摘要： One field period includes a plurality of subfields each having (i) an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, (ii) a writing period in which a negative scan pulse voltage is applied to the scan electrode, and (iii) 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. A number of subfields, in which an initialization is carried out by the sloping waveform voltage having the minimum voltage as the second voltage, is increased when a temperature of a plasma display panel is determined to be low as compared with when the temperature is determined to be not low.

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： 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).
摘要翻译：在第一SF（子场）之前的时刻t1，维持电极（SU1〜SUn）的电压从Ve1降低到接地电位。然后，在第一SF的建立周期的起始时间点t2向数据电极（D1〜Dm）施加脉冲正电压Vd。在此之前，在维持电极（SU1〜SUn）上存储大量的负壁电荷，在数据电极（D1〜Dm）上存储正的壁电荷，因此将脉冲正电压Vd施加到数据电极在维持电极（SU1〜SUn）和数据电极（D1〜Dm）之间产生强放电。之后，在时间点t3开始对扫描电极（SC1〜SCn）施加斜坡电压，在扫描电极（SC1〜SCn）和维持电极（SU1〜SUn）之间产生建立放电。

The plasma display apparatus has a plasma display panel and a driver circuit for driving the panel. In this driving method, right-eye images and left-eye images are alternately displayed on the panel by alternately repeating right-eye fields, each of which has a plurality of subfields and displays a right-eye image signal, and left-eye fields, each of which has a plurality of subfields and displays a left-eye image signal. Each subfield has an address period for performing an address operation and a sustain period for performing a sustain operation. In a discharge cell where gradation of a predetermined threshold or higher is displayed, the address operation is prohibited in the subfield disposed last in the field.

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.
