    Abstract: The invention includes field emitters, field emission displays (FEDs), monitors, computer systems and methods employing the same for providing uniform electron beams from cathodes of FED devices. 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: High resolution color displays for field emission displays are formed by applying a grille to a screen layer, the grille having a set of holes formed therein exposing areas of the screen layer. A layer of photoresist is applied to the grille and the exposed areas of the screen layer, whereby a plurality of photoresist-covered screen layer areas are defined. One set of the plurality of photoresist-covered screen layer areas is fixed, whereby a fixed set and an unfixed set are defined. The photoresist is removed from the unfixed set and a light emitting substance is deposited on the exposed screen layer area. The fixed set of photoresist is plasma etched.

    Abstract: A process for operating a field emission display (FED) is disclosed. The FED has a faceplate and a baseplate, and a layer of praseodymium-manganese oxide disposed between the faceplate and baseplate. The layer absorbs photons during operation of the FED, and thus provides for improved performance of the FED because, for example, stray photons do not impact the underlying circuitry of the FED.

    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: The object to be coated is exposed to a controlled rate of dispensing of liquid coating material and the rate of movement of the object is controlled with respect to the dispensing so that it is possible to control the coating thickness and rate of deposit with negligible damage to objects projecting from the surface of the object to be coated. Thus, it is possible to control production speed required to achieve the desired coating thickness with a meniscus coating system.
