Flexible display multilayer structure functional layer spray printing preparation method and system

Abstract

The invention belongs to the related field of jet printing display technology, and discloses a flexible display multilayer structure functional layer jet printing preparation method and system, which comprises a liquid drop flight and deposition visual detection module, a liquid drop fusion measurement module, a box body and support module, a first jet and control module and a second jet and control module, and through design cooperation of a plurality of modules, operations such as liquid drop flying deposition dynamic process observation, liquid drop fusion measurement and thickness measurement of each functional layer are realized, and closed-loop control of preparation of the functional layers of the flexible display multilayer structure is realized by fully utilizing acquisition data of different key modules. According to the invention, a liquid drop flight process mechanism, a liquid drop dynamic deposition process mechanism, liquid drop fusion volume measurement and functional layer film thickness measurement can be effectively explored, complete monitoring of the full life cycle of liquid drops is realized, and efficient control of technological processes of different spraying modules is completed. And the quality and the production and preparation yield of the flexible display multi-layer structural member product are remarkably improved.

Description

technical field

[0001] The invention belongs to the technical field of jet printing and display, and more particularly, relates to a preparation method and system for jet printing of a multi-layer structure and functional layer of a flexible display. Background technique

[0002] New display devices have received more and more attention in the industry due to their excellent display characteristics. Considering the fabrication cost, fabrication efficiency, and portability of new display devices, display device fabrication systems must be developed in the direction of ultra-high resolution display devices, large display substrate sizes, flexible display substrates, and low-cost production processes. The traditional coating-based display manufacturing technology cannot meet the requirements of large-area, high-efficiency, and low-cost fabrication of new display devices due to process complexity and high cost. Therefore, a new process fabrication method is urgently needed. [...
