[Paper] Floating Autostereoscopic 3D Projection Display with High Light Efficiency and Wide Viewing Depth using Anisotropic Light Diffuser

Abstract

We improved light efficiency and viewing zone depth for high-resolution floating autostereoscopic 3D display based on the iris-plane dividing technology. Newly developed light diffusion film and optical system sent almost all image light to the viewer and realize high light efficiency and uniformity. In addition, stacked liquid crystal optical shutters achieved control of the viewing zone and realized 3D images without crosstalk noise in the real space with wide depth of the viewing zone. Our floating 3D display system allows glassless and provides high-resolution 3D images with no crosstalk between left and right viewing zones. Therefore, this 3D display system is promising for the future high-presence interactive communication systems.
