摘要： Stable address discharge is caused in a plasma display panel. For this purpose, the image display region of the panel is divided into a plurality of partial display regions, and scan electrodes in each partial display region are classified into two scan electrode groups based on the arranging sequence of the scan electrodes on the panel. The two scan electrode groups are a first scan electrode group including odd-numbered scan electrodes, and a second scan electrode group including even-numbered scan electrodes, In each partial display region in the address period, an overshoot address operation is performed. To the scan electrodes to which scan pulses are to be applied from the first time to a predetermined-number-th time in each scan electrode group, scan pulses are applied where the pulse cycle is set longer than that of the scan pulses to be applied to the other scan electrodes.

摘要： In a plasma display apparatus, the address discharge is stabilized, the contrast is sharpened, and the image display quality is improved. A first up-ramp waveform voltage is applied to the scan electrode, and then a voltage causing no discharge to the scan electrode is applied to the scan electrode, in the sustain period of a weak-discharge sustain operation subfield in a discharge cell that is to be subjected to a forced initializing operation in the initializing period of the subfield immediately after the weak-discharge sustain operation subfield. A second up-ramp waveform voltage is applied to the scan electrode after generation of the first up-ramp waveform voltage, in the sustain period of the weak-discharge sustain-operation subfield in a discharge cell that is to be subjected to a selective initializing operation in the initializing period of the subfield immediately after the weak-discharge sustain-operation subfield.

摘要： In the plasma display apparatus, address discharge is caused stably. For this purpose, one of a forced initializing operation and a selective initializing operation is performed in the initializing period. Then, one field includes a specific-cell initializing subfield having an initializing period in which a forced initializing operation is performed in a specific discharge cell and a selective initializing operation is performed in the other discharge cells. In the address period of the specific-cell initializing subfield, the period in which a scan pulse and an address pulse are simultaneously applied to a discharge cell having undergone the selective initializing operation in the initializing period of the specific-cell initializing subfield is made longer than the period in which a scan pulse and an address pulse are simultaneously applied to a discharge cell having undergone the forced initializing operation in the initializing period of the specific-cell initializing subfield.

摘要： In a plasma display apparatus, contrast is enhanced and a stable address discharge is caused. For this purpose, one of a forced initializing operation and a selective initializing operation is performed in initializing periods. A specified-cell initializing subfield and a selective initializing subfield are set in one field. In the specified-cell initializing subfield, the forced initializing operation is performed on specified discharge cells and the selective initializing operation is performed on the other discharge cells. In the selective initializing subfield, the selective initializing operation is performed on all the discharge cells. In the selective initializing period, a down-ramp waveform voltage is applied to the scan electrodes and a positive voltage is applied to the data electrodes.
