Abstract

A horizontal parallax multiview display employs a plurality of slanted multibeam columns to scatter out of a light guide a plurality of directional light beams having principal angular directions corresponding to different view directions of the horizontal parallax multiview display. The plurality of directional light beams is modulated using an array of light valves to provide a multiview image having horizontal parallax. Further, the horizontal parallax multiview display employs a light control film having a slanted light control axis aligned with slanted multibeam columns of the slanted multibeam column plurality. The light control film is configured to control a view angle of the multiview image in a direction orthogonal to the horizontal parallax. The slanted multibeam columns may provide the multiview displays with a balanced resolution.
