P‐7.4: Research on the Application of Liquid Optically Clear Adhesive for Foldable OLED

Abstract

This study explores the application of Liquid Optical Clear Adhesive (LOCA) in flexible display modules using inkjet printing technology. We started by selecting and testing the printing and mechanical characteristics of the LOCA material, ultimately determining the optimal viscosity window and suitable LOCA material for our needs. Next, we established the inkjet printing process for LOCA and validated the curing process based on peel strength results. Finally, we produced folding modules using LOCA and conducted folding tests, which demonstrated satisfaction of the 200,000‐cycles folding requirement.
