Patent ID: 8314788

Claim:
An organic light emitting display device comprising: a scan driver configured to sequentially supply a scan signal to a plurality of scan lines, to sequentially supply a control signal to a plurality of control lines, and to sequentially supply a light emitting control signal to a plurality of light emitting control lines; a data driver configured to supply a data signal to a plurality of data lines; and a plurality of pixels, each pixel comprising: an organic light emitting diode; a second transistor connected to one of the scan lines and one of the data lines and configured to be turned on when the scan signal is supplied thereto; a first transistor connected between a second electrode of the second transistor and the organic light emitting diode, the first transistor configured to control a current which flows from a first power source to a second power source through the organic light emitting diode, wherein the first transistor is configured to be selectively diode-connected by the light emitting control signal; a storage capacitor having one terminal connected to a gate electrode of the first transistor and the other terminal connected to one of the control lines, wherein the other terminal is configured to receive the control signal from the one control line; and a third transistor connected between a gate electrode and a second electrode of the first transistor, the third transistor configured to be turned on when the light emitting control signal is supplied thereto.
