DRIVING DEVICE AND DRIVING METHOD OF PLASMA DISPLAY PANEL, AND PLASMA DISPLAY APPARATUS

摘要

A driving device drives a plasma display panel having a plurality of discharge cells at intersections of a plurality of scan electrodes and a plurality of sustain electrodes with a plurality of data electrodes by a sub-field method. A scan electrode drive circuit applies a first ramp waveform that drops from a first potential to a second potential to the plurality of scan electrodes in a first period in a setup period of a sub-field. A sustain electrode drive circuit applies a second ramp waveform that drops from a fourth potential to a fifth potential to the plurality of sustain electrodes when a potential detection circuit detects that the plurality of scan electrodes attain a third potential that is lower than the first potential and higher than the second potential in the first period.
