Abstract
Light emitting elements in an illumination unit of a display may be blanked during updates of pixels of a spatial light modulator (SLM). Updates of pixels in different segments of the SLM may be coordinated with blanking of corresponding segments of the illumination unit. Updating of segments of a light source (30A-30D) may be coordinated so that not all segments are updated in each frame (34A-37D) of a video.
