ABSTRACT:
A fiber optic panel provides backlighting in devices such as rubber keypads, membrane switches, liquid crystal displays, rigid panels, or the like. The fiber optic panel comprises a light source for emitting light and a fiber optic cable which transmits the light to a plurality of different locations throughout the device. The fiber optic cable comprises a plurality of optical fibers, each of which individually terminates at one of a plurality of different locations to illuminate that location. Alternatively, the optical fibers individually terminate at evenly spaced locations throughout the device to illuminate a region uniformly.
