Development of Foldable AMOLED Displays Based on Neutral-Plane Splitting Concept

56‐3: Quantitative Evaluation of Neutral‐plane Splitting in Foldable Displays Using Folding Stiffness Measurements and Finite Element Method Simulations

“…Foldable displays with low stiffness require little force by users for folding. We demonstrated that neutralplane splitting reduces the folding stiffness and improves usability of foldable displays [8].…”

“…It looks quite simple, but there are additional layers like Optically Clear Adhesive (OCA) to be placed between. In order to fold this display, firstly overall module thickness should be reduced over 60% while allowing the emission layer to be located on the neutral plane (i.e., generic flexible OLED module thickness is 1115mm while foldable module thickness target is below 400mm) [4]. Since the other layers located above and below must be exquisitely symmetrical and each function and robustness must be maintained, it requires to optimize the whole system not just individual layers.…”
