P‐157: Finite Element Analysis and Optimization Study of Ultra‐Thin Glass Cracks in Flexible Displays

This paper investigates the crack issues of Ultra‐Thin Glass (UTG) in flexible displays. By establishing a finite element model, the influence of the thickness and modulus of each layer in the laminated structure on the stress distribution of UTG is systematically analyzed. The study found that the modulus of OCA0, the modulus of OCA1, the thickness of PI1/PET1, and the thickness of OCA1 are the main factors affecting UTG stress. Based on this, optimization strategies to reduce UTG stress are proposed, including increasing the modulus of OCA1, reducing the modulus of OCA0, and decreasing the thickness of PI1/PET1. This study provides a theoretical basis for the structural optimization design of flexible displays.
