摘要： A field emission cathode capable of reducing an operation voltage and substantially preventing damage of an emitter. An emitter is provided on a substrate. The emitter includes a base and a plurality of rectangular tips projecting from the base. A gate is arranged in a recess formed on the substrate so as to be in proximity to the emitter. A width a of the tips of the emitter and an interval b between the tips are defined to satisfy a relationship of b/a=2. This permits an electric field strength applied to the tips of the emitter to be substantially increased as compared in a conventional field emission cathode of b/a.ltoreq.1, resulting in an operation voltage being reduced and a sufficient amount of emitter current being produced.

摘要： An electron feed structure for a flat-type luminous device capable of permitting electron emitted from an electrons source to be uniformly fed throughout a display section. The electron feed structure includes an electron flow guide constituted by an inner guide electrode of a high voltage and an outer guide electrode of a low voltage, so that an electric field of a high voltage and that of a low voltage may be alternately formed to form electrostatic lenses in the guide, to thereby effectively prevent the function of the electron flow guide from being deteriorated. A guide voltage applied to each of the electrode segments of the inner guide electrode is rendered constant and a guide voltage applied to each of the electrode segments of the outer guide electrode is likewise rendered constant, to thereby cause the correlation between the guide voltage and a deflection voltage applied to the electron flow guide to be uniform irrespective of a position within the electron flow guide, resulting in electrons emitted from the electron source being drawn out under the same conditions.

摘要： A field emission cathode that can uniform the number of electrons emitted from each emitter and can prevent a line defect even when a gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode, so that the current supplied from the cathode electrode to the emitter can be controlled. If the emitter is short-circuited with the gate electrode, the increased current density destroys the channel, so that the current supply to the emitter can be stopped.

摘要： A vacuum envelope with a built-in electron source capable of preventing peeling of gate electrodes, to thereby enhance reliability in operation over a long period of time and reducing a manufacturing cost thereof. The gate electrodes each are made of niobium oxide or niobium nitride. Nb for the gate electrode is previously oxidized or nitrided to prevent progress of oxidation of the gate electrode due to release of oxygen from lead oxide contained in a seal material during heating for sealing, resulting in expansion of the gate electrode. An insulating layer is formed on a cathode substrate and the gate electrodes are formed on the insulating layer. Then, the seal material is applied onto the insulating layer so as to cover a part of each of the gate electrodes, so that the cathode substrate may be sealedly joined to an anode substrate.

摘要： Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.
