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.
