Abstract: An electrode structure for a display that includes lower electrodes and upper electrodes. In one embodiment, lower and upper electrodes are formed of either an aluminum alloy or a silver alloy. In another embodiment, upper and lower electrodes are formed using a metal alloy layer over which a cladding layer is deposited.

Abstract: An apparatus and method for regulating the emission current from a single (macroscopic) field emitter, from groups of emitters within a large (microscopic) array, or from each cell within an array is described. The apparatus includes an additional aperture, fabricated at each field emitter array cell, to create and electron energy filter. The filter aperture of the electron energy filter is similar to the gate aperture but located above or in front of the gate aperture, and is held at a positive potential lower than the gate. The filter allows only those electrons with energy greater than some minimum (the cutoff energy) to pass through. A current-limiting circuit is placed in series with the gate aperture, limiting the total current of electrons that do not pass through the filter. Thus, emission from low energy states is limited without limiting emission from states near the Fermi level.

Abstract: A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.

Abstract: High lumen output quartz metal halide lamps are provided which comprise a vacuum outer fill, and a silicon nitride CVD coating on the outside of the quartz arc tubes (discharge tubes). Instead of nitrogen filled outers, vacuum lamp outers are used to reduce energy loss (since heat conduction loss is reduced) and to increase lumen output. Additionally, only the outside of the arc tubes is coated with silicon nitride, without coating the metal components. This reduces or blocks sodium diffusion through the quartz walls. The silicon nitride coating also retards migration of the trace hydrogen from the lamp outer into the arc tube. At least about a 10% increase, and preferably a 15% increase in lumen output is realized by using a vacuum lamp outer instead of the nitrogen fill outer conventionally used for the traditional quartz fill lamps. The heat conduction loss is reduced and the lamp efficiency is increased significantly.
