Abstract: A method for fabricating row lines and pixel openings of a field emission array that employs only two masks. A first mask is disposed over electrically conductive material and semiconductive material and includes apertures that are alignable between rows of pixels of the field emission array. Row lines of the field emission array are defined through the first mask. A passivation layer is then disposed over at least selected portions of the field emission array. A second mask, including apertures alignable over the pixel regions of the field emission array, is disposed over the passivation layer. The second mask is used in defining openings through the passivation layer and over the pixel regions of the field emission array. Conductive material exposed through the apertures of the second mask may also be removed to expose the underlying semiconductive grid and to further define the pixel openings.

Abstract: A cathode structure comprises a cylindrical metal sleeve having aperture portions at both ends, a base metal having an aperture portion on one end, which is fitted onto one of the aperture portions of the metal sleeve, and an electron-emitting layer, which is formed on a flat portion of an outside surface of the base metal. After an electron-emitting material is sprayed onto the base metal, its surface is mechanically flattened to form the electron-emitting layer. Thus, the planarity of the surface of the electron-emitting layer can be improved without deterioration of the electron emission characteristics and the moirnull can be decreased without reduction of the resolution.

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing treatment of a substrate and then depositing the film. The treatment step creates nucleation and growth sites on the substrate for the film deposition process and promotes election emission of the deposited film. With this process, a patterned emission can be achieved without post-deposition processing of the film. A field emitter device can be manufactured with such a film.

Abstract: An incandescent halogen lamp used in connection with a vehicle headlamp system in which stray light attributable to reflection off of internal lamp components is reduced while the structural integrity of the lamp is maintained. The halogen lamp includes two filaments, several lead wires, and a support bridge all sealed within a glass envelope. Each filament is connected at its outermost end to a flattened end portion of a lead wire which extends along the length of the filament from near the support bridge to the upper end of the filament. The flattened outer ends of the lead wires have a narrow profile that is in alignment with the direction of illumination of light from their respective filaments. This arrangement reduces the surface area that could otherwise interfere with light emitted by the filaments, and thereby reduces the overall stray light produced by the lamp. The flattened outer ends can have a roughened surface to further help reduce the amount of light reflected off the lead wires.
