Abstract
A gate driver includes stages. Each stage includes: a first output part for outputting a carry signal in response to a voltage of a first node; a first input part for controlling the voltage of the first node in response to a previous carry signal; a second input part for controlling the voltage of the first node in response to a first next carry signal; a second output part for outputting a scan signal in response to the voltage of the first node; a third output part for outputting a sensing signal in response to the voltage of the first node; and a scan signal control part for applying a first low power voltage to an output terminal of the second output part to which the scan signal is output in response to a second next carry signal of which a pulse is generated before the first next carry signal.
