Abstract: A display device and an optical compensation method for the same are disclosed. In one aspect, the method includes displaying a test image on the display panel, wherein the display panel comprises first, second, and third areas. The method also includes photographing the first and second areas together to generate first photographed data, photographing the second and third areas together to generate second photographed data, and extracting luminance data from each of the first and second photographed data. The method further includes respectively applying different weights to the luminance data of the second area extracted from each of the first and second photographed data to generate compensated luminance data, and generating a compensation parameter for each pixel based at least in part on the compensated luminance data.
