摘要： PROBLEM TO BE SOLVED: To prevent display cells from erroneously functioning due to crosstalk between the adjoining display cells of a plasma display panel, and also to prevent image quality from being degraded.
SOLUTION: A full surface reset pulse is formed by two reset pulses P1 and P2. The timing of electric discharges D11 and D21 generated at rising of the reset pulse P1 varies depending on a situation of a certain cell which is a discharge space. In subsequent self-erasure electric discharges D12 and D22, however, electric discharges generates almost at the same timing. A second reset pulse P2 is applied to discharge electricity again in the cell, thereby generating write electric discharges D13 and D23 by the second reset pulse P2 in all the cells almost simultaneously, in other words, nonuniformity (variance) in discharge delay is reduced. Thus, the influence (crosstalk) of charges between the upper and lower adjoining display cells is reduced, and normal address electric discharging is surely secured in a subsequent address period.
