Description

Technical Field

[0002] With the diversified development of the application fields and product forms of organic light-emitting diode (OLED) display substrates, people's demand for electronic products using organic light-emitting diode display substrates is also increasing. These electronic products include smart phones, TVs, computers, tablets, navigation systems, car central control screens, and smart watches.

[0003] On the other hand, in the process of manufacturing an organic light-emitting diode display substrate, an evaporation process is usually required to form an organic light-emitting layer in the organic light-emitting diode display substrate. The evaporation process requires a fine metal mask (FineMetal Mask, FMM) to control the evaporation position of the organic light-emitting layer of each sub-pixel. A spacer is arranged above the pixel definition layer (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. Summary of the invention

[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the 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.

[0066] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0067] With the diversified development of the application fields and product forms of organic light-emitting diode (OLED) display substrates, the design of organic light-emitting diode display substrates has become more varied and complex, and needs to have complex and varied shapes and structures. For example, for wearable smart watches, the organic light-emitting diode display substrate is not only required to display on the top plane of the smart watch, but also needs to display images normally on the side or the curved part of the side of the smart watch. Therefore, it is necessary to design the pixel arrangement structure of the organic light-emitting diode display substrate to cope with the complex and varied shapes and structures, so as to optimize the display effect.

[0068] On the other hand, the spacers 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 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. Therefore, when the display substrate has a complex and changeable shape and structure, how to design the position and size of the spacers is also one of the key issues to improve product yield and display effect.

[0069] In this regard, an embodiment of the present disclosure provides a display substrate, which includes a substrate and a plurality of sub-pixels; the substrate includes a first display area, and the plurality of sub-pixels are located in the first display area; the plurality of first display areas include a first side and a second side arranged along a first direction, and 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, and each of the sub-pixel rows includes N sub-pixels arranged along the extension direction of the first side or the second side; the plurality of sub-pixel rows are arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels in each of the sub-pixel rows have a first distance, and 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, the centers of two adjacent sub-pixels in each of the sub-pixel rows have a first distance, and 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.

[0070] 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 are located in the first display area; the first display area includes a first side and a second side arranged along a first direction, and the length of the first side is less than the length of the second side; the plurality of spacers form a plurality of spacer rows arranged along the first direction, and each of the spacer rows includes K spacers arranged along the extension direction of the first side or the second side; the plurality of spacer rows are arranged equidistantly in the first direction, and there is a second distance between the centers of two adjacent spacers in each of the spacer rows, 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.

[0071] The embodiment of 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.

[0072] The display substrate and the display device provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0073] An embodiment of the present disclosure provides a display substrate; Figure 1 FIG. 1 is a partial plan view of a display substrate provided by an embodiment of the present disclosure. Figure 1As shown, the display substrate 200 includes a substrate 110 and a plurality of sub-pixels 210; the 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 the first direction, and 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, where N is a positive integer greater than or equal to 2; the plurality of sub-pixel rows 220 are arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch; 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, since 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 common rectangle or square, but an irregular shape. In addition, the center of the sub-pixel may be a geometric center, and the geometric center may allow a certain error or range; for example, the geometric center of the sub-pixel may be a range with a radius of 3 μm with the geometric center of the sub-pixel as the center.

[0074] 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 a display device with a display screen having a complex shape, thereby having a wide range of application scenarios. Moreover, in the case where the first display area has an irregular shape, by arranging a plurality of 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 plurality of 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.

[0075] In some examples, such as Figure 1 As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the first side 112A is a first arc side, the second side 112B is a second arc 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 can be the extension direction of the first arc side or the second arc side; in addition, the fan-ring shape can be a shape formed by removing the acute angle of the fan.

[0076] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0077] In some examples, such as Figure 1 As shown, 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.

[0078] In some examples, the base substrate 110 located in the fan-ring display area 112 can be bent along the first direction. Thus, the display substrate can also realize curved display, and because the base substrate in the fan-ring display area can be bent along the first direction, the pixel distribution and brightness of the display substrate are more uniform visually. In addition, when the base substrate in the fan-ring display area is bent along the first direction, the display substrate can form a display screen with more complex and richer shapes.

[0079] In some examples, such as Figure 1 As shown, the plurality of sub-pixels 210 include a plurality of sub-pixel columns 230 arranged along the arc direction, each sub-pixel column 230 includes M sub-pixels 210 arranged along a direction intersecting the arc direction, where M is a positive integer greater than or equal to 2; the extension directions of two sub-pixel columns 230 intersect at an intersection point, and the intersection point is located on the side of the first arc-shaped edge 112A away from the second arc-shaped edge 112B. As a result, the distribution of the sub-pixels in the first display area is more uniform, thereby improving the display quality.

[0080] In some examples, such as Figure 1 As shown, the first arc-shaped side 112A has a first virtual center, the second arc-shaped side 112B has a second virtual center, the first virtual center and the second virtual center coincide with each other; the extension direction of any two sub-pixel columns 230 intersects at the first virtual center or the second virtual center. With such a configuration, the display substrate can make the distribution of the sub-pixel columns more uniform, thereby improving the display quality.

[0081] In some examples, such as Figure 1 As shown, the centers of the N sub-pixels 210 in each sub-pixel row 220 may be located on a virtual arc with the first virtual center or the second virtual center as the center. Of course, the embodiments of the present disclosure include but are not limited to this.

[0082] In some examples, such as Figure 1 As shown, in each sub-pixel column 230 , the centers of the M sub-pixels 210 are arranged equidistantly, so that the uniformity of pixel distribution can be further improved, thereby improving the display quality.

[0083] In some examples, such as Figure 1 As shown, the sub-pixel 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 Figure 1 The shape of each sub-pixel shown in the figure may be the shape of an emission region or a light-emitting region of each sub-pixel, and the light-emitting region may generally be defined by a pixel opening in a pixel defining layer.

[0084] 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 this.

[0085] In some examples, such as Figure 1 As shown, the number of the first sub-pixels 211 is twice the number of the second sub-pixels 212 or the third sub-pixels 213. Therefore, the display substrate can improve the resolution (PPI) through a pixel borrowing algorithm.

[0086] In some examples, such as Figure 1 As shown, the plurality of sub-pixel rows 220 include a plurality of first sub-pixel rows 220A and second sub-pixel rows 220B arranged alternately; each first sub-pixel row 220A includes a plurality of first sub-pixels 211 arranged along an arc direction, 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 direction. In each second sub-pixel row 220B, a plurality of second sub-pixels 212 and a plurality of third sub-pixels 213 are arranged alternately. Thus, the display substrate can facilitate pixel borrowing, and can make full use of process accuracy and improve deposition stability.

[0087] In some examples, such as Figure 1 As shown, the areas of the multiple first sub-pixels 211 in the first pixel row 220A are approximately equal, the areas of the multiple second sub-pixels 212 in the second sub-pixel row 220B are approximately equal, and the areas of the multiple third sub-pixels 213 in the second sub-pixel row 220B are approximately equal.

[0088] In some examples, such as Figure 1 As shown, 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.

[0089] In some examples, such as Figure 1 As shown, the distance between any two adjacent first sub-pixels 211 in each first sub-pixel row 220A is equal, and the distance between the second sub-pixel 212 and 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.

[0090] In some examples, such as Figure 1 As shown, the shape of the first sub-pixel 211 includes a long strip with an extension direction; in each first pixel row 220A, the extension directions of two adjacent first sub-pixels 211 intersect. Thus, the display substrate can improve the compactness of pixel arrangement, improve display effects, and prevent defects such as vertical lines.

[0091] In some examples, such as Figure 1 As shown, in each first pixel row 220A, the extension directions of two adjacent first sub-pixels 211 are perpendicular to each other.

[0092] In some examples, such as Figure 1 As shown, the shape of the second sub-pixel 212 includes an arc-shaped edge 2121 and a right-angled edge 2122 arranged opposite to each other. In each second pixel row 220B, the arrangement order of the arc-shaped edge 2121 and the right-angled edge 2122 of two adjacent second sub-pixels 212 is different, for example, opposite. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the arc-shaped edge smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels by setting the second sub-pixel with the above-mentioned arc-shaped edge and right-angled edge to achieve a better display effect.

[0093] In some examples, such as Figure 1 As shown, the shape of the second sub-pixel 212 includes a first corner 212A and a second corner 212B that are arranged relatively, and 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 an axisymmetric shape. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the edge of the second corner smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels by setting the second sub-pixel having the above-mentioned first corner and second corner to achieve a better display effect. It should be noted that the above-mentioned color index can be parameters such as brightness, color gamut, color temperature, wavelength, etc. of the light emitted by the sub-pixel.

[0094] In some other examples, the shape of the second sub-pixel may also be circular, so as to effectively improve the color separation phenomenon under optical diffraction and optimize the display effect; at the same time, the shapes of the first sub-pixel and the third sub-pixel may also be circular, so as to further improve the color separation phenomenon under optical diffraction and optimize the display effect. Of course, the shape of each sub-pixel in the embodiment of the present disclosure includes but is not limited to the above-described case, and the shape of each sub-pixel may be other shapes such as polygonal and elliptical.

[0095] For example, Figure 1 As shown, 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 .

[0096] In some examples, such as Figure 1 As shown, the multiple sub-pixels 210 include a plurality of first sub-pixel columns 230A and a plurality of second sub-pixel columns 230B alternately arranged along the 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 the 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.

[0097] In some examples, such as Figure 1 As shown, the shape of the first sub-pixel 211 includes a long strip with an extension direction; in each first pixel column 230A, the extension directions of two adjacent first sub-pixels 211 intersect. Thus, the display substrate can improve the compactness of pixel arrangement, improve display effects, and prevent defects such as vertical lines.

[0098] For example, Figure 1 As shown, 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.

[0099] In some examples, such as Figure 1 As shown, the shape of the second sub-pixel 212 includes an arc-shaped edge 2121 and a right-angled edge 2122 arranged opposite to each other. In each second pixel column 230B, the arrangement order of the arc-shaped edges 2121 and the right-angled edges 2122 of two adjacent second sub-pixels 212 is different, for example, opposite. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the arc-shaped edges smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels by setting the second sub-pixels with the above-mentioned arc-shaped edges and right-angled edges to achieve a better display effect.

[0100] In some examples, such as Figure 1 As shown, the display substrate 200 also includes a plurality of spacers 120, which are located in the fan-ring display area 112; the plurality of spacers 120 form a plurality of spacer columns 130 arranged along the 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 direction of any two spacer columns 130 intersects at a position where the first arc edge 112A is away from the second arc edge 112B. Therefore, the display substrate also designs the position of the spacers so that the distribution of the spacers is more reasonable, so as to effectively support and protect the mask plate, and prevent 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.

[0101] In some examples, such as Figure 1 As shown, in each spacer column 130, the size of the spacer 120 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. As a result, the display substrate can maintain a consistent area ratio of the spacers in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate. In addition, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned setting to avoid electrostatic adsorption, thereby avoiding damage to the fine metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0102] In some examples, such as Figure 1 As shown, each spacer 120 includes a first spacer edge 120A close to the first arc-shaped edge 112A and a second spacer edge 120B close to the second arc-shaped edge 112B, and the first spacer edge 120A and the second spacer edge 120B are arranged opposite to each other; in each spacer column 130, the first spacer edge 120A of the spacer 120 increases as the distance from the first arc-shaped edge 112A increases, and in each spacer column 130, the second spacer edge 120B of the spacer 120 increases as the distance from the first arc-shaped edge 112A increases. Thus, the size or area of ​​the spacer is increased by respectively increasing the size of the first spacer edge and the second spacer edge.

[0103] In some examples, such as Figure 1 As shown, for one spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. With such a configuration, the display substrate can further maintain the consistent area ratio of the spacers in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0104] In some examples, such as Figure 1 As shown, the spacer 120 can be a first spacer 121, each first spacer 121 is located between two adjacent first sub-pixels 211; multiple first spacers 121 form multiple first spacer columns 131 arranged along the arc direction, each first spacer column 131 includes multiple first spacers 121 arranged along the direction intersecting the arc direction; in each first spacer column 131, the centers of multiple first spacers 121 are arranged equidistantly, and the extension directions of any two first spacer columns 131 intersect at the position where the first arc edge 112A is away from the second arc edge 112B. Therefore, the display substrate also designs the position of the spacers so that the distribution of the spacers is more reasonable, so that the mask plate can be effectively supported and protected, and the substrate to be evaporated and the mask plate can be prevented from being damaged.

[0105] In some examples, such as Figure 1 As shown, in each first spacer column 131, the size of the first spacer 121 in the arc direction increases as the distance from the first arc-shaped edge 112A increases. As a result, the display substrate can maintain a consistent area ratio of the first spacer in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate. In addition, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned setting to avoid electrostatic adsorption, thereby avoiding damage to the fine metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0106] Figure 2 This is a comparison diagram of the spacers in the first display area of ​​a display substrate provided by one embodiment of the present disclosure and the spacers in other display areas. Figure 2 As shown, in each spacer column 130 in the first display area 112, the centers of multiple spacers 120 are arranged equidistantly, and the size of the spacers 120 along the arc direction increases with the increase of the distance from the first arc-shaped edge 112A; in other display areas (such as the second display area described later), the size of the spacers remains unchanged.

[0107] In some examples, such as Figure 2 As shown, each spacer 120 includes a first spacer edge 120A and a second spacer edge 120B that are arranged opposite to each other; in each spacer column 130, the first spacer edge 120A of the spacer 120 gradually increases, and in each spacer column 130, the second spacer edge 120B of the spacer 120 gradually increases. Thus, the size or area of ​​the spacer is increased by increasing the size of the first spacer edge and the second spacer edge respectively.

[0108] In some examples, such as Figure 2As shown, for one spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. With such a configuration, the display substrate can further maintain the consistent area ratio of the spacers in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0109] Figure 3 A cross-sectional schematic diagram of a display substrate provided according to an embodiment of the present disclosure. Figure 3 For along Figure 1 A schematic cross-sectional view of the extending direction of the septum pad array; Figure 3 As shown, 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 the base substrate 110. The pixel driving circuit 150 is disposed on the base substrate 110 and may include devices such as thin film transistors and capacitors; the first electrode 160 is connected to the output end of the pixel driving circuit 150, so that the current or voltage output by the pixel driving circuit 150 can be loaded; the pixel defining layer 170 is disposed on the 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 in the pixel opening 175 of the pixel defining layer 170, and contacts the first electrode 160 through the pixel opening 175. At this time, the portion or region of the light-emitting functional layer 180 contacting the first electrode 160 through the pixel opening 175 can emit light under the electrical drive of 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 where the light-emitting functional layer contacts the first electrode through the pixel opening. It should be noted that a typical display substrate may also 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.

[0110] In some examples, such as Figure 3 As shown, the display substrate 200 further includes spacers 120 located on the pixel defining layer 170 and between the pixel openings 175. In the same spacer column 130, the geometric centers of the spacers 120 are arranged equidistantly, and the dimensions of the spacers 120 in the extending direction of the spacer column 130 remain unchanged.

[0111] In some examples, such as Figure 3 As shown, the display substrate 200 further includes a buffer layer 142 located on the base substrate 110 . The buffer layer 142 can modify defects on the base substrate 110 , thereby improving the quality of subsequent rubbing.

[0112] In some examples, such as Figure 3As shown, the display substrate 200 further includes a planarization 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 planarization layer 145 away from the substrate 110 and is connected to the pixel driving circuit 150 through a via hole in the planarization layer 145.

[0113] Figure 4 It is a partial plan view of a display substrate provided by an embodiment of the present disclosure. Figure 4 Only the arrangement of the first sub-pixels is shown. As Figure 4 shown, in the first sub-pixel row 220A composed of a plurality of first sub-pixels 211, the geometric centers of the plurality of first sub-pixels 211 can be located on the same circular arc. In the first sub-pixel column 230A composed of a plurality of first sub-pixels 211, the geometric centers of the plurality of first sub-pixels 211 are arranged at equal distances.

[0114] In some examples, as Figure 4 shown, the plurality of 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 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.

[0115] It should be noted that the above content takes Figure 4 the first sub-pixel as an example to illustrate the arrangement of the sub-pixels. The arrangements of the second sub-pixel and the third sub-pixel may be the same as or similar to that of the first sub-pixel.

[0116] Figure 5 It is a schematic diagram of a display substrate provided by an embodiment of the present disclosure. As Figure 5 shown, the substrate 110 further includes a second display area 114, and the shape of the second display area 114 may 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.

[0117] For example, as Figure 5As shown, the display substrate can form a ring-shaped display area through four first display areas 112 and four second display areas 114, and is applied to the frame of the display device, so that the frame of the display device can also display content.

[0118] It should be noted that the base substrate of the display substrate including multiple display areas may be continuous or spliced, which is not limited in the embodiments of the present disclosure.

[0119] Figure 6 FIG. 1 is a schematic diagram of another display substrate provided by an embodiment of the present disclosure. Figure 6 As shown, the fan ring shape in the embodiment of the present disclosure includes a fan ring shape in which the angle between the two straight sides is less than 180 degrees, and also includes Figure 6 The angle between the two straight sides shown is greater than 180 degrees. In this case, the shape of the first display area 112 can be a circular ring including a notch. In addition, the fan ring shape provided by the embodiment of the present disclosure also includes a circular ring, in which case the angle between the two straight sides of the fan ring shape is 360 degrees.

[0120] An embodiment of the present disclosure further provides a display device. Figure 7 Schematic diagram of a display device provided by an embodiment of the present disclosure. Figure 7 As shown, the display device 500 includes the above-mentioned display substrate 200. 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.

[0121] In some examples, such as Figure 7 As shown, the display device 500 includes a first display screen 510 and a second display screen 520; the second display screen 520 is arranged around the first display screen 510; the second display screen 520 includes the above-mentioned display substrate 200, that is, the second display screen 520 adopts the above-mentioned display substrate 200. Therefore, the second display screen of the display device allows the frame of the display device to be displayed, thereby greatly improving the display effect.

[0122] In some examples, such as Figure 7 As shown, the second display screen 520 can form a rectangular ring-shaped display area through four first display areas 112 and four second display areas 114.

[0123] In some examples, such as Figure 7As shown, 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, and the non-display area 514 of the first display screen 510 is connected to the non-display area 118 of the second display screen 520, thereby improving space utilization.

[0124] In some examples, such as Figure 7 As shown, the display device 500 further includes an annular cover plate 530, which covers the non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520, so that the non-display area is protected by the annular cover plate to prevent light leakage and other defects. In addition, the display device can also improve the appearance quality of the product by improving the stability of the product through the annular cover plate.

[0125] In some examples, such as Figure 7 As shown, the first display screen 510 includes a back surface and a light emitting surface opposite to the back surface, the second display screen 520 is bent from a first plane where the light emitting surface is located to a second plane where the back surface is located, and the first side 112A of the first display area 112 of the second display screen 520 is located on the first plane or closer to the first plane than the second side 112B. Therefore, the display device can also fully cover the frame of the display device by bending the second display screen, and further improve the display effect.

[0126] For example, the display device may be a smart watch. 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 navigator, a car display, an electronic picture frame, a tablet computer, etc.

[0127] Figure 8 FIG. 1 is a schematic diagram of another display device provided by an embodiment of the present disclosure. Figure 8 As shown, the display device 500 includes the above-mentioned display substrate 200. 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.

[0128] In some examples, such as Figure 8 As shown, 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; the second display screen 520 includes the above-mentioned display substrate 200, that is, the second display screen 520 adopts the above-mentioned display substrate 200. Therefore, the second display screen of the display device allows the frame of the display device to be displayed, thereby greatly improving the display effect.

[0129] In some examples, such as Figure 8 As shown, the first display area 112 of the display substrate 200 used by the second display screen 520 may be a circular display area, or a plurality of 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.

[0130] In some examples, such as Figure 8 As shown, 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, and the non-display area 514 of the first display screen 510 is connected to the non-display area 118 of the second display screen 520, thereby improving space utilization.

[0131] In some examples, such as Figure 8 As shown, the display device 500 further includes an annular cover plate 530, which covers the non-display area 514 of the first display screen 510 and the non-display area 118 of the second display screen 520, so that the non-display area is protected by the annular cover plate to prevent light leakage and other defects. In addition, the display device can also improve the appearance quality of the product by improving the stability of the product through the annular cover plate.

[0132] In some examples, such as Figure 8 As shown, the first display screen 510 includes a back surface and a light emitting surface opposite to the back surface, the second display screen 520 is bent from a first plane where the light emitting surface is located to a second plane where the back surface is located, and the first side 112A of the first display area 112 of the second display screen 520 is located on the first plane or closer to the first plane than the second side 112B. Therefore, the display device can also fully cover the frame of the display device by bending the second display screen, and further improve the display effect.

[0133] For example, the display device may be a smart watch. 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 navigator, a car display, an electronic picture frame, a tablet computer, etc.

[0134] An embodiment of the present disclosure also provides another display substrate. Fig. 9 A partial plan view of another display substrate provided by an embodiment of the present disclosure; Fig.10 A partial plan view of another display substrate provided in one embodiment of the present disclosure. It is worth noting that the pixel arrangement structure and the spacer arrangement structure in the first display area of ​​the display substrate described below can be used to replace Figure 1-Figure 6The pixel arrangement structure and the spacer arrangement structure in the first display area of ​​the display substrate shown in any one of the above are applied to Figure 7 and Figure 8 In the display device shown.

[0135] like Fig. 9 As shown, Fig. 9 The sub-pixel arrangement structure in the regular display area is shown. 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 the first direction.

[0136] like Fig.10 As shown, 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 edge 112A and a second edge 112B arranged along a first direction, and the length of the first edge 112A is less than the length of the second edge 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 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 arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch; 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.

[0137] It should be noted that Figure 1 What is different from the display substrate shown is that 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.

[0138] 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 a display device with a display screen having a complex shape, thereby having a wide range of application scenarios. Moreover, in the case where the first display area has an irregular shape, by arranging a plurality of 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 plurality of 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.

[0139] In some examples, such as Fig.10 As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the first side 112A is a first arc side, the second side 112B is a second arc 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 can be the extension direction of the first arc side or the second arc side; in addition, the fan-ring shape can be a shape formed by removing the acute angle of the fan.

[0140] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0141] In some examples, such as Fig.10 As shown, 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.

[0142] In some examples, the base substrate 110 located in the fan-ring display area 112 can be bent along the first direction. Thus, the display substrate can also realize curved display, and because the base substrate in the fan-ring display area can be bent along the first direction, the pixel distribution and brightness of the display substrate are more uniform visually. In addition, when the base substrate in the fan-ring display area is bent along the first direction, the display substrate can form a display screen with more complex and richer shapes.

[0143] In some examples, such as Fig.10 As shown, in each pixel group 250, the third sub-pixel 213 and the first sub-pixel 211 are arranged along a first direction to form a pixel pair, and the pixel pair and the second sub-pixel 212 are arranged along an arc direction.

[0144] In some examples, such as Fig.10As shown, the display substrate 200 includes a plurality of second spacers 122; each second spacer 122 is located between the pixel pair and the second sub-pixel 212; the plurality of second spacers 122 form a plurality of second spacer columns 132 arranged along the arc direction, and each second spacer column 132 includes a plurality of second spacers 122 arranged along a direction intersecting the arc direction; in each second spacer column 132, the centers of the plurality of second spacers 122 are arranged equidistantly, and the extension directions of any two second spacer columns 132 intersect at the position where the first arc edge 112A is away from the second arc edge 112B. Therefore, the display substrate also designs the position of the spacers so that the distribution of the spacers is more reasonable, so that the mask plate can be effectively supported and protected, and the substrate to be evaporated and the mask plate can be prevented from being damaged.

[0145] In some examples, such as Fig.10 As shown, in each second spacer column 132, the size of the second spacer 122 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. As a result, the display substrate can maintain the same area ratio of the second spacer in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0146] In some examples, such as Fig.10 As shown, the display substrate 200 also includes a plurality of third spacers 123, each of which is located between two adjacent second sub-pixels 212 in the first direction, and the plurality of third spacers 123 form a plurality of third spacer columns 133 arranged along the arc direction, and each third spacer column 133 includes a plurality of third spacers 123 arranged along a direction intersecting the arc direction; in each third spacer column 133, the centers of the plurality of third spacers 123 are arranged equidistantly, and the extension directions of any two third spacer columns 133 intersect at the position where the first arc edge 112A is away from the second arc edge 112B. Thus, the display substrate also increases the number of spacers by utilizing the gap between two adjacent second sub-pixels in the first direction, so as to further effectively support and protect the mask plate, and prevent damage to the substrate to be evaporated and the mask plate.

[0147] In some examples, such as Fig.10 As shown, in each third spacer column 133, the size of the third spacer 123 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. Thus, the display substrate can keep the area proportion of the third spacer in different regions on the display substrate consistent, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0148] In some examples, such as Fig.10As shown, the dimension of the third spacer 123 along the arc direction is greater than the dimension of the third spacer 123 in the extension direction of the third spacer column 133 to which it belongs. Therefore, the third spacer can fully utilize the space and improve the resolution.

[0149] In some examples, such as Fig.10 As shown, 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 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.

[0150] 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 this.

[0151] In some examples, such as Fig.10 As shown, the area of ​​the second sub-pixel 212 is respectively 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.

[0152] In some examples, such as Fig.10 As shown, the shapes of the first sub-pixel 211 , the second sub-pixel 212 and the third sub-pixel 213 may be rectangular.

[0153] In other examples, Fig.10 At least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 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 embodiment of the present disclosure includes but is not limited to the above-described case, and the shape of each sub-pixel can be other shapes such as a polygon and an ellipse.

[0154] In some examples, such as Fig.10 As shown, the number of the first sub-pixels 211 , the number of the second sub-pixels 212 , and the number of the third sub-pixels 213 are the same.

[0155] Fig.11 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.11As shown, 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 edge 112A and a second edge 112B arranged along a first direction, and the length of the first edge 112A is less than the length of the second edge 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 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 arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch; 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 two first sub-pixels 211 in two adjacent pixel groups 250, or the distance between two second sub-pixels in two adjacent pixel groups 250, or the distance between two third sub-pixels in two adjacent pixel groups.

[0156] 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 a display device with a display screen having a complex shape, thereby having a wide range of application scenarios. Moreover, in the case where the first display area has an irregular shape, by arranging a plurality of 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 plurality of 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.

[0157] In some examples, such as Fig.11 As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the first side 112A is a first arc side, the second side 112B is a second arc 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 can be the extension direction of the first arc side or the second arc side; in addition, the fan-ring shape can be a shape formed by removing the acute angle of the fan.

[0158] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0159] In some examples, such as Fig.11 As shown, 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.

[0160] In some examples, such as Fig.11 As shown, Fig.10 The display substrate shown is different in that the display substrate 200 is not provided with the second spacer and the third spacer. The display substrate 200 includes a plurality of fourth spacers 124, each of which is located between two adjacent pixel groups 250; the plurality of fourth spacers 124 form a plurality of fourth spacer columns 134 arranged along the arc direction, each of which includes a plurality of fourth spacers 124 arranged along a direction intersecting the arc direction; in each of which, the centers of the plurality of fourth spacers 124 are arranged equidistantly, and the extension directions of any two fourth spacer columns 134 intersect at a position where the first arc side 112A is away from the second arc side 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 color deviation and other defects; 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.

[0161] In some examples, such as Fig.11 As shown, in each fourth spacer column 134, the size of the fourth spacer 124 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. Thus, the display substrate can keep the fourth spacer in different areas on the display substrate with the same area ratio, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0162] In some examples, such as Fig.11 As shown, the shape of the fourth spacer 124 may 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 may also be any other shape.

[0163] Fig.12 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.12As shown, each pixel group 250 may be located in a virtual square, and different first sub-pixels 211 have the same area and size, different second sub-pixels 212 have the same area and size, and different third sub-pixels 213 have the same area and size.

[0164] In some examples, such as Fig.12 As shown, in the first direction, the distances between the geometric centers of adjacent pixels of the same sub-type are equal; in the arc direction, the distances between adjacent virtual blocks or pixel groups gradually increase.

[0165] Fig.13 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.13 As shown, 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 edge 112A and a second edge 112B arranged along a first direction, and the length of the first edge 112A is less than the length of the second edge 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 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 arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, i.e., a pixel pitch; 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.

[0166] It should be noted that Figure 1 What is different from the display substrate shown is that 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.

[0167] 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 a display device with a display screen having a complex shape, thereby having a wide range of application scenarios. Moreover, in the case where the first display area has an irregular shape, by arranging a plurality of 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 plurality of 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.

[0168] In some examples, such as Fig.13 As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the first side 112A is a first arc side, the second side 112B is a second arc 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 can be the extension direction of the first arc side or the second arc side; in addition, the fan-ring shape can be a shape formed by removing the acute angle of the fan.

[0169] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0170] In some examples, the base substrate 110 located in the fan-ring display area 112 can be bent along the first direction. Thus, the display substrate can also realize curved display, and because the base substrate in the fan-ring display area can be bent along the first direction, the pixel distribution and brightness of the display substrate are more uniform visually. In addition, when the base substrate in the fan-ring display area is bent along the first direction, the display substrate can form a display screen with more complex and richer shapes.

[0171] In some examples, such as Fig.13 As shown, in each pixel group 250, the third sub-pixel 213 and the first sub-pixel 211 are arranged along a first direction to form a pixel pair, and the pixel pair and the second sub-pixel 212 are arranged along an arc direction.

[0172] In some examples, Fig.10 The display substrate shown is different from that shown in FIG. Fig.13As shown, the display substrate 200 is not provided with a second spacer, but only with a third spacer 123. Each third spacer 123 is located between two second sub-pixels 212 adjacent in the first direction, and a plurality of third spacers 123 form a plurality of third spacer columns 133 arranged along the arc direction, and each third spacer column 133 includes a plurality of third spacers 123 arranged along a direction intersecting the arc direction; in each third spacer column 133, the centers of the plurality of third spacers 123 are arranged equidistantly, and the extension directions of any two third spacer columns 133 intersect at the position where the first arc edge 112A is away from the second arc edge 112B. Therefore, the display substrate also uses the gap between two adjacent second sub-pixels in the first direction to set the third spacer, so as to further effectively support and protect the mask plate, and prevent the substrate to be evaporated and the mask plate from being damaged.

[0173] In some examples, such as Fig.13 As shown, in each third spacer column 133, the size of the third spacer 123 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. Thus, the display substrate can keep the area proportion of the third spacer in different regions on the display substrate consistent, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0174] In some examples, such as Fig.13 As shown, in the first display area 112, the areas of the same sub-pixels 210 are different, for example, increasing with the increase of the distance from the first arc-shaped edge 112A. Thus, the display substrate can improve the brightness uniformity of the first display area.

[0175] In some examples, such as Fig.13 As shown, 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 first sizes of the M sub-pixels 210 are equal, and the 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 the brightness uniformity of the first display area.

[0176] In some examples, such as Fig.13 As shown, 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 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.

[0177] 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 this.

[0178] In some examples, such as Fig.13 As shown, the area of ​​the second sub-pixel 212 is respectively 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.

[0179] In some examples, such as Fig.13 As shown, the shapes of the first sub-pixel 211 , the second sub-pixel 212 and the third sub-pixel 213 may be rectangular.

[0180] In other examples, Fig.13 At least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 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 embodiment of the present disclosure includes but is not limited to the above-described case, and the shape of each sub-pixel can be other shapes such as a polygon and an ellipse.

[0181] In some examples, such as Fig.13 As shown, the number of the first sub-pixels 211 , the number of the second sub-pixels 212 , and the number of the third sub-pixels 213 are the same.

[0182] Fig.14 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.14 As shown, Fig.13 The difference of the display substrate shown is that the display substrate includes at least one sub-pixel 210, and the size of the edge of the sub-pixel 210 close to the first arc-shaped edge 112A is larger than the size of the edge away from the first arc-shaped edge 112A. Therefore, the display substrate can make the area of ​​the same sub-pixel increase with the increase of the distance from the first arc-shaped edge, thereby improving the brightness uniformity of the first display area.

[0183] In some examples, such as Fig.14 As shown, the shape of the above-mentioned sub-pixel 210 (such as the second sub-pixel 212) can be an isosceles trapezoid, and the base of the isosceles trapezoid is located on the side of the top away from the first arc-shaped 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 can also be other suitable shapes.

[0184] In some examples, such as Fig.14As shown, 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.

[0185] Fig.15 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.15 As shown, the display substrate 200 includes a substrate 110 and a plurality of sub-pixels 210; the 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 the first direction, and 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 arranged equidistantly in the first direction, and the centers of two adjacent sub-pixels 210 in each sub-pixel row 220 have a first distance, that is, a pixel pitch; 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.

[0186] like Fig.15 As shown, Figure 1 and Fig.10 The display substrate shown is different in that, 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 cyclically arranged; 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.

[0187] 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 a display device with a display screen having a complex shape, thereby having a wide range of application scenarios. Moreover, in the case where the first display area has an irregular shape, by arranging a plurality of 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 plurality of 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.

[0188] In some examples, such as Fig.15As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the first side 112A is a first arc side, the second side 112B is a second arc 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 can be the extension direction of the first arc side or the second arc side; in addition, the fan-ring shape can be a shape formed by removing the acute angle of the fan.

[0189] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0190] In some examples, the base substrate 110 located in the fan-ring display area 112 can be bent along the first direction. Thus, the display substrate can also realize curved display, and because the base substrate in the fan-ring display area can be bent along the first direction, the pixel distribution and brightness of the display substrate are more uniform visually. In addition, when the base substrate in the fan-ring display area is bent along the first direction, the display substrate can form a display screen with more complex and richer shapes.

[0191] In some examples, such as Fig.15 As shown, 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 the arc direction, and each fifth spacer column 135 includes a plurality of fifth spacers 125 arranged along a direction intersecting the arc direction; in each fifth spacer column 135, the centers of the plurality of fifth spacers 125 are arranged equidistantly, and the extension directions of any two fifth spacer columns 135 intersect at the position where the first arc side 112A is away from the second arc side 112B. Therefore, the display substrate also designs the position of the spacers so that the distribution of the spacers is more reasonable, so that the mask plate can be effectively supported and protected, and the substrate to be evaporated and the mask plate can be prevented from being damaged.

[0192] In some examples, such as Fig.15 As shown, in each fifth spacer column 135, the size of the fifth spacer 135 along the arc direction increases as the distance from the first arc-shaped edge 112A increases. Thus, the display substrate can keep the area proportion of the second spacer in different regions on the display substrate consistent, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0193] In some examples, such as Fig.15 As shown, the number of the first sub-pixels 211 , the number of the second sub-pixels 212 , and the number of the third sub-pixels 213 are the same.

[0194] In some examples, such as Fig.15 As shown, the shape of the first sub-pixel 211 is a rhombus, the shape of the second sub-pixel 212 is a hexagon, and the shape of the third sub-pixel 213 is a hexagon. Of course, the embodiments of the present disclosure include but are not limited to this, and the first sub-pixel, the second sub-pixel and the third sub-pixel may also adopt other suitable shapes.

[0195] In other examples, Fig.15 At least one of the shapes of the first sub-pixel 211, the second sub-pixel 212, and the third sub-pixel 213 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 embodiment of the present disclosure includes but is not limited to the above-described case, and the shape of each sub-pixel can be other shapes such as a polygon and an ellipse.

[0196] In some examples, such as Fig.15 As shown, 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 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.

[0197] 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 this.

[0198] In some examples, such as Fig.15 As shown, the area of ​​the second sub-pixel 212 is respectively 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.

[0199] An embodiment of the present disclosure also provides another display substrate, in which the position and size of the spacers are designed. Fig.16 FIG. 1 is a partial plan view of another display substrate provided by an embodiment of the present disclosure. Fig.16As shown, 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 edge 112A and a second edge 112B arranged along a first direction, and the length of the first edge 112A is less than the length of the second edge 112B.

[0200] like Fig.16 As shown, a plurality of spacers 120 form a plurality of spacer columns 130 arranged along the extension direction of the first edge 112A or the second edge 112B, and each spacer column 130 includes a plurality of spacers 120 arranged along the first 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 of the first edge 112A away from the second edge 112B.

[0201] In the display substrate provided by the embodiment of the present disclosure, since the first display area has an irregular shape, the display substrate can be applied to a display device with a display screen of a complex shape, thus having a wide range of application scenarios. In addition, since the centers of multiple spacers in each spacer column are arranged equidistantly, the extension directions of any two spacer columns intersect at the position where the first side is far from the second side, and 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 to be evaporated and the mask plate.

[0202] It should be noted that, since 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 common rectangle or square, but an irregular shape. In addition, the center of the spacer may be a geometric center, and the geometric center may allow a certain error or range.

[0203] In some examples, such as Fig.16 As shown, 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. As a result, the display substrate can keep the area ratio of the spacers in different areas on the display substrate consistent, so as to effectively support and protect the mask plate and prevent damage to the substrate and mask plate to be evaporated. In addition, the display substrate can also better maintain the distance between the mask plate and the display substrate through the above-mentioned setting to avoid electrostatic adsorption, thereby avoiding damage to the fine metal mask plate and increasing the rigidity of the display substrate. Therefore, the display substrate also has a higher product yield.

[0204] In some examples, such as Fig.16As shown, each spacer 120 includes a first spacer edge 120A close to the first side 112A and a second spacer edge 120B close to the second side 112B, and the first spacer edge 120A and the second spacer edge 120B are arranged opposite to each other; in each spacer column 130, the first spacer edge 120A of the spacer 120 increases as the distance from the first side 112A increases, and in each spacer column 130, the second spacer edge 120B of the spacer 120 increases as the distance from the first side 112A increases. Thus, the size or area of ​​the spacer is increased by respectively increasing the size of the first spacer edge and the second spacer edge.

[0205] In some examples, such as Fig.16 As shown, for one spacer 120, the second spacer edge 120B is larger than the first spacer edge 120A. With such a configuration, the display substrate can further maintain the consistent area ratio of the spacers in different regions on the display substrate, thereby effectively supporting and protecting the mask plate and preventing damage to the substrate to be evaporated and the mask plate.

[0206] In some examples, such as Fig.16 As shown, the first display area 112 is a fan-ring display area 112 having a fan-ring shape. At this time, the above-mentioned first side 112A is a first arc-shaped side, the above-mentioned 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 above-mentioned arc direction may be the extension direction of the first arc-shaped side or the second arc-shaped side; in addition, the above-mentioned 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.

[0207] In the display substrate provided in this example, since the first display area has a fan-ring display area in a fan-ring shape, the display substrate can provide a display area in a fan-ring shape, and can even be combined with other rectangular display areas to form more types of shapes. Thus, it can be applied to display devices with display screens of different shapes, thus having a wide range of application scenarios.

[0208] There are a few points to note:

[0209] (1) In the drawings of the embodiments of the present disclosure, only the structures related to the embodiments of the present disclosure are involved, and other structures can refer to the general design.

[0210] (2) In the absence of conflict, features in the same embodiment or in different embodiments of the present disclosure may be combined with each other.
