Patent number: 8212746Abstract: In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an initializing period for causing initializing discharge in a discharge cell, an address period for selectively causing address discharge in the discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. A holding period when discharge is not caused is disposed before the head subfield belonging to at least one subfield group of the plurality of subfield groups. In the initializing period of the head subfield belonging to at least one subfield group, an initializing operation of causing initializing discharge is performed in the discharge cell where the sustain discharge has been performed in the sustain period of the immediately preceding subfield.Type: GrantFiled: April 10, 2008Date of Patent: July 3, 2012Assignee: Panasonic CorporationInventors: Keiji Akamatsu, Minoru Takeda, Kenji Ogawa, Hiroshi Ibaraki

Patent number: 8207913Abstract: A plasma display panel; a scan electrode drive circuit for generating a gently decreasing downward inclined waveform voltage in an initializing period, a gently increasing first inclined waveform voltage, and a second inclined waveform voltage having a steeper gradient than the first inclined waveform voltage and decreasing immediately after the increasing waveform voltage reaches a predetermined potential in the last part of the sustain period. The lowest voltage in the downward inclined waveform voltage is switched at a first voltage, a second voltage higher than the first voltage and a third voltage higher than the second voltage to generate a downward inclined waveform voltage. The lowest voltage is switched according to the detected temperature to generate the downward inclined waveform voltage.Type: GrantFiled: April 23, 2008Date of Patent: June 26, 2012Assignee: Panasonic CorporationInventors: Hiroshi Ibaraki, Minoru Takeda, Keiji Akamatsu, Kenji Ogawa, Nobuhiko Nakamura
