Abstract
Abstract An illuminated display which utilizes optical fibers to convey visible light from a singular light source to a display board. The display board is provided with channels (apertures) into which ends of optical fibers are inserted and secured. The placement of optical fibers at regular intervals around the perimeter of an alphabetical character and an irregular, random locations within the area defined by the perimeter produces a display with enhanced visual effects, greater reliability, and lower operating costs than conventional illuminated displays.
