[0068] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0069] Unless otherwise defined, technical and scientific terms used in the present disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood as the usual meaning understood by one of ordinary skill in the art. The terms "first", "second", and the like used in the present disclosure do not represent any order, number, or importance, but are only used to distinguish different components. The terms "include" or "contain" and the like mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connected" or "connected" and the like are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0070] Unless otherwise defined, the features "parallel", "perpendicular", and "same" and the like used in the embodiments of the present disclosure include the cases of "strictly parallel", "strictly perpendicular", "strictly same" and the like, and the cases of "approximately parallel", "approximately perpendicular", "approximately same" and the like with certain errors. For example, the above-mentioned "approximately" can mean that the difference between the compared objects is within 10% or 5% of the average value of the compared objects. In the embodiments of the present disclosure, when the number of a component or element is not specifically indicated below, 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 "multiple" means at least two. In the embodiments of the present disclosure, "same layer" refers to the relationship between multiple film layers formed by the same material after the same step (for example, one patterning process). Here, "same layer" does not always mean that the thickness of multiple film layers is the same or the height of multiple film layers in a cross-sectional view is the same.

[0071] In an organic light-emitting diode display device, the light-emitting functional layer can not only include a light-emitting layer directly used for light emission, but also include a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer and other functional film layers assisting light emission. In research, the inventors of the present application have noticed that some sub-pixels of the current shape (for example, rectangular) are prone to cause color separation in some products or environments.

[0072] In response, this disclosure provides 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 orthographic projection of at least one sub-pixel onto the substrate includes a first shape, the first shape including a first curved edge and a second curved edge, the two ends of the first curved edge and the two ends of the second curved edge being connected respectively to form a first connection point and a second connection point; the length of a first line connecting the first connection point and the second connection point is the maximum length of the first shape in the extension direction of the first line; the first shape is divided by the first line into a first sub-part including the first curved edge and a second sub-part including the second curved edge; 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 edge and the first line is greater than the maximum vertical distance between each point on the second curved edge and the first line. Therefore, by setting a shape including curved edges, the display substrate can mitigate or even avoid color separation, and can flexibly adjust the size and distance of different sub-pixels according to the luminous efficiency and color index of different color sub-pixels to achieve a better display effect.

[0073] The display substrate and display device provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0074] One embodiment of this disclosure provides a display substrate. FIG. 1A This is a planar schematic diagram of a display substrate provided according to an embodiment of the present disclosure. FIG. 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, the first shape 310 including 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, that is, one end of the first curved edge 311 is connected to one end of the second curved edge 312 to form the first connection point P1, and the other end of the first curved edge 311 is connected to the other end of the second curved edge 312 to form the second connection point P2. Thus, the first curved edge 311 and the second curved edge 312 can form the outer contour of the first shape 310.

[0075] like FIG. 1AAs shown, the length of the first line CL1 connecting the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extension direction of the first line CL1. The first shape 310 is divided by the first line CL1 into a first sub-part 310A including a first curved edge 311 and a second sub-part 310B including a second curved edge 312. The area of ​​the first sub-part 310A is larger than the area of ​​the second sub-part 310B. The maximum perpendicular distance between each point on the first curved edge 311 and the first line CL1 is greater than the maximum perpendicular distance between each point on the second curved edge 312 and the first line CL1. It should be noted that the maximum perpendicular distance between each point on the first curved edge and the first line refers to the largest of multiple perpendicular distances between each point on the first curved edge and the first line, while the maximum perpendicular distance between each point on the second curved edge and the first line refers to the largest of multiple perpendicular distances between each point on the second curved edge and the first line.

[0076] In the display substrate provided in this embodiment, since the orthographic projection shape of at least one sub-pixel on the substrate includes a first shape, and the first shape includes a first curved edge and a second curved edge, the orthographic projection shape of at least one sub-pixel on the substrate is smoother, thereby mitigating or even avoiding color separation. Furthermore, since the first shape is divided by a first line into a first sub-part including a first curved edge and a second sub-part including a second curved edge; 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 edge and the first line is greater than the maximum vertical distance between each point on the second curved edge and the first line, the sub-pixel with the first shape can better avoid color separation. Additionally, by setting the aforementioned first and second curved edges, the display substrate can flexibly adjust the size and distance of different sub-pixels according to the luminous efficiency and color parameters of different color sub-pixels to achieve a better display effect. It should be noted that the aforementioned color parameters can be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the sub-pixel.

[0077] On the other hand, since the maximum perpendicular distance between each point on the first curved edge and the first connecting line is greater than the maximum perpendicular distance between each point on the second curved edge and the first connecting line, the space away from the first curved edge on the second curved edge is larger. Therefore, the display substrate can also form spacers, fingerprint recognition units, face recognition units, photosensitive devices, and other functional components on the location away from the first curved edge on the second curved edge, thereby better integrating other functions onto the display substrate. Additionally, the display substrate can also form a semi-transparent or transparent area on the location away from the first curved edge on the second curved edge to allow light to pass through, thus achieving a transparent display area. It should be noted that a photosensitive device, such as a camera, can be disposed on the back of the semi-transparent or transparent area of ​​the display substrate.

[0078] In some examples, such as FIG. 1A As shown, the curvature of the first curved edge 311 away from the vertex of the first connecting line CL1 is greater than the curvature of the second curved edge 312 away from the vertex of the first connecting line CL1.

[0079] In some examples, such as FIG. 1A As shown, the first curved edge 311 is a continuously curved edge, and the second curved edge 312 is a continuously curved edge. Of course, the embodiments of this disclosure include, but are not limited to, the first curved edge may also be a discontinuous curved edge, for example, it may include a short straight section, and the second curved edge may also be a discontinuous curved edge, for example, it may include a short straight section.

[0080] In some examples, such as FIG. 1A As 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 shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is a first shape 310; the plurality of third color sub-pixels 230 are arranged in an array along the row direction and the column direction to form a row of third color sub-pixels 237 extending along the row direction, and the plurality of rows of third color sub-pixels 237 are arranged sequentially 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 the direction perpendicular to the first connecting line CL1, and in the same row of third color sub-pixels 237, the arrangement order of two adjacent third color sub-pixels 230 is opposite.

[0081] In the display substrate provided in this example, since the arrangement order of two adjacent third color sub-pixels in the same third color sub-pixel row is opposite, the distribution of third color sub-pixels with different arrangement orders in the same third color sub-pixel row is relatively uniform, thereby ensuring that the display effect presented by the display substrate is the same under different viewing angles, so as to improve the display uniformity under different viewing angles.

[0082] It should be noted that, FIG. 1A The shape of the orthographic projection of the third color sub-pixel on the substrate in the illustrated display substrate is a first shape. However, embodiments of this disclosure include, but are not limited to, this. In some examples, one of the first, second, and third color sub-pixels has the first shape, while the other two are circular or elliptical. In some examples, two of the first, second, and third color sub-pixels have the first shape, while the remaining one is circular or elliptical. In some examples, all three of the first, second, and third color sub-pixels have the first shape.

[0083] In some examples, such as FIG. 1A As shown, in the same third color sub-pixel row 237, the center line connecting 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. Multiple first color sub-pixels 210 are arrayed along the row and column directions to form a first color sub-pixel row 217 extending along the row direction, and the multiple first color sub-pixel rows 217 are arranged sequentially along the column direction. In the same first color sub-pixel row 217, the center line connecting the centers 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. Furthermore, the aforementioned straight line and broken line can intersect. Of course, embodiments of this disclosure include, but are not limited to, the centers of the third color sub-pixels in the third color sub-pixel row can also be on the same straight line.

[0084] In some examples, such as FIG. 1A As 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 lifespan of the sub-pixel with a lower luminous lifetime can be increased, thereby balancing the lifespan of different sub-pixels.

[0085] In some examples, the area of ​​the third color sub-pixel 230 may 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 experience less light loss during light emission compared to other sub-pixels, their area can be appropriately reduced to maximize the area of ​​other sub-pixels with greater light loss. For example, in a display device with light conversion, the area of ​​a sub-pixel with lower light conversion efficiency is smaller than the area of ​​a sub-pixel with higher light conversion efficiency. Similarly, in a display device with light conversion, the area of ​​a sub-pixel that does not require light conversion is smaller than the area of ​​a sub-pixel that does require light conversion.

[0086] In some embodiments, the shape and area of ​​each color subpixel may refer to the shape and area of ​​the portion used for emitting light. For example, the shape and area of ​​each subpixel may be the shape and area defined by the pixel opening of the pixel defining layer, which is disposed on the side of one electrode of the light-emitting diode away from the substrate and includes at least a portion of the electrode. A light-emitting functional layer is formed in the opening of the pixel defining layer, and another electrode of the light-emitting diode is disposed on the side of the light-emitting functional layer away from the substrate.

[0087] In some embodiments, the shape and area of ​​each color subpixel may refer to the shape and area of ​​the portion used for light emission. For example, the shape and area of ​​each subpixel may be the shape and area of ​​the color filter layer corresponding to the color that transmits each color, such as the shape and area of ​​the openings of each color filter layer 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, embodiments of this disclosure include, but are not limited to, other colors such as the first color, the second color, and the third color.

[0088] In some examples, such as FIG. 1A As shown, the arrangement order of the first curved edge 311 and the second curved 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. Therefore, the distribution of third color sub-pixels with different arrangement orders in the same third color sub-pixel row is relatively uniform, thereby ensuring that the display effect presented by the display substrate is the same under different viewing angles, thus improving the display uniformity under different viewing angles.

[0089] For example, in the same row 237 of third color subpixels, the difference between the number of third color subpixels 230 with the first order and the number of third color subpixels 230 with the second order is less than 2, thereby making the distribution of third color subpixels with different arrangement orders more uniform.

[0090] For example, such as FIG. 1A As shown, in the same third color sub-pixel row 237, the first curved edge 311 and the second curved edge 312 of the first shape 310 of one of two adjacent third color sub-pixels 230 can be along... FIG. 1A Arranged sequentially from left to right, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of two adjacent third color sub-pixels 230 can be... FIG. 1A Arranged sequentially from right to left. For example, such as... FIG. 1A As shown, in the same third color sub-pixel row 237, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of two adjacent third color sub-pixels 230 can be... FIG. 1A Arranged sequentially from top to bottom, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of the two adjacent third color sub-pixels 230 can be... FIG. 1A Arranged in order from bottom to top.

[0091] In some examples, such asFIG. 1A As shown, in one of the adjacent rows of third-color sub-pixels 237, the extension direction of the first line CL1 connecting the first shape 310 of the third-color sub-pixels 230 is parallel to the row direction, while the extension direction of the first line CL1 connecting the first shape 310 of the third-color sub-pixels 230 in the other row of third-color sub-pixels 237 is parallel to the column direction. Therefore, by setting the extension direction of the first line connecting the third-color sub-pixels in two adjacent rows of third-color sub-pixels to be parallel to both the row and column directions, the display substrate can further ensure that the display effect presented by the display substrate is the same under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0092] In some examples, such as FIG. 1A As 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 circular. Of course, embodiments of this disclosure include, but are not limited to, the shapes of the first color sub-pixel and the second color sub-pixel can also be elliptical or rounded rectangles.

[0093] In some examples, such as FIG. 2 As shown, the area of ​​the first color sub-pixel 210 is larger than the area of ​​the second color sub-pixel 220. By setting the area of ​​the sub-pixel with the lower luminous lifetime in the first and second color sub-pixels to be larger, the lifespan of the sub-pixel with the lower luminous lifetime can be increased, thereby balancing the lifespan of different sub-pixels.

[0094] In some examples, such as FIG. 3 As shown, in at least a portion of the display area of ​​the display substrate, each third color sub-pixel 230 has the same shape, each second color sub-pixel 220 has the same shape, and each first color sub-pixel 210 has the same shape. It should be noted that the aforementioned at least a portion of the display area can be an area with a similar pixel driving method or similar display requirements, such as an area on the display substrate that emits light, a transparent display area, or an area where a camera, fingerprint recognition unit, face recognition unit, color filter unit, or other functional elements are disposed. Of course, the embodiments of this disclosure include, but are not limited to, the aforementioned at least a portion of the display area may also include other areas besides those described above.

[0095] In some examples, the aforementioned at least partial display area may be a region located near the center of the display substrate. Alternatively, the aforementioned at least partial display area may be a region located near the edge of the display area, such as an edge row or edge column.

[0096] In some examples, the aforementioned at least part of the display area may include 10 rows and 10 columns of subpixels; that is, at least in the display area including 10 rows and 10 columns of subpixels, the third color subpixels have the same shape, the second color subpixels have the same shape, and the first color subpixels have the same shape.

[0097] In some examples, in more than 50% of the display area of ​​the display substrate, the third color subpixels have the same shape, the second color subpixels have the same shape, and the first color subpixels have the same shape.

[0098] FIG. 4 This is a cross-sectional schematic diagram of a display substrate provided in one embodiment of this disclosure. FIG. 4 and FIG. 4 As 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, the pixel defining layer 180 is provided with a plurality of pixel openings 185, 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 pixel opening 185 corresponding to 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 part being disposed in the pixel opening means that the light-emitting part is at least partially disposed in the pixel opening, and the size of the light-emitting part can be larger than the size of the pixel opening; in addition, the above-mentioned light-emitting functional layer can include not only the light-emitting functional layer directly used for light emission, but also auxiliary light emission functional film layers such as hole injection layer, hole transport layer, electron transport layer and electron injection layer.

[0099] In some examples, the display substrate can also define the shape of each sub-pixel by setting a black matrix and black matrix openings. In this case, the shape of the light-emitting part 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 light-emitting part can coincide with or not coincide with the center of the shape of the corresponding pixel opening or black matrix opening.

[0100] In some examples, within a certain sub-pixel, the orthographic projection of the pixel opening onto the substrate has a first shape, and the orthographic projection of the corresponding black matrix opening onto the substrate can be circular. For another example, the orthographic projection of the pixel opening onto the substrate is circular, and the orthographic projection of the corresponding black matrix opening onto the substrate can have the first shape. For yet another example, the center of the orthographic projection of the pixel opening onto the substrate and the center of the orthographic projection of the black matrix opening onto the substrate may or may not coincide.

[0101] In some examples, such as FIG. 4 As shown, in the sub-pixel 230 having a first shape 310, the orthogonal projection of the light-emitting portion 195 onto the substrate 110 is a rounded rectangle 350. The rounded rectangle 350 includes a first rounded corner portion 351 and a second rounded corner portion 352 disposed opposite to each other. The first rounded corner portion 350 is located on the side of the first curved edge 311 away from the second curved edge 312, and the second rounded corner 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 corner portion 351 away from the pixel opening 185 and the first curved edge 311 is smaller than the distance between the second vertex 352P of the second rounded corner portion 352 away from the pixel opening 185 and the second curved edge 312. Since the distance between the first vertex of the first rounded corner portion away from the pixel opening and the first curved edge is smaller than the distance between the second vertex of the second rounded corner portion away from the pixel opening and the second curved edge, the display device can form other functional components such as spacers, fingerprint recognition units, and photosensitive devices at the position where the second curved edge is away from the first curved edge, thereby better integrating other functions onto the display substrate.

[0102] In some examples, in addition to the light-emitting layer 192, the light-emitting functional layer 190 may also include other auxiliary light-emitting films, such as hole injection layers, hole transport layers, electron injection layers, electron transport layers, etc.; at least one of these films may also be patterned to have the same or similar pattern as the light-emitting layer; at least one of these films may also be unpatterned.

[0103] In some examples, such as FIG. 4 As shown, in the sub-pixel 230 having the first shape 310, the rounded rectangle 350 also includes a third rounded corner portion 353 and a fourth rounded corner portion 354 disposed opposite to each other. The line connecting the third vertex 353P of the third rounded corner portion 353 away from the pixel opening 185 and the fourth vertex 354P of the fourth rounded corner portion 354 away from the pixel opening 185 is approximately parallel to the first connecting line CL1.

[0104] In some examples, such as FIG. 4 As shown, multiple sub-pixels 200 can be arranged in a certain pixel arrangement structure array on the substrate 110 for light emission display.

[0105] In some examples, such as FIG. 4 As shown, the 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 a first direction X, and the two second-color sub-pixels 220 are arranged along a second direction Y. The center line connecting the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects with the center line connecting 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 form two independent light-emitting pixels with the first-color sub-pixel 210 and the third-color sub-pixel 230, respectively, thereby achieving higher resolution through the principle of pixel borrowing. It should be noted that the "center line" mentioned above refers to the line connecting the centers of the orthographic projections of the two sub-pixels on the substrate; and the "center" mentioned above can be the brightness center of the sub-pixel or the geometric center of the orthographic projection of the sub-pixel on the substrate. In addition, the shape of the sub-pixel can be the range of the actual effective light-emitting area of ​​the sub-pixel, or it can be the range of the light-emitting area after being limited by some limiting structure or blocking structure.

[0106] In some examples, such as FIG. 4 As shown, the first connecting line CL1 can extend along the first direction X or the second direction Y. Of course, the embodiments of this disclosure include, but are not limited to, the extension direction of the first connecting line is at a certain angle to the first direction X or the second direction Y, for example, the angle between the extension direction of the first connecting line and the first direction X or the second direction Y is in the range of 40-50 degrees.

[0107] In some examples, such as FIG. 4 As shown, the first shape 310 can be an axisymmetric figure. In this case, the axis of symmetry of the first shape 310 can be either the first direction X or the second direction Y as described above.

[0108] In some examples, such as FIG. 4 As shown, the shape of the orthographic projection of the first color sub-pixel 210 onto the substrate 110 can also be an axisymmetric shape, and the shape of the orthographic projection of the second color sub-pixel 220 onto the substrate 110 can also be an axisymmetric shape.

[0109] In some examples, such as FIG. 4As shown, in each sub-pixel group 260, the first center line 410 and the second center line 420 connecting the center of the first color sub-pixel 210 and the centers of the two second color sub-pixels 220, and the third center line 430 and the fourth center line 440 connecting the center of the third color sub-pixel 230 and the centers of the two second color sub-pixels 220, form a first virtual quadrilateral 480, where at least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Therefore, this display substrate can better avoid color separation and can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect.

[0110] In some examples, such as FIG. 4 As shown, the value of one interior angle of the first virtual quadrilateral 480 is between 84 and 94 degrees. For example, one interior angle of the virtual quadrilateral can be 87 degrees, 92 degrees, or 93 degrees.

[0111] In some examples, the first virtual quadrilateral described above can be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of this disclosure include, but are not limited to, the interior angles of the first virtual quadrilateral described above can also be equal to 90 degrees, that is, the first virtual quadrilateral described above is a rectangle.

[0112] In some examples, such as FIG. 4 As shown, the center line connecting 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, where at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Therefore, this display substrate can better avoid color separation and can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve better display effects.

[0113] In some examples, the second virtual quadrilateral described above can be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of this disclosure include, but are not limited to, the interior angles of the second virtual quadrilateral described above can also be equal to 90 degrees, that is, the second virtual quadrilateral described above is a rectangle.

[0114] In some examples, such as FIG. 4As shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 have a first distance D1 and a second distance D2, respectively; the third color sub-pixel 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 size. Therefore, this display substrate can ensure a uniform distribution of each sub-pixel, thereby increasing pixel density while fully utilizing 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 point of the line connecting the centers of the two sub-pixels and the boundary of the two sub-pixels.

[0115] In some examples, such as FIG. 4 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 while fully utilizing the process precision. Of course, embodiments of this disclosure include, but are not limited to, this. For example, the first distance D1 and the second distance D2 are equal, while the third distance D3 and the fourth distance D4 are unequal; or, for another example, the first distance D1, the second distance D2, and the third distance are equal, while the third distance D3 and the fourth distance D4 are unequal.

[0116] In some examples, the ratio of any two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 can range from 0.7 to 1.5.

[0117] In some examples, the ratio of the aperture ratio of the second color sub-pixel 220 to the aperture ratio of the first color sub-pixel 210 ranges from 1 to 1 / 3; the ratio of the aperture ratio of the second color sub-pixel 220 to the aperture ratio of the third color sub-pixel 230 ranges from 1 to 1 / 3; and the ratio of the aperture ratio of the first color sub-pixel 210 to the aperture ratio of the third color sub-pixel 230 ranges from 1 to 1 / 3. Of course, embodiments of this disclosure include, but are not limited to, these examples.

[0118] FIG. 4 This is a schematic diagram of a first shape in another display substrate provided according to an embodiment of the present disclosure; FIG. 4 This is a schematic diagram of a first shape in another display substrate provided according to an embodiment of the present disclosure; FIG. 4 This is a schematic diagram of a first shape in another display substrate provided in an embodiment of the present disclosure.

[0119] In some examples, such as FIG. 2As shown, the first curved edge 311 may include a first inflection point G1, and the bending directions of the first curved edge 311 on both sides of the first inflection point G1 are opposite; for example, the first curved edge 311 may include two first inflection points G1, thereby forming two outwardly protruding curved segments and one inwardly concave curved segment.

[0120] In some examples, such as FIG. 3 As shown, the second curved edge 312 may include a second inflection point G2, and the bending directions of the second curved edge 312 on both sides of the second inflection point G1 are opposite; for example, the second curved edge 312 may include two second inflection points G2, thereby forming two outwardly protruding curved segments and one inwardly concave curved segment.

[0121] In some examples, such as FIG. 4 As shown, the first curved edge 311 may include a first inflection point G1, and the bending directions of the first curved edge 311 on both sides of the first inflection point G1 are opposite; for example, the first curved edge 311 may include two first inflection points G1, thereby forming two outwardly convex curved segments and one inwardly concave curved segment. Meanwhile, the second curved edge 312 may include a second inflection point G2, and the bending directions of the second curved edge 312 on both sides of the second inflection point G1 are opposite; for example, the second curved edge 312 may include two second inflection points G2, thereby forming two outwardly convex curved segments and one inwardly concave curved segment.

[0122] FIG. 4 This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 4 As shown, the display substrate 100 also includes a color filter layer 510, which includes a plurality of color filters 512. The shapes of the plurality of color filters 512 define a plurality of light-emitting regions of a 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 color filter 512 corresponding to the sub-pixel 200 on the substrate 110.

[0123] In some examples, the display substrate is a color filter substrate.

[0124] In some examples, the display substrate includes both light-emitting elements and color filters. The shape of the orthographic projection of each sub-pixel onto 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 image color defining layer opening, and the projection of the pixel-defining layer opening onto the substrate falls within the projection of the corresponding color filter onto the substrate. Alternatively, 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 onto the substrate falls within the projection of the corresponding pixel-defining layer opening onto the substrate.

[0125] In some examples, such as FIG. 4 As shown, the orthographic projection of the color filter 512 corresponding to the first color sub-pixel 210 onto the substrate 110 is circular; the orthographic projection of the color filter 512 corresponding to the second color sub-pixel 220 onto the substrate 110 is circular; and the orthographic projection of the color filter 512 corresponding to the third color sub-pixel 230 onto the substrate 110 is the first shape 310.

[0126] In some examples, such as FIG. 4 As shown, the first and second curved edges of the color filter 512 corresponding to the third color sub-pixel 230 have an arrangement order in the direction perpendicular to the first connecting line CL1. Within the same row of third color sub-pixels, the arrangement order of adjacent third color sub-pixels is opposite, thereby ensuring that the display substrate presents the same display effect under different viewing angles, thus improving display uniformity under different viewing angles. It should be noted that the arrangement order of the first and second curved edges can be found in [reference needed]. FIG. 4 The relevant descriptions will not be repeated here.

[0127] In some examples, such as FIG. 4 As shown, the extension direction of the first line CL1 of the first shape of the filter 512 corresponding to the third color sub-pixel 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 line CL1 of the first shape of the filter 512 corresponding to the third color sub-pixel 230 in the other of the two adjacent third color sub-pixel rows 237 is parallel to the column direction. This can further ensure that the display effect presented by the display substrate is the same under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0128] In some examples, such as FIG. 4As shown, one of the two first lines connecting 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.

[0129] In some examples, such as FIG. 4 As 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, embodiments of this disclosure include, but are not limited to, 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.

[0130] In some examples, such as FIG. 4 As shown, the centers of the plurality of 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 plurality of 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, embodiments of this disclosure include, but are not limited to, these.

[0131] FIG. 1A This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 4 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, the first shape 310 including 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 of the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extension 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 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 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.

[0132] like FIG. 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, with the first straight edge 312C connected to both the first sub-curved edge 312A and the second sub-curved edge 312B. Therefore, this display substrate can also avoid color separation to a certain extent. Furthermore, by setting the aforementioned first curved edge and the second curved edge including the first straight edge, the display substrate can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters, thereby achieving a better display effect. Moreover, the display substrate can also form spacers, fingerprint recognition units, photosensitive devices, and other functional components at positions away from the first curved edge on the first straight edge, thus better integrating other functions onto the display substrate.

[0133] In some examples, such as FIG. 4 As 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 shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is a first shape 310; the plurality of third color sub-pixels 230 are arranged in an array along the row direction and the column direction to form a row of third color sub-pixels 237 extending along the row direction, and the plurality of rows of third color sub-pixels 237 are arranged sequentially 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 the direction perpendicular to the first connecting line CL1, and in the same row of third color sub-pixels 237, the arrangement order of two adjacent third color sub-pixels 230 is opposite. Therefore, within the same row of third color subpixels, the distribution of third color subpixels with different arrangement orders is relatively uniform, which ensures that the display substrate presents the same display effect under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0134] In some examples, such as FIG. 1A As 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 lifespan of the sub-pixel with a lower luminous lifetime can be increased, thereby balancing the lifespan of different sub-pixels.

[0135] For example, the first color can be red, the second color can be green, and the third color can be blue. Of course, the embodiments disclosed herein are not limited to this, and the first, second, and third colors can be other colors.

[0136] In some examples, such as FIG. 4 As shown, the arrangement order of the first curved edge 311 and the second curved 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. Therefore, the distribution of third color sub-pixels with different arrangement orders in the same third color sub-pixel row is relatively uniform, thereby ensuring that the display effect presented by the display substrate is the same under different viewing angles, thus improving the display uniformity under different viewing angles.

[0137] For example, in the same row 237 of third color subpixels, the difference between the number of third color subpixels 230 with the first order and the number of third color subpixels 230 with the second order is less than 2, thereby making the distribution of third color subpixels with different arrangement orders more uniform.

[0138] For example, such as FIG. 4 As shown, in the same third color sub-pixel row 237, the first curved edge 311 and the second curved edge 312 of the first shape 310 of one of two adjacent third color sub-pixels 230 can be along... FIG. 4 Arranged sequentially from left to right, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of two adjacent third color sub-pixels 230 can be... FIG. 5A Arranged sequentially from right to left. For example, such as... FIG. 5A As shown, in the same third color sub-pixel row 237, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of two adjacent third color sub-pixels 230 can be... FIG. 5A Arranged sequentially from top to bottom, the first curved edge 311 and the second curved edge 312 in the first shape 310 of one of the two adjacent third color sub-pixels 230 can be... FIG. 1A Arranged in order from bottom to top.

[0139] In some examples, such as FIG. 5AAs shown, in one of the adjacent rows of third-color sub-pixels 237, the extension direction of the first line CL1 connecting the first shape 310 of the third-color sub-pixels 230 is parallel to the row direction, while the extension direction of the first line CL1 connecting the first shape 310 of the third-color sub-pixels 230 in the other row of third-color sub-pixels 237 is parallel to the column direction. Therefore, by setting the extension direction of the first line connecting the third-color sub-pixels in two adjacent rows of third-color sub-pixels to be parallel to both the row and column directions, the display substrate can further ensure that the display effect presented by the display substrate is the same under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0140] In some examples, such as FIG. 5A As shown, the first straight side 312C can be parallel to the first connecting line CL1. Of course, embodiments of this disclosure include, but are not limited to, the first straight side may also not be parallel to the first connecting line.

[0141] In some examples, such as FIG. 5A As shown, the first shape 310 can be a large circular portion formed by being cut by the first straight line 312C. At this time, the curvature of each point on the first curved edge 311 is the same, the curvature of each point on the first sub-curved edge 312A is the same, and the curvature of each point on the second sub-curved edge 312B is the same. Of course, embodiments of this disclosure include, but are not limited to, this.

[0142] In some examples, such as FIG. 5A As shown, the curvature of each point on the first curved edge 311, the curvature of each point on the first sub-curved edge 312A, and the curvature of each point on the second sub-curved edge 312B are the same.

[0143] In some examples, at least half of the edges on the first curved edge have the same curvature. In some examples, at least half of the edges on the first sub-curved edge have the same curvature. In some examples, at least half of the edges on the second sub-curved edge have the same curvature. In some examples, at least half of the edges on the second curved edge have the same curvature.

[0144] In some examples, such as FIG. 5A As 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 elliptical. Of course, the embodiments of this disclosure include, but are not limited to, other shapes of the first color sub-pixel and the second color sub-pixel.

[0145] In some examples, such as FIG. 5AAs shown, the angle between the extension 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, embodiments of this disclosure include, but are not limited to, the major axis of the ellipse of the second color sub-pixel may also extend along the first direction or the second direction.

[0146] In some examples, such as FIG. 2 As shown, the ellipse of the second color sub-pixel 220 has a dimension in the direction of its major axis that is approximately equal to the diameter of the circle of the first color sub-pixel 210.

[0147] In some examples, such as FIG. 3 As 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 found in [reference needed]. FIG. 5B The relevant description is provided. Of course, the embodiments disclosed herein include, but are not limited to, the display substrate may also be a color filter substrate, as can be found in [reference needed]. FIG. 5C Related descriptions.

[0148] In some examples, such as FIG. 5B As shown, in the sub-pixel 230 having a first shape 310, the orthogonal projection of the light-emitting portion 195 onto the substrate 110 is a rounded rectangle 350. The rounded rectangle 350 includes a first rounded corner portion 351 and a second rounded corner portion 352 disposed opposite to each other. The first rounded corner portion 350 is located on the side of the first curved edge 311 away from the second curved edge 312, and the second rounded corner 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 corner portion 351 away from the pixel opening 185 and the first curved edge 311 is smaller than the distance between the second vertex 352P of the second rounded corner portion 352 away from the pixel opening 185 and the first straight edge 312C. Therefore, the space at the position where the first straight edge is away from the first curved edge is larger, and the display substrate can form spacers, fingerprint recognition units, photosensitive devices, and other functional components at the position where the first straight edge is away from the first curved edge, thereby better integrating other functions onto the display substrate.

[0149] In some examples, such as FIG. 5B As shown, in the sub-pixel 230 having the first shape 310, the rounded rectangle 350 also includes a third rounded corner portion 353 and a fourth rounded corner portion 354 disposed opposite to each other. The line connecting the third vertex 353P of the third rounded corner portion 353 away from the pixel opening 185 and the fourth vertex 354P of the fourth rounded corner portion 354 away from the pixel opening 185 is approximately parallel to the first connecting line CL1.

[0150] In some examples, such as FIG. 5BAs shown, the 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 a first direction X, and the two second-color sub-pixels 220 are arranged along a second direction. The center line connecting the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects with the center line connecting 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 form two independent light-emitting pixels with the first-color sub-pixel 210 and the third-color sub-pixel 230, respectively, thereby achieving a higher resolution through the principle of pixel borrowing.

[0151] In some examples, such as FIG. 5C As shown, multiple first color sub-pixels 210 and multiple third color sub-pixels 230 can be arranged alternately along the first direction X to form a first sub-pixel row 270; multiple second color sub-pixels 220 can be arranged along the first direction X to form a second sub-pixel row 280; multiple first sub-pixel rows 270 and multiple second sub-pixel rows 280 are arranged alternately along the second direction.

[0152] In some examples, such as FIG. 5C As shown, in the first sub-pixel row 270, the center line connecting the first color sub-pixels 210 is a straight line, and the center line connecting the third color sub-pixels 230 is a broken line, and the straight line intersects the broken line. Of course, embodiments of this disclosure include, but are not limited to, the center line connecting the third color sub-pixels may also be a straight line.

[0153] In some examples, such as FIG. 5C As shown, in the second sub-pixel row 280, the center line connecting the second color sub-pixels 220 is a straight line. Of course, embodiments of this disclosure include, but are not limited to, this; the center line connecting the third color sub-pixels can also be a broken line. In some examples, such as... FIG. 5C As shown, the first straight side 312C can be substantially parallel to the second direction. Of course, embodiments of this disclosure include, but are not limited to, the first straight side may also not be parallel to the second direction.

[0154] In some examples, such as FIG. 5C As shown, in the same second sub-pixel row 280, the major axes of the ellipses of two adjacent second color sub-pixels 220 are axially symmetric, for example, axially symmetric about a second direction. For example, in the same second sub-pixel row 280, the angle between the extensions of the major axes of the ellipses of two adjacent second color sub-pixels 220 ranges from 80 to 100 degrees.

[0155] In some examples, such as FIG. 5AAs 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 axially symmetric or mirror symmetric, for example, axially symmetric or mirror symmetric about the first direction X. For example, in the same second sub-pixel row 280, the angle between the extensions of the major axes of the ellipses of two adjacent second color sub-pixels 220 in the second direction Y ranges from 80 to 100 degrees.

[0156] In some examples, such as FIG. 5A As shown, in each sub-pixel group 260, the first and second center lines connecting the center of the first color sub-pixel 210 and the centers of the two second color sub-pixels 220, and the third and fourth center lines connecting the center of the third color sub-pixel 230 and the centers of the two second color sub-pixels 220, form a first virtual quadrilateral, where at least one interior angle of the first virtual quadrilateral is not equal to 90 degrees. Therefore, this display substrate can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect. It should be noted that, for clarity, FIG. 1A The reference numerals for the various center lines are not shown in the attached diagram. The reference numerals for the first, second, third, and fourth center lines can be found in [reference needed]. FIG. 5A .

[0157] In some examples, such as FIG. 5A As shown, the value of one interior angle of the first virtual quadrilateral 480 is between 84 and 94 degrees. For example, one interior angle of the virtual quadrilateral can be 92 degrees.

[0158] In some examples, such as FIG. 5A As shown, the center lines connecting 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, where at least one interior angle is not equal to 90 degrees. Therefore, this display substrate can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect. It should be noted that, for clarity, FIG. 1A The reference numerals for the second virtual quadrilateral are not shown in the accompanying drawings. The reference numerals for the second virtual quadrilateral described above can be found in [reference needed]. FIG. 5A .

[0159] In some examples, such as FIG. 5AAs shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 have a first distance D1 and a second distance D2, respectively; the third color sub-pixel 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 size. Therefore, this display substrate can ensure a uniform distribution of each sub-pixel, thereby increasing pixel density while fully utilizing process precision.

[0160] In some examples, such as FIG. 6A-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 that each sub-pixel is evenly distributed, thereby further improving the pixel density while making full use of the process precision.

[0161] In some examples, such as FIG. 6A As 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 first distance D1, the second distance D2, the third distance D3 and the fourth distance D4 mentioned above.

[0162] FIG. 1A This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 6A 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, the first shape 310 including 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 of the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extension 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 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 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.

[0163] like FIG. 6A The first shape 310 shown is... FIG. 6AThe first shape 310 shown has the same shape, that is, the first curved edge 311 of the first shape 310 is a continuously curved edge, and the second curved edge 312 of the first shape 310 is also a continuously curved edge. Therefore, this display substrate can also avoid color separation to a certain extent, and by setting the aforementioned first and second curved edges, the size and distance of different sub-pixels can be flexibly adjusted according to the luminous efficiency and color index of different color sub-pixels to achieve a better display effect. Furthermore, the display substrate can also form spacers, fingerprint recognition units, photosensitive devices, and other functional components at a position on the second curved edge away from the first curved edge, thereby better integrating other functions onto the display substrate.

[0164] In some examples, such as FIG. 6A As 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 shape of the orthographic projection of the third color sub-pixel 230 on the substrate 110 is a first shape 310; the plurality of third color sub-pixels 230 are arranged in an array along the row direction and the column direction to form a row of third color sub-pixels 237 extending along the row direction, and the plurality of rows of third color sub-pixels 237 are arranged sequentially 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 the direction perpendicular to the first connecting line CL1, and in the same row of third color sub-pixels 237, the arrangement order of two adjacent third color sub-pixels 230 is opposite. Therefore, within the same row of third color subpixels, the distribution of third color subpixels with different arrangement orders is relatively uniform, which ensures that the display substrate presents the same display effect under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0165] In some examples, such as FIG. 6A As 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 elliptical. Of course, the embodiments of this disclosure include, but are not limited to, other shapes of the first color sub-pixel and the second color sub-pixel.

[0166] In some examples, such as FIG. 6A As shown, the ellipse of the second color sub-pixel 220 has a dimension in the direction of its major axis that is approximately equal to the diameter of the circle of the first color sub-pixel 210.

[0167] In some examples, such as FIG. 6AAs shown, in the same second sub-pixel row 280, the major axes of the ellipses of two adjacent second color sub-pixels 220 are axially symmetric or mirror symmetric, for example, axially symmetric or mirror symmetric about the second direction Y.

For example, in the same second sub-pixel row 280, the angle between the extensions of the major axes of the ellipses of two adjacent second color sub-pixels 220 in the second direction Y ranges from 80 to 100 degrees.

[0169] In some examples, such as FIG. 6A As 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 found in [reference needed]. FIG. 6A The relevant description is provided. Of course, the embodiments disclosed herein include, but are not limited to, the display substrate may also be a color filter substrate, as can be found in [reference needed].

The light-emitting functional layer 190 includes a light-emitting layer 192, which includes a plurality of light-emitting portions 195. The plurality of light-emitting portions 195 are disposed within the plurality of pixel openings 185 and are driven and emit light by the plurality of anodes 175 exposed by the pixel openings 185, thereby forming a plurality of light-emitting structures 250 of a plurality of sub-pixels 200. The color filter layer 510 includes a plurality of color filters 512, and the black matrix 550 is disposed between adjacent color filters 512. The color filters 512 are disposed within 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 a black matrix.

[0172] In some examples, such as FIG. 6A As shown, the shape of the orthographic projection of the pixel opening 185 on the substrate 110 can 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 can 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.

The pixel defining layer 180 is provided with a plurality of pixel openings 185. The light-emitting functional layer 190 includes a light-emitting layer 192, which 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 and emit light by the plurality of anodes 175 exposed by the plurality of pixel openings 185, 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, which 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, which is then filtered by the corresponding color filters 512, thereby achieving the emission of light of different colors with high color purity.

[0176] In some examples, the color conversion layer 565 may be a quantum dot layer; of course, embodiments of this disclosure include, but are not limited to, this. Other types of color conversion layers may also be used.

[0178] In some examples, such as FIG. 6B As shown, the display substrate 100 further includes an encapsulation layer 520, an optical adhesive layer 570, and a cover plate 530. The encapsulation 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 encapsulation layer 520 away from the light-emitting functional layer 190 and the substrate 110.

[0179] In some examples, such as FIG. 6B As 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.

[0180] In some examples, such as FIG. 6B As shown, in each sub-pixel group 260, the first center line 410 and the second center line 420 connecting the center of the first color sub-pixel 210 and the centers of the two second color sub-pixels 220, and the third center line 430 and the fourth center line 440 connecting the center of the third color sub-pixel 230 and the centers of the two second color sub-pixels 220, form a first virtual quadrilateral 480, where at least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Therefore, this 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 to achieve a better display effect. It should be noted that, for clarity, FIG. 6B The reference numerals for the various center lines are not shown in the attached diagram. The reference numerals for the first, second, third, and fourth center lines can be found in [reference needed]. FIG. 6A .

[0181] In some examples, such as FIG. 6A As shown, the value of one interior angle of the first virtual quadrilateral 480 is between 84 and 94 degrees. For example, one interior angle of the virtual quadrilateral can be 92 degrees.

[0182] In some examples, such as FIG. 6A As shown, the center lines connecting the two first-color sub-pixels 210 and the 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, where at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Therefore, this display substrate can better avoid color separation and can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect. It should be noted that, for clarity, FIG. 6A The reference numerals for the second virtual quadrilateral are not shown in the accompanying drawings. The reference numerals for the second virtual quadrilateral described above can be found in [reference needed]. FIG. 6A .

[0183] In some examples, such as FIG. 6AAs shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 have a first distance D1 and a second distance D2, respectively; the third color sub-pixel 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 size. Therefore, this display substrate can ensure a uniform distribution of each sub-pixel, thereby increasing pixel density while fully utilizing process precision.

[0184] In some examples, such as FIG. 6A 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 that each sub-pixel is evenly distributed, thereby further improving the pixel density while making full use of the process precision.

[0185] FIG. 2 This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 3 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 onto the substrate 110 includes a first shape 310, the specific description of which can be found in [reference needed]. FIG. 6A The relevant descriptions will not be repeated here.

[0186] like FIG. 6A As shown, the orthographic projection of at least one sub-pixel 200 onto the substrate 110 includes a second shape 320. The second shape 320 includes a third curved edge 321 and a fourth curved edge 322. The two ends of the third curved edge 321 and the two ends of the fourth curved edge 322 are connected to form a third connection point P3 and a fourth connection point P4, respectively. The length of the second line CL2 connecting the third connection point P3 and the fourth connection point P4 is the maximum length of the second shape 320 in the extension direction of the second line CL2. The second shape 320 is divided by the second line CL2 into a third sub-part 320A including the third curved edge 321 and a fourth sub-part 320B including the fourth curved edge 322. The area of ​​the third sub-part 320A is larger than the area of ​​the fourth sub-part 320B. The maximum vertical distance between each point on the third curved edge 321 and the second line CL2 is greater than the maximum vertical distance between each point on the fourth curved edge 322 and the second line CL2. It should be noted that the maximum perpendicular distance between each point on the third curved edge and the second line is the largest of the multiple perpendicular distances between each point on the third curved edge and the second line, and the maximum perpendicular distance between each point on the fourth curved edge and the second line is the largest of the multiple perpendicular distances between each point on the fourth curved edge and the second line.

[0187] In the display substrate provided in this embodiment, based on the first shape of the orthogonal projection of at least one sub-pixel onto the substrate, the shape of the orthogonal projection of at least one sub-pixel onto the substrate also includes a second shape, and the second shape includes a third curved edge and a fourth curved edge. Therefore, the shape of the orthogonal projection of at least one sub-pixel onto the substrate is smoother, thereby mitigating or even avoiding color separation. Furthermore, since the second shape is divided by a second connecting 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 between each point on the third curved edge and the second connecting line is greater than the maximum vertical distance between each point on the fourth curved edge and the second connecting line, the sub-pixel with the second shape can better avoid color separation. Additionally, by setting the aforementioned third and fourth curved edges, 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 to achieve a better display effect. Furthermore, the display substrate can also form spacers, fingerprint recognition units, photosensitive devices, and other functional components at a position on the fourth curved edge away from the third curved edge, thereby allowing for better integration of other functions onto the display substrate. In some examples, such as FIG. 6B As shown, the curvature of the third curved edge 321 away from the vertex of the second line CL2 is greater than the curvature of the fourth curved edge 322 away from the vertex of the second line CL2.

[0188] In some examples, such as FIG. 1A As shown, the third curved edge 321 is a continuously curved edge, and the fourth curved edge 322 is a continuously curved edge.

[0189] In some examples, such as FIG. 6A As shown, the length of the second line CL2 is less than the length of the first 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.

[0190] In some examples, such as FIG. 6A As 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 the first color, the second color sub-pixel 220 is configured to emit light of the second color, and the third color sub-pixel 230 is configured to emit light of the third color.

[0191] In some examples, such as FIG. 6AAs 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 lifespan of the sub-pixel with a lower luminous lifetime can be increased, thereby balancing the lifespan of different sub-pixels.

[0192] For example, the first color can be red, the second color can be green, and the third color can be blue. Of course, the embodiments disclosed herein are not limited to this, and the first, second, and third colors can be other colors.

[0193] In some examples, such as FIG. 6B As shown, 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 row of third color sub-pixels 237 extending along the row direction, and the plurality of third color sub-pixel rows 237 are arranged sequentially 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 the direction perpendicular to the first connecting line CL1, and in the same row of third color sub-pixels 237, the arrangement order of two adjacent third color sub-pixels 230 is opposite; the extension direction of the first connecting line CL1 of the first shape 310 of the third color sub-pixel 230 in one of the two adjacent rows of third color sub-pixels 237 is parallel to the row direction, and the extension direction of the first connecting line CL1 of the first shape 310 of the third color sub-pixel 230 in the other row of three adjacent rows of third color sub-pixels 237 is parallel to the column direction. Therefore, this display substrate allows for a more uniform distribution of third-color sub-pixels with different arrangement orders, thus ensuring the same display effect from different viewing angles and improving display uniformity across different viewing angles. It should be noted that the arrangement order of the first and second curved edges of the aforementioned third-color sub-pixels can be found in [reference needed]. FIG. 1A The relevant descriptions will not be repeated here.

[0194] In some examples, such as FIG. 6A As shown, a plurality of first color sub-pixels 210 are arrayed along the row and column directions to form a row of first color sub-pixels 217 extending along the row direction, and the plurality of first color sub-pixel rows 217 are arranged sequentially along the column direction; the third curved edge 321 and the fourth curved edge 322 of the second shape 320 have an arrangement order in the direction perpendicular to the second connecting line CL2, and in the same row of first color sub-pixels 217, the arrangement order of two adjacent first color sub-pixels 210 is opposite. For example, the row of first color sub-pixels 217 and the row of third color sub-pixels 237 may be the same sub-pixel row.

[0195] In the display substrate provided in this example, since the arrangement order of two adjacent first color sub-pixels in the same first color sub-pixel row is opposite, the distribution of first color sub-pixels with different arrangement orders in the same first color sub-pixel row is relatively uniform, thereby ensuring that the display effect presented by the display substrate is the same under different viewing angles, so as to improve the display uniformity under different viewing angles.

[0196] In some examples, such as FIG. 6B As shown, the arrangement order of the third curved edge 321 and the fourth curved edge 322 includes 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 first color sub-pixels 210 with the third order and the number of first color sub-pixels 210 with the fourth order is less than 10. Therefore, the distribution of first color sub-pixels with different arrangement orders in the same first color sub-pixel row is relatively uniform, thereby ensuring that the display effect presented by the display substrate is the same under different viewing angles, thus improving the display uniformity under different viewing angles.

[0197] For example, in the same first color sub-pixel row 217, the difference between the number of first color sub-pixels 210 with a third order and the number of first color sub-pixels 210 with a fourth order is less than 2, thereby making the first color sub-pixels with different arrangement orders more uniform.

[0198] For example, such as FIG. 6A As shown, in the same first color sub-pixel row 217, the third curved edge 321 and the fourth curved edge 322 in the second shape 320 of one of two adjacent first color sub-pixels 210 can be along... FIG. 6B Arranged sequentially from left to right, the third curved edge 321 and the fourth curved edge 322 in the second shape 320 of one of the two adjacent first color sub-pixels 210 can be... FIG. 6C Arranged sequentially from right to left. For example, such as... FIG. 6C As shown, in the same first color sub-pixel row 217, the third curved edge 321 and the fourth curved edge 322 in the second shape 320 of one of two adjacent first color sub-pixels 210 can be... FIG. 6C Arranged sequentially from top to bottom, the third curved edge 321 and the fourth curved edge 322 in the second shape 320 of one of the two adjacent first color sub-pixels 210 can be... FIG. 6A Arranged in order from bottom to top.

[0199] In some examples, such as FIG. 6DAs shown, in one of the two adjacent first color sub-pixel rows 217, the extension direction of the second line CL2 of the second shape 320 of the first color sub-pixel 210 is parallel to the row direction, and the extension direction of the second line CL2 of the second shape 320 of the first color sub-pixel 210 in the other of the two adjacent first color sub-pixel rows 217 is parallel to the column direction. Therefore, by setting the extension direction of the first line of the third color sub-pixel in two adjacent third color sub-pixel rows to be parallel to both the row and column directions, the display substrate can further ensure that the display effect presented by the display substrate is the same under different viewing angles, thereby improving the display uniformity under different viewing angles.

[0200] In some examples, such as FIG. 6D As shown, the orthographic projection of at least one sub-pixel 200 onto the substrate 110 includes a third shape 330. The third shape 330 includes a fifth curved edge 331 and a sixth curved edge 332. The two ends of the fifth curved edge 331 and the two ends of the sixth curved edge 332 are connected respectively, forming a fifth connection point P5 and a sixth connection point P6. The length of the third connecting 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 extension direction of the third connecting line CL3. The third shape 330 is divided by the third connecting line CL3 into a fifth sub-part 330A including the fifth curved edge 331 and a sixth sub-part 330B including the sixth curved edge 332. The area of ​​the fifth sub-part 330A is equal to the area of ​​the sixth sub-part 330B. The fifth curved edge 331 and the sixth curved edge 332 are arranged axially symmetrically about the third connecting line CL3. Therefore, the orthographic projection of the sub-pixel with the third shape onto the substrate is smoother, thereby reducing or even avoiding color separation. It should be noted that... FIG. 6A-6C The display substrate shown is FIG. 6A-6C The display substrate shown is the same; to better illustrate the relevant features of the third color sub-pixel, FIG. 7 Other figure labels have been omitted.

[0201] In some examples, such as FIG. 7 As shown, the shape of the second color sub-pixel 220 can be elliptical. Of course, embodiments of this disclosure include, but are not limited to, the shape of the second color sub-pixel can also be circular.

[0202] In some examples, as shown in Figure 6B, the fifth curved edge 331 is a continuously curved edge, and the sixth curved edge 332 is a continuously curved edge.

[0203] In some examples, such as FIG. 1A As shown, the length of the third connection CL3 is less than the length of the first connection CL1.

[0204] In some examples, such as FIG. 7 and 6B As shown, when the 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 onto the substrate 110 is a first shape 310, the shape of the orthographic projection of the first color sub-pixel 210 onto the substrate 110 is a second shape 320, and the shape of the orthographic projection of the second color sub-pixel 220 onto the substrate 110 is a third shape 330. Therefore, the shapes of the orthographic projections of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel onto the substrate are smoother, thereby mitigating or even avoiding color separation phenomena.

[0205] In some examples, such as FIG. 7 and 6B As shown, the length of the third line CL3 is equal to the length of the second 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 line CL2.

[0206] In some examples, such as FIG. 7 and 6B As shown, the 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 a first direction X, and the two second-color sub-pixels 220 are arranged along a second direction Y. The center line connecting the first-color sub-pixel 210 and the third-color sub-pixel 230 intersects with the center line connecting 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 form two independent light-emitting pixels with the first-color sub-pixel 210 and the third-color sub-pixel 230, respectively, thereby achieving a higher resolution through the principle of pixel borrowing.

[0207] In some examples, such as FIG. 7 and 6B As shown, multiple first color sub-pixels 210 and multiple third color sub-pixels 230 can be arranged alternately along the first direction X to form a first sub-pixel row 270; multiple second color sub-pixels 220 can be arranged along the first direction X to form a second sub-pixel row 280; multiple first sub-pixel rows 270 and multiple second sub-pixel rows 280 are arranged alternately along the second direction Y.

[0208] In some examples, such as FIG. 2 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 axially symmetric, for example, axially symmetric about the second direction Y. For example, in the same second sub-pixel row 280, the angle between the extensions of the major axes of the ellipses of two adjacent second color sub-pixels 220 ranges from 80 to 100 degrees.

[0209] In some examples, such as FIG. 3 and 6B As 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 Y are axially symmetric, for example, axially symmetric about the first direction X. For example, in the same second sub-pixel row 280, the angle between the extensions of the major axes of the ellipses of two adjacent second color sub-pixels 220 in the second direction Y ranges from 80 to 100 degrees.

[0210] In some examples, such as FIG. 8 and 6B As 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 found in [reference needed]. FIG. 8 The relevant description is provided. Of course, the embodiments disclosed herein include, but are not limited to, the display substrate may also be a color filter substrate, as can be found in [reference needed]. FIG. 1A Related descriptions.

[0211] In some examples, such as FIG. 8 and 6B As shown, in each sub-pixel group 260, the first and second center lines connecting the center of the first color sub-pixel 210 and the centers of the two second color sub-pixels 220, and the third and fourth center lines connecting the center of the third color sub-pixel 230 and the centers of the two second color sub-pixels 220, form a first virtual quadrilateral 480. At least one interior angle of the first virtual quadrilateral 480 is not equal to 90 degrees. Therefore, this display substrate can better avoid color separation and can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect.

[0212] It should be noted that, for clarity, FIG. 9 and FIG. 9 The reference numerals for the various center lines are not shown in the attached diagram. The reference numerals for the first, second, third, and fourth center lines can be found in [reference needed]. FIG. 1A .

[0213] In some examples, such as FIG. 9 and 6BAs shown, the value of one interior angle of the first virtual quadrilateral 480 is between 84 and 94 degrees. For example, one interior angle of the virtual quadrilateral can be 92 degrees.

[0214] In some examples, such as FIG. 10 and 6B As shown, the center lines connecting the two first-color sub-pixels 210 and the 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, where at least one interior angle of the second virtual quadrilateral 490 is not equal to 90 degrees. Therefore, this display substrate can better avoid color separation and can flexibly adjust the size and distance of different sub-pixels according to their luminous efficiency and color parameters to achieve a better display effect. It should be noted that, for clarity, FIG. 10 and FIG. 10 The reference numerals for the second virtual quadrilateral are not shown in the accompanying drawings. The reference numerals for the second virtual quadrilateral described above can be found in [reference needed]. FIG. 10 .

[0215] In some examples, such as FIG. 10 and FIG. 11 As shown, in each sub-pixel group 260, the first color sub-pixel 210 and the two second color sub-pixels 220 have a first distance D1 and a second distance D2, respectively; the third color sub-pixel 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 size. Therefore, this display substrate can ensure a uniform distribution of each sub-pixel, thereby increasing pixel density while fully utilizing process precision.

[0216] In some examples, such as FIG. 11 and FIG. 11 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 that each sub-pixel is evenly distributed, thereby further improving the pixel density while making full use of the process precision.

[0217] FIG. 11 This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 11 As shown, similar to the first shape, the fourth curved edge 322 of the second shape 320 also includes a third sub-curved edge 322A, a fourth sub-curved edge 322B, and a second straight edge 322C. The second straight edge 322C is connected to both the third sub-curved edge 322A and the fourth sub-curved edge 322C. It should be noted that... FIG. 11 The arrangement of the third curved edge 321 and the fourth curved edge 322 of the second shape 320 of the first color sub-pixel 210 can be seen in [reference]. FIG. 11Related descriptions.

[0218] FIG. 12 This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 12 As shown, the orthographic projection of the third color sub-pixel 230 onto the substrate 110 can be a first shape 310; the orthographic projection of the first color sub-pixel 210 onto the substrate 110 can be the second shape 320 described above; and the orthographic projection of the second color sub-pixel 220 onto the substrate 110 can be a circle. It should be noted that the first shape and the second shape described above can be... FIG. 11 In any example, the first and second shapes have the same shape and size, and their arrangement can also be seen in [reference needed]. FIG. 12 The relevant description in any of the examples.

[0219] FIG. 12 This is a plan view of another display substrate provided in an embodiment of the present disclosure. FIG. 13 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 onto the substrate 110 includes a first shape 310, the specific description of which can be found in [reference needed]. FIG. 13 The relevant descriptions will not be repeated here.

[0220] like FIG. 13 As shown, a plurality of sub-pixels 200 are arranged in an array on a substrate 110 to form a display array 290. The plurality of sub-pixels 200 includes boundary sub-pixels 295 located at the edges of the display array 290. The orthographic projection of at least one of the boundary sub-pixels 295 onto the substrate 110 includes a fourth shape 340. The fourth shape 340 includes a seventh curved edge 341 and an eighth curved edge 342. The two ends of the seventh curved edge 341 and the two ends of the eighth curved edge 342 are respectively connected to form a seventh connection point P7 and an eighth connection point P8. The seventh connection point P7... The length of the fourth line CL4 connecting to the eighth connection point P8 is the maximum length of the fourth shape 340 in the extension direction of the fourth line CL4. The fourth shape 340 is divided by the fourth line CL4 into a seventh sub-part 340A including the seventh curved edge 341 and an eighth sub-part 340B including the eighth curved edge 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 edge 341 is the same as the shape of the second curved edge 312, and the shape of the eighth curved edge 342 is the same as the shape of the second curved edge 312. That is to say, relative to the first shape, both curved edges of the fourth shape are recessed.

[0221] In the display substrate provided in this example, based on the fact that the shape of the orthogonal projection of at least one sub-pixel on the substrate includes a first shape, the shape of the orthogonal projection of the boundary sub-pixel on the substrate includes a fourth shape, and the fourth shape includes a seventh curved edge and an eighth curved edge. Therefore, the shape of the orthogonal projection of the boundary sub-pixel on the substrate is more rounded, thereby reducing or even avoiding the occurrence of color separation phenomenon.

[0222] In some examples, such as FIG. 13 As shown, the seventh curved edge 341 is a continuously curved edge, and the eighth curved edge 342 is a continuously curved edge.

[0223] In some examples, such as FIG. 13 As shown, the length of the fourth connection CL4 is equal to the length of the first connection CL1. Therefore, both the boundary sub-pixel 295 and the third color sub-pixel 230 are configured to emit light of the third color.

[0224] In some examples, such as FIG. 13 As 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 found in [reference needed].
