Abstract: A pixel includes an organic light emitting diode (OLED), a pixel circuit, and first and second transistors. The OLD includes a cathode electrode connected to a second power source. The pixel circuit includes a driving transistor having a gate electrode initialized by a third power source. The driving transistor controls the amount of current flowing from a first power source to the second power source via the OLED. The first transistor is connected between a fourth power source and the second power source and an anode electrode of the OLED. The first transistor is turned on based on a scan signal is supplied to a scan line. The second transistor is connected between a data line and the pixel circuit. The second transistor is turned on when the scan signal is supplied to the ith scan line.
