Abstract: A display device includes: a display panel including a plurality of pixels connected to a plurality of scan lines; a scan driving circuit, which drives the plurality of scan lines in synchronization with a clock signal; and a driving controller, which outputs the clock signal. While an operating mode is a multi-frequency mode, the driving controller comparts the display panel into a first display area and a second display area. A hold frame of the multi-frequency mode includes a first section during which the first display area is driven, and a second section during which the second display area is driven. The driving controller outputs the clock signal of a normal power mode during the first section and outputs the clock signal of a low-power mode during the second section.

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.
