[0042] Reference Figure 1~2 As shown, an embodiment of the present application provides a pixel arrangement structure, wherein a repeating unit includes a first sub-pixel 11, a second sub-pixel 12 and a third sub-pixel 13; the second sub-pixel 12 and the third sub-pixel 13 are centrally symmetrically arranged.

[0043] In some embodiments, the repeating unit includes a first sub-pixel 11 , a second sub-pixel 12 , and a third sub-pixel 13 .

[0044] In the above pixel arrangement structure, the repeating unit 10 includes a second sub-pixel 12 and a third sub-pixel 13 of the same shape and size, and a first sub-pixel 11. In the pixel arrangement structure, there are more pixel units per unit area, which can achieve higher resolution.

[0045] It is understandable that the array structure formed by the multiple repeating units 10 is a translational arrangement relationship between the repeating units 10. It is understandable that in the display panel, due to differences in the preparation process, equipment, etc., there may be gaps within the acceptable range in the art between the sub-pixels of the present application, which should be understood to be within the protection scope of the present application. At the same time, due to differences in the preparation process, equipment, etc., there may be gaps within the acceptable range in the art between the repeating units 10 in the present application, which should be understood to be within the protection scope of the present application.

[0046] In some embodiments, the second sub-pixel 12 and the third sub-pixel 13 have the same shape and size.

[0047] For example, refer to Figure 2 As shown, the midpoint of the line connecting the center of the second sub-pixel 12 and the center of the third sub-pixel 13 is the symmetry center of the second sub-pixel 12 and the third sub-pixel 13. The center-symmetric arrangement of the second sub-pixel 12 and the third sub-pixel 13 means that the second sub-pixel 12 can overlap with the third sub-pixel 13 after rotating 180° around the symmetry center.

[0048] In some embodiments, in the pixel arrangement structure, a plurality of second sub-pixels 12 and a plurality of third sub-pixels 13 alternately surround a first sub-pixel 11. In the pixel arrangement structure, there are more pixel units per unit area, which can achieve a higher resolution.

[0049] In some embodiments, in the pixel arrangement structure, three second sub-pixels 12 and three third sub-pixels 13 alternately surround one first sub-pixel 11. In the pixel arrangement structure, there are more pixel units per unit area, which can achieve a higher resolution.

[0050] In some embodiments, in the pixel arrangement structure, three first sub-pixels 11 and three third sub-pixels 13 alternately surround one second sub-pixel 12 .

[0051] In some embodiments, in the pixel arrangement structure, three first sub-pixels 11 and three second sub-pixels 12 alternately surround one third sub-pixel 13 .

[0052] In some embodiments, the first sub-pixel 11 is a polygon.

[0053] In some embodiments, the second sub-pixel 12 is a polygon.

[0054] In some embodiments, the third sub-pixel 13 is a polygon.

[0055] In some embodiments, the second sub-pixel 12 and the third sub-pixel 13 are staggered in the column direction. The first sub-pixel 11 is a polygon, and the maximum side length of the first sub-pixel 11 is less than or equal to the staggered distance between the second sub-pixel 12 and the third sub-pixel 13. This arrangement method can arrange the first sub-pixel 11 at a blank position formed by the staggered arrangement of the second sub-pixel 12 and the third sub-pixel 13, and can obtain a larger aperture ratio.

[0056] Reference Figure 3~4 As shown, in some embodiments, the second sub-pixel 12 and the third sub-pixel 13 are isosceles triangles, and the base of the second sub-pixel 12 and the base of the third sub-pixel 13 are arranged opposite to each other; the first sub-pixel 11 is an equilateral hexagon, and at least four internal angles of the first sub-pixel 11 are complementary to the base angles of the isosceles triangle; in a single repeating unit 10, one side of the first sub-pixel 11 and the base of the second sub-pixel 12 are arranged opposite to each other, and the other side of the first sub-pixel 11 and the waist of the third sub-pixel 13 are arranged opposite to each other.

[0057] It should be noted that two sides being arranged relative to each other means that the two sides are parallel, partially overlapped, or completely overlapped. Exemplarily, when the second sub-pixel 12 and the third sub-pixel 13 are arranged in a staggered manner, the bottom side of the second sub-pixel 12 and the bottom side of the third sub-pixel 13 being arranged relative to each other means that the bottom side of the second sub-pixel 12 and the bottom side of the third sub-pixel 13 are partially overlapped or parallel. Two sides being arranged side by side means that the two sides are partially overlapped or completely overlapped.

[0058] It can be understood that when the first sub-pixel 11 is an equilateral hexagon and at least four internal angles are complementary to the base angles of the isosceles triangle, the first sub-pixel 11 is an equilateral hexagon with the perpendicular bisector of one side as the axis. At this time, one side of the first sub-pixel 11 is relatively arranged with the bottom side of the second sub-pixel 12, and the other side of the first sub-pixel 11 is relatively arranged with the waist of the third sub-pixel 13, so that the other side of the first sub-pixel 11 is located on the extension line of the waist of the second sub-pixel 12, and the angle between the first sub-pixel 11 and the third sub-pixel 13 is equal to the vertex angle of the second sub-pixel 12. The repeating unit 10 of this structure can achieve a higher aperture ratio. Further, when the above-mentioned relatively arranged sides overlap, the repeating unit 10 of this structure can achieve full coverage in the space. Thus, when the space is fully covered, each first sub-pixel 11 is adjacent to three second sub-pixels 12 and three third sub-pixels 13, and there are more pixel units per unit area, which can achieve a higher resolution.

[0059] In addition, due to differences in preparation processes, equipment, etc., the shape of each sub-pixel in the present application may not be a strict isosceles triangle or equilateral hexagon, and there may be errors between the side lengths of each sub-pixel within an acceptable range in the art, which should be understood to be within the scope of protection of the present application.

[0060] In some embodiments, the side length of the equilateral hexagon is a, the waist length of the isosceles triangle is b, and in a single repeating unit 10, the distance between the center of the first sub-pixel 11 and the center of the second sub-pixel 12 is c, where: <c≤ Within the range of the distance between the center of the first sub-pixel 11 and the center of the second sub-pixel 12, the size of the gap between the sub-pixels in the repeating unit 10 is relatively appropriate, and the repeating unit can achieve a higher aperture ratio in the space.

[0061] In some embodiments, the first sub-pixel 11 , the second sub-pixel 12 , and the third sub-pixel 13 emit different colors of light.

[0062] In some embodiments, each first sub-pixel 11 is disposed adjacent to three second sub-pixels 12 and three third sub-pixels 13 in an edge-to-edge manner. Figure 3 As shown, when each first sub-pixel 11 is adjacent to three second sub-pixels 12 and three third sub-pixels 13 in an edge-to-edge arrangement, a plurality of repeating units 10 are in contact with each other and form a full coverage in the space. At this time, each first sub-pixel 11 is adjacent to three second sub-pixels 12 and three third sub-pixels 13, each second sub-pixel 12 is adjacent to three first sub-pixels 11 and three third sub-pixels 13, and each third sub-pixel 13 is adjacent to three first sub-pixels 11 and three second sub-pixels 12. That is, in this pixel arrangement structure, while achieving full coverage in the space, it is also possible to achieve more pixel units per unit area, and a higher resolution can be achieved.

[0063] Reference Figures 5 and 6 As shown, in some embodiments, the second sub-pixel 12 and the third sub-pixel 13 are in the same regular triangle shape, and the first sub-pixel 11 is in the regular hexagon shape.

[0064] In some embodiments, the distance between the bottom edge of the second sub-pixel 12 and the bottom edge of the third sub-pixel 13 is equal to the side length of the first sub-pixel 11 .

[0065] For example, refer to Figure 3 As shown, Figure 3 Here, a is the distance between the bottom edges of the second sub-pixel 12 and the bottom edges of the third sub-pixel 13 .

[0066] In some embodiments, the side length of the equilateral triangle is b, a<b≤5a. Within the side length range of the equilateral triangle, the area of ​​the equilateral triangle is greater than the area of ​​the regular hexagon. At the same time, the area of ​​the regular hexagon is within a suitable range, and the color rendering effect of the pixel arrangement structure is better. Optionally, the side length b of the equilateral triangle is 2.5a, 2.6a, 2.7a, 2.8a, 2.9a, 3a, 3.1a, 3.2a, 3.3a, 3.4a, 3.5a, 3.6a, 3.7a, 3.8a, 3.9a, 4a, 4.1a, 4.2a, 4.3a, 4.4a, 4.5a, 4.6a, 4.7a, 4.8a, 4.9a or 5a. Alternatively, the side length b of the equilateral triangle may also be within the range between any two of the above side lengths. For example, referring to Figure 3 As shown, Figure 3 a is the side length of the regular hexagon. Figure 3 Here b is the side length of the equilateral triangle.

[0067] In some embodiments, the first sub-pixel 11 is a first sub-pixel 11 with rounded corners.

[0068] In some embodiments, the second sub-pixel 12 is a second sub-pixel 12 with rounded corners.

[0069] In some embodiments, the third sub-pixel 13 is the second sub-pixel 12 with rounded corners.

[0070] In some embodiments, an auxiliary electrode is disposed in a blank area formed by rounded corners between adjacent sub-pixels.

[0071] In some embodiments, the number of auxiliary electrodes is 1, 2 or 3.

[0072] In some embodiments, the first sub-pixel 11 is a green pixel. When the area of ​​the first sub-pixel 11 is smaller than that of the second sub-pixel 12 and the third sub-pixel 13, for OLED or QLED, the green pixel has the highest luminous efficiency and luminous life compared with the blue pixel and the red pixel. Setting the first sub-pixel 11 as a green OLED pixel or a green QLED pixel can make the pixel with lower luminous efficiency and luminous life have a larger area, that is, it can achieve a luminous effect of blue pixels and red pixels with equal brightness to green pixels through a smaller driving current, thereby improving the overall luminous life of the light-emitting device.

[0073] In some embodiments, the second sub-pixel 12 is a blue OLED pixel, a blue QLED pixel, a red OLED pixel, or a red QLED pixel.

[0074] In some embodiments, the third sub-pixel 13 is a blue OLED pixel, a blue QLED pixel, a red OLED pixel, or a red QLED pixel.

[0075] Reference Figure 7 As shown, in some embodiments, the second sub-pixel 12 includes a first sub-pixel 121 and a second sub-pixel 122, and the light-emitting wavelengths of the first sub-pixel 121 and the second sub-pixel 122 are different. Dividing the second sub-pixel 12 into the first sub-pixel 121 and the second sub-pixel 122 with different light-emitting wavelengths can further achieve a light-emitting effect of the second sub-pixel 12 having the same brightness as the first sub-pixel 11 through a smaller driving current, thereby improving the overall light-emitting life of the light-emitting device.

[0076] In some embodiments, the difference between the peak wavelength of light emission of the second sub-pixel 122 and the peak wavelength of light emission of the first sub-pixel 121 is 0-100 nm. Optionally, the difference between the peak wavelength of light emission of the second sub-pixel 122 and the peak wavelength of light emission of the first sub-pixel 121 is 1 nm, 5 nm, 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm or 100 nm. Alternatively, the difference between the peak wavelength of light emission of the second sub-pixel 122 and the peak wavelength of light emission of the first sub-pixel 121 may also be within the range between any two of the above differences.

[0077] In some embodiments, the peak emission wavelength of the first sub-pixel 121 is 400nm~460nm. For OLED or QLED, blue pixels have the lowest luminous efficiency and luminous life compared to green pixels and red pixels. Dividing the second sub-pixel 12 into a first sub-pixel 121 and a second sub-pixel 122 with different luminous peak wavelengths can further achieve a luminous effect of the second sub-pixel 12 having the same brightness as the green first sub-pixel 11 through a smaller driving current, thereby improving the overall luminous life of the light-emitting device. Optionally, the peak emission wavelength of the first sub-pixel 121 is 400nm, 405nm, 410nm, 415nm, 420nm, 425nm, 430nm, 435nm, 440nm, 445nm, 450nm, 455nm or 460nm. Or the peak emission wavelength of the first sub-pixel 121 can also be within the range between any two of the above-mentioned peak emission wavelengths.

[0078] In some embodiments, the area of ​​the first sub-pixel 121 is 10% to 30% of the area of ​​the second sub-pixel 12. Within the range of the percentage of the area of ​​the first sub-pixel 121 to the area of ​​the second sub-pixel 12, it is possible to further achieve a light-emitting effect of the second sub-pixel 12 having the same brightness as the green first sub-pixel 11 through a smaller driving current, thereby improving the overall light-emitting life of the light-emitting device. Optionally, the area of ​​the first sub-pixel 121 is 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29% or 30% of the area of ​​the second sub-pixel 12. Alternatively, the percentage of the area of ​​the first sub-pixel 121 to the area of ​​the second sub-pixel 12 can also be within the range between any two of the above percentages.

[0079] In some embodiments, the peak wavelength of the light emission of the second sub-pixel 122 is 460nm-500nm. Optionally, the peak wavelength of the light emission of the second sub-pixel 122 is 460nm, 462nm, 464nm, 466nm, 468nm, 470nm, 472nm, 474nm, 476nm, 478nm, 480nm, 482nm, 484nm, 486nm, 488nm, 490nm, 492nm, 494nm, 496nm, 498nm or 500nm. Alternatively, the light emission wavelength of the second sub-pixel 122 may also be within the range between any two of the above light emission wavelengths.

[0080] In some embodiments, the area of ​​the second sub-pixel 122 is 70% to 90% of the area of ​​the second sub-pixel 12. Within the range of the percentage of the area of ​​the second sub-pixel 122 to the area of ​​the second sub-pixel 12, it is possible to further achieve a light-emitting effect of the second sub-pixel 12 having the same brightness as the green first sub-pixel 11 through a smaller driving current, thereby improving the overall light-emitting life of the light-emitting device. Optionally, the area of ​​the second sub-pixel 122 is 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89% or 90% of the area of ​​the second sub-pixel 12. Alternatively, the percentage of the area of ​​the second sub-pixel 122 to the area of ​​the second sub-pixel 12 can also be within the range between any two of the above percentages.

[0081] In some embodiments, the first sub-pixel 11 is a blue LED pixel. When the area of ​​the first sub-pixel 11 is smaller than that of the second sub-pixel 12 and the third sub-pixel 13, for LED, the blue pixel has the highest luminous efficiency and luminous life compared to the green pixel and the red pixel. Setting the first sub-pixel 11 as a blue LED pixel can make the pixel with lower luminous efficiency and luminous life have a larger area, that is, it can achieve a luminous effect of equal brightness of the green pixel and the red pixel with a smaller driving current, thereby improving the overall luminous life of the light-emitting device. It can be understood that the above-mentioned LED includes micro LED and mini LED.

[0082] In some embodiments, the second sub-pixel 12 is a green LED pixel or a red LED pixel.

[0083] In some embodiments, the third sub-pixel 13 is a green LED pixel or a red LED pixel.

[0084] In some embodiments, the second sub-pixel 12 includes a first sub-pixel 121 and a second sub-pixel 122, and the light emission wavelengths of the first sub-pixel 121 and the second sub-pixel 122 are different. When the first sub-pixel 11 is a blue LED pixel, the second sub-pixel 12 is divided into the first sub-pixel 121 and the second sub-pixel 122 with different light emission wavelengths, which can further achieve a light emission effect of the second sub-pixel 12 having the same brightness as the blue first sub-pixel 11 through a smaller driving current, thereby improving the overall light emission life of the light-emitting device.

[0085] In some embodiments, the peak emission wavelength of the first sub-pixel 121 is 600nm~620nm. For LEDs, red pixels have the lowest luminous efficiency and luminous life compared to green pixels and blue pixels. Dividing the second sub-pixel 12 into a first sub-pixel 121 and a second sub-pixel 122 with different luminous wavelengths can further achieve a luminous effect of the second sub-pixel 12 having the same brightness as the blue first sub-pixel 11 through a smaller driving current, thereby improving the overall luminous life of the light-emitting device. Optionally, the peak emission wavelength of the first sub-pixel 121 is 600nm, 601nm, 602nm, 603nm, 604nm, 605nm, 606nm, 607nm, 608nm, 609nm, 610nm, 611nm, 612nm, 613nm, 614nm, 615nm, 616nm, 617nm, 618nm, 619nm or 620nm. Alternatively, the luminous wavelength of the first sub-pixel 121 may also be within the range between any two of the above luminous wavelengths.

[0086] In some embodiments, the area of ​​the first sub-pixel 121 is 10% to 30% of the area of ​​the second sub-pixel 12. Within the range of the percentage of the area of ​​the first sub-pixel 121 to the area of ​​the second sub-pixel 12, it is possible to further achieve a light-emitting effect of the second sub-pixel 12 having the same brightness as the blue first sub-pixel 11 through a smaller driving current, thereby improving the overall light-emitting life of the light-emitting device. Optionally, the area of ​​the first sub-pixel 121 is 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29% or 30% of the area of ​​the second sub-pixel 12.
