Shuttered waveguide light field display

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 first waveguide, a set of first shutters spatially distributed in a two-dimensional array across the face of the first waveguide, and a second waveguide, the view image generator optically coupled to the second waveguide, the second waveguide optically coupled to one edge of the first waveguide, the first waveguide optically coupled to each first shutter, the view image generator operable to generate a set of beams of light from one of a set of view images, the second waveguide configured to transmit the set of beams from the view image generator into the first waveguide, the first waveguide configured to transmit the set of beams along its length via internal reflection, each first shutter operable to be switched between a closed state and an open state, the closed state of the first shutter configured to prevent the beams from escaping the first waveguide, the closed state of the first shutter configured to allow the beams to propagate along the first waveguide past the first shutter, the open state of the first shutter configured to allow the beams to escape the first 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 first shutters, thereby to allow the set of beams escaping from the subset of the set of first shutters to correspond to a different one of the set of view images.
