Abstract
A transparent display device includes a screen that has a plurality of light deflecting elements that are separated by transparent areas, and a projector device. The projector device is configured to direct light onto the light deflecting elements and not onto the transparent areas. The display device may include a first screen and a second screen separated longitudinally relative to the projector, wherein each screen respectively has a plurality of light deflecting elements. The projector is configured to direct light onto the light deflecting elements and not onto the transparent areas of the two screens such that light from the first and second light deflecting elements appear in different virtual depth planes. Alternatively, a single screen may have first and second pluralities of light deflecting elements of different optical powers, such that light from the first and second light deflecting elements appear in different virtual depth planes.
