Abstract
The present invention aims to provide a PDP apparatus and a driving method for the same which can improve display quality by reducing a peak value of a discharge current flowing in scan and sustain electrodes in a sustain period, without an increase in manufacturing cost. This is achieved as follows. A driving unitapplies a sustain data pulseto a plurality of third electrodes in a sustain period T. Here, a voltage waveform of the sustain data pulsestarts to rise after a voltage of each of pulsesandapplied to a pair of a scan electrode SCN and a sustain electrode SUS reaches a predetermined level. Furthermore, the sustain data pulserises at a different timing at least from a sustain data pulseapplied to an adjacent data electrode.
