Parallax barrier 3D reflection display using polarizer slit

Abstract

The 3D projection display system using an LCD projector has superior characteristics, such as having a large screen with wide field of view. However, a conventional system has such demerits as viewing stereoscopic images with special glasses. We describe transmission and reflection 3D displays using a polarizer slit barrier. These 3D displays can avoid the problem of conventional system and thus the observer can view glasses-free 3D images.
