Abstract
A method of operating a display apparatus includes the following steps: calculating a first color reference luminance ratio, a second color reference luminance ratio, and a third color reference luminance ratio for a reference grayscale value; calculating first color target luminance ratios, second color target luminance ratios, and third color target luminance ratios for adjustment target grayscale values; generating first adjustment values, second adjustment values, and third adjustment values based on the first, second, and third color reference luminance ratios and the first, second, and third color target luminance ratios; performing gamma conversions of first, second and third colors using the first, second, and third adjustment values for the adjustment target grayscale values; using results of the gamma conversions to generate data voltages; and using the data voltage and a display panel of the display apparatus to emit or transmit light for displaying an image.
