ABSTRACT:
A plasma display driving method and apparatus for stabilizing an initialization upon selective erasing in a case of simultaneously performing a selective writing and a selective erasing is disclosed. In the method and apparatus, at least one selective writing sub-field for selecting on-cells using a writing discharge is arranged within a portion of one frame period, and at least one selective erasing sub-field for selecting off-cells from the on-cells using an erase discharge is arranged within the remaining interval of one frame period other than a time period arranged with the selective writing sub-field. A normal sustaining pulse is applied to the selected on-cells to sustain a discharge of the on-cells, and an initialization pulse having at least one of a pulse width and a voltage level set to be larger than the normal sustaining pulse is applied prior to said selective erasing sub-fields.
