Abstract
A luminance compensating apparatus includes: a color coordinate data receiver; a white luminance data receiver; a luminance divider to divide a first luminance of a first display module from first color coordinate data and first white luminance data, and to divide a second luminance of a second display module from second color coordinate data and second white luminance data; a luminance rate calculator to calculate a rate of the second luminance compared to the first luminance to output a first luminance rate; a target luminance calculator to divide the second luminance by the first luminance rate to output a first target luminance of the second display module; and a luminance compensator to output first luminance compensating data for compensating the second luminance of the second display module from the first target luminance.
