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.
