Classification: CPC G | IPC G

Claim 16:
17. A display apparatus comprising:
a display panel;
a driving controller configured to generate data signals based on input image data; and
a data driver electrically connected to each of the display panela and the driving controller, configured to use the data signals to generate data voltages, and configured to output the data voltages to the display panel,
wherein the display panel is configured to emit or transmit light using the data voltage to display an image, and
wherein the driving controller is configured to perform a gamma conversion of a first color, a gamma conversion of a second color, and a gamma conversion of a third color for generating the data signals using first color adjustment values, second color adjustment values, and third color adjustment values that are generated based on a first color reference luminance ratio, a second color reference luminance ratio, a third color reference luminance ratio, first color target luminance ratios, second color target luminance ratios, and third color target luminance ratios, which are respectively a ratio of a first color luminance value to a total color luminance value for a reference grayscale value, a ratio of a second color luminance value to the total color luminance value for the reference grayscale value, a ratio of a third color luminance value to the total color luminance value for a reference grayscale value, ratios of first color luminance values to total color luminance values for adjustment target grayscale values, ratios of second color luminance values to the total color luminance values for the adjustment target grayscale values, and ratios of third color luminance values to the total color luminance values for the adjustment target grayscale values.
