Abstract

AbstractThe 5.98 inch‐sized World's first flexible OLED display has been developed and launched mass production on smartphone with extremely light, thin and curved shape, successfully. We have employed ELA‐TFT on PI backplane, Face‐sealing encapsulation, Laser‐assisted glass release and flexible back‐plate lamination process. These technologies enable panel reliability as well as mass production with inherent flexible display characteristics. For commercializing flexible OLED, technical barriers and challenges on TFT device, panel design and various process technologies including LG Display's recent experience will be presented in this paper.
