For the first time in the world, we have fabricated OLED display that monolithically integrates Si CMOS, oxide semiconductor FETs, and OLED devices. The panel fabricated is a thin-bezel, > 5000 ppi OLED display with drivers embedded in the display area, enabling area savings of up to approximately 40%
