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 scan driving device includes shift registers, each including a first signal terminal to which a forward direction driving start signal is transferred, a second signal terminal to which a backward direction driving start signal is transferred, a clock signal terminal and a clock bar signal terminal to which a clock signal and a clock bar signal are applied, a sustain signal terminal to which a sustain signal is transferred, a control signal terminal to which a control signal is transferred, a gate clock signal terminal to which a gate clock signal is transferred, and an output signal terminal, where driving power source voltages including a high potential power source voltage and low potential power source voltages is applied to each shift register, and an application of the low potential power source voltages to each shift register is controlled based on the sustain signal.
