Abstract: A multiple beam cathode ray tube having an improved cathode-grid structure which facilitates grid lead connections and mounting. The cathode means has a plurality of openings which are arranged in an array pattern which is identical to the desired electron beam array pattern, and has an emitter means associated with each opening for emitting a group of electrons. The grid means is located behind instead of in front of the cathode means and is comprised of a plurality of grid elements mounted on a substrate. When appropriately biased, the grid elements cause groups of electrons which are emitted by the respective emitter means to flow through the corresponding openings in the cathode in the direction of the screen, thus establishing the required electron beams.

Abstract: An encapsulated planar cathode structure is formed for a vacuum tube. A multibeam cathode ray tube is obtained by heating in the CRT such a structure with a plurality of separated electron emissive layers to remove the encapsulation material. Positive photoresist technology is utilized: for obtaining delineated apertures on a planar metallization layer supported by an insulating substrate into which needle-shaped carbonate particles are deposited electrophoretically normal to the metallization; and for encapsulating the resultant cathodes.

Abstract: A multiple electron beam cathode ray tube has a plurality of cathodes in a plane to form an array. Grids on the same substrate are positioned in spaced relation about the cathodes so that a plurality of individually controlled electron beams are formed when appropriate potentials are applied to the cathodes and grids.
