Abstract:
A reflective emission pixel element comprising:a substrate layer; at least one reflector layer; at least one emitter layer, electrically isolated and positioned above a corresponding one of said at least one reflector layer, said at least one emitter layer to circumjacent said at least one reflector layer; means for applying a first potential to said at least one reflector layer, wherein a potential difference between said at least one emitter layer and said corresponding one of said at least one reflector layer is operable to draw electrons from said at least one emitter layer to said corresponding one of said reflector layer; a transparent layer oppositely positioned a predetermined distance from said at least one emitter layer, said transparent layer having a conductive layer deposited thereon; means for applying a second potential to said conductive layer to attract electrons reflected from said at least one reflective layer; at least one phosphor layer on said conductive layer oppositely opposed to said corresponding one of said at least one reflector layer.
