Abstract:
1. A degradation compensation unit comprising: a first operation unit for receiving downscaled gray data of each pixel for one frame at set intervals and for calculating a degradation time of each pixel corresponding to the downscaled gray data; an accumulation operation unit for receiving the degradation time of each pixel from the first operation unit and for calculating an accumulated degradation time of each pixel by accumulating the degradation time of each pixel; a weight calculation unit for receiving the accumulated degradation time of each pixel from the accumulation operation unit and for calculating a degradation compensation weight for each pixel based on the accumulated degradation time of each pixel; and a second operation unit for receiving the degradation compensation weight for each pixel, for producing compensated gray data for each pixel corresponding to the degradation compensation weight for each pixel, and for providing the compensated gray data for each pixel to a data driver.
