Abstract
In the reset step for initializing an amount of wall charge in each of the plurality of discharge cells that define each of the picture elements in a plasma display panel, the number of reset discharges that are caused to occur in the discharge cells that handle the emission of light of at least one color within the picture element is greater than the number of reset discharges that are caused to occur in the discharge cells that handle the emission of light of the other color(s). The plasma display panel drive method provides a stable electrical discharge effect while increasing contrast.
