Abstract: A display device includes a display part, a degradation compensator that generates a first compensated grayscale value by compensating for a first grayscale value corresponding to a first pixel, and generates a second compensated grayscale value by compensating for a second grayscale value corresponding to a second pixel, and a data driver that generates a first data signal based on the first compensated grayscale value to supply the first data signal to the first pixel, and generates a second data signal based on the second compensated grayscale value to supply the second data signal to the second pixel. A second degradation curve is defined by a first degradation coefficient corresponding to a first degradation curve, and a second degradation coefficient corresponding to a first estimated degradation curve for the light conversion particles of a second color calculated by applying the first degradation curve.

Abstract: An optical compensation device includes a luminance measurer that measures display luminance of a display device including a plurality of areas. A gamma corrector corrects a gamma voltage so that a first area of the plurality of areas has a gamma characteristic corresponding to a target gamma value based on the display luminance, and calculates a gamma value for each of the plurality of areas based on the display luminance. An optical compensator calculates a compensation parameter for each grayscale based on the display luminance and the gamma value. A luminance deviation for each of plurality of areas of the display device is compensated based on the compensation parameter.
