    Abstract: A display device includes a first gain provider which controls a first gain value during a first display period in which a still image is displayed, a second gain provider which controls a second gain value during a second display period in which a moving image including a still area is displayed, and a grayscale converter which applies the first gain value or the second gain value to an input image and generates an output image. The first gain provider linearly or exponentially increases the first gain value to a maximum gain value based on a load of the still image from a first time point when the second display period changes to the first display period to a second time point at which the first gain value starts to decrease from the maximum gain value.
