Abstract:
An emission driver includes stages outputting an emission control signal. At least one of the stages includes an input circuit controlling voltages of a first node and a second node, an output circuit supplying a voltage of first power or a voltage of second power to an output terminal as the emission control signal in response to a voltage of a third node and a voltage of a fourth node, a first signal processor controlling the voltage of the fourth node, a second signal processor controlling the voltage of the fourth node, and a third signal processor controlling the voltage of the third node electrically connected to the first node in response to signals supplied to the second input terminal and the third input terminal and the voltage of the first node.
