Problems solved by technology

If the resolution is further increased, the sub-pixel size will be further reduced, and it will be difficult to control the ink in each sub-pixel to be independent from each other without overflowing the pixel pit, so it is more difficult to realize the printing preparation of high-resolution display devices

Abstract

The invention discloses a pixel defining structure, a manufacturing method for the same, a display panel and a display apparatus. The pixel defining structure comprises a first pixel defining layer and a second pixel defining layer arranged on the first pixel defining layer, wherein the pixel defining layer is provided with a plurality of first openings one-to-one corresponding to each sub-pixel illuminating area; and the second defining layer is provided with a plurality of second openings co-used by sub-pixels having the same color. Ink can be prevented from overflowing due to excessive small area of single sub-pixel and size of each sub-pixel can be relatively reduced; effectiveness of printing technology can be guaranteed; ink can be prevented from overflowing due to excessive small area of each sub-pixel during the printing process; and limitation of high-definition display component preparation by the printing technology can be solved, and the printing high-definition display component can be manufactured.

Description

technical field [0001] The present invention relates to the field of organic light-emitting display technology, in particular to a pixel defining structure and manufacturing method, a display panel and a display device. Background technique [0002] The use of solution processing to manufacture OLED and QLED displays is an important direction for the future development of display technology due to its advantages of low cost, high productivity, and easy realization of large sizes. Among them, printing technology is considered to be the most effective way to realize OLED and QLED low-cost and large-area full-color display. [0003] In the printing process, due to the influence of equipment precision and droplet size, for the traditional RGBStripe (RGB strip) arranged pixel structure (such as figure 1 As shown), when the resolution of the display device reaches 200ppi, the width of each sub-pixel will be reduced to 42μm. At the same time, due to the existence of the pixel defi...
