A display device may include a display panel that includes a first region and a second region. The display device may include a controller that may receive a first gamma value and a second gamma value, use the first gamma value or a third gamma value to generate first image data, use the first gamma value and the second gamma value to generate a fourth gamma value, and use the fourth gamma value to generate second image data. The display device may include a data driver that may use the first image data and the second image data to generate a first data voltage set and a second data voltage set. The first region may use the first data voltage set to display a first portion of an image. The second region may use the second data voltage set to display a second portion of the image.
