Abstract
A novel method for driving a plasma display panel and a plasma display device for reducing background emission due to a reset discharge are disclosed. In a three-electrode type PDP, a third (Z) electrode is provided between a first (X) electrode and a second (Y) electrode between which a discharge is caused to occur and when a reset discharge is caused to occur, the third electrode is set to a potential that makes the third electrode function as an anode for the electrode used as a cathode during the reset discharge between the first and second electrodes.

A method for driving a plasma display panel comprising:
- a plurality of first and second electrodes alternately provided in parallel to each other and between adjacent electrodes of which, a repetitive discharge is caused to occur;
- and
- a plurality of third electrodes each provided between the first and second electrodes, between which the repetitive discharge is caused to occur, and covered with a dielectric layer,
- wherein regardless of display data, when a reset discharge, which is caused to occur in every cell, is caused to occur between the first and second electrodes, the third electrode is set to a potential that makes the third electrode function as an anode for the electrode used as a cathode during the reset discharge between the first and second electrodes.
