Abstract:
An emission driver includes light emission driving controllers that are electrically connected to light emission control lines. Each of the light emission driving controllers may include a first circuit block configured to provide a second voltage to a first node in response to a first clock signal and to output a first voltage as a light emission control signal based on a voltage at the first node and a second clock signal having a phase difference from a phase of the first clock signal; and a second circuit block configured to provide a synchronization signal to a second node in response to the first clock signal, to maintain a voltage at the second node using a metal-oxide-semiconductor (MOS) capacitor, and to pull down the light emission control signal to have the second voltage in response to the voltage at the second node.
