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 device includes a substrate, a display panel including a first display area, a second display area, and a third display area between the first and second display areas, each of the first, second, and third display areas including a plurality of pixels, and a sensor which is between the substrate and the first display area of the display panel and senses an external object through the first display area. A first pixel density of the first display area is less than a second pixel density of the second display area, and a pixel density of the third display area varies with relative distances from the first display area.
