摘要： A stable address discharge is caused to enhance the image display quality. For this purpose, a plasma display panel, a scan electrode driving circuit, and a partial light-emitting rate detecting circuit are provided. The scan electrode driving circuit performs an address operation by applying a scan pulse to scan electrodes in address periods. The partial light-emitting rate detecting circuit divides the display area of the plasma display panel into a plurality of regions, and detects a rate of the number of discharge cells to be lit with respect to the number of all the discharge cells in each region, as a partial light-emitting rate, in each subfield. In a predetermined subfield where the number of sustain pulses is smaller than the number of sustain pulses in the immediately preceding subfield, the scan electrode driving circuit changes the order of applying the scan pulse to the scan electrodes, according to the partial light-emitting rates in the immediately preceding subfield.

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： Plural subfields are provided in one single field period, where each subfield has an initialization period during which a gradient waveform voltage gently falling is applied to a scan electrode to generate initializing discharge in a discharge cell; a writing period during which a scan pulse voltage is applied to a scan electrode to generate writing discharge in a discharge cell; and a sustain period during which sustain discharge is generated in a discharge cell selected, by the number of times corresponding to a luminance weight. The lowest voltage of a falling gradient waveform voltage in a subfield with the smallest luminance weight is set so as to be lower than that with the largest luminance weight. A method of driving a plasma display panel is provided that generates stable writing discharge without increasing voltage required for generating writing discharge even for a large-screen, high-luminance panel.
