STAGE CIRCUIT AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

A driver includes a first circuit to output a scan signal and a second circuit to output an emission control signal. The first circuit outputs the scan signal based on a first set of clock signals, and the second circuit outputs the emission control signal based on a second set of clock signals. The first set of clock signals and the second set of clock signals have at least one same clock signal and at least one different clock signal. The second circuit receives the scan signal and outputs the emission control signal based on the scan signal. The first circuit may be a scan driver and the second circuit may be an emission control driver of a display device.
