Abstract:
The invention is a novel, modular electro-optic video display (1) assembled from inexpensive tiles (2) made from thermoplastic and composite material that are, therefore, durable and able to withstand the abuses of an interactive environment. The tiles (2) employ a plurality of either thermoplastic optical fibers (26) or solid plastic lightguides to convey projected images from a first, or projection surface, to a second, or display surface where the image appears enlarged. The first surfaces are either micro-displays (9) that correspond in an ordered manner with the modular tiles (2) of the second surface, or one or more projection devices which convey information to the second surface through a plurality of ordered optical fiber bundles (26) or light guides. In addition to these imaging fibers or lightguides, each modular tile comprising the second (display) surface is populated with supplementary optical fibers or lightguides which detect electromagnetic energy.
Abstract:
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.
Abstract:
A fiber optic display sign for outdoor use includes a number of fiber optics (14) having light receiving ends (16) for receiving an image from image generator (15). An array of lenses which may be fixed or movable is positioned adjacent the output ends (16) for directing light to control the viewing angle of the image displayed. The image generator (15) employs a light source (66) formed of a densely packed array of white light emitting diodes and a number of image bearing transparencies (54) mounted on a movable support to position a selected transparency between the light source (66) and the light receiving ends (16). The viewing angle and/or the image displayed is automatically controlled and/or remotely controlled.
