摘要： An organic light emitting display and a driving method thereof, in which an image is displayed with uniform brightness. The organic light emitting display includes: a scan driver for supplying a plurality of first scan signals at substantially a same time to a plurality of scan lines in a first period of one frame and for supplying a plurality of second scan signals in sequence to the scan lines in a second period of the one frame; a data driver for supplying a predetermined voltage to a plurality of data lines in the first period and for supplying a plurality of data signals to the data lines in the second period; and a pixel portion comprising a plurality of pixels connected to the scan lines and the data lines, wherein, when the one frame is an odd-numbered frame, the scan driver supplies the second scan signals in a first scanning sequence and wherein, when the one frame is an even-numbered frame, the scan driver supplies the second scan signals in a second scanning sequence differing from the first scanning sequence. With this configuration, a threshold voltage difference between the pixels is stably compensated. Further, in one embodiment, the first scanning sequence is inversely related to the second scanning sequence, so that the emission times of all pixels are equalized on average.
