Abstract
Aspects of the present invention involve novel three-dimensional display systems. Multi-view-window-based display systems are used to generate floating three-dimensional displays. In embodiments, an optical focusing element is positioned at a distance that is greater than or equal to the focal length of the optical focusing element from the viewing windows to form projected viewing windows through which a user can see a floating 3D image. In alternative embodiments, an optical focusing element is positioned at a distance that is less than the focal length of the optical focusing element from the viewing windows to form a rear-projection-like three-dimensional display system. In embodiments, a retro-reflective light diffusion screen is used in the multi-view-window-based display systems.
