    • In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.
    • 在具有三个电极(X,Y,A)的PDP的显示单元中使用触发放电的长距离放电中,提供了能够通过使用浮动电极以低功耗稳定地产生触发放电的技术。 在PDP的电介质层中,在第一和第二显示电极之间形成长间隙,形成与第一和第二显示电极电容耦合的第一和第二浮子电极,并且在第一和第二显示电极之间形成短间隙 第二浮球电极。 维持脉冲施加到第一和第二显示电极,从而在短间隙中产生小的触发放电。 在该放电之后,产生长间隙的主放电。 电极和电容被构造成使得主放电具有等于或小于触发放电强度的五分之一的强度。

    • In a plasma display device comprising: plural first, second, and third electrodes disposed adjacently and extending in a first direction, the third electrodes being provided between the first and second electrodes for repeating discharges; a dielectric layer covering the electrodes, a first electrode driving circuit for driving the first electrodes; a second electrode driving circuit for driving the second electrodes; and a third electrode driving circuit for driving the third electrodes, grayscale display is performed by a sub-field method, and the third electrodes are set to have a potential approximately the same as that of the first or second electrode at the discharge in the repetitive discharges. The third electrode driving circuit changes the ratio of the discharges in which the third electrodes operate as cathodes to the discharges in which they operate as anodes in the period when the discharges are repeated, at least in one sub-field.
