Abstract
A multiview backlight, multiview display, and method of multiview backlight operation include reflective multibeam elements configured to provide emitted light having directional light beams with directions corresponding to view directions of a multiview image. The multiview backlight includes a light guide configured to guide light and an array of the reflective multibeam elements. Each reflective multibeam element includes a plurality of reflective sub-elements and is configured to reflectively scatter out a portion of the guided light as the emitted light. The multiview display includes the multiview backlight and an array of light valves to modulate the directional light beams to provide the multiview image. Each reflective sub-element protrudes from a guiding surface of the light guide by a respective protrusion distance. At least some of the protrusion distances can vary as a function of distance along a length of the light guide.
