Abstract: In one embodiment of the present invention, an electron/photon source is disclosed based on field emission, cathodoluminescent and photo-enhanced field emission, including an evacuated chamber inside a housing, further including an anode and a cathode arranged inside the evacuated chamber. Furthermore, the cathode is arranged to emit electrons when a voltage is applied between the anode and cathode, the anode being arranged to emit light at a first wavelength range when receiving electrons emitted from the cathode, and a wavelength range converting material arranged to receive the emitted light of the first wavelength range and emit light at a second wavelength range. In a novel way, an embodiment of the present invention makes it possible to, in two steps, convert the electrons emitted from the cathode to visible light. The invention has shown to be advantageous, and makes it possible to select new emission materials, manufactured at a fraction of the cost associated with the earlier used materials where the electron to visible light conversion was done in one step.

Abstract: A method for forming flat display panel phosphor dots is disclosed wherein a conventional printing method or procedure is used in combination with an optical method.The paste film containing the phosphor, photoresist and powdered glass is coated on the surface of the dielectric layer, e.g. lead glass layer by means of the printing method. The paste layer is irradiated by a ultraviolet light through a mask, and after the development of the paste layer has been completed, the remaining hardened portions of the paste layer are subjected to a heat treatment. In this way, phosphor dots having a desired shape can be formed very firmly and very exactly at certain predetermined portions on said dielectric layer.

Abstract: A plurality of control plates is sandwiched between a cathode and a target to control the flow of charged particles such as electrons and ions between the cathode and the target. The cathode includes an elongated filament for generating charged particles such as electrons. A first electrode is positioned behind the filament with a second electrode having a positive potential interdigitated with the first electrode. The first electrode is divided into segments with a negative potential applied to those segments of first electrode where emission is desired from the elongated filament, and in those areas were emission is not desired those segments of the first electrode are switched sufficiently negative to cut off emission from the elongated filament. Each control plate has a plurality of apertures formed therein which are effectively aligned with corresponding apertures on the other control plates. The aligned apertures form beam channels. The control plates have paired conductive electrodes thereon arranged at predetermined coded finger patterns. Voltages are selectively applied to the control plate electrodes by switching circuitry to focus the charged particles through the apertures associated with selective electrodes while simultaneously aborting the passage of charged particles through the apertures associated with the remaining electrodes. In this manner by selective switching control of the control plate a beam, or a plurality of beams, can be directed to a selected portion or portions of the target at the time.

Abstract: A flat cathode ray tube device is provided for display of information by response to an electron beam of a phosphor coating on a face plate. A monolithic structure includes an x-y matrix of electron source cathodes and a pair of grid arrays successively spaced from the matrix with holes therethrough adjacent to and aligned with the cathodes selectively to form and individually control the intensity of an electron beam from each of said cathodes. Deflection control structure has holes through which the beams may pass with a set of x-y deflection electrodes associated with each of the holes for x-y control of the trajectory of each of the beams. A support plate forms the base of the monolithic structure with the cathodes mounted thereon and a face plate structure marginally sealed to the support plate provides a vacuum tight envelope housing the monolithic structure.
