Abstract

A gate driver includes a first scan signal generator configured to output a logic voltage for driving of a scan transistor through a plurality of stages connected in cascade, the scan transistor performing a switching operation to transfer a data voltage to a driving transistor of a pixel, a second scan signal generator configured to output a logic voltage for driving of a sensing transistor through the plurality of stages, the sensing transistor sensing deterioration of a light emitting element of the pixel, a light emission control signal generator configured to output a logic voltage for control of a light emission control transistor of the pixel through the plurality of stages, and an initialization voltage generator driven by logic voltages received from some nodes of the first scan signal generator based on the light emission control signal generator to supply an initialization voltage to the pixel.
