Patent ID: 8902208

Claim:
An organic light emitting display device comprising: a scan driver for sequentially supplying, during each horizontal period of a first width 1H, a scan signal with a second width of at least 2H to scan lines so that the scan signal supplied to a previous one of the scan lines partially overlaps with the scan signal supplied to a current one of the scan lines for a period having a third width, the scan driver being further for sequentially supplying an emission control signal to emission control lines substantially parallel to the scan lines; a data driver for supplying data signals to data lines; and pixels each comprising an organic light emitting diode (OLED), a pixel circuit comprising a first transistor for controlling an amount of current supplied to the OLED, and a compensator for controlling a voltage of a gate electrode of the first transistor for compensating a degradation of the OLED, the compensator comprising two transistors, wherein one of the two transistors is coupled to one of the scan lines, and an other of the two transistors is coupled to one of the emission control lines.
