Abstract

An LED projection light device includes an image forming assembly including a display and a projection assembly for generating and projecting three-dimensional images. The image forming and/or projection assembly may include a lenticular lens, slanted lenticular lens, switchable lenticular film, lenticular screen, parallax barrier The display may be controlled by a volumetric, multiplexed-2D to 3D, or parallax barrier technique, a single image splitter, a double image splitter, a spatial-multiplexer, time division multiplexer, or a tracking-based technique, and may include a 2D/3D switchable display, multiplanar display, ferroelectric LC display, cholestreric LC display, bi-stable nematic LC display, electrochromic films, OLED screen, OEL screen, reflective MEMS display, microcup electrophoretic display, or E-Ink display technical.
