Abstract
A time-multiplexed multiview backlight, display, and method of time-multiplexed multiview backlight operation provide one or both of enhanced spatial resolution and enhanced angular resolution using time-multiplexing. The time-multiplexed multiview backlight includes a light guide configured to guide light as time-multiplexed guided light having different directions during different time intervals and an array of multibeam elements configured to scatter the time-multiplexed guided light as directional light beams. A first set of multibeam elements is configured to selectively scatter out the time-multiplexed guided light having the first direction and a second set of multibeam elements of the multibeam element array is configured to selectively scatter out the time-multiplexed guided light having the second direction. The time-multiplexed multiview display further includes an array of light valves configured to modulate the directional light beams as view pixels of a multiview image having different views in the different view directions.
