Patent number: 7518575Abstract: A plasma display device that enables a stable address operation even in a high-speed drive so as to display an image of high definition and high quality. A PDP having discharge cells each provided with a scanning electrode and a sustaining electrode is driven by a method for displaying a frame of an image by repeating an address period, a discharge sustaining period, and a discharge suspend period. At least one initialization period that succeeds a discharge suspend period and in which the state of the wall charge in each discharge cell is initialized is provided. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period.Type: GrantFiled: October 19, 2007Date of Patent: April 14, 2009Assignee: Panasonic CorporationInventors: Nobuaki Nagao, Toru Ando, Masaki Nishimura, Yuusuke Takada

Patent number: 7075234Abstract: A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode (101a) and a second display electrode (101b) has a stepped shape, a film thickness of a discharge gap (Gap1) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L1, L2, L3 (L1>L2>L3). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.Type: GrantFiled: February 12, 2002Date of Patent: July 11, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akira Shiokawa, Ryuichi Murai, Yuusuke Takada, Katutoshi Shindo

Patent number: 7068244Abstract: It is the object of the invention to provide a PDP apparatus and a driving method that can apply pulses at high speeds and can display high-definition, high-quality images by allowing discharge cells to emit light with high luminance and high efficiency. To achieve the object, the pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion, and the second waveform portion starts before a discharge delay time elapses from a start of the first waveform portion.Type: GrantFiled: October 16, 2001Date of Patent: June 27, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuaki Nagao, Toru Ando, Masaki Nishimura, Hidetaka Higashino, Yuusuke Takada
