    • A plasma display device that enables a stable address operation even in a high-speed drive so as to display an image of high definition and high quality. A PDP having discharge cells each provided with a scanning electrode and a sustaining electrode is driven by a method for displaying a frame of an image by repeating an address period, a discharge sustaining period, and a discharge suspend period. At least one initialization period that succeeds a discharge suspend period and in which the state of the wall charge in each discharge cell is initialized is provided. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period.

    • It is an object of the present invention to provide a plasma display apparatus in which reliable erase discharge is performed and an erroneous discharge is suppressed, even when a discharge sustain period is shortened so as to realize a PDP having high definition.The above object is achieved in the following manner. In the discharge sustain period, a pulse applied in the later part of the discharge sustain period has a larger pulse width than a pulse applied in the earlier part of the discharge period, except for an initial pulse in the discharge sustain period. In addition, a called narrow pulse is applied in an erase period to perform an erase discharge. According to this method, wall voltages in discharge cells at the end of the discharge sustain period are raised to a higher level than in the related art. As a result, reliable erase discharge is performed, and an erroneous discharge is suppressed.
    • 本发明的目的是提供一种等离子体显示装置,其中即使在放电维持期被缩短以便实现具有高清晰度的PDP的情况下,也可以进行可靠的擦除放电并且抑制误放电。 上述目的以下述方式实现。 在放电维持期间,除了放电维持期间的初始脉冲以外,在放电维持期间的后期施加的脉冲的脉冲宽度比在放电期间的较早部分施加的脉冲宽。 此外,在擦除周期中施加所谓的窄脉冲以执行擦除放电。 根据该方法,将放电维持期结束时的放电单元中的壁电压提高到比现有技术更高的水平。 结果,执行可靠的擦除放电,并且抑制了错误的放电。
