Abstract: An organic light emitting display including pixels, a scan driver, a data driver, a control line driver, and a compensation unit. The pixels are positioned in an area defined by data lines, scan lines, and control lines, and each includes an organic light emitting diode. The scan driver drives the scan lines. The data driver drives the data lines. The control line driver drives the control lines. The compensation unit extracts threshold voltage information of a driving transistor included in each pixel during a sensing period. In the organic light emitting display, the compensation unit supplies a preset voltage to a gate electrode of the driving transistor so that a second current flows during the sensing period, and supplies a reference voltage to a drain electrode of the driving transistor during the period in which the second current flows.

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.
