Abstract
An emission driver is disclosed. The emission driver includes a Q node controller configured to control a voltage at a Q node by applying a start signal, a carry signal, or a high-potential driving voltage to the Q node responsive to a first clock signal, a QB node controller configured to control a voltage at a QB node by applying the high-potential driving voltage or a low-potential driving voltage to the QB node responsive to the first clock signal, an output buffer configured to output the high-potential driving voltage or the low-potential driving voltage to the corresponding emission line responsive to the voltages at the Q node and the QB node, and a pump controller configured to change the voltage at the Q node according to a second clock signal while the emission signal is output at a turn-on level responsive to the start signal or the carry signal.
