Abstract: An organic light emitting display includes a data driver supplying a sensing data voltage in a sensing mode to prevent degradation of image quality occurring due to a kick-back phenomenon. Each pixel of a display panel of the organic light emitting display has its driving characteristic sensed in the sensing mode. The data driver is configured to supply a high driving voltage, which is higher than the supplied sensing data voltage, and both voltages are successively applied to a data line of the display panel in the sensing mode.
