Plasma display panel drive circuit and plasma display device

A plasma display panel drive circuit, in which multiple scan electrodes included in a plasma display panel is divided into at least first and second scan electrode groups, and a setup pulse is supplied in a setup period, scan pulses are supplied in a scan period and sustain pulses are supplied in a sustain period, the plasma display panel drive circuit, comprising:

• a first scan electrode group drive section, including a scan peak potential producing section to produce a predetermined peak potential, operable to produce scan pulses based on the scan peak potential and to supply the scan pulses to said first scan electrode group in a first sub-scan period within the scan period;
• a second scan electrode group drive section operable to produce scan pulses based on the scan peak potential of said scan peak potential producing section and to supply the scan pulses to said second scan electrode group in a second sub-scan period after the first sub-scan period within the scan period;
• and
• a complex switch section operable to supply the scan peak potential of said scan peak potential producing section to said second scan electrode group drive section in the second sub-scan period within the scan period,
• wherein said complex switch section includes an inter-group switch section operable to supply and shut off the scan peak potential of said scan peak potential producing section to said second scan electrode group drive section, and
• wherein said inter-group switch section is turned off in the first sub-scan period and turned on in the second sub-scan period.
