Dr. Jianping Chen SID19 Foldable


Recently, foldable smartphones have received quite attentions and are poised to shape the smartphone market in the foreseeable future, thanks to the defining form factor-folding/unfolding. A key component that plays a pivotal role in helping the foldable smartphone commercial launch is the Active-Matrix Organic Light-Emitting Diode (AMOLED) display module.

In this presentation, we will discuss the AMOLED display technology evolution, from its rigid and flat form, to the various flexible forms, curved, bendable, foldable, and rollable formats. A special focus will be on the foldable AMOLED display module, its material’s selection (cover window film, circular polarizer, touch sensor, adhesive, etc.) and system integration (hinge design, UX, App., ergonomics, reliability, etc.), when facing different folding formats, in-folding vs. out-folding. In addition, we will also present Visionox’s flexible AMOLED development status and its pathforward.
