Embodiment Construction

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments It is a part of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0066] In the related art, the display substrate includes a plurality of pixel units 10, such as figure 1 As shown, each pixel unit 10 includes a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B. In the preparation process of the display substrate, organic materials are usually evaporated by vacuum evaporation process through dif...

Abstract

According to a display substrate and a display device, by arranging the first pixel units and the second pixel units which are arranged in an array manner, the first color sub-pixels of the first pixel units and the second pixel units can be adjacent, the second color sub-pixels of the first pixel units and the second pixel units can be adjacent, and the third color sub-pixels of the first pixel units and the second pixel units are adjacent. Since the two adjacent sub-pixels with the same color can share one hole in a high-precision metal mask plate for evaporation, the shortest distance between the two adjacent sub-pixels with the same color can be reduced, the position deviation caused by evaporation is reduced, the pixel aperture ratio is improved to the greatest extent, and the preparation of the display device with high resolution and high aperture ratio is facilitated. Besides, as one hole in the high-precision metal mask plate corresponds to the evaporation of the two sub-pixels, the number of the holes in the high-precision metal mask plate can be reduced, and the manufacturing difficulty of the high-precision metal mask plate is reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] Compared with traditional liquid crystal display devices, OLED (Organic Light-Emitting Diode) display devices have the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed, etc., and are one of the hot research fields of display devices at present. , It is more and more widely used in the field of mobile phones and tablet computers. [0003] At present, it is difficult to achieve the best of both worlds in high resolution and high aperture ratio of OLED display devices, that is, it is difficult to ensure high aperture ratio at the same time in the case of high resolution, otherwise defects such as color mixing are prone to occur. Contents of the invention [0004] The disclosure provides a display substrate and a display device t...
