Abstract: The present disclosure relates to a display device, a gamma correction circuit, and a display driving method that are capable of reducing a level at which a boundary between a normal area and an optical area is perceived by a user by correcting image data based on a gamma curve selected based on an area where a subpixel to which image data is to be supplied is disposed among a first gamma curve for the first driving area, a second gamma curve for the second driving area, and a third gamma curve for the boundary driving area, and outputting corrected image data.

Abstract: A foldable display device may include: a display panel including a first active area, a second active area, and a foldable area between the first active area and the second active area for folding and unfolding the display panel; and a camera in the second active area or overlapping with the second active area. The first active area may be configured to display a test pattern, and the camera may be configured to capture the test pattern to output captured data for compensating a data voltage applied to at least one of the first active area and the second active area of the display panel for displaying an image.
