Abstract: A display device includes a display panel, a display driver, and a timing controller. The data driver may apply a first data voltage set and subsequently a second data voltage set to the display panel during a screen saver operation of the display device. The first data voltage set may cause the display panel to display a first illuminated area. The second data voltage set may cause the display panel to display a second illuminated area. The timing controller may supply image data to the data driver for the second data voltage set to cause the second illuminated area to have a luminance level. The timing controller may determine a value for controlling the luminance level based on a distance between a position of the first illuminated area and a position of the second illuminated area.

Abstract: A liquid crystal display device is provided as follows. A display panel having a first aspect ratio includes pixels, scan lines and data lines. The pixels are arranged at intersections of the scanning lines and the data lines. A display panel driver, in a partial mode in which an image having a second aspect ratio different from the first aspect ratio is displayed on a partial region of the display panel for two or more frame periods, supplies scan signals only to a first number of scan lines electrically connected to pixels of the partial region for a first type frame period of the two or more frame periods, and supplies scan signals to the plurality of scan lines for a second type frame period of the two or more frame periods.
