Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] The inventors discovered the following problems in the related technologies: As display panels continue to evolve towards higher resolution and higher refresh rates, end users are increasingly demanding higher color fidelity and edge sharpness in display image quality. Existing mainstream pixel arrangement architectures, such as RGB strip arrangements and Diamond pixel arrangements, all suffer from the spatial layout of sub-pixels lacking certain color sub-pixels in specific directions. Since the formation of a white display effect depends on the combined participation and light mixing of red, green, and blue sub-pixels, the lack of sub-pixel types in any of these directions will prevent the construction of complete white light synthesis conditions when displaying colored lines or image edges, thus inducing significant color shift and color fringing phenomena. These defects are particularly prominent when displaying fine textures, text edges, or highly saturated color graphics, restricting the imaging quality of display panels and user experience.

[0037] In view of this, embodiments of this application provide a pixel arrangement structure and its display panel. The specific implementation of the embodiments of this application will be further described below with reference to the accompanying drawings.

[0038] Specifically, refer to Figures 1 to 8As shown, a first aspect of this application provides a pixel arrangement structure 10, wherein the pixel arrangement structure 10 includes a plurality of repeating units 11 arranged along a first direction X and a second direction Y. The repeating unit 11 is the smallest structural unit in the pixel arrangement structure 10 with a periodic repetition pattern. The plurality of repeating units 11 are arranged in an array along the first direction X and the second direction Y to collectively constitute a complete pixel arrangement structure 10. It should be noted that... Figures 1 to 8 A repeating unit 11 is schematically marked with a dashed box in the middle. Its purpose is to clearly show the boundary range of the repeating unit 11. The dashed box does not constitute a limitation on the actual physical structure of the repeating unit 11.

[0039] like Figure 1 and Figure 2 As shown, the repeating unit 11 includes at least two pixel units. In this embodiment, exemplarily, the repeating unit 11 includes a first pixel unit 111, a second pixel unit 112, a third pixel unit 113, and a fourth pixel unit 114. Each pixel unit includes a plurality of spaced-apart sub-pixels 12. Within the same pixel unit, the sub-pixels 12 include a first sub-pixel 121, a second sub-pixel 122, and a third sub-pixel 123, each with a different color. Optionally, the first sub-pixel 121 is a red sub-pixel, the second sub-pixel 122 is a green sub-pixel, and the third sub-pixel 123 is a blue sub-pixel. However, this application is not limited to this; in other embodiments, the colors of the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 may also be other color combinations.

[0040] like Figure 2 As shown, in two adjacent pixel units, one is obtained by rotating the other by a preset angle along the rotation direction, where the preset angle is less than 360°. Through the above rotational arrangement, a dense and uniform distribution of sub-pixels 12 is achieved within a limited space, providing a structural basis for the integrity of color components in all directions.

[0041] Continue reading Figure 1 and Figure 2 The first direction X is perpendicular to the second direction Y, and the third direction Z intersects the first direction X and the second direction Y. A first sub-pixel 121, a second sub-pixel 122, and a third sub-pixel 123 are arranged along the first direction X, the second direction Y, and the third direction Z. That is, regardless of whether it is in the horizontal direction (first direction X), the vertical direction (second direction Y), or the diagonal direction (third direction Z), the pixel arrangement structure 10 provided in this embodiment simultaneously has sub-pixels 12 of three colors: red, green, and blue.

[0042] This application embodiment sets adjacent pixel units to rotate and arrange them at a preset angle, so that three different colors of sub-pixels exist simultaneously in the horizontal (first direction X), vertical (second direction Y) and diagonal (third direction Z) directions, thereby achieving complete synthesis of white light, effectively avoiding color shift or color edge phenomenon caused by the absence of a certain color sub-pixel in a certain direction, and significantly improving display quality.

[0043] Further, please refer to Figure 1 and Figure 2 In this embodiment, the repeating unit 11 includes a first pixel unit 111, a second pixel unit 112, a third pixel unit 113, and a fourth pixel unit 114 arranged in an array along the first direction X and the second direction Y. The first pixel unit 111, the second pixel unit 112, the third pixel unit 113, and the fourth pixel unit 114 are arranged around the geometric center of the repeating unit 11. Specifically, the four pixel units are arranged in a 2×2 matrix, that is: the first pixel unit 111 is located in the upper left region of the repeating unit 11, the second pixel unit 112 is located in the lower left region of the repeating unit 11, the third pixel unit 113 is located in the upper right region of the repeating unit 11, and the fourth pixel unit 114 is located in the lower right region of the repeating unit 11. The four pixel units together enclose the geometric center of the repeating unit 11, which is also the location of the common corner point of the four pixel units.

[0044] By arranging the first pixel unit 111, the second pixel unit 112, the third pixel unit 113, and the fourth pixel unit 114 around the geometric center of the repeating unit 11, the relative positional relationship between each pixel unit is clear and symmetrical. This not only benefits the design and manufacturing of the mask, but also facilitates the uniform distribution and continuous transition of the sub-pixels 12 at the boundary of the repeating unit 11, avoiding the display unevenness (Mura) phenomenon caused by uneven arrangement, and improving the brightness uniformity and color uniformity of the display panel.

[0045] Furthermore, in this embodiment, the second pixel unit 112 is located on one side of the first pixel unit 111 in the second direction Y (i.e., above or below the first pixel unit 111). Figure 1 and Figure 2 (In the orientation shown, it is below), the third pixel unit 113 is located on one side of the first pixel unit 111 in the first direction X (i.e., to the left or right of the first pixel unit 111, in Figure 1 and Figure 2 (The orientation shown is to the right). The fourth pixel unit 114 is located on one side of the second pixel unit 112 in the first direction X (i.e., to the left or right of the second pixel unit 112). Figure 1 and Figure 2 (Right side in the indicated direction).

[0046] Specifically, the second pixel unit 112 is obtained by rotating the first pixel unit 111 along the rotation direction by a first preset angle, where the first preset angle is 180°. In other words, the arrangement of each sub-pixel 12 in the second pixel unit 112 is equivalent to the arrangement after rotating the first pixel unit 111 as a whole by 180° in the plane. The third pixel unit 113 is obtained by rotating the first pixel unit 111 along the rotation direction by a second preset angle, where the second preset angle is 90°. In other words, the arrangement of each sub-pixel 12 in the third pixel unit 113 is equivalent to the arrangement after rotating the first pixel unit 111 as a whole by 90° in the plane. The fourth pixel unit 114 is obtained by rotating the first pixel unit 111 along the rotation direction by a third preset angle, where the third preset angle is 270°. In other words, the arrangement of each sub-pixel 12 in the fourth pixel unit 114 is equivalent to the arrangement after rotating the first pixel unit 111 as a whole by 270° in the plane.

[0047] The rotation direction mentioned above is counterclockwise. That is, the first pixel unit 111 is the basic unit, the second pixel unit 112 is obtained by rotating the first pixel unit 111 counterclockwise by 180°, the third pixel unit 113 is obtained by rotating the first pixel unit 111 counterclockwise by 90°, and the fourth pixel unit 114 is obtained by rotating the first pixel unit 111 counterclockwise by 270°.

[0048] In other embodiments of this application, the rotation direction can also be clockwise, as long as the relative rotation angle relationship between the four pixel units remains unchanged. That is, when the rotation direction is clockwise, the second pixel unit 112 is obtained by rotating the first pixel unit 111 clockwise by 180°, the third pixel unit 113 is obtained by rotating the first pixel unit 111 clockwise by 270°, and the fourth pixel unit 114 is obtained by rotating the first pixel unit 111 clockwise by 90°.

[0049] This embodiment simplifies the design and manufacturing process of the pixel arrangement structure 10 by setting a specific rotation angle and direction, thus establishing a defined geometric transformation relationship between the four pixel units in the repeating unit 11. Simultaneously, a 180° rotation makes the second pixel unit 112 centrally symmetrical with the first pixel unit 111, and a 90° / 270° rotation makes the third pixel unit 113 and the fourth pixel unit 114 rotationally symmetrical. This combination of multiple symmetry relationships facilitates the uniform distribution of sub-pixels 12 within the repeating unit 11, further improving display uniformity.

[0050] Please see Figures 1 to 5In this embodiment, the pixel unit is rectangular. Within the same pixel unit, the third sub-pixel 123 is a continuous pattern, and the two ends of the third sub-pixel 123 are respectively disposed at the two corner regions of the pixel unit, which are diagonally arranged. The third sub-pixel 123 and the pixel unit enclose two mutually spaced and non-connected receiving areas 14. The first sub-pixel 121 is disposed in one of the receiving areas 14, and the second sub-pixel 122 is disposed in the other receiving area 14.

[0051] like Figures 1 to 3 In this embodiment, taking the first pixel unit 111 as an example, the continuous third sub-pixels 123 are generally Z-shaped. One end of the third sub-pixel 123 extends to the upper right corner region 13 of the first pixel unit 111, and the other end extends to the lower left corner region 13 of the first pixel unit 111. The Z-shaped third sub-pixel 123 includes a first part and two second parts. Within the first pixel unit 111, the first part of the third sub-pixel 123 extends along the first direction X, and the geometric center of the first part overlaps with the geometric center of the first pixel unit 111. The two second parts of the third sub-pixel 123 extend from both ends of the first part along the second direction Y, and the two second parts are respectively located in the upper right corner region 13 and the lower left corner region 13 of the first pixel unit 111. The first and second parts of the third sub-pixel 123, together with the four sides of the rectangular first pixel unit 111, form two spaced-apart receiving areas 14. One receiving area 14 is located in the upper left corner region 13 of the first pixel unit 111, and the other receiving area 14 is located in the lower right corner region of the first pixel unit 111. The first sub-pixel 121 is rectangular and is located within the receiving area 14 in the upper left corner of the first pixel unit 111. The second sub-pixel is also rectangular and is located within the receiving area 14 in the lower right corner of the first pixel unit 111. The rectangular sub-pixel has a regular shape and straight boundaries, which is beneficial for the design of the mask aperture and the precision control of the vapor deposition process, thereby reducing manufacturing difficulty and improving product yield.

[0052] Optionally, the third sub-pixel 123 surrounds at least a portion of the first sub-pixel 121 and a portion of the second sub-pixel 122. That is, the positions of the first sub-pixel 121 and the second sub-pixel 122 within the pixel unit are not completely independent of the third sub-pixel 123, but are partially embedded within the spatial region enclosed by the third sub-pixel 123, such that the third sub-pixel 123 forms at least a partial surrounding or enclosing relationship with the first sub-pixel 121 and the second sub-pixel 122. This "enclosing" layout can effectively improve the utilization rate of the internal space of the pixel unit, achieving a larger area of ​​sub-pixels 12 within a limited pixel unit area.

[0053] Furthermore, such as Figure 5As shown, in other embodiments of this application, taking the first pixel unit 111 as an example, the continuous third sub-pixels 123 are generally Z-shaped. One end of the third sub-pixel 123 extends to the upper left corner region 13 of the first pixel unit 111, and the other end extends to the lower right corner region 13 of the first pixel unit 111. The Z-shaped third sub-pixel 123 includes a first part and two second parts. Within the first pixel unit 111, the first part of the third sub-pixel 123 extends along the third direction Z, and the geometric center of the first part overlaps with the geometric center of the first pixel unit 111. The two second parts of the third sub-pixel 123 extend from both ends of the first part along the second direction Y to the edge of the first pixel unit 111. The first part and the second part of the third sub-pixel 123, together with the four sides of the rectangular first pixel unit 111, form two mutually spaced receiving areas 14. The first sub-pixel 121 is disposed in one of the receiving areas 14, and the second sub-pixel 122 is disposed in the other receiving area 14. The first sub-pixel 121 and the second sub-pixel 122 are both right-angled triangles, and they are completely embedded in the space enclosed by the third sub-pixel 123, so that the third sub-pixel 123 forms at least a partial surrounding or enclosing relationship with the first sub-pixel 121 and the second sub-pixel 122. This "enclosing" layout can effectively improve the utilization rate of the internal space of the pixel unit, and achieve a larger area of ​​sub-pixels 12 within the limited pixel unit area.

[0054] Optionally, the first sub-pixel 121 is a red sub-pixel, the second sub-pixel 122 is a green sub-pixel, and the third sub-pixel 123 is a blue sub-pixel.

[0055] In some variations of this embodiment, the third sub-pixel 123 is not limited to a Z-shape, but can also be an S-shape, an L-shape, or other irregular shape with at least one bent portion.

[0056] Furthermore, such as Figure 2As shown, in this embodiment, within the same pixel unit, the area ratio of the first sub-pixel 121 to the third sub-pixel 123 ranges from 1:1.8 to 1:2.5. The area ratio of the second sub-pixel 122 to the third sub-pixel 123 also ranges from 1:1.8 to 1:2.5. In this embodiment, the first sub-pixel 121 is a red sub-pixel, the second sub-pixel 122 is a green sub-pixel, and the third sub-pixel 123 is a blue sub-pixel. For example, the area ratio of the first sub-pixel 121 (red sub-pixel) to the third sub-pixel 123 (blue sub-pixel) can be: 1:1.9, 1:2, 1:2.1, 1:2.2, 1:2.3, or 1:2.4. The area ratio of the second sub-pixel 122 (green sub-pixel) to the third sub-pixel 123 (green sub-pixel) can be: 1:1.9, 1:2, 1:2.1, 1:2.2, 1:2.3, or 1:2.4. When the area of ​​the third sub-pixel 123 (blue sub-pixel) is designed to be 1.8 to 2.5 times the area of ​​the first sub-pixel 121 (red sub-pixel) or the second sub-pixel 122 (green sub-pixel), the lifespan of the blue sub-pixel can be improved to the maximum extent while ensuring the color gamut and color balance of the display panel. If the area of ​​the third sub-pixel 123 is less than the lower limit of the above range (i.e., less than 1.8 times), the improvement effect on the lifespan of the blue sub-pixel is not significant; if the area of ​​the third sub-pixel 123 is greater than the upper limit of the above range (i.e., greater than 2.5 times), it may lead to the red or green sub-pixel having too small an area, affecting its luminous efficiency and color performance, and may even lead to a decrease in display brightness or a reduction in color gamut due to insufficient aperture ratio of red or green sub-pixels.

[0057] In a preferred embodiment, the first sub-pixel 121 and the second sub-pixel 122 have equal areas. Since the lifespan characteristics of red and green luminescent materials are similar, setting the red and green sub-pixels to have equal areas facilitates the use of the same design parameters in the driving circuit, simplifies the design and debugging process of the driving circuit, and also helps to maintain the brightness and chromaticity balance of the red and green light emission.

[0058] In a further preferred embodiment, the area ratio of the first sub-pixel 121 to the third sub-pixel 123 is 1:2. That is, the area of ​​the blue sub-pixel is exactly twice the area of ​​the red sub-pixel, and the area ratio of the second sub-pixel 122 to the third sub-pixel 123 is also 1:2. This design achieves an optimal balance between improved lifespan, maintained color balance, and process feasibility for the blue sub-pixel.

[0059] By setting the area of ​​the third sub-pixel 123 (blue sub-pixel) to 1.8 to 2.5 times the area of ​​the first sub-pixel 121 (red sub-pixel) or the second sub-pixel 122 (green sub-pixel), the light-emitting area of ​​the blue sub-pixel is effectively increased. This reduces the current density of the blue sub-pixel while maintaining the same brightness, slowing down the light decay rate of the blue light-emitting material and significantly improving the color lifespan of the display panel. Simultaneously, the aforementioned area ratio range balances the color gamut and color balance of the display panel, avoiding display quality degradation caused by area ratio imbalance. When the areas of the first sub-pixel 121 and the second sub-pixel 122 are equal, the driving circuit design is simplified, reducing product development costs. The overall effect is optimal when the area ratio is 1:2.

[0060] Please see Figure 3 In other embodiments of this application, within the same pixel unit, the first sub-pixel 121 is a red sub-pixel, the second sub-pixel 122 is a blue sub-pixel, and the third sub-pixel 123 is a green sub-pixel. In this embodiment, within the same pixel unit, the area ratio of the first sub-pixel 121 (red sub-pixel) to the third sub-pixel 123 (green sub-pixel) ranges from 1:1.8 to 1:2.5. For example, the area ratio of the first sub-pixel 121 (red sub-pixel) to the third sub-pixel 123 (green sub-pixel) can be 1:1.9, 1:2, 1:2.1, 1:2.2, 1:2.3, or 1:2.4. The area ratio of the second sub-pixel 122 (blue sub-pixel) to the third sub-pixel 123 (green sub-pixel) ranges from 1:1.8 to 1:2.5. For example, the area ratio of the second sub-pixel 121 (blue sub-pixel) to the third sub-pixel 123 (green sub-pixel) can be 1:1.9, 1:2, 1:2.1, 1:2.2, 1:2.3, or 1:2.4. Preferably, the area ratio of the first sub-pixel 121 to the third sub-pixel 123 is 1:2, and the area ratio of the second sub-pixel 122 to the third sub-pixel 123 is 1:2. In the display field, the green component of white light has the highest brightness proportion, typically about 60% to 70%. The luminous efficiency and lifespan of the green sub-pixel have a decisive impact on the brightness performance and lifespan of the entire display panel. By setting the third sub-pixel 123 as a green sub-pixel and increasing its area to 1.8 to 2.5 times (preferably 2 times) the area of ​​the red or blue sub-pixel, since the green component of white light has the highest brightness proportion, the increase in the area of ​​the green sub-pixel effectively reduces its current density, slows down the light decay rate of the green luminescent material, and significantly improves the brightness lifespan of the display panel.

[0061] Further, see Figure 4In other embodiments of this application, within the same pixel unit, the first sub-pixel 121 includes a first main body 1211 and a plurality of first extensions 1212. The first extensions 1212 extend from the first main body 1211 toward the interior of the pixel unit, and the plurality of first extensions 1212 are arranged parallel to each other. Specifically, in the first pixel unit 111 and the second pixel unit 112, the first main body 1211 extends along the second direction Y, and the plurality of first extensions 1212 extend from the first main body 1211 along the first direction X toward the interior region of the pixel unit, with each first extension 1212 parallel to each other and spaced apart. In the third pixel unit 113 and the fourth pixel unit 14, the first main body 1211 extends along the first direction X, and the plurality of first extensions 1212 extend from the first main body 1211 along the second direction Y toward the interior region of the pixel unit, with each first extension 1212 parallel to each other and spaced apart. Optionally, the number of first extensions 1212 is two, three or more, and the specific number is set according to the desired sub-pixel interleaving density of the pixel unit.

[0062] Within the same pixel unit, the second sub-pixel 122 includes a second main body 1221 and a plurality of second extensions 1222. The second extensions 1222 extend from the second main body 1221 toward the interior of the pixel unit, and the plurality of second extensions 1222 are arranged parallel to each other. Specifically, in the first pixel unit 111 and the second pixel unit 112, the second main body 1221 extends along the second direction Y, and the plurality of second extensions 1222 extend from the second main body 1221 toward the interior region of the pixel unit along the first direction X, with each second extension 1222 parallel to each other and spaced apart. In the third pixel unit 113 and the fourth pixel unit 14, the second main body 1221 extends along the first direction X, and the plurality of second extensions 1222 extend from the second main body 1211 toward the interior region of the pixel unit along the second direction Y, with each second extension 1222 parallel to each other and spaced apart. Optionally, the number of second extensions 1222 is two, three, or more, and the specific number is set according to the desired sub-pixel interleaving density of the pixel unit.

[0063] Within the same pixel unit, the third sub-pixel 123 includes a third main body portion 1231 and a plurality of third extension portions 1232. The third extension portions 1232 extend from the third main body portion 1231 located in diagonally arranged corner regions 13 toward the interior of the pixel unit, and the plurality of third extension portions 1232 are arranged parallel to each other. In this embodiment, the third main body portion 1231 is Z-shaped (or N-shaped), with its two ends respectively located in two diagonally arranged corner regions 13 of the pixel unit. The plurality of third extension portions 1232 extend from the third main body portion 1231 toward the interior of the pixel unit along a first direction X or a second direction Y, and the third extension portions 1232 are parallel to each other and spaced apart.

[0064] It should be noted that the extension direction of the third extension portion 1232 is related to the position of the corner region where the third main body portion 1231 is located. Specifically, when the two ends of the third main body portion 1231 are located in the corner regions 13 of the upper left and lower right corners of the pixel unit, respectively, the third extension portion 1232 extends from the portion of the third main body portion 1231 located in the diagonally arranged corner regions into the pixel unit along the second direction Y. When the two ends of the third main body portion 1231 are located in the corner regions 13 of the upper right and lower left corners of the pixel unit, respectively, the third extension portion 1232 extends from the portion of the third main body portion 1231 located in the diagonally arranged corner regions into the pixel unit along the first direction X.

[0065] Combining the overall arrangement of the four pixel units, in the repeating unit 11, the extensions of the first sub-pixel 121, the second sub-pixel 122 and the third sub-pixel 123 are alternately and staggered in both the first direction X and the second direction Y, thereby forming a uniform distribution of the three-color sub-pixels in both the horizontal and vertical directions.

[0066] In a preferred embodiment, when the first extension 1212, the second extension 1222, and the third extension 1232 are arranged alternately, a preset spacing is provided between adjacent extensions. The preset spacing is set according to the size of the pixel unit and the display resolution requirements to ensure electrical isolation between each sub-pixel 12 and avoid crosstalk.

[0067] By setting each sub-pixel 12 to a "comb-like" structure including a main body and multiple extensions, the effective light-emitting area of ​​each sub-pixel 12 is effectively increased, and the aperture ratio of the pixel unit is improved. Secondly, the extensions of each sub-pixel are arranged overlappingly in the second direction Y, so that an interlocking structure of sub-pixels 12 is formed inside the pixel unit, which further improves the space utilization and is conducive to achieving high-resolution display.

[0068] See Figure 7In other embodiments of this application, the pixel unit is a regular octagon. Within the same pixel unit, the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 each occupy at least two sides of the pixel unit, and the first sub-pixel 121 and the third sub-pixel 123 share at least one side of the pixel unit, as do the second sub-pixel 122 and the third sub-pixel 123. Specifically, taking the first pixel unit 111 as an example, the eight sides of the regular octagon are sequentially labeled as the first to the eighth sides. The first sub-pixel 121 occupies the first, second, and third consecutive sides of the pixel unit; the second sub-pixel 122 occupies the fifth, sixth, and seventh consecutive sides of the pixel unit; and the third sub-pixel 123 occupies the fourth and eighth sides of the pixel unit. The first sub-pixel 121 and the third sub-pixel 123 share the first and third sides of the pixel unit, and the second sub-pixel 122 and the third sub-pixel 123 share the fifth and seventh sides of the pixel unit. Through the above-mentioned shared edge design, close adjacency between sub-pixels 12 is achieved at the boundary of the regular octagonal pixel unit. The third sub-pixel 123 and the pixel unit form two spaced-apart receiving areas 14, with the first sub-pixel 121 disposed in one of the receiving areas 14 and the second sub-pixel 122 disposed in the other receiving area 14.

[0069] In a preferred embodiment, the third sub-pixel 123 surrounds at least a portion of the first sub-pixel 121 and a portion of the second sub-pixel 122 to improve space utilization.

[0070] In a preferred embodiment, the first sub-pixel 121 is hourglass-shaped, and both the first sub-pixel 121 and the second sub-pixel 122 are diamond-shaped. The diamond-shaped sub-pixel has a sharply defined outline, which can fit the corner outline of the regular octagonal pixel unit and the shape of the receiving area 14, which is beneficial to maximizing the area of ​​the sub-pixel 12.

[0071] In some variations of this embodiment, the shapes of the first sub-pixel 121 and the second sub-pixel 122 can also be other shapes, such as rectangles, rhombuses, etc., as long as they are adapted to the shape of the internal space of the regular octagonal pixel unit and the shape of the accommodating area 14.

[0072] This embodiment uses regular octagonal pixel units. Compared to rectangular or regular hexagonal pixel units, regular octagons have more sides and more complex corner structures, providing more space division methods and shape choices for the layout of sub-pixels 12, which is conducive to achieving more flexible pixel design. In addition, each sub-pixel 12 occupies at least two sides of the pixel unit and adjacent sub-pixels share common sides, making the boundaries between sub-pixels 12 more compact, reducing invalid areas, and improving space utilization and aperture ratio.

[0073] like Figure 6As shown, in this embodiment, the pixel unit is a regular hexagon. The second pixel unit 112 is located on one side of the first pixel unit 111 in the second direction Y, and the third pixel unit 113 is located on one side of the first pixel unit 111 in the first direction X. Specifically, among the four pixel units, the first pixel unit 111 is located in the upper left region of the repeating unit 11, the second pixel unit 112 is located below the first pixel unit 111 (i.e., on one side in the second direction Y), the third pixel unit 113 is located to the right of the first pixel unit 111 (i.e., on one side in the first direction X), and the fourth pixel unit 114 is located in the lower right region of the repeating unit 11. The fourth pixel unit 114 is obtained by rotating the third pixel unit 113 along the rotation direction by a first preset angle. The second pixel unit 112 and the third pixel unit 113 are both obtained by rotating the first pixel unit 111 along the rotation direction by a first preset angle. The first preset angle is 180°, and the rotation direction is counterclockwise. That is, the second pixel unit 112 is obtained by rotating the first pixel unit 111 counterclockwise by 180°, the third pixel unit 113 is also obtained by rotating the first pixel unit 111 counterclockwise by 180°, and the fourth pixel unit 114 is obtained by rotating the third pixel unit 113 counterclockwise by 180°.

[0074] Within the same pixel unit, the first sub-pixel 121, the second sub-pixel 122, and the third sub-pixel 123 each occupy at least two sides of the pixel unit. Specifically, taking the first pixel unit 111 as an example, the six sides of the regular hexagon are denoted as the first to the sixth sides. The first sub-pixel 121 occupies the first and second consecutive sides of the pixel unit, the second sub-pixel 122 occupies the fourth and fifth consecutive sides of the pixel unit, and the third sub-pixel 123 occupies at least the third and sixth sides of the pixel unit. The first sub-pixel 121 and the third sub-pixel 123 share the first and second sides of the pixel unit, and the second sub-pixel 122 and the third sub-pixel 123 share the fourth and fifth sides of the pixel unit. Through the above-mentioned shared side design, close adjacency between sub-pixels 12 is achieved at the pixel unit boundary. The third sub-pixel 123 and the pixel unit enclose two spaced-apart receiving areas 14. The first sub-pixel 121 is located in one of the receiving areas 14, and the second sub-pixel 122 is located in the other receiving area 14.

[0075] In a preferred embodiment, the third sub-pixel 123 surrounds at least a portion of the first sub-pixel 121 and a portion of the second sub-pixel 122 to improve space utilization.

[0076] In a preferred embodiment, the third sub-pixel 123 is hourglass-shaped. An hourglass-shaped sub-pixel has a shape that narrows in the middle and widens at both ends, allowing it to fit the corner contours of a regular hexagonal pixel unit. The first sub-pixel 121 and the second sub-pixel 122 are both rhomboid. Rhomboid sub-pixels have a regular geometric shape, facilitating the design and manufacture of the photomask.

[0077] It should be noted that the shapes of the first sub-pixel 121 and the second sub-pixel 122 can also be other shapes, such as triangles, pentagons, etc., as long as they are adapted to the shape of the internal space and the accommodating area 14 of the regular hexagonal pixel unit.

[0078] See Figure 8 In this embodiment, the pixel unit is rectangular. Within the same pixel unit, there are at least two third sub-pixels 123. The first sub-pixel 121 and the second sub-pixel 122 are respectively located in the two diagonally opposite corner regions of the pixel unit, and the third sub-pixel 123 is located in at least the remaining two diagonally opposite corner regions of the pixel unit.

[0079] Specifically, taking the first pixel unit 111 as an example, the rectangle is divided into four corner regions 13: the upper left corner, the upper right corner, the lower left corner, and the lower right corner. The first sub-pixel 121 is located in the upper left corner region 13, and the second sub-pixel 122 is located in the lower right corner region 13. There are three third sub-pixels 123, with two of them located in the upper right corner region 13 and the lower left corner region 13, respectively. The geometric center of the remaining third sub-pixel 123 overlaps with the geometric center of the first pixel unit 111. Thus, the four corner regions are occupied sequentially by the first sub-pixel 121, the two third sub-pixels 123, and the second sub-pixel 122, forming an alternating arrangement along the diagonal direction.

[0080] In this embodiment, the third sub-pixel 123 located in the central region of the pixel unit forms a complementary arrangement with the sub-pixels (including the first sub-pixel 121, the second sub-pixel 122, and the two third sub-pixels 123) located in the four corner regions 13. The third sub-pixel 123 in the central region is adjacent to the sub-pixels 12 in each corner region 13, thereby further improving the space utilization rate inside the pixel unit and increasing the total area of ​​the third sub-pixel 123.

[0081] It should be noted that the number of third sub-pixels 123 can also be two, four, or five, and this application does not impose a specific limitation. Taking the first pixel unit 111 as an example, when the number of third sub-pixels 123 is two, the two third sub-pixels 123 are located in the upper right corner area 13 and the lower left corner area 13, respectively. The geometric center area of ​​the pixel unit does not have a third sub-pixel 123, but is enclosed by the sub-pixels 12 of each corner area 13 to form a central blank area. This central blank area can be used to set other functional devices (such as touch traces or metal traces).

[0082] In a preferred embodiment, each sub-pixel 12 is rectangular or approximately rectangular in shape to accommodate the spatial shape of the corner region 13 of the rectangular pixel unit. The areas of each third sub-pixel 123 can be equal or unequal depending on actual needs.

[0083] like Figure 9 As shown, a second aspect of this application provides a display panel 20, which includes the pixel arrangement structure 10 of any of the embodiments of the first aspect described above. The display panel 20 also includes touch structures (e.g., touch electrodes, touch traces), optical films (e.g., microlenses, polarizers), cover plates, and other structures disposed on the light-emitting side of the display panel 20.

[0084] like Figure 9 As shown, in some optional embodiments, the display panel 20 further includes a substrate 21, a pixel defining layer 22, and a display functional layer 23. The pixel defining layer 22 is disposed on one side of the substrate 21 and includes a pixel defining portion 221 and a pixel opening 222 formed by the pixel defining portion 221. The display functional layer 23 is disposed on the side of the pixel defining layer 22 away from the substrate 21 and is at least partially located within the pixel opening 222. The sub-pixel 12 includes a light-emitting device 231 located in the display functional layer 23.

[0085] Optionally, the light-emitting device 231 corresponds one-to-one with the pixel opening 222, that is, the sub-pixel 12 corresponds one-to-one with the pixel opening 222. In other words, the orthographic projection of each light-emitting device 231 on the substrate 21 and the orthographic projection of each pixel opening 222 on the substrate 21 at least partially overlap.

[0086] Optionally, the display functional layer 23 includes a first electrode layer 232, a light-emitting layer 233, and a second electrode layer 234. The first electrode layer 232 includes a plurality of first electrodes 2321 corresponding one-to-one with the pixel openings 222, and the orthographic projection of the pixel openings 222 on the substrate is located within the orthographic projection range of the first electrodes 2321 on the substrate. That is, the pixel openings 222 expose at least a portion of the first electrodes 2321. The second electrode layer 234 is continuously disposed on the side of the light-emitting layer 233 away from the substrate 21.

[0087] Specifically, the first electrode layer 232 is the anode layer, and the second electrode layer 234 is the cathode layer. The anode is usually made of a transparent conductive oxide (such as indium tin oxide ITO, indium zinc oxide IZO, etc.), and the cathode is usually made of a metallic material (such as silver, aluminum or their alloys).

[0088] There are several other ways to arrange the substrate 21. For example, the substrate 21 may include a substrate and an array substrate disposed on the substrate. The array substrate includes a driving circuit, which may include transistors, storage capacitors, and driving signal lines for connecting various devices. Alternatively, the substrate 21 may be the substrate itself. Or the substrate 21 may include a buffer layer and a support plate on the side facing away from the substrate.

[0089] In some optional embodiments, the light-emitting layer 233 may include a hole injection layer, a hole transport layer, a light-emitting material layer, an electron injection layer, and an electron transport layer.

[0090] Optionally, the display panel 20 may also include an encapsulation layer located on the side of the first electrode layer 232 away from the substrate 21, so as to encapsulate the display functional layer 23 and the first electrode layer 232.

[0091] Optionally, the display panel 20 may also include a touch layer located on the side of the encapsulation layer opposite to the substrate 21 to enable the touch function of the display panel 20.

[0092] Optionally, the display panel 20 may also include a cover plate located on the side of the touch layer opposite to the substrate 21 to achieve encapsulation protection of the display panel 20.

[0093] Since the display panel provided in this application adopts the pixel arrangement structure 10 described in any of the foregoing embodiments, it has at least the same technical effects as the aforementioned pixel arrangement structure 10. That is, it has complete sub-pixels of each color in the horizontal, vertical and diagonal directions, which can effectively improve color shift and color fringing phenomena and improve display quality.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
