Abstract
Provided is a color adjustment method for a display apparatus. The color adjustment method includes: measuring first luminance coordinate data indicating a luminance and color coordinates of a color displayed on a display device when image data corresponding to a white point is supplied to a drive circuitry; measuring second luminance coordinate data indicating luminances and color coordinates of colors displayed on the display device when image data corresponding to the white color of intermediate grayscale values are supplied to the drive circuitry; measuring third luminance coordinate data indicating a luminance and color coordinates of a color displayed on the display device for each of R, G and B elementary color points when image data corresponding to each of the R, G and B elementary color points is supplied to the drive circuitry; and calculating correction parameters based on the first to third luminance coordinate data.
