Publication number: 20080266211Abstract: A priming discharge is generated simultaneously in two adjacent priming discharge cells, and an address operation is performed sequentially in the main discharge cells in the odd rows of the four rows of main discharge cells which are adjacent to the priming discharge cells. After completion of the address operation in all main discharge cells in the odd rows, the priming discharge cells are once initialized. A priming discharge is generated again in the priming discharge cells, and an address operation is performed sequentially this time in the main discharge cells in the even rows which are adjacent to the priming discharge cells. This provides a PDP and a plasma display device which can stably generate an address discharge without narrowing the driving voltage margin of an address operation and reduce the number of driving circuits required for driving the priming electrodes, and also provides a method for driving the PDP.Type: ApplicationFiled: December 14, 2006Publication date: October 30, 2008Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroyasu Makino, Toshikazu Wakabayshi, Hiroyuki Tachibana, Naoki Kosugi, Kazuya Nomoto
