Abstract
We demonstrate the level shifter integrated gate drive circuits using Low-Temperature Poly-Si (LTPO) TFT technology. Three level shifters are integrated with a 16-stage 2-clock CMOS shift register. A low 5 V start pulse is level up to a high 20 V for gate driving operation. The 4 s pulse width ensures its speed compatibility to drive an Ultra-High Definition (UHD) 4K displays (3840 X 2160 @ 60 Hz).
