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.

摘要翻译：要解决的问题：为了防止显示单元由于等离子体显示面板的相邻显示单元之间的串扰而错误地工作，并且还防止图像质量劣化。解决方案：通过两个复位脉冲P1和P2形成全表面复位脉冲。在复位脉冲P1的上升期间产生的放电定时D11和D21根据作为放电空间的某个单元的情况而变化。然而，在随后的自擦除放电D12和D22中，几乎在相同的定时产生放电。施加第二复位脉冲P2以在单元中再次放电，从而几乎同时在所有单元中由第二复位脉冲P2产生写入放电D13和D23，换句话说，放电延迟的不均匀性（方差）减小。因此，减小了上下邻接显示单元之间的电荷的影响（串扰），并且在随后的寻址周期中可靠地确保正常的地址放电。版权所有（C）2010，JPO＆INPIT
