Abstract
A field emission display device includes a baseplate having a set of field-induced electron emitters for each pixel in a display. Each set includes a plurality of emitters each carried by a supporting substrate and disposed within a respective aperture in an insulating layer deposited on the surface of the substrate. A conductive layer is deposited on the insulating layer peripherally about the apertures. A plurality of emitter conductors are each operatively coupled to the emitters of one of the sets of emitters. A conductive voltage applied to the conductive layer and a source voltage applied to one of the emitter conductors causes the emitters coupled to the emitter conductor to each emit an electron emission. The display device also includes a faceplate having a transparent viewing layer positioned in a parallel spaced-apart relationship with the baseplate. An anode is deposited on a planar surface of the viewing layer opposite the sets of emitters. A luminescent layer has a plurality of localized portions each deposited on the anode opposite one of the sets of emitters so that an anode voltage applied to the anode will direct any electron emissions from the emitters toward the…
