A pixel includes an organic light emitting diode and a pixel circuit. The pixel circuit includes a first transistor to control current from a first power source to the OLED based on a voltage applied to a first node, and a second transistor connected between the first node and a data line, the second transistor to turn on based on a scan signal applied to a scan line. The pixel circuit also includes a controller to supply a voltage from a power line to at least one of the first node or an anode electrode of the OLED.
