58‐2: Structurally Anisotropic Backing Sheets for Rollable‐Foldable Display Modules

Abstract

While perforated‐slot backing plates are universally used to ruggedize today's foldable OLED display modules, we investigated an alternative approach incorporating freestanding ribs connected by a low modulus spring material. We explore manufacturing options and offer a closed‐form structural analysis of both types to inform applications of the alternative approach.
