18.3: Low Power 3.4inch Quarter High Definition OLED Display Using InGaZnOxide TFTs and White Tandem OLED

We recently succeeded in manufacturing a 3.4 inch QHD OLED display 326ppi with high aperture ratio, 40%, in which we adopted the white OLED using a tandem structure and a color filter method. Besides, we achieved 40% lower the power consumption of the driver circuit 60mW by improving it.
