摘要 |
A first ramp waveform (RW1) rising from a first potential (Vscn) to a second potential (Vscn+Vset) is applied to a plurality of scan electrodes (SCi) in a first period (t5 to t6), and a driving waveform dropping from a third potential (Ve1) to a fourth potential (0V) is applied to a plurality of sustain electrodes (SUi) before the first period (t5 to t6), and the plurality of sustain electrodes are held at the fourth potential (0V) in the first period (t5 to t6). At this time, a second ramp waveform (RW10) rising from a fifth potential (0 V) to a sixth potential (Vd) according to change of a potential of the first ramp waveform (RW1) is applied to a plurality of data electrodes (Dj) in a second period (t5 to t5a) that starts at a starting time point (t5) of the first period (t5 to t6) and is shorter than the first period (t5 to t6), thereby preventing generation of strong discharges between the plurality of data electrodes (Dj) and the plurality of scan electrodes (SCi).
