ABSTRACT:
A backplate structure for a field emission display includes a transparent backplate substrate, a plurality of opaque electrodes, a plurality of field emitters geometrically located in the opaque electrodes, and a focusing electrode. The focusing electrode has an exterior surface with a conductive layer disposed substantially over the exterior surface, and the focusing electrode is electrically isolated from the opaque electrodes. The faceplate structure can further include a plurality of transparent electrodes that are orthogonal to the opaque electrodes.
