[0039] refer to figure 1 , figure 1 A schematic diagram of a pixel array according to an embodiment of the present invention is shown. A pixel array is formed on a non-rectangular substrate 100 . A pixel array includes a plurality of pixels. Specifically, the pixel array includes a plurality of edge pixels 110 located at the edge of the pixel array and a plurality of central pixels surrounded by the plurality of edge pixels 110 ( figure 1 not shown). Each edge pixel 110 has a first boundary 111 facing the boundary of the non-rectangular substrate 100 , and the first boundary 111 is adapted to the shape of the non-rectangular substrate 120 , thereby improving the display effect of the edge pixel. In this embodiment, the non-rectangular substrate 100 has the same shape as each edge pixel 110 , so that each edge pixel 110 has a first boundary 111 adapted to the shape of the non-rectangular substrate 100 . Specifically, the shape of the non-rectangular substrate 100 is circul...

[0043] refer to Figure 2A , Figure 2A A schematic diagram of a pixel array according to an embodiment of the present invention is shown. A pixel array is formed on a non-rectangular substrate 200 . and figure 1 Similarly, the pixel array includes a plurality of edge pixels 210 located at the edge of the pixel array and a plurality of central pixels 230 surrounded by the plurality of edge pixels 210 . In this embodiment, the distance between the first boundary 211 of each edge pixel 210 and the boundary of its adjacent non-rectangular substrate 200 is substantially the same, so that each edge pixel 210 has a first boundary adapted to the shape of the non-rectangular substrate 200 211. Each first boundary 211 adapts to the shape of the non-rectangular substrate 200 to improve the display effect of the pixel array. In this embodiment, the non-rectangular substrate 200 is circular with arc-shaped boundaries. The first border 211 of each edge pixel 210 has the same curvatur...

[0048] refer to Figure 2B , Figure 2B A schematic diagram of a pixel array according to an embodiment of the present invention is shown. Figure 2B The pixel array shown with the Figure 2A similar. its with Figure 2A The difference is that the distance between the first boundary 220' of some edge pixels 210' and the boundary of its adjacent circular substrate 200' is substantially the same, while the first boundary 211A' of another part of edge pixel 210A' and its adjacent circle The borders of the shaped substrate 200' have the same shape. In other words, the first boundary 21 ′ of some edge pixels 210 ′ has the same curvature as its adjacent arc-shaped boundary; 'The curved boundaries of the arcs have different curvatures. Wherein, the same shape in the present invention means that the types of shapes are the same. For example, they could all be arcs, but with different curvatures; they could both be rectangles, but with different aspect ratios; for example, they ...

Abstract

The invention provides a display panel and a pixel array thereof. The pixel array is formed on a non-rectangular substrate and comprises multiple edge pixels. The multiple edge pixels are positioned on the edge of the non-rectangular substrate. Each edge pixel has a first boundary facing the boundary of the non-rectangular substrate, and the first boundary is adapted to the shape of the non-rectangular substrate. The pixel array also comprises multiple central pixels which are surrounded by the multiple edge pixels. The display light effect on the non-rectangular OLED display panel boundary is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a pixel array thereof. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) technology has developed rapidly, and has become a promising technology most likely to replace LCD (Liquid Crystal Display, Liquid Crystal Display). [0003] Compared with OLED display panels with conventional shapes, OLED display panels with irregular shapes, such as non-rectangular shapes, have a novel structure and can be manufactured according to requirements. However, since the boundary of the odd-shaped OLED display panel is not a traditional rectangle consisting of right angles and straight sides, unreasonable design of the display panel boundary will directly affect the display effect of the entire product. [0004] In the fabrication of traditionally shaped OLED display panels, the shape of a pixel is genera...
