摘要： A voltage of sustain electrodes (SU1 to SUn) is lowered from Ve1 to a ground potential at a time point t1 immediately before a first SF (sub-field). Then, a pulsed positive voltage Vd is applied to data electrodes (D1 to Dm) at a starting time point t2 of a setup period of the first SF. Immediately before this, a large amount of negative wall charges is stored on the sustain electrodes (SU1 to SUn) and positive wall charges are stored on the data electrodes (D1 to Dm), and therefore application of the pulsed positive voltage Vd to the data electrodes generates strong discharges between the sustain electrodes (SU1 to SUn) and the data electrodes (D1 to Dm). After that, application of a ramp voltage to scan electrodes (SC1 to SCn) is started at a time point t3, generating setup discharges between the scan electrodes (SC1 to SCn) and the sustain electrodes (SU1 to SUn).

摘要： In a plasma display device, a period for connecting display electrode pairs to the base potential is disposed between a sustain pulse for generating the final sustain discharge and the previous sustain pulse based on a lighting ratio of the discharge cells in the corresponding subfield, and a voltage for reducing an interelectrode potential difference of the display electrode pairs is applied to the display electrode pairs in a predetermined time period corresponding to the lighting ratio of the discharge cells in the corresponding subfield after applying the sustain pulse for generating the final sustain discharge to the scan electrodes.
