Abstract: A degradation compensation device and an organic light emitting display device including the same are provided. The degradation compensation device includes a degradation rate acquisition unit acquiring estimated degradation rates, estimated with respect to a plurality of respective pixels, based on panel usage information, a digital compensation unit performing digital compensation to lower a digital gradation of each pixel, based on a luminance of a pixel having a maximum degradation rate, among the estimated degradation rates, and an analog compensation unit performing analog compensation to increase luminance of the plurality of pixels by changing an analog voltage supplied to a panel, after performing the digital compensation.
