Abstract: A method of compensating a display device includes: displaying a first display image of a calibration pattern; generating a first photograph image of the calibration pattern by capturing the first display image; generating a measurement representative position data corresponding to the calibration pattern by measuring the first photograph image; generating a third-order fitting representative position data by performing a two-dimensional third-order fitting; displaying a second display image of a full white display; generating a second photograph image of the full white display by capturing the second display image; generating a first crop image by performing a size adjustment based on the third-order fitting representative position data; calculating a luminance compensation value by comparing a measured luminance of the first crop image with a target luminance; and generating a compensated image data by applying the luminance compensation value to an image data.
