15.2: <i>Distinguished Paper</i> : LC GRIN Lens Mode with Wide Viewing Angle for Rotatable 2D/3D Tablet

Abstract

Abstract To widen the vertical and horizontal angular ranges where the lens performs well, the off‐axis performance of an LC GRIN lens is analyzed, and the detailed conditions of structure are established. We have developed a rotatable 2D/3D display whose 3D viewing azimuth angle is over 30 degrees in both landscape and portrait orientations.
