Pixel arrangement structure, light-emitting device and display panel

Abstract

The invention relates to a pixel arrangement structure, a light-emitting device and a display panel. The pixel arrangement structure comprises a plurality of first sub-pixel groups, a plurality of second sub-pixel groups and a plurality of third sub-pixel groups, the first sub-pixel groups, the second sub-pixel groups and the third sub-pixel groups are different in light-emitting color, and each sub-pixel group is composed of a plurality of sub-pixels with the same light-emitting color. The first sub-pixel group and the second sub-pixel group are cross-shaped; the first sub-pixel groups and the second sub-pixel groups which are in a cross shape are alternately arranged in the row direction and the column direction, and every two first sub-pixel groups and every two second sub-pixel groupsare arranged around one third sub-pixel group to form an array structure. According to the pixel arrangement structure, the resolution of the display panel can be improved on the basis of not increasing the preparation difficulty.

Description

technical field [0001] The present invention relates to the technical field of electronic display, in particular to a pixel arrangement structure, a light-emitting device and a display panel. Background technique [0002] At present, OLED displays have the advantages of self-illumination, fast response, wide viewing angle, high brightness, and thinness, and become the mainstream of future displays. The ways to achieve full-color display include vapor deposition of organic light-emitting materials and solution processing. Among them, vapor deposition of organic light-emitting materials is currently the most widely used way to achieve full-color display. It mainly uses precise metal shadow mask and pixel alignment technology to prepare red, green, and blue light-emitting layers by vapor deposition. Solution processing to produce displays, due to its advantages of low cost, high productivity, and easy realization of large sizes, is an important direction for the development of...

AI Technical Summary

Problems solved by technology

However, with the continuous development of display technology, the resolution of the display panel is getting higher and higher, and the evaporation method is limited by the accuracy of the shadow mask pattern size, which makes the resolution of the display prepared by this method limited.

To achieve high-resolution products, it is usually necessary to design the pixels to be relatively small, which imposes strict requirements on printing equipment, and current printing equipment cannot meet high-pixel-density printing
