摘要： In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an initializing period for causing initializing discharge in a discharge cell, an address period for selectively causing address discharge in the discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. A holding period when discharge is not caused is disposed before the head subfield belonging to at least one subfield group of the plurality of subfield groups.

摘要： In the initializing period of each of sub-fields comprising one field, one of all-cell initializing operation and selective initializing operation is performed. The all-cell initializing operation causes initializing discharge in all the discharge cells for displaying an image. The selective initializing operation selectively causes initializing discharge only in the discharge cells subjected to sustaining discharge in the preceding sub-field. Provided in the all-cell initializing period is an abnormal charge erasing part in which application of a rectangular waveform voltage to the scan electrodes causes self-erasing discharge in the discharge cells having excessive wall voltage accumulated therein.
