Abstract: A display device includes: a visual sensor for generating visual sensing data by sensing an eye of a user; a display panel including a display area and pixels disposed on the display area; an image converter for generating a second image signal by converting a first image signal of the pixels based on the visual sensing data; and a data driver for providing the pixels with data signals corresponding to the second image signal. The image converter generates visual information based on the visual sensing data, determines a first area and a second area different from the first area of the display area based on the visual information, and generates the second image signal by converting grayscales of the second area in the first image signal.

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.
