Abstract
A Reflective Field Emission Display (FED) system using reflective field emission pixel elements is disclosed. In the FED system disclosed, each pixel elements is composed of at least one edge emitter that is operable to emit electrons and at least one reflector that is operable to first attract and then reflect the emitted electrons onto a transparent layer that is operable to attract the reflected electrons. The transparent anode layer is oppositely positioned with respect to the cathode or emitter edge. In a one aspect of the invention, a phosphor layer interposed between the transparent layer and the pixel element produces a light photon as reflected electrons are attracted to the transparent layer. In another aspect of the invention, a plurality of phosphor layers are applied to the transparent layer to produce a color display when reflected electrons are attracted to the transparent layer.
