Abstract:
1. A plasma display panel drive method of driving a plasma display panel for each of a plurality of subfields constituting a single field of an image signal, the plasma display panel including a plurality of picture elements, each picture element being constituted by a plurality of discharge cells with differing emission colors, the plasma display panel drive method comprising: an address step that sets each of said discharge cells to either a lit discharge cell state or an extinguished discharge cell state by selectively causing said discharge cells to discharge in accordance with said image signal; and a sustaining step that causes only said discharge cells in said lit discharge cell state to have a specific number of sustain discharges corresponding to said subfields; wherein said plasma display panel drive method further includes a reset step that initializes, for at least one of said subfields, all the discharge cells thereof to either said lit discharge cell state or said extinguished discharge cell state by causing all the discharge cells to continuously have a specific number of reset discharges prior to said address step; wherein the number of said reset discharges caused in said discharge cells that handle light emission in at least one emission color in said picture element is, in at least one of said reset steps in said field, or in said reset steps in one field of a plurality of fields, greater than the number of said reset discharges caused in said discharge cells that handle light emission in other colors.
