SPATIAL AND TEMPORAL MULTIPLEXING DISPLAY
First Claim
1. A system comprising, a multi-view display configured to combine spatial multiplexing using a parallax barrier or lenslet, and temporal multiplexing using a directed backlight, to generate a plurality of views by determining which light sources corresponding to a viewing space are illuminated at a particular time.

Abstract
Described is using a combination of which a multi-view display is provided by a combining spatial multiplexing (e.g., using a parallax barrier or lenslet), and temporal multiplexing (e.g., using a directed backlight). A scheduling algorithm generates different views by determining which light sources are illuminated at a particular time. Via the temporal multiplexing, different views may be in the same spatial viewing angle (spatial zone). Two of the views may correspond to two eyes of a person, with different video data sent to each eye to provide an autostereoscopic display for that person. Eye (head) tracking may be used to move the view or views with a person as that person moves.

- 10. A method performed on at least one processor, comprising, determining a first position of a first view and a second position of a second view, determining subsets of light sources of a display that, when illuminated behind a lens, direct light to a spatial viewing angle corresponding to the both the first view and the second view, and in a first time slice, illuminating selected light sources of the subsets to direct collimated light corresponding to first video data to the first view and, in a second time slice, illuminating other selected light sources of the subsets to direct collimated light corresponding to second video data to the second view.
- 17. A system comprising, a head tracking component that provides position data corresponding to each position of a plurality of views, distribution logic that determines from the position data, from a display device'"'"'s spatial capabilities, and from the display device'"'"'s frame rate capabilities, parameters for distributing video frames to each of the views, and a scheduling algorithm that uses the parameters to spatially and temporally multiplex light sources to output renderings of the video frames to the views.
