■A word of caution in manufacturing of OLED with flexible substrate
Case of using flexible substrate with film shape
OLED is manufactured on original substrate, and then transferred to plastic filmResin is coated on support substrate and cured, and then, TFT and OLED are manufactured on resin film, finally, support substrate is released (The resin film is used as substrate)
