The invention discloses a wall electric charge in a recovery period of an erasing period of a groove type plasma display according to the characteristic of phase discharge by two electrodes in existing groove type plasma display, which forms an electric field by applying a pulse voltage via a rear basal plate addressing electrode (electrode A), generates impact on a display unit of the groove typeplasma display in the recovery period, eliminates the impact of wall electric discharge accumulated in an ignited unit in a front sub-field and ensures each discharge unit in the full screen to accumulate to a status irrelevant to previous display status. Therefore, the invention further enhances the reliability and display quality of the groove type plasma display panel and realizes the object of making the groove type plasma display panel the display of next generation.
