61.3: Amorphous Silicon TFT Technology for Rollable OLED Displays

Abstract Amorphous silicon thin‐film transistors were designed for roll‐out OLED screens in hand‐held devices. Separate TFTs reached a saturation current of 6 μA/square, an output current half‐life extrapolating to 1,000 years, and were rolled to 1 mm diameter. All three parameters set new world records.
