DRIVING METHOD FOR PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE

PROBLEM TO BE SOLVED: To reduce the number of times of forced initialization operations of a plasma display panel to suppress black luminance and to perform a stable writing operation.SOLUTION: In a driving method for a plasma display panel, a field includes: a first kind of subfield in which a scanning electrode applying falling inclined waveform voltage after applying rising inclined waveform voltage rising up to prescribed voltage generating discharge, regardless of the history of discharge, and a scanning electrode applying falling inclined waveform voltage after applying rising inclined waveform voltage rising up to voltage lower than prescribed voltage exist; and a second kind of subfield applying falling inclined waveform voltage to the scanning electrodes. In an initialization period of the first kind of subfield, falling inclined waveform voltage is applied to the scanning electrodes and first voltage is applied to a data electrode. In an initialization period of the second kind of subfield, falling inclined waveform voltage is applied to the scanning electrodes, and second voltage higher than the first voltage is applied to the data electrode.
