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

Abstract

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.

Description

technical field [0001] This specification relates generally to visual display and projection systems, and more particularly to methods and systems for providing three-dimensional (3D) still or video images in indoor entertainment environments or outdoor entertainment environments, such as amusement parks, sports fields, commercial streets, etc. A location for a large audience. Background technique [0002] There is a growing need to provide entertainment in outdoor environments such as large urban parks, amusement or theme parks, sporting events, outdoor concerts or other settings where large crowds gather. For example, it is known to provide laser or light-based projections as part of outdoor concerts. Among other things, it is popular to provide fireworks displays to entertain the public in a park setting or during or after a baseball, football, or football game. [0003] In many cases, it is often desired that the show being presented is so unique and exciting that peop...

Problems solved by technology

Unfortunately, it is often impossible to produce a high-quality display because such water-based displays often require tightly controlled environments with little or no wind, very low ambient light or dark backgrounds, and high-brightness projectors
