Abstract: An anode screen for a field-emission-display is formed by layering light-permeable conductive material and phosphor respectively over a transparent substrate. A plurality of holes are formed in the layer of phosphor to expose corresponding regions of the conductive material. In a further embodiment, the anode screen is disposed in spaced and opposing relationship to a cathode emitter plate that comprises a plurality of electron emitters. Pixel regions of the phosphor of the anode screen correspond to regions of the phosphor opposite respective electron emitters of the plurality of electron emitters. Preferably, each pixel region of the phosphor has a number of holes spaced equally about its periphery. In the preferred embodiment, six holes delimit a hexagon shape for their respective pixel region, wherein centers of the holes provide apexes of the hexagon.

The apparatuses each include electron beam uniformity circuitry. The electron beam uniformity circuit provides a grid voltage, VGrid, with a DC offset voltage sufficient to induce field emission from a cathode and a periodic signal superimposed on the DC offset voltage for varying the grid voltage at a frequency fast enough to be undetectable by the human eye. The cathodes may be of the micro-tipped or flat variety. The periodic signal may be sinusoidal with peak-to-peak voltage of between about 5 volts and about 50 volts.

Abstract: A flat panel field emission device includes a black matrix formed from an electrically insulative material such as praseodymium-manganese oxide. The insulative black matrix increases image contrast and reduces power consumption. For field emission devices which utilize a switched anode for selectively activating pixels, the insulative material reduces or eliminates problems associated with short circuiting of the pixels.

Abstract: A black matrix material for increasing resolution and contrast of field emission displays is disclosed. The black matrix material is preferably deposited by electrophoresis in the interstitial regions between phosphor pixels of the faceplate. By this technique, high resolution and/or small surface area field emission displays may be manufactured. The black matrix material does not brown when subjected to the conditions associated with the manufacture of field emission displays, is chemically inert and remains stable under vacuum conditions and electron bombardment. The black matrix material is selected from boron carbide, silicon carbide, tungsten carbide, vanadium carbide and mixtures thereof.

Abstract: A faceplate in a flat panel display has attachment sites made with a method that includes steps of mixing frit and photoresist to form a mixture, applying the mixture to the substrate, softbaking the substrate and mixture, and exposing and developing the resist to define adhesion sites. Spacers are then attached to the faceplate at the adhesion sites.
