Abstract:
1. A reflective admission pixel element comprising: a substrate layer; at least one reflector layer; at least one pixel memory cell; at least one emitter layer, electrically isolated and positioned above a corresponding one of said at least one reflective layer, said at least one emitter layer circumjacent said at least one reflector layer; at least one thin-film transistor circuit (TFT) applying a first potential to said at least one reflector layer, said first potential being stored in a corresponding one of said pixel memory cell, said first potential determining a color level of said pixel, 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 opposed to said corresponding one of said at least one reflector layer; and wherein said at least one emitter layer comprises a plurality of nanostructures.
