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