摘要： In a plasma-display-panel driving method, a field period is divided into a plurality of sub fields, each of which has an address period for allowing discharge cells to selectively generate an address discharge and a sustain period for allowing the discharge cells having generated the address discharge to generate a sustain discharge by a number of times corresponding to a brightness weight. In the sustain period, a period for setting display electrode pairs to the base potential is disposed between the sustain pulse for causing the final sustain discharge in the sustain period and the previous sustain pulse. In a time interval corresponding to the lighting ratio of the discharge cells in the sub field after applying to the display electrode pairs a voltage for generating the final sustain discharge, a voltage for reducing the potential difference between electrodes of the display electrode pairs is applied to the display electrode pairs. Accordingly, it is possible to generate a stable address discharge and thus to reduce a crosstalk without increasing the voltage for generating the address discharge.

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.
