P‐154: Four‐Edge Deeply Curved AMOLED Display

The 4‐ edge curved display is one kind of flagship form of flexible display. In this paper, we study the effect of materials and back plate film (BPF) patterning on winkle effect of 4‐ edge curved display. By optimizing materials and pattern design of module stacking, the bending degree is improved obviously. In addition, a wrinkle prediction model is established, and the actual wrinkle degree can be predicted by CAE.
