ABSTRACT:
A projected image displaying apparatus for displaying bright three-dimensional images on a display screen. In one embodiment, images in three colors, each in the form of vertically oriented stripes, are projected onto a transmissive diffusion surface with the stripes of the three images interleaved with one another, and preferably slightly overlapping one another. A lenticular lens may be employed to direct the three dimensional image to the eyes of the viewer. In another embodiment, the two-dimensional images are projected in a form of three energy beams, which may be infrared, ultraviolet or visible light, onto a light-emitting layer composed of repeating sequences of first through third phosphor stripes, each corresponding to one of the primary colors.
