In this paper, a scan driver combined with logic circuit using amorphous indium-gallium-zinc-oxide (a-InGaZnO) thin-film transistors (TFTs) is proposed. Logic circuit masks the output signal from the scan driver in order to control the driving frequency. Proposed frequency adaptive scan driver is expected to reduce power consumption depending on the display contents.
