Abstract: A pixel capable of displaying an image with uniform brightness is disclosed. In one aspect, the pixel includes an organic light emitting diode (OLED), a first transistor for controlling an amount of current that flows from a first power supply to a second power supply via the OLED in response to a voltage applied to a first node. The pixel also includes a second transistor that is coupled between a bias power supply and the first node and whose gate electrode is coupled to an emission control line. The pixel further includes a third transistor that is coupled between an anode electrode of the OLED and a feedback line and whose gate electrode is coupled to a control line.

Abstract: A display device includes a display panel, a scan driver outputting a scan signal, and a data driver. The scan driver includes a first sub-scan driver that receives a first start signal and an odd clock signal, and a second sub-scan driver that receives a second start signal and an even clock signal. The scan signal has an activation period corresponding to a horizontal period. The odd clock signal includes a first clock enable period and a first clock disable period, which are ‘k’ times greater than the horizontal period. The even clock signal includes a second clock enable period and a second clock disable period, which are ‘k’ times greater than the horizontal period. The first clock enable period and the second clock enable period alternate with one another.
