Abstract
A display device according to example embodiments includes: a display panel including a plurality of pixels configured to display an image; a gamma voltage generator configured to generate a plurality of gamma sets respectively corresponding to a plurality of luminance ranges, and configured to compare a target luminance level with the luminance ranges to select a target gamma set among the gamma sets, and to generate a plurality of gamma voltages using the target gamma set, the target luminance level being a luminance level of the image; a first dimming controller configured to scale input image data based on the target luminance level; a second dimming controller configured to determine an off duty ratio of an emission signal based on the target luminance level; and a display panel driver configured to drive the display panel based on the input image data and the gamma voltages.
