Abstract
A programmed illuminated display is provided. The display includes a panel having a plurality of apertures extending therethrough. An optical fiber is provided for each aperture. Each optical fiber has an emitting end aligned with the front face of the panel and a receiving end extending beyond the rear face of the panel. The optical fibers are grouped in a selected manner, and each group of the optical fibers is connected to an LED. The LED's are connected to a control circuit that includes a programmable chip. The chip is programmed to generate a selected firing order for the LED's which in turn direct light through the associated optical fibers for providing a programmed illumination for the display.
