[0031] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] ​​​In the description of the present application, it needs to be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can be explicitly or implicitly included one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0033] The current seamless splicing scheme is composed of display area A to display area G. Among them, display area A to display area D are traditional liquid crystal display screens, which have the advantages of low cost, and the disadvantages of standard size, poor flexibility, and frame. Display area E to G is a mini-LED direct display scheme, which has the advantages of adjustable size and proportion, and no frame; the disadvantage is that the unit area cost is higher. The use of mini-LED direct display splices two adjacent liquid crystal display screens, and then realizes the splicing of two display technologies, so as to take the advantages of each other and realize a low-cost seamless splicing scheme.

[0034] However, in actual application, such as Figure 1 As described, Figure 1 is a schematic diagram of the structure of the current display panel. The mini-LED direct display includes an edge area 10 and a center area, wherein the upper edge and the lower edge of the edge area 10, because of the uniformity of the pixel arrangement, cause the observer to perceive that there is a red line on the upper edge of the mini-LED direct display, and there is a blue line on the lower edge.

[0035] Specifically, because the mini-LED display unit F in the traditional scheme, the pixel arrangement is R (Red), G (Green), and B (Blue) three sub-pixels, which are uniformly arranged, and the three sub-pixels constitute a pixel. Because the entire R sub-pixel on the upper edge has no other sub-pixels to mix color with the R sub-pixel on the outside, the observer will perceive a red line on the upper edge of the display area when watching; similarly, because the B sub-pixel on the lower edge has no other pixels to mix color on the outside, the observer will perceive a blue line on the lower edge of the display area.

[0036] Therefore, in order to solve the above problems, the application provides a display panel and a spliced display device. The application will be further described below in combination with the drawings and embodiments.

[0037] Please refer to Figure 2 , Figure 2 The first structure schematic diagram of the spliced display device provided by the embodiment of the application is shown. The embodiment of the application also provides a spliced display device, which comprises a display panel 100, a first display panel 200 and a second display panel 300. A plurality of unit pixels are arranged on the first display panel 200, a plurality of unit pixels are arranged on the second display panel 300, and the second display panel 300 is adjacent to the first display panel 200. The display panel 100 is arranged between the first display panel 200 and the second display panel 300 to splice the first display panel 200 and the second display panel 300. The edge area 10 on both sides of the display panel 100 is arranged on one side close to the center area 20 of the first display panel 200 and one side close to the center area 20 of the second display panel 300, respectively. By arranging the display panel 100 between the first display panel 200 and the second display panel 300, the splicing places between the first display panel 200 and the display panel 100 and between the second display panel 300 and the display panel 100 can be made more gentle, and the side monochrome phenomenon can be avoided. In turn, the first display panel 200, the second display panel 300 and the display panel 100 can be seamlessly spliced.

[0038] Please continue to refer to Figure 3 , Figure 3 The second structure schematic diagram of the spliced display device provided by the embodiment of the application is shown. The spliced display device can comprise a plurality of display panels 100, a plurality of first display panels 200 and a plurality of second display panels 300. One display panel 100 is arranged between adjacent first display panel 200 and second display panel 300, and the edge area of the display panel 100 is arranged close to the two sides of the first display panel 200 and the second display panel 300, respectively. By combining and splicing the plurality of display panels 100, the plurality of first display panels 200 and the plurality of second display panels 300, the spliced display device can realize a larger size display effect.

[0039] It should be noted that in some embodiments, the first display panel 200 and the second display panel 300 can be conventional liquid crystal display screens, which are low in cost. The display panel 100 can be a Micro LED direct display or a flexible OLED. Specifically, it can be set according to actual conditions.

[0040] Please refer to Figure 4 , Figure 4A first structural schematic diagram of a display panel is provided in the embodiments of the present application. The embodiments of the present application provide a display panel 100, which comprises a center area 20 and an edge area 10. The center area 20 is provided with a plurality of first pixel units 40 arranged in an array. The sub-pixels of each first pixel unit 40 are arranged along a first direction. The edge area 10 is arranged at two ends of the center area 20. The edge area 10 is provided with a plurality of second pixel units 30 arranged along a second direction. The sub-pixels of the second pixel unit 30 are arranged along the second direction. The polarities of two adjacent second pixel units 30 are opposite. The first direction and the second direction are perpendicular. By arranging the sub-pixels in the second pixel unit 30 along the second direction, the light emitted by the plurality of sub-pixels towards the edge area can be mixed, so that the light emitted by the upper and lower edges of the display panel 100 is mixed, and the single-color light emission at the edges can be avoided. By arranging the sub-pixels in the first pixel unit 40 along the first direction, the light emitted by the plurality of sub-pixels towards the edge area can be mixed, so that the light emitted by the left and right edges of the display panel 100 is mixed. Therefore, by arranging the sub-pixels in each first pixel unit 40 perpendicularly to the sub-pixels in each second pixel unit 30, the uniform light emission of the edge area 10 at the upper, lower, left and right edges of the display panel 100 can be ensured, thereby solving the problem of visual brightness deviation. In addition, the polarities of the two adjacent second pixel units 30 are opposite, which can avoid the deviation after the packaging process, thereby further reducing the visual brightness deviation.

[0041] In some embodiments, the second pixel unit 30 comprises a first sub-pixel unit 310 and a second sub-pixel unit 320 arranged in a cross manner. The arrangement order of the sub-pixels in the first sub-pixel unit 310 is opposite to that of the sub-pixels in the second sub-pixel unit 320. For example, the sub-pixels in the first pixel unit 40 comprise a red sub-pixel, a green sub-pixel and a blue sub-pixel arranged in sequence. The sub-pixels in the first sub-pixel unit 310 comprise a red sub-pixel, a green sub-pixel and a blue sub-pixel arranged in sequence. The sub-pixels in the second sub-pixel unit 320 comprise a blue sub-pixel, a green sub-pixel and a red sub-pixel arranged in sequence.

[0042] It can be understood that the number of sub-pixels in each pixel unit and the colors of the sub-pixels are not limited to the above. For example, the sub-pixels in the first sub-pixel unit 310 and the sub-pixels in the second sub-pixel unit 320 are not limited to the red sub-pixel, the green sub-pixel and the blue sub-pixel, but can be four sub-pixels, such as a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. They can also be a red sub-pixel, a green sub-pixel, a blue sub-pixel and a yellow sub-pixel, etc. The specific setting needs to be made according to the actual situation, which is not limited here.

[0043] That is, the first sub-pixel unit 310 is rotated by -90° relative to the first pixel unit 40, and the second sub-pixel unit 320 is rotated by +90° relative to the first pixel unit 40. By rotating the first sub-pixel unit 310 and the second sub-pixel unit 320 by -90° and +90°, respectively, relative to the first pixel unit 40, the light emitted by the edge region 10 can be mixed, rather than being monochromatic, which can solve the problem of uneven edge light emission and balance the difference in left and right viewing angles. Moreover, the first sub-pixel unit 310 and the second sub-pixel unit 320 are only rotated relative to the position of the first pixel unit 40 when attached, and the structure is not changed, which can make the processing process simpler. In addition, by arranging the second pixel unit 30 as the first sub-pixel unit 310 and the second sub-pixel unit 320 arranged in a cross shape, the polarity of the first sub-pixel unit 310 and the second sub-pixel unit 320 facing the same side of the adjacent first sub-pixel unit 310 and the second sub-pixel unit 320 can be opposite, which can alleviate the problem of deviation in left and right viewing angles.

[0044] It can be understood that the underlying circuit contacts must be designed according to the arrangement of the pixel units described above when the layout is designed, so that the corresponding pixel units can be used.

[0045] Please continue to refer to Figure 5 , Figure 5 for Figure 1 the second structure of the display panel is shown. In some embodiments, the display panel 100 further comprises a transition region 60, the transition region 60 is arranged between the center region 20 and the edge region 10, and a plurality of third pixel units and a plurality of fourth pixel units 520 are arranged on the transition region 60. The plurality of sub-pixels of each third pixel unit are arranged along the first direction, and the plurality of sub-pixels of each fourth pixel unit 520 are arranged along the second direction. That is, the pixel arrangement is also rearranged in the next row at the beginning and end. By arranging the transition region 60 between the center region 20 and the edge region 10, the color difference caused by the edge can be further reduced, the color transition of the edge is more moderate, and the viewing angle difference caused by the pure color picture is balanced.

[0046] In some embodiments, the order of the plurality of sub-pixels of any two adjacent fourth pixel units 520 is opposite, and in some embodiments, the order of the plurality of sub-pixels of any two adjacent third pixel units is same. In the embodiments of the present application, the fourth pixel unit 520 includes a third sub-pixel unit 530 and a fourth sub-pixel unit 510, wherein the third sub-pixel unit 530 corresponds to the first sub-pixel unit 310 described above, the fourth sub-pixel unit 510 corresponds to the second sub-pixel unit 320 described above, and the third pixel unit corresponds to the first pixel unit 40 described above. The specific arrangement of the plurality of sub-pixels in the third sub-pixel unit 530 and the fourth sub-pixel unit 510 will not be described here, and the details can be seen from the above description. The specific arrangement of the third pixel unit will not be described here, and the details can be seen from the above description.

[0047] For example, in some embodiments, one fourth pixel unit 520 is arranged between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510. By arranging one fourth pixel unit 520 between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510, the color transition of the edge can be more moderate.

[0048] The first sub-pixel unit 310 and the fourth pixel unit 520 share a cathode line, and the second sub-pixel unit 320 and the third pixel unit share an anode line. Specifically, in the first column, the first sub-pixel unit 310 located in the edge area 10, the fourth sub-pixel unit 510 located in the transition area 60, and the first pixel unit 40 located in the center area 20 share a cathode line. In the second column, the second sub-pixel unit 320 located in the edge area 10, the fourth pixel unit 520 located in the transition area 60, and the first pixel unit 40 located in the center area 20 share an anode line. In the third column, the first sub-pixel unit 310 located in the edge area 10, the third sub-pixel unit 530 located in the transition area 60, and the first pixel unit 40 located in the center area 20 share a cathode line. In the fourth column, the second sub-pixel unit 320 located in the edge area 10, the fourth pixel unit 520 located in the transition area 60, and the first pixel unit 40 located in the center area 20 share an anode line. In this way, along the first direction, the first column, the second column, the third column, and the fourth column are arranged in this order in a cycle, so that the color transition of the edge is more moderate, and the color is not abrupt.

[0049] In other embodiments, in order to make the color transition of the edge more moderate, while ensuring the convenience of the process, a plurality of fourth pixel units 520 are arranged between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510, and the number of fourth pixel units 520 arranged between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510 is same. By increasing the number of fourth pixel units 520 arranged between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510, the color between the edge area 10 and the center area 20 can be made more moderate.

[0050] In some other embodiments, in order to further make the color transition of the edge more moderate, the number of fourth pixel units 520 between the adjacent third sub-pixel units 530 and fourth sub-pixel units 510 gradually increases in the direction from the two sides to the center of the transition area 60. By gradually increasing the number of fourth pixel units 520, the red sub-pixel, green sub-pixel and blue sub-pixel in the adjacent pixels can be better mixed, and the color transition of the edge can be more moderate, so that the light emitted by the edge area 10 of the display panel 100 is uniform, the problem of deviation of the left and right side viewing angles is alleviated, and the problem of visual brightness deviation is solved.

[0051] In some embodiments, the edge area includes a first row of pixels and a last row of pixels, the first row of pixels and the last row of pixels are arranged on both sides of the center area, the transition area includes a second row of pixels and a second-to-last row of pixels, the second row of pixels is arranged between the center area and the first row of pixels, and the second-to-last row of pixels is arranged between the center area and the last row of pixels.

[0052] Please continue to refer to Figure 6 , Figure 6 for Figure 5 the third structure diagram of the display panel is shown. In some other embodiments, the second pixel unit 30 includes a first sub-pixel unit 310 and a second sub-pixel unit 320 arranged in cross. The arrangement order of the sub-pixels in the first sub-pixel unit 310 is the same as the arrangement order of the sub-pixels in the second sub-pixel unit 320. For example, the sub-pixels in the first pixel unit 40 include red sub-pixels, green sub-pixels and blue sub-pixels arranged in sequence, the sub-pixels in the first sub-pixel unit 310 include red sub-pixels, green sub-pixels and blue sub-pixels arranged in sequence, and the sub-pixels in the second sub-pixel unit 320 include red sub-pixels, green sub-pixels and blue sub-pixels arranged in sequence, but the polarity of the second sub-pixel unit 320 is opposite to the polarity of the first sub-pixel unit 310 and the polarity of the first pixel unit 40.

[0053] That is, the first sub-pixel unit 310 is rotated by -90° relative to the first pixel unit 40. By arranging the first sub-pixel unit 310 and the second sub-pixel unit 320 as described above, the color difference of the edge can be reduced, the light emitted by the edge area 10 can be mixed, not single color, and the problem of uneven edge light emission can be solved. In addition, by arranging the second pixel unit 30 as the first sub-pixel unit 310 and the second sub-pixel unit 320 arranged in cross, the polarity of the first sub-pixel unit 310 and the second sub-pixel unit 320 facing the same side is opposite, which can alleviate the problem of deviation of the left and right side viewing angles.

[0054] Please continue to refer toFigure 7 , Figure 7 for Figure 5 The diagram shows a fourth structural schematic of the display panel. In some embodiments, the transition area 60 is provided with a... Figure 4 The aforementioned third and fourth pixel units 520, i.e., the next row after the first and last pixels, also have their pixels rearranged. By setting a transition area 60 between the center area 20 and the edge area 10, the color difference generated at the edge can be further reduced, making the color transition at the edge smoother, and balancing the viewing angle differences caused by solid color images.

[0055] For example, in some embodiments, a fourth pixel unit 520 is spaced between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510. By spacing them by a fourth pixel unit 520, the color transition at the edges can be made smoother. Specifically, in the first column, the first sub-pixel unit 310 located in the edge region 10, the third sub-pixel unit 530 located in the transition region 60 after rotating positive 90°, and the first pixel unit 40 located in the center region 20 share a cathode line. In the second column, the second sub-pixel unit 320 located in the edge region 10, the fourth pixel unit 520 located in the transition region 60, and the first pixel unit 40 located in the center region 20 share an anode line. In the third column, the first sub-pixel unit 310 located in the edge region 10, the fourth sub-pixel unit 510 located in the transition region 60 after rotating negative 90°, and the first pixel unit 40 located in the center region 20 share a cathode line. In the fourth column, the second sub-pixel unit 320 located in the edge region 10, the fourth pixel unit 520 located in the transition region 60, and the first pixel unit 40 located in the center region 20 share the same anode line. Thus, along the first direction, the first, second, third, and fourth columns are arranged in this cyclical order to make the color transition at the edges smoother and avoid abrupt color changes.

[0056] It is understandable that in the transition area 60, the number of fourth pixel units 520 between each adjacent third sub-pixel unit 530 and fourth sub-pixel unit 510 can be designed according to the above method, as can be seen in the above situation, and will not be elaborated here.

[0057] It should be noted that, in the manufacturing process of the aforementioned display panel 100, although the chip packaging method has little impact on the viewing angle difference, in order to avoid deviations after the packaging process, the positive and negative electrodes will be alternately reversed when attaching the pixel units.

[0058] The display panel and the spliced display device provided by the embodiments of the present application are described in detail. The principles and implementation manners of the present application are described by applying specific examples, and the above description of the embodiments is only used to help understand the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed, and the above description of the specification should not be understood as the limitation of the present application.
