  • Patent number: 7274143
    Abstract: A plasma display panel has a pair of substrates placed opposite each other with a discharge space in between, electrodes formed on an inner face of one of the pair of substrates, a dielectric layer covering the electrodes, and a protective layer covering the dielectric layer, a discharge gas filling the discharge space. The protective layer includes a cesium-based complex oxide.
    Type: Grant

  • Publication number: 20070042394
    Abstract: The object of the present invention is to provide an apparatus for producing a DNA doped carbon cluster capable of introducing DNA into the cavity of a carbon cluster. An apparatus for producing a DNA doped carbon cluster comprising a radio frequency current applying electrode which is composed of a porous material or a wire mesh capable of retaining a solution containing DNA, a grounding electrode placed opposite to the radio frequency current applying electrode, and a power source for supplying a radio frequency output to the radio frequency current applying electrode, wherein the grounding electrode bears hollow carbon clusters on its surface.

  • Patent number: 7145291
    Abstract: Discharge-gas-filled discharge cells C each having a phosphor layer 7 formed therein are formed between a front substrate 1 and a back substrate 4. A display discharge is produced between paired display electrodes X and Y and an addressing discharge is produced between the display electrode Y and an addressing electrode D in each discharge cell C. In such a plasma display panel, a diamond-containing layer 17A made of a diamond-containing insulation material is formed in a position where the addressing discharge between the display electrode Y and the addressing electrode D in each discharge cell C is produced.

  • Publication number: 20060244683
    Abstract: A method for driving a plasma display panel having column electrodes formed on a front substrate side together with row electrodes. Wall charge adjusting pulses having the same polarity as a sustain pulse are simultaneously applied to respective row electrodes formed in pair for a predetermined period after an addressing stage terminates and before a sustain stage starts in each sub-field.

  • Patent number: 7126279
    Abstract: The front glass substrate and the back glass substrate are placed opposite each other with display cells in between. MIM electron-emitting devices each structured by the opposed cathode electrode and gate electrode sandwiching an insulator layer are arranged in matrix form on the inner face of the front glass substrate. An anode electrode and phosphor layers emitting visible light by being excited by ultraviolet light are provided on the inner face of the back glass substrate. The display cells are filled with an ultraviolet-light-emitting gas generating ultraviolet light by being excited by electrons.
