Abstract
A pixel includes first through fourth transistors and storage capacitor. The first transistor controls an amount of current flowing from a first driving power source to a second driving power source, via an organic light-emitting diode, based on a voltage of a first node. The second transistor is coupled between a first electrode of the first transistor and the first node, and is turned on when a scan signal is supplied to a scan line. The third transistor is coupled between a second electrode of the first transistor and a reference power source, and is turned on when the scan signal is supplied. The fourth transistor is coupled between an anode electrode of the organic light-emitting diode and a data line, and is turned on when the scan signal is supplied. The storage capacitor is coupled between the first node and the anode electrode of the organic light-emitting diode.
