Abstract
An pixel of an organic light emitting display device includes: an organic light emitting diode (OLED); a second transistor for supplying a current to the OLED; a first transistor coupled between a data line and a gate electrode of the second transistor, the first transistor being turned on when a scan signal is supplied to its gate electrode; a third transistor for supplying an initialization voltage to a drain electrode of the second transistor, the third transistor being turned on when a control signal is supplied to its gate electrode; a fourth transistor coupled between the drain electrode of the second transistor and a first power supply, the fourth transistor being turned-off when a light emitting control signal is supplied to its gate electrode and turned-on when the light emitting control signal is not supplied; and a storage capacitor coupled between the source and gate electrodes of the second transistor.
