Abstract
In this paper, a low-power scan driver using depletion-mode amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs) is proposed for high-resolution displays. The proposed scan driver uses single clock signal to reduce the power consumption. This scan driver is simulated at the operating frequency of 153.6 kHz, which is the driving condition of 10.0-inch wide quadruple extended graphics array (WQXGA, 1600 × 2560) display with the frame frequency of 60 Hz. The power consumption of ten stages of the proposed circuit is 0.39 mW. The proposed scan driver reduces the power consumption by 69% compared to the conventional scan driver.
