37‐2: Development of high mobility top gate IGZO‐TFT for OLED display.

We report the high performance top gate IGZO‐TFT for OLED display. By optimizing the conditions of process, we fabricated the transistor with mobility from 7 to 32 cm 2 /Vs with enhanced threshold voltage. They also have reliability PBT/NBT enough to use application. Finally, the prototype 12.3” ultrawide flexible OLED display was successfully demonstrated.
