Abstract
A display apparatus includes a display panel, a voltage compensator, and a data driver. The display panel is configured to display an image. The voltage compensator is configured to compensate a plurality of normal grayscale gamma voltages corresponding to a plurality of grayscale values equal to or greater than a reference voltage based on a plurality of measured luminances for the plurality of the grayscale values, and to determine a low grayscale gamma voltage less than the reference voltage based on the measured luminances. The data driver is configured to generate a data voltage based on the normal grayscale gamma voltage and the low grayscale gamma voltage and to output the data voltage to the display panel.
