Patent number: 7218292Abstract: A method of driving a plasma display panel including (A) a first substrate including a first electrode, and a second electrode extending in parallel with the first electrode and defining a display area with the first electrode therebetween, and (B) a second substrate including a third electrode facing the first and second electrodes and extending perpendicularly to the first and second electrodes, includes (a) applying a serrate voltage having an inclined waveform in which a voltage varies with the lapse of time, to the first and/or second electrodes, and (b) applying a preliminary charge-eliminating pulse voltage to the first and/or second electrodes after the a charge-eliminating discharge has been generated due to the serrate voltage, wherein the preliminary charge-eliminating pulse voltage eliminates electric charges only when electric charges have not been sufficiently eliminated.Type: GrantFiled: December 10, 2003Date of Patent: May 15, 2007Assignee: Pioneer CorporationInventors: Yukinori Kashio, Mitsuhiro Ishizuka, Shinya Tsuchida, Takatoshi Shoji, Koji Hashimoto, Akihiro Ueki

Publication number: 20050104808Abstract: There is provided a method of driving a plasma display panel including a first substrate, a second substrate, and a plurality of display cells. The first substrate includes a first electrode, and a second electrode extending in parallel with the first electrode and defining a display line with the first electrode therebetween. The second substrate includes a third electrode facing the first and second electrodes, and extends in such a direction which intersects with a direction in which the first and second electrodes extend. The display cells are arranged at intersections of the first and second electrodes with the third electrode. The method includes the step of applying a voltage having such a serrate waveform that a voltage varies with the lapse of time, to at least one of the first and second electrodes, a final voltage of a sustaining-eliminating voltage being higher than a final voltage of a priming-eliminating voltage.Type: ApplicationFiled: September 28, 2004Publication date: May 19, 2005Inventor: Yukinori Kashio

Patent number: 6862007Abstract: A method for driving an alternating current (AC) plasma display panel is provided which is capable of making sustaining light emission inconspicuous caused by erroneous discharge during a period when supply power becomes stable even if erroneous discharge occurs due to an influence of residual charges produced at a time of starting operations of the AC plasma display panel. A driving method for one frame is changed between a period (supply power stability waiting period) required until the supply power becomes stable and a display period. Time required until a voltage becomes stable is for example 0.5 seconds to 1 second after power-ON. In a field during this period, one field is divided into a plurality of sub-fields and the number of repeated pulses is smaller during a sustaining period of each sub-field than that of repeated pulses during a sustaining period of a sub-field in the display period. For example, no sustaining pulse is fed to a scanning electrode.Type: GrantFiled: October 25, 2002Date of Patent: March 1, 2005Assignee: NEC Plasma Display CorporationInventors: Takatoshi Shoji, Yukinori Kashio

Patent number: 6720941Abstract: A method for driving a surface-discharge AC (alternating current)-type PDP (Plasma Display Panel) is provided which is capable of shortening a scanning period by securing a wide range in which a voltage to induce sustaining discharge can be set without causing flicker to occur and without causing black luminance to be increased. A sub-field is made up of a resetting period, a scanning period, a wall charge forming period, and a sustaining period. During the scanning period, time interval between scanning pulses is shortened. During the wall charge forming period, each of common electrodes and data electrodes is made to be at a ground potential and a wall charge forming pulse having a same potential as that of a scanning pulse is applied to all scanning electrodes. The time interval between wall charge forming pulses is for example 3 &mgr;sec to 50 &mgr;sec. This causes space charges being left in a display cell to be attracted on each of electrodes, whereby wall charges build up.Type: GrantFiled: December 2, 2002Date of Patent: April 13, 2004Assignee: NEC Plasma Display CorporationInventor: Yukinori Kashio

Patent number: 6411268Abstract: A plasma display unit applies data pulses of a predetermined polarity to data electrodes in odd-numbered columns and applies data pulses of an opposite polarity to data electrodes in even-numbered columns. The plasma display unit applies scanning pulses which are inverted between positive and negative polarities in first and second states that occur alternately, to scanning electrodes in odd-numbered rows, and applies scanning pulses which are inverted between positive and negative polarities in the first and second states in opposite relation to the scanning pulses applied to the scanning electrodes in odd-numbered rows, to scanning electrodes in even-numbered rows. Pixels arranged vertically and horizontally in a two-dimensional matrix are alternately energized in a staggered grid pattern, so that the number of pixels that are simultaneously energized is half the number of pixels of a conventional plasma display unit.Type: GrantFiled: December 23, 1999Date of Patent: June 25, 2002Assignee: NEC CorporationInventors: Tadashi Nakamura, Masayuki Kimura, Mitsuhiro Ishizuka, Shinji Hirakawa, Yukinori Kashio
