Abstract: Strips of field emitters (30) arranged in rows overlap grid electrodes (32, 32', 32'') when viewed in the viewing direction (36) to define pixel dots. Scanning electrical voltages are applied to the rows of field emitters (30) to perform scanning and data potentials are applied to the grid electrodes (32, 32', 32'') to control the brightness of the display. Potentials applied to the grid electrodes (32, 32', 32'') also focus the electrons from the field emitters (30). A metal mesh with grid electrodes (32, 32', 32'') fabricated thereon to form an integrated structure greatly simplifies the manufacture of the display.

Abstract: An improved field emission cathode and methods for fabricating such a cathode are disclosed. In the methods of the invention, the field emission cathode is made from at least one body containing a first substance. The method steps include a preparation of irregularities in an emitting surface of the body, adding to the emitting surface of the body ions of a second substance with a low work function, and modifying the emitting surface by inducing field emission in applying a variable electric field to the body and increasing the field strength in steps.

Abstract: A bipolar grid may be positioned between a cathode and an anode. The bipolar grid may receive a positive grid voltage that corresponds to a voltage in an electric field between the cathode and the anode such that the grid does not interfere with an electron beam generated by an electron emitter of the cathode. The bipolar grid may receive a negative grid voltage to isolate the electron emitter such that the electron beam does not reach the anode.

Abstract: Apparatus and method are provided for a package structure that enables mounting of a field-emitting cathode into an electron gun. A non-conducting substrate has the cathode attached and the cathode is electrically connected to a pin through the substrate. Other pins are electrically connected to electrodes integral with the cathode. Three cathodes may be mounted on a die flag region to form an electron gun suitable for color CRTs. Accurate alignment of an emitter array to the apertures in the electron gun and other electrodes such as a focusing lens is achieved. The single package design may be used for many gun sizes. Assembly and attachment of the emitter array to the electron gun during construction of the gun can lower cost of construction.
