PLASMA DISPLAY PANEL DRIVE METHOD

摘要

A plurality of subfields constituting a 1-field period includes a subfield performing all-cell initialization operation for generating initialization discharge at all the discharge cells during an initialization period and a subfield performing selected initialization operation for generating initialization discharge at a predetermined discharge cell during the initialization period. In at least one low-gradation subfield, all-cell initialization operation is performed. Following the subfield performing the all-cell initialization operation, a low-gradation subfield is arranged. During the duration period of the subfield performing the all-cell initialization operation or the low-gradation subfield, the width of the first maintaining pulse (P1) is set greater than the width of the second maintaining pulse (P2) and the width of the second maintaining pulse (P2) is set greater than the width of the third maintaining pulse and after. With this configuration, it is possible to suppress brightness caused by erroneous discharge, thereby providing a plasma display panel drive method capable of displaying an image with a high quality.
