Technical Field

The present invention relates to the field of electronic display technologies, and in particular, to a pixel arrangement structure, a light emitting device, and a display panel.

Background

At present, the OLED display has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, lightness, thinness, etc., and becomes the mainstream of future display. The way to realize full color display is to deposit organic light emitting material and process solution. The evaporation coating of organic luminescent material independent luminescence is the most adopted way to realize full color display at present, and mainly utilizes the precise metal shadow mask and pixel contraposition technology to prepare red, green and blue luminescent layers by the evaporation coating method. The solution processing for manufacturing the display is an important direction for the development of the future display technology, especially the printing process, due to the advantages of low cost, high productivity, easy realization of large size and the like. However, as the display technology is continuously developed, the resolution of the display panel is higher and higher, and the method of evaporation is limited by the accuracy of the dimension of the shadow mask pattern, so that the resolution of the display prepared by the method is limited. To realize high-resolution products, pixels are usually designed to be small, which puts a severe requirement on printing equipment, and current printing equipment cannot meet the requirement of high-pixel-density printing.
