PLASMA DISPLAY PANEL DRIVE METHOD AND PLASMA DISPLAY DEVICE

摘要

Contrast is improved and image display quality is improved by reducing the black brightness of the image displayed on a plasma display panel. In order to achieve this, in the initialization period, any of a forced initialization waveform, a selective initialization waveform and an uninitialized waveform is applied to the scanning electrodes. Also, a single field is constituted by a special initialization subfield that selectively generates the forced initialization waveform and uninitialized waveform, and a plurality of selective initialization subfields that generate only selectively initialized waveforms. The number of times that a forced initialization waveform is applied to a single scanning electrode is once in a single field group. The uninitialized waveform is applied to the scanning electrodes on both sides of the scanning electrode to which the forced initialization waveform is applied in the special initialization subfield, by at least two special initialization subfields, namely this special initialization subfield and a starting special initialization subfield subsequent to this special initialization subfield.
