3D display system with rear projection screens formed of water mist or spray

摘要

A 3D display system using a planar sheet of mist or water droplets as a rear projection screen. The system includes a screen generation assembly with a nozzle configured to convert supply water into a screen of water droplets. The screen is substantially planar and has a front surface facing a viewing area and an opposite rear surface. The display system includes a projection assembly projecting 3D content onto the rear surface. The projection assembly includes a first projector projecting left eye images and a second projector projecting right eye images. The 3D content may be provided using polarization or other 3D technology. For example, the first projector includes a first interference filter and the second projector includes a second interference filter differing from the first interference filter, whereby the left and right eye images are presented concurrently on the rear surface with differing bands of the visible color spectrum.
