Patent number: 7471042Abstract: An object of the present invention is to provide a technique for relatively easily suppressing the yellowing of a Plasma Display Panel in which electrodes comprising silver are disposed on the substrates, and thus render image displays with high luminance and high quality. In order to achieve the object, an arrangement is made in which the electrodes comprising silver further include an element whose standard electrode potential is lower than that of silver, such as Cr, Al, In, B, and Ti, or a compound of such an element, as a silver ionization inhibiting substance.Type: GrantFiled: February 5, 2002Date of Patent: December 30, 2008Assignee: Panasonic CorporationInventors: Morio Fujitani, Hiroyuki Yonehara, Masaki Aoki, Keisuke Sumida, Hideki Asida, Junichi Hibino, Daisuke Adachi

Patent number: 7453206Abstract: A PDP has first and second substrates which face each other with a space in between. A display electrode pair and a dielectric layer are formed on the first substrate, and a plurality of discharge cells are formed between the first and second substrates along the display electrode pair. In this construction, two or more depressions are provided in the dielectric layer in an area corresponding to each discharge cell. This improves luminous intensity and illumination efficiency. Also, to form the dielectric layer on the first substrate, first a transfer film is made by providing a dielectric precursor layer on a support film, then depressions are formed in the dielectric precursor layer of the transfer film, and lastly the dielectric precursor layer of the transfer film is transferred onto the first substrate. This decreases the number of manufacturing steps and increases the yield, thereby reducing manufacturing costs.Type: GrantFiled: May 27, 2002Date of Patent: November 18, 2008Assignee: Panasonic CorporationInventors: Morio Fujitani, Hiroyuki Yonehara, Masaki Aoki, Keisuke Sumida, Hideki Asida, Junichi Hibino

Patent number: 7063584Abstract: A manufacturing method for a gas discharge display panel includes a disposing step of disposing on a substrate, material of one of an electrode, a dielectric layer, a barrier rib, and a phosphor layer; and a baking step of baking the substrate on which the material has been disposed, while the substrate is carried on a support platform. The support platform has at least one channel in a surface thereof on which the substrate is placed, extending from a covered area covered by the substrate through to an exposed area not covered by the substrate.Type: GrantFiled: May 28, 2002Date of Patent: June 20, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Yonehara, Masaki Aoki, Keisuke Sumida, Morio Fujitani, Hideki Asida

Patent number: 7034458Abstract: A manufacturing method for a metal electrode used for a bus electrode, a data electrode, and the like which make up a display panel including a PDP (Plasma Display Panel) by which, when these electrodes are patterned according to a photolithographic method, the edge curl phenomenon can be substantially controlled to the extent that the phenomenon is negligible. The manufacturing method of the invention therefore includes a dry step for drying the layers making up the metal electrode so that flows (F1, F2, and F3) of the solvent occur from a region having a high absorbency of the solvent to a region having a lower absorbency of the solvent.Type: GrantFiled: February 8, 2005Date of Patent: April 25, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hideki Asida, Shinya Fujiwara, Hideki Marunaka, Tadashi Nakagawa, Keisuke Sumida, Hideaki Yasui, Kazuhiko Sugimoto, Hiroyosi Tanaka

Patent number: 7002297Abstract: To provide a technique for relatively easily preventing yellowing of a PDP that uses silver electrodes, and a PDP utilizing the technique that is capable of displaying images with high luminance and high quality. To form the electrodes, an alloy composed of Ag as a main constituent and a transition metal (at least one selected from Cu, Cr, Co, Ni, Mn, and Fe) is used, or an oxide of such a transition metal is added. Alternatively, an alloy composed of Ag as a main constituent and a metal (at least one selected from Ru, Rh, Ir, Os, and Re) is used, or an oxide of such a metal is added. Alternatively, Ag particles whose surfaces are each coated with a metal (Pd, Cu, Cr, Ni, Ir, or Ru) or a metal oxide (SiO2, Al2O3, NiO, ZrO2, Fe2O3, ZnO, In2O3, CuO, TiO2, or Pr6O11) are used.Type: GrantFiled: June 23, 2004Date of Patent: February 21, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaki Aoki, Mitsuhiro Ohtani, Junichi Hibino, Keisuke Sumida, Hideki Asida, Shinya Fujiwara, Hideki Marunaka, Tadashi Nakagawa

Publication number: 20050041001Abstract: A plasma display panel includes a first panel member in which a plurality of pairs of display electrodes are arranged so as to be adjacent to each other in a column direction and a second panel member in which a plurality of address electrodes are arranged so as to be adjacent to each other in a row direction, and the first panel member and the second panel member are opposed to each other so that a plurality of cells are formed in a matrix in areas where the plurality of pairs of display electrodes intersect with the plurality of address electrodes. The plasma display panel is characterized in that at least one of an average cell area, an average cell opening ratio and an average visible light transmittance efficiency is greater in a panel central region than in a panel peripheral region.Type: ApplicationFiled: May 28, 2001Publication date: February 24, 2005Inventors: Keisuke Sumida, Hiroyuki Yonehara, Morio Fujitani, Hideki Asida

Publication number: 20040239246Abstract: A plasma display panel includes a substrate on which a plurality of electrodes formed by sintering a conductive material are arranged. Each electrode has a first part that is positioned within a display area on the substrate, and a second part that is positioned outside the display area on the substrate and has a smaller film thickness than the first part.Type: ApplicationFiled: July 19, 2004Publication date: December 2, 2004Inventors: Hideki Asida, Hiroyuki Yonehara, Keisuke Sumida, Morio Fujitani, Junichi Hibino, Shinya Fujiwara, Hideki Marunaka, Tadashi Nakagawa -
Publication number: 20040232839Abstract: A glass paste used as a starting material of a transparent dielectric of a plasma display panel (“PDP”), the glass paste enabling the baking time required in forming a dielectric layer of the PDP to be shortened without reducing the transmissivity of the dielectric layer. A decomposition accelerator for accelerating the decomposition of an organic component is included in the glass paste so as to contact with the organic component. As a result, the decomposition of the organic component is accelerated when the glass paste is baked. Moreover, since the organic component is substantially eliminated before the baking temperature reaches a temperature at which a glass powder in the glass paste begins to melt, gas from decomposing organic component is not generated when the glass powder melts, and consequently the trapping of gas bubbles within the dielectric layer is prevented.Type: ApplicationFiled: June 24, 2004Publication date: November 25, 2004Inventors: Morio Fujitani, Hiroyuki Yonehara, Masaki Aoki, Hideki Asida, Junichi Hibino
