Abstract
A pixel includes an organic light emitting diode; a first transistor; a second transistor coupled to a data line and turned on when a scan signal is supplied to an iscan line; a third transistor between the second transistor and a gate electrode of the first transistor and turned on when a scan signal is supplied to an i+1scan line; a fourth transistor between the gate electrode of the first transistor and a reference power supply and turned on when the scan signal is supplied to the iscan line; a fifth transistor between the organic light emitting diode and an initial power supply and turned on when a control signal is supplied; a first capacitor between the organic light emitting diode and a node between the second transistor and the third transistor; and a second capacitor between the node and the gate electrode of the first transistor.
