SUPPORT FILM LAYER AND FLEXIBLE DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2022/088319
Kind Code:
A1
Abstract:
A support film layer (20) and a flexible display panel. The alternate arrangement of at least one elliptical hollow structure (230) and a plurality of spindle-like hollow structures (210) in a bending region (200) in the support film layer (20) can weaken the stress concentration in the bending region (200), thereby improving the bending service life of the support film layer (20), improving the overall ductility of the flexible display panel, improving the bending performance of the flexible display panel, reducing the risks of debonding between film layers and fracture, and improving the production yield of products.
