Patent Images
1. A display for displaying a sequence of frames of image data, the display comprising:
- a light source comprising a plurality of light source segments, each light source segment comprising a plurality of individually-controllable light emitters;
a spatial light modulator comprising a plurality of SLM segments, each SLM segment comprising a plurality of individually-controllable elements and corresponding to one or more light source segments containing one or more light emitters physically arranged to contribute to illumination of at least one of the plurality of individually-controllable elements of the SLM segment;
wherein the SLM segments are physically arranged in a first sequence beginning with a SLM segment including a top left corner of the display and ending with a SLM segment including a bottom right corner of the display; and
a controller configured to update at least some of the SLM segments according to image data in a second sequence different from the first sequence.

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.
