Abstract
In this work, a commercial foldable display of 8.0‐inch 2K AMOLED(Active Matrix Organic Light‐emitting Diode) was developed for foldable smart phones. By considering commercial requirements for a brand new product, fundamental performances are introduced. By new design concepts, display and touch performances are guaranteed, while the foldable reliabilities are also achieved to a commercial goal. Not only how to improve the bending abilities, but also the mechanical abilities of foldable display module are discussed. In bending performance, the endurance of dynamic folding and static folding are treated by different ways. The materials and layer stacks optimization are discussed. The root causes of the deformation in foldable display are analyzed. Solutions for the out‐folding display is suggested.
