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.

A light emitting panel comprising an emitter surface having a plurality of optical fibers extending from one end of said emitter surface toward another end thereof, said optical fibers having a plurality of disruptions or bends along the length of said optical fibers which cause light entering such optical fibers at said one end to be emitted from said disruptions or bends, said disruptions or bends being formed to cause the light output from said disruptions or bends to progressively increase with the distance from said one end for at least a portion of the length of said emitter surface, and coating means applied to said optical fibers in said portion of said emitter surface having a higher index of refraction than said optical fibers to increase the attenuation of light emitted from said portion of said emitter surface and produce a substantially uniform light output from said portion of said emitter surface.
