[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0030] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This embodiment provides a display panel, which includes multiple display modules 1 and splicing light panels 2. The display modules 1 and splicing light panels 2 are both located on a backlight 3, and light-shielding adhesive 4 is provided on the sides of adjacent display panels. The display module 1 includes an array substrate 11 and a color filter substrate 12; the splicing light panel 2 is located at the connection between the display modules 1; the splicing light panel 2 includes a substrate and sub-pixels of various colors located on the substrate.
[0031] In this substrate, a splicing portion 21 is formed at the edge that connects to the display module 1, and a connecting portion 22 connects the splicing portion 21 to the substrate. For example... Figure 3 As shown, the sub-pixels in the splicing section 21 and the connecting section 22 are arranged in an array, and the array arrangement of the splicing section 21 and the connecting section 22 is the same. That is, in this embodiment, each row of the substrate is provided with sub-pixels of the same color, and each column is provided with sub-pixels of different colors. The row direction in the substrate is the same as the splicing direction of the display module 1. Because each row of the splicing section 21 is provided with sub-pixels of the same color, a problem of poor red and green edge lines will appear at the connection between the display panel and the light panel, affecting the display effect of the entire large screen.
[0032] Please see Figure 4 In some embodiments, the sub-pixels in the splicing section 21 are arranged in an array; each row of the splicing section 21 is provided with sub-pixels of different colors, and each column of the splicing section 21 is provided with sub-pixels of the same color. The row direction of the splicing section 21 is the same as the splicing direction of the splicing section 21, wherein the splicing direction of the splicing section 21 is the edge extension direction connected to the display module 1; each row of the connecting section 22 is provided with sub-pixels of the same color, and each column of the connecting section 22 is provided with sub-pixels of different colors. In this embodiment, the sub-pixels of the splicing section 21 are provided with sub-pixels of different colors along the splicing direction. Compared with the sub-pixels of the same color along the splicing direction, the fusion of multiple colors of light forms uniform light, which can alleviate the color shift problem caused by the formation of poor red and green edges at the connection of sub-pixels of the same color, so as to improve the display effect of the entire display panel.
[0033] In some embodiments, the sub-pixel includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. One red sub-pixel, one green sub-pixel, and one blue sub-pixel constitute one cycle, and are cyclically arranged on each row of the splicing section 21. Specifically, the arrangement order of the three sub-pixels within one cycle can be red sub-pixel, green sub-pixel, and blue sub-pixel; or red sub-pixel, blue sub-pixel, and green sub-pixel; or green sub-pixel, red sub-pixel, and blue sub-pixel; or green sub-pixel, blue sub-pixel, and red sub-pixel; or blue sub-pixel, green sub-pixel, and red sub-pixel.
[0034] In one embodiment, red sub-pixels are arranged in the 1+3Nth column of the splicing section 21, green sub-pixels are arranged in the 2+3Nth column of the splicing section 21, and blue sub-pixels are arranged in the 3+3Nth column of the splicing section 21, where N is a natural number. For example, when N is 0, the splicing section 21 has three rows of pixels, with red sub-pixels arranged in the 1st row, green sub-pixels arranged in the 2nd row, and blue sub-pixels arranged in the 3rd row.
[0035] In one embodiment, the sub-pixels are set in the same direction as the display pixels in display module 1, and the shape of the sub-pixels includes rectangles, each comprising a long side and a short side. In this embodiment, the sub-pixels are set in the same direction as the display pixels in display module 1, which allows the light panel and display module 1 to be better integrated, improving the display effect of the display panel.
[0036] As one embodiment, if the sub-pixel is rectangular, the setting direction of the corresponding sub-pixel includes horizontal, the long side of the sub-pixel is parallel to the row direction of the splicing part 21, and the sub-pixels are kept on the same straight line in the row direction to avoid skewing and ensure the light output effect.
[0037] As one embodiment, if the sub-pixel is rectangular, the sub-pixel is set in a vertical direction, the long side of the sub-pixel is parallel to the column direction of the splicing part 21, and the sub-pixels are kept on the same straight line in the column direction to avoid skewing and ensure the light output effect.
[0038] Please see Figure 5 In another embodiment, the splicing section 21 includes multiple sub-sections 211 along its splicing direction. Similarly, the splicing direction of the splicing section 21, such as the X direction, is the edge extension direction connected to the display module 1. The multiple sub-pixels in the sub-sections 211 are arranged in an array. Each row in the sub-sections 211 is provided with sub-pixels of the same color, and each column in the sub-sections 211 is provided with sub-pixels of different colors. The row direction in the sub-sections 211 intersects the splicing direction of the splicing section 21 at a preset angle α, and the column direction in the sub-sections 211 is perpendicular to the row direction.
[0039] In this embodiment, the arrangement of sub-pixels in the splicing section 21 can be the same as that in the connecting section 22. The difference is that the pixel array is tilted at a preset angle so that sub-pixels of different colors are as close as possible to the edge connected to the display module 1 to mix light. As a result, compared with sub-pixels of the same color set along the splicing direction, the light of multiple colors is fused to form a uniform light, which can alleviate the color shift problem caused by the formation of poor red and green edges at the connection of sub-pixels of the same color, so as to improve the display effect of the entire display panel.
[0040] The sub-pixels include red, green, and blue sub-pixels. One red sub-pixel, one green sub-pixel, and one blue sub-pixel constitute one cycle, which are cyclically arranged in each column of subsection 211. Specifically, the arrangement order of the three sub-pixels within one cycle can be red, green, and blue, or red, blue, and green, or green, red, and blue, or green, blue, and red, or blue, red, and green, or blue, green, and red.
[0041] In this case, the sub-pixels in the same row of adjacent sub-parts 211 have the same color; for example, if the first row of the first sub-part 211 is red sub-pixels, then the first row of the second sub-part 211 is also red sub-pixels, thereby ensuring the uniformity of light output between adjacent sub-parts 211.
[0042] The sub-pixels are rectangular in shape and include a long side and a short side. The long side or short side of the sub-pixel is parallel to the row direction in the sub-section 211. In this embodiment, the pixel array in the sub-section 211 is tilted as a whole, and the long side or short side of the corresponding sub-pixel is kept in a straight line in the row direction to avoid skewing in the row direction, thereby ensuring the light emission effect in each sub-section 211.
