Description

Pixel arrangement structure and display device Technical Field

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

[0002] As organic light-emitting diode (OLED) displays expand into more diverse applications and product forms, demand for electronic products using them continues to grow. These products include smartphones, TVs, computers, tablets, navigation systems, in-car dashboards, and smartwatches.

[0003] An organic light-emitting diode (OLED) display device includes a driving substrate, an organic light-emitting element and an encapsulation 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 is connected to the pixel driving circuit on the driving substrate; the encapsulation layer is located on the side of the organic light-emitting element away from the driving substrate to encapsulate the organic light-emitting element and prevent it from being degraded by water and oxygen corrosion.

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

[0091] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0092] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0093] To improve the resolution of an organic light emitting diode display device, a commonly used method currently is to use sub-pixel rendering (SPR) technology to enable different pixels to share at least one sub-pixel, thereby achieving higher resolution with relatively fewer sub-pixels.

[0094] In the field of organic light-emitting diode (OLED) displays, the human eye has different abilities to distinguish red, green, and blue sub-pixels. The brightness effects of these three sub-pixels are also different, with green sub-pixels having the greatest brightness effect, followed by red, and blue having the least. Furthermore, the lifespan of the organic light-emitting materials used in the organic light-emitting layers of different color sub-pixels varies. Therefore, in OLED displays, the area of ​​blue sub-pixels is larger than that of green sub-pixels, and vice versa.

[0095] However, in a typical pixel arrangement structure, the brightness centers of virtual pixels are usually unevenly arranged, which affects the display quality. Figure 1 is a schematic diagram of a pixel arrangement structure. As shown in Figure 1, the pixel arrangement structure includes red sub-pixels, green sub-pixels, and blue sub-pixels; the green sub-pixels are arranged along a first direction to form a plurality of green sub-pixel rows, the red sub-pixels and the blue sub-pixels are alternately arranged along the first direction to form red and blue sub-pixel rows, and the green sub-pixel rows and the red and blue sub-pixel rows are alternately arranged along a second direction perpendicular to the first direction. In this pixel arrangement structure, although the red sub-pixels, green sub-pixels, and blue sub-pixels are all evenly arranged, due to the different resolution and sensitivity of the human eye to red sub-pixels, green sub-pixels, and blue sub-pixels, the brightness centers of the virtual pixels in the human eye are not evenly arranged. For example, in a virtual pixel, the brightness center of the pixel is located between the green sub-pixel and the red sub-pixel, and is close to the green sub-pixel; the distance between the brightness center of the virtual pixel in the jth column and the brightness center of the virtual pixel in the j+1th column is greater than the distance between the brightness center of the virtual pixel in the jth column and the brightness center of the virtual pixel in the j-1th column; and the brightness center of the virtual pixel in the i-th row and the brightness center of the virtual pixel in the i+1th row are offset. Therefore, when a display device with the above-mentioned pixel arrangement structure and low resolution displays an image with vertical lines or mainly vertical lines, the human eye will produce a perceptible "sense of distortion" and "graininess". Therefore, in an organic light-emitting diode display device, the relative uniformity of the sub-pixel arrangement in physical space is not completely equivalent to the uniformity of its image display.

[0096] To this end, an embodiment of the present disclosure provides a pixel arrangement structure, which includes at least one array unit; the array unit includes a first pixel row, a second pixel row, a third pixel row, and a fourth pixel row; the first pixel row includes a plurality of first sub-pixels arranged along a first direction; the second pixel row includes a plurality of second sub-pixels and a plurality of third sub-pixels arranged and alternating along the first direction; the third pixel row includes a plurality of first sub-pixels arranged along the first direction; and the fourth pixel row includes a plurality of second sub-pixels and a plurality of third sub-pixels arranged and alternating along the first direction; 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 a line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid. Thus, the pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) more uniform by modulating the positions of sub-pixels of different colors, thereby solving display problems such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0097] The present disclosure also provides a display device including the aforementioned pixel arrangement structure. This arrangement can also achieve a more uniform distribution of virtual pixels (or white dot pixels), thereby resolving display issues such as "distortion" and "graininess" experienced by the human eye and achieving a superior display effect.

[0100] As shown in FIG2 , the pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. It should be noted that the first sub-pixels are sub-pixels that emit light of a first color, the second sub-pixels are sub-pixels that emit light of a second color, and the third sub-pixels are sub-pixels that emit light of a third color.

[0101] 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 with the first direction X, and the center line of two adjacent first sub-pixels 111 in the first pixel row 121 and the center line of two adjacent first sub-pixels 111 in the third pixel row 123 form a virtual isosceles trapezoid.

[0102] In the pixel arrangement structure provided in the embodiment of the present disclosure, as shown in Figure 3, the center line connecting two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. Therefore, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white pixel points) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0103] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0104] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0105] For example, as shown in FIG. 2 , the minimum repeating unit of the pixel arrangement structure 100 may include 16 first sub-pixels, 8 second sub-pixels, and 8 third sub-pixels.

[0106] In some examples, as shown in FIG. 2 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light.

[0107] In some examples, as shown in FIG2 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0108] For example, as shown in FIG2 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 82 to 84 degrees, for example, 83 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0109] In some examples, as shown in FIG2 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual rectangle. Thus, the third sub-pixels of this pixel arrangement structure are relatively uniform in physical spatial arrangement, and only the positions of the first sub-pixels and the second sub-pixels need to be modulated to achieve a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third sub-pixels.

[0110] 2 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual square. Thus, the third sub-pixels of the pixel arrangement structure are more uniform in physical space.

[0111] In some examples, as shown in FIG2 , a line connecting the centers of two adjacent second sub-pixels 112 in second pixel row 122 and two adjacent second sub-pixels 112 in fourth pixel row 124 forms at least one of a virtual isosceles trapezoid, a virtual square, and a virtual quadrilateral. In other words, the shape formed by the line connecting the centers of two adjacent second sub-pixels 112 in second pixel row 122 and two adjacent second sub-pixels 112 in fourth pixel row 124 can be at least one of an isosceles trapezoid, a square, and a quadrilateral. Thus, this pixel arrangement modulates the positions of the first sub-pixel and the second sub-pixel to achieve a more uniform distribution of the brightness center of the virtual pixel formed by the first, second, and third sub-pixels.

[0112] For example, as shown in FIG2 , a line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 can form three shapes, including an isosceles trapezoid, a square, and a quadrilateral; the base angle of the isosceles trapezoid is 89 degrees, the top angle is 91 degrees, and the four internal angles of the quadrilateral are 88 degrees, 92 degrees, 88 degrees, and 92 degrees, respectively, that is, the virtual quadrilateral can be a virtual parallelogram.

[0113] In some examples, as shown in Figure 2, the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B that are relatively arranged, and the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second sub-pixel 112. In other words, the shape of the second sub-pixel 112 is not an axisymmetric shape. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the edge of the second corner smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels to achieve a better display effect by providing a second sub-pixel with the above-mentioned first corner and second corner. It should be noted that the above-mentioned color indicators can be parameters such as brightness, color gamut, color temperature, wavelength, etc. of the light emitted by the sub-pixel.

[0114] It is worth noting that while only the second sub-pixel in the pixel arrangement structure 100 shown in FIG2 has the aforementioned asymmetric design or orientation, the presently disclosed embodiments include but are not limited to such asymmetric designs; both the first and third sub-pixels may employ the aforementioned asymmetric design or orientation. Furthermore, the geometric center of the aforementioned sub-pixel may be within a certain tolerance or range; for example, the geometric center of the sub-pixel may be within a range of a circle with a radius of 3 μm centered about the geometric center of the sub-pixel.

[0115] In some examples, as shown in FIG2 , the curvature of the curve at the vertex of the first corner 112A is greater than the curvature of the curve at the vertex of the second corner 112B. Thus, this pixel arrangement structure can make the edge of the second corner smoother, thereby reducing or even preventing color separation.

[0116] In some examples, as shown in FIG. 2 , the arc length of the outer edge of the first corner portion 112A is less than the arc length of the outer edge of the second corner portion 112B.

[0117] In some examples, as shown in FIG2 , in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 are arranged in different orders, for example, in opposite orders. Thus, this pixel arrangement structure can ensure a relatively uniform orientation distribution of the second sub-pixels in the first direction, thereby preventing display defects. It should be noted that the aforementioned orientation refers to the arrangement direction or order of the first corners and the second corners.

[0118] In some examples, as shown in FIG2 , the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in different orders, for example, in opposite orders. Thus, this pixel arrangement structure can ensure that the orientation distribution of the second sub-pixels in both the first and second directions is relatively uniform, thereby improving display quality.

[0119] In some examples, as shown in Figure 2, each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0120] In some examples, as shown in FIG2 , the first sub-pixel 111 has a first distance L1 and a second distance L2 from the two second sub-pixels 112 forming a virtual quadrilateral, and has a third distance L3 and a fourth distance L4 from the two third sub-pixels 113 forming a virtual quadrilateral. At least two of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are equal. Thus, this pixel arrangement structure can fully utilize process precision and improve the aperture ratio of each sub-pixel.

[0121] In some examples, as shown in FIG. 2 , the first distance L1 , the second distance L2 , the third distance L3 , and the fourth distance L4 are all equal, ie, L1 = L2 = L3 = L4 .

[0122] In some examples, as shown in FIG. 2 , the first distance L1 and the second distance L2 are equal, and the third distance L3 and the fourth distance L4 are not equal, that is, L1 = L2 and L3 ≠ L4 .

[0123] Of course, the embodiments of the present disclosure include but are not limited to the above, and the first distance L1, the second distance L2, the third distance L3 and the fourth distance L4 may also be unequal.

[0124] In some examples, the geometric center of the first sub-pixel 111 is not located at the geometric center of a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0125] In some examples, as shown in FIG2 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along a second direction Y to form a first pixel column 131. In the first pixel column 131, the angle between the center line connecting two adjacent second sub-pixels 112 and third sub-pixels 113 and the second direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) along the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0126] In some examples, as shown in FIG2 , in a first pixel column 131, the angle between the center line connecting two adjacent second sub-pixels 112 and third sub-pixels 113 and the second direction ranges from 5 to 7 degrees. Thus, this pixel arrangement structure can further uniformly distribute virtual pixels (or white dot pixels) along the first direction, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0127] In some examples, as shown in FIG2 , multiple first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. Within the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. This pixel arrangement structure can thus make the distribution of virtual pixels (or white dot pixels) along the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display quality.

[0128] In some examples, as shown in FIG2 , multiple first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. Within the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 6 to 8 degrees. This pixel arrangement structure can further uniformly distribute virtual pixels (or white dot pixels) along the first direction, thereby resolving display issues such as "distortion" and "graininess" experienced by the human eye and achieving superior display quality.

[0129] It should be noted that the shape of each sub-pixel can be defined by the opening in the pixel defining layer of the sub-pixel, and the shape of each sub-pixel is roughly the same as the shape of the opening of the corresponding pixel defining layer. In addition, each sub-pixel includes a first electrode, a pixel defining layer, a light-emitting layer and a second electrode that are stacked. When the light-emitting layer is formed in the opening in the above-mentioned pixel defining layer, the first electrode and the second electrode located on both sides of the light-emitting layer can drive the light-emitting layer in the opening of the pixel defining layer to emit light. For example, a functional layer is also provided between the light-emitting layer and the first electrode and between the light-emitting layer and the second electrode. For example, the functional layer includes any one or more layers of 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 light-emitting layer, an interface improvement layer, an anti-reflection layer, etc.

[0130] In some examples, as shown in Figure 2, the pixel arrangement structure 100 includes a first sub-pixel 111, a second sub-pixel 112 and a third sub-pixel 113, which are configured to emit light of different colors; a plurality of first sub-pixels 111 are arranged along a first direction to form a first type pixel row 121 or 123, a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are arranged along the first direction and alternately arranged to form a second type pixel row 122 or 124; a plurality of first type pixel rows and a plurality of second type pixel rows are arranged along a second direction intersecting with the first direction, and a center line connecting the four first sub-pixels 111 around the third sub-pixel 113 forms a virtual isosceles trapezoid, and a center line connecting the four second sub-pixels 112 around the third sub-pixel 113 forms a virtual quadrilateral.

[0131] In this pixel arrangement, the lines connecting the centers of the four first subpixels surrounding the third subpixel form a virtual isosceles trapezoid, while the lines connecting the centers of the four second subpixels surrounding the third subpixel form a virtual quadrilateral. This pixel arrangement modulates the positions of subpixels of different colors to achieve a more uniform distribution of virtual pixels (or white pixels), thereby resolving display issues such as "distortion" and "graininess" perceived by the human eye and achieving superior display quality.

[0132] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0133] In some examples, as shown in Figure 2, when the center of the third sub-pixel 113 is located at the intersection of the diagonals of the virtual isosceles trapezoid, the lines connecting the centers of the four second sub-pixels 112 surrounding the third sub-pixel 113 form a virtual isosceles trapezoid; when the center of the third sub-pixel 113 is not located at the intersection of the diagonals of the virtual isosceles trapezoid, the lines connecting the centers of the four second sub-pixels 112 surrounding the third sub-pixel 113 form a virtual parallelogram, a virtual rectangle, or a virtual square.

[0134] In some examples, as shown in FIG. 2 , a line connecting the centers of four third sub-pixels 113 surrounding the third sub-pixel 113 forms a virtual rectangle.

[0135] In some examples, as shown in Figure 2, the arrangement positions of multiple third sub-pixels 113 have at least the following two situations: in the first situation, the center of the third sub-pixel 113 is located at the intersection of the diagonals of the virtual rectangle formed by the center lines of the four third sub-pixels 113 surrounding the third sub-pixel 113, that is, the center of at least one third sub-pixel 113 is located at the intersection of the diagonals of the virtual rectangle formed by the center lines of the four third sub-pixels 113 surrounding the third sub-pixel 113; in the second situation, the center of the third sub-pixel 113 is not located at the intersection of the diagonals of the virtual rectangle formed by the center lines of the four third sub-pixels 113 surrounding the third sub-pixel 113, that is, the center of the third sub-pixel 113 is not located at the intersection of the diagonals of the virtual rectangle formed by the center lines of the four third sub-pixels 113 surrounding the third sub-pixel 113.

[0136] In some examples, as shown in FIG. 2 , a plurality of third sub-pixels 113 adjacent to each other in the second direction are arranged at third and fourth intervals along the second direction, and a size of the third interval in the second direction is smaller than a size of the fourth interval in the second direction.

[0137] FIG4 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in FIG4 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0138] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0139] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0140] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0141] For example, as shown in FIG. 4 , the minimum repeating unit of the pixel arrangement structure 100 may include 16 first sub-pixels, 8 second sub-pixels, and 8 third sub-pixels.

[0142] In some examples, as shown in FIG. 4 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light.

[0143] In some examples, as shown in FIG4 , in a first pixel row 121, a plurality of first sub-pixels 111 are arranged along a first direction at intervals S1 and S2, with the first interval S1 being smaller than the second interval S2, and the first interval S1 and the second interval S2 being arranged alternately. In other words, the distances between adjacent first sub-pixels 111 in the first direction are unequal, with two intervals, the first interval S1 and the second interval S2. In this case, to fully utilize process precision (e.g., the manufacturing precision of a fine metal mask) and improve the pixel aperture ratio, two opposing corners of two first sub-pixels 111 on either side of the first interval may be chamfered to form first chamfered portions, thereby increasing the width of the first interval and reducing the difference between the first interval and the second interval.

[0144] For example, as shown in FIG. 4 , the curvature of the outer edge of the first chamfered portion is smaller than the curvature of the outer edge of the non-chamfered corner of the first sub-pixel 111 .

[0145] In some examples, as shown in FIG. 4 , the first sub-pixel 111 is in the shape of an elongated strip, thus having an extension direction; the angle between the extension direction of the first sub-pixel 111 and the first direction or the second direction is in the range of 30-60 degrees.

[0146] In some examples, as shown in FIG. 4 , the extension directions of two adjacent first sub-pixels 111 in the first direction are symmetrically arranged with respect to the second direction; that is, the two adjacent first pixels in the first direction are symmetrically arranged with respect to the second direction.

[0147] In some examples, as shown in FIG4 , due to the chamfered corners of the first sub-pixels 111, the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 84 to 86 degrees, for example, 85 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first, second, and third sub-pixels more uniform.

[0148] In some examples, as shown in Figure 4, the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B that are relatively arranged, and the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second sub-pixel 112. In other words, the shape of the second sub-pixel 112 is not an axisymmetric shape. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the edge of the second corner smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels to achieve a better display effect by providing a second sub-pixel with the above-mentioned first corner and second corner. It should be noted that the above-mentioned color indicators can be parameters such as brightness, color gamut, color temperature, wavelength, etc. of the light emitted by the sub-pixel.

[0149] In some examples, as shown in Figure 4, the curvature of the curve at the vertex of the first corner 112A is greater than the curvature of the curve at the vertex of the second corner 112B. Thus, this pixel arrangement structure can make the edge of the second corner smoother, thereby reducing or even avoiding the occurrence of color separation.

[0150] In some examples, as shown in FIG4 , in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 are arranged in different orders, for example, in opposite orders. Thus, this pixel arrangement structure can ensure a relatively uniform orientation distribution of the second sub-pixels in the first direction, thereby preventing display defects. It should be noted that the aforementioned orientation refers to the arrangement direction or order of the first corners and the second corners.

[0151] In some examples, as shown in FIG4 , the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in different orders, for example, in opposite orders. Thus, this pixel arrangement structure can ensure that the orientation distribution of the second sub-pixels in both the first and second directions is relatively uniform, thereby improving display quality.

[0152] FIG5 is a planar schematic diagram of another display substrate provided by an embodiment of the present disclosure. As shown in FIG5 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0153] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0154] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0155] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0156] In some examples, as shown in FIG5 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light.

[0157] In some examples, as shown in FIG5 , in a first pixel row 121, a plurality of first sub-pixels 111 are arranged along a first direction at intervals S1 and S2, with the first interval S1 being smaller than the second interval S2, and the first intervals S1 and S2 being arranged alternately. In other words, the distances between adjacent first sub-pixels 111 in the first direction are unequal, with two intervals, the first interval S1 and the second interval S2. In this case, to fully utilize process precision (e.g., the precision of manufacturing a fine metal mask) and to increase the pixel aperture ratio, two opposing corners of two first sub-pixels 111 on either side of the first interval may be chamfered to form first chamfered portions.

[0158] For example, as shown in FIG. 5 , the curvature of the outer edge of the first chamfered portion is smaller than the curvature of the outer edge of the non-chamfered corner of the first sub-pixel 111 .

[0159] In some examples, as shown in FIG5 , the two opposing corners of the two first sub-pixels 111 on either side of the second interval S2 can be chamfered to form second chamfered portions. Thus, the pixel arrangement structure can further utilize process precision (e.g., the precision of manufacturing a fine metal mask) and improve the pixel aperture ratio. Furthermore, the shape of the first sub-pixel is more symmetrical.

[0160] For example, as shown in FIG. 5 , the curvature of the outer edge of the second chamfered portion is smaller than the curvature of the outer edge of the non-chamfered corner of the first sub-pixel 111 .

[0161] FIG6 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure; FIG7 is a schematic diagram of the brightness center of a virtual pixel of a display substrate provided in an embodiment of the present disclosure. As shown in FIG6 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0162] In the pixel arrangement structure provided in the embodiment of the present disclosure, as shown in Figure 7, the center line connecting two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. Therefore, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white pixel points) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0163] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0164] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0165] In some examples, as shown in FIG6 , the minimum repeating unit of the pixel arrangement structure 100 includes four first sub-pixels, two second sub-pixels, and three third sub-pixels.

[0166] In some examples, as shown in FIG6 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0167] In some examples, as shown in FIG. 6 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along the second direction Y to form a first pixel column 131 .

[0168] In some examples, as shown in FIG6 , the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B disposed opposite each other, wherein the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second sub-pixel 112. In the first pixel column 131, the first corner 112A and the second corner 112B of the second sub-pixel 112 are disposed opposite each other in the second direction. In other words, in this pixel arrangement structure, the first corner 112A and the second corner 112B of the second sub-pixel 112 are disposed in the second direction, i.e., the second sub-pixel 112 has an orientation in the second direction, thereby reducing the difficulty of manufacturing the corresponding mask. Of course, embodiments of the present disclosure include but are not limited to this, and the first corner 112A and the second corner 112B of the second sub-pixel 112 may also be disposed opposite each other in the first direction.

[0169] For example, as shown in FIG6 , the first corner portion 112A of the second sub-pixel 112 is located above the second corner portion 112B, that is, the second sub-pixel 112 is oriented upward.

[0170] In some examples, as shown in Figure 6, the curvature of the curve at the vertex of the first corner 112A is greater than the curvature of the curve at the vertex of the second corner 112B. Thus, this pixel arrangement structure can make the edge of the second corner smoother, thereby reducing or even avoiding the occurrence of color separation.

[0171] In some examples, as shown in FIG6 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0172] For example, as shown in FIG6 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 82 to 84 degrees, for example, 83 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0173] In some examples, as shown in FIG6 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual square. Thus, the third sub-pixels of this pixel arrangement structure are relatively uniform in physical spatial arrangement, and only the positions of the first sub-pixels and the second sub-pixels need to be modulated to achieve a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third sub-pixels.

[0174] In some examples, as shown in FIG6 , a line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 forms a virtual square. Thus, this pixel arrangement modulates only the position of the first sub-pixel, so that the distribution of the brightness center of the virtual pixel formed by the first, second, and third sub-pixels is more uniform.

[0175] In some examples, as shown in FIG6 , in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 are arranged in the same order. The first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in the same order. Thus, this pixel arrangement structure can simplify the manufacturing of masks for the second sub-pixels.

[0176] In some examples, as shown in FIG6 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0177] In some examples, as shown in FIG6 , a line connecting the centers of two adjacent second sub-pixels 112 and third sub-pixels 113 in the second direction is parallel to the second direction.

[0178] In some examples, as shown in FIG6 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 1 to 10 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0179] In some examples, as shown in FIG6 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 5 to 9 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0180] In some examples, as shown in FIG6 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction is in the range of 7-9 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0181] In some examples, as shown in FIG6 , multiple first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. Within the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. This pixel arrangement structure can thus make the distribution of virtual pixels (or white dot pixels) along the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display quality.

[0182] In some examples, as shown in FIG6 , multiple 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 angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 6 to 8 degrees. Thus, this pixel arrangement structure can further uniformly distribute virtual pixels (or white dot pixels) along the first direction, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display quality.

[0183] In some examples, as shown in FIG6 , the first sub-pixel 111 has a first distance L1 and a second distance L2 from the two second sub-pixels 112 forming a virtual quadrilateral, and has a third distance L3 and a fourth distance L4 from the two third sub-pixels 113 forming a virtual quadrilateral. At least two of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are equal. Thus, this pixel arrangement structure can fully utilize process precision and improve the aperture ratio of each sub-pixel.

[0184] In some examples, as shown in FIG6 , the first distance L1 , the second distance L2 , the third distance L3 , and the fourth distance L4 are all equal, ie, L1 = L2 = L3 = L4 .

[0185] In some examples, as shown in FIG6 , the first distance L1 and the second distance L2 are equal, and the third distance L3 and the fourth distance L4 are not equal, that is, L1 = L2 and L3 ≠ L4.

[0186] Of course, the embodiments of the present disclosure include but are not limited to the above, and the first distance L1, the second distance L2, the third distance L3 and the fourth distance L4 may also be unequal.

[0187] In some examples, the geometric center of the first sub-pixel 111 is not located at the geometric center of a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0188] FIG8 is a schematic plan view of another display substrate provided in an embodiment of the present disclosure. As shown in FIG8 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0189] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0190] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0191] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0192] In some examples, as shown in FIG8 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0193] In some examples, as shown in FIG. 8 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along the second direction Y to form a first pixel column 131 .

[0194] In some examples, as shown in FIG8 , the shape of second sub-pixel 112 includes a first corner 112A and a second corner 112B that are oppositely disposed. The distance between the vertex of first corner 112A and the geometric center of second sub-pixel 112 is greater than the distance between the vertex of second corner 112B and the geometric center of second sub-pixel 112. In first pixel column 131, first corner 112A and second corner 112B of second sub-pixel 112 are oppositely disposed in the second direction. In other words, in this pixel arrangement, first corner 112A and second corner 112B of second sub-pixel 112 are disposed in the second direction, i.e., second sub-pixel 112 has an orientation in the second direction, thereby reducing the difficulty of manufacturing the corresponding mask.

[0195] For example, as shown in FIG8 , the first corner portion 112A of the second sub-pixel 112 is located below the second corner portion 112B, that is, the second sub-pixel 112 is oriented downward.

[0196] In some examples, as shown in FIG8 , in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 are arranged in the same order. The first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in the same order. Thus, this pixel arrangement structure can simplify the manufacturing of masks for the second sub-pixels.

[0197] In some examples, as shown in FIG8 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0198] In some examples, as shown in FIG. 8 , a line connecting the centers of two adjacent second sub-pixels 112 and third sub-pixels 113 in the second direction is parallel to the second direction.

[0199] In some examples, as shown in FIG8 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 1 to 10 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0200] In some examples, as shown in FIG8 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction is in the range of 5-7 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0201] In some examples, as shown in FIG8 , multiple first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. Within the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. This pixel arrangement structure can thus make the distribution of virtual pixels (or white dot pixels) along the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display quality.

[0202] In some examples, as shown in FIG8 , multiple first sub-pixels 111 are arranged along a second direction Y to form a second pixel column 132. Within the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 6 to 8 degrees. This pixel arrangement structure can further uniformly distribute virtual pixels (or white dot pixels) along the first direction, thereby resolving display issues such as "distortion" and "graininess" experienced by the human eye and achieving superior display quality.

[0203] FIG9 is a schematic plan view of another display substrate provided in an embodiment of the present disclosure. As shown in FIG9 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0204] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0205] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0206] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0207] In some examples, as shown in FIG9 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0208] In some examples, as shown in FIG. 9 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along the second direction Y to form a first pixel column 131 .

[0209] In some examples, as shown in FIG9 , the shape of second sub-pixel 112 includes a first corner 112A and a second corner 112B that are oppositely disposed. The distance between the vertex of first corner 112A and the geometric center of second sub-pixel 112 is greater than the distance between the vertex of second corner 112B and the geometric center of second sub-pixel 112. In first pixel column 131, first corner 112A and second corner 112B of second sub-pixel 112 are oppositely disposed in a first direction. In other words, in this pixel arrangement, first corner 112A and second corner 112B of second sub-pixel 112 are disposed in the first direction, i.e., second sub-pixel 112 has an orientation in the first direction, thereby reducing the difficulty of manufacturing the corresponding mask.

[0210] For example, as shown in FIG9 , the first corner 112A of the second sub-pixel 112 is located to the right of the second corner 112B, that is, the second sub-pixel 112 is oriented to the right.

[0211] In some examples, as shown in FIG9 , in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 are arranged in the same order. The first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in the same order. Thus, this pixel arrangement structure can simplify the manufacturing of masks for the second sub-pixels.

[0212] In some examples, as shown in FIG9 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0213] In some examples, as shown in FIG9 , the angle between the second direction and the center line between two adjacent second sub-pixels 112 and third sub-pixels 113 in the second direction is in the range of 1-15 degrees, for example, 1 degree.

[0214] In some examples, as shown in FIG9 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0215] In some examples, as shown in FIG9 , in the second pixel row 122 or the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction is in the range of 6-8 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the second direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0216] In some examples, as shown in FIG9 , multiple 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 angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0217] In some examples, as shown in FIG9 , multiple 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 angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 6 to 8 degrees. Thus, this pixel arrangement structure can further uniformly distribute virtual pixels (or white dot pixels) along the first direction, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display quality.

[0218] FIG10 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure; FIG11 is a schematic diagram of the distribution of brightness centers of virtual pixels of another display substrate provided in an embodiment of the present disclosure. As shown in FIG10 , the display substrate 200 includes a pixel arrangement structure 100. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0219] In the pixel arrangement structure provided in the embodiment of the present disclosure, as shown in Figure 11, the center line connecting two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid, rather than a rectangle or square. Therefore, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white pixel points) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0220] On the other hand, as shown in Figure 11, the brightness centers of the virtual pixels in the pixel arrangement structure 100 have three different distributions: the first distribution for the brightness centers of the virtual pixels in odd rows, the second distribution for the brightness centers of the virtual pixels in odd columns of even rows, and the third distribution for the brightness centers of the virtual pixels in even columns of even rows. Thus, the pixel arrangement structure utilizes multiple virtual pixel brightness distributions to better modulate the brightness, resulting in higher white point brightness uniformity across the entire screen. Furthermore, when the pixel borrowing algorithm uses two or more second and third sub-pixels to borrow from the first sub-pixel, multiple virtual pixel brightness distributions can also better achieve uniform white point brightness across the entire screen.

[0221] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0222] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0223] In some examples, as shown in FIG10 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0224] In some examples, as shown in FIG10 , the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B that are arranged opposite each other, and the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second sub-pixel 112. In the second pixel row 122 and the fourth pixel row 124, the first corners 112A and the second corners 112B of two adjacent second sub-pixels 112 are arranged in the same order, that is, the orientations of the two adjacent second sub-pixels 112 are the same. It should be noted that because the distance between the vertex of the first corner and the geometric center of the second sub-pixel is greater than the distance between the vertex of the second corner and the geometric center of the second sub-pixel, the second sub-pixels have an orientation in the arrangement direction of the first and second corners.

[0225] In some examples, as shown in FIG10 , the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixels 112 in the second pixel row 122 is perpendicular to the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixels 112 in the fourth pixel row 124. Thus, the second sub-pixels in this pixel arrangement structure have two perpendicular orientations.

[0226] For example, as shown in FIG10 , the orientations of the two adjacent second sub-pixels 112 in the first direction are both leftward, that is, the first corner 112A is located to the left of the second corner 112B; the orientations of the two adjacent second sub-pixels 112 in the second direction are both upward, that is, the second corner 112A is located above the second corner 112B.

[0227] In some examples, as shown in FIG10 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0228] For example, as shown in FIG10 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 82 to 84 degrees, for example, 83 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0229] In some examples, as shown in FIG10 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual square. Thus, the third sub-pixels of this pixel arrangement are relatively uniform in physical spatial arrangement, requiring only the positions of the first sub-pixels and the second sub-pixels to be modulated to achieve a more uniform distribution of the brightness centers of the virtual pixels formed by the first, second, and third sub-pixels.

[0230] In some examples, as shown in FIG10 , a line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 forms a virtual isosceles trapezoid. Thus, this pixel arrangement modulates the positions of the first sub-pixel and the second sub-pixel to make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0231] In some examples, as shown in FIG10 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0232] In some examples, as shown in Figure 10, the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixels 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 1-15 degrees, and the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixels 113 in the second direction and the second direction is in the range of 1-15 degrees.

[0233] In some examples, as shown in FIG10 , the angle between the center line of the adjacent second sub-pixels 112 and third sub-pixels 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 6-8 degrees.

[0234] In some examples, as shown in FIG. 10 , an angle between a line connecting the centers of the second sub-pixel 112 and the third sub-pixel 113 adjacent to each other in the second direction and the second direction may be 1 degree.

[0235] In some examples, as shown in FIG10 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along the second direction Y to form a first pixel column 131; and a plurality of first sub-pixels 111 are arranged along the second direction Y to form a second pixel column 132. In the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0236] In some examples, as shown in FIG10 , in the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 6 to 8 degrees, for example, 7 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0237] In some examples, as shown in FIG10 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0238] In some examples, as shown in FIG10 , the first sub-pixel 111 has a first distance L1 and a second distance L2 from the two second sub-pixels 112 forming a virtual quadrilateral, and has a third distance L3 and a fourth distance L4 from the two third sub-pixels 113 forming a virtual quadrilateral. At least two of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are equal. Thus, this pixel arrangement structure can fully utilize process precision and improve the aperture ratio of each sub-pixel.

[0239] In some examples, as shown in FIG10 , the first distance L1 , the second distance L2 , the third distance L3 , and the fourth distance L4 are all equal, ie, L1 = L2 = L3 = L4 .

[0240] In some examples, as shown in FIG. 10 , the first distance L1 and the second distance L2 are equal, and the third distance L3 and the fourth distance L4 are not equal, that is, L1 = L2 and L3 ≠ L4 .

[0241] Of course, the embodiments of the present disclosure include but are not limited to the above, and the first distance L1, the second distance L2, the third distance L3 and the fourth distance L4 may also be unequal.

[0242] In some examples, the geometric center of the first sub-pixel 111 is not located at the geometric center of a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0243] FIG12 is a planar schematic diagram of another display substrate provided by an embodiment of the present disclosure. As shown in FIG12 , the display substrate 200 includes a pixel arrangement structure 100. Unlike the display substrate shown in FIG10 , the orientation of two adjacent second sub-pixels 112 in the first direction is both leftward, i.e., the first corner 112A is located to the left of the second corner 112B; and the orientation of two adjacent second sub-pixels 112 in the second direction is both downward, i.e., the second corner 112A is located above the second corner 112B. In other words, when the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixels 112 in the second pixel row 122 is perpendicular to the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixels 112 in the fourth pixel row 124, the orientation of the second sub-pixels 112 in the second pixel row 122 can be leftward or rightward, while the orientation of the second sub-pixels 112 in the fourth pixel row 124 can be upward or downward.

[0244] FIG13 is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As shown in FIG13 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0245] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0246] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0247] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second and third sub-pixels can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0249] In some examples, as shown in FIG13 , the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B arranged opposite to each other, and the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 112B and the geometric center of the second sub-pixel 112; 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 sub-pixels 112 is the same; the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixel 112 in the second pixel row 122 is opposite to the arrangement direction of the first corner 112A and the second corner 112B of the second sub-pixel 112 in the fourth pixel row 124.

[0250] In some examples, as shown in FIG. 13 , first corner 112A of second subpixel 112 in second pixel row 122 is below second corner 112B, and first corner 112A of second subpixel 112 in fourth pixel row 124 is above second corner 112B.

[0251] In some examples, as shown in FIG13 , the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 1-15 degrees, and the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second direction and the second direction is in the range of 1-15 degrees.

As shown in FIG14 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210.

[0254] In some examples, as shown in FIG14 , the angle between the center line of the adjacent second sub-pixels 112 and third sub-pixels 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 7-8 degrees, for example, 7 degrees.

[0255] In some examples, as shown in FIG14 , the angle between the second direction and a line connecting the centers of the second sub-pixel 112 and the third sub-pixel 113 adjacent to each other in the second direction is in the range of 1-3 degrees, for example, 1 degree.

As shown in FIG15 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. Unlike the display substrate shown in FIG13 , in the pixel arrangement structure shown in FIG15 , the first corner 112A of the second sub-pixel 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 sub-pixel 112 in the fourth pixel row 124 is located to the right of the second corner 112B.

[0257] FIG16 is a planar schematic diagram of another display substrate provided by an embodiment of the present disclosure. As shown in FIG16 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement 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 a 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 and alternately disposed along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternately disposed along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0258] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0259] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0260] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0261] In some examples, as shown in FIG16 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0262] In some examples, as shown in FIG16 , the shape of the second sub-pixel 112 includes a first corner 112A and a second corner 112B oppositely disposed, wherein the distance between the vertex of the first corner 112A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the first corner 112B and the geometric center of the second sub-pixel 112; in the second pixel row 122 and the fourth pixel row 124, the first corners 112A and the second corners 112B of two adjacent second sub-pixels 112 are arranged in the same order; the arrangement direction of the first corners 112A and the second corners 112B of the second sub-pixels 112 in the second pixel row 122 is perpendicular to the arrangement direction of the first corners 112A and the second corners 112B of the second sub-pixels 112 in the fourth pixel row 124; and the arrangement order of the first corners 112A and the second corners 112B of two adjacent second sub-pixels 112 in the second direction is different, for example, opposite. In other words, the second sub-pixel 112 has three orientations, two of which are parallel and one is perpendicular to the other two orientations.

[0263] 16 , a line connecting the centers of the two third sub-pixels 113 of the second pixel row 122 and the two third sub-pixels 113 of the fourth pixel row 124 may form a virtual square. A line connecting the centers of the two second sub-pixels 112 of the second pixel row 122 and the two second sub-pixels 112 of the fourth pixel row 124 may form a virtual isosceles trapezoid.

[0264] In some examples, as shown in FIG16 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0265] In some examples, as shown in FIG16 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0266] In some examples, as shown in FIG16 , the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 1-15 degrees, and the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second direction and the second direction is in the range of 1-15 degrees.

[0267] In some examples, as shown in FIG16 , the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 1-3 degrees; the angle between the center line of the adjacent second sub-pixels 112 and the third sub-pixel 113 in the second pixel row 122 and the fourth pixel row 124 and the first direction is in the range of 5-7 degrees.

[0268] In some examples, as shown in FIG16 , in a pixel column where the first corner 112A of the second sub-pixel 112 is located above the second corner 112 , an angle between a line connecting the centers of the second sub-pixel 112 and the third sub-pixel 113 adjacent in the second direction and the second direction may be 1 degree.

[0269] In some examples, as shown in FIG16 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0270] In some examples, as shown in FIG16 , the first sub-pixel 111 has a first distance L1 and a second distance L2 from the two second sub-pixels 112 forming a virtual quadrilateral, and has a third distance L3 and a fourth distance L4 from the two third sub-pixels 113 forming a virtual quadrilateral. At least two of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are equal. Thus, this pixel arrangement structure can fully utilize process precision and improve the aperture ratio of each sub-pixel.

[0271] In some examples, as shown in FIG. 16 , the first distance L1 , the second distance L2 , the third distance L3 , and the fourth distance L4 are all equal, ie, L1 = L2 = L3 = L4 .

[0272] In some examples, as shown in FIG. 16 , the first distance L1 and the second distance L2 are equal, and the third distance L3 and the fourth distance L4 are not equal, that is, L1 = L2 and L3 ≠ L4 .

[0273] Of course, the embodiments of the present disclosure include but are not limited to the above, and the first distance L1, the second distance L2, the third distance L3 and the fourth distance L4 may also be unequal.

[0274] In some examples, the geometric center of the first sub-pixel 111 is not located at the geometric center of a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0275] FIG17 is a planar schematic diagram of another display substrate provided by an embodiment of the present disclosure. As shown in FIG17 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. Unlike the display substrate shown in FIG16 , in the pixel arrangement structure shown in FIG17 , in the second pixel row 122 and the fourth pixel row 124, the arrangement order of the first corners 112A and the second corners 112B of two adjacent second sub-pixels 112 is different, for example, the arrangement order is opposite; the arrangement direction of the first corners 112A and the second corners 112B of the second sub-pixels 112 in the second pixel row 122 is perpendicular to the arrangement direction of the first corners 112A and the second corners 112B of the second sub-pixels 112 in the fourth pixel row 124, and the arrangement order of the first corners 112A and the second corners 112B of two adjacent second sub-pixels 112 in the second direction is the same.

[0276] FIG18 is a schematic diagram of three shapes of a second sub-pixel provided in an embodiment of the present disclosure; FIG19 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure; and FIG20 is a planar schematic diagram of another display substrate provided in an embodiment of the present disclosure. As shown in FIG19-20, the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0277] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0278] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0279] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0280] In some examples, as shown in Figures 19-20, the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light. Of course, embodiments of the present disclosure include but are not limited to this, and the colors of light emitted by the second sub-pixel and the third sub-pixel can be interchangeable, that is, the second sub-pixel is configured to emit red light and the third sub-pixel is configured to emit blue light.

[0281] In some examples, as shown in FIG18 , the shape of the second sub-pixel 112 includes at least one of a first shape 1121, a second shape 1122, and a third shape 1123; the first shape 1121 includes a first corner 1121A and a second corner 1121B that are oppositely disposed, and the distance between the vertex of the first corner 1121A and the geometric center of the second sub-pixel 112 is greater than the distance between the vertex of the second corner 1121B and the geometric center of the second sub-pixel 112; the second shape 1122 includes a third corner 1122A and a flattened portion 1122B that are oppositely disposed, and the edge of the flattened portion 1122B away from the third corner 1122A is a straight line. ;The third shape 1123 includes a fourth corner 1123A and a fifth corner 1123B arranged opposite to each other in the first direction and a sixth corner 1123C and a seventh corner 1123D arranged opposite to 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, 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 sixth corner 1123C and the geometric center of the second sub-pixel 112, and the fifth corner 1123B and the seventh corner 1123D are adjacent to each other.

[0282] In some examples, as shown in FIG19 , in the pixel arrangement structure 100 , the second sub-pixels 112 have a second shape. In the second pixel row 122 and the fourth pixel row 124 , adjacent second sub-pixels 112 have the same orientation, and adjacent second sub-pixels 112 in the second direction have the same orientation.

[0283] In some examples, as shown in FIG. 20 , in the pixel arrangement structure, the shape of the second sub-pixel 112 includes a second shape and a first shape.

[0284] 20 , the shape of the second sub-pixels 112 in the second pixel row 122 is different from the shape of the second sub-pixels 112 in the fourth pixel row 124. For example, the shape of the second sub-pixels 112 in the second pixel row 122 is a first shape, and the shape of the second sub-pixels 112 in the fourth pixel row 124 is a second shape.

[0285] It is worth noting that when the embodiment of the present disclosure discloses that the shape of the second sub-pixel 112 includes at least one of the above-mentioned first shape, second shape and third shape, the pixel arrangement structure can adopt any one of the three second sub-pixels having the above-mentioned three shapes or a combination of at least two of them, which will not be repeated here.

[0286] FIG21 is a schematic plan view of another display substrate provided in an embodiment of the present disclosure. As shown in FIG21 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0287] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0288] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0289] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0290] In some examples, as shown in FIG. 21 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light.

[0291] In some examples, as shown in FIG21 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0292] For example, as shown in FIG21 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 86 to 88 degrees, for example, 87 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0293] In some examples, as shown in FIG. 21 , a line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 112 in the fourth pixel row 124 forms a virtual square.

[0294] In some examples, as shown in FIG. 21 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual quadrilateral.

[0295] For example, as shown in Figure 21, the four internal angles of the virtual quadrilateral formed by the center line connecting two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 are 83 degrees, 90 degrees, 97 degrees and 90 degrees respectively.

[0296] In some examples, as shown in Figure 21, the shapes of the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 are all rectangular or rounded rectangles. It should be noted that the rounded rectangles are rectangles with rounded corners.

[0297] In some examples, as shown in FIG21 , each first sub-pixel 111 is located within a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. In other words, each first sub-pixel 111 is surrounded by two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113. Thus, this pixel arrangement structure can better achieve pixel borrowing and achieve higher display quality.

[0298] In some examples, as shown in FIG21 , the first sub-pixel 111 has a first distance L1 and a second distance L2 from the two second sub-pixels 112 forming a virtual quadrilateral, and has a third distance L3 and a fourth distance L4 from the two third sub-pixels 113 forming a virtual quadrilateral. At least two of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 are equal. Thus, this pixel arrangement structure can fully utilize process precision and improve the aperture ratio of each sub-pixel.

[0299] In some examples, as shown in FIG. 21 , the first distance L1 , the second distance L2 , the third distance L3 , and the fourth distance L4 are all equal, ie, L1 = L2 = L3 = L4 .

[0300] In some examples, as shown in FIG. 21 , the first distance L1 and the second distance L2 are equal, and the third distance L3 and the fourth distance L4 are not equal, that is, L1 = L2, L3≠L4.

[0301] Of course, the embodiments of the present disclosure include but are not limited to the above, and the first distance L1, the second distance L2, the third distance L3 and the fourth distance L4 may also be unequal.

[0302] In some examples, the geometric center of the first sub-pixel 111 is not located at the geometric center of a virtual quadrilateral formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0303] In some examples, as shown in FIG21 , a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are alternately arranged along the second direction to form a first pixel column; a plurality of first sub-pixels 111 are arranged along the second direction Y to form a second pixel column 132. In the second pixel column 132, the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0304] In some examples, as shown in FIG21 , the angle between the center line connecting two adjacent first sub-pixels 111 and the second direction ranges from 2 to 4 degrees, for example, 3 degrees. Thus, this pixel arrangement structure can further make the distribution of virtual pixels (or white dot pixels) in the first direction more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0305] In some examples, as shown in FIG. 21 , in the first pixel row 121 and the third pixel row 123 , a line connecting the centers of two adjacent first sub-pixels 111 is parallel to the first direction.

[0306] In some examples, as shown in FIG21 , in the second pixel row 122 and the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 1 to 15 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0307] In some examples, as shown in FIG21 , in the second pixel row 122 and the fourth pixel row 124, the angle between the center line connecting the adjacent second sub-pixels 112 and third sub-pixels 113 and the first direction ranges from 6 to 8 degrees, for example, 7 degrees. Thus, this pixel arrangement structure can make the distribution of virtual pixels (or white dot pixels) more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a better display effect.

[0308] FIG22 is a schematic plan view of another display substrate provided by an embodiment of the present disclosure. As shown in FIG22 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement 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 a 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 and alternating along the first direction X; the third pixel row 123 includes a plurality of first sub-pixels 111 arranged along the first direction X; and the fourth pixel row 124 includes a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 arranged and alternating along the first direction X. 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 a line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 forms a virtual isosceles trapezoid.

[0309] In the pixel arrangement structure provided in the embodiments of the present disclosure, the line connecting the centers of two adjacent first sub-pixels in the first pixel row and two adjacent first sub-pixels in the third pixel row forms a virtual isosceles trapezoid, rather than a rectangle or square. As a result, this pixel arrangement structure can achieve a more uniform distribution of virtual pixels (or white dot pixels) by modulating the positions of sub-pixels of different colors, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0310] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0311] For example, the array unit described above may be a minimum repeating unit of the pixel arrangement structure, and the array unit may be arranged repeatedly in the first direction and the second direction to cover the entire display substrate. Of course, the embodiments of the present disclosure include but are not limited to this, and the array unit described above may also be larger than the minimum repeating unit, or smaller than the minimum repeating unit.

[0312] In some examples, as shown in FIG. 22 , the first sub-pixel 111 is configured to emit green light, the second sub-pixel 112 is configured to emit blue light, and the third sub-pixel 113 is configured to emit red light.

[0313] In some examples, as shown in FIG22 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 75 degrees to 90 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform, thereby better solving display problems such as "distortion" and "graininess" produced by the human eye.

[0314] For example, as shown in FIG22 , the base angle of the virtual isosceles trapezoid formed by the line connecting the centers of two adjacent first sub-pixels 111 in the first pixel row 121 and two adjacent first sub-pixels 111 in the third pixel row 123 ranges from 86 to 88 degrees, for example, 87 degrees. Thus, this pixel arrangement structure can make the distribution of the brightness center of the virtual pixel formed by the first sub-pixel, the second sub-pixel, and the third sub-pixel more uniform.

[0315] In some examples, as shown in FIG. 22 , a line connecting the centers of two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 forms a virtual quadrilateral.

[0316] For example, as shown in Figure 22, the four internal angles of the virtual quadrilateral formed by the center line connecting two adjacent third sub-pixels 113 in the second pixel row 122 and two adjacent third sub-pixels 113 in the fourth pixel row 124 are 83 degrees, 90 degrees, 97 degrees and 90 degrees respectively.

[0317] In some examples, as shown in FIG. 22 , a line connecting the centers of two adjacent second sub-pixels 112 in the second pixel row 122 and two adjacent second sub-pixels 122 in the fourth pixel row 124 forms at least one of a virtual isosceles trapezoid, a virtual square, and a virtual parallelogram.

[0318] In some examples, as shown in FIG. 22 , each first sub-pixel 111 is located within a virtual trapezoid formed by a line connecting the centers of two adjacent second sub-pixels 112 and two adjacent third sub-pixels 113 .

[0319] At least one embodiment of the present disclosure further provides a display device. FIG23 is a schematic diagram of a display device provided by one embodiment of the present disclosure. As shown in FIG23 , the display device 500 includes the aforementioned pixel arrangement structure 100. Thus, the display device can also make the distribution of virtual pixels (or white dot pixels) more uniform, thereby resolving display issues such as "distortion" and "graininess" produced by the human eye and achieving a superior display effect.

[0320] For example, the display device can be an electronic product with display function, such as a smart phone, a television, a computer, a tablet computer, a navigation system, a car central control screen, and a smart watch.

[0321] At least one embodiment of the present disclosure also provides a planar schematic diagram of a sub-pixel in another display substrate. Figure 24 is a planar schematic diagram of another sub-pixel provided by an embodiment of the present disclosure. As shown in Figure 24, the second sub-pixel 112 includes a first corner 112A and a second corner 112A; the distance from the intersection of the extension lines of the two straight sides L1 and L2 constituting the first corner 112A to the center O of the sub-pixel 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 sub-pixel. It should be noted that although Figure 24 describes and illustrates the shape of the sub-pixel using the second sub-pixel as an example, the embodiment of the present disclosure does not limit the second sub-pixel to adopt the above-mentioned shape. Both the first sub-pixel and the third sub-pixel can adopt the above-mentioned shape.

[0322] In the display substrate provided in the embodiment of the present disclosure, the actual brightness center of each virtual pixel unit is adjusted by making the distance from the intersection of the extension lines of the two straight sides constituting the first corner to the center of the sub-pixel different from the distance from the intersection of the two straight sides constituting the second corner or their extension lines to the center of the sub-pixel, so as to make the actual brightness center distribution of each virtual pixel in the pixel arrangement structure or the display substrate more uniform.

[0323] In some examples, as shown in FIG24 , the second sub-pixel 112 further includes a third corner 112C and a fourth corner 112D that are relatively disposed, and a line connecting the vertices of the third corner 112C and the fourth corner 112D divides the second sub-pixel into two parts, the two parts have 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.

[0324] 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 sub-pixel into a first part and a second part. The first corner is the corner in the first part, and the second corner is the corner in the second part. The part where the first corner is located refers to the first part, and the part where the second corner is located refers to the second part.

[0325] For example, the ratio of the area of ​​the portion where the second corner portion 112B is located to the area of ​​the portion where the first corner portion 112A is located may be 0.1 to 0.95. For example, the ratio of the area of ​​the portion where the second corner portion 112B is located to the area of ​​the portion where the first corner portion 112A is located may be 0.3 to 0.8. For example, the ratio of the area of ​​the portion where the second corner portion 112B is located to the area of ​​the portion where the first corner portion 112A is located may be 0.4 to 0.7.

[0326] It should be noted that in a general display substrate, the shapes and areas of the two parts where the two corners opposite to each other in each sub-pixel are located are the same. Compared with such a display substrate, the display substrate provided by the present disclosure can effectively improve the transmittance of the display substrate when the display substrate is applied to a display device with an under-screen fingerprint function or an under-screen camera function by reducing the area of ​​the part where the second corner is located.

[0327] For example, as shown in Figure 24, when the second corner 112B includes a rounded chamfer and the other three corners are acute angles or right angles, the first straight side L1 refers to a straight line connecting the end point of the curve constituting the rounded chamfer close to the third corner 112C and the vertex of the third corner 112C, the second straight side L2 refers to a straight line connecting the end point of the curve constituting the rounded chamfer close to the fourth corner 112D 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.

[0328] FIG25 is a schematic plan view of another sub-pixel provided in an embodiment of the present disclosure. As shown in FIG24 and FIG25 , the first corner 112A, the third corner 112C, and the fourth corner 112D may include right angles or acute angles; the intersection of the two lines forming the right angle or acute angle is the vertex of the corner. In this case, the corner may be a range of x microns along the contour centered on the vertex, where the value of x can be 2 to 7 microns. As shown in FIG24 , the vertex may also be a curved line formed by the intersection of two sides of a vertex extending toward its vertex, so that the vertex becomes a rounded chamfer. For example, for the second corner 112B, the vertex of the corner may be the intersection of the extended lines of the two sides used to form the rounded chamfer and the intersection point P of the line connecting the vertex of the vertex opposite the rounded chamfer and the rounded chamfer. In this case, the corner may be a range of x microns along the contour centered on the vertex P, where the value of x can be 2 to 7 microns. When the second corner is a rounded 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 constituting 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 constituting the second corner to the center of the sub-pixel.

[0329] The above-mentioned "rounded chamfer" is the vertex angle formed by a curve, which can be an arc or an irregular curve, such as a curve intercepted from an ellipse, a wavy line, etc. The embodiment of the present disclosure schematically shows that the curve has a shape that is convex outward relative to the center of the sub-pixel, but is not limited to this. The curve can also have a shape that is concave inward relative to the center of the sub-pixel. For example, when the curve is an arc, the range of the central angle of the arc can be 10° to 150°. For example, the range of the central angle of the arc can be 60° to 120°. For example, the range of the central angle of the arc can be 90°. For example, the length of the rounded chamfer included in the first corner 111 can be 10 to 60 microns.

[0330] In some examples, as shown in Figure 25, the above-mentioned vertex angle can also be a line segment formed by the part where two sides of a vertex angle extend toward its vertex and intersect to make the vertex angle a chamfer. For example, the second corner 112B includes a chamfer, and the vertex of the corner can be the intersection point P of the line connecting the intersection of the two sides used to form the above-mentioned chamfer and the vertex of the vertex angle opposite to the chamfer and the chamfer.

[0331] FIG26A is a planar schematic diagram of another sub-pixel provided in an embodiment of the present disclosure; FIG26B is a planar schematic diagram of another sub-pixel provided in an embodiment of the present disclosure. As shown in FIG26A , the first corner 112A, the second corner 112B, the third corner 112C, and the fourth corner 112D all include rounded chamfers, and the radius of curvature of the rounded chamfer of the second corner 112B is greater than the radius of curvature of the rounded chamfer of the first corner 112A. For example, when all four corners include rounded chamfers, the vertex of each corner can be the intersection of the extension lines of the two sides used to form the rounded chamfer and the intersection of the extension lines of the two sides used to form the rounded chamfer opposite to the rounded chamfer, and the intersection of the rounded chamfer. In this case, each corner can be a range of x microns along the contour centered on the vertex of the corner, and the value of x can be 2 to 7 microns.

[0332] For example, the curvature radius of the second corner portion 112B may be 10% to 70% of the length of the rounded straight side. For example, the curvature radius of the second corner portion 112B may be 20% to 50% of the length of the rounded straight side.

[0333] For example, the length of the line connecting the apex of the first corner portion 112A and the apex of the third corner portion 112C may be 40 micrometers. For example, the curvature radius of the second corner portion 112B may be 5 to 20 micrometers. For example, the curvature radius of the second corner portion 112B may be less than 5 micrometers.

[0334] For example, the curvature radius of the fillet of the second corner 111 is greater than the curvature radius of the fillets of the other three corners.

[0335] For example, as shown in FIG26B , the difference from the third type sub-pixel shown in FIG26A is that the edges connecting adjacent corners are curved edges rather than straight edges. The definition of each corner and the definition of the vertex in the corner in this example are the same as those in the example shown in FIG26A .

[0336] FIG27 is a schematic plan view of another display substrate provided in an embodiment of the present disclosure. As shown in FIG27 , the display substrate 200 includes a base substrate 210 and a pixel arrangement structure 100 located on the base substrate 210. The pixel arrangement structure 100 includes a first sub-pixel 111, a second sub-pixel 112, and a third sub-pixel 113, configured to emit light of different colors. A plurality of first sub-pixels 111 are arranged along a first direction to form a first-type pixel row 121 or 123, and a plurality of second sub-pixels 112 and a plurality of third sub-pixels 113 are arranged and alternately disposed along the first direction to form a second-type pixel row 122 or 124. The plurality of first-type pixel rows and the plurality of second-type pixel rows are arranged along a second direction intersecting the first direction. A line connecting the centers of the four first sub-pixels 111 around the third sub-pixel 113 forms a virtual isosceles trapezoid, and a line connecting the centers of the four second sub-pixels 112 around the third sub-pixel 113 forms a virtual quadrilateral. It should be noted that, unlike the aforementioned embodiments, the second and third sub-pixels in FIG. 27 have different shapes. Therefore, the schematic diagram of the pixel arrangement structure shown in FIG. 27 focuses more on the sub-pixel shapes, while the positions of the sub-pixels in this pixel arrangement structure and the virtual shape formed by the center line can be found in the relevant descriptions of other embodiments. In other words, the three sub-pixel shapes shown in FIG. 27 can be incorporated into the pixel arrangement structures shown in other embodiments.

[0337] In this pixel arrangement, the lines connecting the centers of the four first subpixels surrounding the third subpixel form a virtual isosceles trapezoid, while the lines connecting the centers of the four second subpixels surrounding the third subpixel form a virtual quadrilateral. This pixel arrangement modulates the positions of subpixels of different colors to achieve a more uniform distribution of virtual pixels (or white pixels), thereby resolving display issues such as "distortion" and "graininess" perceived by the human eye and achieving superior display quality.

[0338] For example, the first direction X and the second direction Y may be perpendicular to each other. Of course, the embodiments of the present disclosure include but are not limited to this, and the first direction X and the second direction Y may not be perpendicular to each other.

[0339] In some examples, as shown in Figure 27, the shape of the third sub-pixel 113 includes a fifth corner 113A and a sixth corner 113B that are relatively arranged, and the distance between the vertex of the fifth corner 113A and the geometric center of the third sub-pixel 113 is greater than the distance between the vertex of the sixth corner 113B and the geometric center of the third sub-pixel 113. In other words, the shape of the third sub-pixel 113 is not an axisymmetric shape. Therefore, the pixel arrangement structure can reduce or even avoid the occurrence of color separation by making the edge of the sixth corner smoother. In addition, the pixel arrangement structure can also flexibly adjust the size and distance of different sub-pixels to achieve a better display effect by providing a third sub-pixel with the above-mentioned fifth and sixth corners. It should be noted that the above-mentioned color indicators can be parameters such as brightness, color gamut, color temperature, wavelength, etc. of the light emitted by the sub-pixels.

[0340] It should be noted that the geometric center of the sub-pixel may be within a certain error or range; for example, the geometric center of the sub-pixel may be within a range with a radius of 3 μm, centered at the geometric center of the sub-pixel.

[0341] In some examples, as shown in Figure 27, the curvature of the curve at the vertex of the fifth corner 113A is greater than the curvature of the curve at the vertex of the sixth corner 113B. Thus, this pixel arrangement structure can make the edge of the second corner smoother, thereby reducing or even preventing the occurrence of color separation.

[0342] In some examples, as shown in FIG. 27 , the arc length of the outer edge of the fifth corner portion 113A is less than the arc length of the outer edge of the sixth corner portion 113B.

[0343] In some examples, as shown in FIG. 27 , the third sub-pixel 113 has different orientations, for example, four orientations.

[0344] In some examples, as shown in FIG27 , the fifth corners 113A and the sixth corners 113B of two third sub-pixels 113 adjacent in the first direction are arranged in a different order; for example, the fifth corners 113A and the sixth corners 113B of two third sub-pixels 113 adjacent in the first direction are arranged in a different order, and the arrangement directions are perpendicular to each other. In some examples, as shown in FIG27 , the fifth corners 113A and the sixth corners 113B of two third sub-pixels 113 adjacent in the second direction are arranged in a different order; for example, the fifth corners 113A and the sixth corners 113B of two third sub-pixels 113 adjacent in the second direction are arranged in a different order, and the arrangement directions are perpendicular to each other.

[0345] In some examples, as shown in FIG27 , a line connecting the centers of four third sub-pixels 113 surrounding a second sub-pixel 112 can form a virtual quadrilateral, with the second sub-pixel 112 located within the virtual quadrilateral.

The distance between the vertex of first corner 112A and the geometric center of second subpixel 112 is greater than the distance between the vertex of second corner 112B and the geometric center of second subpixel 112. In other words, the shape of second subpixel 112 is not axisymmetric. The shape of third subpixel 113 includes a fifth corner 113A and a sixth corner 113B that are disposed opposite each other.

Furthermore, by providing a second sub-pixel having the first and second corners and a third sub-pixel having the fifth and sixth corners, this pixel arrangement allows for flexible adjustment of the size and distance between different sub-pixels to achieve a better display effect. It should be noted that the aforementioned color indicators can include parameters such as the brightness, color gamut, color temperature, and wavelength of the light emitted by the sub-pixels.

[0350] In some examples, as shown in FIG28 , the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the first direction are arranged in different orders, for example, in opposite orders. Thus, this pixel arrangement structure can ensure that the orientation distribution of the second sub-pixels in the first direction is relatively uniform, thereby improving display quality, for example, by reducing color shift.

[0351] In some examples, as shown in FIG28 , the first corners 112A and second corners 112B of two adjacent second sub-pixels 112 in the second direction are arranged in different orders, for example, in opposite orders.

[0355] In some examples, as shown in FIG28 , a line connecting the centers of four third sub-pixels 113 surrounding a second sub-pixel 112 can form a virtual quadrilateral, with the second sub-pixel 112 located within the virtual quadrilateral. The four third sub-pixels 113 surrounding the second sub-pixel 112 have different orientations, which can help reduce color cast and provide a more uniform visual effect when displaying detailed images with a small number of sub-pixels. It should be noted that the third sub-pixel orientation described above refers to the arrangement direction or order of the fifth and sixth corners.
