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. [...

AI Technical Summary

Problems solved by technology

[0005]Although some existing technologies consider realizing the above-mentioned closed-loop control of printing based on various detection data, there are still some problems: detection data (including fusion droplets after printing) Volume measurement data) are relatively independent, and there are relatively few measurement objects, and closed-loop control is only applicable to one process or single-layer structure, which cannot meet the quality control of multi-layer structure preparation

[0006] Therefore, the existing closed-loop control method cannot meet the high-efficiency and high-quality jet printing preparation of the multi-layer structure functional layer of the flexible display, and it is urgent to improve the existing closed-loop control flexible display , in order to realize the high-efficiency and high-quality jet printing preparation of flexible display multi-layer structure functional layers
