P‐15.16: Evaluation of the Waviness of Foldable AMOLED Display through Nonlinear Mechanical Constitutive Model of OCA

AMOLED flexible display are becoming popular, but the waviness in the middle of the display screen has greatly affected the user experience. Waviness will become more visible with the usage time, which is still the main concern of foldable products in the display industry. But the middle crease has become one of the main reasons why the sales of folding mobile phones have not been popular as present, mainstream mobile phone and screen manufacturers are in the analysis stage of Waviness mechanism. Therefore, this article mainly analyzes the causes of waviness in the folding screen from multiple factors, and draws its main influence mechanism. In this paper, based on the theoretical analysis and simulation results, the development direction of Film and OCA properties is proposed, which provides the possibility for the waviness‐free foldable AMOLED display.
