Abstract
An optical compensation device includes an optical measurer which measures a first transmission luminance of a transmission area of a display device when a light source of an optical sensor, which overlaps the transmission area, does not emit light, a second transmission luminance of the transmission area when the light source emits light, and a neighboring (adjacent) luminance of a neighboring (adjacent) area neighboring the transmission area, and a gamma determiner which determines a first transmission reference gamma voltage for the transmission area so that a difference between the first transmission luminance and the neighboring (adjacent) luminance is within a reference range, and determines a second transmission reference gamma voltage for the transmission area so that a difference between the second transmission luminance and the neighboring (adjacent) luminance is within the reference range.
