Abstract

A 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 to correspond to a voltage applied to a first node, a second transistor coupled between an anode electrode of the OLED and a feedback line, and having a gate electrode coupled to a control line, a third transistor coupled between the first node and a data line, and having a gate electrode coupled to a first scan line, a storage capacitor coupled between the first node and a second node, and a fourth transistor coupled between the second node and a reference power supply, and having a gate electrode coupled to a second scan line.
