<p>The present invention is to provide an organic light emitting display device which can reduce consumption power while maintaining peak luminance of an image and can increase the lifespan. The organic light emitting display device according to the present invention comprises a display panel including a plurality of pixels having a pixel circuit including an organic light emitting device formed in a pixel area defined by a plurality of gate lines, a plurality of data lines, and a plurality of driving voltage lines, and emitting light by current, and a drive transistor controlling the current flowing to the organic light emitting device from the driving voltage lines based on data voltage supplied to the data lines; and a panel driving unit converting frame input data into the data voltage and supplying the converted data voltage to each of the pixels, calculating a peak brightness value and a maximum grayscale value by analyzing the frame input data, and changing driving voltage supplied to the driving voltage lines based on the peak brightness value and the maximum grayscale value.</p> |
