P‐155: Research on Redundancy Absorption and Surface Deformation of OLED Display

AMOLED (Active‐matrix organic light‐emitting diode) is supported by PI (Polyimide) flexible substrate, which can be made into an arbitrary shape. It will cause area difference in hyperboloid or spherical CG (Cover Glass) when it is laminated to the surface. In this case, the wrinkles will occur on the bending surface. In this article, the influencing factors are analyzed by building a model in stress simulation software to compute the minimum principal stress. Besides, the design of experiment about avoiding wrinkles are done.
