Abstract
An organic light emitting display device comprising a display panel and a panel driver is disclosed. The display panel includes pixels and sensing lines respectively coupled to the pixels. Each pixel includes an organic light emitting device and a driving transistor to control a current flow in the organic light emitting device. The panel driver is configured to receive an input image data, to generate a sensing data by sensing a characteristic variation of the driving transistor, to generate a peak luminance data to limit peak luminance of an input image, to generate a corrected data by correcting the input image data based on the sensing data, to convert the corrected data to a data voltage based on a plurality of reference gamma voltages set based on the peak luminance data, and to supply the data voltage to the pixels.
