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: 7140940Abstract: The present invention intends to provide a manufacturing method for a PDP that can continuously apply phosphor ink for a long time and can accurately and evenly produce phosphor layers even when the cell construction is very fine. To do so, phosphor ink is continuously expelled from a nozzle while the nozzle moves relative to channels between partition walls formed on a plate so as to scan and apply phosphor ink to the channels. While doing so the path taken by the nozzle within each channel between a pair of partition walls is adjusted based on position information for the channel. When phosphor particles is successively applied to a plurality of channels, phosphor ink is continuously expelled from the nozzle even when the nozzle is positioned away from the channels. The phosphor ink is composed of: phosphor particles that have an average particle diameter of 0.Type: GrantFiled: October 18, 2002Date of Patent: November 28, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyuki Kawamura, Shigeo Suzuki, Masaki Aoki, Kanako Miyashita, Mitsuhiro Ohtani, Hiroyuki Kado, Keisuke Sumida, Nobuyuki Kirihara
