Abstract
In this paper, we propose a scan driver with an extra clock signal using amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs). By employing extra clock signal modulation-based frame masking driving and constant DC driving methods, the proposed scan driver achieves extremely low power consumption while simultaneously reducing the power consumption of the display panel. The proposed novel scan driver is suitable for operating ultra-low-power displays, such as always-on displays.
