Publication number: 20030107563Abstract: A driving system comprises a driver circuit subsystem that drives cells of a plasma display panel (PDP), a detector subsystem that detects vertical sync signals in an input video signal at preset time intervals, a self-running sync signal generator subsystem that generates sync signals of a self-running type based on a clock thereof, and a sync signal switching subsystem that outputs the self-running sync signals in place of the vertical sync signals when the vertical sync signals are not detected. When input video signals are absent, the driving system uses the self-running sync signals to perform display control over the PDP.Type: ApplicationFiled: November 6, 2002Publication date: June 12, 2003Applicant: PIONEER CORPORATIONInventor: Naruhiro Sato
