摘要： Image display quality in the plasma display apparatus can be enhanced by allowing a stable address operation. For this purpose, the plasma display apparatus includes a scan electrode driver circuit. The scan electrode driver circuit generates driving voltages to be used in a subfield method and applies the driving voltages to scan electrodes. At the end of each sustain period, the scan electrode driver circuit performs the following operation. The scan electrodes are applied with a first ramp waveform voltage that rises from a base electric potential to a first electric potential. Subsequently, the electric potential of the scan electrodes is set to a second electric potential equal to or lower than the first electric potential. Subsequently, the scan electrodes are applied with a second ramp waveform voltage that rises from the second electric potential to a third electric potential higher than the first electric potential.

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 the plasma display apparatus, accidental discharge is prevented from occurring in a second discharge cell. For this purpose, in driving a plasma display panel having first data electrodes and second data electrodes that are arranged in parallel with the first data electrodes in a region outside the region where the plurality of first data electrodes are arranged, first voltage is set to be higher than second voltage in at least one subfield. Here, it is assumed that the first voltage is the voltage derived by subtracting the voltage applied to the first data electrodes from the voltage applied to the second data electrodes when down-ramp waveform voltage is applied to scan electrodes in the initializing period, and the second voltage is the voltage derived by subtracting the low-voltage-side voltage of the address pulse applied to the first electrodes from the voltage applied to the second data electrodes in the address period.

摘要： A stable address operation is performed also when a plasma display panel having a high definition and large screen is driven. For this purpose, a driving method of a plasma display panel is provided. The panel is driven by forming one field using a plurality of subfields each of which has an address period and a sustain period in which sustain pulses varying from a base potential to a voltage at which a sustain discharge is caused in the discharge cell having undergone the address discharge are applied to the display electrode pairs. In the driving method, after generation of the final sustain pulse in the sustain period, an up-ramp waveform voltage which increases from the base potential to a predetermined voltage is applied to the scan electrodes. The predetermined voltage is set lower than the voltage of the sustain pulses.

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. In the selective initializing subfield, based on the load calculated in the address period of the immediately preceding subfield, the minimum voltage of the down-ramp waveform voltage is controlled.

摘要： Sharp contrast is achieved while the driving time in displaying a 3D image on a plasma display panel is shorted. For this purpose, an all-cell initializing subfield for applying up-ramp waveform voltage and down-ramp waveform voltage to a scan electrode in the initializing period is set as the first subfield of one field. The plasma display panel is driven by one of 3D drive and 2D drive. A gradient of at least one of the up-ramp waveform voltage and the down-ramp waveform voltage in the all-cell initializing period during the 3D drive is set to be steeper than a gradient of the one waveform voltage in the all-cell initializing period during the 2D drive. A shutter opening/closing timing signal is generated so that both of a right-eye timing signal and a left-eye timing signal are in the OFF state in the all-cell initializing period during the 3D drive.

摘要： In display of a 3D image on a plasma display panel, the plasma display apparatus achieves an excellent contrast with reduced crosstalk. For this purpose, the plasma display apparatus includes a driver circuit and a control signal generation circuit. The driver circuit drives the plasma display panel in a manner such that a subfield where an all-cell initializing operation is performed in the initializing period and a sustain discharge is caused in all the discharge cells in the sustain period is set as the first subfield of one field. The control signal generation circuit generates shutter opening/closing timing signals that include a timing signal for the right eye and a timing signal for the left eye.
