Abstract
A display device includes a display panel, a dimming controller, and a panel driver. The display panel includes a plurality of pixels. The dimming controller generates at least one temporary voltage set by performing a first interpolating operation using a (j)th band voltage set and a (j+1)th band voltage set among first through (i)th band voltage sets corresponding to first through (i)th dimming bands, respectively, and generates a grayscale gamma voltage set corresponding to target luminance by performing a second interpolating operation using the temporary voltage set and the (j)th band voltage set. The panel driver drives the display panel by converting image data into a data signal based on the grayscale gamma voltage set and by providing the data signal to the pixels.
