    Abstract: A system may include a processor, a graphics controller, and a display. The graphics controller may generate video data to be presented on the display. The display may include a display panel, a backlight unit for providing the display panel with backlight, and a display timing controller for communicating with the graphics controller. The display may be used in non-movie mode and movie mode. The backlight unit may be operated in fixed backlight mode during the non-movie display mode and may be operated in dynamic pixel backlight (DPB) mode during the movie display mode. Backlight level adjustments may be sloped only during the non-movie mode. Backlight level sloping can be handled internally within the backlight unit, can be controlled using pulse width modulation with the display timing controller, and implemented using incremental backlight level adjustments with the processor.
