ABSTRACT:
There is explained a method and apparatus of driving a plasma display panel that is capable of increasing a driving margin upon a selective writing and a selective erasing in case that not only the selective writing but also the selective erasing are carried out within one frame period.A method of driving a plasma display panel that selects cells in use of selective writing sub-fields and selective erasing sub-fields arranged within one frame period and has a plurality of scanning electrodes, a plurality of sustaining electrodes and a plurality of address electrodes, according to an embodiment of the present invention includes steps of selecting an on-cell by generating a writing discharge in use of a first scanning voltage in the selective writing sub-fields; and selecting an off-cell by generating an erasing discharge in use of a second scanning voltage in the selective erasing sub-fields.
