摘要： In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an address period for selectively causing address discharge in a 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. In the discharge cell for causing address discharge in a certain subfield other than the head subfield in each subfield group, address discharge is caused even in the head subfield.

摘要： The present invention provides a plasma display panel and a method for driving the plasma display panel each of which ensures to suppress problems associated with an erroneous discharge resulting from accidental occurrence of a strong discharge in a reset period as well as with an address discharge delay. The problems are suppressed without applying an auxiliary erase pulse after the reset period ends. As a result, image display is provided with no flickering and good quality. The reset period includes a first step of applying a voltage having an ascending ramp waveform and a second step of applying a voltage having a descending ramp waveform. Between the first and second steps, a potential change waveform having a rise or fall (voltage change pulse) is applied at least to scan electrodes, sustain electrodes, or address electrodes.
