Abstract
A pixel circuit may include a pixel unit coupled to a crossing point of a data-line and a scan-line, the pixel unit receiving a first power source voltage and a second power source voltage that are DC power source voltages, an organic light emitting diode coupled to the pixel unit, and a light emitting control transistor coupled between the pixel unit and the organic light emitting diode. Here, the light emitting control transistor may periodically turn on and off in response to a light emitting control signal having a logic high level and a logic low level in a frame, and the light emitting control signal may be simultaneously provided to a plurality of light emitting control transistors in a display panel.
