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： A two-phase driving operation is performed by a first circuit and a second circuit in at least one sub-field. The first circuit applies a first ramp waveform that drops from a first potential to a second potential to a plurality of first scan electrodes in a setup period, and sequentially applies a scan pulse to the plurality of first scan electrodes in a write period. The second circuit applies a second ramp waveform that drops from the first potential to a third potential that is higher than the second potential to a plurality of second scan electrodes in the setup period, and holds the second scan electrodes at a fourth potential that is higher than the third potential in a period where the scan pulse is applied to the first scan electrodes, and then sequentially applies a scan pulse to the plurality of second electrodes in the write period. Discharge failures during write discharges can be prevented from occurring by applying the two-phase driving operation.

摘要： One field period includes a plurality of subfields each having an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, a writing period in which a negative scan pulse voltage is applied to the scan electrode, and a sustain period. A sloping waveform voltage is generated by switching a minimum voltage in the sloping waveform voltage between a first voltage and a second voltage that has a lower voltage value than that of the first voltage. The ratio in one field period of a subfield in which an initialization is carried out by the sloping waveform voltage whose minimum voltage is the second voltage is increased when a temperature of the plasma display panel is determined to be low as compared with when the temperature is determined to be not low.

摘要： In displaying a predetermined image on a plasma display panel, occurrence of an initializing bright point can be suppressed to reduce the maximum voltage in an all-cell initializing operation, light emission in the all-cell initializing operation is suppressed to reduce the black luminance, and the contrast is sharpened. In driving the plasma display panel, one field period includes a plurality of subfields having a setup period for causing initializing discharge in discharge cells, an address period, and a sustain period. One field period includes at least one subfield for applying ramp waveform voltage increasing in the setup period to the scan electrodes. The maximum voltage of the ramp waveform voltage can be varied. When a predetermined image establishing a previously determined condition is displayed, the ramp waveform voltage is generated whose maximum voltage is smaller than when an image other than the predetermined image is displayed, and a positive voltage is applied to the data electrodes at least while the ramp waveform voltage having the smaller maximum voltage is applied to the scan electrodes.
