Abstract
This invention is a device for displaying three-dimensional images using an array of tilting microcolumns. It can create high-resolution, large-scale, moving, three-dimensional images that can be viewed by people in different locations, with full parallax, without special eyewear. Unlike currently available methods, this invention: does not require special eyewear, works for multiple viewers, provides parallax in all directions, does not have a very restrictive viewing zone, does not produce only transparent images, does not require coherent light, is scalable to large displays, does not require liquid movement to adjust lens shape, and does not require complex systems to individually control large numbers of lenses.
