Abstract
A display system includes a rendering device and a display device. The rendering device is to render a sequence of frames for display at a frame rate and to set an illumination configuration to be applied by the display device during a frame period for each frame of the sequence of frames based on the frame rate. The illumination configuration controls at least one of an illumination level and a duration for an illumination strobe, and at least one of an illumination level for an illumination fill preceding the illumination strobe in the frame period and an illumination level for an illumination fill following the illumination strobe in the frame period. The display device is to receive a representation of the illumination configuration from the rendering device and apply the illumination configuration during a frame period for each frame of the sequence of frames to display the frame.
