Abstract:
An emission control driver includes a plurality of stages configured to output a plurality of emission control signals, respectively. Each stage includes an input circuit for receiving a previous emission control signal from one of previous stages or a vertical start signal, and configured to control a voltage of a first node and a voltage of a second node in response to a first clock signal; a stabilizing circuit for stabilizing the voltage of the first node in response to the voltage of the second node and a second clock signal; a voltage adjusting circuit connected between the second node and a third node, configured for boosting the voltage of the second node, and controlling the boosted voltage of the second node; and an output circuit configured to control an emission control signal in response to the voltage of the first node and a voltage of the third node.
