Abstract
There is provided a pixel, including an organic light emitting diode (OLED), a first transistor whose gate electrode is coupled to a first node, whose first electrode is coupled to a first power supply via a third node, and whose second electrode is coupled to an anode electrode of the OLED, a second transistor coupled between a data line and a second node and turned on when a scan signal is supplied to a scan line, a first capacitor coupled between the second node and a first voltage source, a third transistor coupled between the second node and the first node and turned on when a second control signal is supplied, and a fourth transistor coupled between the first node and the first power supply and turned on when a first control signal is supplied.
