Abstract
A light emitting panel and method of making same including an emitter surface having one or more layers of woven fiber optic material with disruptions or bends as discrete locations along the length of the fibers to allow light to be emitted therefrom and which are coated to change the attenuation of the fibers to increase the amount of light emitted therefrom. The panel is particularly suitable for use as a back light for a liquid crystal or other device, the light being transmitted to the emitter surface from a remote light source through a cable or light pipe connected to one or both ends of the emitter surface.
