摘要： An object of the present invention is to display an image with a good image quality when driving a PDP, by stabilizing an initialization operation to suppress a false discharge when a writing operation is performed.Therefore, in a method of driving a PDP of the present invention, one TV field is composed of a plurality of subfields each including an initialization period (31), a writing period (32), a sustain period (33), and an elimination period (34).When an immediately preceding subfield does not include the sustain period (33), a priming pulse (Vpr) is applied to address electrodes (D1 to Dm) prior to a ramp waveform part (S1) of an initialization pulse applied to scan electrodes (SCN1 to SCNn), after the writing operation ends. When the immediately preceding subfield includes the sustain period (33), the priming pulse (Vpr) is applied to the address electrodes (D1 to Dm) prior to the ramp waveform part (S1), after the sustain period ends.

摘要： During each set-up period, wall charges of scan electrodes and sustain electrodes, between which sustain discharges were generated in the previous subfield, are adjusted, and parts toward the sustain electrodes of positive charges in the scan electrodes are replaced by negative charges and parts toward the scan electrodes of negative charges in the sustain electrodes are replaced by positive charges. During each address period, write pulses are applied to the scan electrodes to generate write discharges utilizing priming discharges between the scan electrodes and priming electrodes. During each sustain period, positive charges are accumulated in the entire surfaces of the scan electrodes and negative charges are accumulated in the entire surfaces of the sustain electrodes.

摘要： Barrier ribs are disposed on a back substrate so as to separate main discharge cells formed of a display electrode pair and a data electrode which face each other and priming discharge cells formed of a clearance between two adjacent scan electrodes. The top parts of the barrier ribs are formed so as to abut on a front substrate. In a driving method, in an odd-numbered line writing time period, scan pulse Va is sequentially applied to odd-numbered scan electrode SCp and voltage Vq is applied to even-numbered scan electrode SCp+1 to cause priming discharge between scan electrode SCp+1 and odd-numbered scan electrode SCp. In an even-numbered line writing time period, scan pulse Va is sequentially applied to even-numbered scan electrode SCp+1 and voltage Vq is applied to odd-numbered scan electrode SCp to cause priming discharge between scan electrode SCp and even-numbered scan electrode SCp+1.

摘要： In a driving method of a plasma display panel of the present invention, plural display electrode pairs are divided into plural display electrode pair groups and one field is divided into plural sub-fields. The length of the sustain period is compared to the length of the erase period. If the sustain period is longer than the erase period, sustain discharge and erase discharge are performed for each of the display electrode pair groups, while if the sustain period is shorter than the erase period, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group. For a sub-field with a largest luminance weight or a sub-field with a highest lighting ratio, sustain discharge and erase discharge of one display electrode pair group are synchronized with those of another display electrode pair group without fail.
