Abstract: A directional waveguide-based pixel for use in a mutliview display screen is disclosed. The directional waveguide-based pixel has a liquid crystal layer interposed between the waveguide layer and a substrate layer. The waveguide layer has a waveguide and a patterned grating to scatter an input light beam into a plurality of directional light beams, each directional light beam having a direction and angular spread controlled by characteristics of the patterned grating. An active matrix with individually addressable electrodes may be integrated in the substrate layer or in the waveguide layer to modulate the directional light beams.
