Abstract

A gate driver can include a plurality of stages, each of the plurality of stages including a transistor Tconfigured to apply a start signal of a gate-on voltage to a node Q in response to a clock signal and activate the node Q; a transistor Tconfigured to supply an emission signal of the gate-on voltage to an output node when a node QA is bootstrapped in synchronization with a timing at which the node Q is activated; a QB controller configured to activate a node QB based on the clock signal, the start signal and a voltage of the node Q; and a transistor Tconfigured to supply the emission signal of a gate-off voltage to the output node while the node QB is activated prior to activation of the node Q.
