Abstract
In this paper, a scan driver with extra clock signal using amorphous indium-gallium-zinc-oxide (a-InGaZnO) thin-film transistors (TFTs) is proposed. Extra clock signal with variable frequency modulates the pull-down unit of scan driver in order to reduce the power consumption. Proposed scan driver is suitable for operating extreme low-power displays such as always on display.
