P‐118: Optimization of Folding Process for Flexible Electronic Device

Recently, the folding process has attracted considerable attention for bezel‐less construction in flexible display field. From chip on glass (COG) to chip on plastic (COP), the bezel has been greatly reduced yet needing a more optimized technology to keep a high yield rate. In this study, a folding‐trajectory optimization of the minimum radius of flexible substrate electronics device could be defined by using simulation even if the final folding area is exactly the same. Two different concepts of folding trajectory model and five different folding radius functions of time were simulated in this study for the selection of the best folding trajectory.
