Abstract

The invention provides a pixel bank structure suitable for preparing a display by a printing process and a preparation method thereof. A pixel bank structure suitable for preparing a display by a printing process, including a substrate, a patterned pixel electrode, and a pixel bank layer, the pixel bank layer including a first pixel bank arranged on the substrate and a first pixel bank arranged on the first pixel bank The second pixel Bank on the surface, wherein the first pixel Bank is a Bank structure with a narrow top and a wide bottom, and the first pixel Bank is made of a lyophilic material; the second pixel Bank includes a pair of mutual offset The height of the ink guiding slope is gradually increased along the direction in which the mutually abutting ink guiding slopes approach each other, and the second pixel Bank is made of a liquid-repellent material.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a pixel bank structure suitable for printing a display and a preparation method thereof. Background technique [0002] OLED (Organic Light Emitting Diode) and QLED (Quantum Dot Light Emitting Diode) displays are produced by solution processing. Due to their advantages of low cost, high productivity, and easy realization of large size, it 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, OLED or QLED prepared by solution printing technology and printing process have the problem of poor display effect. Although researchers have improved it from the perspective of materials and printing equipment, printing problems such as the stability of printing eq...
