PLASMA DISPLAY PANEL DRIVE METHOD AND PLASMA DISPLAY DEVICE

摘要

One field period includes at least one sub-field formed by at least two continuous sub-fields whose write discharge is controlled not to generate sustaining discharge in a sub-field following a sub-field not generating sustaining discharge. During the initialization period of the first sub-field of a sub-field group, it is decided whether to perform all-ell initialization or selected initialization according to the image signal displayed. The time assigned for write discharge when the selected initialization is performed during the initialization period of the first sub-field of the sub-field group is set longer than the time assigned for write discharge when the all-cell initialization is performed during the initialization period. With this configuration, it is possible to provide a plasma display panel drive method and a plasma display device capable of suppressing the increase of the black luminance and performing an image display with a preferable quality.
