Abstract
A pixel having a simplified structure can compensate for the threshold voltage of a driving transistor thereof. The pixel includes an organic light emitting diode (OLED) having a cathode electrode coupled to a second power source, a storage capacitor coupled between a data line and a first node, a second transistor having a first electrode coupled to a first power source, a second electrode coupled to an anode electrode of the OLED, and a gate electrode coupled to the first node, a first transistor coupled between the first node and the second electrode of the second transistor, a gate electrode of the first transistor being coupled to a current scan line, and a third transistor coupled between the second electrode of the second transistor and the anode electrode of the OLED, a gate electrode of the third transistor being coupled to a control line.
