It is the object of the invention to provide a PDP apparatus and a driving
method that can apply pulses at high speeds and can display
high-definition, high-quality images by allowing discharge cells to emit
light with high luminance and high efficiency.To achieve the object, the
pulse has (i) a first waveform portion where a first voltage, an absolute
value of which is no smaller than a discharge start voltage, is applied
and (ii) a second waveform portion where a second voltage, an absolute
value of which is greater than the absolute value of the first voltage,
is applied, the second waveform portion following the first waveform
portion, and the second waveform portion starts before a discharge delay
time elapses from a start of the first waveform portion.Also to achieve
the object, in a PDP having an electrode structure in which each
electrode is divided into a plurality of line electrodes, the applied
pulse has (i) a first waveform portion where a first voltage, an absolute
value of which is no smaller than a discharge start voltage, is applied
and (ii) a second waveform portion where a second voltage, an absolute
value of which is greater than the absolute value of the first voltage,
is applied, the second waveform portion following the first waveform
portion.
