Description

Technical Field

[0001] Embodiments of the present disclosure relate to a pixel array structure and a display device.

Background Art

[0002] With the diverse development of the application fields and product forms of organic light-emitting diode (OLED) display devices, people's needs for electronic products using OLED display devices are also increasing. These electronic products include smartphones, TVs, computers, tablet PCs, navigators, in-vehicle central control screens, and smartwatches, etc.

[0003] An organic light-emitting diode (OLED) display device includes a driving substrate, an organic light-emitting element, and a sealing layer. The organic light-emitting element includes an anode, a cathode, and an organic light-emitting layer located between the anode and the cathode. The organic light-emitting element is located on the driving substrate and connected to a pixel driving circuit on the driving substrate. The sealing layer is located on the side of the organic light-emitting element away from the driving substrate to seal the organic light-emitting element and prevent the organic light-emitting element from deteriorating due to corrosion by water or oxygen.

[0004] In an organic light-emitting diode (OLED) display device, the organic light-emitting elements are arranged in an array on the driving substrate and may function as sub-pixels. The light-emitting layer of the organic light-emitting element is usually deposited with an organic light-emitting material at a corresponding position through a fine metal mask (FMM). Therefore, the size of the opening of the high-precision metal mask directly determines the size of the sub-pixel. Due to limitations in the manufacturing process of the high-precision metal mask, the size of the opening cannot be further reduced. Therefore, it is difficult to obtain a high-resolution organic light-emitting diode (OLED) display device with a general pixel array structure.

[0062] To further clarify the purpose, technical solutions, and advantages of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be described clearly and completely below with reference to the drawings of the embodiments of this disclosure. Of course, the embodiments described are only some, not all, embodiments of this disclosure. Any other embodiments that a person skilled in the art could obtain based on the embodiments of this disclosure without requiring inventive work are all within the scope of this disclosure.

[0063] Unless otherwise defined, technical or scientific terms used in this disclosure should have the ordinary meanings that are understandable to those skilled in the art. The terms “first,” “second,” and similar terms used in this disclosure do not indicate order, quantity, or importance, but are merely for distinguishing different components. Similar terms such as “equipment” or “includes” mean that the element or component listed before “equipment” or “includes” covers the element or component and its equivalent listed after “equipment” or “includes,” and does not exclude other elements or components. Similar terms such as “connection” or “linking” include electrical connections, whether direct or indirect, and are not limited to physical or mechanical connections.

[0064] To improve the resolution of organic light-emitting diode (OLED) displays, the currently commonly used method is sub-pixel rendering (SPR) technique, which allows different pixels to share at least one subpixel, thereby simulating with relatively small subpixels and achieving higher resolution.

[0065] In the field of organic light-emitting diode (OLED) displays, the human eye has different resolutions for red, green, and blue subpixels, and the brightness effects of these three subpixels also differ. The brightness effect of the green subpixel is the greatest, followed by the red subpixel, and the brightness effect of the blue subpixel is the smallest. At the same time, the lifespan of the organic light-emitting materials used in the organic light-emitting layers of different colored subpixels also differs. Therefore, in an OLED display device, the area of ​​the blue subpixel is larger than the area of ​​the green subpixel, and the area of ​​the green subpixel is larger than the area of ​​the red subpixel.

[0066] However, in typical pixel array structures, the brightness centers of virtual pixels are usually unevenly distributed, which affects display quality. Figure 1 is a schematic diagram of a pixel array structure. As shown in Figure 1, the pixel array structure includes red subpixels, green subpixels, and blue subpixels. The green subpixels are arranged along a first direction to form multiple rows of green subpixels, the red and blue subpixels are arranged alternately along the first direction to form rows of red and blue subpixels, and the rows of green and red and blue subpixels are arranged alternately along a second direction perpendicular to the first direction. In this pixel array structure, the red, green, and blue subpixels are all uniformly distributed, but because the human eye has different resolutions and sensitivities to red, green, and blue subpixels, the brightness centers of virtual pixels are not uniformly distributed to the human eye. For example, in a single virtual pixel, the luminance center of that pixel is located between the green subpixel and the red subpixel, and is close to the green subpixel. The distance between the luminance center of the virtual pixel in the j-th column and the luminance center of the virtual pixel in the (j+1)-th column is greater than the distance between the luminance center of the virtual pixel in the j-th column and the luminance center of the virtual pixel in the (j-1)-th column. Furthermore, the luminance centers of the virtual pixel in the i-th row and the luminance centers of the virtual pixel in the (i+1)-th row are offset from each other. Therefore, when a display device with such a pixel array structure and low resolution displays vertical lines or images mainly consisting of vertical lines, the human eye perceives a sense of distortion and graininess. Consequently, in organic light-emitting diode (OLED) display devices, the relative uniformity in the physical spatial arrangement of subpixels is not entirely equivalent to the uniformity of image display.

[0067] In contrast, embodiments of the present disclosure provide a pixel array structure comprising at least one array unit, the array unit comprising a first pixel row, a second pixel row, a third pixel row, and a fourth pixel row, wherein the first pixel row comprises a plurality of first subpixels arranged along a first direction, the second pixel row comprises a plurality of second subpixels and a plurality of third subpixels arranged along the first direction and alternately, the third pixel row comprises a plurality of first subpixels arranged along the first direction, and the fourth pixel row comprises a plurality of second subpixels and a plurality of third subpixels arranged along the first direction and alternately, the first pixel row, the second pixel row, the third pixel row, and the fourth pixel row are arranged along a second direction intersecting the first direction, and the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid. As a result, the pixel array structure can make the distribution of virtual pixels (or white dot pixels) more uniform by modulating the positions of subpixels of different colors. This solves display problems such as "distortion" and "graininess" caused by the human eye, and enables a superior display effect.

[0068] Embodiments of this disclosure further provide a display device including the above-described pixel array structure. This also enables the display device to have a more uniform distribution of virtual pixels (or white dot pixels), thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0069] The pixel array structure and display device provided by the embodiments of this disclosure will be described in detail below with reference to the drawings.

[0070] Embodiments of this disclosure provide a display substrate. Figure 2 is a schematic plan view of a display substrate provided by one embodiment of this disclosure, and Figure 3 is a schematic diagram of the distribution of luminance centers of virtual pixels of the display substrate provided by one embodiment of this disclosure. As shown in Figure 2, the display substrate 200 includes a base substrate 210 and a pixel array structure 100 located on the base substrate 210. Accordingly, embodiments of this disclosure also provide the pixel array structure 100.

[0071] As shown in Figure 2, the pixel array structure 100 includes at least one array unit 290, which includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124. The first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first subpixels are subpixels that emit light of a first color, the second subpixels are subpixels that emit light of a second color, and the third subpixels are subpixels that emit light of a third color.

[0072] As shown in Figure 2, the first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along the second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0073] In the pixel array structure provided by the embodiments of this disclosure, as shown in Figure 3, the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0074] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0075] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0076] For example, as shown in Figure 2, the smallest repeating unit of the pixel array structure 100 may include 16 first subpixels, 8 second subpixels, and 8 third subpixels.

[0077] In some examples, as shown in Figure 2, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light.

[0078] In some examples, as shown in Figure 2, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0079] For example, as shown in Figure 2, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 82° to 84°, for example, 83°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first subpixels, second subpixels, and third subpixels.

[0080] In some examples, as shown in Figure 2, the line connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 forms a virtual rectangle. As a result, the third subpixels of the pixel array structure are relatively uniform in physical spatial arrangement, and only the positions of the first and second subpixels need to be modulated to make the distribution of the luminance centers of the virtual pixels formed by the first, second, and third subpixels more uniform.

[0081] In some examples, as shown in Figure 2, the lines connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 form a virtual square. This makes the third subpixels of the pixel array structure more uniform in terms of physical spatial arrangement.

[0082] In some examples, as shown in Figure 2, the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 forms at least one of a virtual isosceles trapezoid, a virtual square, and a virtual quadrilateral. That is, the shape formed by the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 may be at least one of an isosceles trapezoid, a square, and a quadrilateral. This allows the pixel array structure to modulate the positions of the first and second subpixels, thereby making the distribution of the luminance centers of the virtual pixels formed by the first, second, and third subpixels more uniform.

[0083] For example, as shown in Figure 2, the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 can form three shapes, including an isosceles trapezoid, a square, and a quadrilateral, where the base angle of the isosceles trapezoid is 89° and the vertex angle is 91°, and the four interior angles of the quadrilateral are 88°, 92°, 88°, and 92°, respectively, meaning the virtual quadrilateral may also be a virtual parallelogram.

[0084] In some examples, as shown in Figure 2, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are placed opposite each other, and the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112. In other words, the shape of the second subpixel 112 is not axisymmetric. This allows the pixel array structure to reduce or avoid the occurrence of color separation by making the edges of the second corners more rounded. Furthermore, by installing a second subpixel having the above-mentioned first and second corners, the pixel array structure can flexibly adjust the size and distance of different subpixels, thereby achieving a better display effect. Note that the above-mentioned color indicators may be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the subpixel.

[0085] It should be noted that in the pixel array structure 100 shown in Figure 2, only the second subpixel has the above-mentioned asymmetric or oriented design. However, the embodiments of this disclosure are not limited thereto, and both the first and third subpixels may use the above-mentioned asymmetric or oriented design. Furthermore, the geometric center of the subpixel can tolerate a certain error or range. For example, the geometric center of the subpixel may be within a radius of 3 μm with the geometric center of the subpixel as the center of the circle.

[0086] In some cases, as shown in Figure 2, the curvature of the curve where the vertex of the first corner 112A is located is greater than the curvature of the curve where the vertex of the second corner 112B is located. This allows the pixel array structure to have rounder edges at the second corner, thereby reducing or avoiding the occurrence of color separation.

[0087] In some cases, as shown in Figure 2, the arc length of the outer edge of the first corner 112A is smaller than the arc length of the outer edge of the second corner 112B.

[0088] In some examples, as shown in Figure 2, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is different in the second pixel row 122 and the fourth pixel row 124, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution in the first direction of the second subpixels, thereby avoiding display defects. Note that the orientation mentioned above refers to the arrangement direction or order of the first and second corners.

[0089] In some examples, as shown in Figure 2, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is different in the second direction, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution of the second subpixels in the first and second directions, thereby improving display quality.

[0090] In some examples, as shown in Figure 2, each first subpixel 111 lies within the range of a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0091] In some examples, as shown in Figure 2, the first subpixel 111 has first distances L1 and L2 from two second subpixels 112 that form a virtual quadrilateral, and third distances L3 and L4 from two third subpixels 113 that form a virtual quadrilateral, with at least two of the first distance L1, second distance L2, third distance L3, and fourth distance L4 being equal. This allows the pixel array structure to fully utilize process precision and improve the aperture ratio of each subpixel.

[0092] In some examples, as shown in Figure 2, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all equal, i.e., L1 = L2 = L3 = L4.

[0093] In some examples, as shown in Figure 2, the first distance L1 is equal to the second distance L2, and the third distance L3 is not equal to the fourth distance L4; that is, L1=L2 and L3≠L4.

[0094] Of course, the embodiments of this disclosure are not limited thereto, and the first distance L1, second distance L2, third distance L3, and fourth distance L4 described above do not have to be equal.

[0095] In some examples, the geometric center of the first subpixel 111 is not located at the geometric center of the virtual quadrilateral formed by the lines connecting the centers of the two adjacent second subpixels 112 and the centers of the two third subpixels 113.

[0096] In some examples, as shown in Figure 2, multiple second subpixels 112 and multiple third subpixels 113 are arranged alternately along the second direction Y, forming a first pixel row 131. In the first pixel row 131, the angle between the line connecting the centers of two adjacent second subpixels 112 and third subpixels 113 and the second direction is in the range of 1° to 15°. This allows the pixel arrangement structure to make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0097] In some examples, as shown in Figure 2, in the first pixel row 131, the angle between the line connecting the centers of two adjacent second subpixels 112 and third subpixels 113 and the second direction is in the range of 5° to 7°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0098] In some examples, as shown in Figure 2, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 1° to 15°. This pixel arrangement structure allows for a more uniform distribution of virtual pixels (or white dot pixels) in the first direction, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a superior display effect.

[0099] In some examples, as shown in Figure 2, multiple first subpixels 111 are arranged along the second direction Y, forming a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 6° to 8°. This allows the pixel arrangement structure to further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0100] The shape of each subpixel can be limited to the opening of the pixel definition layer of the subpixel, and the shape of each subpixel is substantially the same as the shape of the corresponding opening of the pixel definition layer. Each subpixel includes a first electrode, a pixel definition layer, an emissive layer, and a second electrode, which are stacked together. When the emissive layer is formed within the opening of the pixel definition layer, the first and second electrodes located on either side of the emissive layer can drive the emissive layer within the opening of the pixel definition layer to emit light. For example, a functional layer is further installed between the emissive layer and the first electrode, and between the emissive layer and the second electrode, at least one of these locations. For example, the functional layer includes any one or more layers such as a hole injection layer, a hole transport layer, an electron transport layer, a hole blocking layer, an electron blocking layer, an electron injection layer, an auxiliary emissive layer, an interface improvement layer, and an anti-reflective layer.

[0101] In some examples, as shown in Figure 2, the pixel array structure 100 includes first subpixels 111, second subpixels 112, and third subpixels 113 configured to emit light of different colors, wherein the multiple first subpixels 111 are arranged along a first direction to form a first type of pixel row 121 or 123, the multiple second subpixels 112 and the multiple third subpixels 113 are arranged along the first direction and alternately arranged to form a second type of pixel row 122 or 124, the multiple first type of pixel row and the multiple second type of pixel row are arranged along a second direction intersecting the first direction, the lines connecting the centers of the four first subpixels 111 surrounding the third subpixel 113 form a virtual isosceles trapezoid, and the lines connecting the centers of the four second subpixels 112 surrounding the third subpixel 113 form a virtual quadrilateral.

[0102] In this pixel array structure, the lines connecting the centers of the four first subpixels surrounding the third subpixel form a virtual isosceles trapezoid, and the lines connecting the centers of the four second subpixels surrounding the third subpixel form a virtual quadrilateral. As a result, this pixel array structure can make the distribution of virtual pixels (or white dot pixels) more uniform by modulating the positions of subpixels of different colors, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a superior display effect.

[0103] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0104] In some cases, as shown in Figure 2, if the center of the third subpixel 113 is located at the intersection of the diagonals of a virtual isosceles trapezoid, the lines connecting the centers of the four second subpixels 112 surrounding the third subpixel 113 form a virtual isosceles trapezoid. If the center of the third subpixel 113 is not located at the intersection of the diagonals of a virtual isosceles trapezoid, the lines connecting the centers of the four second subpixels 112 surrounding the third subpixel 113 form a virtual parallelogram, virtual rectangle, or virtual square.

[0105] In some examples, as shown in Figure 2, the lines connecting the centers of the four third subpixels 113 surrounding the third subpixel 113 form a virtual rectangle.

[0106] In some examples, as shown in Figure 2, there are at least two possible arrangements for multiple third subpixels 113. In the first case, the center of a third subpixel 113 is located at the intersection of the diagonals of a virtual rectangle formed by lines connecting the centers of four third subpixels 113 surrounding it; that is, the center of at least one third subpixel 113 is located at the intersection of the diagonals of a virtual rectangle formed by lines connecting the centers of four third subpixels 113 surrounding it. In the second case, the center of a third subpixel 113 is not located at the intersection of the diagonals of a virtual rectangle formed by lines connecting the centers of four third subpixels 113 surrounding it; that is, the center of a third subpixel 113 is not located at the intersection of the diagonals of a virtual rectangle formed by lines connecting the centers of four third subpixels 113 surrounding it.

[0107] In some examples, as shown in Figure 2, in the second direction, multiple adjacent third subpixels 113 are spaced apart along the second direction by third and fourth intervals, with the size of the third interval in the second direction being smaller than the size of the fourth interval in the second direction.

[0108] Figure 4 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 4, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0109] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0110] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0111] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0112] For example, as shown in Figure 4, the smallest repeating unit of the pixel array structure 100 may include 16 first subpixels, 8 second subpixels, and 8 third subpixels.

[0113] In some examples, as shown in Figure 4, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light.

[0114] In some examples, as shown in Figure 4, in the first pixel row 121, multiple first subpixels 111 are arranged with a first interval S1 and a second interval S2 along the first direction, where the first interval S1 is smaller than the second interval S2, and the first interval S1 and the second interval S2 are alternated, meaning that in the first direction, the distance between adjacent first subpixels 111 is not equal, and there are two interval distances, the first interval S1 and the second interval S2. In this case, in order to make full use of process accuracy (e.g., manufacturing accuracy of the fine metal mask) and improve the pixel aperture ratio, the two opposing corners of the two first subpixels 111 on either side of the first interval can be chamfered to form a first chamfered portion, thereby widening the width of the first interval and reducing the difference between the first and second intervals.

[0115] For example, as shown in Figure 4, the curvature of the outer edge of the first chamfered portion is smaller than the curvature of the outer edge of the unchamfered corner of the first subpixel 111.

[0116] In some examples, as shown in Figure 4, the shape of the first subpixel 111 is elongated, thereby having an extending direction, and the angle between the extending direction of the first subpixel 111 and the first or second direction is in the range of 30° to 60°.

[0117] In some examples, as shown in Figure 4, the extension directions of two adjacent first subpixels 111 in the first direction are symmetrically positioned with respect to the second direction; that is, two adjacent first pixels in the first direction are symmetrically positioned with respect to the second direction.

[0118] In some examples, as shown in Figure 4, the first subpixel 111 is chamfered, so that the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 84° to 86°, for example, 85°. This allows the pixel array structure to have a more uniform distribution of the luminance centers of the virtual pixels formed by the first subpixel, second subpixel, and third subpixel.

[0119] In some examples, as shown in Figure 4, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are placed opposite each other, and the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112. In other words, the shape of the second subpixel 112 is not axisymmetric. This allows the pixel array structure to reduce or avoid the occurrence of color separation by making the edges of the second corners more rounded. Furthermore, by installing a second subpixel having the first and second corners described above, the pixel array structure can flexibly adjust the size and distance of different subpixels, thereby achieving a better display effect. Note that the above color indicators may be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the subpixel.

[0120] In some cases, as shown in Figure 4, the curvature of the curve where the vertex of the first corner 112A is located is greater than the curvature of the curve where the vertex of the second corner 112B is located. This allows the pixel array structure to have rounder edges at the second corner, thereby reducing or avoiding the occurrence of color separation.

[0121] In some examples, as shown in Figure 4, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is different in the second pixel row 122 and the fourth pixel row 124, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution in the first direction of the second subpixels, thereby avoiding display defects. The orientation mentioned above refers to the arrangement direction or order of the first and second corners.

[0122] In some examples, as shown in Figure 4, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is different in the second direction, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution of the second subpixels in the first and second directions, thereby improving display quality.

[0123] Figure 5 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 5, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0124] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0125] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0126] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0127] In some examples, as shown in Figure 5, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light.

[0128] In some examples, as shown in Figure 5, in the first pixel row 121, multiple first subpixels 111 are spaced apart along the first direction by a first interval S1 and a second interval S2, where the first interval S1 is smaller than the second interval S2, and the first interval S1 and the second interval S2 are alternated, meaning that in the first direction, the distance between adjacent first subpixels 111 is not equal, and there are two spacing distances, the first interval S1 and the second interval S2. In this case, in order to fully utilize process accuracy (e.g., manufacturing accuracy of the fine metal mask) and improve the pixel aperture ratio, the two opposing corners of the two first subpixels 111 on either side of the first interval can be chamfered to form a first chamfered portion.

[0129] For example, as shown in Figure 5, the curvature of the outer edge of the first chamfered portion is smaller than the curvature of the outer edge of the unchamfered corner of the first subpixel 111.

[0130] In some examples, as shown in Figure 5, the two opposing corners of the two first subpixels 111 on either side of the second interval S2 may be chamfered to form a second chamfered portion. This allows the pixel array structure to make better use of process precision (e.g., the manufacturing precision of the fine metal mask) and improve the pixel aperture ratio. The shape of the first subpixels also becomes more symmetrical.

[0131] For example, as shown in Figure 5, the curvature of the outer edge of the second chamfered portion is smaller than the curvature of the outer edge of the unchamfered corner of the first subpixel 111.

[0132] Figure 6 is a schematic plan view of another display board provided by an embodiment of the present disclosure, and Figure 7 is a schematic view of the luminance centers of virtual pixels of the display board provided by an embodiment of the present disclosure. As shown in Figure 6, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0133] In the pixel array structure provided by the embodiments of this disclosure, as shown in Figure 7, the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0134] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0135] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0136] In some examples, as shown in Figure 6, the smallest repeating unit of the pixel array structure 100 includes four first subpixels, two second subpixels, and two third subpixels.

[0137] In some examples, as shown in Figure 6, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0138] In some examples, as shown in Figure 6, multiple second subpixels 112 and multiple third subpixels 113 are arranged alternately along the second direction Y to form the first pixel row 131.

[0139] In some examples, as shown in Figure 6, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are positioned opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, and in the first pixel row 131, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned opposite each other in the second direction. In other words, in this pixel array structure, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned in the second direction, i.e., the second subpixel 112 is oriented in the second direction, thereby reducing the difficulty of manufacturing the corresponding mask plate. Of course, the embodiments of this disclosure are not limited thereto, and the first corner 112A and the second corner 112B of the second subpixel 112 may be positioned opposite each other in the first direction.

[0140] For example, as shown in Figure 6, the first corner 112A of the second subpixel 112 is located above the second corner 112B, meaning that the second subpixel 112 is oriented upward.

[0141] In some cases, as shown in Figure 6, the curvature of the curve where the vertex of the first corner 112A is located is greater than the curvature of the curve where the vertex of the second corner 112B is located. This allows the pixel array structure to have rounder edges at the second corner, thereby reducing or avoiding the occurrence of color separation.

[0142] In some examples, as shown in Figure 6, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0143] For example, as shown in Figure 6, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 82° to 84°, for example, 83°. This makes the pixel array structure more uniform in terms of the distribution of luminance centers of the virtual pixels formed by the first subpixel, second subpixel, and third subpixel.

[0144] In some examples, as shown in Figure 6, the line connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 forms a virtual square. As a result, the third subpixels of the pixel array structure are relatively uniform in physical spatial arrangement, and only the positions of the first and second subpixels need to be modulated to make the distribution of the luminance centers of the virtual pixels formed by the first, second, and third subpixels more uniform.

[0145] In some examples, as shown in Figure 6, the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 forms a virtual square. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, simply by modulating the position of the first subpixel.

[0146] In some examples, as shown in Figure 6, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same in the second pixel row 122 and the fourth pixel row 124. In the second direction, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same. This pixel arrangement structure can reduce the difficulty of manufacturing the mask plate for the second subpixels.

[0147] In some examples, as shown in Figure 6, each first subpixel 111 lies within a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0148] In some cases, as shown in Figure 6, the line connecting the centers of two adjacent second subpixels 112 and third subpixels 113 is parallel to the second direction in the second direction.

[0149] In some examples, as shown in Figure 6, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 1° to 10°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0150] In some examples, as shown in Figure 6, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 5° to 9°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0151] In some examples, as shown in Figure 6, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 7° to 9°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0152] In some examples, as shown in Figure 6, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 1° to 15°. This pixel arrangement structure allows for a more uniform distribution of virtual pixels (or white dot pixels) in the first direction, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0153] In some examples, as shown in Figure 6, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 6° to 8°. This allows the pixel arrangement structure to further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0154] In some examples, as shown in Figure 6, the first subpixel 111 has first distances L1 and L2 from two second subpixels 112 that form a virtual quadrilateral, and third distances L3 and L4 from two third subpixels 113 that form a virtual quadrilateral, and at least two of the first distance L1, second distance L2, third distance L3 and fourth distance L4 are equal. This allows the pixel array structure to fully utilize process precision and improve the aperture ratio of each subpixel.

[0155] In some examples, as shown in Figure 6, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all equal, i.e., L1 = L2 = L3 = L4.

[0156] In some examples, as shown in Figure 6, the first distance L1 is equal to the second distance L2, and the third distance L3 is not equal to the fourth distance L4; that is, L1=L2 and L3≠L4.

[0157] Of course, the embodiments of this disclosure are not limited thereto, and the first distance L1, second distance L2, third distance L3, and fourth distance L4 described above do not have to be equal.

[0158] In some examples, the geometric center of the first subpixel 111 is not located at the geometric center of the virtual quadrilateral formed by the lines connecting the centers of the two adjacent second subpixels 112 and the centers of the two third subpixels 113.

[0159] Figure 8 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 8, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0160] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0161] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0162] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0163] In some examples, as shown in Figure 8, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0164] In some examples, as shown in Figure 8, multiple second subpixels 112 and multiple third subpixels 113 are arranged alternately along the second direction Y to form the first pixel row 131.

[0165] In some examples, as shown in Figure 8, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are positioned opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, and in the first pixel row 131, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned opposite each other in the second direction. In other words, in this pixel array structure, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned in the second direction, i.e., the second subpixel 112 is oriented in the second direction, thereby reducing the difficulty of manufacturing the corresponding mask plate.

[0166] For example, as shown in Figure 8, the first corner 112A of the second subpixel 112 is located below the second corner 112B, meaning that the second subpixel 112 is oriented downwards.

[0167] In some examples, as shown in Figure 8, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same in the second pixel row 122 and the fourth pixel row 124. In the second direction, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same. This pixel arrangement structure can reduce the difficulty of manufacturing the mask plate for the second subpixels.

[0168] In some examples, as shown in Figure 8, each first subpixel 111 lies within a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0169] In some cases, as shown in Figure 8, the line connecting the centers of two adjacent second subpixels 112 and third subpixels 113 in the second direction is parallel to the second direction.

[0170] In some examples, as shown in Figure 8, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 1° to 10°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0171] In some examples, as shown in Figure 8, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 5° to 7°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0172] In some examples, as shown in Figure 8, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 1° to 15°. This pixel arrangement structure allows for a more uniform distribution of virtual pixels (or white dot pixels) in the first direction, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0173] In some examples, as shown in Figure 8, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 6° to 8°. This allows the pixel arrangement structure to further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0174] Figure 9 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 9, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0175] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0176] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0177] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0178] In some examples, as shown in Figure 9, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0179] In some examples, as shown in Figure 9, multiple second subpixels 112 and multiple third subpixels 113 are arranged alternately along the second direction Y to form the first pixel row 131.

[0180] In some examples, as shown in Figure 9, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are positioned opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, and in the first pixel row 131, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned opposite each other in the first direction. In other words, in this pixel array structure, the first corner 112A and the second corner 112B of the second subpixel 112 are positioned in the first direction, i.e., the second subpixel 112 is oriented in the first direction, thereby reducing the difficulty of manufacturing the corresponding mask plate.

[0181] For example, as shown in Figure 9, the first corner 112A of the second subpixel 112 is located to the right of the second corner 112B, meaning that the second subpixel 112 is oriented to the right.

[0182] In some examples, as shown in Figure 9, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same in the second pixel row 122 and the fourth pixel row 124. In the second direction, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same. This pixel arrangement structure can reduce the difficulty of manufacturing the mask plate for the second subpixels.

[0183] In some examples, as shown in Figure 9, each first subpixel 111 lies within the range of a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0184] In some examples, as shown in Figure 9, the angle between the line connecting the centers of two adjacent second subpixels 112 and third subpixels 113 in the second direction and the second direction is in the range of 1° to 15°, for example, 1°.

[0185] In some examples, as shown in Figure 9, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 1° to 15°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0186] In some examples, as shown in Figure 9, in the second pixel row 122 or the fourth pixel row 124, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the first direction is in the range of 6° to 8°. This allows the pixel array structure to further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0187] In some examples, as shown in Figure 9, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 1° to 15°. This allows the pixel arrangement structure to make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0188] In some examples, as shown in Figure 9, multiple first subpixels 111 are arranged along the second direction Y to form a second pixel row 132, where the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 6° to 8°. This allows the pixel arrangement structure to further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0189] Figure 10 is a schematic plan view of another display board provided by an embodiment of the present disclosure, and Figure 11 is a schematic diagram of the distribution of luminance centers of virtual pixels of another display board provided by an embodiment of the present disclosure. As shown in Figure 10, the display board 200 includes a pixel array structure 100. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0190] In the pixel array structure provided by the embodiments of this disclosure, as shown in Figure 11, the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0191] Furthermore, as shown in Figure 11, there are three states for the luminance centers of virtual pixels in the pixel array structure 100: the first state is the distribution of luminance centers of virtual pixels in odd-numbered rows; the second state is the distribution of luminance centers of virtual pixels in even-numbered rows and odd-numbered columns; and the third state is the distribution of luminance centers of virtual pixels in even-numbered rows and even-numbered columns. This allows the pixel array structure to be modulated more appropriately by utilizing various luminance distribution states of virtual pixels, thereby increasing the uniformity of white point luminance across the entire screen. Additionally, when using the pixel borrowing algorithm, if there are two or more second and third subpixels borrowed by the first subpixel, the uniformity of white point luminance across the entire screen can be achieved more effectively by utilizing various luminance distribution states of virtual pixels.

[0192] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0193] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0194] In some examples, as shown in Figure 10, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0195] In some examples, as shown in Figure 10, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B placed opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, and in the second pixel row 122 and the fourth pixel row 124, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is the same, that is, the orientation of two adjacent second subpixels 112 is the same. Note that since the distance between the vertex of the first corner and the geometric center of the second subpixel is greater than the distance between the vertex of the second corner and the geometric center of the second subpixel, the second subpixel is oriented in the arrangement direction of the first and second corners.

[0196] In some examples, as shown in Figure 10, the alignment directions of the first corner 112A and the second corner 112B of the second subpixel 112 in the second pixel row 122 are orthogonal to each other with the alignment directions of the first corner 112A and the second corner 112B of the second subpixel 112 in the fourth pixel row 124. As a result, the second subpixel in the pixel arrangement structure has two mutually orthogonal directions.

[0197] For example, as shown in Figure 10, in the first direction, both adjacent second subpixels 112 are oriented to the left, that is, the first corner 112A is located to the left of the second corner 112B, and in the second direction, both adjacent second subpixels 112 are oriented upward, that is, the first corner 112A is located above the second corner 112B.

[0198] In some examples, as shown in Figure 10, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "granularity" caused by the human eye.

[0199] For example, as shown in Figure 10, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 82° to 84°, for example, 83°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first subpixels, second subpixels, and third subpixels.

[0200] In some examples, as shown in Figure 10, the line connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 forms a virtual square. As a result, the third subpixels of the pixel array structure are relatively uniform in physical spatial arrangement, and only the positions of the first and second subpixels need to be modulated to make the distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels more uniform.

[0201] In some examples, as shown in Figure 10, the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 forms a virtual isosceles trapezoid. This allows the pixel array structure to modulate the positions of the first and second subpixels, thereby making the distribution of the luminance centers of the virtual pixels formed by the first, second, and third subpixels more uniform.

[0202] In some examples, as shown in Figure 10, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "granularity" caused by the human eye.

[0203] In some examples, as shown in Figure 10, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 1° to 15°, and in the second direction, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the second direction is in the range of 1° to 15°.

[0204] In some examples, as shown in Figure 10, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 6° to 8°.

[0205] In some examples, as shown in Figure 10, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the second direction may be 1°.

[0206] In some examples, as shown in Figure 10, multiple second subpixels 112 and multiple third subpixels 113 are arranged alternately along the second direction Y to form the first pixel row 131, and multiple first subpixels 111 are arranged along the second direction Y to form the second pixel row 132. In the second pixel row 132, the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 1° to 15°. This allows the pixel arrangement structure to make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0207] In some examples, as shown in Figure 10, in the second pixel row 132, the angle between the line connecting the centers of two adjacent first subpixels 111 and the second direction is in the range of 6° to 8°, for example, 7°. This further allows the pixel array structure to make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0208] In some examples, as shown in Figure 10, each first subpixel 111 lies within the range of a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0209] In some examples, as shown in Figure 10, the first subpixel 111 has first distances L1 and L2 from two second subpixels 112 that form a virtual quadrilateral, and third distances L3 and L4 from two third subpixels 113 that form a virtual quadrilateral, and at least two of the first distance L1, second distance L2, third distance L3 and fourth distance L4 are equal. This allows the pixel array structure to fully utilize process precision and improve the aperture ratio of each subpixel.

[0210] In some examples, as shown in Figure 10, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all equal, i.e., L1 = L2 = L3 = L4.

[0211] In some examples, as shown in Figure 10, the first distance L1 is equal to the second distance L2, and the third distance L3 is not equal to the fourth distance L4, that is, L1=L2 and L3≠L4.

[0212] Of course, the embodiments of this disclosure are not limited thereto, and the first distance L1, second distance L2, third distance L3, and fourth distance L4 described above do not have to be equal.

[0213] In some examples, the geometric center of the first subpixel 111 is not located at the geometric center of the virtual quadrilateral formed by the lines connecting the centers of the two adjacent second subpixels 112 and the centers of the two third subpixels 113.

[0214] Figure 12 is a schematic plan view of another display substrate provided by one embodiment of the present disclosure. As shown in Figure 12, the display substrate 200 includes a pixel array structure 100. Unlike the display substrate shown in Figure 10, in the first direction, two adjacent second subpixels 112 are both oriented to the left, i.e., the first corner 112A is located to the left of the second corner 112B, and in the second direction, two adjacent second subpixels 112 are both oriented downward, i.e., the second corner 112A is located above the second corner 112B. In other words, if the alignment direction of the first corner 112A and the second corner 112B of the second subpixel 112 in the second pixel row 122 is orthogonal to the alignment direction of the first corner 112A and the second corner 112B of the second subpixel 112 in the fourth pixel row 124, then the second subpixel 112 in the second pixel row 122 is oriented to the left or right, and the second subpixel 112 in the fourth pixel row 124 is oriented upward or downward.

[0215] Figure 13 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 13, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0216] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0217] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0218] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0219] In some examples, as shown in Figure 13, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0220] In some examples, as shown in Figure 13, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B placed opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, the arrangement order of the first corner 112A and second corner 112B of two adjacent second subpixels 112 is the same in the second pixel row 122 and the fourth pixel row 124, the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the second pixel row 122 is opposite to the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the fourth pixel row 124.

[0221] In some examples, as shown in Figure 13, the first corner 112A of the second subpixel 112 in the second pixel row 122 is located below the second corner 112B, and the first corner 112A of the second subpixel 112 in the fourth pixel row 124 is located above the second corner 112B.

[0222] In some examples, as shown in Figure 13, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 1° to 15°, and in the second direction, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the second direction is in the range of 1° to 15°.

[0223] In some examples, as shown in Figure 13, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 7° to 8°, for example, 8°.

[0224] Figure 14 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 14, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. Unlike the display board shown in Figure 13, in the pixel array structure shown in Figure 14, the first corner 112A of the second subpixel 112 in the second pixel row 122 is located to the right of the second corner 112B, and the first corner 112A of the second subpixel 112 in the fourth pixel row 124 is located to the left of the second corner 112B.

[0225] In some examples, as shown in Figure 14, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 7° to 8°, for example, 7°.

[0226] In some examples, as shown in Figure 14, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second direction and the second direction is in the range of 1° to 3°, for example, 1°.

[0227] Figure 15 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 15, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. Unlike the display board shown in Figure 13, in the pixel array structure shown in Figure 15, the first corner 112A of the second subpixel 112 in the second pixel row 122 is located to the left of the second corner 112B, and the first corner 112A of the second subpixel 112 in the fourth pixel row 124 is located to the right of the second corner 112B.

[0228] Figure 16 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 16, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0229] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0230] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0231] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0232] In some examples, as shown in Figure 16, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0233] In some examples, as shown in Figure 16, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B placed opposite each other, the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112, the arrangement order of the first corner 112A and second corner 112B of two adjacent second subpixels 112 is the same in the second pixel row 122 and the fourth pixel row 124, the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the second pixel row 122 is orthogonal to the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the fourth pixel row 124, and in the second direction, the arrangement order of the first corner 112A and second corner 112B of two adjacent second subpixels 112 is different, for example, the arrangement order is reversed. In other words, the second subpixel 112 has three directions, two of which are parallel, and the other one is perpendicular to these two directions.

[0234] In some examples, as shown in Figure 16, the lines connecting the centers of two third subpixels 113 in the second pixel row 122 and the centers of two third subpixels 113 in the fourth pixel row 124 can form a virtual square. The lines connecting the centers of two second subpixels 112 in the second pixel row 122 and the centers of two second subpixels 112 in the fourth pixel row 124 can form a virtual isosceles trapezoid.

[0235] In some examples, as shown in Figure 16, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0236] In some examples, as shown in Figure 16, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0237] In some examples, as shown in Figure 16, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 1° to 15°, and in the second direction, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the second direction is in the range of 1° to 15°.

[0238] In some examples, as shown in Figure 16, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 1° to 3°, and the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 in the second pixel row 122 and fourth pixel row 124 and the first direction is in the range of 5° to 7°.

[0239] In some examples, as shown in Figure 16, in a pixel row where the first corner 112A of the second subpixel 112 is located above the second corner 112, the angle between the line connecting the centers of adjacent second subpixels 112 and third subpixels 113 and the second direction may be 1°.

[0240] In some examples, as shown in Figure 16, each first subpixel 111 lies within a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0241] In some examples, as shown in Figure 16, the first subpixel 111 has first distances L1 and L2 from two second subpixels 112 that form a virtual quadrilateral, and third distances L3 and L4 from two third subpixels 113 that form a virtual quadrilateral, with at least two of the first distance L1, second distance L2, third distance L3, and fourth distance L4 being equal. This allows the pixel array structure to fully utilize process precision and improve the aperture ratio of each subpixel.

[0242] In some examples, as shown in Figure 16, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all equal, i.e., L1 = L2 = L3 = L4.

[0243] In some examples, as shown in Figure 16, the first distance L1 is equal to the second distance L2, and the third distance L3 is not equal to the fourth distance L4; that is, L1=L2 and L3≠L4.

[0244] Of course, the embodiments of this disclosure are not limited thereto, and the first distance L1, second distance L2, third distance L3, and fourth distance L4 described above do not have to be equal.

[0245] In some examples, the geometric center of the first subpixel 111 is not located at the geometric center of the virtual quadrilateral formed by the lines connecting the centers of the two adjacent second subpixels 112 and the centers of the two third subpixels 113.

[0246] Figure 17 is a schematic plan view of another display board provided by an embodiment of the present disclosure. As shown in Figure 17, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. Unlike the display board shown in Figure 16, in the pixel array structure shown in Figure 17, in the second pixel row 122 and the fourth pixel row 124, the arrangement order of the first corner 112A and second corner 112B of two adjacent second subpixels 112 is different, for example, the arrangement order is reversed, the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the second pixel row 122 is orthogonal to each other with respect to the arrangement direction of the first corner 112A and second corner 112B of the second subpixel 112 in the fourth pixel row 124, and in the second direction, the arrangement order of the first corner 112A and second corner 112B of two adjacent second subpixels 112 is the same.

[0247] Figure 18 is a schematic diagram of three shapes of a second subpixel provided in one embodiment of the present disclosure, Figure 19 is a schematic plan view of another display substrate provided in one embodiment of the present disclosure, and Figure 20 is a schematic plan view of another display substrate provided in one embodiment of the present disclosure. As shown in Figures 19 to 20, the display substrate 200 includes a base substrate 210 and a pixel array structure 100 located on the base substrate 210. The pixel array structure 100 includes at least one array unit 290, which includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0248] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0249] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0250] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0251] In some examples, as shown in Figures 19 to 20, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light. Of course, embodiments of this disclosure are not limited thereto, and the colors of light emitted by the second and third subpixels are interchangeable, i.e., the second subpixel is configured to emit red light and the third subpixel is configured to emit blue light.

[0252] In some examples, as shown in Figure 18, the shape of the second subpixel 112 includes at least one of the first shape 1121, the second shape 1122, and the third shape 1123, where the first shape 1121 includes a first corner 1121A and a second corner 1121B placed opposite each other, the distance between the vertex of the first corner 1121A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 1121B and the geometric center of the second subpixel 112, the second shape 1122 includes a third corner 1122A and a flat section 1122B placed opposite each other, the edge of the flat section 1122B away from the third corner 1122A is a straight line, and the third shape Shape 1123 includes a fourth corner 1123A and a fifth corner 1134B that are positioned opposite each other in the first direction, and a sixth corner 1123C and a seventh corner 1123D that are positioned opposite each other in the second direction. The distance between the vertex of the fourth corner 1123A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the fifth corner 1123B and the geometric center of the second sub-pixel 112, and the distance between the vertex of the sixth corner 1123C and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the seventh corner 1123D and the geometric center of the second sub-pixel 112. The fifth corner 1123B and the seventh corner 1123D are positioned adjacent to each other.

[0253] In some examples, as shown in Figure 19, the shape of the second subpixel 112 in the pixel array structure 100 is the second shape. In the second pixel row 122 and the fourth pixel row 124, the orientation of two adjacent second subpixels 112 is the same, and in the second direction, the orientation of two adjacent second subpixels 112 is the same.

[0254] In some examples, as shown in Figure 20, the shape of the second subpixel 112 in the pixel array structure includes a second shape and a first shape.

[0255] In some cases, as shown in Figure 20, the shape of the second subpixel 112 in the second pixel row 122 differs from the shape of the second subpixel 112 in the fourth pixel row 124. For example, the shape of the second subpixel 112 in the second pixel row 122 is the first shape, and the shape of the second subpixel 112 in the fourth pixel row 124 is the second shape.

[0256] In the embodiments of this disclosure, if the shape of the second subpixel 112 includes at least one of the first, second, and third shapes described above, the pixel array structure may use any one of the three second subpixels having the three shapes described above, or a combination of at least two of them, which will not be repeated here.

[0257] Figure 21 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 21, the display board 200 includes a base board 210 and a pixel array structure 100 located on the base board 210. The pixel array structure 100 includes at least one array unit 290, the array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124, wherein the first pixel row 121 includes a plurality of first subpixels 111 arranged along a first direction X, the second pixel row 122 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately, the third pixel row 123 includes a plurality of first subpixels 111 arranged along a first direction X, and the fourth pixel row 124 includes a plurality of second subpixels 112 and a plurality of third subpixels 113 arranged along a first direction X and alternately. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X, and the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0258] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0259] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0260] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0261] In some examples, as shown in Figure 21, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light.

[0262] In some examples, as shown in Figure 21, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0263] For example, as shown in Figure 21, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 86° to 88°, for example, 87°. This makes the pixel array structure more uniform in the distribution of the luminance centers of the virtual pixels formed by the first subpixel, second subpixel, and third subpixel.

[0264] In some examples, as shown in Figure 21, the lines connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 112 in the fourth pixel row 124 form a virtual square.

[0265] In some examples, as shown in Figure 21, the lines connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 form a virtual quadrilateral.

[0266] For example, as shown in Figure 21, the four interior angles of the virtual quadrilateral formed by the lines connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 are 83°, 90°, 97°, and 90°, respectively.

[0267] In some examples, as shown in Figure 21, the shapes of the first subpixel 111, the second subpixel 112, and the third subpixel 113 are all rectangles or rounded rectangles. A rounded rectangle refers to a rectangle in which all four corners have been rounded.

[0268] In some examples, as shown in Figure 21, each first subpixel 111 lies within the range of a virtual quadrilateral formed by lines connecting the centers of two adjacent second subpixels 112 and the centers of two third subpixels 113. That is, each first subpixel 111 is surrounded by two adjacent second subpixels 112 and two third subpixels 113. This allows the pixel array structure to more effectively implement pixel borrowing and achieve high display quality.

[0269] In some examples, as shown in Figure 21, the first subpixel 111 has first distances L1 and L2 from two second subpixels 112 that form a virtual quadrilateral, and third distances L3 and L4 from two third subpixels 113 that form a virtual quadrilateral, with at least two of the first distance L1, second distance L2, third distance L3, and fourth distance L4 being equal. This allows the pixel array structure to fully utilize process precision and improve the aperture ratio of each subpixel.

[0270] In some examples, as shown in Figure 21, the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are all equal, i.e., L1 = L2 = L3 = L4.

[0271] In some examples, as shown in Figure 21, the first distance L1 is equal to the second distance L2, and the third distance L3 is not equal to the fourth distance L4, i.e., L1=L2 and L3≠L4.

[0272] Of course, the embodiments of this disclosure are not limited thereto, and the first distance L1, second distance L2, third distance L3, and fourth distance L4 described above do not have to be equal.

[0273] In some examples, the geometric center of the first subpixel 111 is not located at the geometric center of the virtual quadrilateral formed by the lines connecting the centers of the two adjacent second subpixels 112 and the centers of the two third subpixels 113.

[0274] In some examples, as shown in FIG. 21, a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along a second direction to form a first pixel column, and a plurality of first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. In the second pixel column 132, the included angle between the line connecting the centers of two adjacent first sub-pixels 111 and the second direction is in the range of 1° to 15°. Thereby, the pixel array structure can make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion feeling" and "granularity feeling" caused by the human eye, and realizing a better display effect.

[0275] In some examples, as shown in FIG. 21, the included angle between the line connecting the centers of two adjacent first sub-pixels 111 and the second direction is in the range of 2° to 4°, for example, 3°. Thereby, the pixel array structure can further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby solving display problems such as "distortion feeling" and "granularity feeling" caused by the human eye, and realizing a better display effect.

[0276] In some examples, as shown in FIG. 21, in the first pixel row 121 and the third pixel row 123, the line connecting the centers of two adjacent first sub-pixels 111 is parallel to the first direction.

[0277] In some examples, as shown in FIG. 21, in the second pixel row 122 and the fourth pixel row 124, the included angle between the line connecting the centers of adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction is in the range of 1° to 15°. Thereby, the pixel array structure can make the distribution of virtual pixels (or white dot pixels) more uniform, thereby solving display problems such as "distortion feeling" and "granularity feeling" caused by the human eye, and realizing a better display effect.

[0278] In some examples, as shown in FIG. 21, in the second pixel row 122 and the fourth pixel row 124, the included angle between the line connecting the centers of adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction is in the range of 6° to 8°, for example, 7°. Thereby, the pixel array structure can make the distribution of virtual pixels (or white dot pixels) more uniform, thereby solving display problems such as "distortion feeling" and "granularity feeling" caused by the human eye, and realizing a better display effect.

[0279] FIG. 22 is a schematic plan view of another display substrate provided according to an embodiment of the present disclosure. As shown in FIG. 22, the display substrate 200 includes a base substrate 210 and a pixel array structure 100 located on the base substrate 210. The pixel array structure 100 includes at least one array unit 290. The array unit 290 includes a first pixel row 121, a second pixel row 122, a third pixel row 123, and a fourth pixel row 124. The first pixel row 121 includes a plurality of first sub-pixels 111 arranged along the first direction X. The second pixel row 122 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged along the first direction X and alternately installed. The third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X. The fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged along the first direction X and alternately installed. The first pixel row 121, the second pixel row 122, the third pixel row 123, and the fourth pixel row 124 are arranged along a second direction Y intersecting the first direction X. The line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and the centers of two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0280] In the pixel array structure provided by the embodiments of this disclosure, the line connecting the centers of two adjacent first subpixels in the first pixel row and the centers of two adjacent first subpixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. This allows the pixel array structure to modulate the positions of subpixels of different colors, thereby making the distribution of virtual pixels (or white dot pixels) more uniform. This solves display problems such as "distortion" and "granularity" caused by the human eye, and enables a superior display effect.

[0281] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0282] For example, the above array unit may be the smallest repeating unit of the pixel array structure, and by being repeatedly arranged in a first and second direction, the entire display substrate can be covered. Of course, the embodiments of this disclosure are not limited thereto, and the above array unit may be larger than the smallest repeating unit or smaller than the smallest repeating unit.

[0283] In some examples, as shown in Figure 22, the first subpixel 111 is configured to emit green light, the second subpixel 112 is configured to emit blue light, and the third subpixel 113 is configured to emit red light.

[0284] In some examples, as shown in Figure 22, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 75° to 90°. This allows the pixel array structure to have a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third subpixels, thereby better resolving display problems such as "distortion" and "graininess" caused by the human eye.

[0285] For example, as shown in Figure 22, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first subpixels 111 in the first pixel row 121 and the centers of two adjacent first subpixels 111 in the third pixel row 123 is in the range of 86° to 88°, for example, 87°. This makes the pixel array structure more uniform in the distribution of the luminance centers of the virtual pixels formed by the first subpixel, second subpixel, and third subpixel.

[0286] In some examples, as shown in Figure 22, the lines connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 form a virtual quadrilateral.

[0287] For example, as shown in Figure 22, the four interior angles of the virtual quadrilateral formed by the lines connecting the centers of two adjacent third subpixels 113 in the second pixel row 122 and the centers of two adjacent third subpixels 113 in the fourth pixel row 124 are 83°, 90°, 97°, and 90°, respectively.

[0288] In some examples, as shown in Figure 22, the line connecting the centers of two adjacent second subpixels 112 in the second pixel row 122 and the centers of two adjacent second subpixels 122 in the fourth pixel row 124 forms at least one of a virtual isosceles trapezoid, a virtual square, and a virtual parallelogram.

[0289] In some examples, as shown in Figure 22, each first subpixel 111 lies within the range of a virtual trapezoid formed by lines connecting the centers of two adjacent second subpixels 112 and two third subpixels 113.

[0290] At least one embodiment of the present disclosure further provides a display device. Figure 23 is a schematic diagram of a display device provided by one embodiment of the present disclosure. As shown in Figure 23, the display device 500 includes the pixel array structure 100 described above. This also allows the display device to have a more uniform distribution of virtual pixels (or white dot pixels), thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a better display effect.

[0291] For example, the display device may be an electronic product with a display function, such as a smartphone, television, computer, tablet PC, navigation system, car central control screen, or smartwatch.

[0292] At least one embodiment of the present disclosure further provides a schematic plan view of a subpixel on another display substrate. Figure 24 is a schematic plan view of another subpixel provided by one embodiment of the present disclosure, and as shown in Figure 24, the second subpixel 112 includes a first corner 112A and a second corner 112A, and the distance from the intersection of the extensions of the two straight sides L1 and L2 constituting the first corner 112A to the center O of the subpixel is different from the distance from the intersection of the two straight sides L3 and L4 constituting the second corner 112B to the center O of the subpixel. Although Figure 24 describes and explains the shape of a subpixel using the second subpixel as an example, embodiments of the present disclosure are not limited to the second subpixel using the above shape, and both the first and third subpixels can use the above shape.

[0293] In the display substrate provided by the embodiments of this disclosure, the actual luminance center of each virtual pixel unit is adjusted by making the distance from the intersection of the extensions of the two straight edges constituting the first corner to the center of the subpixel different from the distance from the intersection of the two straight edges constituting the second corner or their extensions to the center of the subpixel, thereby making the distribution of the actual luminance centers of each virtual pixel in the pixel array structure or display substrate more uniform.

[0294] In some examples, as shown in Figure 24, the second subpixel 112 further includes a third corner 112C and a square corner 112D that are positioned opposite each other, and the line connecting the vertices of the third corner 112C and the square corner 112D divides the second subpixel into two parts of different shapes, and the area of ​​the part where the second corner 112B is located is smaller than the area of ​​the part where the first corner 112A is located.

[0295] For example, as shown in Figure 24, the line connecting the vertex of the third corner 112C and the vertex of the fourth corner 112D divides the second subpixel into a first part and a second part. The first corner is a corner in the first part, and the second corner is a corner in the second part. Thus, the area where the first corner is located is the first part, and the area where the second corner is located is the second part.

[0296] For example, the ratio of the area of ​​the part where the second corner 112B is located to the area of ​​the part where the first corner 112A is located may be 0.1 to 0.95. For example, the ratio of the area of ​​the part where the second corner 112B is located to the area of ​​the part where the first corner 112A is located may be 0.3 to 0.8. For example, the ratio of the area of ​​the part where the second corner 112B is located to the area of ​​the part where the first corner 112A is located may be 0.4 to 0.7.

[0297] In general display boards, the shape and area of ​​the two portions where the two opposing corners of each subpixel are located are the same. Compared to such display boards, the display board provided by this disclosure reduces the area of ​​the portion where the second corner is located, thereby effectively improving the light transmittance of the display board when applied to a display device having an under-screen fingerprint authentication function or an under-screen camera function.

[0298] For example, as shown in FIG. 24, when the second corner 112B includes an R chamfer and the other three corners are all acute or right angles, the first straight side L1 refers to a straight line connecting the endpoint close to the third corner 112C of the curve forming the R chamfer and the vertex of the third corner 112C, the second straight side L2 refers to a straight line connecting the endpoint close to the fourth corner 112D of the curve forming the R chamfer and the vertex of the fourth corner 112D, the third straight side L3 refers to a straight line connecting the vertex of the first corner 112A and the vertex of the third corner 113, and the fourth straight side L4 refers to a straight line connecting the vertex of the first corner 112A and the vertex of the fourth corner 114.

[0299] FIG. 25 is a schematic plan view of another sub-pixel provided according to an embodiment of the present disclosure. As shown in FIGS. 24 and 25, the first corner 112A, the third corner 112C, and the fourth corner 112D may include a right angle or an acute angle, and the intersection of the two lines forming the right angle or the acute angle is the vertex of the corner. At this time, the corner can be in the range of x μm along the contour centered on the vertex, and the value of x may be 2 to 7 μm. As shown in FIG. 24, the apex angle may be a curve formed by the intersection of the extensions of the two sides of a certain apex angle at the vertex. In that case, the apex angle becomes an R chamfer. For example, in the case of the second corner 112B, the vertex of the corner may be the intersection P of the line connecting the intersection of the extension lines of the two sides forming the R chamfer and the vertex of the apex angle opposite to the R chamfer and the R chamfer. At this time, the corner can be in the range of x μm by the contour centered on the vertex P, and the value of x may be 2 to 7 μm. When the second corner is an R chamfer and the first corner is a right angle or an acute angle, the distance from the intersection of the extension lines of the two straight sides forming the first corner to the center of the sub-pixel is smaller than the distance from the intersection of the extension lines of the two straight sides forming the second corner to the center of the sub-pixel.

[0300] The "R chamfer" described above is a vertex angle formed by a curve, which may be a circular arc or an irregular curve, such as a curve cut from an ellipse or a wavy line. The embodiments of this disclosure exemplify a shape in which the curve protrudes outward relative to the center of the subpixel, but are not limited thereto, and the curve may also have a shape that is recessed inward relative to the center of the subpixel. For example, if the curve is a circular arc, the central angle of the arc may be in the range of 10° to 150°. For example, the central angle of the arc may be in the range of 60° to 120°. For example, the central angle of the arc may be 90°. For example, the length of the curve of the R chamfer included in the first corner portion 111 may be 10 to 60 μm.

[0301] In some examples, as shown in Figure 25, the vertex angle may be a line segment formed by the intersection of two sides of a vertex angle that extend to its vertex. In this case, the vertex angle becomes a planar cutout. For example, the second corner 112B includes a planar cutout, and the vertex of the corner may be the intersection point P of the planar cutout with the line connecting the intersection point of the two sides forming the planar cutout and the vertex of the vertex angle opposite the planar cutout.

[0302] Figure 26A is a schematic plan view of another subpixel provided by an embodiment of the present disclosure. Figure 26B is a schematic plan view of another subpixel provided by an embodiment of the present disclosure. As shown in Figure 26A, the first corner 112A, the second corner 112B, the third corner 112C, and the quadrilateral corner 112D all include R-chamfers, and the radius of curvature of the R-chamfer of the second corner 112B is greater than the radius of curvature of the R-chamfer of the first corner 112A. For example, if all four corners include R-chamfers, the vertex of each corner may be the intersection of the R-chamfer with the line connecting the intersection of the extensions of two sides for forming the R-chamfer and the intersection of the extensions of two sides for forming the opposite R-chamfer. In this case, each corner can be in the range of x μm along the contour centered on the vertex of the corner, and the value of x may be 2 to 7 μm.

[0303] For example, the radius of curvature of the second corner 112B may be 10% to 70% of the length of the straight side for forming the R chamfer. For example, the radius of curvature of the second corner 112B may be 20% to 50% of the length of the straight side for forming the R chamfer.

[0304] For example, the length of the line connecting the vertex of the first corner 112A and the vertex of the third corner 112C may be 40 μm. For example, the radius of curvature of the second corner 112B may be 5 to 20 μm. For example, the radius of curvature of the second corner 112B may be less than 5 μm.

[0305] For example, the radius of curvature of the R-chamfer at the second corner 111 is larger than the radius of curvature of the R-chamfers at the other three corners.

[0306] For example, as shown in Figure 26B, unlike the third type of subpixel shown in Figure 26A, the edges connecting adjacent corners are curved edges, not straight edges. The definitions of each corner and the vertices of the corners in this example are the same as in the example shown in Figure 26A.

[0307] Figure 27 is a schematic plan view of another display substrate provided by one embodiment of the present disclosure. As shown in Figure 27, the display substrate 200 includes a base substrate 210 and a pixel array structure 100 located on the base substrate 210. The pixel array structure 100 includes first subpixels 111, second subpixels 112, and third subpixels 113 configured to emit light of different colors, wherein a plurality of first subpixels 111 are arranged along a first direction to form a first type of pixel row 121 or 123, and a plurality of the second subpixels 112 and a plurality of third subpixels 113 are arranged along the first direction and alternately arranged to form a second type of pixel row 122 or 124, wherein the plurality of first type of pixel rows and a plurality of second type of pixel rows are arranged along a second direction intersecting the first direction, and the lines connecting the centers of the four first subpixels 111 surrounding the third subpixel 113 form a virtual isosceles trapezoid, and the lines connecting the centers of the four second subpixels 112 surrounding the third subpixel 113 form a virtual quadrilateral. Unlike the previously described embodiment, the shapes of the second and third subpixels in Figure 27 are different. Therefore, the schematic diagram of the pixel array structure shown in Figure 27 focuses on the shape of the subpixels, and the virtual shape formed by the lines connecting the positions and centers of the subpixels in the pixel array structure can be found in the relevant descriptions of other embodiments. In other words, the shapes of the three subpixels shown in Figure 27 can be combined with the pixel array structures shown in other embodiments.

[0308] In this pixel array structure, the lines connecting the centers of the four first subpixels surrounding the third subpixel form a virtual isosceles trapezoid, and the lines connecting the centers of the four second subpixels surrounding the third subpixel form a virtual quadrilateral. As a result, this pixel array structure can make the distribution of virtual pixels (or white dot pixels) more uniform by modulating the positions of subpixels of different colors, thereby solving display problems such as "distortion" and "granularity" caused by the human eye, and achieving a superior display effect.

[0309] For example, the first direction X and the second direction Y may be orthogonal to each other. Of course, the embodiments of this disclosure are not limited thereto, and the first direction X and the second direction Y do not have to be orthogonal to each other.

[0310] In some examples, as shown in Figure 27, the shape of the third subpixel 113 includes a pentagonal portion 113A and a hexagonal portion 113B placed opposite each other, and the distance between the vertex of the pentagonal portion 113A and the geometric center of the third subpixel 113 is greater than the distance between the vertex of the hexagonal portion 113B and the geometric center of the third subpixel 113. In other words, the shape of the third subpixel 113 is not axisymmetric. This allows the pixel array structure to reduce or avoid the occurrence of color separation by making the edges of the hexagonal portion rounder. Furthermore, by installing a third subpixel having the pentagonal portion and hexagonal portion described above, the pixel array structure can flexibly adjust the size and distance of different subpixels, thereby achieving a better display effect. Note that the above color indicators may be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the subpixel.

[0311] However, the geometric center of the subpixel may be subject to a certain error or range. For example, the geometric center of the subpixel may be within a radius of 3 μm with the geometric center of the subpixel as the center of the circle.

[0312] In some cases, as shown in Figure 27, the curvature of the curve where the vertex of the fifth corner 113A is located is greater than the curvature of the curve where the vertex of the sixth corner 113B is located. This allows the pixel array structure to have rounder edges at the second corner, thereby reducing or avoiding the occurrence of color separation.

[0313] In some cases, as shown in Figure 27, the arc length of the outer edge of the pentagon 113A is smaller than the arc length of the outer edge of the hexagon 113B.

[0314] In some examples, as shown in Figure 27, the third subpixel 113 has different orientations, for example, four orientations.

[0315] In some cases, as shown in Figure 27, the arrangement order of the pentagonal parts 113A and hexagonal parts 113B of two adjacent third subpixels 113 is different in the first direction, for example, in the first direction, the arrangement order of the pentagonal parts 113A and hexagonal parts 113B of two adjacent third subpixels 113 is different, and their arrangement directions are orthogonal to each other. In some cases, as shown in Figure 27, the arrangement order of the pentagonal parts 113A and hexagonal parts 113B of two adjacent third subpixels 113 is different in the second direction, for example, in the second direction, the arrangement order of the pentagonal parts 113A and hexagonal parts 113B of two adjacent third subpixels 113 is different, and their arrangement directions are orthogonal to each other.

[0316] In some examples, as shown in Figure 27, the lines connecting the centers of four third subpixels 113 surrounding one second subpixel 112 can form a virtual quadrilateral, and the second subpixel 112 is located within this virtual quadrilateral. The four third subpixels 113 surrounding the second subpixel 112 each have different orientations, which is advantageous in reducing color deviation and uniformizing the visual effect when displaying detailed images containing a small number of subpixels. Note that the orientation of the third subpixels mentioned above refers to the arrangement direction or order of the fifth and sixth corners.

[0317] In some examples, the shape of the second subpixel 112 is rectangular or square, as shown in Figure 27. Of course, the embodiments of this disclosure are not limited thereto, and the shape of the second subpixel 112 can be the same as the shape of the second subpixel in Figure 2.

[0318] Figure 28 is a schematic plan view of another display board provided by one embodiment of the present disclosure. As shown in Figure 28, unlike the display board shown in Figure 27, both the second and third subpixels in Figure 28 use a directional or asymmetric design.

[0319] As shown in Figure 28, the shape of the second subpixel 112 includes a first corner 112A and a second corner 112B that are placed opposite each other, and the distance between the vertex of the first corner 112A and the geometric center of the second subpixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second subpixel 112. In other words, the shape of the second subpixel 112 is not axisymmetric. The shape of the third subpixel 113 includes a fifth corner 113A and a sixth corner 113B that are placed opposite each other, and the distance between the vertex of the fifth corner 113A and the geometric center of the third subpixel 113 is greater than the distance between the vertex of the sixth corner 113B and the geometric center of the third subpixel 113. In other words, the shape of the third subpixel 113 is not axisymmetric.

[0320] In this pixel array structure, the occurrence of color separation can be reduced or avoided by making the edges of the second and hexagonal corners more rounded. Furthermore, by installing a second subpixel having the first and second corners and a third subpixel having the fifth and hexagonal corners, the size and distance of different subpixels can be flexibly adjusted, resulting in a better display effect. The above color indicators may also be parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the subpixels.

[0321] In some examples, as shown in Figure 28, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 is different in the first direction, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution of the second subpixels in the first direction, thereby improving display quality, such as improving color deviation.

[0322] In some examples, as shown in Figure 28, the arrangement order of the first corner 112A and the second corner 112B of two adjacent second subpixels 112 differs in the second direction, for example, the arrangement order is reversed. This allows the pixel arrangement structure to have a relatively uniform orientation distribution of the second subpixels in the second direction, thereby improving display quality, such as improving color deviation.

[0323] In some examples, as shown in Figure 28, the second subpixel 112 has different orientations, for example, four orientations, and the third subpixel 113 also has different orientations, for example, four orientations.

[0324] In some examples, as shown in Figure 28, the arrangement order of the pentagonal portion 113A and the hexagonal portion 113B of two adjacent third subpixels 113 is different in the first direction, and their arrangement directions are orthogonal to each other.

[0325] In some examples, as shown in Figure 28, the arrangement order of the pentagonal portion 113A and the hexagonal portion 113B of two adjacent third subpixels 113 is different in the second direction, for example, the arrangement order of the pentagonal portion 113A and the hexagonal portion 113B of two adjacent third subpixels 113 is different in the second direction, and the arrangement directions are orthogonal to each other.

[0326] In some examples, as shown in Figure 28, the lines connecting the centers of four third subpixels 113 surrounding one second subpixel 112 can form a virtual quadrilateral, and the second subpixel 112 is located within this virtual quadrilateral. The four third subpixels 113 surrounding the second subpixel 112 each have different orientations, which is advantageous in reducing color deviation and uniformizing the visual effect when displaying detailed images containing a small number of subpixels. The orientation of the third subpixels mentioned above refers to the arrangement direction or order of the fifth and sixth corners.

[0327] In some examples, as shown in Figure 28, the lines connecting the centers of four second subpixels 112 surrounding a third subpixel 113 can form a virtual quadrilateral, and the third subpixel 113 is located within this virtual quadrilateral. The four second subpixels 112 surrounding the third subpixel 113 each have different orientations, which is advantageous in reducing color deviation and uniformizing the visual effect when displaying detailed images containing a small number of subpixels. Note that the orientation of the second subpixels mentioned above refers to the arrangement direction or order of the first and second corners.
