1. An organic light emitting display device, comprising:

  • a pixel unit including scan lines to transfer scan signals, data lines to transfer data signals, and pixels to represent image data, coupled to the scan lines and the data lines;

    a light sensor to generate light sensing signals corresponding to an external light intensity of an environment of the display device;

    an image judging unit to generate image judging signals, according to whether the data signals relate to moving images or still images;

    a signal processor to compare the light sensing signals with reference values to generate selection signals, and to modify the image data according to the selection signals;

    a frame memory to store the image data output from the signal processor;

    a reset signal driver to generate reset signals to reset the frame memory, according to the image judging signals and the selection signals;

    a scan driver to generate the scan signals, and to sequentially output the scan signals to the scan lines; and

    a data driver to generate the data signals, and to output the data signals to the data lines.
