For example, the above "almost" may indicate that the difference between the compared objects is within 10% or 5% of the average value of the compared objects. When the number of one member or element is not specifically indicated in the following contents of the embodiments of the present disclosure, it means that the member or element may be one or may be multiple, or may be understood to be at least one. "At least one" refers to one or multiple, and "multiple" refers to at least two. In the embodiments of the present disclosure, "disposed in the same layer" refers to the relationship between multiple film layers formed by processing the same material in the same step (e.g., one-step patterning process). The "same layer" here does not necessarily mean that the thickness of the multiple film layers is the same, or that the height of the multiple film layers in the cross-sectional view is the same.

[0044] In an organic light emitting diode display device, the light emitting functional layer may not only include a light emitting layer for directly emitting light, but may also include functional film layers for assisting light emission, such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer. During research, the inventors of the present application have found that the current sub-pixels of some shapes (e.g., rectangular) are prone to color separation in certain products or environments.

[0045] In response to this, an embodiment of the present disclosure provides a display substrate and a display device, the display substrate comprising a base substrate and a plurality of sub-pixels disposed on the base substrate, at least one of the sub-pixels having an orthogonal projection shape on the base substrate includes a first shape, the first shape includes a first curved side and a second curved side, both ends of the first curved side and both ends of the second curved side are respectively connected to form a first connection point and a second connection point, a length of a first connection line between the first connection point and the second connection point is a maximum length in an extension direction of the first connection line of the first shape, the first shape is divided by the first connection line into a first sub-portion including the first curved side and a second sub-portion including the second curved side, an area of ​​the first sub-portion is larger than an area of ​​the second sub-portion, and a maximum vertical distance between each point on the first curved side and the first connection line is larger than a maximum vertical distance between each point on the second curved side and the first connection line. As a result, the display substrate can be configured with a shape including curved sides to reduce or even avoid the occurrence of color separation, and further, 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.

[0046] Hereinafter, a display substrate and a display device according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0047] An embodiment of the present disclosure provides a display substrate. FIG. 1A is a schematic plan view of a display substrate according to an embodiment of the present disclosure. As shown in FIG. 1A, the display substrate 100 includes a base substrate 110 and a plurality of sub-pixels 200, the plurality of sub-pixels 200 are located on the base substrate 110, and the shape of at least one of the sub-pixels 200 projected on the base substrate 110 includes a first shape 310, the first shape 310 includes a first curved edge 311 and a second curved edge 312, and both ends of the first curved edge 311 and the second curved edge 312 are connected to each other 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 a 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 a second connection point P2. Thus, the first curved edge 311 and the second curved edge 312 can be surrounded by the outer contour of the first shape 310.

[0048] As shown in FIG. 1A , the length of the first connection line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extension direction of the first connection line CL1, the first shape 310 is divided by the first connection line CL1 into a first sub-portion 310A including a first curved side 311 and a second sub-portion 310B including a second curved side 312, the area of ​​the first sub-portion 310A is larger than the area of ​​the second sub-portion 310B, and the maximum vertical distance between each point on the first curved side 311 and the first connection line CL1 is larger than the maximum vertical distance between each point on the second curved side 312 and the first connection line CL1. Note that the maximum vertical distance between each point on the first curved side and the first connecting line refers to the longest of multiple vertical distances between each point on the first curved side and the first connecting line, while the maximum vertical distance between each point on the second curved side and the first connecting line refers to the longest of multiple vertical distances between each point on the second curved side and the first connecting line.

[0049] In the display substrate according to the embodiment of the present disclosure, the shape of at least one sub-pixel when orthogonally projected on the base substrate includes a first shape, and the first shape includes a first curved edge and a second curved edge, so that the shape of at least one sub-pixel when orthogonally projected on the base substrate is smoother, and thus the occurrence of color separation can be reduced and even avoided. In addition, the first shape is divided by a first connecting line into a first sub-part including the first curved edge and a second sub-part including the second curved edge, and 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 connecting line is larger than the maximum vertical distance between each point on the second curved edge and the first connecting line, so that the sub-pixel having the first shape can better avoid the occurrence of color separation. In addition, by providing the first curved edge and the second curved edge, 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. In addition, the color index may be a parameter such as brightness, color gamut, color temperature, and wavelength of light emitted from the sub-pixel.

[0050] Meanwhile, the maximum vertical distance between each point on the first curved side and the first connecting line is larger than the maximum vertical distance between each point on the second curved side and the first connecting line, so that the space at the position away from the first curved side of the second curved side is relatively large. This allows the display substrate to further form other functional components such as a spacer, a fingerprint recognition unit, a face recognition unit, a photosensitive device, etc. at the position away from the first curved side of the second curved side, so that other functions can be better integrated into the display substrate. In addition, the display substrate can also realize a transparent display region by forming a semi-transparent or transparent region at the position away from the first curved side of the second curved side to allow light to pass through the semi-transparent or transparent region. In addition, a photosensitive device, such as a camera, may be installed on the back side of the semi-transparent or transparent region of the display substrate.

[0051] In some examples, as shown in FIG. 1A, the curvature at the apex of the first curved side 311 away from the first connecting line CL1 is greater than the curvature at the apex of the second curved side 312 away from the first connecting line CL1.

[0052] 1A, the first curved side 311 is a continuously curved side and the second curved side 312 is a continuously curved side. Of course, embodiments of the present disclosure include, but are not limited to, the first curved side may be a discontinuously curved side, for example, may include a short straight portion, and the second curved side may be a discontinuously curved side, for example, may include a short straight portion.

[0053] In some examples, as shown in FIG. 1A , the plurality of subpixels 200 includes a first color subpixel 210, a second color subpixel 220, and a third color subpixel 230, wherein the first color subpixel 210 is configured to emit light of a first color, the second color subpixel 220 is configured to emit light of a second color, and the third color subpixel 230 is configured to emit light of a third color, the shape of the orthogonal projection of the third color subpixel 230 on the base substrate 110 is a first shape 310, the plurality of third color subpixels 230 are arranged in an array along the row direction and the column direction to form a third color subpixel row 237 extending along the row direction, the plurality of third color subpixel rows 237 are sequentially arranged along the column direction, the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in the direction perpendicular to the first connecting line CL1, and the arrangement orders of two adjacent third color subpixels 230 in the same third color subpixel row 237 are reversed.

[0054] In the display substrate of this example, the arrangement orders of two adjacent third color subpixels in the same third color subpixel row are reversed, so that the distribution of third color subpixels with different arrangement orders in the same third color subpixel row is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and thus improving the display uniformity at different viewing angles.

[0055] 1A, the shape of the third color subpixel when orthogonally projected on the base substrate is the first shape; however, embodiments of the present disclosure include, but are not limited to, the above. In some examples, one of the first color subpixel, the second color subpixel, and the third color subpixel has the first shape and the remaining two are circular or elliptical. In some examples, two of the first color subpixel, the second color subpixel, and the third color subpixel have the first shape and the remaining one is circular or elliptical. In some examples, all three of the first color subpixel, the second color subpixel, and the third color subpixel have the first shape.

[0056] In some examples, as shown in FIG. 1A , in the same third color subpixel row 237, the central connection line of the third color subpixels 230 is a broken line, i.e., the centers of the third color subpixels 230 in the third color subpixel row 237 are not located on the same straight line. A plurality of first color subpixels 210 are arranged in an array along the row direction and the column direction to form a first color subpixel row 217 extending along the row direction, and a plurality of first color subpixel rows 217 are sequentially arranged along the column direction. In the same first color subpixel row 217, the central connection line of the first color subpixels 210 is a straight line, i.e., the centers of the first color subpixels 210 in the first color subpixel row 217 are located on the same straight line. In addition, the straight line may cross the broken line. Of course, the embodiments of the present disclosure include, but are not limited to, the above, and the centers of the third color subpixels in the third color subpixel row may be located on the same straight line.

[0057] 1A , the area of ​​the third color subpixel 230 is larger than the area of ​​the first color subpixel 210, and the area of ​​the third color subpixel 230 is larger than the area of ​​the second color subpixel 210. By setting the area of ​​the subpixel with a relatively short emission lifetime to be larger, the service lifetime of the subpixel with a relatively short emission lifetime can be extended, thereby balancing the service lifetime of different subpixels.

[0058] 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 have less light loss in the light-emitting process than other sub-pixels, by appropriately reducing the area thereof, the area of other sub-pixels with relatively more light loss can be increased as much as possible. For example, in a display device with light conversion, the area of sub-pixels with relatively low light conversion efficiency is smaller than the area of sub-pixels with relatively high light conversion efficiency. For example, in a display device with light conversion, the area of sub-pixels that do not require light conversion is smaller than the area of sub-pixels that require light conversion.

[0059] In some embodiments, the shape and area of each color sub-pixel may refer to the shape and area of the portion for light emission. For example, the shape and area of each sub-pixel may be the shape and area defined by the pixel aperture of the pixel defining layer. The pixel defining layer is disposed on the side away from the base substrate of one electrode of the light-emitting diode and includes at least a part of the electrode. The light-emitting functional layer is formed in the aperture of the pixel defining layer, and another electrode of the light-emitting diode is further disposed on the side away from the base substrate of the light-emitting functional layer.

[0060] In some embodiments, the shape and area of each color sub-pixel may refer to the shape and area of the portion for light output. For example, the shape and area of each sub-pixel may be the shape and area of the filter layer that correspondingly transmits each color in the color filter layer, for example, the shape and area of the aperture 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, the embodiments of the present disclosure include the above, but are not limited thereto, and the first color, the second color, and the third color may be other colors.

[0061] 1A , the arrangement orders of the first curved edge 311 and the second curved edge 312 include a first order and a second order that are reversed to each other, and in the same third color subpixel row 237, a difference between the number of third color subpixels 230 having the first order and the number of third color subpixels 230 having the second order is less than 10. Thereby, in the same third color subpixel row 237, the distribution of third color subpixels having different arrangement orders is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0062] For example, in the same third color subpixel row 237, the difference between the number of third color subpixels 230 having the first order and the number of third color subpixels 230 having the second order is less than 2, thereby making the distribution of third color subpixels having different arrangement orders relatively uniform.

[0063] For example, as shown in FIG. 1A , in the same third color subpixel row 237, in the first shape 310 of one of two adjacent third color subpixels 230, the first curved side 311 and the second curved side 312 may be arranged sequentially along the left-to-right direction in FIG. 1A , and in the first shape 310 of the other of the two adjacent third color subpixels 230, the first curved side 311 and the second curved side 312 may be arranged sequentially along the right-to-left direction in FIG. 1A . Further, for example, as shown in FIG. 1A , in the same third color subpixel row 237, the first curved side 311 and the second curved side 312 in the first shape 310 of one of two adjacent third color subpixels 230 may be arranged sequentially along a top-to-bottom direction in FIG. 1A , and the first curved side 311 and the second curved side 312 in the first shape 310 of the other of the two adjacent third color subpixels 230 may be arranged sequentially along a bottom-to-top direction in FIG. 1A .

[0064] 1A , the extension direction of the first connecting lines CL1 of the first shapes 310 of the third color subpixels 230 in one of two adjacent third color subpixel rows 237 is parallel to the row direction, and the extension direction of the first connecting lines CL1 of the first shapes 310 of the third color subpixels 230 in the other of the two adjacent third color subpixel rows 237 is parallel to the column direction. Thus, by setting the extension directions of the first connecting lines of the third color subpixels in the two adjacent third color subpixel rows 237 to be parallel to the row direction and the column direction, respectively, the display substrate can further ensure that the display effects displayed by the display substrate at different viewing angles are the same, and further improve the display uniformity at different viewing angles.

[0065] 1A, the first color subpixel 210 may be circular in shape, and the second color subpixel 220 may be circular in shape. Of course, the embodiments of the present disclosure include, but are not limited to, the first color subpixel shape and the second color subpixel shape may also be elliptical or rectangular with rounded corners.

[0066] 1A, the area of ​​the first color subpixel 210 is larger than the area of ​​the second color subpixel 220. By setting the area of ​​the subpixel having a shorter emission lifetime among the first color subpixel and the second color subpixel to be larger, the service life of the subpixel having a shorter emission lifetime can be extended, thereby balancing the service life of different subpixels.

[0067] In some examples, as shown in FIG. 1A, in at least a part of the display area of ​​the display substrate, the third color subpixels 230 have the same shape, the second color subpixels 220 have the same shape, and the first color subpixels 210 have the same shape. Note that the at least a part of the display area may be an area having a similar pixel driving method or similar display requirements, such as an area of ​​the display substrate that performs light-emitting display, a transparent display area, or an area where a camera, a fingerprint recognition unit, a face recognition unit, a color film unit, or other functional elements are installed. Of course, the embodiments of the present disclosure include, but are not limited to, the at least a part of the display area may further include other areas other than the above areas.

[0068] In some examples, the at least a portion of the display area may be an area proximate a center of the display substrate.Further for example, the at least a portion of the display area may be an area proximate an edge of the display area, such as an edge row or an edge column.

[0069] In some examples, at least a portion of the display area may include 10 rows and 10 columns of subpixels, i.e., in a display area including at least 10 rows and 10 columns of subpixels, each third color subpixel has the same shape, each second color subpixel has the same shape, and each first color subpixel has the same shape.

[0070] In some examples, in 50% or more of a display area of ​​the display substrate, each of the third color subpixels has the same shape, each of the second color subpixels has the same shape, and each of the first color subpixels has the same shape.

[0071] FIG. 2 is a schematic cross-sectional view of a display substrate according to an embodiment of the present disclosure. 1A and 2, the display substrate 100 further includes a plurality of anodes 175, a pixel limiting layer 180, and a light-emitting functional layer 190, where the plurality of anodes 175 are disposed on the base substrate 110, the pixel limiting layer 180 is disposed on the base substrate 110, the light-emitting functional layer 190 is disposed on the side of the plurality of anodes 175 and the pixel limiting layer 180 away from the base substrate 110, a plurality of pixel openings 185 are disposed on the pixel limiting layer 180, the light-emitting functional layer 190 includes a light-emitting layer 192, the light-emitting layer 192 includes a plurality of light-emitting portions 195, the plurality of light-emitting portions 195 are disposed in the plurality of pixel openings 185, and are driven by the plurality of anodes 175 exposed from the plurality of pixel openings 185 to form a plurality of light-emitting structures 250 of a plurality of sub-pixels 200, and the shape of the orthogonal projection of each sub-pixel 200 on the base substrate 110 is the shape of the orthogonal projection of the pixel opening 185 corresponding to the sub-pixel 200 on the base substrate 110. That is, the display substrate may be an array substrate for display. In addition, the light-emitting portion being disposed in the pixel opening means that at least a portion of the light-emitting portion is disposed in the pixel opening, and the dimensions of the light-emitting portion may be larger than the dimensions of the pixel opening. Furthermore, the light-emitting functional layer may not only include a light-emitting functional layer for directly emitting light, but may further include functional film layers that assist light emission, such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer.

[0072] In some examples, the display substrate may define the shape of each sub-pixel by providing a black matrix and a black matrix opening, in which the shape of the light-emitting portion may be the same as or different from the shape of the corresponding pixel opening or black matrix opening, and the center of the shape of the light-emitting portion may or may not overlap with the center of the shape of the corresponding pixel opening or black matrix opening.

[0073] In some examples, for a subpixel, the shape of the orthogonal projection of the pixel aperture on the base substrate may have a first shape, and the shape of the orthogonal projection of the corresponding black matrix opening on the base substrate may be circular.Further for example, the shape of the orthogonal projection of the pixel aperture on the base substrate may be circular, and the shape of the orthogonal projection of the corresponding black matrix opening on the base substrate may be a first shape.Further for example, the shape of the orthogonal projection of the pixel aperture on the base substrate may or may not overlap with the center of the orthogonal projection of the black matrix opening on the base substrate.

[0074] In some examples, as shown in FIG. 1A , in a subpixel 230 having a first shape 310, the shape of the orthogonal projection of the light-emitting portion 195 on the base substrate 110 is a rounded rectangle 350, and the rounded rectangle 350 includes a first rounded corner 351 and a second rounded corner 352 arranged opposite each other, the first rounded corner 350 is located on the side of the first curved side 311 that is away from the second curved side 312, and the second rounded corner 352 is located on the side of the second curved side 312 that is away from the first curved side 311, and the distance between a first vertex 351P of the first rounded corner 351 that is away from the pixel opening 185 and the first curved side 311 is smaller than the distance between a second vertex 352P of the second rounded corner 352 that is away from the pixel opening 185 and the second curved side 312. Since the distance between the first vertex away from the pixel opening of the first round corner portion and the first curved side is smaller than the distance between the second vertex away from the pixel opening of the second round corner portion and the second curved side, the display device can form other functional components such as spacers, fingerprint recognition units, photosensitive devices, etc. at a position away from the first curved side of the second curved side, so that other functions can be better integrated into the display substrate.

[0075] In some examples, in addition to the light-emitting layer 192, the light-emitting functional layer 190 may further include other film layers that assist in light emission, such as a hole injection layer, a hole transport layer, an electron injection layer, an electron transport layer, etc., at least one of which may have a pattern that is the same or similar to the light-emitting layer by patterning, or at least one of which may not be patterned.

[0076] In some examples, as shown in FIG. 1A , in a subpixel 230 having the first shape 310, the rounded rectangle 350 further includes a third rounded corner 353 and a fourth rounded corner 354 arranged opposite each other, and a connection line between a third vertex 353P of the third rounded corner 353 away from the pixel opening 185 and a fourth vertex 354P of the fourth rounded corner 354 away from the pixel opening 185 is approximately parallel to the first connection line CL1.

[0077] In some examples, as shown in FIG. 1A, a plurality of sub-pixels 200 may be arranged in an array on the base substrate 110 according to a certain pixel array structure, thereby facilitating light-emitting display.

[0078] 1A , the plurality of subpixels 200 includes a plurality of subpixel groups 260, each of which includes one first color subpixel 210, two second color subpixels 220, and one third color subpixel 230, and in each subpixel group 260, the first color subpixel 210 and the third color subpixel 230 are arranged along a first direction X, and the two second color subpixels 220 are arranged along a second direction Y, and the central connecting lines of the first color subpixel 210 and the third color subpixel 230 intersect with the central connecting lines of the two second color subpixels 220. When the display substrate according to the example is used for display, the two second color subpixels 220 in one pixel group can respectively constitute two independent light-emitting pixel points together with the first color subpixel 210 and the third color subpixel 230, thereby achieving higher resolution through the principle of pixel borrowing. The "center connecting line" refers to the connecting line of the centers of the orthogonal projections of two subpixels on the base substrate, but the "center" may be the luminance center of the subpixel or the geometric center of the orthogonal projection of the subpixel on the base substrate. The shape of the subpixel may be the range of the actual effective light-emitting area of ​​the subpixel, or may be the range of the light-emitting area limited by some limiting or shielding structures.

[0079] 1A, the first connecting line CL1 may extend along the first direction X or the second direction Y. Of course, the embodiments of the present disclosure include, but are not limited to, the extending direction of the first connecting line and the first direction X or the second direction Y form a certain angle, for example, the included angle between the extending direction of the first connecting line and the first direction X or the second direction Y is in the range of 40 to 50 degrees.

[0080] In some examples, the first shape 310 may be an axisymmetric figure, as shown in Figure 1A. In this case, the axis of symmetry of the first shape 310 may be the first direction X or the second direction Y.

[0081] In some examples, as shown in FIG. 1A, the shape of the orthogonal projection of the first color subpixel 210 on the base substrate 110 may be an axially symmetric figure, and the shape of the orthogonal projection of the second color subpixel 220 on the base substrate 110 may be an axially symmetric figure.

[0082] 1A , in each subpixel group 260, a first central connecting line 410 and a second central connecting line 420 between the center of the first color subpixel 210 and the centers of the two second color subpixels 220, and a third central connecting line 430 and a fourth central connecting line 440 between the center of the third color subpixel 230 and the centers of the two second color subpixels 220 form a first virtual rectangle 480, in which at least one interior angle is not equal to 90 degrees, so that the display substrate can better avoid the occurrence of color separation phenomenon, and can further flexibly adjust the size and distance of different subpixels according to the luminous efficiency and color index of different color subpixels to achieve a better display effect.

[0083] 1A, the value range of one interior angle of the first imaginary rectangle 480 is 84 to 94 degrees. For example, one interior angle of the imaginary rectangle may be 87 degrees, 92 degrees, and 93 degrees.

[0084] In some examples, the first imaginary rectangle may be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of the present disclosure include, but are not limited to, the interior angles of the first imaginary rectangle may be equal to 90 degrees, that is, the first imaginary rectangle is a rectangle.

[0085] 1A , the central connecting lines of two first color subpixels 210 and two third color subpixels 230 in two subpixel groups 260 adjacent to each other in the second direction may form a second imaginary rectangle 490, in which at least one interior angle of the second imaginary rectangle 490 is not equal to 90 degrees, so that the display substrate can better avoid the occurrence of color separation phenomenon, and further, the size and distance of different subpixels can be flexibly adjusted according to the luminous efficiency and color index of different color subpixels to achieve a better display effect.

[0086] In some examples, the second imaginary rectangle may be a parallelogram, a rhombus, or a trapezoid. Of course, the embodiments of the present disclosure include, but are not limited to, the interior angles of the second imaginary rectangle may be equal to 90 degrees, that is, the second imaginary rectangle is a rectangle.

[0087] In some examples, as shown in FIG. 1A, in each subpixel group 260, the first color subpixel 210 and the two second color subpixels 220 have a first distance D1 and a second distance D2, and the third color subpixel 230 and the two second color subpixels 220 have a third distance D3 and a fourth distance D4, and at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal in magnitude. This allows the display substrate to ensure a uniform distribution of each subpixel, thereby improving pixel density under the premise of making full use of process precision. For example, the distance between two subpixels is the distance at which the boundaries of the two subpixels are closest. For example, the distance between two subpixels is the distance between the connecting line passing through the centers of the two subpixels and the intersection point of the boundaries of the two subpixels.

[0088] In some examples, as shown in FIG. 1A, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal, which further ensures the uniform distribution of each sub-pixel, and thus further improves the pixel density under the premise of fully utilizing the process precision. Of course, the embodiments of the present disclosure include, but are not limited to, the above. For example, the first distance D1 and the second distance D2 are equal, and the third distance D3 and the fourth distance D4 are not equal, and further, for example, the first distance D1, the second distance D2, and the third distance are equal, and the third distance D3 and the fourth distance D4 are not equal.

[0089] In some examples, the range of the ratio between any two values ​​of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 may be 0.7 to 1.5.

[0090] In some examples, the ratio of the aperture ratio of the second color subpixel 220 to the aperture ratio of the first color subpixel 210 is in a range of 1 to 1 / 3, the ratio of the aperture ratio of the second color subpixel 220 to the aperture ratio of the third color subpixel 230 is in a range of 1 to 1 / 3, and the ratio of the aperture ratio of the first color subpixel 210 to the third color subpixel 230 is in a range of 1 to 1 / 3. Obviously, the embodiments of the present disclosure include, but are not limited to, the above.

[0091] FIG. 1B is a schematic diagram of a first shape in another display substrate according to one embodiment of the present disclosure, FIG. 1C is a schematic diagram of a first shape in another display substrate according to one embodiment of the present disclosure, and FIG. 1D is a schematic diagram of a first shape in another display substrate according to one embodiment of the present disclosure.

[0092] In some examples, as shown in FIG. 1B , the first curved edge 311 may include a first inflection point G1, and the first curved edge 311 may have opposite curvature directions on either side of the first inflection point G1, for example, the first curved edge 311 may include two first inflection points G1, thereby forming two outwardly protruding curved line segments and one inwardly concave curved line segment.

[0093] In some examples, as shown in FIG. 1C , the second curved side 312 may include a second inflection point G2, and the direction of curvature on either side of the second inflection point G1 of the second curved side 312 is opposite, for example, the second curved side 312 may include two second inflection points G2, thereby forming two outwardly protruding curved line segments and one inwardly concave curved line segment.

[0094] In some examples, as shown in FIG. 1D , the first curved edge 311 may include a first inflection point G1, and the first curved edge 311 has opposite curvature directions on both sides of the first inflection point G1, for example, the first curved edge 311 may include two first inflection points G1, thereby forming two outwardly protruding curved line segments and one inwardly concave curved line segment. At the same time, the second curved edge 312 may include a second inflection point G2, and the second curved edge 312 has opposite curvature directions on both sides of the second inflection point G1, for example, the second curved edge 312 may include two second inflection points G2, thereby forming two outwardly protruding curved line segments and one inwardly concave curved line segment.

[0095] 3 is a schematic plan view of another display substrate according to an embodiment of the present disclosure. As shown in FIG. 3, the display substrate 100 further includes a color film layer 510, which includes a plurality of color filters 512, the shapes of which define a plurality of light emitting areas of a plurality of sub-pixels 200, and the shape of each sub-pixel 200 projected on the base substrate 110 is the shape of the color filter 512 corresponding to the sub-pixel 200 projected on the base substrate 110.

[0096] In some instances, the display substrate is a color film substrate.

[0097] In some examples, the display substrate is a display substrate including a light-emitting element and a color filter at the same time, and the shape of the orthogonal projection of each subpixel on the base substrate is the shape of an opening of the pixel limiting layer corresponding to the light-emitting element and a corresponding color filter overlapping in a direction perpendicular to the base substrate. For example, the shape of an opening of the pixel limiting layer corresponding to the light-emitting element and a corresponding color filter overlapping in a direction perpendicular to the base substrate is the shape of the opening of the pixel limiting layer, and the projection of the opening of the pixel limiting layer on the base substrate is within the projection of the corresponding color filter on the base substrate. For example, the shape of an opening of the pixel limiting layer corresponding to the light-emitting element and a corresponding color filter overlapping in a direction perpendicular to the base substrate is the shape of the color filter, and the projection of the color filter on the base substrate is within the projection of the opening of the corresponding pixel limiting layer on the base substrate.

[0098] In some examples, as shown in FIG. 3, the shape of the orthogonal projection of the color filter 512 corresponding to the first color subpixel 210 on the base substrate 110 is circular, the shape of the orthogonal projection of the color filter 512 corresponding to the second color subpixel 220 on the base substrate 110 is circular, and the shape of the orthogonal projection of the color filter 512 corresponding to the third color subpixel 230 on the base substrate 110 is the first shape 310.

[0099] In some examples, as shown in Fig. 3, the first and second curved sides of the color filters 512 corresponding to the third color subpixels 230 have an arrangement order in a direction perpendicular to the first connecting line CL1, and the arrangement orders of two adjacent third color subpixels in the same third color subpixel row are reversed, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and improving the display uniformity at different viewing angles. Note that the arrangement order of the first and second curved sides may refer to the related description of Fig. 1A, and detailed description thereof will be omitted here.

[0100] In some examples, as shown in FIG. 3 , the extension direction of the first connecting line CL1 of the first shape of the filter 512 corresponding to the third color subpixel 230 in one of the two adjacent third color subpixel rows 237 is parallel to the row direction, and the extension direction of the first connecting line CL1 of the first shape of the filter 512 corresponding to the third color subpixel 230 in the other of the two adjacent third color subpixel rows 237 is parallel to the column direction, thereby further ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and further improving the display uniformity at different viewing angles.

[0101] In some examples, as shown in FIG. 3, one of the two first connecting lines of the first shape of the filter 512 corresponding to two third color subpixels 230 adjacent to one second color subpixel 220 is parallel to the row direction and the other is parallel to the column direction.

[0102] 3, the length of the first connecting line of the first shape of the filter 512 corresponding to the third color subpixel 230 is larger than the diameter of the filter 512 corresponding to the first color subpixel 210 and the diameter of the filter 512 corresponding to the second color subpixel 220. Of course, the embodiments of the present 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 subpixel may be smaller than the diameter of the filter corresponding to the first color subpixel and larger than the diameter of the filter corresponding to the second color subpixel.

[0103] 3, the centers of the third color sub-pixels 230 arranged in the first direction X are located on a straight line extending along the first direction X, and the centers of the third color sub-pixels 230 arranged in the second direction Y are located on a straight line extending along the second direction Y. Of course, the embodiments of the present disclosure include, but are not limited to, the above.

[0104] 4 is a schematic plan view of another display substrate according to an embodiment of the present disclosure. As shown in FIG. 4, the display substrate 100 includes a base substrate 110 and a plurality of sub-pixels 200, the sub-pixels 200 are located on the base substrate 110, and the orthogonal projection shape of at least one of the sub-pixels 200 on the base substrate 110 includes a first shape 310, the first shape 310 includes a first curved edge 311 and a second curved edge 312, and both ends of the first curved edge 311 and the second curved edge 312 are respectively connected to form a first connection point P1 and a second connection point P2. The length of the first connection line CL1 between the first connection point P1 and the second connection point P2 is the maximum length of the first shape 310 in the extension direction of the first connection line CL1, the first shape 310 is divided by the first connection line CL1 into a first sub-portion 310A including the first curved side 311 and a second sub-portion 310B including the second curved side 312, the area of ​​the first sub-portion 310A is larger than the area of ​​the second sub-portion 310B, and the maximum vertical distance between each point on the first curved side 311 and the first connection line CL1 is larger than the maximum vertical distance between each point on the second curved side 312 and the first connection line CL1.

[0105] As shown in FIG. 4, in the first shape 310, the first curved edge 311 is a continuous 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, and the first straight edge 312C is connected to the first sub-curved edge 312A and the second sub-curved edge 312B, respectively. This allows the display substrate to avoid the occurrence of color separation to a certain extent. In addition, the display substrate can flexibly adjust the size and distance of different sub-pixels according to the luminous efficiency and color index of different color sub-pixels by providing the second curved edge including the first curved edge and the first straight edge, thereby achieving a better display effect. In addition, the display substrate can further form other functional components such as spacers, fingerprint recognition units, photosensitive devices, etc. at a position away from the first curved edge of the first straight edge, so that other functions can be better integrated into the display substrate.

[0106] In some examples, as shown in FIG. 4 , the plurality of subpixels 200 includes a first color subpixel 210, a second color subpixel 220, and a third color subpixel 230, wherein the first color subpixel 210 is configured to emit light of a first color, the second color subpixel 220 is configured to emit light of a second color, and the third color subpixel 230 is configured to emit light of a third color, the shape of the orthogonal projection of the third color subpixel 230 on the base substrate 110 is a first shape 310, the plurality of third color subpixels 230 are arranged in an array along the row direction and the column direction to form a third color subpixel row 237 extending along the row direction, the plurality of third color subpixel rows 237 are sequentially arranged along the column direction, the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in the direction perpendicular to the first connecting line CL1, and the arrangement orders of two adjacent third color subpixels 230 in the same third color subpixel row 237 are reversed. Therefore, in the same third color subpixel row, the distribution of third color subpixels having different arrangement orders is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and thus improving the display uniformity at different viewing angles.

[0107] 4, the area of ​​the third color subpixel 230 is larger than the area of ​​the first color subpixel 210, and the area of ​​the third color subpixel 230 is larger than the area of ​​the second color subpixel 210. By setting the area of ​​the subpixel with a relatively short emission lifetime to be larger, the service life of the subpixel with a relatively short emission lifetime can be extended, thereby balancing the service life of different subpixels.

[0108] For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include, but are not limited to, the first color, the second color, and the third color may be other colors.

[0109] 4 , the arrangement orders of the first curved edges 311 and the second curved edges 312 include a first order and a second order that are reversed to each other, and in the same third color subpixel row 237, a difference between the number of third color subpixels 230 having the first order and the number of third color subpixels 230 having the second order is less than 10. Thereby, in the same third color subpixel row 237, the distribution of third color subpixels having different arrangement orders is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0110] For example, in the same third color subpixel row 237, the difference between the number of third color subpixels 230 having the first order and the number of third color subpixels 230 having the second order is less than 2, thereby making the distribution of the third color subpixels having different arrangement orders more uniform.

[0111] For example, as shown in FIG. 4 , in the same third color subpixel row 237, in the first shape 310 of one of two adjacent third color subpixels 230, the first curved side 311 and the second curved side 312 may be arranged sequentially along the left-to-right direction in FIG. 4 , and in the first shape 310 of the other of the two adjacent third color subpixels 230, the first curved side 311 and the second curved side 312 may be arranged sequentially along the right-to-left direction in FIG. 4 . Further, for example, as shown in FIG. 4, in the same third color subpixel row 237, the first curved side 311 and the second curved side 312 in the first shape 310 of one of two adjacent third color subpixels 230 may be arranged sequentially along a top-to-bottom direction in FIG. 4, and the first curved side 311 and the second curved side 312 in the first shape 310 of the other of the two adjacent third color subpixels 230 may be arranged sequentially along a bottom-to-top direction in FIG. 4.

[0112] 4 , the extension direction of the first connecting lines CL1 of the first shapes 310 of the third color subpixels 230 in one of two adjacent third color subpixel rows 237 is parallel to the row direction, and the extension direction of the first connecting lines CL1 of the first shapes 310 of the third color subpixels 230 in the other of the two adjacent third color subpixel rows 237 is parallel to the column direction. Thus, by setting the extension directions of the first connecting lines of the third color subpixels in the two adjacent third color subpixel rows 237 to be parallel to the row direction and the column direction, respectively, the display substrate can further ensure that the display effects displayed by the display substrate at different viewing angles are the same, and further improve the display uniformity at different viewing angles.

[0113] In some examples, the first straight side 312C may be parallel to the first connecting line CL1, as shown in Fig. 4. Of course, the embodiments of the present disclosure include, but are not limited to, the first straight side may not be parallel to the first connecting line.

[0114] In some examples, as shown in Fig. 4, the first shape 310 may be a circular portion having a relatively large area cut by the first straight line 312C. In this case, the curvature at each point on the first curved side 311 is the same, the curvature at each point on the first sub-curved side 312A is the same, and the curvature at each point on the second sub-curved side 312B is the same. Of course, the embodiments of the present disclosure include, but are not limited to, the above.

[0115] In some examples, as shown in FIG. 4, the curvature at each point on the first curved side 311, the curvature at each point on the first sub-curved side 312A, and the curvature at each point on the second sub-curved side 312B are the same.

[0116] In some examples, at least half of the first curved side has the same curvature. In some examples, at least half of the first sub-curved side has the same curvature. In some examples, at least half of the second sub-curved side has the same curvature. In some examples, at least half of the second sub-curved side has the same curvature.

[0117] In some examples, the first color subpixel 210 may be circular in shape and the second color subpixel 220 may be elliptical in shape, as shown in Figure 4. Of course, the embodiments of the present disclosure include, but are not limited to, the first color subpixel and the second color subpixel may have other shapes.

[0118] 4, the angle between the extension direction of the major axis of the ellipse of the second color subpixel 220 and the first direction X or the second direction Y is less than 90 degrees, for example, 30 to 60 degrees. Of course, the embodiments of the present disclosure include, but are not limited to, the major axis of the ellipse of the second color subpixel may extend along the first direction or the second direction.

[0119] In some examples, as shown in FIG. 4, the dimension along the major axis of the ellipse of the second color subpixel 220 is approximately equal to the diameter of the circle of the first color subpixel 210 .

[0120] In some examples, as shown in Fig. 4, the display substrate 100 may be an array substrate for display, and the lamination relationship of the anode, the pixel definition layer and the light-emitting functional layer in the array substrate in the direction perpendicular to the base substrate may refer to the related description of Fig. 2.

[0121] In some examples, as shown in FIG. 4, in a subpixel 230 having a first shape 310, the shape of the orthogonal projection of the light-emitting portion 195 on the base substrate 110 is a rounded rectangle 350, and the rounded rectangle 350 includes a first rounded corner 351 and a second rounded corner 352 arranged opposite each other, the first rounded corner 350 is located on the side of the first curved side 311 that is away from the second curved side 312, and the second rounded corner 352 is located on the side of the second curved side 312 that is away from the first curved side 311, and the distance between a first vertex 351P of the first rounded corner 351 that is away from the pixel opening 185 and the first curved side 311 is smaller than the distance between a second vertex 352P of the second rounded corner 352 that is away from the pixel opening 185 and the first straight side 312C. As a result, the space away from the first curved side of the first straight side is relatively large, and the display substrate can form other functional components such as spacers, fingerprint recognition units, photosensitive devices, etc. at the position away from the first curved side of the first straight side, thereby better integrating other functions into the display substrate.

[0122] In some examples, as shown in FIG. 4, in a subpixel 230 having the first shape 310, the rounded rectangle 350 further includes a third rounded corner 353 and a fourth rounded corner 354 arranged opposite each other, and a connection line between a third vertex 353P of the third rounded corner 353 away from the pixel opening 185 and a fourth vertex 354P of the fourth rounded corner 354 away from the pixel opening 185 is approximately parallel to the first connection line CL1.

[0123] 4, the subpixels 200 include a plurality of subpixel groups 260, each of which includes one first color subpixel 210, two second color subpixels 220, and one third color subpixel 230, and in each subpixel group 260, the first color subpixel 210 and the third color subpixel 230 are arranged along a first direction X, and the two second color subpixels 220 are arranged along a second direction, and the central connecting lines of the first color subpixel 210 and the third color subpixel 230 intersect with the central connecting lines of the two second color subpixels 220. When the display substrate according to this example is used for display, the two second color subpixels 220 in one pixel group can respectively constitute two independent light-emitting pixel points together with the first color subpixel 210 and the third color subpixel 230, thereby achieving higher resolution through the principle of pixel borrowing.

[0125] 4, in the first subpixel row 270, the central connecting line of the first color subpixels 210 is a straight line, and the central connecting line of the third color subpixels 230 is a broken line, and the straight line intersects with the broken line. Of course, the embodiments of the present disclosure include, but are not limited to, the central connecting line of the third color subpixels may be a straight line.

[0127] 4, the major axes of the ellipses of two adjacent second-color subpixels 220 in the same second subpixel row 280 are axially symmetric, e.g., axially symmetric with respect to the second direction. For example, the included angle between the extensions of the major axes of the ellipses of two adjacent second-color subpixels 220 in the same second subpixel row 280 is in the range of 80 to 100 degrees.

[0128] 4, in two adjacent second subpixel rows 280, the major axes of the ellipses of two second color subpixels 220 adjacent in the second direction are axially symmetric or mirror-symmetric, for example, axially symmetric or mirror-symmetric with respect to the first direction X. For example, in the same second subpixel row 280, the included angle between the extensions of the major axes of the ellipses of two second color subpixels 220 adjacent in the second direction Y is in the range of 80 to 100 degrees.

[0129] In some examples, as shown in FIG. 4, in each subpixel group 260, the first and second central connecting lines between the center of the first color subpixel 210 and the centers of the two second color subpixels 220, and the third and fourth central connecting lines between the center of the third color subpixel 230 and the centers of the two second color subpixels 220 form a first virtual rectangle, and at least one interior angle of the first virtual rectangle is not equal to 90 degrees.

In this way, 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. For clarity, the symbol of the second virtual square is not shown in Fig. 4, and the symbol of the second virtual square may refer to Fig. 1A.

[0133] In some examples, as shown in FIG. 4, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal, thereby further ensuring the uniform distribution of each sub-pixel, thereby further improving the pixel density under the premise of fully utilizing the process precision.

[0134] In some examples, as shown in FIG. 4, a fifth distance D5 between the first straight side 312C of the third color subpixel 230 and the adjacent first color subpixel 210 may be greater than the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4, respectively.

[0135] 5A is a schematic plan view of another display substrate according to an embodiment of the present disclosure. As shown in FIG. 5A, the display substrate 100 includes a base substrate 110 and a plurality of sub-pixels 200, the sub-pixels 200 are located on the base substrate 110, and the orthogonal projection shape of at least one of the sub-pixels 200 on the base substrate 110 includes a first shape 310, the first shape 310 includes a first curved edge 311 and a second curved edge 312, and both 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.

[0136] The first shape 310 shown in Fig. 5A is the same as the first shape 310 shown in Fig. 1A, 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, in the same third color subpixel row, the distribution of third color subpixels having different arrangement orders is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and thus improving the display uniformity at different viewing angles.

[0138] In some examples, the first color subpixel 210 may be circular in shape and the second color subpixel 220 may be elliptical in shape, as shown in Figure 5A. Of course, the embodiments of the present disclosure include, but are not limited to, the first color subpixel and the second color subpixel may have other shapes.

[0157] In some examples, as shown in FIG. 5A, the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are all equal, thereby further ensuring the uniform distribution of each sub-pixel, thereby further improving the pixel density under the premise of fully utilizing the process precision.

[0158] 6A-6B are schematic plan views of another display substrate according to an embodiment of the present disclosure. As shown in Fig. 6A, the display substrate 100 includes a base substrate 110 and a plurality of sub-pixels 200, the sub-pixels 200 are located on the base substrate 110, and the orthogonal projection shape of at least one of the sub-pixels 200 on the base substrate 110 includes a first shape 310. For a detailed description of the first shape 310, please refer to the related description of Fig. 1A, and a detailed description will be omitted here.

[0159] As shown in FIG. 6A , the shape of at least one subpixel 200 when orthogonally projected on the base substrate 110 includes a second shape 320, the second shape 320 including a third curved side 321 and a fourth curved side 322, both ends of the third curved side 321 and both ends of the fourth curved side 322 are connected to form a third connection point P3 and a fourth connection point P4, and the length of the second connection line CL2 between the third connection point P3 and the fourth connection point P4 is equal to or longer than the extension length of the second connection line CL2 of the second shape 320. The maximum length in the direction, the second shape 320 is divided by the second connecting line CL2 into a third sub-portion 320A including the third curved side 321 and a fourth sub-portion 320B including the fourth curved side 322, the area of ​​the third sub-portion 320A is larger than the area of ​​the fourth sub-portion 320B, and the maximum vertical distance between each point on the third curved side 321 and the second connecting line CL2 is larger than the maximum vertical distance between each point on the fourth curved side 322 and the second connecting line CL2. Note that the maximum vertical distance between each point on the third curved side and the second connecting line refers to the longest of multiple vertical distances between each point on the third curved side and the second connecting line, while the maximum vertical distance between each point on the fourth curved side and the second connecting line refers to the longest of multiple vertical distances between each point on the fourth curved side and the second connecting line.

[0160] In the display substrate according to the embodiment of the present disclosure, the shape of at least one sub-pixel orthogonally projected on the base substrate includes a first shape, and the shape of at least one sub-pixel orthogonally projected on the base substrate includes a second shape, and the second shape includes a third curved edge and a fourth curved edge, so that the shape of at least one sub-pixel orthogonally projected on the base substrate is smoother, thereby reducing or even avoiding the occurrence of color separation. In addition, the second shape is divided by the second connecting line into a third sub-part including the third curved edge and a fourth sub-part including the fourth curved edge, and 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 larger than the maximum vertical distance between each point on the fourth curved edge and the second connecting line, so that the sub-pixel having the second shape can better avoid the occurrence of color separation. In addition, by providing the third curved edge and the fourth curved edge, 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. In addition, the display substrate may further form other functional components, such as spacers, fingerprint recognition units, photosensitive devices, etc., at a position of the fourth curved edge away from the third curved edge, so that other functions can be better integrated into the display substrate. In some examples, as shown in FIG. 6A, the curvature of the vertex of the third curved edge 321 away from the second connecting line CL2 is greater than the curvature of the vertex of the fourth curved edge 322 away from the second connecting line CL2.

[0161] In some examples, as shown in FIG. 6A, the third curved side 321 is a continuously curved side and the fourth curved side 322 is a continuously curved side.

[0162] In some examples, as shown in Figure 6A, the length of the second connection line CL2 is smaller than the length of the first connection line CL1, i.e., the second shape is similar to the first shape, but the dimensions of the second shape are smaller than the dimensions of the first shape.

[0163] In some examples, as shown in FIG. 6A , the plurality of subpixels 200 includes a first color subpixel 210, a second color subpixel 220, and a third color subpixel 230, where the first color subpixel 210 is configured to emit light of a first color, the second color subpixel 220 is configured to emit light of a second color, and the third color subpixel 230 is configured to emit light of a third color.

[0164] 6A , the area of ​​the third color subpixel 230 is larger than the area of ​​the first color subpixel 210, and the area of ​​the third color subpixel 230 is larger than the area of ​​the second color subpixel 210. By setting the area of ​​the subpixel with a relatively short emission lifetime to be larger, the service lifetime of the subpixel with a relatively short emission lifetime can be extended, thereby balancing the service lifetime of different subpixels.

[0165] For example, the first color may be red, the second color may be green, and the third color may be blue. Of course, the embodiments of the present disclosure include, but are not limited to, the first color, the second color, and the third color may be other colors.

[0166] In some examples, as shown in FIG. 6A , the shape of the orthogonal projection of the third color subpixel 230 on the base substrate 110 is a first shape 310, and a plurality of third color subpixels 230 are arranged in an array along the row direction and the column direction to form a third color subpixel row 237 extending along the row direction, and the plurality of third color subpixel rows 237 are sequentially arranged along the column direction, and the first curved side 311 and the second curved side 312 of the first shape 310 have an arrangement order in a direction perpendicular to the first connecting line CL1, and the same third color subpixels 230 are arranged in a row direction. In the first subpixel row 237, the arrangement order of two adjacent third color subpixels 230 is reversed, the extension direction of the first connection line CL1 of the first shape 310 of the third color subpixel 230 in one of the two adjacent third color subpixel rows 237 is parallel to the row direction, and the extension direction of the first connection line CL1 of the first shape 310 of the third color subpixel 230 in the other of the two adjacent third color subpixel rows 237 is parallel to the column direction. This allows the display substrate to distribute the third color subpixels having different arrangement orders relatively uniformly, thereby ensuring that the display effect displayed by the display substrate at different viewing angles is the same, thereby improving the display uniformity at different viewing angles. Note that the arrangement order of the first curved side and the second curved side of the third color subpixel may refer to the related description of FIG. 1A, and a detailed description thereof will be omitted here.

[0167] 6A , a plurality of first color subpixels 210 are arranged in an array along the row and column directions to form a first color subpixel row 217 extending along the row direction, the plurality of first color subpixel rows 217 are sequentially arranged 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 a direction perpendicular to the second connecting line CL2, and the arrangement order of two adjacent first color subpixels 210 in the same first color subpixel row 217 is reversed. For example, the first color subpixel row 217 and the third color subpixel row 237 may be the same subpixel row.

[0168] In the display substrate of this example, the arrangement orders of two adjacent first color subpixels in the same first color subpixel row are reversed, so that the distribution of first color subpixels with different arrangement orders in the same first color subpixel row is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, and thereby improving the display uniformity at different viewing angles.

[0169] 6A , the arrangement orders of the third curved edge 321 and the fourth curved edge 322 include a third order and a fourth order that are reverse to each other, and a difference between the number of first color subpixels 210 having the third order and the number of first color subpixels 210 having the fourth order in the same first color subpixel row 217 is less than 10. This ensures that the distribution of first color subpixels having different arrangement orders in the same first color subpixel row is relatively uniform, thereby ensuring that the display effects displayed by the display substrate at different viewing angles are the same, thereby improving the display uniformity at different viewing angles.

[0170] For example, in the same first color subpixel row 217, the difference between the number of first color subpixels 210 having the third order and the number of first color subpixels 210 having the fourth order is less than 2, thereby making the first color subpixels having different arrangement orders relatively uniform.

[0171] For example, as shown in FIG. 6A , in the same first color subpixel row 217, in the second shape 320 of one of two adjacent first color subpixels 210, the third curved side 321 and the fourth curved side 322 may be arranged sequentially along a direction from left to right in FIG. 6A , and in the second shape 320 of the other of the two adjacent first color subpixels 210, the third curved side 321 and the fourth curved side 322 may be arranged sequentially along a direction from right to left in FIG. 6A . Further, for example, as shown in FIG. 6A , in the same first color subpixel row 217, in the second shape 320 of one of two adjacent first color subpixels 210, the third curved side 321 and the fourth curved side 322 may be arranged sequentially along a top-to-bottom direction in FIG. 6A , and in the second shape 320 of the other of the two adjacent first color subpixels 210, the third curved side 321 and the fourth curved side 322 may be arranged sequentially along a bottom-to-top direction in FIG. 6A .

[0172] 6A , the extension direction of the second connecting lines CL2 of the second shapes 320 of the first color subpixels 210 in one of two adjacent first color subpixel rows 217 is parallel to the row direction, and the extension direction of the second connecting lines CL2 of the second shapes 320 of the first color subpixels 210 in the other of the two adjacent first color subpixel rows 217 is parallel to the column direction. Thus, the display substrate sets the extension directions of the first connecting lines of the third color subpixels in two adjacent third color subpixel rows to be parallel to the row direction and the column direction, respectively, so as to further ensure that the display effects displayed by the display substrate at different viewing angles are the same, and further improve the display uniformity at different viewing angles.

[0173] In some examples, as shown in FIG. 6B , the shape of the orthogonal projection of at least one subpixel 200 on the base substrate 110 includes a third shape 330, the third shape 330 including a fifth curved edge 331 and a sixth curved edge 332, both ends of the fifth curved edge 331 and both ends of the sixth curved edge 332 are connected to form a fifth connection point P5 and a sixth connection point P6, the length of the third connection line CL3 between the fifth connection point P5 and the sixth connection point P6 is the maximum length of the third shape 330 in the extension direction of the third connection line CL3, the third shape 330 is divided by the third connection line CL3 into a fifth sub-portion 330A including the fifth curved edge 331 and a sixth sub-portion 330B including the sixth curved edge 332, the area of ​​the fifth sub-portion 330A is equal to the area of ​​the sixth sub-portion 330B, and the fifth curved edge 331 and the sixth curved edge 332 are arranged axially symmetrically with respect to the third connection line CL3. Therefore, the shape of the orthogonal projection of the sub-pixel having the third shape on the base substrate is smoother, thereby reducing or even avoiding the occurrence of color separation. Note that the display substrate shown in Fig. 6B is the same as the display substrate shown in Fig. 6A, and other reference numerals are omitted in Fig. 6B to better illustrate the relevant features of the third color sub-pixel.

[0174] In some examples, the second color subpixels 220 may have an elliptical shape, as shown in Figure 6B. Of course, the embodiments of the present disclosure include, but are not limited to, the second color subpixels may have a circular shape.

[0175] In some examples, as shown in FIG. 6B, the fifth curved side 331 is a continuously curved side and the sixth curved side 332 is a continuously curved side.

[0176] In some examples, as shown in FIG. 6B, the length of the third connection line CL3 is smaller than the length of the first connection line CL1.

[0177] 6A and 6B , in some examples, when the plurality of subpixels 200 includes a first color subpixel 210, a second color subpixel 220, and a third color subpixel 230, the third color subpixel 230 has a first shape 310 when orthogonally projected on the base substrate 110, the first color subpixel 210 has a second shape 320 when orthogonally projected on the base substrate 110, and the second color subpixel 220 has a third shape 330 when orthogonally projected on the base substrate 110. This makes the shapes of the first color subpixel, the second color subpixel, and the third color subpixel smoother, thereby reducing or even avoiding the occurrence of the color separation phenomenon.

[0178] In some examples, as shown in Figures 6A and 6B, the length of the third connecting line CL3 is equal to the length of the second connecting line CL2, i.e., the length of the major axis of the ellipse of the second color subpixel 220 is equal to the length of the second connecting line CL2.

[0179] 6A and 6B , the plurality of subpixels 200 includes a plurality of subpixel groups 260, each of which includes one first color subpixel 210, two second color subpixels 220, and one third color subpixel 230, and in each subpixel group 260, the first color subpixel 210 and the third color subpixel 230 are arranged along a first direction X, and the two second color subpixels 220 are arranged along a second direction Y, and the central connecting lines of the first color subpixel 210 and the third color subpixel 230 intersect with the central connecting lines of the two second color subpixels 220. When the display substrate according to the example is used for display, the two second color subpixels 220 in one pixel group can respectively constitute two independent light-emitting pixel points together with the first color subpixel 210 and the third color subpixel 230, thereby realizing higher resolution through the principle of pixel borrowing.

[0180] In some examples, as shown in FIGS. 6A and 6B , a plurality of first color subpixels 210 and a plurality of third color subpixels 230 may be arranged in an alternating manner along a first direction X to form a first subpixel row 270, a plurality of second color subpixels 220 may be arranged in the first direction X to form a second subpixel row 280, and the plurality of first subpixel rows 270 and the plurality of second subpixel rows 280 may be arranged in an alternating manner along a second direction Y.

[0181] 6A and 6B, in the same second subpixel row 280, the major axes of the ellipses of two adjacent second-color subpixels 220 are axially symmetric, for example, axially symmetric with respect to the second direction Y. For example, the included angle between the extensions of the major axes of the ellipses of two adjacent second-color subpixels 220 in the same second subpixel row 280 is in the range of 80 to 100 degrees.

[0182] 6A and 6B , in two adjacent second subpixel rows 280, the major axes of the ellipses of two second-color subpixels 220 adjacent in the second direction Y are axially symmetric, e.g., axially symmetric with respect to the first direction X. For example, in the same second subpixel row 280, the included angle between the extensions of the major axes of the ellipses of two second-color subpixels 220 adjacent in the second direction Y is in the range of 80 to 100 degrees.

[0183] In some examples, as shown in Figures 6A and 6B, the display substrate 100 may be an array substrate for display, and the lamination relationship of the anode, pixel definition layer and light-emitting functional layer in the array substrate in the direction perpendicular to the base substrate may refer to the related description of Figure 2. Of course, the embodiments of the present disclosure include but are not limited to the above, and the display substrate may be a color film substrate, and refer to the related description of Figure 3.

[0184] 6A and 6B , in each subpixel group 260, the first and second central connecting lines between the center of the first color subpixel 210 and the centers of the two second color subpixels 220, and the third and fourth central connecting lines between the center of the third color subpixel 230 and the centers of the two second color subpixels 220 form a first virtual rectangle 480, and at least one interior angle of the first virtual rectangle 480 is not equal to 90 degrees. This allows the display substrate to better avoid the occurrence of color separation, and further allows the size and distance of different subpixels to be flexibly adjusted according to the luminous efficiency and color index of different color subpixels to achieve a better display effect.

[0185] For clarity, the reference numbers of each center connecting line are not shown in Figures 6A and 6B, and the reference numbers of the first center connecting line, the second center connecting line, the third center connecting line, and the fourth center connecting line may refer to Figure 1A.

[0186] 6A and 6B, in some examples, the value range of one interior angle of the first imaginary rectangle 480 is 84 to 94 degrees. For example, one interior angle of the imaginary rectangle may be 92 degrees.

[0187] In some examples, as shown in Figures 6A and 6B, the central connecting lines of two first color sub-pixels 210 and two third color sub-pixels 230 in two sub-pixel groups 260 adjacent to each other in the second direction Y may form a second virtual square 490, in which at least one interior angle of the second virtual square 490 is not equal to 90 degrees. This allows the display substrate to better avoid the occurrence of color separation phenomenon, and further allows the size and distance of different sub-pixels to be flexibly adjusted according to the luminous efficiency and color index of different color sub-pixels to achieve a better display effect. For clarity, the symbol of the second virtual square is not shown in Figures 6A and 6B, and the symbol of the second virtual square may refer to Figure 1A.

[0188] 6A and 6B, in each subpixel group 260, the first color subpixel 210 and the two second color subpixels 220 have a first distance D1 and a second distance D2, the third color subpixel 230 and the two second color subpixels 220 have a third distance D3 and a fourth distance D4, and at least two of the first distance D1, the second distance D2, the third distance D3, and the fourth distance D4 are equal, so that the display substrate can ensure a uniform distribution of each subpixel, thereby improving the pixel density under the premise of making full use of the process precision.

[0189] In some examples, as shown in Figures 6A and 6B, the first distance D1, the second distance D2, the third distance D3 and the fourth distance D4 are all equal, thereby further ensuring the uniform distribution of each sub-pixel, thereby further improving the pixel density under the premise of fully utilizing the process precision.
