Reliability study of flexible display module by experiments

Abstract

Flexible display module reliability were investigated herein with experiments, such as bending, twisting and ball drop. The pretests of all the three experiments were carried out firstly to primarily understand the flexibility and mechanical behavior of the display. Based on the pretest results, the corresponding fatigue test setup method and process were put forward. Then, the fatigue tests were executed. At last, through the failure analysis, the flexibility and reliability of the flexible display in different use cases were evaluated. Suggestions about how to use the display and improve the reliability through change the design were given also.
