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.
