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

[0002] With the continuous development of display technology, people have higher and higher requirements for the resolution of display devices. Due to the advantages of high display quality, the application range of high-resolution display devices is also getting wider and wider. Generally, the resolution of a display device can be improved by reducing the size of pixels and reducing the spacing between pixels. However, the reduction of the size of pixels and the spacing between pixels also places higher and higher requirements on the precision of the manufacturing process, which will lead to an increase in the difficulty of the manufacturing process of the display device and the increase in the manufacturing cost.

[0003] On the other hand, sub-pixel rendering (SPR) technology can take advantage of the difference in the human eye's resolution of sub-pixels of different colors, change the conventional red, green, and blue sub-pixels that simply define a pixel, and share certain sub-pixels of color that are not sensitive to resolution between different pixels. By using a relatively small number of sub-pixels, it can simulate the same pixel resolution performance, thereby reducing the difficulty and cost of the production process. Summary of the invention

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0033] During the study, the inventors of the present application noticed that: in order to manufacture a display device with high resolution, it is necessary to reduce the size of pixels and the spacing between pixels; however, the reduction of the size of pixels and the spacing between pixels also places higher and higher requirements on the precision of the manufacturing process, which will lead to an increase in the difficulty of the manufacturing process and the manufacturing cost of the display device. For example, when manufacturing an active matrix organic light emitting diode (AMOLED) display device with high resolution, due to the limitation of the process precision of the fine metal mask (FMM) technology, the manufacturing process of the active matrix organic light emitting diode (AMOLED) display device with high resolution (for example, greater than 300 pixel density (PPI)) is difficult and the manufacturing cost is high.

[0034] The disclosed embodiment provides a pixel arrangement structure, a display substrate, a display device and a mask. The pixel arrangement structure includes a plurality of first color sub-pixel blocks, a plurality of second color sub-pixel blocks and a plurality of third color sub-pixel blocks distributed in a plurality of minimum repeating regions, the minimum repeating region is rectangular and includes a first virtual rectangle, a first virtual rectangle includes a first color sub-pixel block, a second color sub-pixel block and a third color sub-pixel block, the first virtual rectangle includes a first side extending along a first direction and a second side extending along a second direction, the second color sub-pixel block and the third color sub-pixel block are distributed on both sides of the perpendicular midline of the first side, the distances between the second color sub-pixel block and the third color sub-pixel block and the first side are both less than the distance between the first color sub-pixel block and the first side, the center of the first color sub-pixel block is located on the perpendicular midline of the first side and the distance from the first side is 1 / 2-3 / 4 of the length of the second side. Thus, the pixel arrangement structure can improve the distribution uniformity of the sensitive color sub-pixels by adjusting the spacing of the sensitive color sub-pixels, thereby improving the visual resolution of the pixel arrangement structure, and also improving the display quality of the pixel arrangement structure.

[0035] The pixel arrangement structure, display substrate, display device and mask provided by the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0036] At least one embodiment of the present disclosure provides a pixel arrangement structure. Figure 1 The schematic diagram of a pixel arrangement structure provided according to an embodiment of the present disclosure includes a plurality of first color sub-pixel blocks 111 , a plurality of second color sub-pixel blocks 112 , and a plurality of third color sub-pixel blocks 113 distributed in a plurality of minimum repeating units 100 . Figure 1 A minimal repeat region 100 is shown, such as Figure 1 As shown, each minimum repeating region 100 includes a first virtual rectangle 110, and each first virtual rectangle 110 includes a first color sub-pixel block 111, a second color sub-pixel block 112, and a third color sub-pixel block 113. The first virtual rectangle 110 includes a first side 1101 extending along a first direction and a second side 1102 extending along a second direction, the second color sub-pixel block 112 and the third color sub-pixel block 113 are distributed on both sides of the perpendicular midline of the first side 1101, the distances between the second color sub-pixel block 112 and the third color sub-pixel block 113 and the first side 1101 are both smaller than the distance between the first color sub-pixel block 111 and the first side 1101, the center of the first color sub-pixel block 111 is located on the perpendicular midline of the first side 1101, and the distance between the first color sub-pixel block 111 and the first side 1101 is 1 / 2-3 / 4 of the length of the second side 1102. For example, as Figure 1As shown, the length of the second side 1102 is L, and the distance between the center of the first color sub-pixel block 111 and the first side 1101 is (1 / 2-3 / 4) L. It should be noted that the above-mentioned first virtual rectangle is to better describe the position of the first color sub-pixel block, and is not an actual structure. In addition, the range of the virtual rectangle of the above-mentioned first virtual rectangle may be larger than the light-emitting area of ​​the first color sub-pixel block, the second color sub-pixel block and the third color sub-pixel block in the first virtual rectangle. The above-mentioned "center" refers to the geometric center of the shape of the sub-pixel block (for example: the first color sub-pixel block, the second color sub-pixel block or the third color sub-pixel block); the distance between the above-mentioned second color sub-pixel block and the third color sub-pixel block and the first side refers to the distance between the center of the second color sub-pixel block and the center of the third color sub-pixel block and the first side.

[0037] In the pixel arrangement structure provided in this embodiment, since the second color sub-pixel block and the third color sub-pixel block are distributed on both sides of the perpendicular midline of the first side, and the center of the first color sub-pixel block is located on the perpendicular midline of the first side and the distance from the first side is 1 / 2-3 / 4 of the length of the second side; therefore, the center distance between two adjacent first color sub-pixel blocks is greater than 1 / 2 of the length of the second side, thereby avoiding the situation where the two adjacent first color sub-pixel blocks are difficult to distinguish due to the close distance between the adjacent first color sub-pixel blocks and are visually combined into one by the human eye, thereby avoiding the resulting graininess. Therefore, the pixel arrangement structure can improve the distribution uniformity of the first color sub-pixel blocks, thereby improving the visual resolution and the display quality.

[0038] It should be noted that when designing the pixel arrangement structure, the sub-pixel block is generally designed to be a regular shape, such as a hexagon, a pentagon, a trapezoid or other shapes. When designing, the center of the sub-pixel block can be the geometric center of the above-mentioned regular shape. However, in the actual manufacturing process, the shape of the sub-pixel block formed generally has a certain deviation from the regular shape of the above-mentioned design. For example, each corner of the above-mentioned regular shape may become a rounded corner, so the shape of the sub-pixel block can be a rounded corner figure. In addition, the shape of the sub-pixel block actually manufactured may also have other changes from the designed shape. For example, the shape of the sub-pixel block designed as a hexagon may become an approximate ellipse in actual manufacturing. Therefore, the center of the sub-pixel block may not be the strict geometric center of the irregular shape of the sub-pixel block formed by manufacturing. In the embodiment of the present disclosure, the center of the sub-pixel block may have a certain offset from the geometric center of the shape of the sub-pixel block. The center of a sub-pixel block refers to any point in the area enclosed by a specific point on a radial line segment from the geometric center of the sub-pixel block to each edge point of the sub-pixel block, and the specific point on the radial line segment is at a distance from the geometric center of 1 / 3 of the length of the radial line segment. The definition of the center of a sub-pixel block is applicable to the center of a sub-pixel block of a regular shape, and also to the center of a sub-pixel block of an irregular shape. For example, in some examples, the above-mentioned minimum repeating area can be repeatedly arranged in translation to form a complete pixel arrangement structure. It should be noted that the minimum repeating area does not include sub-units that can be repeatedly arranged in translation.

[0039] For example, in some examples, the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel 113 can be used as a sub-pixel for display, and the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel block 113 in the first virtual rectangle 110 can form a pixel unit for color display. Of course, the embodiments of the present disclosure include but are not limited to this, and the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel 113 can be respectively combined with adjacent sub-pixels of the same color into one sub-pixel for display.

[0040] For example, in some examples, the first color sub-pixel block is a sensitive color sub-pixel. Due to the different sensitivity of the human eye to color, when adjacent sensitive color sub-pixels are close to each other, it is more likely that two adjacent sensitive color sub-pixels are difficult to distinguish due to the close distance between adjacent sensitive color sub-pixels, and are visually combined into one by the human eye. Therefore, the pixel arrangement structure can improve the distribution uniformity of the sensitive color sub-pixels, thereby improving the visual resolution and the display quality. It should be noted that when the pixel arrangement structure adopts the red, green and blue (RGB) mode, the above-mentioned sensitive color is green.

[0041] For example, in some examples, the first color sub-pixel block is a green sub-pixel, the second color sub-pixel block is a red sub-pixel, and the third color sub-pixel block is a blue sub-pixel, or the first color sub-pixel block is a green sub-pixel, the second color sub-pixel block is a blue sub-pixel, and the third color sub-pixel block is a red sub-pixel. Of course, the embodiments of the present disclosure include but are not limited to this.

[0042] For example, in some examples, the distance between the edge of the first color sub-pixel block 111 close to the first side 1101 and the first side 1101 is 1 / 3-5 / 12 of the length of the second side 1102. Therefore, the distance between the two closest edges of two adjacent first color sub-pixel blocks is greater than 1 / 6 of the length of the second side.

[0043] For example, in some examples, the distance between the center of the first color sub-pixel block and the first side is 9 / 16-11 / 16 of the length of the second side. Thus, the distribution uniformity of the first color sub-pixel blocks can be further improved, thereby further improving the visual resolution and the display quality.

[0044] For example, in some examples, the distance between the center of the first color sub-pixel block and the first side is 5 / 8 of the length of the second side. Thus, the distribution uniformity of the first color sub-pixel blocks can be further improved, thereby further improving the visual resolution and the display quality.

[0045] For example, in some examples, the virtual rectangle may be a square, that is, the lengths of the first side and the second side are equal.

[0046] For example, in some examples, such as Figure 1As shown, each minimum repeating region 100 further includes a second virtual rectangle 120, a third virtual rectangle 130 and a fourth virtual rectangle 140. The first virtual rectangle 110, the second virtual rectangle 120, the third virtual rectangle 130 and the fourth virtual rectangle 140 form a 2*2 matrix in a co-edge manner to constitute the minimum repeating region 100. The second virtual rectangle 120 and the first virtual rectangle share a first side 1101 and are mirror-symmetric with the first virtual rectangle 110 about the first side 1101; the first virtual rectangle 110 is translated along its diagonal by a distance of the length of a diagonal line and overlaps with the third virtual rectangle 130; the third virtual rectangle 130 includes a third side 1303 extending along the first direction, and the fourth virtual rectangle 140 shares a third side 1303 with the third virtual rectangle 130 and is mirror-symmetric with the third virtual rectangle 130 about the third side 1303. It should be noted that the first virtual rectangle, the second virtual rectangle, the third virtual rectangle and the fourth virtual rectangle are closely arranged to form a minimum repeating region in the shape of a rectangle. It should be noted that the above repetition means that the three sub-pixel blocks in the third virtual rectangle are the same in shape and position as the three sub-pixel blocks in the first virtual rectangle that are translated along the diagonal of the first virtual rectangle by the length of a diagonal line. The repetition here only refers to the repetition of pixel blocks, and other structures may be different or the same. In addition, the above repetition means that the approximate position, shape, and size are similar. In some cases, for the needs of wiring or opening holes, the shapes may be slightly different, such as opening holes at different positions.

[0047] It should be noted that, for the overlap described in the present disclosure, it means that at least 70% of the area of ​​the corresponding sub-pixels or other components can overlap; for the mirror symmetry described in the present disclosure, it means that after the mirror operation, at least 70% of the area of ​​the corresponding sub-pixels can overlap. In the pixel arrangement structure provided in the present embodiment, since the second virtual rectangle is mirror-symmetric with the first virtual rectangle, the structure of the third virtual rectangle is the same as the structure of the first virtual rectangle translated along the diagonal of the first virtual rectangle, and the fourth virtual rectangle is mirror-symmetric with the third virtual rectangle; the distance between the center of the first color sub-pixel block in the third virtual rectangle and the third side is 1 / 2-3 / 4 of the length of the second side, and the distance between the center of the first color sub-pixel block in the fourth virtual rectangle and the third side is 1 / 2-3 / 4 of the length of the second side, therefore, the distance between the center of the first color sub-pixel block in the third virtual rectangle and the center of the first color sub-pixel block in the fourth virtual rectangle is greater than 1 / 2 of the length of the second side, thereby avoiding the situation that the two adjacent first color sub-pixel blocks are difficult to distinguish due to the close distance between the adjacent first color sub-pixel blocks, and are visually combined into one by the human eye, thereby avoiding the resulting graininess. Therefore, the pixel arrangement structure can improve the distribution uniformity of the first color sub-pixel blocks, thereby increasing the visual resolution and improving the display quality.

[0048] In addition, if Figure 1 As shown, since the distance between the center of the first color sub-pixel block in the first virtual rectangle and the first side is 1 / 2-3 / 4 of the length of the second side, and the distance between the center of the first color sub-pixel block in the fourth virtual rectangle and the third side is 1 / 2-3 / 4 of the length of the second side, the slopes of the first color sub-pixel block in the first virtual rectangle and the first color sub-pixel block in the fourth virtual rectangle are relatively low; therefore, when the pixel units belonging to the same row (for example, the first virtual rectangle and the fourth virtual rectangle) display a straight line together, since the slopes of the first color sub-pixel block in the first virtual rectangle and the first color sub-pixel block in the fourth virtual rectangle are relatively low, the fluctuation amplitude of the first color sub-pixel block in the first virtual rectangle and the first color sub-pixel block in the fourth virtual rectangle is relatively small, thereby avoiding the situation that the two straight lines generated by the interlocking with the straight lines displayed in the adjacent rows due to the large fluctuation amplitude are difficult to distinguish and are visually combined into one by the human eye. Therefore, the pixel arrangement structure can improve the visual resolution.

[0049] In addition, the pixel arrangement structure can improve the uniformity of sub-pixel distribution in the pixel arrangement structure and avoid the formation of color lines by making the second virtual rectangle mirror-symmetrical with the first virtual rectangle, the structure of the third virtual rectangle being the same as the structure of the first virtual rectangle translated along the diagonal of the first virtual rectangle, and the fourth virtual rectangle being mirror-symmetrical with the third virtual rectangle. In addition, in the minimum repeating area 100, since there is no color mixing problem for sub-pixels of the same color, and the second color sub-pixel block 112 of the first virtual rectangle 110 is close to the second color sub-pixel block 112 of the second virtual rectangle 120, when the pixel arrangement structure is applied to an organic light-emitting display device, the light-emitting layer of the second color sub-pixel block 112 of the first virtual rectangle 110 and the light-emitting layer of the second color sub-pixel block 112 of the second virtual rectangle 120 can be formed through the same mask opening; similarly, when the pixel arrangement structure is applied to an organic light-emitting display device, the third color sub-pixel block 113 of the first virtual rectangle 110 and the third color sub-pixel block 113 of the second virtual rectangle 120 are close to each other, and the light-emitting layer of the third color sub-pixel block 113 of the first virtual rectangle 110 and the light-emitting layer of the third color sub-pixel block 113 of the second virtual rectangle 120 can also be formed through the same mask opening.

[0050] For example, in some examples, the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel block 113 in the second virtual rectangle 120 may form a pixel unit for color display; the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel block 113 in the third virtual rectangle 120 may form a pixel unit for color display; the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel block 113 in the fourth virtual rectangle 120 may form a pixel unit for color display.

[0051] In the pixel arrangement structure provided in this embodiment, since the second color sub-pixel block and the third color sub-pixel block are distributed on both sides of the perpendicular midline of the first side, and the center of the first color sub-pixel block is located on the perpendicular midline of the first side and the distance from the first side is 1 / 2-3 / 4 of the length of the second side; therefore, the center distance between two adjacent first color sub-pixel blocks is greater than 1 / 2 of the length of the second side, thereby avoiding the situation where the two adjacent first color sub-pixel blocks are difficult to distinguish due to the close distance between the adjacent first color sub-pixel blocks and are visually combined into one by the human eye, thereby avoiding the resulting graininess. Therefore, the pixel arrangement structure can improve the distribution uniformity of the first color sub-pixel blocks, thereby improving the visual resolution and the display quality.

[0052] For example, in some examples, such as Figure 1 As shown, in the first virtual rectangle 110, the second color sub-pixel block 112 and the third color sub-pixel block 113 are respectively close to the two ends of the first side 1101. It should be noted that, according to the relationship between the second virtual rectangle, the third virtual rectangle and the fourth virtual rectangle and the first virtual rectangle, the positional relationship between the second color sub-pixel block and the third color sub-pixel block of the second virtual rectangle, the third virtual rectangle and the fourth virtual rectangle also changes accordingly. For example, Figure 1 As shown, in the fourth virtual rectangle 140, the distance between the center of the first color sub-pixel block 111 and the upper edge of the fourth virtual rectangle 140 (equivalent to the first side 1101 in the first virtual rectangle 110) is 1 / 2-3 / 4 of the length of the second side.

[0053] For example, in some examples, such as Figure 1 As shown, within the first virtual rectangle 110, the edges of the second color sub-pixel block 112 and the third color sub-pixel block 113 away from the center of the first virtual rectangle 110 are located on the first side, so that the space within the first virtual rectangle can be used to the maximum extent. It should be noted that, according to the relationship between the second virtual rectangle, the third virtual rectangle, and the fourth virtual rectangle and the first virtual rectangle, the positional relationship between the second color sub-pixel blocks and the third color sub-pixel blocks of the second virtual rectangle, the third virtual rectangle, and the fourth virtual rectangle also changes accordingly.

[0054] For example, in some examples, such as Figure 1 As shown, the shortest distances between the first color sub-pixel block 111, the second color sub-pixel block 112, and the third color sub-pixel block 113 are equal. In other words, the shortest distance between the first color sub-pixel block 111 and the second color sub-pixel block 112, the shortest distance between the first color sub-pixel block 111 and the third color sub-pixel block 113, and the shortest distance between the second color sub-pixel block 112 and the third color sub-pixel block 113 are equal, so that the process accuracy can be maximized.

[0055] For example, in some examples, such as Figure 1 As shown, the shape of the second color sub-pixel block 112 is the same as the shape of the third color sub-pixel block 113, and the shape of the second color sub-pixel block 112 and the shape of the third color sub-pixel block 113 are symmetrical about the diagonal line between the right angle formed by the first connecting line 121 and the second connecting line 122 of the shape of the first color sub-pixel block 111. Thus, the symmetry and uniformity of the pixel arrangement structure can be further improved, thereby further improving the display quality.

[0056] For example, in some examples, such as Figure 1 As shown, the shape of the first color sub-pixel block 111 is a right-angled symmetrical pentagon, which is symmetrical about the perpendicular bisector of the first side 1101, and the base of the right-angled symmetrical pentagon is parallel to the first side 1101 or located on the first side 1101, and is farther away from the first side 1101 than the vertex of the right-angled symmetrical pentagon in the direction perpendicular to the first side 1101. Figure 1 As shown, the two oblique sides of the first color sub-pixel block 111 can be arranged relative to the second color sub-pixel block 112 and the third color sub-pixel block 113, respectively, so that when the process precision is constant, that is, when the distances between the first color sub-pixel block 111 and the second color sub-pixel block 112 and the third color sub-pixel block 113 are constant, the area of ​​the first color sub-pixel block 111 is increased. Thus, the pixel arrangement structure can improve the utilization rate of the space within the first virtual rectangle. It should be noted that the above relative arrangement means that the two oblique sides of the first color sub-pixel block 111 face the second color sub-pixel block 112 and the third color sub-pixel block 113, respectively.

[0057] For example, in some examples, such as Figure 1As shown, the second color sub-pixel block 112 and the third color sub-pixel block 113 are both symmetrical pentagons with right-angle base angles, which are symmetrical about the perpendicular bisector of the first side, and the base of the symmetrical pentagon is parallel to the first side 1101 or located on the first side 1101, and is closer to the first side 1101 than the vertex of the symmetrical pentagon in the direction perpendicular to the first side 1101. Figure 1 As shown, the hypotenuses of the second color sub-pixel block 112 and the third color sub-pixel block 113 close to the first color sub-pixel block 111 can be respectively arranged opposite to the first color sub-pixel block 111, so that when the process precision is constant, that is, when the distances between the first color sub-pixel block 111 and the second color sub-pixel block 112 and the third color sub-pixel block 113 are respectively constant, the areas of the second color sub-pixel block 112 and the third color sub-pixel block 113 are increased. Thus, the pixel arrangement structure can improve the utilization rate of the space within the first virtual rectangle.

[0058] It should be noted that, although the shape of each sub-pixel block in the drawings includes a strict angle formed by two line segments, in some embodiments, the shape of each sub-pixel block may be a rounded shape. That is, on the basis of the above-mentioned various shapes, the corners of each sub-pixel block are rounded. For example, in the case where the light-emitting layer is evaporated through a mask, the portion of the light-emitting layer located at the corner may naturally form a rounded shape.

[0059] Figure 2 FIG. 1 is a schematic diagram of another pixel arrangement structure provided according to an embodiment of the present disclosure. Figure 2 As shown, the second color sub-pixel block 112 and the third color sub-pixel block 113 are both in the shape of a right-angled trapezoid, the bottom side of the right-angled trapezoid is perpendicular to the first side 1101, and the distance between the right-angled side of the right-angled trapezoid and the first side 1101 is smaller than the distance between the hypotenuse of the right-angled trapezoid and the first side 1101. Figure 2As shown, the hypotenuse of the second color sub-pixel block 112 and the third color sub-pixel block 113 can be arranged opposite to the first color sub-pixel block 111, so that when the process precision is constant, that is, when the distance between the first color sub-pixel block 111 and the second color sub-pixel block 112 and the third color sub-pixel block 113 is constant, the area of ​​the second color sub-pixel block 112 and the third color sub-pixel block 113 is increased. Thus, the pixel arrangement structure can improve the utilization rate of the space in the first virtual rectangle. Moreover, since the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled trapezoids, relative to the situation that the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled bottom angle symmetrical pentagons, the acute angle portion 190 of the second color sub-pixel block 112 and the third color sub-pixel block 113 can further increase the area of ​​the second color sub-pixel block 112 and the third color sub-pixel block 113, thereby further improving the utilization rate of the space in the first virtual rectangle.

[0060] For example, in some examples, such as Figure 2 As shown, the shape of the first color sub-pixel block 111 is a right-angled symmetrical pentagon, which is symmetrical about the perpendicular bisector of the first side, and the base of the right-angled symmetrical pentagon is parallel to the first side 1101, and is farther away from the first side relative to the vertex of the right-angled symmetrical pentagon in the direction perpendicular to the first side, the right-angled symmetrical pentagon includes a third hypotenuse 193 and a fourth hypotenuse 194 passing through the vertex of the right-angled symmetrical pentagon, the third hypotenuse 193 and the fourth hypotenuse 194 have the same length, the third hypotenuse 193 of the first color sub-pixel block 111 is parallel to the hypotenuse of the second color sub-pixel block 112 and the spacing is the fifth distance, the fourth hypotenuse 194 of the first color sub-pixel block 111 is parallel to the hypotenuse of the third color sub-pixel block and the spacing is the sixth distance.

[0061] For example, in some examples, such as Figure 2As shown, in the first virtual rectangle 110 and the second virtual rectangle 120, the third color sub-pixel block 113 is closer to the center of the minimum repeat region 100 than the second color sub-pixel block 112, and in the third virtual rectangle 130 and the fourth virtual rectangle 140, the second color sub-pixel block 112 is closer to the center of the minimum repeat region 100 than the third color sub-pixel block 113, and the third color sub-pixel block 113 in the first virtual rectangle 110 is adjacent to the second color sub-pixel block 120 in the fourth virtual rectangle 140. The third color sub-pixel block 113 in the second virtual rectangle 120 is adjacent to the second color sub-pixel block 112 in the third virtual rectangle 130, the acute angle 190 of the third color sub-pixel block 113 in the first virtual rectangle 110 is the seventh distance away from the acute angle 190 of the second color sub-pixel block 112 in the fourth virtual rectangle 140, and the acute angle 190 of the third color sub-pixel block 113 in the second virtual rectangle 120 is the eighth distance away from the acute angle 190 of the second color sub-pixel block 112 in the third virtual rectangle 130.

[0062] For example, in some examples, such as Figure 2 As shown, the fifth distance, the sixth distance, the seventh distance and the eighth distance are all equal.

[0063] Figure 3 FIG. 1 is a schematic diagram of another pixel arrangement structure provided according to an embodiment of the present disclosure. Figure 3As shown, the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled pentagons, the base of the right-angled pentagon is parallel to the first side 1101 or is located on the first side 1101, and is closer to the first side 1101 relative to the vertex of the right-angled pentagon in a direction perpendicular to the first side 1101, the right-angled pentagon includes a first hypotenuse 191 and a second hypotenuse 192 passing through the vertex, the first hypotenuse 191 is arranged opposite to the first color sub-pixel block 111, and the length of the first hypotenuse 191 is greater than the length of the second hypotenuse 192. For example, the first oblique side 191 of the second color sub-pixel block 112 is arranged opposite to the first color sub-pixel block 111, and the first oblique side 191 of the third color sub-pixel block 113 is arranged opposite to the first color sub-pixel block 111. Therefore, under the condition of certain process accuracy, that is, under the condition that the distances between the first color sub-pixel block 111 and the second color sub-pixel block 112 and the third color sub-pixel block 113 are respectively certain, the areas of the second color sub-pixel block 112 and the third color sub-pixel block 113 are increased, thereby improving the utilization rate of the space within the first virtual rectangle. Furthermore, since the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled pentagons, relative to the case where the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled symmetrical pentagons, the area where the second hypotenuse 192 of the second color sub-pixel block 112 and the third color sub-pixel block 113 are located can further increase the area of ​​the second color sub-pixel block 112 and the third color sub-pixel block 113, thereby further improving the utilization rate of the space within the first virtual rectangle; relative to the case where the shapes of the second color sub-pixel block 112 and the third color sub-pixel block 113 are both right-angled trapezoids, the second hypotenuse 192 of the second color sub-pixel block 112 and the third color sub-pixel block 113 can reduce the difficulty of manufacturing, and when the process level is low, the shape of the second color sub-pixel block and the third color sub-pixel block can adopt a right-angled pentagon.

[0064] For example, the ratio of the length of the orthographic projection of the first oblique side 191 in the first direction to the length of the orthographic projection of the second oblique side 192 in the first direction is in the range of 2 to 6. Thus, the brightness center of the third color sub-pixel block can be closer to the first color sub-pixel block, thereby reducing the risk of color separation.

[0065] For example, in some examples, such as Figure 3As shown, the shape of the first color sub-pixel block 111 is a right-angled symmetrical pentagon, the right-angled symmetrical pentagon is symmetrical about the perpendicular bisector of the first side, and the base of the right-angled symmetrical pentagon is parallel to the first side or located on the first side, and is farther away from the first side relative to the vertex of the right-angled symmetrical pentagon in the direction perpendicular to the first side, the right-angled symmetrical pentagon includes a third hypotenuse 193 and a fourth hypotenuse 194 passing through the vertex of the right-angled symmetrical pentagon, the third hypotenuse 193 and the fourth hypotenuse 194 have the same length, the third hypotenuse 193 of the first color sub-pixel block 111 is parallel to the first hypotenuse 191 of the second color sub-pixel block 112 and the spacing is the first distance, the fourth hypotenuse 194 of the first color sub-pixel block 111 is parallel to the first hypotenuse 191 of the third color sub-pixel block 113 and the spacing is the second distance. It should be noted that the above-mentioned parallel includes the situation of being approximately parallel, and the above-mentioned distance refers to the minimum distance.

[0066] For example, in some examples, such as Figure 3 As shown, in the first virtual rectangle 110 and the second virtual rectangle 120, the third color sub-pixel block 113 is closer to the center of the minimum repeating area 100 than the second color sub-pixel block 112, and in the third virtual rectangle 130 and the fourth virtual rectangle 140, the second color sub-pixel block 112 is closer to the center of the minimum repeating area 100 than the third color sub-pixel block 113, the third color sub-pixel block 113 in the first virtual rectangle 110 is adjacent to the second color sub-pixel block 112 in the fourth virtual rectangle 140, and the second virtual rectangle 130 and the fourth virtual rectangle 140 are adjacent to each other. 120 is adjacent to the second color sub-pixel block 112 in the third virtual rectangle 130, the second hypotenuse 192 of the third color sub-pixel block 113 in the first virtual rectangle 110 is parallel to the second hypotenuse 192 of the second color sub-pixel block 112 in the fourth virtual rectangle 140 and the spacing is the third distance, the second hypotenuse 192 of the third color sub-pixel block 113 in the second virtual rectangle 120 is parallel to the second hypotenuse 192 of the second color sub-pixel block 112 in the third virtual rectangle 130 and the spacing is the fourth distance.

[0067] For example, in some examples, the first distance, the second distance, the third distance, and the fourth distance are all equal, thereby improving the utilization rate of process precision.

[0068] Figure 4 A schematic diagram of another pixel arrangement structure provided according to an embodiment of the present disclosure. Figure 4 Two minimal repeat regions 100 are shown, such as Figure 4As shown, in the same minimum repeat area 100, the second color sub-pixel block 112 of the first virtual rectangle 110 and the second color sub-pixel block 112 of the second virtual rectangle 120 are merged into the same sub-pixel, that is, the second merged sub-pixel block; in two minimum repeat areas 100 adjacent in the second direction, the two minimum repeat areas 100 adjacent in the second direction include the first minimum repeat area 1001 and the second minimum repeat area 1002 sequentially arranged along the second direction, and the second color sub-pixel block 112 of the fourth virtual rectangle 140 of the first minimum repeat area 1001 and the second color sub-pixel block 112 of the third virtual rectangle 130 of the second minimum repeat area 1002 are merged into the same sub-pixel, that is, the second merged sub-pixel block. Thus, the second color sub-pixel block merged into the same sub-pixel can reduce the difficulty of the manufacturing process of the second color sub-pixel block. In addition, when the pixel arrangement structure is used for a display panel, a sub-pixel rendering (Sub-Pixel Rendering, SPR) algorithm can be used for driving, so as to realize virtual display.

[0069] It is worth noting that the second color sub-pixel block of the first virtual rectangle and the second color sub-pixel block of the second virtual rectangle in the same minimum repeating area of ​​the same sub-pixel or the second color sub-pixel block of the fourth virtual rectangle in the first minimum repeating area of ​​the same sub-pixel and the second color sub-pixel block of the third virtual rectangle in the second minimum repeating area of ​​the same sub-pixel are driven to emit light as the same sub-pixel. In other words, the second color sub-pixel blocks in different virtual rectangles that are merged into the same sub-pixel are only a part of a sub-pixel, and the center of this integrated sub-pixel is located on the first side or on the shared side of two adjacent minimum repeating areas in the second direction.

[0070] For example, when the second color sub-pixel block is a right-angled symmetrical pentagon, the shape of the second merged sub-pixel block is a hexagon.

[0071] For example, in some examples, such as Figure 4As shown, in the same minimum repeat area 100, the third color sub-pixel block 113 of the first virtual rectangle 110 and the third color sub-pixel block 113 of the second virtual rectangle 120 are merged into the same sub-pixel, that is, the third merged sub-pixel block; in two minimum repeat areas 100 adjacent in the second direction, the two minimum repeat areas 100 adjacent in the second direction include the first minimum repeat area 1001 and the second minimum repeat area 1002 sequentially arranged along the second direction, and the third color sub-pixel block 113 of the fourth virtual rectangle 140 of the first minimum repeat area 1001 and the third color sub-pixel block 113 of the third virtual rectangle 130 of the second minimum repeat area 1002 are merged into the same sub-pixel, that is, the third merged sub-pixel block. Thus, the third color sub-pixel block merged into the same sub-pixel can reduce the difficulty of the manufacturing process of the third color sub-pixel block. In addition, when the pixel arrangement structure is used for a display panel, a sub-pixel rendering (Sub-Pixel Rendering, SPR) algorithm can be used for driving, thereby realizing virtual display.

[0072] It is worth noting that the third color sub-pixel block of the first virtual rectangle and the third color sub-pixel block of the second virtual rectangle in the same minimum repeating area of ​​the same sub-pixel or the third color sub-pixel block of the fourth virtual rectangle in the first minimum repeating area of ​​the same sub-pixel and the third color sub-pixel block of the second virtual rectangle in the second minimum repeating area are driven to emit light as the same sub-pixel. In other words, the third color sub-pixel blocks located in different virtual rectangles that are merged into the same sub-pixel are only a part of a sub-pixel, and the center of this integrated sub-pixel is located on the first side or on the shared side of two adjacent minimum repeating areas in the second direction.

[0073] In addition, in the same minimum repeating region 100, the second color sub-pixel block 112 of the first virtual rectangle 110 and the second color sub-pixel block 112 of the second virtual rectangle 120 may not be merged into the same sub-pixel; in two minimum repeating regions 100 adjacent in the second direction, the two minimum repeating regions 100 adjacent in the second direction include the first minimum repeating region 1001 and the second minimum repeating region 1002 sequentially arranged along the second direction, and the second color sub-pixel block 112 of the fourth virtual rectangle 140 of the first minimum repeating region 1001 and the second color sub-pixel block 112 of the third virtual rectangle 130 of the second minimum repeating region 1002 may not be merged into the same sub-pixel. In this case, the second color sub-pixel block 112 of the first virtual rectangle 110 and the second color sub-pixel block 112 of the second virtual rectangle 120 are driven to emit light as two second color sub-pixel blocks, and in the sub-pixel patterning process, they can share the same single color graphic area, that is, a continuous graphic. The second color sub-pixel block 112 of the fourth virtual rectangle 140 of the first minimum repeating area 1001 and the second color sub-pixel block 112 of the third virtual rectangle 130 of the second minimum repeating area 1002 are driven to emit light respectively as two second color sub-pixel blocks, and in the sub-pixel patterning process, they can share the same single color graphic area, that is, a continuous graphic.

[0074] In addition, in the same minimum repeating region 100, the third color sub-pixel block 113 of the first virtual rectangle 110 and the third color sub-pixel block 113 of the second virtual rectangle 120 may not be merged into the same sub-pixel; in two minimum repeating regions 100 adjacent in the second direction, the two minimum repeating regions 100 adjacent in the second direction include the first minimum repeating region 1001 and the second minimum repeating region 1002 sequentially arranged along the second direction, and the third color sub-pixel block 113 of the fourth virtual rectangle 140 of the first minimum repeating region 1001 and the third color sub-pixel block 113 of the third virtual rectangle 130 of the second minimum repeating region 1002 may not be merged into the same sub-pixel. In this case, the third color sub-pixel block 113 of the first virtual rectangle 110 and the third color sub-pixel block 113 of the second virtual rectangle 120 are driven to emit light as two third color sub-pixel blocks, and in the sub-pixel patterning process, they may share the same single color pattern area. The third color sub-pixel block 113 of the fourth virtual rectangle 140 of the first minimum repeating area 1001 and the third color sub-pixel block 113 of the third virtual rectangle 130 of the second minimum repeating area 1002 are driven to emit light as two third color sub-pixel blocks respectively, and can share the same single color pattern area in the sub-pixel patterning process. For example, in some examples, such as Figure 4As shown, in the same minimum repeating area 100, the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color sub-pixel block 111 of the fourth virtual rectangle 140 share the same single color graphic area in the sub-pixel patterning process. For example, when the pixel arrangement structure is applied to an organic light-emitting display device, the sub-pixel patterning process includes an evaporation process, and the light-emitting layer of the first color sub-pixel block 111 of the third virtual rectangle 130 and the light-emitting layer of the first color sub-pixel block 111 of the fourth virtual rectangle 140 can be formed by using the same mask opening. Of course, the above-mentioned sub-pixel patterning process includes but is not limited to the evaporation process, and may also include printing, color filter patterning process, etc. Therefore, the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color sub-pixel block 111 of the fourth virtual rectangle 140 share the same single color graphic area in the sub-pixel patterning process such as printing and color filter patterning process.

[0075] In some examples, the shape of at least one of the second merged sub-pixel block and the third merged sub-pixel block includes a parallel edge group that is substantially parallel to the second direction, and of the two parallel edges in the parallel edge group, the parallel edge of the first sub-pixel block that is closer to the merged sub-pixel block where it is located and adjacent in the first direction is a first parallel edge, and the parallel edge of the first sub-pixel block that is farther from the merged sub-pixel block where it is located and adjacent in the first direction is a second parallel edge, and the length of the first parallel edge is less than the length of the second parallel edge.

[0076] In some examples, a shape of at least one of the second merged sub-pixel block and the third merged sub-pixel block includes a hexagon, the hexagon including a parallel edge group including two parallel edges, a first relative edge group including two relative edges, and a second relative edge group including two relative edges, the two relative edges in the first relative edge group are oppositely arranged, the two relative edges in the second relative edge group are oppositely arranged, and the lengths of the two parallel edges in the parallel edge group are different.

[0077] In some examples, the hexagon is axisymmetric about a line parallel to the first direction.

[0078] In some examples, the shape of at least one of the second merged sub-pixel block and the third merged sub-pixel block includes a polygon and includes two vertices that are farthest apart in the second direction, and a vertex line connecting the two farthest vertices is substantially parallel to the second direction.

[0079] In some examples, the length of the parallel side of the two parallel sides in the parallel side group that is closer to the first sub-pixel block is shorter than the length of the parallel side of the two parallel sides in the parallel side group that is farther from the first sub-pixel block.

[0080] In some examples, in the pixel arrangement structure provided by an embodiment of the present disclosure, the shape of at least one of the second merged sub-pixel block and the third merged sub-pixel block is divided by a line connecting two vertices arranged in the second direction into a first part close to the first sub-pixel block in the first direction and a second part away from the first sub-pixel block in the first direction, and the width of the first part in the first direction is greater than the width of the second part in the first direction.

[0081] For example, in some examples, such as Figure 4 As shown, the organic light-emitting layer of the first color sub-pixel block 111 of the third virtual rectangle 130 and the organic light-emitting layer of the first color sub-pixel block 111 of the fourth virtual rectangle 140 are evaporated using the same opening on the fine metal mask.

[0082] For example, in some examples, such as Figure 4 As shown, in two minimum repeating areas 100 adjacent to each other in the second direction, the two minimum repeating areas 100 adjacent to each other in the second direction include a first minimum repeating area 1001 and a second minimum repeating area 1002 sequentially arranged along the second direction, and a first color sub-pixel block 111 of a first virtual rectangle 110 of the first minimum repeating area 1001 and a first color sub-pixel block 111 of a second virtual rectangle 120 of the second minimum repeating area 1002 share the same single color graphic area in the sub-pixel graphic process. For example, when the pixel arrangement structure is applied to an organic light-emitting display device, the sub-pixel patterning process includes an evaporation process, and the light-emitting layer of the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the light-emitting layer of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 can be formed by using the same mask plate opening, that is, the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 include a light-emitting layer formed by using the same mask plate opening. Of course, the above-mentioned sub-pixel patterning process includes but is not limited to the evaporation process, and may also include printing, color filter patterning process, etc. Therefore, the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 share the same single color graphic area in the sub-pixel patterning process such as printing and color filter patterning process. Therefore, the third color sub-pixel blocks that are combined into the same sub-pixel can reduce the difficulty of the manufacturing process of the third color sub-pixel blocks.

[0083] For example, in some examples, such as Figure 4As shown, in the same minimum repeating area 100, the distance between the center of the second color sub-pixel block 112 in the first virtual rectangle 110 and the center of the third color sub-pixel block 113 is in the range of 5 / 9-7 / 9 of the length of the first side length, thereby ensuring that the distance between the third color sub-pixel block 113 of the first virtual rectangle 110 and the second virtual rectangle 120 and the second color sub-pixel block 112 of the first virtual rectangle 110 and the second virtual rectangle 120 of the adjacent minimum repeating area in the first direction is large enough, thereby facilitating the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color sub-pixel block 111 of the fourth virtual rectangle 140 in the same minimum repeating area 100 to be formed by using the same mask plate opening, and the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 to be formed by using the same mask plate opening, thereby reducing the process difficulty.

[0084] Figure 5 A pixel arrangement structure is provided according to an embodiment of the present disclosure. Figure 5 As shown, the first color sub-pixel block 111 in the third virtual rectangle 130 and the fourth virtual rectangle 140 is positioned as the fourth color sub-pixel 114 .

[0085] For example, the first color sub-pixel block 111 includes green sub-pixels, and the fourth color sub-pixel 114 includes yellow sub-pixels. Thus, the pixel arrangement structure can adopt a red, green, blue, and yellow (RGBY) four-color mode, thereby further improving the display quality of the pixel arrangement structure.

[0086] Figure 6 A pixel arrangement structure is provided according to an embodiment of the present disclosure. Figure 6 As shown, the first color sub-pixel block 111 in the first virtual rectangle 110 and the fourth virtual rectangle 140 is positioned as the fifth color sub-pixel 115 .

[0087] For example, the first color sub-pixel block 110 includes green sub-pixels, and the fifth color sub-pixel 115 includes white sub-pixels. Thus, the pixel arrangement structure can adopt a red, green, blue, and white (RGBW) mode, thereby effectively improving the brightness of the pixel arrangement structure and improving energy utilization efficiency.

[0088] An embodiment of the present disclosure further provides a display substrate. Figure 7 A display substrate is provided according to an embodiment of the present disclosure.

Fig. 9 A display substrate provided according to an embodiment of the present disclosure Figure 8 Schematic diagram of the cross section along the A-A' direction. Figure 8 As shown, the first color sub-pixel block 111 includes a first color pixel electrode 1110 and a first color light-emitting layer 1111 disposed on the first color pixel electrode 1110, the second color sub-pixel block 112 includes a second color pixel electrode 1120 and a second color light-emitting layer 1121 disposed on the second color pixel electrode 1120, and the third color sub-pixel block 113 includes a third color pixel electrode 1130 and a third color light-emitting layer 1131 disposed on the third color pixel electrode 1130. Thus, the display substrate can be an array substrate.

[0090] For example, in some examples, the first color pixel electrode 1110 is configured to drive the first color light emitting layer 1111 to emit light.

[0091] For example, the shape of the first color pixel electrode 1110 may be the same as the shape of the first color sub-pixel block 111. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the first color pixel electrode 1110 may be different from the shape of the first color sub-pixel block 111, and the shape of the first color sub-pixel block 111 may be defined by the pixel defining layer.

[0092] It should be noted that the shape of the first color sub-pixel block is the shape of the light-emitting area of ​​the first color sub-pixel block. In addition, the specific shape of the first color light-emitting layer can be set according to the manufacturing process, and the embodiment of the present disclosure is not limited here. For example, the shape of the first color light-emitting layer can be determined by the shape of the mask opening in the manufacturing process.

[0093] For example, in some examples, the second color pixel electrode 1120 is configured to drive the second color light emitting layer 1121 to emit light.

[0094] For example, the shape of the second color pixel electrode 1120 may be the same as the shape of the second color sub-pixel block 112. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the second color pixel electrode 1120 may be different from the shape of the first color sub-pixel block 112, and the shape of the second color sub-pixel block 112 may be defined by the pixel defining layer.

[0095] It should be noted that the shape of the second color sub-pixel block is the shape of the light-emitting area of ​​the second color sub-pixel block. In addition, the specific shape of the second color light-emitting layer can be set according to the preparation process, and the embodiment of the present disclosure is not limited here. For example, the shape of the second color light-emitting layer can be determined by the shape of the mask opening in the preparation process.

[0096] For example, in some examples, the shape of the third color pixel electrode 1130 is configured to drive the third color light emitting layer 1131 to emit light.

[0097] For example, the shape of the third color pixel electrode 1130 may be the same as the shape of the third color sub-pixel block 113. Of course, the embodiments of the present disclosure include but are not limited to this, and the shape of the third color pixel electrode 1130 may be different from the shape of the third color sub-pixel block 113, and the shape of the third color sub-pixel block 113 may be defined by the pixel defining layer.

[0098] It should be noted that the shape of the third color sub-pixel block is the shape of the light-emitting area of ​​the third color sub-pixel block. In addition, the specific shape of the third color light-emitting layer can be set according to the manufacturing process, and the embodiment of the present disclosure is not limited here. For example, the shape of the third color light-emitting layer can be determined by the shape of the mask opening in the manufacturing process.

[0099] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in the same minimum repeating area 100, the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the fourth virtual rectangle 140 can be formed by sharing the same color single color graphic area, for example, by using the same mask template opening.

[0100] For example, in some examples, the area of ​​the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the fourth virtual rectangle 140 formed by sharing the same single color graphic area is greater than the sum of the area of ​​the first color pixel electrode 1110 of the first color sub-pixel block 111 of the third virtual rectangle 130 and the area of ​​the first color pixel electrode 1110 of the first color sub-pixel block 111 of the fourth virtual rectangle 140.

[0101] For example, in some examples, because the distance between the center of the first color sub-pixel block 111 of the third virtual rectangle 130 and the center of the first color sub-pixel block 111 of the fourth virtual rectangle 140 is greater than 1 / 2 of the length of the second side 1102, the area of ​​the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the fourth virtual rectangle 140 formed by sharing the same single color graphic area is greater than 1.5 times the sum of the areas of the first color pixel electrode 1110 of the first color sub-pixel block 111 of the third virtual rectangle 130 and the first color pixel electrode 1110 of the first color sub-pixel block 111 of the fourth virtual rectangle 140.

[0102] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in two minimum repeating areas 100 adjacent to each other in the second direction, the two minimum repeating areas 100 adjacent to each other in the second direction include a first minimum repeating area 1001 and a second minimum repeating area 1002 sequentially arranged along the second direction, and a first color light-emitting layer 1111 of a first color sub-pixel block 111 of a first virtual rectangle 110 of the first minimum repeating area 1001 and a first color light-emitting layer 1111 of a first color sub-pixel block 111 of a second virtual rectangle 120 of the second minimum repeating area 1002 are formed by sharing a same color single color graphic area, for example, by using a same mask template opening.

[0103] For example, in some examples, the areas of the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 formed by sharing the same single color graphic area are greater than the sum of the areas of the first color pixel electrode 1110 of the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color pixel electrode 1110 of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002.

[0104] For example, since the distance between the center of the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the center of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 is greater than 1 / 2 of the length of the second side 1102, the area of ​​the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the first virtual rectangle 110 and the first color light-emitting layer 1111 of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002 formed by sharing the same single color graphic area is greater than 1.5 times the sum of the areas of the first color pixel electrode 1110 of the first color sub-pixel block 111 of the first virtual rectangle 110 of the first minimum repeating area 1001 and the first color pixel electrode 1110 of the first color sub-pixel block 111 of the second virtual rectangle 120 of the second minimum repeating area 1002.

[0105] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in the same minimum repeating area 100, the second color pixel electrode 1120 of the second color sub-pixel block 112 of the first virtual rectangle 110 and the second color pixel electrode 1120 of the second color sub-pixel block 112 of the second virtual rectangle 120 are merged into the same pixel electrode, thereby loading the data signal as one pixel electrode.

[0106] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in two minimum repeating areas 100 adjacent to each other in the second direction, the two minimum repeating areas 100 adjacent to each other in the second direction include a first minimum repeating area 1001 and a second minimum repeating area 1002 sequentially arranged along the second direction, and a second color pixel electrode 1120 of a second color sub-pixel block 112 of a fourth virtual rectangle 140 of the first minimum repeating area 1001 and a second color pixel electrode 1120 of a second color sub-pixel block 112 of a third virtual rectangle 130 of the second minimum repeating area 1002 are merged into the same pixel electrode, i.e., an integrated pixel electrode, so as to load a data signal as one pixel electrode.

[0107] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in the same minimum repeating area 100, the third color pixel electrode 1130 of the third color sub-pixel block 113 of the first virtual rectangle 110 and the third color pixel electrode 1130 of the third color sub-pixel block 113 of the second virtual rectangle 120 are merged into the same pixel electrode, that is, an integrated pixel electrode, so as to load the data signal as one pixel electrode.

[0108] For example, in some examples, such as Figure 8 and Fig. 9 As shown, in two minimum repeating areas 100 adjacent to each other in the second direction, the two minimum repeating areas 100 adjacent to each other in the second direction include a first minimum repeating area 1001 and a second minimum repeating area 1002 sequentially arranged along the second direction, and a third color pixel electrode 1130 of a third color sub-pixel block 113 of a fourth virtual rectangle 140 of the first minimum repeating area 1001 and a third color pixel electrode 1130 of a third color sub-pixel block 113 of a third virtual rectangle 130 of the second minimum repeating area 1002 are merged into the same sub-pixel, so as to be used as a pixel electrode to load a data signal.

[0109] Fig.10 Another display substrate provided according to an embodiment of the present disclosure is Figure 8 Schematic diagram of the cross section along the A-A' direction. Fig. 9 As shown, the first color sub-pixel block 111 includes a first color filter 1112, the second color sub-pixel block 112 includes a second color filter 1122, and the third color sub-pixel block 113 includes a third color filter 1132. Thus, the display substrate can be a color filter substrate. It should be noted that when the display substrate is a color filter substrate, it can be used not only for liquid crystal display panels, but also for display panels using white light OLED combined with color filter mode.

[0110] For example, in some examples, such as Fig.10 As shown, the display substrate further includes a black matrix 140 disposed between the first color filter 1112 , the second color filter 1122 and the third color filter 1132 .

Therefore, the resolution of the display device can be improved, and a display device with real high resolution can be provided. In addition, since the pixel arrangement structure has better symmetry, the display effect of the display device is better.

[0112] For example, in some examples, the display device may be any product or component with a display function, such as a smart phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or the like.

[0113] An embodiment of the present disclosure further provides a mask plate, which is used to form the pixel arrangement structure provided by any of the above examples.

[0114] For example, the mask may include a first mask for forming a first color sub-pixel block, a second mask for forming a second color sub-pixel block, and a third mask for forming a third color sub-pixel block, that is, the mask is an evaporation mask.

[0115] For example, a first opening may be set on the first mask plate to form a light-emitting layer of a first color sub-pixel block in the evaporation process; a second opening may be set on the second mask plate to form a light-emitting layer of a second color sub-pixel block in the evaporation process; and a third opening may be set on the third mask plate to form a light-emitting layer of a third color sub-pixel block in the evaporation process.
