Title
(EN) Foldable display neutral axis management with thin, high modulus layers
Abstract
(EN)

A foldable display of a computing device includes a back stiffening layer, a transparent frontplate layer, a transparent cover window layer, and an OLED display layer disposed between the back stiffening layer and the transparent frontplate layer. The OLED display layer characterized by a Young's modulus that is lower than the Young's modulus of the transparent frontplate layer and that is lower than the Young's modulus of the back stiffening layer; a neutral plane of the foldable display is located within the OLED display layer.
