ABSTRACT:
A method and system for creating very thin displays producing virtual images based on extremely small "pinpoint" light sources. In an embodiment, a pinpoint light source is used in a manner analogous to a pinhole lens to magnify and view a displayed image up close. In another embodiment, an array of pinpoint light sources with or without intervening lenses is used to illuminate a spatial light modulator to produce an extremely thin virtual image display.
