Abstract: A matrix addressable flat panel display includes a flat cathode operable for emitting electrons to an anode when an electric field is produced across the surface of the flat cathode by two electrodes placed on each side of the flat cathode. The flat cathode may consist of a cermet or amorphic diamond or some other combination of a conducting material and an insulating material such as a low effective work function material. The electric field produced causes electrons to hop on the surface of the cathode at the conducting-insulating interfaces. An electric field produced between the anode and the cathode causes these electrons to bombard a phosphor layer on the anode.

Abstract: A first display discharge lamp has a transparent airtight container filled with a discharge gas; a positive electrode disposed in the airtight container and supported by a stem having an air tube therein; a negative electrode of an inverted configuration disposed in the transparent airtight container and surrounded by the positive electrode; a lead member integrally formed with the positive electrode, having a bent portion between a lower end of the negative electrode and the stem; and an insulating member disposed between the lower end of the negative electrode and the bent portion of the lead member. According to a second display discharge lamp, both a negative electrode and a positive electrode are of an inverted conical configuration. The former has at least an open upper end, while the latter has an open upper end and an open lower end. A lower end of the positive electrode is inserted in an interior of the negative electrode from the open upper end of the negative electrode. And, a lower/outer periphery of the positive electrode is, in a non-contact condition, opposed to an upper/inner periphery of the negative electrode.

Abstract: A hot cathode in a wire form is useful in a vacuum tube, a CRT or a fluorescent display tube is disclosed. The cathode is composed of a heat-resistant metal in a wire form that holds on it an electron-emitting metal material that is made of 0.2-20 wt % of a rear earth metal oxide in admixture with an alkaline earth metal oxide the balance of which contains at least barium oxide. The reduction of oxide barium to barium as a result of reaction with the cathode wire is so much retarded that an increased emission current will be produced from the cathode not only in its initial operation but also through out its operation.
