  • Patent number: 6867552
    Abstract: After a sustain discharge period, a voltage twice a sustain pulse is applied to one of sustain discharge electrodes to form, on an address electrode, wall charges capable of self-erase discharge between an address electrode and the sustain discharge electrode by an address pulse, and the address pulse is applied to the address electrode to perform self-erase discharge between the address electrode and the sustain discharge electrode, thereby removing the wall charges formed on the address electrode. With this arrangement, a cell to be turned on in accordance with display data can be accurately selected in an address period without forming any wall charges on the address electrode, and any degradation in drive margin or display quality of a plasma display device can be suppressed.
