Abstract: A display device includes: a display panel, which displays an image; a driving controller, which determines a gain reduction region based on input image data input to the display panel, and generates a data signal by correcting the input image data by applying a gain to the input image data to correspond to the gain reduction region; and a data driver, which converts the data signal into a data voltage to output the data voltage to the display panel. The driving controller is configured to generate first, second, and third data signals by correcting first, second, and third input image data input to first, second, and third regions of the display panel by applying first, second, and third gain values to the first, second, and third input image data, respectively.

Abstract: A display device includes a display panel and a display image shift controller. The display panel includes a display area in which a display image is displayed and a shift area located within the display area. The display image shift controller generates a route shift signal, where a reference point of the display image is shifted in the shift area based on the route shift signal. The route shift signal includes first and second routes corresponding to a path through which the reference point of the display image is shifted. The first route includes a first sub-route and a second sub-route. The second route includes a third sub-route and a fourth sub-route. The first, second, third, and fourth sub-routes are different from each other.
