Abstract
An organic light emitting display device includes a driver to drive at least one pixel. The driver drives the pixel based on a frame which includes at least one data sub-frame and at least one hysteresis reset sub-frame. The driver applies an emission data voltage or a non-emission data voltage to the pixel during the data sub-frame, and applies a reset voltage to reset a driving transistor of the pixel during the hysteresis reset sub-frame. The reset voltage may initialize a voltage-current characteristic of the driving transistor during the hysteresis sub-frame.
