    摘要: A conductive refractory compound coating for electrodes is sputter resistant, very resistant to oxidation, and easy to apply by way of electrophoresis or screen printing. This structure is further enhanced by the presence of surface particles of electrically nonconductive ceramic material. when the cathode electrode is energized, electrically nonconductive material is penetrated by the electric field, which attracts secondary electrons out of the cathode electrode, thereby increasing the cathode's efficiency as an emitter of secondary electrons. More specifically, cathode electrodes are used in a plasma addressing structure. The coating is formed by approximately 5 nm particles, each comprised of a fused matrix of conductive and nonconductive particles co-deposited with frit particles by either electrophoresis or "silk" screening. The coating is subsequently baked to fuse the frit and bond the electrophoretically deposited particles to the electrodes.

    摘要: L'invention concerne les écrans de visualisation du type panneaux à plasma. Elle a pour but d'améliorer le contraste d'image.
    Le panneau à plasma de l'invention comprend une dalle avant (D1), portant des éléments photoluminescents (LB1, LV1) constitués par des grains (GL1, GLn) de matériau luminophore. Suivant une caractéristique de l'invention, les grains (GL1, GLn) ont un diamètre inférieur à 1,5 micromètre.
    Ceci constitue, par rapport à l'art antérieur, une importante réduction du diamètre des grains luminophores, qui conduit à réduire le coefficient de réflexion diffuse, d'où il résulte une amélioration du contraste de l'image.

    摘要: A hollow cathode (16) capable of self-heating by back ion bombardment to a thermionic emission temperature axially discharges therefrom an ionized plasma (26) of an ambient gas (14) such as xenon. Electrons are axially or radially extract­able from the plasma (26) by an anode (18). A voltage is applied to a keeper electrode (20) disposed between the cathode (16) and anode (18) to sustain plasma (26) discharge of the gas (14) between the cathode (16) and keeper electrode (20). A control electrode (22) is disposed between the keeper electrode (20) and the anode (18). Application of a positive voltage (relative to the cathode) to the control electrode (22) causes the plasma (26) discharge to extend from the cathode (16) to the anode (18), thus closing the switch. Application of a negative control electrode (22) voltage, or simply return­ing the control electrode (22) to cathode (16) potential, causes the plasma (26) discharge to retract back to the area of the keeper electrode (20), thereby opening the switch.

    摘要: A plasma display panel comprises a front plate disposed on the side of a viewer, a rear plate disposed in parallel and opposing the front plate, and cell barriers arranged between the front and rear plates of matrix shape or linear shape. The cell barrier is formed of a material including a phosphor. The cell barriers are formed by printing multiple times a phosphor paste containing glass frit in an overlapped manner by a screen printing method. The cell barrier is formed in another method in which a positive pattern of cell barriers are formed on the front or rear plate by using photo resist, a slurry containing a phosphor fills in portions except for the pattern of the photo resist, and the photo resist is thereafter removed to thereby form cell barriers. In the case of the cell barrier of a color display PDP, the cell barrier may be composed of a material containing phosphor of different colors each with a width corresponding to a one half width of the cell barrier.

    摘要: Apparatus for forming an electron beam sheet includes a cathode member 5 having a slot 6 in a front surface thereof, a grid electrode 4 and the anode 1 of a thyratron. When it is desired to trigger the thyratron into conduction, a suitably large potential difference is applied between the cathode member 5 and the grid 4, resulting in a electron beam sheet being produced extensive of a slot 6 formed in the front surface of the cathode member 5. This produces ionisation and a main discharge current is established between the main anode 1 and cathode 2 of the thyratron.
