Abstract
A display system includes a rendering device and a display device having a plurality of individually-controllable illumination regions. The rendering device is to render a frame for display at the display device during a frame period and to determine a brightness 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. The rendering device further is 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 and a subsequent frame period based on the brightness representation for the corresponding region of the frame, wherein the illumination configuration controls at least one of an illumination level, a duration, and a position of an illumination strobe to be implemented for the corresponding illumination region.
