A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a square (or near square) grid, and the lenses also repeat in a square (or near square) grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimension space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

Three-dimensional (3D) electronic displays provide different 3D views and employ one or both of an array of multibeam diffraction gratings arranged in offset rows and light valves having color filters. The displays include a plate light guide configured to guide light beams at a non-zero propagation angle, a multibeam diffraction grating configured to couple out a portion of the guided light beams as a plurality of light beams having different principal angular directions representing the different 3D views, and light valves configured to modulate the differently directed, coupled-out light beams. The multibeam diffraction grating may be a member of the array arranged in offset rows and the display may further include light valves having color filters. Alternately, the light valves include color filters and the display may further include the array of multibeam diffraction gratings arranged in offset rows.

A direct projection light field display comprising an array of projectors for direct projection of a light field. The overall design and incorporation of additional optics achieve the optimal light distribution and small pixel size to produce a high definition, 3D display. The architecture of the direct projection light field display has low a brightness requirement for each projector, resulting in an increased projector density, decreased system, and a decreased power requirement, while producing a high-definition light field.
