P‐4.4: Path Planning Analysis of Pad Bending Process for the Full Screen OLED Panel

In the pad‐bending process of the full‐screen panel, the metal wire in the bending area is easily broken due to deformation, and the occurrence of the break is related to the bending path. This paper analyzes the influence of different bending paths on the peak stress of the metal wire, determines the method to explore the reasonable path based on mathematical theory, and provides guidance for the pad‐bending process design, which can be used to improve the yield of pad‐bending process of OLED panels.
