ABSTRACT:
An emission control driver that applies an emission control signal for controlling an emission operation of a pixel circuit is provided. The emission control driver includes an emission control circuit with a plurality of transistors and a capacitor placed between a positive power supply voltage and a negative power supply voltage. When the driver is fabricated in an organic light emitting display (OLED), the transistors send a high level or low level emission control signal to a pixel circuit in response to a scan signal, and can be the same type transistors as the pixel circuit transistors. Further, the emission control driver may include a transistor for interrupting the positive power supply voltage in response to an initializing signal to initialize a capacitor of the pixel circuit.
