel rows 270 and a plurality of second sub-pixel rows 280 are alternately arranged along the second direction.

[0151] In some examples, as Figure 4 shown, in the first sub-pixel row 270, the central connection line of the first-color sub-pixels 210 is a straight line, the central connection line of the third-color sub-pixels 230 is a broken line, and the straight line intersects the broken line. Of course, the embodiments of the present disclosure include but are not limited to this, and the central connection line of the third-color sub-pixel can also be a straight line.

[0152] In some examples, as Figure 4 shown, in the second sub-pixel row 280, the central connection line of the second-color sub-pixels 220 is a straight line. Of course, the embodiments of the present disclosure include but are not limited to this, and the central connection line of the third-color sub-pixel can also be a broken line. In some examples, as Figure 4 shown, the first straight edge 312C can be substantially parallel to the second direction. Of course, the embodiments of the present disclosure include but are not limited to this, and the first straight edge can also not be parallel to the second direction.

[0153] In some examples, as Figure 4 shown, in the same second sub-pixel row 280, the major axes of the ellipses of two adjacent second-color sub-pixels 220 are axisymmetric, for example, axisymmetric about the second direction. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of the ellipses of two adjacent second-color sub-pixels 220 is 80-100 degrees.

[0154] In some examples, as Figure 4As shown, in two adjacent second sub-pixel rows 280, the major axes of the ellipses of two adjacent second color sub-pixels 220 in the second direction are axisymmetric or mirror-symmetric, for example, axisymmetric about the first direction X. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of two adjacent second color sub-pixels 220 in the second direction Y is 80 - 100 degrees.

[0155] In some examples, as Figure 4 shown, in each sub-pixel group 260, the first central connection line between the center of the first color sub-pixel 210 and the centers of two second color sub-pixels 220, the second central connection line, the third central connection line between the center of the third color sub-pixel 230 and the centers of two second color sub-pixels 220, and the fourth central connection line form a first virtual quadrilateral, and at least one interior angle of the first virtual quadrilateral is not equal to 90 degrees. Thus, the display substrate can flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indicators of different color sub-pixels to achieve a better display effect.. It should be noted that, for clarity, Figure 4 the reference numerals of each central connection line are not shown, and the reference numerals of the above-mentioned first central connection line, second central connection line, third central connection line, and fourth central connection line can be referred to Figure 1A .

[0156] In some examples, as Figure 4 shown, the value range of an interior angle of the above-mentioned first virtual quadrilateral 480 is 84 - 94 degrees. For example, an interior angle of the above-mentioned virtual quadrilateral can be 92 degrees.

[0157] In some examples, as Figure 4 shown, the central connection lines of two first color sub-pixels 210 and two third color sub-pixels 230 in two adjacent sub-pixel groups 260 in the second direction Y can form a second virtual quadrilateral, and at least one interior angle of the second virtual quadrilateral is not equal to 90 degrees. Thus, the display substrate can flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indicators of different color sub-pixels to achieve a better display effect.. It should be noted that, for clarity, Figure 4 the reference numeral of the second virtual quadrilateral is not shown, and the reference numeral of the above-mentioned second virtual quadrilateral can be referred to Figure 1A .

[0158] In some examples, as Figure 4As shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 respectively have a first distance D1 and a second distance D2, and the third color sub-pixel 230 and the two second color sub-pixels 220 respectively have a third distance D3 and a fourth distance D4; at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal in magnitude. Thus, the display substrate can ensure uniform distribution of each sub-pixel, thereby improving the pixel density on the premise of making full use of the process accuracy.

[0159] In some examples, as Figure 4 shown, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal, so as to further ensure uniform distribution of each sub-pixel, thereby further improving the pixel density on the premise of making full use of the process accuracy.

[0160] In some examples, as Figure 4 shown, the fifth distance D5 between the first straight edge 312C of the third color sub-pixel 230 and the adjacent first color sub-pixel 210 can be greater than the above-mentioned first distance D1, second distance D2, third distance D3, and fourth distance D4 respectively.

[0161] Figure 5A This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As Figure 5A shown, the display substrate 100 includes a substrate 110 and a plurality of sub-pixels 200; the plurality of sub-pixels 200 are located on the substrate 110; the shape of the positive projection of at least one sub-pixel 200 on the substrate 110 includes a first shape 310, and the first shape 310 includes a first curved edge 311 and a second curved edge 312; the two ends of the first curved edge 311 and the second curved edge 312 are respectively connected to form a first connection point P1 and a second connection point P2. The length of the first connection line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extending direction of the first connection line CL1, and the first shape 310 is divided by the first connection line CL1 into a first sub-part 310A including the first curved edge 311 and a second sub-part 310B including the second curved edge 312; the area of the first sub-part 310A is larger than the area of the second sub-part 310B, and the maximum vertical distance between each point on the first curved edge 311 and the first connection line CL1 is greater than the maximum vertical distance between each point on the second curved edge 312 and the first connection line CL1.

[0162] As Figure 5A shown, the first shape 310 and Figure 1AThe first shapes 310 shown have the same shape, that is, the first curved side 311 of the first shape 310 is a continuously curved side, and the second curved side 312 of the first shape 310 is also a continuously curved side. Thus, the display substrate can also avoid the occurrence of color separation phenomenon to a certain extent, and can also flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiency and color indexes of different color sub-pixels by setting the above-mentioned first curved side and second curved side, so as to achieve a better display effect. Moreover, the display substrate can also form other functional components such as spacers, fingerprint recognition units, photosensitive devices, etc. at positions where the second curved side is far from the first curved side, so that other functions can be better integrated on the display substrate.

[0163] In some examples, such as Figure 5A shown, a plurality of sub-pixels 200 include a first color sub-pixel 210, a second color sub-pixel 220, and a third color sub-pixel 230; the first color sub-pixel 210 is configured to emit light of a first color, the second color sub-pixel 220 is configured to emit light of a second color, and the third color sub-pixel 230 is configured to emit light of a third color; the shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is the first shape 310; a plurality of third color sub-pixels 230 are arranged in an array in the row direction and the column direction to form a third color sub-pixel row 237 extending in the row direction, and a plurality of third color sub-pixel rows 237 are arranged in sequence in the column direction; the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in a direction perpendicular to the first connection line CL1, and in the same third color sub-pixel row 237, the arrangement orders of two adjacent third color sub-pixels 230 are opposite. Therefore, in the same third color sub-pixel row, the distributions of third color sub-pixels with different arrangement orders are relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0164] In some examples, such as Figure 5A shown, the shape of the first color sub-pixel 210 may be circular, and the shape of the second color sub-pixel 220 may be oval. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the first color sub-pixel and the second color sub-pixel may also be other shapes.

[0165] In some examples, such as Figure 5A shown, the size of the oval of the second color sub-pixel 220 in its major axis direction is approximately equal to the diameter of the circle of the first color sub-pixel 210.

[0166] In some examples, such as Figure 5AAs shown, in the same second sub-pixel row 280, the major axes of the ellipses of two adjacent second color sub-pixels 220 are axisymmetric or mirror-symmetric, for example, axisymmetric or mirror-symmetric about the second direction Y. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of the ellipses of two adjacent second color sub-pixels 220 is 80 - 100 degrees.

[0167] In some examples, as Figure 5A shown, in two adjacent second sub-pixel rows 280, the major axes of the ellipses of two second color sub-pixels 220 adjacent in the second direction Y are axisymmetric or mirror-symmetric, for example, axisymmetric or mirror-symmetric about the first direction X. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of the ellipses of two second color sub-pixels 220 adjacent in the second direction Y is 80 - 100 degrees.

[0168] In some examples, as Figure 5A shown, the display substrate 100 can be an array substrate for display, and the stacking relationship of the anode, pixel defining layer, and light-emitting functional layer in this array substrate in the direction perpendicular to the substrate can be referred to Figure 2 for the relevant description. Of course, the embodiments of the present disclosure include but are not limited to this. The display substrate can also be a color filter substrate, and the relevant description can be referred to Figure 3 for the relevant description.

[0169] Figure 5B is a schematic cross-sectional view of another display substrate provided by an embodiment of the present disclosure; Figure 5C is a schematic cross-sectional view of another display substrate provided by an embodiment of the present disclosure.

[0170] In some examples, as Figure 5BAs shown, the display substrate 100 further includes a plurality of anodes 175, a pixel defining layer 180, a light-emitting functional layer 190, a color filter layer 510, and a black matrix 550; the plurality of anodes 175 are located on the substrate 110; the pixel defining layer 180 is located on the substrate 110; the light-emitting functional layer 190 is located on a side of the plurality of anodes 175 and the pixel defining layer 180 away from the substrate 110. A plurality of pixel openings 185 are provided on the pixel defining layer 180. The light-emitting functional layer 190 includes a light-emitting layer 192, and the light-emitting layer 192 includes a plurality of light-emitting portions 195. The plurality of light-emitting portions 195 are disposed in the plurality of pixel openings 185 and are driven by the anodes 175 exposed by the pixel openings 185 to emit light, so as to form a plurality of light-emitting structures 250 of the plurality of sub-pixels 200. The color filter layer 510 includes a plurality of color filters 512, the black matrix 550 is disposed between adjacent color filters 512, and the color filters 512 are disposed in black matrix openings 555 of the black matrix 550. In this case, the shape of each sub-pixel can also be defined by providing a black matrix on the display substrate.

[0171] In some examples, as Figure 5B shown, the shape of the orthographic projection of the pixel opening 185 on the substrate 110 may be the same as or different from the shape of the orthographic projection of the black matrix opening 555 on the substrate 110; the center of the shape of the orthographic projection of the pixel opening 185 on the substrate 110 may coincide with or not coincide with the center of the shape of the orthographic projection of the black matrix opening 555 on the substrate 110.

[0172] In some examples, the color filter and the black matrix are at least partially overlapped. In some examples, the black matrix can also be formed by the overlap of color filters of different colors.

[0173] In some examples, as Figure 5B shown, the display substrate 100 further includes a packaging layer 520 and a cover plate 530. The packaging layer 520 is located on a side of the light-emitting functional layer 190 away from the substrate 110, and the cover plate 530 is located on a side of the color filter layer 510 away from the substrate 110. At this time, the color filter layer 510 is also formed on the packaging layer 520. Of course, the embodiments of the present disclosure include but are not limited to this. The color filter layer can also be first formed on the cover plate and then bonded to the packaging layer.

[0174] In some examples, as Figure 5CAs shown, the display substrate 100 includes a plurality of anodes 175, a pixel defining layer 180, a light-emitting functional layer 190, a color conversion layer 365, a color filter layer 510, and a black matrix 550; the plurality of anodes 175 are located on the substrate 110; the pixel defining layer 180 is located on the substrate 110; the light-emitting functional layer 190 is located on the side of the plurality of anodes 175 and the pixel defining layer 180 away from the substrate 110. A plurality of pixel openings 185 are provided on the pixel defining layer 180. The light-emitting functional layer 190 includes a light-emitting layer 192, and the light-emitting layer 192 includes a plurality of light-emitting portions 195. The plurality of light-emitting portions 195 are disposed in the plurality of pixel openings 185 and are driven by the plurality of anodes 175 exposed by the plurality of pixel openings 185 to emit light, so as to form a plurality of light-emitting structures 250 of a plurality of sub-pixels 200. The color conversion layer 565 is disposed on the side of the light-emitting portion 195 away from the substrate 110; the color filter layer 510 includes a plurality of color filters 512, and the color filters 512 are disposed on the side of the color conversion layer 565 away from the light-emitting portion 195. Thus, the color conversion layer 565 can convert the light emitted by the light-emitting structure 250 into light of a specific color, and then filter it through the corresponding color filter 512, so as to emit light of different colors with high color purity.

[0175] In some examples, the color conversion layer 565 may adopt a quantum dot layer; of course, the embodiments of the present disclosure include but are not limited to this. The color conversion layer may also adopt other types of color conversion layers.

[0176] In some examples, as Figure 5C shown, the black matrix 550 is disposed between adjacent color filters 512, and the color filters 512 are disposed in the black matrix openings 555 of the black matrix 550. In this case, the display substrate can also define the shape of each sub-pixel by setting the black matrix.

[0177] In some examples, as Figure 5C shown, the display substrate 100 further includes a packaging layer 520, an optical adhesive layer 570, and a cover plate 530. The packaging layer 520 is located on the side of the light-emitting functional layer 190 away from the substrate 110, and the color conversion layer 565 is disposed on the side of the packaging layer 520 away from the light-emitting functional layer 190 away from the substrate 110; the optical adhesive layer 570 is disposed on the side of the color conversion layer 565 away from the substrate 110, and the color filter layer 510 is located on the side of the optical adhesive layer 570 away from the color conversion layer 565; the cover plate 530 is located on the side of the color filter layer 510 away from the substrate 110. In some examples, as Figure 5C shown, the size of the orthographic projection of the color conversion layer 565 on the substrate 110 is larger than the size of the orthographic projection of the pixel opening 185 on the substrate 110; the size of the orthographic projection of the black matrix opening 555 on the substrate 110 is larger than the size of the orthographic projection of the pixel opening 185 on the substrate 110.

[0178] In some examples, such as Figure 5C shown, the size of the orthographic projection of the color conversion layer 565 on the substrate 110 is larger than the size of the orthographic projection of the black matrix opening 555 on the substrate 110.

[0179] In some examples, such as Figure 5A shown, in each sub-pixel group 260, a first center connection line 410 between the centers of the first color sub-pixels 210 and the centers of the two second color sub-pixels 220, a second center connection line 420, a third center connection line 430 between the centers of the third color sub-pixels 230 and the centers of the two second color sub-pixels 220, and a fourth center connection line 440 form a first virtual quadrilateral 480, and at least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Thus, the display substrate can flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indices of different color sub-pixels to achieve a better display effect.. It should be noted that, for clarity, Figure 5A the reference numerals of the respective center connection lines are not shown, and the reference numerals of the above-mentioned first center connection line, second center connection line, third center connection line, and fourth center connection line can be referred to Figure 1A .

[0180] In some examples, such as Figure 5A shown, the value range of an interior angle of the above-mentioned first virtual quadrilateral 480 is 84 - 94 degrees. For example, an interior angle of the above-mentioned virtual quadrilateral can be 92 degrees.

[0181] In some examples, such as Figure 5A shown, the center connection lines of two first color sub-pixels 210 and two third color sub-pixels 230 in two adjacent sub-pixel groups 260 in the second direction Y can form a second virtual quadrilateral 490, and at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Thus, the display substrate can better avoid the occurrence of color separation phenomenon, and can also flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indices of different color sub-pixels to achieve a better display effect. It should be noted that, for clarity, Figure 5A the reference numeral of the second virtual quadrilateral is not shown, and the reference numeral of the above-mentioned second virtual quadrilateral can be referred to Figure 1A .

[0182] In some examples, such as Figure 5AAs shown, in each sub-pixel group 260, the first color sub-pixels 210 and the two second color sub-pixels 220 have a first distance D1 and a second distance D2 respectively, and the third color sub-pixels 230 and the two second color sub-pixels 220 have a third distance D3 and a fourth distance D4 respectively; at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal in magnitude. Thus, the display substrate can ensure that the sub-pixels are evenly distributed, thereby improving the pixel density on the premise of making full use of the process accuracy.

[0183] In some examples, as Figure 5A shown, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal, so as to further ensure that the sub-pixels are evenly distributed, thereby further improving the pixel density on the premise of making full use of the process accuracy.

[0184] Figure 6A-6B This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As Fig. 6A shown, the display substrate 100 includes a substrate 110 and a plurality of sub-pixels 200; the plurality of sub-pixels 200 are located on the substrate 110; the shape of the orthographic projection of at least one sub-pixel 200 on the substrate 110 includes a first shape 310, and the specific description of the first shape 310 can be referred to Figure 1A for the relevant description, which will not be elaborated here.

[0185] As Fig. 6A shown, the shape of the orthographic projection of at least one sub-pixel 200 on the substrate 110 includes a second shape 320, the second shape 320 includes a third curved side 321 and a fourth curved side 322, the two ends of the third curved side 321 and the two ends of the fourth curved side 322 are connected respectively, and a third connection point P3 and a fourth connection point P4 are formed; the length of the second connection line CL2 of the third connection point P3 and the fourth connection point P4 is the maximum length of the second shape 320 in the extending direction of the second connection line CL2, and the second shape 320 is divided by the second connection line CL2 into a third sub-part 320A including the third curved side 321 and a fourth sub-part 320B including the fourth curved side 322; the area of the third sub-part 320A is larger than the area of the fourth sub-part 320B, and the maximum vertical distance from each point on the third curved side 321 to the second connection line CL2 is greater than the maximum vertical distance from each point on the fourth curved side 322 to the second connection line CL2. It should be noted that the maximum vertical distance from each point on the above-mentioned third curved side to the second connection line refers to the largest one among the multiple vertical distances from each point on the third curved side to the second connection line, and the maximum vertical distance from each point on the fourth curved side to the second connection line refers to the largest one among the multiple vertical distances from each point on the fourth curved side to the second connection line.

[0186] In the display substrate provided by the embodiments of the present disclosure, on the basis that the shape of the orthographic projection of at least one sub-pixel on the substrate includes a first shape, the shape of the orthographic projection of at least one sub-pixel on the substrate includes a second shape, and the second shape includes a third curved edge and a fourth curved edge. Therefore, the shape of the orthographic projection of at least one sub-pixel on the substrate is smoother, thereby reducing or even avoiding the occurrence of color separation phenomenon. In addition, since the second shape is divided by a second connection line into a third sub-part including the third curved edge and a fourth sub-part including the fourth curved edge; the area of the third sub-part is larger than the area of the fourth sub-part, and the maximum vertical distance from each point on the third curved edge to the second connection line is greater than the maximum vertical distance from each point on the fourth curved edge to the second connection line. Therefore, the sub-pixel with the second shape can better avoid the occurrence of color separation phenomenon. In addition, the display substrate can flexibly adjust the size and distance of different sub-pixels according to the luminous efficiency and color index of different color sub-pixels by setting the above-mentioned third curved edge and fourth curved edge to achieve a better display effect. And, the display substrate can also form other functional components such as spacers, fingerprint recognition units, and photosensitive devices at positions where the fourth curved edge is far from the third curved edge, so that other functions can be better integrated on the display substrate. In some examples, as Fig. 6A shown, the curvature of the vertex of the third curved edge 321 far from the second connection line CL2 is greater than the curvature of the vertex of the fourth curved edge 322 far from the second connection line CL2.

[0187] In some examples, as Fig. 6A shown, the third curved edge 321 is a continuously curved edge, and the fourth curved edge 322 is a continuously curved edge.

[0188] In some examples, as Fig. 6A shown, the length of the second connection line CL2 is less than the length of the first connection line CL1. That is to say, the second shape is similar to the first shape, but the size of the second shape is smaller than the size of the first shape.

[0189] In some examples, as Fig. 6A shown, a plurality of sub-pixels 200 include a first color sub-pixel 210, a second color sub-pixel 220, and a third color sub-pixel 230; the first color sub-pixel 210 is configured to emit light of a first color, the second color sub-pixel 220 is configured to emit light of a second color, and the third color sub-pixel 230 is configured to emit light of a third color.

[0190] In some examples, as Fig. 6AAs shown, the area of the third color sub-pixel 230 is larger than that of the first color sub-pixel 210, and the area of the third color sub-pixel 230 is larger than that of the second color sub-pixel 210. By setting the area of the sub-pixel with a lower luminous lifetime to be larger, the service life of the sub-pixel with a lower luminous lifetime can be improved, thereby balancing the service lives of different sub-pixels.

[0191] For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include, but are not limited to, this. The first color, the second color, and the third color may also be other colors.

[0192] In some examples, as Fig. 6A shown, the shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is the first shape 310; a plurality of third color sub-pixels 230 are arranged in an array in the row direction and the column direction to form a third color sub-pixel row 237 extending in the row direction, and a plurality of third color sub-pixel rows 237 are arranged in sequence in the column direction; the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in a direction perpendicular to the first connection line CL1. In the same third color sub-pixel row 237, the arrangement orders of two adjacent third color sub-pixels 230 are opposite; in one of two adjacent third color sub-pixel rows 237, the extension direction of the first connection line CL1 of the first shape 310 of the third color sub-pixel 230 is parallel to the row direction, and in the other of two adjacent third color sub-pixel rows 237, the extension direction of the first connection line CL1 of the first shape 310 of the third color sub-pixel 230 is parallel to the column direction. Thus, the display substrate can make the distribution of the third color sub-pixels with different arrangement orders more uniform, thereby ensuring that the display effects presented by the display substrate at different viewing angles are the same, so as to improve the display uniformity at different viewing angles. It should be noted that the arrangement order of the first curved side and the second curved side of the above-mentioned third color sub-pixel can refer to the relevant description in Figure 1A and will not be elaborated here.

[0193] In some examples, as Fig. 6A shown, a plurality of first color sub-pixels 210 are arranged in an array in the row direction and the column direction to form a first color sub-pixel row 217 extending in the row direction, and a plurality of first color sub-pixel rows 217 are arranged in sequence in the column direction; the third curved side 321 and the fourth curved side 322 of the second shape 320 have an arrangement order in a direction perpendicular to the second connection line CL2. In the same first color sub-pixel row 217, the arrangement orders of two adjacent first color sub-pixels 210 are opposite. For example, the first color sub-pixel row 217 and the third color sub-pixel row 237 may be the same sub-pixel row.

[0194] In the display substrate provided in this example, since the arrangement orders of two adjacent first color sub-pixels in the same first color sub-pixel row are opposite to each other, the distribution of the first color sub-pixels with different arrangement orders in the same first color sub-pixel row is relatively uniform. Therefore, it can be ensured that the display effects presented by the display substrate at different viewing angles are the same, so as to improve the display uniformity at different viewing angles.

[0195] In some examples, such as Fig. 6A shown, the arrangement orders of the third bending edge 321 and the fourth bending edge 322 include a third order and a fourth order that are opposite to each other. In the same first color sub-pixel row 217, the difference between the number of the first color sub-pixels 210 with the third order and the number of the first color sub-pixels 210 with the fourth order is less than 10. Thus, in the same first color sub-pixel row, the distribution of the first color sub-pixels with different arrangement orders is relatively uniform. Therefore, it can be ensured that the display effects presented by the display substrate at different viewing angles are the same, so as to improve the display uniformity at different viewing angles.

[0196] For example, in the same first color sub-pixel row 217, the difference between the number of the first color sub-pixels 210 with the third order and the number of the first color sub-pixels 210 with the fourth order is less than 2, so that the first color sub-pixels with different arrangement orders are more uniform.

[0197] For example, as Fig. 6A shown, in the same first color sub-pixel row 217, the third bending edge 321 and the fourth bending edge 322 in the second shape 320 of one of the two adjacent first color sub-pixels 210 can be arranged in the Fig. 6A direction order from left to right in, and the third bending edge 321 and the fourth bending edge 322 in the second shape 320 of the other of the two adjacent first color sub-pixels 210 can be Fig. 6A in the direction order from right to left in. Also for example, as Fig. 6A shown, in the same first color sub-pixel row 217, the third bending edge 321 and the fourth bending edge 322 in the second shape 320 of one of the two adjacent first color sub-pixels 210 can be Fig. 6A in the direction order from top to bottom in, and the third bending edge 321 and the fourth bending edge 322 in the second shape 320 of the other of the two adjacent first color sub-pixels 210 can be Fig. 6A in the direction order from bottom to top in.

[0198] In some examples, such as Fig. 6AAs shown, among two adjacent first-color sub-pixel rows 217, the extending direction of the second connection line CL2 of the second shape 320 of the first-color sub-pixels 210 in one of the first-color sub-pixel rows 217 is parallel to the row direction, and the extending direction of the second connection line CL2 of the second shape 320 of the first-color sub-pixels 210 in the other of the two adjacent first-color sub-pixel rows 217 is parallel to the column direction. Thus, by setting the extending directions of the first connection lines of the third-color sub-pixels in two adjacent third-color sub-pixel rows to be parallel to the row direction and the column direction respectively, the display substrate can further ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0199] In some examples, as Figure 6B shown, the shape of the orthographic projection of at least one sub-pixel 200 on the substrate 110 includes a third shape 330. The third shape 330 includes a fifth curved side 331 and a sixth curved side 332. The two ends of the fifth curved side 331 and the two ends of the sixth curved side 332 are respectively connected to form a fifth connection point P5 and a sixth connection point P6. The length of the third connection line CL3 between the fifth connection point P5 and the sixth connection point P6 is the maximum length of the third shape 330 in the extending direction of the third connection line CL3. The third shape 330 is divided by the third connection line CL3 into a fifth sub-part 330A including the fifth curved side 331 and a sixth sub-part 330B including the sixth curved side 332. The area of the fifth sub-part 330A is equal to the area of the sixth sub-part 330B, and the fifth curved side 331 and the sixth curved side 332 are axially symmetrically arranged with respect to the third connection line CL3. Thus, the shape of the orthographic projection of the sub-pixel having the third shape on the substrate is smoother, thereby reducing or even avoiding the occurrence of color separation phenomenon. It should be noted that Figure 6B the display substrate shown is the same as Fig. 6A the display substrate shown. To better show the relevant features of the third-color sub-pixels, Figure 6B other reference numerals are omitted.

[0200] In some examples, as Figure 6B shown, the shape of the second-color sub-pixels 220 can be oval. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the second-color sub-pixels can also be circular.

[0201] In some examples, as Figure 6B shown, the fifth curved side 331 is a continuously curved side, and the sixth curved side 332 is a continuously curved side.

[0202] In some examples, as Figure 6B shown, the length of the third connection line CL3 is less than the length of the first connection line CL1.

[0203] In some examples, such as Fig. 6A and 6B shown, when multiple sub-pixels 200 include a first color sub-pixel 210, a second color sub-pixel 220, and a third color sub-pixel 230, the shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is a first shape 310, the shape of the orthographic projection of the first color sub-pixel 210 on the substrate 110 is a second shape 320, and the shape of the orthographic projection of the second color sub-pixel 220 on the substrate 110 is a third shape 330. Thus, the shapes of the orthographic projections of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel on the substrate are smoother, thereby reducing or even avoiding the occurrence of color separation.

[0204] In some examples, such as Fig. 6A and 6B shown, the length of the third connection line CL3 is equal to the length of the second connection line CL2, that is, the length of the major axis of the ellipse of the second color sub-pixel 220 is equal to the length of the second connection line CL2.

[0205] In some examples, such as Fig. 6A and 6B shown, multiple sub-pixels 200 include multiple sub-pixel groups 260, each sub-pixel group 260 includes one first color sub-pixel 210, two second color sub-pixels 220, and one third color sub-pixel 230; in each sub-pixel group 260, the first color sub-pixel 210 and the third color sub-pixel 230 are arranged along the first direction X, the two second color sub-pixels 220 are arranged along the second direction Y, and the center connection line of the first color sub-pixel 210 and the third color sub-pixel 230 intersects with the center connection line of the two second color sub-pixels 220. When the display substrate provided in this example is used for display, the two second color sub-pixels 220 in a pixel group can respectively form two independent light-emitting pixel points with the first color sub-pixel 210 and the third color sub-pixel 230, thereby achieving a higher resolution through the principle of pixel borrowing.

[0206] In some examples, such as Fig. 6A and 6B shown, multiple first color sub-pixels 210 and multiple third color sub-pixels 230 can be alternately arranged along the first direction X and form a first sub-pixel row 270; multiple second color sub-pixels 220 can be arranged along the first direction X and form a second sub-pixel row 280; multiple first sub-pixel rows 270 and multiple second sub-pixel rows 280 are alternately arranged along the second direction Y.

[0207] In some examples, such as Fig. 6A and 6BAs shown, in the same second sub-pixel row 280, the major axes of the ellipses of two adjacent second color sub-pixels 220 are axisymmetric, for example, axisymmetric about the second direction Y. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of the ellipses of two adjacent second color sub-pixels 220 is 80 - 100 degrees.

[0208] In some examples, as Fig. 6A and 6B shown, in two adjacent second sub-pixel rows 280, the major axes of the ellipses of two second color sub-pixels 220 adjacent in the second direction Y are axisymmetric, for example, axisymmetric about the first direction X. For example, in the same second sub-pixel row 280, the included angle range between the extension lines of the major axes of the ellipses of two second color sub-pixels 220 adjacent in the second direction Y is 80 - 100 degrees.

[0209] In some examples, as Fig. 6A and 6B shown, the display substrate 100 can be an array substrate for display, and the stacking relationship of the anode, pixel defining layer, and light-emitting functional layer in the array substrate in the direction perpendicular to the substrate can be referred to Figure 2 for the relevant description. Of course, the embodiments of the present disclosure include but are not limited to this. The display substrate can also be a color filter substrate, and the relevant description can be referred to Figure 3 for the relevant description.

[0210] In some examples, as Fig. 6A and 6B shown, in each sub-pixel group 260, the first central connection line between the center of the first color sub-pixel 210 and the centers of two second color sub-pixels 220 and the second central connection line and the third central connection line between the center of the third color sub-pixel 230 and the centers of two second color sub-pixels 220 and the fourth central connection line form a first virtual quadrilateral, and at least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Thus, the display substrate can better avoid the occurrence of color separation phenomenon, and can also flexibly adjust the sizes and distances of different sub-pixels according to the light-emitting efficiency and color indicators of different color sub-pixels to achieve a better display effect.

[0211] It should be noted that, for clarity, Fig. 6A and Figure 6B the reference numerals of each central connection line are not shown. The reference numerals of the above-mentioned first central connection line, second central connection line, third central connection line, and fourth central connection line can be referred to Figure 1A .

[0212] In some examples, as Fig. 6A and 6BAs shown, the value range of an interior angle of the above-mentioned first virtual quadrilateral 480 is 84 - 94 degrees. For example, an interior angle of the above-mentioned virtual quadrilateral can be 92 degrees.

[0213] In some examples, such as Fig. 6A and 6B As shown, the center connection lines of two first color sub-pixels 210 and two third color sub-pixels 230 in two adjacent sub-pixel groups 260 in the second direction Y can form a second virtual quadrilateral 490, and at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Thus, the display substrate can better avoid the occurrence of color separation phenomenon, and can also flexibly adjust the sizes and distances of different sub-pixels according to the luminous efficiencies and color indicators of different color sub-pixels to achieve a better display effect. It should be noted that, for clarity, Fig. 6A and Figure 6B the reference numerals of the second virtual quadrilateral are not shown, and the reference numerals of the above-mentioned second virtual quadrilateral can be referred to Figure 1A .

[0214] In some examples, such as Fig. 6A and Figure 6B As shown, in each sub-pixel group 260, the first color sub-pixel 210 and two second color sub-pixels 220 respectively have a first distance D1 and a second distance D2, and the third color sub-pixel 230 and two second color sub-pixels 220 respectively have a third distance D3 and a fourth distance D4; at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal in size. Thus, the display substrate can ensure the uniform distribution of each sub-pixel, thereby improving the pixel density on the premise of making full use of the process precision.

[0215] In some examples, such as Fig. 6A and Figure 6B As shown, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal to further ensure the uniform distribution of each sub-pixel, thereby further improving the pixel density on the premise of making full use of the process precision.

[0216] Figure 6C This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As Figure 6C shown, similar to the first shape, the fourth curved side 322 of the second shape 320 also includes a third sub-curved side 322A, a fourth sub-curved side 322B, and a second straight side 322C, and the second straight side 322C is respectively connected to the third sub-curved side 322A and the fourth sub-curved side 322C. It should be noted that, Figure 6C the arrangement of the third curved side 321 and the fourth curved side 322 of the second shape 320 of the first color sub-pixel 210 in Fig. 6ARelated description.

[0217] Fig.6D Another schematic plan view of a display substrate provided by an embodiment of the present disclosure. As Fig.6D shown, the shape of the positive projection of the third color sub-pixel 230 on the substrate 110 may be the first shape 310; the shape of the positive projection of the first color sub-pixel 210 on the substrate 110 may be the above-mentioned second shape 320; the shape of the positive projection of the second color sub-pixel 220 on the substrate 110 may be circular. It should be noted that the above-mentioned first shape and second shape may have the same shape and size as the first shape and second shape in any example of Figures 6A-6C and the arrangement thereof may also be referred to the relevant description in any example of Figures 6A-6C Related description.

[0218] Figure 7 Another schematic plan view of a display substrate provided by an embodiment of the present disclosure. As Figure 7 shown, the display substrate 100 includes a substrate 110 and a plurality of sub-pixels 200; the plurality of sub-pixels 200 are located on the substrate 110; the shape of the positive projection of at least one sub-pixel 200 on the substrate 110 includes a first shape 310, and the specific description of the first shape 310 can be referred to the relevant description of Figure 1A which will not be elaborated here.

[0219] As Figure 7 shown, the plurality of sub-pixels 200 are arranged in an array on the substrate 110 to form a display array 290. The plurality of sub-pixels 200 include boundary sub-pixels 295 located at the edge of the display array 290. The shape of the positive projection of at least one of the boundary sub-pixels 295 on the substrate 110 includes a fourth shape 340. The fourth shape 340 includes a seventh curved side 341 and an eighth curved side 342. The two ends of the seventh curved side 342 and the two ends of the eighth curved side 342 are respectively connected to form a seventh connection point P7 and an eighth connection point P8; the length of the fourth connection line CL4 between the seventh connection point P7 and the eighth connection point P8 is the maximum length of the fourth shape 340 in the extending direction of the fourth connection line CL4. The fourth shape 340 is divided by the fourth connection line CL4 into a seventh sub-part 340A including the seventh curved side 341 and an eighth sub-part 340B including the eighth curved side 342; the area of the seventh sub-part 340A is equal to the area of the eighth sub-part 340B, the shape of the seventh curved side 341 is the same as the shape of the second curved side 312, and the shape of the eighth curved side 342 is the same as the shape of the second curved side 312. That is to say, relative to the first shape, both of the two curved sides of the fourth shape are retracted inward.

[0220] In the display substrate provided in this example, on the basis that the shape of the orthographic projection of at least one sub-pixel on the substrate includes a first shape, since the shape of the orthographic projection of the boundary sub-pixel on the substrate includes a fourth shape, and the fourth shape includes a seventh curved side and an eighth curved side, the shape of the orthographic projection of the boundary sub-pixel on the substrate is smoother, thereby reducing or even avoiding the occurrence of color separation phenomenon.

[0221] In some examples, as Figure 7 shown, the seventh curved side 341 is a continuously curved side, and the eighth curved side 342 is a continuously curved side.

[0222] In some examples, as Figure 7 shown, the length of the fourth connection line CL4 is equal to the length of the first connection line CL1. Thus, both the boundary sub-pixel 295 and the third color sub-pixel 230 are configured to emit light of the third color.

[0223] In some examples, as Figure 7 shown, the display substrate 100 can be an array substrate for display. The stacking relationship of the anode, pixel defining layer, and light-emitting functional layer in the array substrate in the direction perpendicular to the substrate can be referred to Figure 2 for the relevant description. Of course, the embodiments of the present disclosure include but are not limited to this. The display substrate can also be a color filter substrate, and the relevant description can be referred to Figure 3 for the relevant description.

[0224] Figure 8 This is a schematic plan view of another display substrate provided by an embodiment of the present disclosure.

The length of the first connection line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extending direction of the first connection line CL1, and the first shape 310 is divided by the first connection line CL1 into a first sub-part 310A including the first curved side 311 and a second sub-part 310B including the second curved side 312; the area of the first sub-part 310A is greater than the area of the second sub-part 310B, and the maximum vertical distance between each point on the first curved side 311 and the first connection line CL1 is greater than the maximum vertical distance between each point on the second curved side 312 and the first connection line CL1.

[0278] As Fig. 20As shown, a plurality of sub-pixels 200 include a plurality of sub-pixel groups 260. Each sub-pixel group 260 includes one first-color sub-pixel 210, two second-color sub-pixels 220, and one third-color sub-pixel 230. In each sub-pixel group 260, the first-color sub-pixel 210 and the third-color sub-pixel 230 are arranged along the first direction X, the two second-color sub-pixels 220 are arranged along the second direction Y, and the center connection line of the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects with the center connection line of the two second-color sub-pixels 220. Of course, as Fig. 20 shown, the plurality of sub-pixels 200 are also arranged in an array along the above-mentioned first direction X and second direction Y. At this time, the value range of the angle between the first connection line CL1 of the first connection point P1 and the second connection point P2 and the first direction X is 30 - 60 degrees, for example, 45 degrees. Thus, this display substrate has a better display effect. In addition, this display substrate can also avoid the occurrence of color separation phenomenon to a certain extent. In addition, this display substrate can flexibly adjust the size and distance of different sub-pixels according to the light-emitting efficiency and color index of different color sub-pixels by setting the above-mentioned first bending edge and the second bending edge including the first straight edge, so as to achieve a better display effect. And, this display substrate can also form other functional components such as spacers, fingerprint recognition units, and photosensitive devices at the position where the first straight edge is far from the first bending edge, so that other functions can be better integrated on the display substrate.

[0279] In some examples, as Fig. 20 shown, the plurality of sub-pixels 200 include a first-color sub-pixel 210, a second-color sub-pixel 220, and a third-color sub-pixel 230. The first-color sub-pixel 210 is configured to emit light of a first color, the second-color sub-pixel 220 is configured to emit light of a second color, and the third-color sub-pixel 230 is configured to emit light of a third color.

The first bending edge 311 and the second bending edge 312 of the first shape 310 have an arrangement order in the direction perpendicular to the first connection line CL1. In the same third-color sub-pixel row 237, the arrangement orders of two adjacent third-color sub-pixels 230 are opposite. Therefore, in the same third-color sub-pixel row, the distribution of the third-color sub-pixels with different arrangement orders is relatively uniform, so as to ensure that the display effects presented by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0280] In some examples, as Fig. 20As shown, the area of the third color sub-pixel 230 is larger than that of the first color sub-pixel 210, and the area of the third color sub-pixel 230 is larger than that of the second color sub-pixel 210. By setting the area of the sub-pixel with a lower emission lifetime to be larger, the service life of the sub-pixel with a lower emission lifetime can be improved, thereby balancing the service lives of different sub-pixels.

[0281] For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include but are not limited to this, and the first color, the second color, and the third color may also be other colors.

[0282] In some examples, as Fig. 20 shown, the shape of the first color sub-pixel 210 may be circular, and the shape of the second color sub-pixel 220 may also be circular. Of course, the embodiments of the present disclosure include but are not limited to this, and the shapes of the first color sub-pixel and the second color sub-pixel may also be other shapes.

[0283] In some examples, as Fig. 20 shown, the display substrate 100 may be an array substrate for display. The lamination relationship of the anode, the pixel defining layer, and the light-emitting functional layer in the array substrate in the direction perpendicular to the substrate can be referred to Figure 2 for the relevant description. Of course, the embodiments of the present disclosure include but are not limited to this, and the display substrate may also be a color filter substrate, and reference can be made to Figure 3 for the relevant description.

As Fig.21 shown, the display device 800 includes the display substrate 100 provided in any of the above examples. Thus, the display device can also reduce or even avoid the occurrence of color separation, and can also flexibly adjust the sizes and distances of different sub-pixels according to the light-emitting efficiencies and color indicators of different color sub-pixels to achieve a better display effect. Moreover, the display substrate can also form other functional components such as spacers, fingerprint recognition units, and photosensitive devices at positions where the second bending edge is far from the first bending edge, so that other functions can be better integrated on the display substrate.

[0285] In some examples, the above display device may be an electronic product with a display function such as a television, a monitor, a navigator, a tablet computer, a laptop computer, a smart phone, etc.
