Patents by Inventor Hatsumi Komaki

Hatsumi Komaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7990065
    Abstract: The PDP has a front panel, and has a back panel with address electrodes formed thereon. Front panel has display electrodes including first electrodes and second electrodes formed on a front glass substrate, and a dielectric layer covering display electrodes. Further, the first electrodes and the dielectric layer include glass frit, which contains at least one of molybdenum oxide, magnesium oxide and cerium oxide, and also include a softening point exceeding 550° C. The above-described makeup suppresses a coloring phenomenon in the dielectric layer and the front glass substrate, thereby implementing a plasma display panel with a high luminance.

  • Publication number: 20110181174
    Abstract: A Plasma Display Panel includes a front panel and a rear panel. The front panel includes a display electrode and a dielectric layer on a glass substrate. The rear panel includes a barrier rib and a phosphor layer on a substrate. The front panel and the rear panel are arranged to face each other, and the peripheries thereof are sealed to form a discharge space therebetween. The display electrode is constituted of multiple layers including at least a metal electrode layer containing silver and a glass material. A content of bismuth oxide (Bi2O3) in the dielectric layer is in a range from 5% to 25% inclusive by weight, and a content of bismuth oxide (Bi2O3) in the glass material of the metal electrode layer is in range from 5% to 25% inclusive by weight.

  • Publication number: 20100248579
    Abstract: A method of manufacturing a PDP in accordance with the present invention is a method of manufacturing a PDP including a front panel having a display electrode, a light blocking layer and a dielectric layer formed on a glass substrate, and a rear panel having an electrode, a barrier rib, and a phosphor layer formed on a substrate, the front panel and the rear panel being disposed facing each other and sealed together at peripheries thereof with discharge space provided therebetween. The method includes forming the display electrode by at least a plurality of layers including metal electrode layer containing silver and a glass material, and a black layer containing a black material and a glass material; adding bismuth oxide to the dielectric layer in the content of 5% by weight or more and 25% by weight or less; and forming the dielectric layer by firing at a temperature ranging from 570° C. to 590° C.

  • Patent number: 7736762
    Abstract: A plasma display panel (PDP) is made of front panel (2) and a rear panel. The front panel includes display electrodes (6), dielectric layer (8), and protective layer (8) that are formed on front glass substrate (3). The rear panel includes electrodes, barrier ribs, and phosphor layers that are formed on a rear glass substrate. The front panel and the rear panel are faced with each other, and the peripheries thereof are sealed to form a discharge space therebetween. Display electrodes (6) includes metal electrodes (4b, 5b) each containing at least silver and binding glass. The binding glass of black electrodes (41b, 51b) and white electrodes (42b, 52b) constituting metal bus electrodes (4b, 5b) contains at least bismuth oxide and has a softening point exceeding 550° C.
