Abstract: A three-dimensional display device incorporating a large number of illumination points located in a regular pattern within a three-dimensional display region is disclosed. The display region is defined by an optically transparent housing, while the illumination points are the exit tips of wave guides such as optical fibers. The fibers are arranged in bundles mounted vertically within the display region, with each bundle consisting of a large number of parallel optical fibers joined together and each fiber terminating in an exit tip at a different location along the longitudinal axis of the bundle. The use of a multiplicity of bundles, each containing fibers arranged in a matrix and having mutually displaced exit tips, produces a large number of illumination points arranged in a three-dimensional lattice within the display region, with each illumination point being definable by its corresponding bundle and its location within that bundle matrix.
