摘要： In a plasma-display-panel driving method, a field period is divided into a plurality of sub fields, each of which has an address period for allowing discharge cells to selectively generate an address discharge and a sustain period for allowing the discharge cells having generated the address discharge to generate a sustain discharge by a number of times corresponding to a brightness weight. In the sustain period, a period for setting display electrode pairs to the base potential is disposed between the sustain pulse for causing the final sustain discharge in the sustain period and the previous sustain pulse. In a time interval corresponding to the lighting ratio of the discharge cells in the sub field after applying to the display electrode pairs a voltage for generating the final sustain discharge, a voltage for reducing the potential difference between electrodes of the display electrode pairs is applied to the display electrode pairs. Accordingly, it is possible to generate a stable address discharge and thus to reduce a crosstalk without increasing the voltage for generating the address discharge.

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 (D1 to Dm) 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 t5, generating setup discharges between the scan electrodes (SC1 to SCn) and the sustain electrodes (SU1 to SUn).
