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： 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. The control signal generation circuit sets both of the timing signal for the right eye and the timing signal for the left eye to OFF in the period of the first subfield.
