    Patent number: 6390638
    Abstract: A device for illuminating a flat panel display. The illuminating device has a flat light guide with light input edges and a light output surface, and light sources disposed at the light input edges. A layer of expanded PTFE is wrapped closely around the light sources, conforming to their exterior surface, and is spread across a back surface of the flat light guide. Reflector film layers (white and metallized) are wrapped over the layer of expanded PTFE. Preferably copper tape is then layered over the reflector film layers. Light is emitted from the light output surface when the light sources are energized.
