Abstract

The invention discloses a printed pixel bank structure and a preparation method thereof. The pixel bank structure comprises a substrate, a pixel electrode and a pixel bank, wherein the substrate, the pixel electrode and the pixel bank are successively arranged from bottom to top. The pixel bank is obtained through stacking at least three bank layers. The lyophobicity of at least three bank layers gradually increases from bottom to top, and lyophily gradually reduces from bottom to top. According to the printed pixel bank structure, the pixel bank is formed through stacking at least three bank layers with different lyophily and different lyophobicity. Through designing the multiple bank layers, a plurality of boundaries with different lyophily and different lyophobicity can be formed, thereby forming pinning points at different positions for different kinds of ink, and effectively controlling uniformity of different printing film layers.

Description

technical field [0001] The invention relates to the field of printing, in particular to a printed pixel bank structure and a preparation method thereof. Background technique [0002] OLED and QLED displays are produced by solution processing, which has the advantages of low cost, high productivity, and easy realization of large size, and is an important direction for the development of display technology in the future. 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] However, as an emerging technology, solution printing technology and printing process have not been well resolved. Although researchers have improved it from the material jet printing equipment, printing problems such as the stability of the printing equipment and the uniformity of film thickness have not been able to achieve the expected results. [0004] In the process of printing process development, the ...
