Abstract
An optical compensation device includes a measurement part that measures a luminance of a reference point of a display panel displaying an image and a luminance of a neighboring point separated from the reference point to generate measurement data, a camera that photographs a surface of the display panel to generate a photographed image, and a compensation part that generates a scaling value of the neighboring point based on the measurement data of the reference point, a photographed data generated based on the photographed image of the reference point, the measurement data of the neighboring point, and a photographed data generated based on the photographed image of the neighboring point, and generates compensation data of the neighboring point based on the scaling value of the neighboring point and the photographed data of the reference point.
