Abstract
A display system includes a display device having a plurality of individually-controllable illumination regions and a rendering device. The rendering device is to render a frame for display at the display device during a frame period, to determine a motion estimate representation for each region of a plurality of regions of the frame, each region of the frame corresponding to an illumination region of the display device, and to set, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period or a subsequent frame period based on the motion estimate representation for the corresponding region of the frame.
