P‐55: Research and Application on the Hanging Ear Fracture of Optical Film for Vehicle Display Module

In recent years, large‐screen and multi‐screen have become the mainstream trend in the development of vehicle display module, and vehicle display module is an important component of modern car. As the module becomes larger, the hanging ear of module film is more prone to be broken, leading to abnormal display. This paper simulates the vibration testing of module film and quickly and effectively assess the risk of high and low temperature random vibration testing, providing film design guide through finite element analysis, studying the effects of the hanging ear design parameters on fatigue fracture, and combining the high and low temperature S‐N curve of the film material.
