1. An organic light emitting display device, comprising:

  • a display panel including a plurality of pixels and a plurality of sensing lines respectively coupled to the pixels, each of the pixels including an organic light emitting device and a driving transistor to control a current flow in the organic light emitting device; and

    a panel driver configured;

    to receive an input image data for at least one of the pixels,to generate a sensing data by sensing a characteristic variation of the driving transistor in the at least one of the pixels through a corresponding one of the sensing lines,to calculate a frame representative value by analyzing the input image data in a unit of one frame,to generate a peak luminance data to limit peak luminance of an input image based on the frame representative value,to generate a corrected data for the at least one of the pixels 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, andto supply the data voltage to the at least one of the pixels.
