Abstract:
1. An organic light emitting display device, comprising: a scan driver for supplying scan signals to a plurality of scan lines during subframes of a frame; a data driver for generating image data signals utilizing second data and a dummy data signal utilizing dummy data; a plurality of pixels in an active region of the organic light emitting display device configured to emit light in accordance with the image data signals; a dummy pixel in a dummy region of the organic light emitting display device configured to emit light in accordance with the dummy data signal; a degradation compensator for adjusting a bit value of the dummy data to maintain a substantially constant brightness of the dummy pixel by adjusting a light emitting period of the frame for the dummy pixel, and for storing the adjusted bit value; and a timing controller for summing first data for each of the plurality of pixels to generate integrated data, and for generating the second data by adjusting the first data in accordance with the adjusted bit value and the integrated data; wherein the degradation compensator comprises:
