摘要： An unnecessary discharge caused in the discharge cells in an initializing operation is prevented. This reduces the luminance of black level in a display image and stabilizes the address discharge at the same time, thus enhancing the image display quality. A plasma display panel that has a plurality of discharge cells having data electrodes and display electrode pairs, each formed of a scan electrode and a sustain electrode, is driven for gradation display such that a plurality of subfields is set in one field and each of the subfields has an initializing period, an address period, and a sustain period. For the above purpose, in the driving method for the plasma display panel, the following operations are performed. In the address period of a predetermined subfield, after the application of a scan pulse to all the scan electrodes is completed, a ramp voltage gently falling from a first voltage is applied to the sustain electrodes. In the period during which the falling ramp voltage is applied to the sustain electrodes, a second voltage is applied to the data electrodes.

摘要： In a former half (T11) of an all-cell reset period (T1), the potential of a scan electrode (Scn) is raised from 0 [V] to Vp [V] at a timing t0, and thereafter maintained at the positive potential of Vp [V] to Vg [V] until a timing t3 when the former half (T11) ends. On the other hand, in the same former half (T11), a reset pulse (Pul.2), which includes a negative ramp waveform portion from 0 [V] to a potential of Vr [V], is applied to a sustain electrode (Sus). A time period (t1−t0) of the negative ramp waveform portion of the pulse (Pul.2) is set longer than a time period required for the potential change of a pulse (Pul.1) from P1 to P2.
