US Patent 11770907 Support film layer and flexible display panel

The present application discloses a support film layer and a flexible display panel. By periodically arranging at least one elliptical hollow structure and a plurality of shuttle-shaped hollow structures in a bending region of the support film layer, stress concentrations in the bending region can be weakened, which is beneficial to increase a bending lifespan of the support film layer. The present application can improve an overall ductility of the flexible display panel, increase a bending performance of the flexible display panel, reduce a risk of peeling and fracture between film layers, and increase production yields of products.
