DETAILED DESCRIPTION

[0078] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0079] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0080] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position 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 device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0081] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0082] Please also read Figure 1 , Figure 2 and Figure 3 An embodiment of the present application provides a display panel 100 , which may be an organic light-emitting diode (OLED) display panel 100 or a micro light-emitting diode (Micro Light Emitting Diode, Micro LED / μLED) display panel 100 .

[0083] The display panel 100 includes a display area AA and a non-display area NA, and the non-display area NA surrounds at least a portion of the display area AA.

[0084] The display area AA of the display panel 100 is provided with a plurality of sub-pixels, and the plurality of sub-pixels can be prepared in batches according to the process flow. For example, the plurality of sub-pixels can include a first sub-pixel 1, a second sub-pixel 2, and a third sub-pixel 3, and the first sub-pixel 1, the second sub-pixel 2, and the third sub-pixel 3 can emit light of different colors. For example, the first sub-pixel 1 can emit filtered light, the second sub-pixel 2 can emit red light, and the third sub-pixel 3 can emit blue light.

[0085] The inventors found that in the related art, the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 of the display area are usually arranged along the third direction (eg Figure 2 X direction in the figure) or the fourth direction (such as Figure 2 The sub-pixels are arranged in the Y direction in the display area AA, and when the sub-pixels emit light, a color edge will exist near the edge of the display area AA parallel to the third direction or the fourth direction. It can be understood that the color edge means that only one or two of the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3 are near the edge of the display area AA, and the edge of the other one or the other two sub-pixels is far away from the edge of the display area AA, causing abnormal display of the edge of the display area AA, showing one or two colors of the light emitted by the first sub-pixel 1, the second sub-pixel 2 and the third sub-pixel 3.

[0086] Please also read Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 In order to solve the above technical problems, the embodiment of the present application provides a pixel structure, which can be distributed in a display area (such as display area AA). The pixel structure includes a plurality of repeated pixel units, the pixel unit includes at least one pixel group, the pixel group includes a plurality of sub-pixels and a plurality of partitions 11 separating the plurality of sub-pixels, the partition 11 is located between two adjacent sub-pixels, and the two sub-pixels on both sides of at least one partition 11 are arranged along a first direction (such as Figure 4 The two sub-pixels on both sides of at least one partition 11 are arranged in a spaced relationship along the second direction (eg, Figure 4 The first direction and the second direction are arranged at intervals, and the first direction intersects with the second direction. That is, the spacing directions of the two sub-pixels on both sides of at least some different partitions 11 are different. Optionally, the first direction is perpendicular to the second direction.

[0087] Optionally, a first region 101 is formed between two adjacent partitions 11 ; at least part of the plurality of sub-pixels of the pixel group are distributed in the first region 101 in a one-to-one correspondence.

[0088] Through the above technical solution, the spacing directions of two sub-pixels on both sides of at least some different partitions 11 are different. Compared with the sub-pixels arranged along the same direction, it is beneficial to reduce the distance difference between different sub-pixels and the edge of the pixel group, and then to a certain extent reduce the distance difference between different sub-pixels and the edge of the display area where the pixel structure is located, which can at least alleviate the color edge phenomenon of the display area to a certain extent, which is beneficial to improve the luminous effect of the display panel 100, thereby helping to improve the performance of the display device.

[0089] Therefore, the pixel structure provided in the embodiment of the present application is conducive to improving the performance of the display device.

[0090] In some embodiments, see Fig.12 , the plurality of sub-pixels of the pixel group include a first sub-pixel 1, a second sub-pixel 2 and a third sub-pixel 3. Optionally, the partition 11 may be made of an insulating material.

Optionally, in the same pixel group, the number of partitions 11 is an odd number, and at least two third sub-pixels 3 are located on both sides of the same partition 11.

[0117] It can be understood that in the pixel structure provided in the embodiment of the present application, the number and structural shape of the partitions 11 in the pixel group can be specifically set as needed and can be applicable to more application scenarios.

[0118] Please also read Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9, Fig.10 , Fig.11 and Fig.12 In some embodiments, the pixel unit includes a pixel group. In this way, a pixel group can be repeatedly set as a pixel unit, which is conducive to reducing the difficulty of design.
