摘要： An organic light emitting display device includes a scan driver, a data driver, and pixels. The scan driver is for sequentially supplying, during each horizontal period of a width 1H, a scan signal with a width of at least 2H to scan lines. The scan driver is further for sequentially supplying an emission control signal to emission control lines that are substantially parallel to the scan lines. The data driver supplies data signals to data lines. Each pixel includes an organic light emitting diode (OLED), a pixel circuit having a first transistor for controlling the amount of current supplied to the OLED, and a compensator for controlling the voltage of a gate electrode of the first transistor for compensating a degradation of the OLED. The compensator includes two transistors and a capacitor. One transistor is coupled to a scan line, and the other is coupled to an emission control line.
