Abstract
A light emission control driver includes a first logic unit configured to receive a plurality of clock signals and a first input signal and generate a first output signal; a second logic unit configured to receive a plurality of clock signals and a second input signal and generate a second output signal; and an output controller configured to receive the first output signal, the second output signal, a first control signal, and a second control signal, and generate a light emission control signal. When a driving scheme of a display unit is a simultaneous light emission mode, the light emission control signal is controlled according to driving of the output controller, and, when the driving scheme of the display unit is a progressive light emission mode, the light emission control signal is controlled according to driving of the first logic unit, the second logic unit, and the output controller.
