Abstract:
1. A method of driving a plasma display selecting discharge cells using selective writing sub-fields and selective erasing sub-fields arranged within one frame period and provided with a plurality of scan electrodes, a plurality of sustain electrodes and a plurality of address electrodes, said method comprising: applying sustaining pulses to on-cells selected to sustain a discharge of the on-cells in a sustain period of at least one of the selective writing sub-fields of the one frame period; and applying an initialization pulse having at least one of a pulse width and a voltage level set to be larger than said sustaining pulses, the initialization pulse being applied in the sustain period of the at least one of the selective writing sub-fields of the one frame period prior to the selective erasing sub-fields, wherein a selective writing sub-field other than a last selective writing sub-field adjacent to said selective erasing sub-fields, of said selective writing sub-fields arranged within said one frame, includes a reset period for initializing all the cells of the plasma display, an address period for causing a sustain discharge with respect to said on-cells, and a post erase period for erasing electric charges left within the discharge cells.
