  • Patent number: 9343011
    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.
