Flexible OLED display would be one of the most popular display type in the future. However there are many challenges before the mass production ability matured. Flexible substrate preparation, Lower temperature w/ LTPS (L-LTPS), thin film encapsulation and flexible module process are discussed separately in this paper. The difficulties of each process were pointed out and provide some solution for reference. We improve and apply the solution in our 4.35"~10.9" flexible OLED sample.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
