Description

Display substrate and display device

[0001] This application claims priority to Chinese patent application No. 202311040476.3 filed on August 17, 2023. The contents of the above-mentioned Chinese patent application disclosure are hereby incorporated by reference in their entirety as a part of this application. Technical Field

[0002] Embodiments of the present disclosure relate to a display substrate and a display device. Background Art

[0003] As organic light-emitting diode (OLED) display substrates expand into diverse applications and product forms, demand for electronic products using them continues to increase. These products include smartphones, TVs, computers, tablets, navigation systems, in-car central control screens, and smartwatches.

[0004] On the other hand, in the production process of an organic light-emitting diode display substrate, an evaporation process is usually required to form the organic light-emitting layer in the organic light-emitting diode display substrate. The evaporation process requires a fine metal mask (FMM) to control the evaporation position of the organic light-emitting layer of each sub-pixel. A spacer is provided above the pixel definition layer (PDL) of the substrate to be evaporated. The spacer can not only support the fine metal mask during the evaporation process to prevent the fine metal mask from scratching the display substrate, but also can be used to maintain the distance between the fine metal mask and the display substrate to avoid electrostatic adsorption, thereby avoiding damage to the fine metal mask and increasing the rigidity of the display substrate.

[0067] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0068] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0069] As the application areas and product forms of organic light-emitting diode (OLED) display substrates diversify, the design of OLED display substrates has become more diverse and complex, requiring complex and varied shapes and structures. For example, for a wearable smartwatch, the OLED display substrate must not only display images on the top surface of the smartwatch, but also on the side or curved portion of the side. Therefore, the pixel arrangement structure of the OLED display substrate needs to be designed to cope with complex and varied shapes and structures to optimize the display effect.

[0070] On the other hand, spacers not only support the fine metal mask during the evaporation process, preventing it from scratching the display substrate, but also maintain the distance between the fine metal mask and the display substrate to prevent electrostatic adsorption, thereby preventing damage to the fine metal mask and increasing the rigidity of the display substrate. Therefore, given the complex and varied shapes and structures of display substrates, designing the position and size of spacers is a key issue in improving product yield and enhancing display quality.

[0071] To this end, an embodiment of the present disclosure provides a display substrate comprising a base substrate and a plurality of sub-pixels; the base substrate comprises a first display area, wherein the plurality of sub-pixels are located in the first display area; the plurality of first display areas comprise a first side and a second side arranged along a first direction, wherein the length of the first side is less than the length of the second side. The plurality of sub-pixels form a plurality of sub-pixel rows arranged along the first direction, wherein each sub-pixel row comprises N sub-pixels arranged along an extension direction of the first side or the second side; the plurality of sub-pixel rows are equidistantly arranged in the first direction, wherein a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and wherein the first distance of the plurality of sub-pixel rows increases as the distance from the first side increases. Thus, in the case where the first display area has an irregular shape, by arranging the plurality of sub-pixel rows equidistantly in the first direction, wherein a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and wherein the first distance of the plurality of sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the display effect.

[0072] The disclosed embodiment also provides another display substrate, which includes a base substrate and a plurality of spacers; the base substrate includes a first display area, and a plurality of spacers located in the first display area; the first display area includes a first side and a second side arranged along a first direction, the length of the first side being less than the length of the second side; the plurality of spacers form a plurality of spacer rows arranged along the first direction, each spacer row including K spacers arranged along the extension direction of the first side or the second side; the plurality of spacer rows are equidistantly arranged in the first direction, and a second distance exists between the centers of two adjacent spacers in each spacer row, and the second distance of the plurality of spacer rows increases as the distance from the first side increases. Thus, the display substrate can optimize the arrangement of the spacers, thereby preventing damage to the display substrate and the mask.

[0073] The present disclosure also provides a display device comprising the above-mentioned display substrate. Thus, the display device can have at least one of the following beneficial effects: (1) having a better display effect while having an irregular shape; (2) having a higher product yield; and (3) avoiding damage to the display substrate and the mask.

[0074] Hereinafter, the display substrate and the display device provided by the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0075] One embodiment of the present disclosure provides a display substrate. FIG1 is a partial plan view of a display substrate provided by one embodiment of the present disclosure. As shown in FIG1 , the display substrate 200 includes a base substrate 110 and a plurality of sub-pixels 210. The base substrate 110 includes a first display area 112, and the plurality of sub-pixels 210 are located in the first display area 112. The first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, wherein the length of the first side 112A is less than the length of the second side 112B. The plurality of sub-pixels 210 form a plurality of sub-pixel rows 220 arranged along the first direction. Each sub-pixel row 220 includes N sub-pixels 210 arranged along the extension direction of the first side 112A or the second side 112B. The plurality of sub-pixel rows 220 are equidistantly arranged in the first direction. The centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch, between them. The first distance in the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. That is, the pixel pitch of the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. It should be noted that because the length of the first side of the first display area is less than the length of the second side, the shape of the first display area is not a typical rectangle or square, but rather an irregular shape. Furthermore, the center of the sub-pixel may be a geometric center, which may have a certain error or range; for example, the geometric center of the sub-pixel may be within a radius of 3 μm centered at the geometric center of the sub-pixel.

[0076] In the display substrate provided in the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with display screens having complex shapes, thereby having a wide range of application scenarios. In addition, in the case where the first display area has an irregular shape, by arranging multiple sub-pixel rows equidistantly in the first direction, a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and the first distance of the multiple sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the pixel arrangement structure, thereby optimizing the display effect. On the other hand, the pixel arrangement of the display substrate is more regular, which is convenient for driving.

[0077] In some examples, as shown in FIG1 , the first display area 112 is a fan-shaped fan-shaped display area 112. In this case, the first side 112A is a first curved side, the second side 112B is a second curved side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along an arc direction. It should be noted that the arc direction can be the extension direction of the first curved side or the second curved side; in addition, the fan-shaped fan-shaped fan can be formed by removing the sharp corners.

[0078] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0079] In some examples, as shown in FIG. 1 , the base substrate 110 further includes a non-display area 118 located on a side of the first side 112A of the first display area 112 away from the second side 112B.

[0080] In some examples, the base substrate 110 located in the fan-ring display area 112 can be curved along a first direction. This allows the display substrate to achieve a curved display. Furthermore, because the base substrate in the fan-ring display area can be curved along the first direction, the pixel distribution and brightness of the display substrate are visually more uniform. Furthermore, when the base substrate in the fan-ring display area is curved along the first direction, the display substrate can form a display screen with more complex and diverse shapes.

[0081] In some examples, as shown in FIG1 , the plurality of sub-pixels 210 include a plurality of sub-pixel columns 230 arranged along an arc direction. Each sub-pixel column 230 includes M sub-pixels 210 arranged along a direction intersecting the arc direction. The extension directions of two sub-pixel columns 230 intersect at an intersection point, which is located on the side of the first arc-shaped edge 112A away from the second arc-shaped edge 112B. This makes the distribution of sub-pixels in the first display area more uniform, thereby improving display quality.

[0082] In some examples, as shown in FIG1 , first arcuate edge 112A has a first imaginary center, second arcuate edge 112B has a second imaginary center, and the first and second imaginary centers coincide with each other. The extension directions of any two sub-pixel columns 230 intersect at either the first or second imaginary centers. This arrangement allows the display substrate to achieve a more uniform distribution of sub-pixel columns, thereby improving display quality.

[0083] In some examples, as shown in Figure 1 , the centers of the N sub-pixels 210 in each sub-pixel row 220 may be located on a virtual arc centered on the first virtual center or the second virtual center.

[0084] In some examples, as shown in FIG. 1 , in each sub-pixel column 230 , the centers of the M sub-pixels 210 are arranged equidistantly, which can further improve the uniformity of pixel distribution and thus enhance display quality.

[0085] In some examples, as shown in FIG1 , sub-pixels 210 may include three types of sub-pixels, namely, a first sub-pixel 211, a second sub-pixel 212, and a third sub-pixel 213; the first sub-pixel 211 is configured to emit light of a first color, the second sub-pixel 212 is configured to emit light of a second color, and the third sub-pixel 213 is configured to emit light of a third color. It should be noted that the shape of each sub-pixel shown in FIG1 may be the shape of the emission region or light-emitting region of each sub-pixel, which may generally be defined by a pixel opening in a pixel-defining layer.

[0086] For example, the first color is green, the second color is blue, and the third color is red. Of course, the embodiments of the present disclosure include but are not limited to the above.

[0087] 1 , the number of first sub-pixels 211 is twice the number of second sub-pixels 212 or third sub-pixels 213. Thus, the display substrate can improve the resolution (PPI) by using a pixel borrowing algorithm.

[0088] In some examples, as shown in FIG1 , the plurality of sub-pixel rows 220 include a plurality of alternating first sub-pixel rows 220A and second sub-pixel rows 220B. Each first sub-pixel row 220A includes a plurality of first sub-pixels 211 arranged along an arc, and each second sub-pixel row 220B includes a plurality of second sub-pixels 212 and a plurality of third sub-pixels 213 arranged along an arc. In each second sub-pixel row 220B, the plurality of second sub-pixels 212 and the plurality of third sub-pixels 213 are arranged alternately. Thus, the display substrate facilitates pixel borrowing, fully utilizes process precision, and improves deposition stability.

[0089] In some examples, as shown in FIG1 , the areas of the plurality of first sub-pixels 211 in the first pixel row 220A are approximately equal, the areas of the plurality of second sub-pixels 212 in the second sub-pixel row 220B are approximately equal, and the areas of the plurality of third sub-pixels 213 in the second sub-pixel row 220B are approximately equal.

[0090] In some examples, as shown in FIG1 , the area of ​​the second sub-pixel 212 is larger than the area of ​​the third sub-pixel 213, and the area of ​​the third sub-pixel 213 is larger than the area of ​​the first sub-pixel 211. Thus, the display substrate can balance the service life of various sub-pixels. Of course, the embodiments of the present disclosure include but are not limited to this. As the service life of different color luminescent materials changes, the area of ​​different sub-pixels can be set according to actual conditions.

[0091] In some examples, as shown in FIG1 , the distance between any two adjacent first sub-pixels 211 in each first sub-pixel row 220A is equal, and the distance between any two adjacent third sub-pixels 213 in each second sub-pixel column 220B is equal. Thus, the display substrate can improve the uniformity of pixel distribution.

[0092] In some examples, as shown in FIG1 , the first sub-pixels 211 are shaped like elongated strips extending in a direction. In each first pixel row 220A, the extending directions of two adjacent first sub-pixels 211 intersect. This allows the display substrate to achieve a more compact pixel arrangement, improve display quality, and prevent artifacts such as vertical lines.

[0093] In some examples, as shown in FIG. 1 , in each first pixel row 220A, the extension directions of two adjacent first sub-pixels 211 are perpendicular to each other.

[0094] In some examples, as shown in FIG1 , the shape of the second sub-pixel 212 includes an arcuate edge 2121 and a right-angled edge 2122 that are arranged in opposite directions. In each second pixel row 220B, the arcuate edges 2121 and the right-angled edges 2122 of two adjacent second sub-pixels 212 are arranged in a different order, for example, in the opposite order. Thus, by making the arcuate edges smoother, this pixel arrangement structure can reduce or even prevent the occurrence of color separation. Furthermore, by providing second sub-pixels with the aforementioned arcuate edges and right-angled edges, this pixel arrangement structure can flexibly adjust the size and distance between different sub-pixels to achieve a better display effect.

[0095] In some examples, as shown in FIG1 , the shape of the second sub-pixel 212 includes a first corner 212A and a second corner 212B that are arranged opposite each other, wherein the distance between the vertex of the first corner 212A and the geometric center of the second sub-pixel 212 is greater than the distance between the vertex of the second corner 212B and the geometric center of the second sub-pixel 212; in each second pixel row 220B, the arrangement order of the first corner 212A and the second corner 212B of two adjacent second sub-pixels 212 is opposite. In other words, the shape of the second sub-pixel 212 is not axisymmetric. Thus, this pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the edges of the second corners smoother. Furthermore, this pixel arrangement structure can flexibly adjust the size and distance between different sub-pixels to achieve a better display effect by providing second sub-pixels with the above-mentioned first and second corners. It should be noted that the above-mentioned color indicators can be parameters such as brightness, color gamut, color temperature, and wavelength of the light emitted by the sub-pixels.

[0096] In other examples, the second sub-pixel may be circular, thereby effectively improving the color separation phenomenon under optical diffraction and optimizing the display effect. Simultaneously, the first and third sub-pixels may also be circular, further improving the color separation phenomenon under optical diffraction and optimizing the display effect. Of course, the shapes of the sub-pixels in the embodiments of the present disclosure include but are not limited to those described above, and the shapes of the sub-pixels may be polygonal, elliptical, or other shapes.

[0097] For example, as shown in FIG. 1 , the right-angled side 2122 may be the side of the first corner 212A away from the geometric center of the second sub-pixel 212 , and the arcuate side 2121 may be the side of the second corner 212B away from the geometric center of the second sub-pixel 212 .

[0098] In some examples, as shown in FIG1 , the plurality of sub-pixels 210 include a plurality of first sub-pixel columns 230A and a plurality of second sub-pixel columns 230B arranged alternately along an arc direction, that is, the sub-pixel columns 230 include first sub-pixel columns 230A and second sub-pixel columns 230B; each first sub-pixel column 230A includes a plurality of first sub-pixels 211 arranged along a first direction, and each second sub-pixel column 230B includes a plurality of second sub-pixels 212 and a plurality of third sub-pixels 213 arranged along the first direction.

[0099] In some examples, as shown in FIG1 , the first sub-pixels 211 are shaped like elongated strips extending in a direction. In each first pixel column 230A, the extending directions of two adjacent first sub-pixels 211 intersect. This allows the display substrate to achieve a more compact pixel arrangement, improve display quality, and prevent artifacts such as vertical lines.

[0100] For example, as shown in Figure 1, the shape of the first sub-pixel 211 can be a rounded rectangle, and the shape of the third sub-pixel 213 can be any one of a square, a rectangle, and a diamond. Of course, the embodiments of the present disclosure include but are not limited to this.

[0101] In some examples, as shown in FIG1 , the shape of the second sub-pixel 212 includes an arcuate edge 2121 and a right-angled edge 2122 arranged opposite each other. In each second pixel column 230B, the arcuate edges 2121 and the right-angled edges 2122 of two adjacent second sub-pixels 212 are arranged in a different order, for example, in the opposite order. Thus, by making the arcuate edges smoother, this pixel arrangement structure can reduce or even prevent the occurrence of color separation. Furthermore, by providing second sub-pixels with the aforementioned arcuate edges and right-angled edges, this pixel arrangement structure can flexibly adjust the size and distance between different sub-pixels to achieve a better display effect.

[0102] In some examples, as shown in FIG1 , the display substrate 200 further includes a plurality of spacers 120 located in the fan-ring display area 112; the plurality of spacers 120 form a plurality of spacer columns 130 arranged along an arc direction, and each spacer column 130 includes a plurality of spacers 120 arranged along a direction intersecting the arc direction; in each spacer column 130, the centers of the plurality of spacers 120 are arranged equidistantly, and the extension directions of any two spacer columns 130 intersect at a position where the first arc-shaped edge 112A is away from the second arc-shaped edge 112B. Thus, the display substrate also designs the position of the spacers so that the distribution of the spacers is more reasonable, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate and mask plate to be evaporated. It should be noted that the center of the above-mentioned spacer can be a geometric center, and the geometric center can allow a certain error or range.

[0103] In some examples, as shown in FIG1 , in each spacer column 130 , the size of the spacer 120 along the arc increases as the distance from the first curved edge 112A increases. As a result, the display substrate can maintain a consistent area ratio of the spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate. Furthermore, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned arrangement to avoid electrostatic adsorption, thereby preventing damage to the delicate metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0104] In some examples, as shown in FIG1 , each spacer 120 includes a first spacer edge 120A proximate to the first arcuate edge 112A and a second spacer edge 120B proximate to the second arcuate edge 112B, with the first spacer edge 120A and the second spacer edge 120B being disposed opposite each other. In each spacer row 130, the first spacer edge 120A of the spacer 120 increases in size as the distance from the first arcuate edge 112A increases, and in each spacer row 130, the second spacer edge 120B of the spacer 120 increases in size as the distance from the first arcuate edge 112A increases. Thus, the size or area of ​​the spacers is increased by increasing the sizes of the first spacer edge and the second spacer edge, respectively.

[0105] In some examples, as shown in Figure 1, for a spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. This arrangement further maintains a consistent area ratio of spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0106] In some examples, as shown in FIG1 , the spacers 120 may be first spacers 121, each first spacer 121 being located between two adjacent first sub-pixels 211. The plurality of first spacers 121 form a plurality of first spacer columns 131 arranged along an arc direction, each first spacer column 131 including a plurality of first spacers 121 arranged along a direction intersecting the arc direction. Within each first spacer column 131, the centers of the plurality of first spacers 121 are equidistantly arranged, and the extension directions of any two first spacer columns 131 intersect at a position where the first arcuate edge 112A is spaced away from the second arcuate edge 112B. Thus, the display substrate further designs the spacer positions to achieve a more reasonable distribution of the spacers, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0107] In some examples, as shown in FIG1 , in each first spacer column 131 , the size of the first spacer 121 in the arc direction increases as the distance from the first curved edge 112A increases. Thus, the display substrate can maintain a consistent area ratio of the first spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate. Furthermore, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned arrangement to avoid electrostatic adsorption, thereby avoiding damage to the delicate metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0108] Figure 2 compares spacers in the first display area of ​​a display substrate provided in one embodiment of the present disclosure with spacers in other display areas. As shown in Figure 2, within each spacer column 130 in the first display area 112, the centers of the multiple spacers 120 are equidistantly spaced, and the size of the spacers 120 along the arc increases with increasing distance from the first curved edge 112A. In other display areas (such as the second display area described below), the spacer size remains constant.

[0109] In some examples, as shown in FIG2 , each spacer 120 includes a first spacer edge 120A and a second spacer edge 120B disposed opposite each other. The first spacer edge 120A of the spacer 120 gradually increases in size within each spacer row 130, and the second spacer edge 120B of the spacer 120 gradually increases in size within each spacer row 130. Thus, the size or area of ​​the spacers is increased by increasing the size of the first spacer edge and the second spacer edge, respectively.

[0110] In some examples, as shown in Figure 2, for a spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. This arrangement further maintains a consistent area ratio of spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0111] Figure 3 is a schematic cross-sectional view of a display substrate provided by one embodiment of the present disclosure. Figure 3 is a schematic cross-sectional view taken along the extending direction of the spacer array in Figure 1 . As shown in Figure 3 , the display substrate 200 further includes a pixel driving circuit 150, a first electrode 160, a pixel defining layer 170, and a light-emitting functional layer 180 located on a base substrate 110. The pixel driving circuit 150 is disposed on the base substrate 110 and may include components such as thin-film transistors and capacitors. The first electrode 160 is connected to the output terminal of the pixel driving circuit 150, thereby receiving the current or voltage output by the pixel driving circuit 150. The pixel defining layer 170 is disposed on a side of the first electrode 160 away from the base substrate 110 and may include a plurality of pixel openings 175. The light-emitting functional layer 180 is formed within the pixel openings 175 of the pixel defining layer 170 and contacts the first electrode 160 through the pixel openings 175. The portion or region of the light-emitting functional layer 180 that contacts the first electrode 160 through the pixel openings 175 can emit light under electrical drive from the first electrode 160. Therefore, the shape of each sub-pixel in the embodiment of the present disclosure may be the shape of the emission area or the light-emitting area of ​​each sub-pixel, and the light-emitting area may generally be defined by the pixel opening in the pixel-defining layer, or by the portion or area of ​​the light-emitting functional layer that contacts the first electrode through the pixel opening. It should be noted that a typical display substrate may further include a second electrode (not shown) located on the light-emitting functional layer, and the light-emitting functional layer emits light under the drive of the first electrode and the second electrode.

[0112] In some examples, as shown in FIG3 , the display substrate 200 further includes spacers 120 located between the pixel openings 175 on the pixel defining layer 170. In the same spacer column 130, the geometric centers of the spacers 120 are equidistantly arranged, and the dimensions of the spacers 120 along the extending direction of the spacer column 130 remain constant.

[0113] In some examples, as shown in FIG. 3 , the display substrate 200 further includes a buffer layer 142 on the base substrate 110 . The buffer layer 142 can modify defects on the base substrate 110 , thereby improving the quality of subsequent scratches.

[0114] In some examples, as shown in FIG. 3, the display substrate 200 further includes a planar layer 145 on a side of the pixel driving circuit 150 away from the substrate 110. The first electrode 160 is disposed on a side of the planar layer 145 away from the substrate 110 and is connected to the pixel driving circuit 150 through a via hole in the planar layer 145.

[0115] FIG. 4 is a partial plan schematic diagram of a display substrate provided by an embodiment of the present disclosure. FIG. 4 only shows the arrangement of the first sub-pixels. As shown in FIG. 4, in the first sub-pixel row 220A composed of multiple first sub-pixels 211, the geometric centers of the multiple first sub-pixels 211 can be located on the same circular arc. In the first sub-pixel column 230A composed of multiple first sub-pixels 211, the geometric centers of the multiple first sub-pixels 211 are arranged at equal distances.

[0116] In some examples, as shown in FIG. 4, multiple first sub-pixel rows 220A are sequentially distributed on concentric circular arcs with radii of R1, R2, R3, and R4; in the radial direction of these circular arcs, the distance between the geometric centers of any two adjacent first sub-pixels 211 is equal, that is, PR1 = PR2 = PR3; in the extending direction of these circular arcs, the distance between the geometric centers of adjacent first sub-pixels 211 in the same first sub-pixel row 220A is equal. In different multiple first sub-pixel rows 220A, the distance between the geometric centers of adjacent first sub-pixels 211 in the extending direction of the circular arc increases as the radius of the circular arc increases, that is, Pθ1 < Pθ2 < Pθ3 < Pθ4, where θ is the included angle between the extending directions of adjacent first sub-pixel columns.

[0117] It should be noted that the above content takes the first sub-pixel in FIG. 4 as an example to illustrate the arrangement of the sub-pixels. The arrangements of the second sub-pixel and the third sub-pixel can be the same as or similar to that of the first sub-pixel.

[0118] FIG. 5 is a schematic diagram of a display substrate provided by an embodiment of the present disclosure. As shown in FIG. 5, the substrate 110 further includes a second display area 114, and the shape of the second display area 114 can be rectangular; the second display area 114 is located on one side of the first display area 112 along the extending direction of the first side 112A or the second side 112B. Thus, the display substrate can form an annular display area through the first display area and the second display area, so that the display device using the display substrate has a better display effect.

[0119] For example, as shown in FIG. 5, the display substrate can form an annular display area through four first display areas 112 and four second display areas 114 and can be applied to the border of the display device, so that the border of the display device can also display content.

[0120] It should be noted that the base substrate of the display substrate including multiple display areas may be continuous or spliced, and the embodiment of the present disclosure does not limit this.

[0121] FIG6 is a schematic diagram of another display substrate provided in accordance with an embodiment of the present disclosure. As shown in FIG6 , the fan-shaped ring shape in accordance with the present disclosure includes a fan-shaped ring shape in which the angle between the two straight sides is less than 180 degrees, and also includes a fan-shaped ring shape in which the angle between the two straight sides is greater than 180 degrees, as shown in FIG6 . In this case, the shape of the first display area 112 can be a circular ring shape including a notch. In addition, the fan-shaped ring shape provided in accordance with the present disclosure also includes a circular ring shape in which the angle between the two straight sides of the fan-shaped ring shape is 360 degrees.

[0122] An embodiment of the present disclosure further provides a display device. FIG7 is a schematic diagram of a display device provided by an embodiment of the present disclosure. As shown in FIG7 , the display device 500 includes the display substrate 200 described above. Thus, the display device can have at least one of the following beneficial effects: (1) having a better display effect while having an irregular shape; (2) having a higher product yield; and (3) avoiding damage to the display substrate and mask.

[0123] In some examples, as shown in FIG7 , the display device 500 includes a first display screen 510 and a second display screen 520; the second display screen 520 is disposed around the first display screen 510; and the second display screen 520 includes the aforementioned display substrate 200, that is, the second display screen 520 utilizes the aforementioned display substrate 200. Thus, the second display screen of the display device allows the frame of the display device to be displayed, thereby greatly improving the display effect.

[0124] In some examples, as shown in FIG. 7 , the second display screen 520 may be formed into a rectangular ring-shaped display area through four first display areas 112 and four second display areas 114 .

[0125] In some examples, as shown in FIG7 , the first display screen 510 includes a third display area 512 and a non-display area 514 surrounding the third display area 512 , and the second display screen 520 includes a first display area 112 of the display substrate 200 and a non-display area 118 located on the first side 112A away from the second side 112B. The non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520 are connected, thereby improving space utilization.

[0126] In some examples, as shown in FIG7 , the display device 500 further includes an annular cover plate 530 that covers the non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520. The annular cover plate protects the non-display areas to prevent light leakage and other defects. Furthermore, the annular cover plate can improve the appearance of the display device while enhancing product stability.

[0127] In some examples, as shown in FIG7 , the first display screen 510 includes a back surface and a light-emitting surface opposite the back surface. The second display screen 520 is curved from a first plane where the light-emitting surface is located to a second plane where the back surface is located. The first side 112A of the first display area 112 of the second display screen 520 is located in the first plane or closer to the first plane than the second side 112B. Thus, by curving the second display screen, the display device can fully cover the frame of the display device and further improve the display effect.

[0128] For example, the display device may be a smartwatch. Of course, the embodiments of the present disclosure include but are not limited to this, and the display device may also be any electronic product with a display function, such as a mobile phone, a computer, a navigation system, a car display, an electronic picture frame, a tablet computer, etc.

[0129] FIG8 is a schematic diagram of another display device provided by an embodiment of the present disclosure. As shown in FIG8 , the display device 500 includes the display substrate 200 described above. Thus, the display device can have at least one of the following beneficial effects: (1) having an irregular shape while having a better display effect; (2) having a higher product yield; and (3) avoiding damage to the display substrate and mask.

[0130] In some examples, as shown in FIG8 , the display device 500 includes a first display screen 510 and a second display screen 520; the second display screen 520 surrounds the periphery of the first display screen 510; and the second display screen 520 includes the aforementioned display substrate 200, that is, the second display screen 520 uses the aforementioned display substrate 200. Thus, the second display screen of the display device allows the frame of the display device to be displayed, thereby greatly improving the display effect.

[0131] In some examples, as shown in FIG8 , the first display area 112 of the display substrate 200 used by the second display screen 520 may be a circular display area, or multiple first display areas 112 of the display substrate 200 used by the second display screen 520 may be connected end to end to form a circular display area.

[0132] In some examples, as shown in FIG8 , the first display screen 510 includes a third display area 512 and a non-display area 514 surrounding the third display area 512 , and the second display screen 520 includes a first display area 112 of the display substrate 200 and a non-display area 118 located on the first side 112A away from the second side 112B. The non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520 are connected, thereby improving space utilization.

[0133] In some examples, as shown in FIG8 , the display device 500 further includes an annular cover plate 530 that covers the non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520. The annular cover plate protects the non-display areas to prevent light leakage and other defects. Furthermore, the annular cover plate can improve the appearance of the display device while enhancing product stability.

[0134] In some examples, as shown in FIG8 , the first display screen 510 includes a back surface and a light-emitting surface opposite the back surface. The second display screen 520 is curved from a first plane where the light-emitting surface is located to a second plane where the back surface is located. The first side 112A of the first display area 112 of the second display screen 520 is located in the first plane or closer to the first plane than the second side 112B. Thus, by curving the second display screen, the display device can fully cover the frame of the display device and further improve the display effect.

[0135] For example, the display device may be a smartwatch. Of course, the embodiments of the present disclosure include but are not limited to this, and the display device may also be any electronic product with a display function, such as a mobile phone, a computer, a navigation system, a car display, an electronic picture frame, a tablet computer, etc.

[0136] An embodiment of the present disclosure also provides another display substrate. FIG9 is a partial planar schematic diagram of another display substrate provided by an embodiment of the present disclosure; FIG10 is a partial planar schematic diagram of another display substrate provided by an embodiment of the present disclosure. It is worth noting that the pixel arrangement structure and spacer arrangement structure in the first display area of ​​the display substrate described below can be used to replace the pixel arrangement structure and spacer arrangement structure in the first display area of ​​the display substrate shown in any one of FIG1 to FIG6, and applied to the display device shown in FIG7 and FIG8.

[0137] As shown in Figure 9, Figure 9 shows the sub-pixel arrangement structure in the regular display area. In the regular display area, the multiple sub-pixels 210 may include multiple pixel groups 250; each pixel group 250 includes a first sub-pixel 211, a second sub-pixel 212 and a third sub-pixel 213; in each pixel group 250, the third sub-pixel 213 and the first sub-pixel 211 are arranged along a first direction and form a pixel pair, and the pixel pair and the second sub-pixel 212 are arranged along a second direction intersecting with the first direction.

[0138] As shown in Figure 10, the display substrate 200 includes a base substrate 110 and a plurality of sub-pixels 210; the base substrate 110 includes a first display area 112, and the plurality of sub-pixels 210 are located in the first display area 112; the first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, and the length of the first side 112A is less than the length of the second side 112B. The plurality of sub-pixels 210 form a plurality of sub-pixel rows 220 arranged along a first direction. Each sub-pixel row 220 includes N sub-pixels 210 arranged along the extending direction of the first side 112A or the second side 112B. The N sub-pixels 210 included in each sub-pixel row 220 form a plurality of pixel groups 250. Each pixel group 250 includes a first sub-pixel 211, a second sub-pixel 212, and a third sub-pixel 213. The plurality of sub-pixel rows 220 are equidistantly arranged in the first direction. A first distance, i.e., a pixel pitch, is defined between the centers of two adjacent sub-pixels 210 in each sub-pixel row 220. The first distance in the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. In other words, the pixel pitch of the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases.

[0139] It should be noted that, unlike the display substrate shown in Figure 1, the above-mentioned sub-pixel rows are rows formed by pixel groups 250; the first distance between the centers of two adjacent sub-pixels 210 in each of the above-mentioned sub-pixel rows 220 may be the distance between the two first sub-pixels 211 in two adjacent pixel groups 250, or the distance between the two second sub-pixels in two adjacent pixel groups 250, or the distance between the two third sub-pixels in two adjacent pixel groups.

[0140] In the display substrate provided in the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with display screens having complex shapes, thereby having a wide range of application scenarios. In addition, in the case where the first display area has an irregular shape, by arranging multiple sub-pixel rows equidistantly in the first direction, a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and the first distance of the multiple sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the pixel arrangement structure, thereby optimizing the display effect. On the other hand, the pixel arrangement of the display substrate is more regular, which is convenient for driving.

[0141] In some examples, as shown in FIG10 , the first display area 112 is a fan-shaped fan-shaped display area 112. In this case, the first side 112A is a first curved side, the second side 112B is a second curved side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along an arc direction. It should be noted that the arc direction can be the extension direction of the first curved side or the second curved side; in addition, the fan-shaped fan shape can be a fan-shaped fan with the acute angle portion removed.

[0142] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0143] In some examples, as shown in FIG. 10 , the base substrate 110 further includes a non-display area 118 located on a side of the first side 112A of the first display area 112 away from the second side 112B.

[0144] In some examples, the base substrate 110 located in the fan-ring display area 112 can be curved along a first direction. This allows the display substrate to achieve a curved display. Furthermore, because the base substrate in the fan-ring display area can be curved along the first direction, the pixel distribution and brightness of the display substrate are visually more uniform. Furthermore, when the base substrate in the fan-ring display area is curved along the first direction, the display substrate can form a display screen with more complex and diverse shapes.

[0145] In some examples, as shown in FIG. 10 , in each pixel group 250 , the third sub-pixel 213 and the first sub-pixel 211 are arranged along a first direction and form a pixel pair, and the pixel pair and the second sub-pixel 212 are arranged along an arc direction.

[0146] In some examples, as shown in FIG10 , the display substrate 200 includes a plurality of second spacers 122 ; each second spacer 122 is located between a pixel pair and a second sub-pixel 212 ; the plurality of second spacers 122 form a plurality of second spacer columns 132 arranged along an arc direction, each second spacer column 132 including a plurality of second spacers 122 arranged along a direction intersecting the arc direction; within each second spacer column 132 , the centers of the plurality of second spacers 122 are equidistantly arranged, and the extension directions of any two second spacer columns 132 intersect at a position where the first arcuate edge 112A is away from the second arcuate edge 112B. Thus, the display substrate also designs the spacer positions so that the spacer distribution is more reasonable, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0147] In some examples, as shown in FIG10 , in each second spacer column 132, the size of the second spacers 122 along the arc increases as the distance from the first arcuate edge 112A increases. Thus, the display substrate can maintain a consistent area ratio of the second spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0148] In some examples, as shown in FIG10 , the display substrate 200 further includes a plurality of third spacers 123 , each of which is located between two adjacent second sub-pixels 212 in the first direction. The plurality of third spacers 123 form a plurality of third spacer columns 133 arranged along an arc direction, each of which includes a plurality of third spacers 123 arranged along a direction intersecting the arc direction. Within each third spacer column 133 , the centers of the plurality of third spacers 123 are equidistantly arranged, and the extending directions of any two third spacer columns 133 intersect at a position where the first arcuate edge 112A is spaced away from the second arcuate edge 112B. Thus, the display substrate utilizes the gap between two adjacent second sub-pixels in the first direction to increase the number of spacers, thereby further effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0149] In some examples, as shown in FIG10 , in each third spacer column 133, the size of the third spacers 123 along the arc increases as the distance from the first arcuate edge 112A increases. Thus, the display substrate can maintain a consistent area ratio of the third spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0150] 10 , the dimension of the third spacer 123 along the arc direction is larger than the dimension of the third spacer 123 along the extension direction of the third spacer column 133. Thus, the third spacer can fully utilize space and improve resolution.

[0151] In some examples, as shown in FIG10 , the first sub-pixel 211 is configured to emit light of a first color, the second sub-pixel 212 is configured to emit light of a second color, and the third sub-pixel 213 is configured to emit light of a third color. It should be noted that the shape of each sub-pixel shown in the embodiments of the present disclosure may be the shape of the emission region or light-emitting region of each sub-pixel, which may generally be defined by a pixel opening in a pixel-defining layer.

[0152] For example, the first color is green, the second color is blue, and the third color is red. Of course, the embodiments of the present disclosure include but are not limited to the above.

[0153] In some examples, as shown in FIG10 , the area of ​​the second sub-pixel 212 is larger than the area of ​​the third sub-pixel 213 and the area of ​​the first sub-pixel 211. Thus, the display substrate can balance the service life of various sub-pixels. Of course, the embodiments of the present disclosure include but are not limited to this. As the service life of different color luminescent materials changes, the area of ​​different sub-pixels can be set according to actual conditions.

[0154] In some examples, as shown in FIG. 10 , the shapes of the first sub-pixel 211 , the second sub-pixel 212 , and the third sub-pixel 213 may be rectangular.

[0155] In other examples, at least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 in FIG10 can be replaced with a circle, thereby effectively improving the color separation phenomenon under optical diffraction and optimizing the display effect. Of course, the shape of each sub-pixel in the embodiments of the present disclosure includes but is not limited to the ones described above, and the shape of each sub-pixel can be other shapes such as polygonal and elliptical.

[0156] In some examples, as shown in FIG. 10 , the number of first sub-pixels 211 , the number of second sub-pixels 212 , and the number of third sub-pixels 213 are the same.

[0157] Figure 11 is a partial plan view of another display substrate provided in accordance with an embodiment of the present disclosure. As shown in Figure 11 , the display substrate 200 includes a base substrate 110 and a plurality of sub-pixels 210. The base substrate 110 includes a first display area 112, and the plurality of sub-pixels 210 are located in the first display area 112. The first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, with the first side 112A being shorter than the second side 112B. The plurality of sub-pixels 210 form a plurality of sub-pixel rows 220 arranged along a first direction. Each sub-pixel row 220 includes N sub-pixels 210 arranged along the extending direction of the first side 112A or the second side 112B. The N sub-pixels 210 included in each sub-pixel row 220 form a plurality of pixel groups 250. Each pixel group 250 includes a first sub-pixel 211, a second sub-pixel 212, and a third sub-pixel 213. The plurality of sub-pixel rows 220 are equidistantly arranged in the first direction. A first distance, i.e., a pixel pitch, is defined between the centers of two adjacent sub-pixels 210 in each sub-pixel row 220. The first distance in the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. In other words, the pixel pitch of the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. It should be noted that the first distance between the centers of two adjacent sub-pixels 210 in each of the above-mentioned sub-pixel rows 220 may be the distance between the two first sub-pixels 211 in two adjacent pixel groups 250, or the distance between the two second sub-pixels in two adjacent pixel groups 250, or the distance between the two third sub-pixels in two adjacent pixel groups.

[0158] In the display substrate provided in the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with display screens having complex shapes, thereby having a wide range of application scenarios. In addition, in the case where the first display area has an irregular shape, by arranging multiple sub-pixel rows equidistantly in the first direction, a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and the first distance of the multiple sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the pixel arrangement structure, thereby optimizing the display effect. On the other hand, the pixel arrangement of the display substrate is more regular, which is convenient for driving.

[0159] In some examples, as shown in FIG11 , the first display area 112 is a fan-shaped fan-shaped display area 112. In this case, the first side 112A is a first curved side, the second side 112B is a second curved side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along an arc direction. It should be noted that the arc direction can be the extension direction of the first curved side or the second curved side; furthermore, the fan-shaped fan-shaped fan can be formed by removing the sharp corners.

[0160] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0161] In some examples, as shown in FIG. 11 , the base substrate 110 further includes a non-display area 118 located on a side of the first side 112A of the first display area 112 away from the second side 112B.

[0162] In some examples, as shown in FIG11 , unlike the display substrate shown in FIG10 , the display substrate 200 does not include the second and third spacers. The display substrate 200 includes a plurality of fourth spacers 124 , each located between two adjacent pixel groups 250 . The plurality of fourth spacers 124 form a plurality of fourth spacer columns 134 arranged along an arc direction, each fourth spacer column 134 including a plurality of fourth spacers 124 arranged in a direction intersecting the arc direction. Within each fourth spacer column 134 , the centers of the plurality of fourth spacers 124 are equidistantly spaced, and the extension directions of any two fourth spacer columns 134 intersect at a location where the first arcuate edge 112A is spaced away from the second arcuate edge 112B. Therefore, the display substrate does not set spacers in the pixel group, which can avoid the adverse effects of the spacers on the color mixing of the sub-pixels in the pixel group, and can also prevent defects such as color deviation; on the other hand, the display substrate sets a fourth spacer between the pixel groups, which can effectively support and protect the mask plate and prevent damage to the substrate to be evaporated and the mask plate.

[0163] In some examples, as shown in FIG11 , in each fourth spacer column 134, the size of the fourth spacers 124 along the arc increases as the distance from the first arcuate edge 112A increases. Thus, the display substrate can maintain a consistent area ratio of the fourth spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0164] In some examples, as shown in Figure 11, the shape of the fourth spacer 124 can be an isosceles trapezoid. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the fourth spacer 124 can also be any other shape.

[0165] Figure 12 is a partial plan view of another display substrate provided in accordance with an embodiment of the present disclosure. As shown in Figure 12, each pixel group 250 may be located within a virtual square, and different first sub-pixels 211 may have the same area and size, different second sub-pixels 212 may have the same area and size, and different third sub-pixels 213 may have the same area and size.

[0166] In some examples, as shown in FIG12 , in a first direction, the distances between the geometric centers of adjacent pixels of the same sub-type are equal; in an arc direction, the distances between adjacent virtual blocks or pixel groups gradually increase.

[0167] Figure 13 is a partial plan view of another display substrate provided in an embodiment of the present disclosure. As shown in Figure 13, the display substrate 200 includes a base substrate 110 and a plurality of sub-pixels 210. The base substrate 110 includes a first display area 112, and the plurality of sub-pixels 210 are located in the first display area 112. The first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, with the length of the first side 112A being shorter than the length of the second side 112B. The plurality of sub-pixels 210 form a plurality of sub-pixel rows 220 arranged along a first direction. Each sub-pixel row 220 includes N sub-pixels 210 arranged along the extending direction of the first side 112A or the second side 112B. The N sub-pixels 210 included in each sub-pixel row 220 form a plurality of pixel groups 250. Each pixel group 250 includes a first sub-pixel 211, a second sub-pixel 212, and a third sub-pixel 213. The plurality of sub-pixel rows 220 are equidistantly arranged in the first direction. A first distance, i.e., a pixel pitch, is defined between the centers of two adjacent sub-pixels 210 in each sub-pixel row 220. The first distance in the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. In other words, the pixel pitch of the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases.

[0168] It should be noted that, unlike the display substrate shown in Figure 1, the above-mentioned sub-pixel rows are rows formed by pixel groups; the first distance between the centers of two adjacent sub-pixels 210 in each of the above-mentioned sub-pixel rows 220 may be the distance between the two first sub-pixels 211 in two adjacent pixel groups 250, or the distance between the two second sub-pixels in two adjacent pixel groups 250, or the distance between the two third sub-pixels in two adjacent pixel groups.

[0169] In the display substrate provided in the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with display screens having complex shapes, thereby having a wide range of application scenarios. In addition, in the case where the first display area has an irregular shape, by arranging multiple sub-pixel rows equidistantly in the first direction, a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and the first distance of the multiple sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the pixel arrangement structure, thereby optimizing the display effect. On the other hand, the pixel arrangement of the display substrate is more regular, which is convenient for driving.

[0170] In some examples, as shown in FIG13 , the first display area 112 is a fan-shaped fan-shaped display area 112. In this case, the first side 112A is a first curved side, the second side 112B is a second curved side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along an arc direction. It should be noted that the arc direction can be the extension direction of the first curved side or the second curved side; furthermore, the fan-shaped fan-shaped fan can be formed by removing the sharp corners.

[0171] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0172] In some examples, the base substrate 110 located in the fan-ring display area 112 can be curved along a first direction. This allows the display substrate to achieve a curved display. Furthermore, because the base substrate in the fan-ring display area can be curved along the first direction, the pixel distribution and brightness of the display substrate are visually more uniform. Furthermore, when the base substrate in the fan-ring display area is curved along the first direction, the display substrate can form a display screen with more complex and diverse shapes.

[0173] In some examples, as shown in FIG. 13 , in each pixel group 250 , the third sub-pixel 213 and the first sub-pixel 211 are arranged along a first direction and form a pixel pair, and the pixel pair and the second sub-pixel 212 are arranged along an arc direction.

[0174] In some examples, unlike the display substrate shown in FIG. 10 , as shown in FIG. 13 , the display substrate 200 is provided with no second spacers and only third spacers 123. Each third spacer 123 is located between two adjacent second sub-pixels 212 in the first direction. The plurality of third spacers 123 form a plurality of third spacer columns 133 arranged along an arcuate direction. Each third spacer column 133 includes a plurality of third spacers 123 arranged along a direction intersecting the arcuate direction. Within each third spacer column 133, the centers of the plurality of third spacers 123 are equidistantly spaced, and the extension directions of any two third spacer columns 133 intersect at a position where the first arcuate edge 112A extends away from the second arcuate edge 112B. Thus, the display substrate utilizes the gap between two adjacent second sub-pixels in the first direction to provide third spacers, thereby further effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0175] In some examples, as shown in FIG13 , in each third spacer column 133, the size of the third spacers 123 along the arc increases as the distance from the first arcuate edge 112A increases. This allows the display substrate to maintain a consistent area ratio of the third spacers in different regions of the display substrate, effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0176] In some examples, as shown in FIG13 , the areas of the same sub-pixels 210 vary within the first display region 112 , for example, increasing with increasing distance from the first curved edge 112A. Thus, the display substrate can improve brightness uniformity in the first display region.

[0177] In some examples, as shown in FIG13 , each sub-pixel 210 has a first size in the first direction and a second size in the arc direction. In a sub-pixel column 230, the M sub-pixels 210 have the same first size, and their second size increases as the distance from the first arc-shaped edge 112A increases. Thus, the display substrate can increase the area of ​​the same sub-pixel as the distance from the first arc-shaped edge increases, thereby improving brightness uniformity in the first display area.

[0178] In some examples, as shown in FIG13 , the first sub-pixel 211 is configured to emit light of a first color, the second sub-pixel 212 is configured to emit light of a second color, and the third sub-pixel 213 is configured to emit light of a third color. It should be noted that the shape of each sub-pixel shown in the embodiments of the present disclosure may be the shape of the emission region or light-emitting region of each sub-pixel, which may generally be defined by a pixel opening in a pixel-defining layer.

[0179] For example, the first color is green, the second color is blue, and the third color is red. Of course, the embodiments of the present disclosure include but are not limited to the above.

[0180] In some examples, as shown in FIG13 , the area of ​​the second sub-pixel 212 is larger than the area of ​​the third sub-pixel 213 and the area of ​​the first sub-pixel 211. Thus, the display substrate can balance the service life of various sub-pixels. Of course, the embodiments of the present disclosure include but are not limited to this. As the service life of different color luminescent materials changes, the area of ​​different sub-pixels can be set according to actual conditions.

[0181] In some examples, as shown in FIG. 13 , the shapes of the first sub-pixel 211 , the second sub-pixel 212 , and the third sub-pixel 213 may be rectangular.

[0182] In other examples, at least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 in FIG13 can be replaced with a circle, thereby effectively improving the color separation phenomenon under optical diffraction and optimizing the display effect. Of course, the shape of each sub-pixel in the embodiments of the present disclosure includes but is not limited to the ones described above, and the shape of each sub-pixel can be other shapes such as polygonal and elliptical.

[0183] In some examples, as shown in FIG. 13 , the number of first sub-pixels 211 , the number of second sub-pixels 212 , and the number of third sub-pixels 213 are the same.

[0184] Figure 14 is a partial plan view of another display substrate provided in accordance with an embodiment of the present disclosure. As shown in Figure 14, unlike the display substrate shown in Figure 13, this display substrate includes at least one sub-pixel 210. The edge of this sub-pixel 210 near the first curved edge 112A is larger than the edge farther from the first curved edge 112A. As a result, this display substrate allows the area of ​​the same sub-pixel to increase with distance from the first curved edge, thereby improving brightness uniformity in the first display area.

[0185] In some examples, as shown in FIG14 , the sub-pixel 210 (e.g., the second sub-pixel 212) may be shaped as an isosceles trapezoid, with the base of the isosceles trapezoid located on a side of the top away from the first curved edge 112A. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the second sub-pixel may also be other suitable shapes.

[0186] In some examples, as shown in FIG. 14 , taking the second sub-pixel 212 as an example, the shape of the second sub-pixel 212 is an isosceles trapezoid; in addition, different second sub-pixels 212 in the first direction have the same size.

[0187] FIG15 is a partial plan view of another display substrate provided in an embodiment of the present disclosure. As shown in FIG15 , the display substrate 200 includes a base substrate 110 and a plurality of sub-pixels 210. The base substrate 110 includes a first display area 112, and the plurality of sub-pixels 210 are located in the first display area 112. The first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, wherein the length of the first side 112A is less than the length of the second side 112B. The plurality of sub-pixels 210 form a plurality of sub-pixel rows 220 arranged along the first direction. Each sub-pixel row 220 includes N sub-pixels 210 arranged along the extension direction of the first side 112A or the second side 112B. The plurality of sub-pixel rows 220 are equidistantly arranged in the first direction. The centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch, between them. The first distance in the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases. That is, the pixel pitch of the plurality of sub-pixel rows 220 increases as the distance from the first side 112A increases.

[0188] As shown in Figure 15, different from the display substrate shown in Figures 1 and 10, in the first display area 112, the sub-pixel row 220 includes a first sub-pixel 211, a second sub-pixel 212 and a third sub-pixel 213 that are arranged in a circular manner; the first distance between the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 is the distance between two adjacent first sub-pixels 211, or the distance between two adjacent second sub-pixels 212, or the distance between two adjacent third sub-pixels 213.

[0189] In the display substrate provided in the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with display screens having complex shapes, thereby having a wide range of application scenarios. In addition, in the case where the first display area has an irregular shape, by arranging multiple sub-pixel rows equidistantly in the first direction, a first distance is provided between the centers of two adjacent sub-pixels in each sub-pixel row, and the first distance of the multiple sub-pixel rows increases as the distance from the first side increases, the display substrate can optimize the pixel arrangement structure, thereby optimizing the display effect. On the other hand, the pixel arrangement of the display substrate is more regular, which is convenient for driving.

[0190] In some examples, as shown in FIG15 , the first display area 112 is a fan-shaped fan-shaped display area 112. In this case, the first side 112A is a first curved side, the second side 112B is a second curved side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along an arc direction. It should be noted that the arc direction can be the extension direction of the first curved side or the second curved side; furthermore, the fan-shaped fan-shaped fan can be formed by removing the sharp corners.

[0191] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0192] In some examples, the base substrate 110 located in the fan-ring display area 112 can be curved along a first direction. This allows the display substrate to achieve a curved display. Furthermore, because the base substrate in the fan-ring display area can be curved along the first direction, the pixel distribution and brightness of the display substrate are visually more uniform. Furthermore, when the base substrate in the fan-ring display area is curved along the first direction, the display substrate can form a display screen with more complex and diverse shapes.

[0193] In some examples, as shown in FIG15 , the display substrate 200 includes a plurality of fifth spacers 125 ; each fifth spacer 125 is located between the first sub-pixel 211 and the second sub-pixel 212 , or between the second sub-pixel 212 and the third sub-pixel 213 , or between the third sub-pixel 213 and the first sub-pixel 211 . The plurality of fifth spacers 125 form a plurality of fifth spacer columns 135 arranged along an arc direction. Each fifth spacer column 135 includes a plurality of fifth spacers 125 arranged along a direction intersecting the arc direction. Within each fifth spacer column 135 , the centers of the plurality of fifth spacers 125 are equidistantly spaced, and the extending directions of any two fifth spacer columns 135 intersect at a position where the first arcuate edge 112A is spaced away from the second arcuate edge 112B. Thus, the display substrate further features spacer positioning design that optimizes spacer distribution, effectively supporting and protecting the mask and preventing damage to the substrate to be deposited and the mask.

[0194] In some examples, as shown in FIG15 , in each fifth spacer column 135, the size of the fifth spacer 135 along the arc increases as the distance from the first arcuate edge 112A increases. Thus, the display substrate can maintain a consistent area ratio of the second spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0195] In some examples, as shown in FIG. 15 , the number of first sub-pixels 211 , the number of second sub-pixels 212 , and the number of third sub-pixels 213 are the same.

[0196] In some examples, as shown in FIG15 , the first sub-pixel 211 is in a diamond shape, the second sub-pixel 212 is in a hexagonal shape, and the third sub-pixel 213 is in a hexagonal shape. Of course, the embodiments of the present disclosure include but are not limited to these, and the first sub-pixel, the second sub-pixel, and the third sub-pixel may also adopt other suitable shapes.

[0197] In other examples, at least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 in FIG. 15 can be replaced with a circle, thereby effectively improving the color separation phenomenon under optical diffraction and optimizing the display effect. Of course, the shape of each sub-pixel in the embodiments of the present disclosure includes but is not limited to the ones described above, and the shape of each sub-pixel can be other shapes such as polygonal and elliptical.

[0198] In some examples, as shown in FIG15 , the first sub-pixel 211 is configured to emit light of a first color, the second sub-pixel 212 is configured to emit light of a second color, and the third sub-pixel 213 is configured to emit light of a third color. It should be noted that the shape of each sub-pixel shown in the embodiments of the present disclosure may be the shape of the emission region or light-emitting region of each sub-pixel, which may generally be defined by a pixel opening in a pixel-defining layer.

[0199] For example, the first color is green, the second color is blue, and the third color is red. Of course, the embodiments of the present disclosure include but are not limited to the above.

[0200] In some examples, as shown in FIG15 , the area of ​​the second sub-pixel 212 is larger than the area of ​​the third sub-pixel 213 and the area of ​​the first sub-pixel 211. Thus, the display substrate can balance the service life of various sub-pixels. Of course, the embodiments of the present disclosure include but are not limited to this. As the service life of different color luminescent materials changes, the area of ​​different sub-pixels can be set according to actual conditions.

[0201] An embodiment of the present disclosure also provides another display substrate. The position and size of the spacers are designed in this display substrate. Figure 16 is a partial planar schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in Figure 16, the display substrate 200 includes a base substrate 110 and a plurality of spacers 120; the base substrate 110 includes a first display area 112, and the plurality of spacers 120 are located in the first display area 112; the first display area 112 includes a first side 112A and a second side 112B arranged along a first direction, and the length of the first side 112A is less than the length of the second side 112B.

[0202] As shown in Figure 16, multiple spacers 120 form multiple spacer columns 130 arranged along the extension direction of the first edge 112A or the second edge 112B, and each spacer column 130 includes multiple spacers 120 arranged along the first direction; in each spacer column 130, the centers of the multiple spacers 120 are arranged equidistantly, and the extension directions of any two spacer columns 130 intersect at a position on the first edge 112A away from the second edge 112B.

[0203] In the display substrate provided by the embodiments of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to display devices with complex display screens, thus having a wide range of application scenarios. In addition, since the centers of the multiple spacers in each spacer column are arranged equidistantly, the extension directions of any two spacer columns intersect at a position where the first side is far from the second side. The display substrate also designs the spacer positions to make the spacer distribution more reasonable, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0204] It should be noted that, because the length of the first side of the first display area is less than the length of the second side, the shape of the first display area is not a conventional rectangle or square, but an irregular shape. In addition, the center of the spacer can be a geometric center, and the geometric center can be allowed to have a certain error or range.

[0205] In some examples, as shown in FIG16 , the spacer 120 has a third dimension in the first direction, and the spacer 120 has a fourth dimension in the extension direction of the first side 112A or the second side 112B. In each spacer column 130 , the fourth dimension of the spacer 120 increases as the distance from the first side 112A increases. Thus, the display substrate can maintain a consistent area ratio of the spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate. Furthermore, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned arrangement to avoid electrostatic adsorption, thereby avoiding damage to the delicate metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0206] In some examples, as shown in FIG16 , each spacer 120 includes a first spacer edge 120A near the first side 112A and a second spacer edge 120B near the second side 112B, with the first spacer edge 120A and the second spacer edge 120B being disposed opposite each other. In each spacer row 130, the first spacer edge 120A of the spacer 120 increases in size as the distance from the first side 112A increases, and in each spacer row 130, the second spacer edge 120B of the spacer 120 increases in size as the distance from the first side 112A increases. Thus, the size or area of ​​the spacers can be increased by increasing the sizes of the first spacer edge and the second spacer edge, respectively.

[0207] In some examples, as shown in Figure 16, for a spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. This arrangement further maintains a consistent area ratio of spacers in different regions of the display substrate, thereby effectively supporting and protecting the mask and preventing damage to the substrate to be evaporated and the mask.

[0208] In some examples, as shown in FIG16 , the first display area 112 is a fan-ring display area 112 having a fan-ring shape. In this case, the first side 112A is a first arc-shaped side, the second side 112B is a second arc-shaped side, and the N sub-pixels 210 in each sub-pixel row 220 are arranged along the arc direction. It should be noted that the arc direction may be the extension direction of the first arc-shaped side or the second arc-shaped side; in addition, the fan-ring shape may be a shape formed by removing the acute angle of the fan. In addition, the shape of the first display area includes but is not limited to a fan-ring shape, and may also be a trapezoid, a quadrilateral, etc., as long as the length of the first side is less than the length of the second side.

[0209] In the display substrate provided in this example, since the first display area has a fan-ring display area, the display substrate can provide a display area with a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes, so that it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.
