GATE DRIVER AND ELECTROLUMINESCENCE DISPLAY DEVICE USING THE SAME

Abstract:

A disclosed gate driver includes a plurality of stages, a k.sup.th stage comprising: a first output node connected to an emission line; a second output node; a Q node connected to a first controller and a pull-down circuit; the pull-down circuit and a pull-up circuit respectively controlled by the Q node and the second output node; the first controller configured to receive a voltage of a first output node of a (k-1).sup.th stage or a first start signal; a second controller configured to receive a voltage of a second output node of the (k-1).sup.th stage or a second start signal; a third controller configured to control the voltage of the second output node; and a fourth controller configured to be controlled by the second output node and to control the voltage of the first output node, wherein `k` is a natural number .gtoreq.1.
