Description

Technical Field

[0001] At least one embodiment of the present disclosure relates to a display substrate and a display device. Background Art

[0002] With people's continuous pursuit of the visual effects of display products, narrow borders and even full-screen displays have become a new trend in the development of organic light-emitting diode (OLED) display products. As the screen-to-body ratio of many mobile phones has gradually and steadily increased, full-screen has become the current trend. The front camera is the key to designing a full-screen. In order to achieve a higher screen-to-body ratio, display products with bangs screens, water drop screens, and punch-hole screens have appeared one after another. These full-screen forms have increased the screen-to-body ratio by sacrificing the appearance of the mobile phone. As a result, in recent years, under the trend of full-screen, flexible screens with integrated under-screen cameras have solved the pain points of traditional full-screen display punch-holes, and a higher screen-to-body ratio brings users a new visual experience. Summary of the invention

[0003] At least one embodiment of the present disclosure provides a display substrate and a display device.

[0004] At least one embodiment of the present disclosure provides a display substrate, including: a first display area and a second display area. At least part of the first display area is located on one side of the second display area in the first direction, the first display area includes a plurality of first light-emitting unit groups and a plurality of first pixel circuit groups connected to the plurality of first light-emitting unit groups, the second display area includes a plurality of second light-emitting unit groups and a plurality of second pixel circuit groups connected to the plurality of second light-emitting unit groups, and each light-emitting unit group includes a plurality of light-emitting units of different colors. In the first display area, a row of light-emitting units arranged along a second direction intersecting the first direction includes light-emitting units of N different colors; in the second display area, a row of light-emitting units arranged along the second direction includes light-emitting units of M different colors, N is greater than M, and both N and M are positive integers not less than 1.

[0005] For example, in the first display area, a row of light-emitting units arranged along the second direction includes light-emitting units of three different colors; in the second display area, a row of light-emitting units arranged along the second direction includes light-emitting units of one color or light-emitting units of two different colors, and the two light-emitting units of different colors are alternately arranged along the second direction.

[0006] For example, in the first display area, a row of light-emitting units arranged along the second direction includes a first-color light-emitting unit, a second-color light-emitting unit, and a third-color light-emitting unit that are repeatedly arranged in sequence; in the second display area, a row of light-emitting units arranged along the second direction includes a row of third-color light-emitting units, a row of second-color light-emitting units, or a row of first-color light-emitting units and second-color light-emitting units arranged alternately.

[0007] For example, the display substrate further includes: a third display area, the first display area is located on at least one side of the third display area, and at least a part of the second display area is located between the first display area and the third display area. The third display area includes a plurality of third light-emitting unit groups, and a plurality of third pixel circuit groups connected to the plurality of third light-emitting unit groups are located in an area outside the third display area.

[0008] For example, the plurality of first pixel circuit groups include a plurality of first pixel circuits, the plurality of second pixel circuit groups include a plurality of second pixel circuits, the density of the plurality of first pixel circuits is a first density, the density of the plurality of second pixel circuits is a second density, and the first density is not less than the second density.

[0009] For example, the density of the plurality of first light-emitting unit groups in the first display area is a third density, the density of the plurality of second light-emitting unit groups in the second display area is a fourth density, and the third density is greater than the fourth density; the density of the plurality of third light-emitting unit groups in the third display area is a fifth density, and both the third density and the fourth density are greater than the fifth density.

[0010] For example, each first light-emitting unit group, each second light-emitting unit group, and each third light-emitting unit group all include a first-color light-emitting unit, a pair of second-color light-emitting units, and a third-color light-emitting unit. The first-color light-emitting unit and the third-color light-emitting unit are located in different rows, and at least one of the pair of second-color light-emitting units is arranged along the second direction with the first-color light-emitting unit.

[0011] For example, in at least one of the second light-emitting unit groups adjacent to the first light-emitting unit group, the distance between the two light-emitting areas of the pair of second-color light-emitting units in the first direction is a first distance, and the distance between the light-emitting area of a second-color light-emitting unit in the pair of second-color light-emitting units in the at least one second light-emitting unit group that is close to the first light-emitting unit group and the light-emitting area of the second-color light-emitting unit in the first light-emitting unit group that is adjacent to and located in the first light-emitting unit group in the first direction is a second distance, and the first distance is greater than the second distance.

[0012] For example, the first distance is greater than the size of the light-emitting region of the third-color light-emitting unit in the second light-emitting unit group in the first direction.

[0013] For example, in at least one of the second light-emitting unit groups, one of the second-color light-emitting unit pairs is in the same row as the first-color light-emitting unit, and the other of the second-color light-emitting unit pairs is in the same row as the first-color light-emitting unit in the first light-emitting unit group.

[0014] For example, the ratio of the area of the light-emitting region of each first-color light-emitting unit in the third light-emitting unit group to the area of the light-emitting region of each first-color light-emitting unit in the first light-emitting unit group is 1.1 to 2.5, the ratio of the area of the light-emitting region of each second-color light-emitting unit pair in the third light-emitting unit group to the area of the light-emitting region of each second-color light-emitting unit pair in the first light-emitting unit group is 1.1 to 2.5, and the ratio of the area of the light-emitting region of each third-color light-emitting unit in the third light-emitting unit group to the area of the light-emitting region of each third-color light-emitting unit in the first light-emitting unit group is 1.1 to 2.5.

[0015] For example, the plurality of second light-emitting unit groups include a first sub-light-emitting unit group and a second sub-light-emitting unit group that are alternately arranged along the second direction, and at least one third light-emitting unit group adjacent to the plurality of second light-emitting unit groups is in the same column as the second sub-light-emitting unit group; in at least one of the first light-emitting unit groups, the distance between the light-emitting region of the first-color light-emitting unit and the light-emitting region of the second-color light-emitting unit adjacent thereto is a third distance; in at least one of the first sub-light-emitting unit groups, the distance between the light-emitting region of the first-color light-emitting unit and the light-emitting region of the second-color light-emitting unit adjacent thereto is a fourth distance; in at least one of the second sub-light-emitting unit groups, the distance between the light-emitting region of the first-color light-emitting unit and the light-emitting region of the second-color light-emitting unit adjacent thereto is a fifth distance, the fifth distance is greater than the fourth distance, and the fourth distance is greater than the third distance.

[0016] For example, in the first sub-light-emitting unit group, the distance between the two centerlines extending along the first direction in the two light-emitting regions of at least one of the second-color light-emitting unit pairs is a sixth distance; in at least one of the second sub-light-emitting unit groups, the distance between the two centerlines extending along the first direction in the two light-emitting regions of the second-color light-emitting unit pair is a seventh distance, and the seventh distance is greater than the sixth distance.

[0017] For example, in the first sub-light-emitting unit group, the distance between the center line extending along the first direction in the light-emitting area of at least one first-color light-emitting unit and the center line extending along the first direction in the light-emitting area of the second-color light-emitting unit in a different row from the first-color light-emitting unit is the eighth distance; in at least one second sub-light-emitting unit group, the distance between the center line extending along the first direction in the light-emitting area of the first-color light-emitting unit and the center line extending along the first direction in the light-emitting area of the second-color light-emitting unit in a different row from the first-color light-emitting unit is the ninth distance, and the ratio of the ninth distance to the eighth distance is 0.8 to 1.2.

[0018] For example, in at least one first light-emitting unit group and at least one second light-emitting unit group, the shapes of the light-emitting areas of the first-color light-emitting units are substantially the same and the areas are substantially equal; in the first light-emitting unit group and the second light-emitting unit group, the shapes of the light-emitting areas of the third-color light-emitting units are substantially the same and the areas are substantially equal.

[0019] For example, in at least one first light-emitting unit group, the shapes of the light-emitting areas of the first-color light-emitting units and the third-color light-emitting units include hexagons, and the shapes of the light-emitting areas of the second-color light-emitting units in each pair of second-color light-emitting units include pentagons.

[0020] For example, in at least one first light-emitting unit group and at least one third light-emitting unit group, the shapes of the light-emitting areas of the light-emitting units emitting the same color light are different; in at least one third light-emitting unit group, the shape of the light-emitting area of at least one light-emitting unit includes a circle, an ellipse or a water droplet shape.

[0021] For example, the ratio of the area of the light-emitting area of each first-color light-emitting unit in the third light-emitting unit group to the area of the light-emitting area of each first-color light-emitting unit in the first light-emitting unit group is 0.5 to 1, the ratio of the area of the light-emitting area of each pair of second-color light-emitting units in the third light-emitting unit group to the area of the light-emitting area of each pair of second-color light-emitting units in the first light-emitting unit group is 0.5 to 1, and the ratio of the area of the light-emitting area of each third-color light-emitting unit in the third light-emitting unit group to the area of the light-emitting area of each third-color light-emitting unit in the first light-emitting unit group is 0.5 to 1.

[0022] For example, in at least one second light-emitting unit group and at least one third light-emitting unit group, the shapes of the light-emitting areas of the light-emitting units emitting the same color light are substantially the same and the areas are substantially equal; in at least one first light-emitting unit group and at least one third light-emitting unit group, the shapes of the light-emitting areas of the light-emitting units emitting the same color light are different.

[0023] For example, in at least one of the second pixel circuit groups, the second pixel circuit includes two sub-pixel circuits, and the two sub-pixel circuits are configured to be connected to the same light-emitting unit; in the first pixel circuit group, the first pixel circuit includes one sub-pixel circuit, and different sub-pixel circuits are configured to be connected to different light-emitting units.

[0024] For example, the display substrate further includes: a plurality of data lines extending along the first direction. The plurality of data lines includes first sub-data lines and second sub-data lines; the first display area includes a first pixel circuit column, the second display area includes a second pixel circuit column, and the first pixel circuit column and the second pixel circuit column are in different columns; the first sub-data lines are connected to the first pixel circuit column, the second sub-data lines are connected to the second pixel circuit column, the first sub-data lines and the second sub-data lines are connected through a data line connection portion, the extending direction of the data line connection portion intersects with the first direction, and the data line connection portion and the data lines are in different layers.

[0025] For example, the first display area further includes a third pixel circuit column, the second display area further includes a fourth pixel circuit column, and at least a part of the third pixel circuit column and the fourth pixel circuit column are in the same column; the plurality of data lines further includes third sub-data lines and fourth sub-data lines, the third sub-data lines are connected to the third pixel circuit column, the fourth sub-data lines are connected to the fourth pixel circuit column, and the third sub-data lines and the fourth sub-data lines are a continuous data line extending along the first direction.

[0026] For example, the display substrate further includes: a plurality of power signal lines extending along the first direction. The plurality of power signal lines includes a plurality of first sub-power signal lines and a plurality of second sub-power signal lines, the plurality of first sub-power signal lines are connected to the plurality of first pixel circuit groups, the plurality of second sub-power signal lines are connected to the plurality of second pixel circuit groups, and the first sub-power signal lines are configured to transmit a first power signal, and the second sub-power signal lines are configured to transmit a second power signal.

[0027] For example, among the plurality of second sub-power signal lines, there are second sub-power signal lines that are in the same straight line as at least one of the first sub-power signal lines, and there is a gap between the first sub-power signal lines and the second sub-power signal lines that are in the same straight line.

[0028] For example, the display substrate further includes: a substrate substrate; a light-shielding layer located on the substrate substrate and at the edge of the third display region, and a positive projection of the light-shielding layer on the substrate substrate overlaps with positive projections of the second sub-data lines and the fourth sub-data lines on the substrate substrate. The light-shielding layer is located on a side of the film layer where the data line connection portion is located away from the film layer where the power signal line is located, and at least one of the plurality of second sub-power signal lines is connected to the light-shielding layer.

[0029] For example, each pixel circuit group among the plurality of first pixel circuit groups, the plurality of second pixel circuit groups, and the plurality of third pixel circuit groups includes a plurality of thin film transistors. The display substrate includes a substrate substrate and an active semiconductor layer provided on the substrate substrate. The active semiconductor layer includes active layer patterns and doping region patterns of the respective thin film transistors, and the active semiconductor layer further includes dummy patterns; the display substrate further includes an insulating layer on a side of the active semiconductor layer away from the substrate substrate, and a source-drain metal layer on a side of the insulating layer away from the active semiconductor layer. The insulating layer includes a first via hole and a second via hole. The source-drain metal layer is connected to the doping region pattern through the first via hole, and the second via hole is configured to expose the dummy pattern.

[0030] At least one embodiment of the present disclosure provides a display device including the above display substrate. Description of the Drawings

[0048] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0049] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The terms "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or items appearing before the term cover the elements or items listed after the term and their equivalents, without excluding other elements or items.

[0050] An under-screen camera refers to a front camera located under the screen without affecting the screen display function. When the front camera is not in use, the screen above the camera can still display images normally. From the appearance, there will be no camera hole for the under-screen camera, truly achieving a full-screen display effect.

[0051] In the research, the inventors of the present application found that: currently, in an organic light-emitting diode display device with an under-screen camera design, there are a low-density display area (L area) and a high-density display area (H area). The display brightness and current of the L area are at least half lower than those of the H area, which will affect the display effect. For example, the pixel luminous density of the L area is 1 / 8 to 1 / 2 of that of the H area, and the boundary between the L area and the H area appears dark. The L area is a light-transmissive display area, and the H area is an opaque display area only for display. The L area includes light-emitting units, and the pixel circuits for driving the light-emitting units in the L area are located in areas outside the L area to improve the light transmittance of the L area, that is, the light transmittance of the L area is improved by separating the light-emitting units and the pixel circuits. For example, the L area can be a hole area in the entire display area where no pixel circuits are provided.

[0052] Embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes a first display area and a second display area. At least part of the first display area is located on one side of the second display area in a first direction. The first display area includes a plurality of first light-emitting unit groups and a plurality of first pixel circuit groups connected to the plurality of first light-emitting unit groups. The second display area includes a plurality of second light-emitting unit groups and a plurality of second pixel circuit groups connected to the plurality of second light-emitting unit groups. Each light-emitting unit group includes a plurality of light-emitting units of different colors. In the first display area, a row of light-emitting units arranged along a second direction intersecting the first direction includes N light-emitting units of different colors; in the second display area, a row of light-emitting units arranged along the second direction includes M light-emitting units of different colors, where N is greater than M, and both N and M are positive integers not less than 1. In the embodiments of the present disclosure, by setting the number of light-emitting units of different colors in a row of light-emitting units in the first display area to be different from the number of light-emitting units of different colors in a row of light-emitting units in the second display area, it is beneficial to adjust the display effect of the display substrate.

[0053] The following describes the display substrate and the display device provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0054] Figure 1 FIG. is a partial plan structure diagram of a display substrate provided according to an embodiment of the present disclosure, Figure 2 For Figure 1 FIG. shows a partial view of the light-emitting units at the boundary position between the first display area and the second display area. As Figure 1 and Figure 2 shown, the display substrate includes a first display area 10 and a second display area 20, and at least part of the first display area 10 is located on one side of the second display area 20 in a first direction. For example, Figure 1 in FIG., the Y direction shown is the first direction, and the first display area 10 is located on one side of the second display area 20 in the Y direction. Figure 1 Only the shapes, sizes, and positional relationships of the first display area and the second display area are schematically shown. In an actual product, the shapes of the respective display areas can be regular shapes or irregular shapes; for example, the second display area may include a protruding area, the first display area includes a recessed area, the protruding area of the second display area can be inserted into the recessed area of the first display area, and the protruding area of the second display area can have a complementary shape to the recessed area of the first display area. For example, the side of the second display area away from the first display area may also include a recessed area.

[0055] As Figure 1 and Figure 2As shown, the first display area 10 includes a plurality of first light-emitting unit groups 100 and a plurality of first pixel circuit groups 200 connected to the plurality of first light-emitting unit groups 100, and the second display area 20 includes a plurality of second light-emitting unit groups 300 and a plurality of second pixel circuit groups 400 connected to the plurality of second light-emitting unit groups 300. For example, the plurality of first pixel circuit groups 200 are connected to the plurality of first light-emitting unit groups 100 in a one-to-one correspondence. For example, the plurality of second pixel circuit groups 400 are connected to the plurality of second light-emitting unit groups 300 in a one-to-one correspondence.

[0056] For example, as Figure 1 shown, the display substrate includes a substrate 01, and the first light-emitting unit groups 100, the first pixel circuit groups 200, the second light-emitting unit groups 300, and the second pixel circuit groups 400 are all located on the substrate 01. In the figure, it is schematically shown that the orthographic projection of the first light-emitting unit group 100 and the first pixel circuit group 200 connected thereto on the substrate 01 overlaps, and the orthographic projection of the second light-emitting unit group 300 and the second pixel circuit group 400 connected thereto on the substrate 01 overlaps, but it is not limited thereto, and the light-emitting unit group and the pixel circuit group connected thereto may also not overlap.

[0057] As Figure 1 and Figure 2 shown, each light-emitting unit group includes a plurality of light-emitting units 120 of different colors. The light-emitting units of different colors here refer to light-emitting units that emit light of different colors. For example, each light-emitting unit group may include at least one of a light-emitting unit that emits red light, a light-emitting unit that emits green light, and a light-emitting unit that emits blue light. The above-mentioned light-emitting units refer to light-emitting elements (such as organic light-emitting elements), including a first electrode, a second electrode, and a light-emitting layer located between the first electrode and the second electrode, and the first electrode, the light-emitting layer, and the second electrode are sequentially stacked in a direction perpendicular to the substrate. Figure 2 Schematically shows the second electrode of each light-emitting unit. For example, the second electrode of each light-emitting unit includes a main electrode and a connecting electrode. The shape of the main electrode is substantially the same as the shape of the light-emitting area (described later) of each light-emitting unit, and the connecting electrode is configured to be connected to the pixel circuit, for example, connected to a thin-film transistor included in the pixel circuit. For example, as Figure 2 shown, the main electrode 0121 of the first-color light-emitting unit 121 in the first display area 10 is generally hexagonal in shape, and the edge of the main electrode 0121 surrounds the light-emitting area, and the connecting electrode 0122 is the part of the second electrode other than the main electrode 0121 and is used to connect to the pixel circuit.

[0058] As Figure 1 and Figure 2As shown, in the first display area 10, a row of light-emitting units 120 arranged along a second direction intersecting the first direction includes light-emitting units of N different colors; in the second display area 20, a row of light-emitting units 120 arranged along the second direction includes light-emitting units of M different colors, where N is greater than M, and both N and M are positive integers not less than 1. The X direction shown in the figure is the second direction. For example, the first direction and the second direction can be perpendicular, but this is not limited thereto. For example, the first direction and the second direction can be interchanged. For example, in the embodiments of the present disclosure, the second direction is taken as the row direction as an example for description. For example, the first direction can be the column direction, and the light-emitting units arranged along the second direction are a row of light-emitting units arranged along the row direction. The embodiments of the present disclosure are not limited thereto, and the row direction and the column direction can be interchanged.

[0059] For example, as Figure 2 shown, in the first display area 10, a row of light-emitting units 120 arranged along the second direction includes three light-emitting units 121, 122, and 123 of different colors; in the second display area 20, a row of light-emitting units 120 arranged along the second direction includes a light-emitting unit of one color or two light-emitting units of different colors, and the two light-emitting units of different colors are alternately arranged along the second direction. For example, N can be 3, and M can be 1 or 2. The embodiments of the present disclosure are not limited thereto. A row of light-emitting units arranged along the second direction in the first display area can also include four light-emitting units of different colors, or two light-emitting units of different colors.

[0060] For example, as Figure 1 and Figure 2 shown, each first light-emitting unit group 100 and each second light-emitting unit group 300 each include a first-color light-emitting unit 121, a pair of second-color light-emitting units 122, and a third-color light-emitting unit 123. The first-color light-emitting unit 121 and the third-color light-emitting unit 123 are located in different rows, and at least one of the pair of second-color light-emitting units 122 is arranged along the second direction with the first-color light-emitting unit 121.

[0061] For example, as Figure 2 shown, in the first display area 10, a row of light-emitting units 120 arranged along the second direction includes a first-color light-emitting unit 121, a second-color light-emitting unit 1221, and a third-color light-emitting unit 123 arranged in repeated sequence; in the second display area 20, a row of light-emitting units 120 arranged along the second direction includes a row of third-color light-emitting units 123, a row of second-color light-emitting units 1222, or a row of alternately arranged first-color light-emitting units 121 and second-color light-emitting units 1221.

[0062] For example, as Figure 2As shown, in the first display area 10, a row of light-emitting units 120 arranged in the second direction may include a first-color light-emitting unit 121, a second-color light-emitting unit 1221, and a third-color light-emitting unit 123, or may include a first-color light-emitting unit 121, a second-color light-emitting unit 1222, and a third-color light-emitting unit 123. The second-color light-emitting unit 1221 and the second-color light-emitting unit 1222 may be arranged in the first direction.

[0063] An embodiment of the present disclosure schematically shows that the first-color light-emitting unit may be a red light-emitting unit, the second-color light-emitting unit may be a green light-emitting unit, and the third-color light-emitting unit may be a blue light-emitting unit. However, it is not limited thereto. The first-color light-emitting unit may be a blue light-emitting unit, and the third-color light-emitting unit may be a red light-emitting unit.

[0064] For example, as Figure 1 and Figure 2 shown, at least one second light-emitting unit group 300 in the second display area 20 may include three rows of light-emitting units. The three rows of light-emitting units may include a row of third-color light-emitting units 123, a row of second-color light-emitting units 1222, and a row of alternately arranged first-color light-emitting units 121 and second-color light-emitting units 1221.

[0065] For example, as Figure 2 shown, a protruding area is provided on one side of the second display area 20 close to the first display area 10, and a recessed area is provided on one side of the first display area 10 close to the second display area 20. The protruding area of the second display area 20 may be inserted into the recessed area of the first display area 10. A row of second-color light-emitting units 1222 in the second display area 20 may be located in the protruding area of the second display area 20, that is, in the recessed area of the first display area 10. Then, a row of second-color light-emitting units 1222 in the second display area 20 may be in the same row as the light-emitting units in the first display area 10. Here, "a row of second-color light-emitting units 1222 in the second display area 20 may be in the same row as the light-emitting units in the first display area 10" means that a straight line extending parallel to the row direction may pass through the second-color light-emitting units 1222 and the light-emitting units in the first display area 10.

[0066] For example, as Figure 2As shown, in the first display area 10, the two second-color light-emitting units 1221 and 1222 included in the second-color light-emitting unit pair 122 are arranged along the first direction. The second-color light-emitting unit 1222 in the second display area 20 can be arranged substantially along the first direction with the second-color light-emitting unit pair 122 in the first display area 10, while the second-color light-emitting unit 1221 in the second display area 20 can be arranged substantially along the first direction with the second-color light-emitting unit pair 122 in the first display area 10, or can be offset by a certain distance from the second-color light-emitting unit pair 122 in the first display area 10 in the second direction. The above-mentioned "two second-color light-emitting units 1221 and 1222" can be respectively referred to as the first light-emitting unit block 1221 and the second light-emitting unit block 1222.

[0067] For example, each light-emitting unit includes a light-emitting area. Here, the "light-emitting area" can refer to a two-dimensional planar area that is parallel to the substrate. For example, the display substrate further includes a pixel defining layer located on the substrate. The pixel defining layer includes an opening for defining the light-emitting area of the light-emitting unit. The opening exposes the second electrode of the light-emitting unit. When at least a part of the light-emitting layer of the subsequent light-emitting unit is formed in the opening of the pixel defining layer, the light-emitting layer located in the opening contacts the second electrode, so that this part can drive the light-emitting layer to emit light to form a light-emitting area. It should be noted that due to process reasons, the size of the part of the opening of the pixel defining layer away from the substrate is slightly larger than the size of the part close to the substrate, or shows a gradually increasing size form from the side close to the substrate to the side away from the substrate. Therefore, the size of the light-emitting area may be slightly different from the size of different positions of the opening of the pixel defining layer, but the overall area shape and size are basically the same. For example, the orthographic projection of the light-emitting area on the substrate substantially coincides with the orthographic projection of the corresponding opening of the pixel defining layer on the substrate. For example, the orthographic projection of the light-emitting area on the substrate completely falls within the orthographic projection of the corresponding opening of the pixel defining layer on the substrate, and the two have similar shapes. The projected area of the light-emitting area on the substrate is slightly smaller than the projected area of the corresponding opening of the pixel defining layer on the substrate.

[0068] For example, as Figure 1 and Figure 2 shown, in at least one second light-emitting unit group 300 adjacent to the first light-emitting unit group 100, the two light-emitting areas of the second-color light-emitting unit pair 122 ( Figure 2The distance of the dashed box shown in the first direction is the first distance D1. In this embodiment, the distance between the edges of the two light-emitting regions close to each other in the first direction is schematically shown, or in the first direction, the distance between the two points closest to each other in the two light-emitting regions. However, it is not limited to this. The above first distance may also refer to the distance between the centers of the two light-emitting regions in the first direction, that is, the distance between two straight lines extending along the second direction (the second direction is perpendicular to the first direction) passing through the centers of the two light-emitting regions respectively. The distance between the light-emitting region of the second light-emitting unit block 1222 in the second-color light-emitting unit pair 122 of the second light-emitting unit group 300 adjacent to the first light-emitting unit group 100 and the light-emitting region of the first light-emitting unit block 1221 adjacent to the light-emitting region and located in the first light-emitting unit group 100 in the first direction is the second distance D2. In this embodiment, the distance between the edges of the two light-emitting regions close to each other in the first direction is schematically shown. However, it is not limited to this. The above second distance may also refer to the distance between the centers of the two light-emitting regions in the first direction, that is, the distance between two straight lines extending along the second direction (the second direction is perpendicular to the first direction) passing through the centers of the two light-emitting regions respectively. The first distance D1 is greater than the second distance D2.

[0069] It should be noted that the above first distance and second distance are both under the same definition, that is, they can both be the distance between the edges of the two light-emitting regions close to each other in the first direction, or the distance between the centers of the two light-emitting regions in the first direction, etc.

[0070] For example, as Figure 2 shown, the second light-emitting unit block 1222 in the second light-emitting unit group and the light-emitting unit 120 in the first light-emitting unit group are in the same row. The second light-emitting unit block 1222 is closer to the first light-emitting unit block 1221 in the first light-emitting unit group than the first light-emitting unit block 1221 in the same second light-emitting unit group.

[0071] For example, as Figure 2 shown, the first distance D1 is greater than the size of the light-emitting region of the third-color light-emitting unit 123 in the second light-emitting unit group 300 in the first direction. For example, as Figure 2 shown, in the second light-emitting unit group 300, the third-color light-emitting unit 123 may be located between the two second-color light-emitting units 1221 and 1222.

[0072] For example, as Figure 2 shown, the second distance D2 is less than the size of the light-emitting region of the third-color light-emitting unit 123 in the second light-emitting unit group in the first direction. For example, as Figure 2As shown, the second distance D2 is smaller than the size of the light-emitting region of the third-color light-emitting unit 123 in the first light-emitting unit group in the first direction. For example, the size of the light-emitting region of the third-color light-emitting unit 123 in the first light-emitting unit group in the first direction may be substantially equal to the size of the light-emitting region of the third-color light-emitting unit 123 in the second light-emitting unit group in the first direction. "Substantially equal" in the present disclosure means that the ratio of the difference between the two to one of them is not greater than 0.2.

[0073] For example, as Figure 1 and Figure 2 shown, in each second light-emitting unit group 300, one of the second-color light-emitting unit pairs 122 is in the same row as the first-color light-emitting unit 121. For example, the first light-emitting unit block 1221 is in the same row as the first-color light-emitting unit 121. For example, as Figure 1 and Figure 2 shown, in the second light-emitting unit group 300 adjacent to the first light-emitting unit group 100, the other second-color light-emitting unit of the second-color light-emitting unit pair 122 is in the same row as the first-color light-emitting unit 121 and the third-color light-emitting unit 123 in the first light-emitting unit group 100. For example, the second light-emitting unit block 1222 in the second light-emitting unit group 300 is in the same row as the first-color light-emitting unit 121 and the third-color light-emitting unit 123 in the first light-emitting unit group 100.

[0074] The embodiments of the present disclosure only schematically show one row of second light-emitting unit groups adjacent to the first light-emitting unit group. The embodiments of the present disclosure are not limited to only including this row of second light-emitting unit groups. For example, the second display area may include multiple rows of second light-emitting unit groups. In other second light-emitting unit groups except the second light-emitting unit groups adjacent to the first light-emitting unit group, one of the second-color light-emitting unit pairs 122 is in the same row as the first-color light-emitting unit 121, and the other second-color light-emitting unit of the second-color light-emitting unit pair 122 is in the same row as the first-color light-emitting unit 121 and the third-color light-emitting unit 123 in another second light-emitting unit group (this second light-emitting unit group is the second light-emitting unit group adjacent to the above-mentioned "other second light-emitting unit groups" in the first direction).

[0075] For example, as Figure 1 and Figure 2 shown, the number of light-emitting units in one row arranged along the second direction in the first display area 10 is greater than the number of light-emitting units in one row arranged along the second direction in the second display area 20. For example, as Figure 1 and Figure 2 shown, the average distance between the light-emitting regions of two adjacent light-emitting units in the same row in the first display area 10 is a, and the average distance between the light-emitting regions of two adjacent light-emitting units in any row in the second display area 20 is b, and a is less than b.

[0076] For example, as Figure 1 and 2 shown, the density of the multiple first light-emitting unit groups 100 in the first display area 10 is the third density, and the density of the multiple second light-emitting unit groups 300 in the second display area 20 is the fourth density, and the third density is greater than the fourth density. In the embodiments of the present disclosure, "the third density is greater than the fourth density" may mean that the number of the first light-emitting unit groups is greater than the number of the second light-emitting unit groups under the same area. For example, the above-mentioned same area may be the area of a rectangle, the long side of the rectangle is parallel to the second direction, and the short side is parallel to the first direction. For example, the number of a row of the second light-emitting unit groups may be q, and the long side of the above-mentioned rectangle may be the length of p (p is a positive integer not greater than q) second light-emitting unit groups along the first direction, and the short side of the rectangle may be the length of one second light-emitting unit group along the second direction. The embodiments of the present disclosure are not limited thereto.

[0077] For example, Figure 3 is a partial plan view of a display substrate according to an embodiment of the present disclosure, Figure 4 is Figure 3 a partial view of the light-emitting units at the junction position of the first display area, the second display area, and the third display area in an example of the shown display substrate. As Figure 3 and Figure 4 shown, the display substrate further includes a third display area 30, the first display area 10 is located on at least one side of the third display area 30, and at least a part of the second display area 20 is located between the first display area 10 and the third display area 30. For example, as Figure 3 shown, the first display area 10 may surround the third display area 30. For example, the first display area 10 may be located on both sides of the third display area 30 in the X direction and on at least one side in the Y direction. For example, as Figure 3 shown, the first display area 10 surrounds the second display area 20. For example, the first display area 10 includes parts located on both sides of the second display area 20 in the X direction and on at least one side in the Y direction. The embodiments of the present disclosure schematically show that the position of the third display area is at the middle of the top of the overall display area (the complete area for display in the display substrate, such as including the first display area, the second display area, and the third display area, etc.), but it is not limited thereto and can be set according to actual needs. For example, it can also be located at the upper left corner or the upper right corner of the overall display area, etc. Figure 3 Schematically shown, the shapes of the second display area and the third display area are both rectangles, but it is not limited thereto. The shape of at least one of the above-mentioned second display area and the third display area may also be a regular shape such as a circle or an ellipse or an irregular shape. The embodiments of the present disclosure do not limit this.

[0078] For example, as Figure 3 and Figure 4As shown, the third display area 30 includes a plurality of third light-emitting unit groups 500, and a plurality of third pixel circuit groups 600 connected to the plurality of third light-emitting unit groups 500 are located in areas outside the third display area 30. For example, the plurality of third pixel circuit groups 600 are connected to the plurality of third light-emitting unit groups 500 in a one-to-one correspondence. By arranging the third pixel circuit groups for driving the third light-emitting unit groups in the third display area to emit light in areas outside the third display area, the light transmittance of the third display area can be increased, that is, the light transmittance of the third display area is increased by separating the light-emitting units and the pixel circuits. For example, the third display area is an area for arranging an under-screen camera. Of course, in the embodiments of the present disclosure, it is not limited to arranging a front camera module on the side of the substrate away from the light-emitting units in the third display area, and it can also be other functional components such as a 3D structured light module (for example, a 3D structured light sensor), a time-of-flight 3D imaging module (for example, a time-of-flight sensor), and an infrared sensing module (for example, an infrared sensing sensor).

[0079] For example, as Figure 3 shown, the display substrate further includes a transition area 40 located between the first display area 10 and the third display area 30. The transition area 40 includes two parts located on both sides of the third display area 30 in the X direction. The transition area 40 includes a plurality of fourth light-emitting unit groups 700 and a plurality of fourth pixel circuit groups 800 connected to the plurality of fourth light-emitting unit groups 700. For example, the plurality of fourth pixel circuit groups 800 are connected to the plurality of fourth light-emitting unit groups 700 in a one-to-one correspondence. For example, the transition area 40 further includes a third pixel circuit group 600 connected to the third light-emitting unit group 500. In the embodiments of the present disclosure, each light-emitting unit and the pixel circuit connected thereto form a sub-pixel, that is, the display substrate includes a plurality of sub-pixels, and each sub-pixel includes a light-emitting unit and the pixel circuit connected thereto.

[0080] For example, as Figure 3 and Figure 4As shown, the density of multiple third light-emitting unit groups 500 in the third display area 30 is the fifth density. The density of multiple first light-emitting unit groups 100 (i.e., the third density) in the first display area 10 and the density of multiple second light-emitting unit groups 300 (i.e., the fourth density) in the second display area 20 are both greater than the fifth density. The third density is greater than the fourth density, and the fourth density is greater than the fifth density. In the embodiments of the present disclosure, the number of first light-emitting unit groups and the number of second light-emitting unit groups are both greater than the number of third light-emitting unit groups under the same area. In the embodiments of the present disclosure, the density of the first light-emitting unit groups in the first display area is greater than the density of the third light-emitting unit groups in the third display area. By providing the second display area between the third display area and the first display area, and the density of the light-emitting unit groups in the second display area is between the density of the light-emitting unit groups in the first display area and the third display area, the boundary where the first display area and the third display area are close to each other can be made brighter. Compared with the case where the first display area and the third display area are adjacent (i.e., there is no second display area between the two), the display substrate provided by the embodiments of the present disclosure is beneficial to improving the cyan or dark phenomenon at the boundary where the third display area and the first display area are close to each other, and thus improving the display image quality of the third display area (the area where the under-screen camera is located).

[0081] For example, the ratio of the fifth density to the third density can be 0.1 to 0.5, and the ratio of the fourth density to the third density can be 0.5 to 0.9. For example, the ratio of the fifth density to the third density can be 1 / 4, and the ratio of the fourth density to the third density can be 1 / 2.

[0082] For example, as Figure 3 and Figure 4 shown, in the third display area 30, a row of light-emitting units arranged along the second direction includes light-emitting units of one color or light-emitting units of two different colors, and the two different color light-emitting units are alternately arranged along the second direction.

[0083] For example, as Figure 3 and Figure 4 shown, the third light-emitting unit group 500 includes a first color light-emitting unit 121, a pair of second color light-emitting units 122 (including a first light-emitting unit block 1221 and a second light-emitting unit block 1222), and a third color light-emitting unit 123. The first color light-emitting unit 121 and the third color light-emitting unit 123 are located in different rows, and at least one of the pair of second color light-emitting units 122 is arranged along the second direction with the first color light-emitting unit 121.

[0084] For example, as Figure 3 and Figure 4As shown, in the third display area 30, a row of light-emitting units 120 arranged along the second direction includes a row of third-color light-emitting units 123, a row of second light-emitting unit blocks 1222, or a row of first-color light-emitting units 121 and first light-emitting unit blocks 1221 arranged alternately. For example, at least one light-emitting unit group 500 in the third display area 30 may include three rows of light-emitting units, and the three rows of light-emitting units may include a row of third-color light-emitting units 123, a row of second light-emitting unit blocks 1222, and a row of first-color light-emitting units 121 and first light-emitting unit blocks 1221 arranged alternately.

[0085] For example, as Figure 3 and Figure 4 shown, the arrangement rule of light-emitting units of different colors in the second light-emitting unit group 300 may be the same as that of light-emitting units of different colors in the third light-emitting unit group 500.

[0086] For example, as Figure 3 and Figure 4 shown, a protruding area is provided on one side of the third display area 30 close to the second display area 20, and a recessed area is provided on one side of the second display area 20 close to the third display area 30. The protruding area of the third display area 30 can be inserted into the recessed area of the second display area 20. A row of second light-emitting unit blocks 1222 in the third display area 30 can be located in the protruding area of the third display area 30, that is, in the recessed area of the second display area 20. Then, a row of second light-emitting unit blocks 1222 in the third display area 30 can be in the same row as the light-emitting units in the second display area 20.

[0087] For example, as Figure 3 and Figure 4 shown, in the third display area 30, the first light-emitting unit blocks 1221 and the second light-emitting unit blocks 1222 included in the second-color light-emitting unit pair 122 are arranged along the first direction, and some of the first light-emitting unit blocks 1221 in the second display area 20 can be arranged substantially along the first direction with the second light-emitting unit blocks 1222 in the third display area 30.

[0088] For example, as Figure 3 and Figure 4 shown, each light-emitting unit in the third light-emitting unit group includes a light-emitting area, and the light-emitting area can have the same definition as the light-emitting areas of the light-emitting units in Figure 2 the first light-emitting unit group and the second light-emitting unit group shown. Figure 4 The light-emitting area (dotted line frame) of the third light-emitting unit group is shown.

[0089] For example, as Figure 3 and Figure 4As shown, multiple third light-emitting unit groups 500 are arranged in multiple rows of third light-emitting unit groups 500, and adjacent rows of third light-emitting unit groups 500 are staggered in the row direction. Multiple second light-emitting unit groups 300 are arranged in at least one row of second light-emitting unit groups 300. For example, the second light-emitting unit groups 300 are arranged in one row of second light-emitting unit groups 300.

[0090] For example, as Figure 3 and Figure 4 shown, the third light-emitting unit groups 500 in one of the odd rows and even rows are in the same column as the odd-numbered second light-emitting unit groups 300, and the third light-emitting unit groups 500 in the other of the odd rows and even rows are in the same column as the even-numbered second light-emitting unit groups 300. In the embodiments of the present disclosure, the second light-emitting unit group and the third light-emitting unit group in the same column refer to the second light-emitting unit group and the third light-emitting unit group when the first light-emitting unit block in the second light-emitting unit group and the second light-emitting unit block in the third light-emitting unit group are in the same column (i.e., arranged in the column direction).

[0091] For example, as Figure 3 and Figure 4 shown, multiple first light-emitting unit groups 100 include multiple columns of third sub-light-emitting unit groups 1100 and multiple columns of fourth sub-light-emitting unit groups 1200, and the multiple columns of third sub-light-emitting unit groups 1100 and the multiple columns of fourth sub-light-emitting unit groups 1200 are alternately arranged in the row direction. For example, the first-color light-emitting unit 121, the third-color light-emitting unit 123, and at least one second-color light-emitting unit in the second light-emitting unit group 300 are in the same column as the third sub-light-emitting unit group 1100. The above “the first-color light-emitting unit 121, the third-color light-emitting unit 123, and at least one second-color light-emitting unit in the second light-emitting unit group 300 are in the same column as the third sub-light-emitting unit group 1100” may mean that the first-color light-emitting unit in the second light-emitting unit group and the first-color light-emitting unit in the third sub-light-emitting unit group are arranged substantially in the column direction, the third-color light-emitting unit in the second light-emitting unit group and the third-color light-emitting unit in the third sub-light-emitting unit group are arranged substantially in the column direction, and the second light-emitting unit block in the second light-emitting unit group and the first light-emitting unit block in the third sub-light-emitting unit group are arranged substantially in the column direction.

[0092] For example, as Figure 3 and Figure 4As shown, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 is greater than 1. For example, the ratio of the area of the light-emitting region of each first-color light-emitting unit 121 in the third light-emitting unit group 500 to the area of the light-emitting region of each first-color light-emitting unit 121 in the first light-emitting unit group 100 is 1.1 to 2.5. The ratio of the area of the light-emitting region of each second-color light-emitting unit pair 122 in the third light-emitting unit group 500 to the area of the light-emitting region of each second-color light-emitting unit pair 122 in the first light-emitting unit group 100 is 1.1 to 2.5. The ratio of the area of the light-emitting region of each third-color light-emitting unit 123 in the third light-emitting unit group 500 to the area of the light-emitting region of each third-color light-emitting unit 123 in the first light-emitting unit group 100 is 1.1 to 2.5.

[0093] For example, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 can be 1.3 to 2.2. For example, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 can be 1.5 to 2. For example, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 can be 1.8.

[0094] In the research, the inventors of the present application also found that: when a second display area is provided between the first display area and the third display area, and the area of the light-emitting region of each light-emitting unit in the third display area is relatively large, in the second light-emitting unit group and the third light-emitting unit group that are adjacent and in the same column, the light-emitting layer of the second-color light-emitting unit in the second light-emitting unit group is likely to overlap with the light-emitting layer of the third-color light-emitting unit in the third light-emitting unit group. To solve the above situation, the second-color light-emitting units in the same row in the second display area can be arranged with unequal intervals.

[0095] For example, as Figure 3 and Figure 4 shown, the multiple second light-emitting unit groups 300 include a first sub-light-emitting unit group 310 and a second sub-light-emitting unit group 320 that are alternately arranged in the second direction. At least one third light-emitting unit group 500 in the row of third light-emitting unit groups 500 adjacent to the multiple second light-emitting unit groups 320 among the multiple third light-emitting unit groups 500 is in the same column as the second sub-light-emitting unit group 320. For example, the third light-emitting unit group 500 adjacent to the second light-emitting unit group 320 is in the same column as the second light-emitting unit group 320. For example, the second light-emitting unit block 1222 in the third light-emitting unit group 500 adjacent to the second light-emitting unit group 300 is in the same row as the first-color light-emitting unit 121 in the second light-emitting unit group 300.

[0096] For example, as Figure 3 andFigure 4 As shown, in at least one first light-emitting unit group 100, the distance between the light-emitting region of the first-color light-emitting unit 121 and the light-emitting region of the first light-emitting unit block 1221 is the third distance D3; in at least one first sub-light-emitting unit group 310, the distance between the light-emitting region of the first-color light-emitting unit 121 and the light-emitting region of the first light-emitting unit block 1221 is the fourth distance D4; in at least one second sub-light-emitting unit group 320, the distance between the light-emitting region of the first-color light-emitting unit 121 and the light-emitting region of the first light-emitting unit block 1221 is the fifth distance D5, the fifth distance D5 is greater than the fourth distance D4, and the fourth distance D4 is greater than the third distance D3. For example, the fifth distance D5 can be 50 to 60 micrometers, the fourth distance can be 28 to 35 micrometers, and the third distance D3 can be 20 to 27 micrometers.

[0097] In the embodiments of the present disclosure, it is schematically shown that the distance between the above two light-emitting regions refers to the distance between the edges of the two light-emitting regions that are close to each other, but is not limited thereto. The distance between the above two light-emitting regions can also be the distance between the centers of the two light-emitting regions in the second direction, that is, the distance between two straight lines extending along the first direction passing through the centers of the two light-emitting regions (the second direction is perpendicular to the first direction). In the embodiments of the present disclosure, by arranging the first light-emitting unit blocks in a row in the second display region at non-uniform intervals, it is possible to prevent the light-emitting layer of the first light-emitting unit block in the second display region from overlapping with the light-emitting layer of the third-color light-emitting unit in the third display region.

[0098] For example, as Figure 3 and Figure 4 shown, in at least one first sub-light-emitting unit group 310, the distance between the two center lines extending along the first direction in the two light-emitting regions of the second-color light-emitting unit pair 122 is the sixth distance D6; in at least one second sub-light-emitting unit group 320, the distance between the two center lines extending along the first direction in the two light-emitting regions of the second-color light-emitting unit pair 122 is the seventh distance D7, and the seventh distance D7 is greater than the sixth distance D6.

[0099] For example, as Figure 3 and Figure 4 shown, in at least one first sub-light-emitting unit group 310, the distance between the center line extending along the first direction in the light-emitting region of the first-color light-emitting unit 121 and the center line extending along the first direction in the light-emitting region of the second light-emitting unit block 1222 is the eighth distance D8; in at least one second sub-light-emitting unit group 320, the distance between the center line extending along the first direction in the light-emitting region of the first-color light-emitting unit 121 and the center line extending along the first direction in the light-emitting region of the second light-emitting unit block 1222 is the ninth distance D9, and the ratio of the ninth distance D9 to the eighth distance D8 is 0.8 to 1.2.

[0100] For example, asFigure 3 and Figure 4 As shown in Figure 4 , in the second display area 20, the first-color light-emitting units 121 in one row are arranged at equal intervals, the second light-emitting unit blocks 1222 in one row are arranged at equal intervals, and the third-color light-emitting units 123 in one row are arranged at equal intervals, while the first light-emitting unit blocks 1221 in one row are arranged at unequal intervals, thus facilitating the fabrication of other light-emitting units in the second light-emitting unit group except for the first light-emitting unit blocks 1221 and saving costs.

[0101] For example, as Figure 3 and Figure 4 shown, in the first light-emitting unit group 100 and the second light-emitting unit group 300, the shapes of the light-emitting areas of the first-color light-emitting units 121 are substantially the same and the areas are substantially equal; in the first light-emitting unit group 100 and the second light-emitting unit group 300, the shapes of the light-emitting areas of the third-color light-emitting units 123 are substantially the same and the areas are substantially equal. For example, in the first light-emitting unit group 100, the shapes of the light-emitting areas of the first-color light-emitting units 121 and the third-color light-emitting units 123 include hexagons; in the second light-emitting unit group 300, the shapes of the light-emitting areas of the first-color light-emitting units 121 and the third-color light-emitting units 123 include hexagons.

[0102] For example, in each light-emitting unit group, the area of the light-emitting area of the third-color light-emitting unit 123 is larger than the area of the light-emitting area of the first-color light-emitting unit 121.

[0103] For example, as Figure 3 and Figure 4 shown, the shape of the light-emitting area of the first light-emitting unit block 1221 in the first light-emitting unit group 100 is different from the shape of the light-emitting area of the first light-emitting unit block 1221 in the second light-emitting unit group 300, and the shape of the light-emitting area of the second light-emitting unit block 1222 in the first light-emitting unit group 100 is different from the shape of the light-emitting area of the second light-emitting unit block 1222 in the second light-emitting unit group 300. For example, the shapes of the first light-emitting unit block 1221 and the second light-emitting unit block 1222 in the first light-emitting unit group 100 can both be pentagons, and the shapes of the first light-emitting unit block 1221 and the second light-emitting unit block 1222 in the second light-emitting unit group 300 can both be approximately rectangles, thereby preventing the second electrodes of the third-color light-emitting units in the second light-emitting unit group from conflicting with the second electrodes of the second light-emitting unit blocks in space, and preventing the second electrodes of the first-color light-emitting units in the second light-emitting unit group from conflicting with the second electrodes of the first light-emitting unit blocks in space.

[0104] For example, the area of the light-emitting region of the second-color light-emitting units in the first light-emitting unit group 100 is different from the area of the light-emitting region of the second-color light-emitting units in the second light-emitting unit group 300. For example, the area of the light-emitting region of the second-color light-emitting units in the first light-emitting unit group 100 is larger than the area of the light-emitting region of the second-color light-emitting units in the second light-emitting unit group 300.

[0105] For example, as Figure 3 and Figure 4 shown, in the first light-emitting unit group 100 and the third light-emitting unit group 500, the shapes of the light-emitting regions of the light-emitting units that emit the same color light are different. For example, in the third light-emitting unit group 500, the shapes of the light-emitting regions of the respective light-emitting units include a circle, an ellipse, or a water-drop shape. The above-mentioned circle includes a standard circle and an approximate circle, and the approximate circle may include an approximate circle with a notch at the edge, an approximate circle with a ratio of diameters extending in each direction of 0.9 to 1.1, etc. The above-mentioned ellipse includes a standard ellipse and an approximate ellipse, and the approximate ellipse may include an approximate ellipse with a notch at the edge, an approximate ellipse with a ratio of diameters extending in each direction of 0.9 to 1.1, etc.

[0106] For example, in the third light-emitting unit group 500, the shapes of the light-emitting regions of the first-color light-emitting units 121 and the third-color light-emitting units 123 are both circles, and the shapes of the light-emitting regions of the two second-color light-emitting units are both ellipses, and the major axis of the ellipse extends along the second direction.

[0107] For example, the edge of the opening of the pixel defining layer that defines the light-emitting regions of the respective light-emitting units in the third light-emitting unit group includes a protrusion, and the light-emitting layer formed in the opening includes a notch, that is, the light-emitting region includes a notch, and the notch is the part where the second electrode of the light-emitting unit is connected to the thin-film transistor.

[0108] For example, Figure 5A is Figure 3 a partial view of the light-emitting units at the junction position of the first display region, the second display region, and the third display region in another example of the shown display substrate. Figure 5A The shown example is different from the example shown in Figure 4 that the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 and the first light-emitting unit group 100 is different.

[0109] For example, as Figure 3 and Figure 5AAs shown, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 is not greater than 1. For example, the ratio of the area of the light-emitting region of each first-color light-emitting unit 121 in the third light-emitting unit group 500 to the area of the light-emitting region of each first-color light-emitting unit 121 in the first light-emitting unit group 100 is 0.5 to 1, the ratio of the area of the light-emitting region of each second-color light-emitting unit pair 122 in the third light-emitting unit group 500 to the area of the light-emitting region of each second-color light-emitting unit pair 122 in the first light-emitting unit group 100 is 0.5 to 1, and the ratio of the area of the light-emitting region of each third-color light-emitting unit 123 in the third light-emitting unit group 500 to the area of the light-emitting region of each third-color light-emitting unit 123 in the first light-emitting unit group 100 is 0.5 to 1. For example, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 is 0.6 to 0.9. For example, the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 is 0.7 to 0.8.

[0110] For example, Figure 5A The example shown and Figure 4 The differences between the example shown and the example shown also include that in the second display area 20, the first-color light-emitting units 121 are arranged at equal intervals, the second light-emitting unit blocks 1222 are arranged at equal intervals, the third-color light-emitting units 123 are arranged at equal intervals, and the first light-emitting unit blocks 1221 are also arranged at equal intervals. Since the area ratio of the light-emitting regions of the light-emitting units of the same color in the third light-emitting unit group 500 to those in the first light-emitting unit group 100 in this example is not greater than 1, the problem of the light-emitting layer of the first light-emitting unit block in the second display area overlapping with the light-emitting layer of the third-color light-emitting unit in the third display area is not likely to occur. Therefore, the distance between the light-emitting regions of the first-color light-emitting units and the light-emitting regions of the adjacent second-color light-emitting units in each second light-emitting unit group is equal.

[0111] For example, as Figure 3 and Figure 5A shown, in the first light-emitting unit group 100 and the third light-emitting unit group 500, the shapes of the light-emitting regions of the light-emitting units that emit the same color light are different.

[0112] For example, in the third light-emitting unit group 500, the shapes of the light-emitting regions of the light-emitting units include circular, oval, or drop-shaped. The above-mentioned circular includes a standard circle and an approximate circle. The approximate circle can include an approximate circle with a notch on the edge, an approximate circle with a ratio of the diameters extending in each direction of 0.9 to 1.1, etc. The above-mentioned oval includes a standard oval and an approximate oval. The approximate oval can include an approximate oval with a notch on the edge, an approximate oval with a ratio of the diameters extending in each direction of 0.9 to 1.1, etc.

[0113] For example, in the third light-emitting unit group 500, the light-emitting regions of the first-color light-emitting units 121 and the third-color light-emitting units 123 are both elliptical, and the major axes of the ellipses are along the first direction. The light-emitting regions of the second light-emitting unit blocks 1222 and 1221 are both elliptical, and the major axes of the ellipses are along the second direction.

[0114] For example, the edge of the opening of the pixel defining layer that defines the light-emitting regions of the light-emitting units in the third light-emitting unit group includes protrusions, and the light-emitting layer formed within the opening includes notches, that is, the light-emitting region includes notches, and the notches are the portions where the second electrodes of the light-emitting units are connected to the thin-film transistors.

[0115] For example, Figure 5A the first light-emitting unit group in the illustrated example and Figure 4 the first light-emitting unit group in the illustrated example have the same features and will not be elaborated here. For example, Figure 5A the second light-emitting unit group in the illustrated example and Figure 4 in the second light-emitting unit group in the illustrated example, except for the different distribution rules of the first light-emitting unit block 1221, the other light-emitting units are all Figure 4 the same as the other light-emitting units in the illustrated example and will not be elaborated here.

[0116] For example, Figure 5B is Figure 3 a partial view of the light-emitting units at the junction position of the first display region, the second display region, and the third display region in another example of the illustrated display substrate. Figure 5B The differences between the illustrated example and Figure 5A the illustrated example include the different shapes of the light-emitting regions in the second light-emitting unit group. For example, as Figure 5B shown, in the second light-emitting unit group 300 and the third light-emitting unit group 500, the shapes of the light-emitting regions of the light-emitting units emitting the same color light are substantially the same, and the areas are substantially equal.

[0117] For example, Figure 5B the first light-emitting unit group in the illustrated example and Figure 4 the first light-emitting unit group in the illustrated example have the same features and will not be elaborated here. For example, Figure 5B the third light-emitting unit group in the illustrated example and Figure 5A the third light-emitting unit group in the illustrated example have the same features and will not be elaborated here. For example, Figure 5B the second light-emitting unit group in the illustrated example and Figure 4 in the second light-emitting unit group in the illustrated example, except for the different distribution rules of the first light-emitting unit block 1221 and the different shapes of the light-emitting units, the other light-emitting units are all Figure 4 the same as the other light-emitting units in the illustrated example and will not be elaborated here.

[0118] For example, a plurality of first pixel circuit groups 200 include a plurality of first pixel circuits 210, and a plurality of second pixel circuit groups 400 include a plurality of second pixel circuits 410. For example, in at least one second pixel circuit group 400, each second pixel circuit 410 includes two sub-pixel circuits 411 and 412, and the two sub-pixel circuits are configured to be connected to the same light-emitting unit (for example, a first-color light-emitting unit, a second-color light-emitting unit, or a third-color light-emitting unit). For example, the two sub-pixel circuits are connected to the second electrode of the same light-emitting unit. For example, in the first pixel circuit group 200, each first pixel circuit 210 includes one sub-pixel circuit, and different sub-pixel circuits are configured to be connected to different light-emitting units, that is, one sub-pixel circuit is only connected to the second electrode of one light-emitting unit. For example, the sub-pixel circuits included in the second pixel circuit may have the same structure as the sub-pixel circuits included in the first pixel circuit.

[0119] For example, Figure 6 is an equivalent diagram of the sub-pixel circuit included in the first pixel circuit. Taking Figure 6 the shown first pixel circuit for driving the first-color light-emitting unit as an example, the equivalent diagram of the first pixel circuit for driving other color light-emitting units is the same as Figure 6 the shown equivalent diagram. As Figure 6 shown, the first pixel circuit 210 includes a second reset transistor T1, a second light-emitting control transistor T5, a first light-emitting control transistor T6, a data writing transistor T4, a driving transistor T3, a threshold compensation transistor T2, a first reset control transistor T7, and a storage capacitor C. For example, the display substrate further includes a reset power signal line, a scan signal line, a power signal line, a reset control signal line, a light-emitting control signal line, and a data line.

[0120] For example, a first pole of the threshold compensation transistor T2 is connected to a first pole of the driving transistor T3, and a second pole of the threshold compensation transistor T2 is connected to a gate of the driving transistor T3; a first pole of the first reset control transistor T7 is connected to a reset power signal line to receive a reset signal Vinit, and a second pole of the first reset control transistor T7 is connected to a second electrode of a light-emitting unit (such as the first light-emitting unit 121); a first pole of the data writing transistor T4 is connected to a second pole of the driving transistor T3, and a second pole of the data writing transistor T4 is connected to a data signal line to receive a data signal Data, and a gate of the data writing transistor T4 is electrically connected to a scan signal line to receive a scan signal Gate; a first pole of a storage capacitor C is electrically connected to a power signal line, and a second pole of the storage capacitor C is electrically connected to a gate of the driving transistor T3; a gate of the threshold compensation transistor T2 is electrically connected to the scan signal line to receive a compensation control signal; a gate of the first reset transistor T7 is electrically connected to a reset control signal line to receive a reset control signal Reset(N + 1); a first pole of the second reset transistor T1 is connected to the reset power signal line to receive the reset signal Vinit, a second pole of the second reset transistor T1 is connected to a gate of the driving transistor T3, and a gate of the second reset transistor T1 is electrically connected to the reset control signal line to receive a reset control signal Reset(N); a gate of the first light-emitting control transistor T6 is electrically connected to a light-emitting control signal line to receive a light-emitting control signal EM; a first pole of the second light-emitting control transistor T5 is connected to the power signal line to receive a first power signal VDD, a second pole of the second light-emitting control transistor T5 is electrically connected to a second pole of the driving transistor T3, a gate of the second light-emitting control transistor T5 is electrically connected to the light-emitting control signal line to receive the light-emitting control signal EM, and a first electrode of the first light-emitting unit 121 is connected to a voltage terminal VSS. The above-mentioned power signal line refers to a signal line for outputting a voltage signal VDD, and can be connected to a voltage source to output a constant voltage signal, such as a positive voltage signal.

[0121] For example, the scan signal and the compensation control signal can be the same, that is, the gate of the data writing transistor T3 and the gate of the threshold compensation transistor T2 can be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gate of the data writing transistor T3 and the gate of the threshold compensation transistor T2 can also be electrically connected to different signal lines respectively, that is, the gate of the data writing transistor T3 is electrically connected to a first scan signal line, and the gate of the threshold compensation transistor T2 is electrically connected to a second scan signal line, and the signals transmitted by the first scan signal line and the second scan signal line can be the same or different, so that the gate of the data writing transistor T3 and the threshold compensation transistor T2 can be separately controlled, increasing the flexibility of controlling the pixel circuit.

[0122] For example, the light emission control signals input to the first light emission control transistor T6 and the second light emission control transistor T5 may be the same. That is, the gates of the first light emission control transistor T6 and the second light emission control transistor T5 may be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gates of the first light emission control transistor T6 and the second light emission control transistor T5 may also be respectively electrically connected to different light emission control signal lines, and the signals transmitted on the different light emission control signal lines may be the same or different.

[0123] For example, the reset control signals input to the first reset transistor T7 and the second reset transistor T1 may be the same. That is, the gates of the first reset transistor T7 and the second reset transistor T1 may be electrically connected to the same signal line to receive the same signal, reducing the number of signal lines. For example, the gates of the first reset transistor T7 and the second reset transistor T1 may also be respectively electrically connected to different reset control signal lines. At this time, the signals on the different reset control signal lines may be the same or different.

[0124] For example, as Figure 6 shown, when the display substrate is working, in the first stage of the picture display, the second reset transistor T1 is turned on to initialize the voltage of the N1 node; in the second stage of the picture display, the data is stored in the N1 node through the data writing transistor T4, the driving transistor T3, and the threshold compensation transistor T2; in the third light emission stage, the second light emission control transistor T5, the driving transistor T3, and the first light emission control transistor T6 are all turned on, and the light emitting unit is forward-conducted to emit light.

[0125] It should be noted that in the embodiments of the present disclosure, the pixel circuit of the sub-pixel may be other than Figure 6 the 7T1C (i.e., seven transistors and one capacitor) structure shown, and may also be a structure including other numbers of transistors, such as 7T2C structure, 6T1C structure, 6T2C structure, or 9T2C structure. The embodiments of the present disclosure do not limit this.

[0126] For example, Figure 7 is an equivalent diagram of two sub-pixel circuits included in the second pixel circuit. Taking Figure 7 the second pixel circuit shown for driving the first color light emitting unit as an example, the equivalent diagram of the second pixel circuit for driving other color light emitting units is the same as Figure 7 the equivalent diagram shown. As Figure 7 shown, the equivalent diagram of any one of the two sub-pixel circuits 411 and 412 in the second pixel circuit 410 is the same as Figure 6The equivalent diagrams of the sub-pixel circuits of the first pixel circuit 210 shown are basically the same. For example, they are all of the 7T1C structure. In the second pixel circuit 410, the data writing transistors T4 of the two sub-pixel circuits are connected, and the N4 nodes of the two sub-pixel circuits are connected to jointly drive the same light-emitting unit to emit light.

[0127] For example, as Figure 7 shown, when the display substrate is working, in the first stage of the screen display, the second reset transistor T1 is turned on to initialize the voltage of the N1 node; in the second stage, the same data signal Data is stored in the two N1 nodes of the two pixel circuits 600 through the two connected data writing transistors T4, and the two driving transistors T3 and the two threshold compensation transistors T2 respectively connected to the two connected data writing transistors T4; in the third light-emitting stage, the second light-emitting control transistors T5, the driving transistors T3, and the first light-emitting control transistors T6 in the two sub-pixel circuits 411 and 412 are all turned on to transmit the same data signal to the two N4 nodes. At this time, the N4 nodes of the two sub-pixel circuits 411 and 412 are connected to jointly drive the same light-emitting unit (for example, the first light-emitting unit 121) to emit light. In the embodiments of the present disclosure, the second pixel circuit in the second display area adopts a dual 7T1C design, which can achieve the purpose of increasing current and brightness.

[0128] For example, the third pixel circuit group includes multiple third pixel circuits, and the fourth pixel circuit group includes multiple fourth pixel circuits. The third pixel circuit and the fourth pixel circuit may have the same equivalent circuit diagram as the first pixel circuit, or may have the same equivalent circuit diagram as the second pixel circuit. For example, in an example of the present disclosure, both the third pixel circuit and the fourth pixel circuit have the same equivalent circuit diagram as the second pixel circuit. Then, both the third pixel circuit and the fourth pixel circuit include two sub-pixel circuits, and the two sub-pixel circuits are configured to be connected to the same light-emitting unit (for example, the first color light-emitting unit, the second color light-emitting unit, or the third color light-emitting unit). For example, the two sub-pixel circuits are connected to the second electrode of the same light-emitting unit, which can achieve the purpose of increasing current and brightness.

[0129] For example, Figure 8 is a partial planar structure diagram of the active semiconductor layer at the boundary position between the third display area and the second display area and at the boundary position between the first display area and the second display area provided according to the embodiments of the present disclosure. Figure 9 is a partial planar structure diagram of the first conductive layer at the boundary position between the third display area and the second display area and at the boundary position between the first display area and the second display area provided according to the embodiments of the present disclosure. Figure 10 is a partial planar structure diagram of the second conductive layer at the boundary position between the third display area and the second display area and at the boundary position between the first display area and the second display area provided according to the embodiments of the present disclosure.Figure 11 A partial planar structure diagram of the source-drain metal layer at the junction position between the third display area and the second display area and at the junction position between the first display area and the second display area provided according to an embodiment of the present disclosure, Figure 12 is Figures 8 to 11 a stacked schematic diagram of the active semiconductor layer, the first conductive layer, the second conductive layer, and the source-drain metal layer shown in the figure.

[0130] For example, as Figures 8 to 12 shown, the active semiconductor layer 3100 can be formed by patterning a semiconductor material. The active semiconductor layer 3100 can be used to fabricate the active layers of the second reset transistor T1, the threshold compensation transistor T2, the driving transistor T3, the data writing transistor T4, the second light-emitting control transistor T5, the first light-emitting control transistor T6, and the first reset control transistor T7 described above. The active semiconductor layer 3100 includes the active layer patterns (channel regions) and doping region patterns (source-drain doping regions) of the transistors in each sub-pixel, and the active layer patterns and doping region patterns of the transistors in the same pixel circuit are integrally provided.

[0131] It should be noted that the active layer can include an integrally formed low-temperature polysilicon layer, and the source region and the drain region can be made conductive through doping or the like to achieve electrical connection of each structure. That is, the active semiconductor layer of each transistor in each sub-pixel is an overall pattern formed of p-silicon, and each transistor in the same pixel circuit includes a doping region pattern (i.e., the source region and the drain region) and an active layer pattern, and the active layers of different transistors are separated by a doping structure.

[0132] For example, the active semiconductor layer 3100 can be made of amorphous silicon, polysilicon, oxide semiconductor materials, etc. It should be noted that the above-mentioned source region and drain region can be regions doped with n-type impurities or p-type impurities.

[0133] Figure 8 Each dashed rectangular box in the figure shows the overlapping parts of the first conductive layer 3200 and the active semiconductor layer 3100. As the channel regions of each transistor (i.e., the above-mentioned active layer patterns), the active semiconductor layer on both sides of each channel region is made conductive through processes such as ion doping as the first pole and the second pole of each transistor (i.e., the above-mentioned doping region patterns). The source and drain of the transistor can be symmetric in structure, so there is no physical difference between its source and drain. In the embodiments of the present disclosure, in order to distinguish the transistors, except for the gate as the control pole, one of the poles is directly described as the first pole and the other as the second pole. Therefore, the first pole and the second pole of all or part of the transistors in the embodiments of the present disclosure can be interchanged as needed.

[0134] For example, each pixel circuit group among a plurality of first pixel circuit groups, a plurality of second pixel circuit groups, and a plurality of third pixel circuit groups includes a plurality of thin film transistors. For example, the plurality of thin film transistors includes a second reset transistor T1, a threshold compensation transistor T2, a driving transistor T3, a data writing transistor T4, a second light emission control transistor T5, a first light emission control transistor T6, and a first reset control transistor T7.

[0135] For example, the active semiconductor layer 3100 includes an active layer pattern 3102 and a doping region pattern 3103 of each thin film transistor, and the active semiconductor layer 3100 further includes a dummy pattern 3101. For example, the dummy pattern 3101 may be located in the third display region 30. For example, the dummy pattern 3101 may include a plurality of block patterns arranged along the second direction, and the plurality of block patterns may be evenly distributed or unevenly distributed, which is not limited in the embodiments of the present disclosure.

[0136] For example, the display substrate includes a gate insulating layer on a side of the active semiconductor layer away from the substrate, for insulating the active semiconductor layer 3100 described above from a first conductive layer 3200 (i.e., a gate metal layer) formed subsequently. Figure 9 The first conductive layer 3200 included in the display substrate is shown. The first conductive layer 3200 is disposed on the gate insulating layer, so as to be insulated from the active semiconductor layer 3100. The first conductive layer 3200 may include a second pole CC2 of a capacitor C, a plurality of scan signal lines 043 extending along the second direction (the X direction in the figure), a plurality of reset control signal lines 044, a plurality of light emission control signal lines 045, and gates of the second reset transistor T1, the threshold compensation transistor T2, the driving transistor T3, the data writing transistor T4, the second light emission control transistor T5, the first light emission control transistor T6, and the first reset control transistor T7.

[0137] For example, as Figures 8 to 12As shown, the gate of the data writing transistor T3 can be the overlapping part of the scanning signal line 043 and the active semiconductor layer 3100; the gate of the first light emission control transistor T6 can be the first overlapping part of the light emission control signal line 045 and the active semiconductor layer 3100, and the gate of the second light emission control transistor T5 can be the second overlapping part of the light emission control signal line 045 and the active semiconductor layer 3100. The gate of the second reset transistor T1 is the first overlapping part of the reset control signal line 044 and the active semiconductor layer 3100, and the gate of the first reset control transistor T7 is the second overlapping part of the reset control signal line 044 and the active semiconductor layer 3100. The threshold compensation transistor T2 can be a thin film transistor with a double gate structure. The first gate of the threshold compensation transistor T2 can be the overlapping part of the scanning signal line 043 and the active semiconductor layer 3100, and the second gate of the threshold compensation transistor T2 can be the overlapping part of the protruding structure P protruding from the scanning signal line 043 and the active semiconductor layer 3100. As Figure 9 shown, the gate of the driving transistor T1 can be the second pole CC2 of the capacitor C.

[0138] For example, as Figures 8 to 12 shown, the scanning signal line 043, the reset control signal line 044, and the light emission control signal line 045 are arranged in the first direction (Y direction). The scanning signal line 043 is located between the reset control signal line 044 and the light emission control signal line 045.

[0139] For example, in the first direction, the second pole CC2 of the capacitor C (i.e., the gate of the driving transistor T1) is located between the scanning signal line 043 and the light emission control signal line 045. The protruding structure P protruding from the scanning signal line 043 is located on the side of the scanning signal line 043 away from the light emission control signal line 045.

[0140] For example, the gate insulating layer located on the side of the first conductive layer 3200 away from the active semiconductor layer 3100 includes a plurality of vias for exposing the doped region pattern and the dummy pattern in the active semiconductor layer 3100.

[0141] For example, a first insulating layer is formed on the first conductive layer 3200 for insulating the first conductive layer 3200 from the subsequently formed second conductive layer 3300.

[0142] For example, the first insulating layer includes vias for exposing the dummy pattern, the doped region pattern of some thin film transistors, and the second pole CC2 of the capacitor C.

[0143] For example, as Figures 8 to 12As shown, the second conductive layer 3300 includes the first pole CC1 of the capacitor C and a plurality of reset power signal lines 041 extending along the second direction. The first pole CC1 of the capacitor C and the second pole CC2 of the capacitor C at least partially overlap to form the capacitor C.

[0144] For example, as Figures 8 to 12 shown, the source-drain metal layer 3400 includes data lines 910 and power signal lines 920 extending along the second direction. The data lines 910 are electrically connected to the second pole of the data writing transistor T2 through vias penetrating the gate insulating layer, the first insulating layer, and the second insulating layer. The power signal lines 920 (for example, the power signal lines in the first display area) are electrically connected to the first pole of the second light-emitting control transistor T5 through vias penetrating the gate insulating layer, the first insulating layer, and the second insulating layer. The power signal lines 920 and the data lines 910 are alternately arranged along the first direction. The power signal lines 920 are electrically connected to the first pole CC1 of the capacitor C through vias penetrating the second insulating layer.

[0145] For example, a passivation layer and a planarization layer can be provided on the side of the above-mentioned source-drain metal layer 3400 away from the substrate for protecting the above-mentioned source-drain metal layer 3400.

[0146] For example, as Figures 8 to 12 shown, the display substrate provided by the embodiment of the present disclosure further includes a plurality of first connection portions 051. The first ends of at least some of the first connection portions 051 are connected to the second poles of the data writing transistors T4 of one sub-pixel circuit in the second pixel circuit 410, and the second ends of the first connection portions 051 are connected to the second poles of the data writing transistors T4 of another sub-pixel circuit in the second pixel circuit 410 so that the two data writing transistors T4 of the second pixel circuit 410 are connected to the same data line 910. For example, along the first direction, at least some of the first connection portions 051 are located between the second pole of the data writing transistor T2 in one sub-pixel circuit and the first pole of the first reset control transistor T7.

[0147] In the embodiment of the present disclosure, the second poles of the data writing transistors of at least two sub-pixel circuits (i.e., at least one second pixel circuit) in the second display area are connected through the first connection portions to drive the same light-emitting unit to emit light, which can increase the current and brightness of the light-emitting units in the second display area. For example, the current and brightness of the light-emitting units in the second display area can be increased to 1.8 to 2 times that in the case of driving by one sub-pixel circuit, realizing a more uniform visual display effect of the full-screen.

[0148] For example, along the first direction, the first connection portion 051 is located between the second pole of the threshold compensation transistor T3 in one sub-pixel circuit and the first pole of the first reset control transistor T7.

[0149] For example, the first connection portion 051 and the reset power signal line 041 are disposed on the same layer.

[0150] For example, a second insulating layer is formed on the second conductive layer 3300 described above to insulate the second conductive layer 3300 from the source-drain metal layer 3400 formed subsequently.

[0151] For example, the second insulating layer includes vias that expose structures such as the dummy pattern.

[0152] For example, the source-drain metal layer is connected to the doped region pattern through a first via in the insulating layer between it and the active semiconductor layer. In the embodiments of the present disclosure, by setting a dummy pattern at a position outside the edge of the second display region, and the insulating layers located between the source-drain metal layer and the active semiconductor layer are all patterned (e.g., etched) to expose the dummy pattern, it is possible to form vias in the insulating layer within the second display region through relatively uniform etching, thereby ensuring good etching uniformity of the vias in the insulating layer corresponding to the driving transistors within the second display region. For example, the insulating layer between the dummy pattern and the planarization layer is all patterned to form vias to expose the dummy pattern, and the planarization layer is configured to fill the vias.

[0153] For example, as Figures 8 to 12 shown, the second pixel circuit 410 includes two adjacent sub-pixel circuits. The two adjacent sub-pixel circuits drive the same light-emitting unit to emit light, and the two data writing transistors of the two adjacent sub-pixel circuits are connected to the same data line. The first pixel circuit 210 only includes one sub-pixel circuit. Each of the two adjacent sub-pixel circuits drives one light-emitting unit to emit light. The two data writing transistors in the two adjacent pixel circuits are independent of each other and are respectively connected to different data lines. The main differences in the layout of the first pixel circuit and the second pixel circuit in the embodiments of the present disclosure lie in whether the first connection portion is provided, the setting of the position of the second pole of the data writing transistor connected to the first connection portion, and the positional relationship between the fourth connection portion in the source-drain metal layer and the data line.

[0154] For example, as Figures 8 to 12 shown, the density of multiple first pixel circuits 210 is the first density, and the density of multiple second pixel circuits 410 is the second density. The first density is not less than the second density. For example, the first density is greater than the second density. In the embodiments of the present disclosure, "the first density is greater than the third density" may mean that the number of first pixel circuits is greater than the number of second pixel circuits under the same area.

[0155] For example, as Figures 8 to 12As shown, each first pixel circuit 210 includes only one sub-pixel circuit, and each second pixel circuit 410 includes two sub-pixel circuits. The density of sub-pixel circuits in the first display area is approximately equal to the density of sub-pixel circuits in the second display area, that is, the number of sub-pixel circuits included in the first pixel circuit is approximately equal to the number of sub-pixel circuits included in the second pixel circuit under the same area.

[0156] For example, in the case where each second pixel circuit includes two sub-pixel circuits, only one sub-pixel circuit can be connected to the light-emitting unit, or two sub-pixel circuits can be connected to the same light-emitting unit, and the embodiments of the present disclosure do not limit this. When two sub-pixel circuits are connected to the same light-emitting unit, the current and brightness of the light-emitting unit can be increased to achieve a more uniform visual display effect for the full-screen.

[0157] For example, as Figures 8 to 12 shown, each pixel circuit further includes: a second connection portion 052 and a third connection portion 053 disposed on the same layer as the data line 910. The second connection portion 052 is configured to connect the second pole of the threshold compensation transistor T2 and the gate of the driving transistor T3, and the third connection portion 053 is configured to connect the first pole of the first reset control transistor T7 and the reset power signal line 041. For example, one end of the second connection portion 052 is electrically connected to the second pole of the threshold compensation transistor T2 through a via hole penetrating the gate insulating layer, the first insulating layer, and the second insulating layer, and the other end of the second connection portion 052 is electrically connected to the gate of the driving transistor T3 (i.e., the second pole CC2 of the capacitor C) through a via hole penetrating the first insulating layer and the second insulating layer. One end of the third connection portion 053 is electrically connected to the reset power signal line 041 through a via hole penetrating the second insulating layer, and the other end of the third connection portion 053 is electrically connected to the first pole of the first reset control transistor T7 through a via hole penetrating the gate insulating layer, the first insulating layer, and the second insulating layer.

[0158] For example, as Figures 8 to 12 shown, the first connection portion 051 and the data line 910 are located on different layers, and along the third direction perpendicular to the substrate, each first connection portion 051 overlaps with the data line 910 and the power signal line 920. For example, a data line 910 and a power signal line 920 are provided between two data writing transistors T4 included in the second pixel circuit 410, and the first connection portion 051 connecting the two data writing transistors T4 overlaps with both the data line 910 and the power signal line 920.

[0159] For example, as Figures 8 to 12As shown, each pixel circuit further includes a fourth connection portion 054 disposed on the same layer as the data line 910. The fourth connection portion 054 is configured to connect the first connection portion 051 and the second pole of the data writing transistor T4. There is a gap between the fourth connection portion 054 of a sub-pixel circuit in the second pixel circuit 410 and the adjacent data line 910. The fourth connection portion 054 of another sub-pixel circuit in the second pixel circuit 410 and the data line 910 are of an integral structure to enable the second pixel circuit 410 to be connected to only one data line 910. In the above "there is a gap between the fourth connection portion 054 and the adjacent data line 910", the "adjacent data line" means that there is no other data line between the fourth connection portion 054 and the data line 910.

[0160] For example, as Figures 8 to 12 shown, the fourth connection portion 054 integrated with the data line 910 is a first sub-portion 0541, and the fourth connection portion 054 having a gap with the adjacent data line 910 is a second sub-portion 0542. Since there is no design of pixel circuit pairs in the first pixel circuit, the fourth connection portions in two adjacent pixel circuits arranged along the first direction or the second direction in the first pixel circuit are all of an integral structure with the data line to achieve the electrical connection between each pixel circuit and the corresponding data line.

[0161] For example, as Figures 8 to 12 shown, the display substrate further includes a plurality of covering portions S disposed on the same layer as the first connection portion 051. Each threshold compensation transistor T2 includes two gates and an active semiconductor layer 3100 located between the two gates. Along the third direction, the covering portion S overlaps with the active semiconductor layer 3100 between the two gates, the data line 910, and the power supply signal line 920.

[0162] For example, the active semiconductor layer between the two channels of the dual-gate threshold compensation transistor T2 is in a floating state when the threshold compensation transistor T2 is turned off, and is prone to jump due to the influence of the surrounding line voltage, which will affect the leakage current of the threshold compensation transistor T2, and further affect the emission brightness. In order to keep the voltage of the active semiconductor layer between the two channels of the threshold compensation transistor T2 stable, it is designed that the covering portion S forms a capacitor with the active semiconductor layer between the two channels of the threshold compensation transistor T2. The covering portion S can be connected to the power supply signal line 920 to obtain a constant voltage. Therefore, the voltage of the active semiconductor layer in the floating state can be kept stable. The covering portion S overlaps with the active semiconductor layer between the two channels of the dual-gate threshold compensation transistor T2, and can also prevent the active semiconductor layer between the two gates from being illuminated and changing its characteristics. For example, it can prevent the voltage of this part of the active semiconductor layer from changing to prevent crosstalk. For example, the power supply signal line 920 can be electrically connected to the covering portion S through a via hole penetrating the second insulating layer to provide a constant voltage for the covering portion S.

[0163] For example, as Figures 8 to 12 shown, the first connection part 051 includes a main body connection part extending in the second direction and two end parts located at both ends of the main body connection part and extending in the second direction. The two end parts are respectively connected to the two fourth connection parts 054 of the second pixel circuit 410. The main body connection part and the two end parts form a broken line shape to keep a distance from the covering part. The embodiment of the present disclosure does not limit the shape of the first connection part, as long as it can keep a certain distance from other structures arranged in the same layer. For example, the main body connection part of the first connection part can be a straight line type, or a broken line type or a wavy line type.

[0164] For example, in the first direction, the distance between the covering part S and the second pole of the threshold compensation transistor T2 is less than the distance between the covering part S and the first pole of the first reset control transistor T7, that is, the covering part S is closer to the threshold compensation transistor T2. Thus, for the convenience of design and to keep a certain interval between the first connection part 051 and the covering part S, the first connection part 051 is arranged to be closer to the first pole of the first reset transistor T7.

[0165] For example, as Figures 8 to 12 shown, the plurality of data lines 910 includes a first sub-data line 911 and a second sub-data line 912; the first display area 10 includes a first pixel circuit column 201, and the second display area 20 includes a second pixel circuit column 401. For example, the first pixel circuit column 201 includes one column of sub-pixel circuits, and the second pixel circuit column 401 includes two columns of sub-pixel circuits.

[0166] For example, as Figures 8 to 12 shown, the first pixel circuit column 201 and the second pixel circuit column 401 are located in different columns, that is, any column of sub-pixel circuits in the second pixel circuit column 401 is located in a different column from the first pixel circuit column. For example, the first sub-data line 911 is connected to the first pixel circuit column 201, and the second sub-data line 912 is connected to the second pixel circuit column 401. For example, the second sub-data line 912 is connected to one column of sub-pixel circuits in the second pixel circuit column 401.

[0167] For example, as Figures 8 to 12 shown, the first sub-data line 911 and the second sub-data line 912 are connected through a data line connection part 056. The extending direction of the data line connection part 056 intersects with the first direction, and the data line connection part 056 and the data line 910 are located in different layers.

[0168] For example, as Figures 1 to 12As shown, at the junction of the first display area 10 and the second display area 20, that is, at the interval between the first pixel circuit 210 and the second pixel circuit 410, some data lines are provided with breaks so that the data lines located in the first display area 10 and the data lines located in the second display area 20 are disconnected at the above-mentioned interval. In the embodiment of the present disclosure, the junction of the first display area 10 and the second display area 20 refers to the interval between the first pole of the first reset transistor of the pixel circuit in the row of pixel circuits in the first display area 10 close to the second display area 20 and the second pole of the data writing transistor.

[0169] For example, as Figures 1 to 12 shown, an interval is provided between the data line 910 located in the second display area 20 and the first sub-data line 911 that is on the same straight line (a straight line extending in the Y direction). The data line 910 located in the second display area 20 is not used to transmit data signals, and the first sub-data line 911 is connected to the second sub-data line 912 through a data line connection portion 056. Then, the first sub-data line 911 and the second sub-data line 912 are configured to transmit the same data signal. For example, as Figures 1 to 12 shown, the second sub-data line 912 is not only connected to the second pixel circuit column 401, but also bypasses the edge of the third display area and passes through the transition area to provide a data line number for the sub-pixel circuit in the transition area.

[0170] For example, as Figures 8 to 12 shown, the first display area 10 further includes a third pixel circuit column 202, and the second display area 20 further includes a fourth pixel circuit column 402. For example, the third pixel circuit column 202 includes a column of sub-pixel circuits, and the fourth pixel circuit column 402 includes two columns of sub-pixel circuits. For example, at least a part of the third pixel circuit column 202 and the fourth pixel circuit column 402 are located in the same column. For example, one column of sub-pixel circuits in the third pixel circuit column 202 and the fourth pixel circuit column 402 are located in the same column.

[0171] For example, as Figures 8 to 12 shown, the multiple data lines 910 further include a third sub-data line 913 and a fourth sub-data line 914. The third sub-data line 913 is connected to the third pixel circuit column 202, and the fourth sub-data line 914 is connected to the fourth pixel circuit column 402. For example, the fourth sub-data line 914 is connected to one column of sub-pixel circuits in the fourth pixel circuit column 402.

[0172] For example, as Figures 8 to 12 shown, the third sub-data line 913 and the fourth sub-data line 914 are a continuous data line extending in the first direction.

[0173] For example, as Figures 1 to 12As shown, at the junction of the first display area 10 and the second display area 20, that is, at the interval between the first pixel circuit 210 and the second pixel circuit 410, some data lines are continuous, and thus the continuous data lines are configured to transmit the same data signal to the first pixel circuit and the second pixel circuit connected thereto.

[0174] For example, as Figures 1 to 12 shown, the data line 910 further includes a fifth sub-data line 915 and a sixth sub-data line 916, and the first display area 10 further includes a fifth pixel circuit column 203 and a sixth pixel circuit column 204. The fifth sub-data line 915 is connected to the fifth pixel circuit column 203, and the sixth sub-data line 916 is connected to the sixth pixel circuit column 204. The fifth sub-data line 915 is insulated from the data lines in the second display area 20, and the sixth sub-data line 916 is insulated from the data lines in the second display area 20. Then, the fifth sub-data line 915 and the sixth sub-data line 916 are only configured to provide data signals to the first pixel circuits in the first display area 10.

[0175] For example, as Figure 12 shown, a column of sub-pixel circuits in the fifth pixel circuit column 203 is in the same column as a column of sub-pixel circuits in the second pixel circuit column 401, and a column of sub-pixel circuits in the sixth pixel circuit column 204 is in the same column as another column of sub-pixel circuits in the second pixel circuit column 401.

[0176] For example, as Figure 12 shown, the data line that is in the same straight line as the fifth sub-data line 915 and is in the second display area 20 is not connected to any pixel circuit, and there is an interval between it and the fifth sub-data line 915; the data line that is in the same straight line as the sixth sub-data line 916 and is in the second display area 20 is not connected to any pixel circuit, and there is an interval between it and the fifth sub-data line 915.

[0177] For example, Figure 13 To set a partial planar structure schematic diagram of the second electrode of the light-emitting unit as shown in Figure 12 on the pixel circuit layout shown in Figure 4 shown. As Figures 1 to 13 shown, the second display area 20 may include three rows of light-emitting units, and the second pixel circuits connected to the three rows of light-emitting units are arranged in two rows. Then, the second light-emitting unit block 1222 in the second light-emitting unit group 300 is in the same row as the first-color light-emitting unit 121 and the third-color light-emitting unit 123 in the first light-emitting unit group 100, but the second pixel circuit 410 connected to the second light-emitting unit block 1222 in the second light-emitting unit group 300 and the first pixel circuit 210 connected to the first-color light-emitting unit 121 in the first light-emitting unit group 100 are in different rows.

[0178] In the embodiments of the present disclosure, data signals are transmitted from a source driver integrated circuit located on a side of the first display area away from the second display area to pixel circuits in the first display area, the second display area, and partial pixel circuits in the transition area via data lines. The data signals transmitted to the pixel circuits connected to a color light-emitting unit in the second display area should be the same as the data signals transmitted to the pixel circuits connected to the same color light-emitting unit in the first display area, and the data signals transmitted to the pixel circuits connected to a color light-emitting unit in the second display area should be the same as the data signals transmitted to the pixel circuits connected to the same color light-emitting unit in the transition area. Thus, when the same first pixel circuit column in the first display area is connected to the same data line, and two sub-pixel circuits in the second pixel circuit in the second display area are connected to the same data line, for example, it is easy to have a problem that the data signals transmitted to the first pixel circuit connected to the first color light-emitting unit in the first display area are the same as the data signals transmitted to the second pixel circuit connected to the second color light-emitting unit pair in the second display area, resulting in a mismatch of data signals between the first display area and the second display area.

[0179] For example, as Figures 1 to 13 shown, in the embodiments of the present disclosure, multiple light-emitting units connected to the third sub-pixel circuit column 202 in the first display area 10 include a first color light-emitting unit 121 and a third color light-emitting unit 123, multiple light-emitting units connected to the first pixel circuit column 201 in the first display area 10 include a second color light-emitting unit pair 122, multiple light-emitting units connected to the second pixel circuit column 401 in the second display area 20 include a second color light-emitting unit pair 122, and multiple light-emitting units connected to the fourth pixel circuit column 402 in the second display area 20 include a first color light-emitting unit 121 and a third color light-emitting unit 123 as an example.

[0180] For example, in the first display area 10, the first color light-emitting unit 121 and the third color light-emitting unit 123 are located in different rows, the first light-emitting unit block 1221 and the second light-emitting unit block 1222 are arranged along the Y direction, the first color light-emitting unit 121 and the second color light-emitting unit pair 122 are arranged along the X direction, and the directions in which the first color light-emitting unit 121 points to the third color light-emitting unit 123 in two adjacent first light-emitting unit groups 100 are opposite.

[0181] For example, the first pixel circuit column 201, the fifth pixel circuit column 203, the sixth pixel circuit column 204, and the third pixel circuit column 202 form a group of pixel circuit columns. The light-emitting units connected to four first pixel circuits in the first row of the first display area 10 close to the second display area 20 and within the group of pixel circuit columns are, in sequence, the first light-emitting unit block 1221, the third-color light-emitting unit 123, the second light-emitting unit block 1222, and the first-color light-emitting unit 121. The four light-emitting units connected to the pixel circuits in the second row of the pixel circuit columns within the above-mentioned group of pixel circuit columns and in the first display area close to the second display area are, in sequence, the second light-emitting unit block 1222, the first-color light-emitting unit 121, the first light-emitting unit block 1221, and the third-color light-emitting unit 123. Thus, the arrangement of the first-color light-emitting unit and the third-color light-emitting unit connected to the pixel circuits of the fifth pixel circuit column and the third pixel circuit column is different, and the arrangement of the first light-emitting unit block and the second light-emitting unit block connected to the pixel circuits of the first pixel circuit column and the sixth pixel circuit column is different. The data signals transmitted by the data lines are related to the arrangement of the corresponding color light-emitting units, and both the first display area 10 and the second display area 20 should transmit matching data signals according to the above light-emitting unit arrangement method.

[0182] For example, as Figures 1 to 13 shown, the multiple light-emitting units 20 connected to the fourth pixel circuit column 402 in the second display area 20 include the first-color light-emitting unit 121 and the third-color light-emitting unit 123 arranged alternately. The light-emitting unit connected to the pixel circuit of the second pixel circuit column 401 in the row of the second display area 20 close to the first display area 10 is, for example, the third-color light-emitting unit 123. The multiple light-emitting units connected to the third pixel circuit column 202 in the first display area 10 include the first-color light-emitting unit 121 and the third-color light-emitting unit 123 arranged alternately. The light-emitting unit connected to the pixel circuit of the third pixel circuit column 202 in the row of the first display area 10 close to the second display area 20 is the first-color light-emitting unit 121. Thus, among the pixel circuits in the row of the first display area close to the second display area and connected to the third sub-data line, the pixel circuits are connected to the first-color light-emitting unit, and among the pixel circuits in the row of the second display area close to the first display area and connected to the fourth sub-data line, the pixel circuits are connected to the third-color light-emitting unit. The arrangement of the light-emitting units matches the data signals transmitted by the third sub-data line. Then, the third sub-data line and the fourth sub-data line are a data line extending continuously along the first direction, that is, the third sub-data line and the fourth sub-data line can remain connected at the junction of the first display area and the second display area without being disconnected at the junction of the two display areas.

[0183] For example, as Figures 1 to 13As shown, a plurality of second color light-emitting unit pairs 122 connected to the second pixel circuit columns 401 in the second display area 20 include a first light-emitting unit block 1221 and a second light-emitting unit block 1222 arranged alternately. The light-emitting unit connected to the pixel circuit of the second pixel circuit column 401 in a row close to the first display area 10 in the second display area 20 is, for example, the second light-emitting unit block 1222. A plurality of second color light-emitting unit pairs 122 connected to the sixth pixel circuit column 204 in the first display area 10 include a first light-emitting unit block 1221 and a second light-emitting unit block 1222 arranged alternately. The light-emitting unit connected to the pixel circuit of the sixth pixel circuit column 204 in a row close to the second display area 20 in the first display area 10 is also the second light-emitting unit block 1222. Thus, the light-emitting units connected to the pixel circuits of the second pixel circuit column in a row of pixel circuits close to the second display area in the first display area and the light-emitting units connected to the pixel circuits of the sixth pixel circuit column in a row of pixel circuits close to the first display area in the second display area are of the same type of light-emitting unit. Then, the data signals of the second sub-data line connected to the second pixel circuit column in the first display area and the data signals of the sixth sub-data line connected to the sixth pixel circuit column in the second display area do not match. Therefore, there is a gap between the second sub-data line and the sixth sub-data line at the junction of the first display area and the second display area.

[0184] For example, as Figures 1 to 13 shown, a plurality of second color light-emitting unit pairs 122 connected to the first pixel circuit column 201 in the first display area 10 include a first light-emitting unit block 1221 and a second light-emitting unit block 1222 arranged alternately, and the light-emitting unit connected to the pixel circuit of the first sub-pixel circuit column 201 in a row close to the second display area 20 in the first display area 10 is the first light-emitting unit block 1221. Thus, the data signals of the second sub-data line connected to the second pixel circuit column in the second display area and the data signals of the first sub-data line connected to the first pixel circuit column in the first display area match. Then, the first sub-data line in the first display area is connected to the second sub-data line in the second display area through a data line connection part to meet the unified algorithm processing of the integrated circuit (IC) in the first display area and the second display area.

[0185] In the embodiments of the present disclosure, at the position where the first display area and the second display area meet, the first sub-data line and the second sub-data line are connected through a data line connection part, so as to ensure the matching of the data signals transmitted from the data line to the light-emitting units in the first display area and the data signals transmitted from the data line to the light-emitting units in the second display area.

[0186] For example, as Figures 1 to 13 shown, the data line connection part 056 and the plurality of data lines 910 are located on different layers.

[0187] For example, asFigures 1 to 13 As shown, the data line connection part 056 and the reset power signal line 041 are located on the same layer for convenient design.

[0188] For example, as Figures 8 to 13 shown, the multiple power signal lines 920 include multiple first sub-power signal lines 921 and multiple second sub-power signal lines 922. The multiple first sub-power signal lines 921 are connected to multiple first pixel circuit groups 200, and the multiple second sub-power signal lines 922 are connected to multiple second pixel circuit groups 400. Each first sub-power signal line 921 is configured to transmit a first power signal, and each second sub-power signal line 922 is configured to transmit a second power signal. In an embodiment of the present disclosure, when the first pixel circuit includes only one sub-pixel circuit and the second pixel circuit includes two sub-pixel circuits, the magnitudes of the power signals required by the first pixel circuit and the second pixel circuit are different. For example, the power signal required by the first pixel circuit is less than the power signal required by the second pixel circuit, then the first sub-power signal line connected to the first pixel circuit and the second sub-power signal line connected to the second pixel circuit are configured to transmit different power signals.

[0189] For example, among the multiple second sub-power signal lines 922, there is a second sub-power signal line 922 that is located on the same straight line as at least one first sub-power signal line 921. An interval G is provided between the first sub-power signal line 921 and the second sub-power signal line 922 that are located on the same straight line. In an embodiment of the present disclosure, two signal lines located on the same straight line mean that the two signal lines can be penetrated by the same straight line.

[0190] For example, the first power signal can be transmitted from an integrated circuit located on one side of the first display area far from the second display area to the pixel circuit in the first display area through the first sub-power signal line. For example, the second sub-power signal line can be connected to the third sub-power signal line in the transition area through the structure in the second conductive layer, and the third sub-power signal line in the transition area is connected to another integrated circuit to provide the second power signal for the second sub-power signal line.

[0191] For example, Figure 14 is a schematic plan view of a display substrate provided for an example according to an embodiment of the present disclosure, Figure 15 is Figure 14 a schematic partial structure view of the shown display substrate. The difference between this example and the Figures 1 to 13 shown example is that this example further includes a light-shielding layer.

[0192] For example, as Figure 14 and Figure 15 shown, the display substrate further includes a light-shielding layer 930, which is located at the edge of the third display area 30. For example, as Figure 14 and Figure 15As shown, the light-shielding layer 930 overlaps with the second sub-data line 912 and the fourth sub-data line 914 in a direction perpendicular to the substrate 01, that is, the orthographic projection of the light-shielding layer 930 on the substrate 01 overlaps with the orthographic projections of the second sub-data line 912 and the fourth sub-data line 914 on the substrate 01. By providing a light-shielding layer at the edge of the third display area in the embodiments of the present disclosure, diffraction of the data lines located at the edge of the third display area and arranged in a winding manner can be prevented.

[0193] For example, the shape of the light-shielding layer 930 can be an annular shape, but is not limited thereto, and can be changed according to the shape of the third display area. For example, the outer ring of the light-shielding layer 930 can be an arc shape or a polyline shape to match the position of the light-emitting unit group.

[0194] For example, the light-shielding layer 930 is located on the side of the film layer where the second sub-data line 912 is located (i.e., the film layer where the data connection part is located) away from the film layer where the power supply signal line 920 is located. For example, the light-shielding layer 930 can be Figure 9 on the same layer as the first conductive layer shown, which is convenient for manufacturing and saves costs.

[0195] For example, at least one of the multiple second sub-power supply signal lines 922 is connected to the light-shielding layer 930 to reduce the resistance of the second sub-power supply signal line.

[0196] The characteristics of each light-emitting unit group and pixel circuit group in the first display area, the second display area, and the third display area in this example can be the same as those of the corresponding structures in the Figures 1 to 13 example shown, and will not be elaborated here.

[0197] Another embodiment of the present disclosure provides a display device, which includes any of the above display substrates.

[0198] For example, the display device provided by the embodiments of the present disclosure can be an organic light-emitting diode display device.

[0199] For example, in the display device provided by the embodiments of the present disclosure, by providing a second display area between the third display area and the first display area, it is beneficial to improve the cyan or darkening phenomenon at the boundaries where the third display area and the first display area are close to each other, and thus improve the display image quality of the third display area (the area where the under-screen camera is located).

[0200] For example, the display device may further include a cover plate located on the display side of the display substrate. For example, the display device may further include a functional component located on the side of the substrate away from the light-emitting element, and the functional component is opposite to the second display area.

[0201] For example, the functional component includes at least one of a camera module (e.g., a front camera module), a 3D structured light module (e.g., a 3D structured light sensor), a time-of-flight 3D imaging module (e.g., a time-of-flight sensor), an infrared sensing module (e.g., an infrared sensing sensor), etc.

[0202] For example, the front camera module is usually enabled during user selfies or video calls, and the pixel display area of the display device displays the image obtained from the selfie for the user to view. The front camera module includes, for example, a lens, an image sensor, an image processing chip, etc. The optical image generated by the scene through the lens is projected onto the surface of the image sensor (the image sensor includes two types: CCD and CMOS) and transformed into an electrical signal. After being converted from analog to digital by the image processing chip, it becomes a digital image signal and is then sent to the processor for processing and outputting the image of the scene on the display screen.

[0203] For example, a 3D structured light sensor and a time-of-flight (ToF) sensor can be used for face recognition to unlock the display device, etc.

[0204] For example, the functional component may only include a camera module to implement the function of selfies or video calls; for example, the functional component may further include a 3D structured light module or a time-of-flight 3D imaging module to implement face recognition and unlocking, etc. This embodiment includes but is not limited to this.

[0205] For example, the display device can be any product or component with a display function, such as a mobile phone with an under-screen camera, a tablet computer, a laptop computer, a navigator, etc. This embodiment is not limited to this.

[0206] The following points need to be explained:

[0207] (1) In the accompanying 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.

[0208] (2) Without conflict, the features in the same embodiment and different embodiments of the present disclosure can be combined with each other.

[0209] The above is only an exemplary implementation manner of the present disclosure, rather than being used to limit the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
