The key materials and devices for intrinsically flexible displays

This review is conceived by academician Yunqi Liu and professor Yunlong Guo (Institute of Chemistry, Chinese Academy of Sciences). Dr. Zhiyuan Zhao, Dr. Kai Liu, and Yanwei Liu are the co-first authors. This research attaches significant attention to the key materials for intrinsically flexible organic thin film transistors (OTFTs) and electroluminescent devices. Specifically, we focus on the following five aspects: intrinsically flexible electrode materials, organic semiconductors (OSCs) and dielectric materials for OTFTs, intrinsically flexible organic emissive semiconductors (OESCs) for electroluminescent devices, and OTFT-driven electroluminescent devices for intrinsically flexible displays. Lastly, the future challenges and opportunities about intrinsically stretchable OTFT-driven displays are presented.
