Patent number: 6242860Abstract: A plasma display panel has a first substrate, a plurality of address electrodes disposed on the first substrate, a first dielectric layer disposed on the first substrate in covering relation to the address electrodes, a second substrate, a plurality of scan electrodes disposed on the second substrate in a direction transverse to the address electrodes, a second dielectric layer disposed on the second substrate in covering relation to the scan electrodes. The first substrate and the second substrate are disposed in confronting relation to each other with discharge spaces defined therebetween. The first dielectric layer contains electrically conductive particles mixed therewith. The electrically conductive particles make the first dielectric layer electrically conductive in its transverse direction to allow charges stored on the first dielectric layer to leak to the address electrodes for thereby reducing the frequency of random discharges.Type: GrantFiled: March 6, 1997Date of Patent: June 5, 2001Assignee: Fujitsu LimitedInventors: Hiromichi Sasao, Hiroyuki Nakahara, Toshiyuki Nanto, Akira Otsuka, Noriyuki Awaji, Keiichi Betsui, Shinji Tadaki

Patent number: 6195073Abstract: The present invention relates to a plasma generation method of a plasma display panel. The plasma display panel comprises a first substrate and a second substrate positioned in parallel with each other, an ionizable gas filled between the two substrates, and a plurality of first, second, third and fourth electrodes installed on the two substrates. The first and second electrodes are alternately installed in parallel on the first substrate. The third electrodes are installed on the second substrate perpendicular to the first and second electrodes. An area between one of the third electrodes and a pair of neighboring first and second electrodes define a display unit for generating plasma from the ionizable gas in the display unit and driving the plasma. The third electrode of each display unit is used for determining if the plasma within the display unit should remain.Type: GrantFiled: August 28, 1998Date of Patent: February 27, 2001Assignee: Acer Display Technology, Inc.Inventor: Chu-Shan Lin
