DRIVING METHOD FOR PLASMA DISPLAY PANEL, AND PLASMA DISPLAY DEVICE

摘要

In order to improve the contrast of a display image and stably generate write discharge in a plasma display device, either a forced initialization operation for generating initialization discharge in a discharge cell or a selective initialization operation for selectively generating initialization discharge in discharge cells in which write discharge has been generated in an immediately preceding subfield is performed in an initialization period. A specific cell initialization subfield having an initialization period in which the forced initialization operation is performed in a specific discharge cell and the selective initialization operation is performed in the other discharge cells is provided in one field. In the discharge cell in which the selective initialization operation has been performed in the initialization period of the specific cell initialization subfield, the period during which a scan pulse and a write pulse are simultaneously applied to the discharge cell in the write period of the specific cell initialization subfield is made longer than that in the discharge cell in which the forced initialization operation has been performed in the initialization period of the specific cell initialization subfield.
