Abstract
An organic light emitting display comprises a display panel having a plurality of pixels, a gate drive circuit that drives scan lines and emission lines on the display panel, and a data drive circuit that drives data lines on the display panel. Each of the pixels is arranged in an nth row. A single frame for the organic light emitting display comprises an initial period in which the gate voltage of a driving transistor is initialized, a sampling period for compensating the threshold voltage of the driving transistor, and a light emission period in which an organic light emitting diode emits light. A value corresponding to an image signal to be displayed by the organic light emitting diode is applied to a data line during the sampling period, and an initial voltage is applied to one electrode of a capacitor during the initial period.
