FIBER OPTIC DISPLAY SCREEN

摘要

A fiber optic based display system includes a plurality of optic fibers having an image receiving end and an image display end. The image receiving ends are bundled together and receive a graphic image from a projector. Each optic fiber transmits a piece of the image to its image display end, which is mounted in a display screen. The image display ends are spaced apart and are visible from a front side of the display screen, from which each fiber projects a light signal corresponding to the piece of the image incident on the image receiving end of the that fiber. The spacing between the image display ends is selected such that a typical person cannot resolve the light signal emitted from adjacent fibers. A person viewing the display screen consequently sees a cohesive image corresponding to the graphic image. The projector may be any type of light projector, including a slide or movie projector or a computer controlled projector which individually projects each pixel sequentially into the image receiving ends. In a second embodiment, each optic fiber is split into four optic fibers to reduce the spacing between adjacent image display end in the display screen. Both of these embodiments may be used with a plurality of lenses configured to collimate the light signals transmitted from the display screen to increase the intensity of the projected image. In another embodiment, the display screen is actually formed integrally with a piece of carpet to provide a floor display.
