Patent attributes
A light field display device comprising at least one multiplexed light field display module, the multiplexed light field display module comprising a view image generator, a waveguide, and a set of shutters spatially distributed along the waveguide, the view image generator optically coupled to the waveguide, the waveguide optically coupled to each shutter, the view image generator operable to generate a set of beams of light from one of a set of view images, the waveguide configured to transmit the set of beams along its length via internal reflection, each shutter operable to be switched between a closed state and an open state, the closed state of the shutter configured to prevent the beams from escaping the waveguide, the open state of the shutter configured to allow the beams to escape the waveguide, the module operable to generate, over time, the set of beams from a different one of the set of view images, and to open, over time, a different subset of the set of shutters, thereby to allow the set of beams escaping from the subset to correspond to a different one of the set of view images.
