PURPOSE:To prevent erroneous discharge by providing a write period immediately after a priming period, providing a charge inversion period and making a wave crest value of a voltage pulse in a maintenance period of a scanning electrode side smaller than that of a maintaining electrode side. CONSTITUTION:The scanning electrode and the maintaining electrode are discharged in the priming period, and succeedingly, the voltage pulsed is applied to the maintaining electrode in the charge inversion period to generate the discharge between the maintaining electrode and the scanning electrode, and to invert the polarity of the charge on the scanning electrode. Succeedingly, the voltage pulse is applied to the scanning electrode successively in the write period, and the voltage pulse synchronizing with the pulse is applied to a data electrode according to the display data to generate the discharge between the data electrode and the scanning electrode, then the discharge is maintained between the scanning electrode and the maintaining electrode in the maintaining period, and the discharge of the maintaining electrode is maintained for a required period in an erasure period, thereafter the data are erased. In the maintaining period, an amplitude of a maintaining pulse 2 of the same phase as a write pulse is made larger, and on the other hand, the amplitude of the maintaining pulse 1 with the antiphase to the write pulse is made smaller. |
