Publication number: 20060055325Abstract: A plasma display panel has a front glass substrate and a back glass substrate facing each other on either side of a discharge space, row electrode pairs formed on the rear-facing face of the front glass substrate, and a dielectric layer covering the row electrode pairs. Discharge cells are formed in the discharge space. The PDP further has crystalline MgO layers each provided on a part of portion of the face of the front glass substrate having the row electrode pairs formed thereon and facing toward the discharge space. The crystalline MgO layers include magnesium oxide crystals causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by an electron beam.Type: ApplicationFiled: September 15, 2005Publication date: March 16, 2006Applicant: Pioneer CorporationInventors: Atsushi Hirota, Eishiro Otani, Hai Lin, Kunimoto Tsuchiya

Patent number: 6995512Abstract: A partition wall defines individual discharge cells. A second lateral wall partitions each of the discharge cells into a display discharge cell opposing two transparent electrodes of the paired row electrodes and allowing for a sustain discharge, and an addressing discharge cell opposing a bus electrode of one of the paired row electrodes and allowing for an addressing discharge produced between the bus electrode and a column electrode. A clearance is provided between the display discharge cell and the addressing discharge cell to establish communication from the addressing discharge cell to the display discharge cell. A high ? material layer is provided on an area facing the addressing discharge cell.Type: GrantFiled: March 10, 2004Date of Patent: February 7, 2006Assignee: Pioneer CorporationInventor: Eishiro Otani

Publication number: 20040164932Abstract: A plasma display panel includes a front substrate and a rear substrate, with a discharge space therebetween. Row and column electrodes extend on an inner surface of the front substrate. Each display line is defined by paired two adjacent row electrodes. A dielectric layer covers the row electrodes. Unit light-emission areas are formed in the discharge space at intersections of the row and column electrodes. A partition wall matrix comparts the unit light-emission areas from each other. A separation wall divides each unit light-emission area into a first discharge cell, in which discharge occurs across the paired two adjacent row electrodes associated with that unit light-emission area, and a second discharge cell, in which discharge occurs across one of the paired two adjacent row electrodes and the column electrode concerned. The first discharge cell communicates with the second discharge cell via a passage in each unit light-emission area.Type: ApplicationFiled: February 24, 2004Publication date: August 26, 2004Applicant: PIONEER CORPORATIONInventors: Eishiro Otani, Kazuo Yahagi

Patent number: 6703782Abstract: In a surface-discharge-type alternating-current plasma display panel, a discharge cell is divided into two cells: a display discharge cell C1 providing for a sustaining discharge between transparent electrodes Xa, Ya of row electrodes X, Y; and an addressing discharge cell C2 which is opposite a bus electrode Yb of the row electrode Y, giving rise to an addressing discharge in association with a column electrode D, to provide for the addressing discharge between the bus electrode Yb of the row electrode Y and a column electrode D. The display discharge cells C1 and the addressing discharge cells C2 of the discharge cells are interposed in alternate positions in the column direction so as to arrange the addressing discharge cells C2 in a back-to-back position in the column direction.Type: GrantFiled: December 2, 2002Date of Patent: March 9, 2004Assignees: Pioneer Corporation, Pioneer Display Products CorporationInventors: Eishiro Otani, Chiharu Koshio, Hitoshi Taniguchi

Publication number: 20040008164Abstract: A display panel device includes a plurality of row electrode pairs and a plurality of column electrodes. Each row electrode pair includes a first and second electrodes. Unit light emission areas are formed at intersections of the row electrode pairs and the column electrodes. Each unit light emission area includes a first discharge cell and a second discharge cell. The second discharge cell includes a light-absorbing layer and secondary electron emission material layer. When driving the display panel device, sustain discharge responsible for light emission governing the display image is induced in the first discharge cells, whereas reset discharge and address discharge accompanied by light emission not contributing to the display image is induced in the second discharge cells.Type: ApplicationFiled: July 10, 2003Publication date: January 15, 2004Applicant: PIONEER CORPORATION & PIONEER DISPLAY PRODUCTS CORPORATIONInventors: Eishiro Otani, Kimio Amemiya, Yoichi Sato, Tsutomu Tokunaga

Patent number: 6674238Abstract: In a plasma display panel, a partition wall 15 surrounds each of discharge cells to define the discharge cells. Each of the discharge cells is divided by a second transverse wall 15B into a display discharge cell C1 which is opposite transparent electrodes Xa, Ya of paired row electrodes X, Y to provide for a sustaining discharge; and an addressing discharge cell C2 which is opposite a bus electrode Yb of the row electrode Y to provide for an addressing discharge caused between the bus electrode Yb and a column electrode D. A clearance r is provided between the discharge cell C1 and the addressing discharge cell C2 for communication between the cells C1 and C2.Type: GrantFiled: June 28, 2002Date of Patent: January 6, 2004Assignees: Pioneer Corporation, Pioneer Display Products CorporationInventors: Eishiro Otani, Hitoshi Taniguchi, Chiharu Koshio, Yoichi Sato

Publication number: 20030067425Abstract: A plasma display panel capable of improving dark contrast. A unit light emission region is comprised of a display discharge cell in which a discharge is produced between portions of row electrodes X, Y of each row electrode pair (X, Y) opposing each other, and a reset and address discharge cell arranged in parallel with the display discharge cell, in which a discharge is produced between portions of the row electrode Y and a row electrode X of another adjacent row electrode pair (X, Y). The display discharge cell and reset and address discharge cell are communicated with each other. A light absorbing layer is formed in a portion of the reset and address discharge cell opposing the display surface. According to another aspect, the unit light emission region in the display panel comprises a first discharge cell and a second discharge cell comprising a light absorbing layer.Type: ApplicationFiled: September 13, 2002Publication date: April 10, 2003Applicant: PIONEER CORPORATIONInventors: Tsutomu Tokunaga, Nobuhiko Saegusa, Kazuo Yahagi, Mitsushi Kitagawa, Ryo Suzue, Eishiro Otani, Yoichi Sato
