Abstract:
A method of driving an AC plasma display panel for displaying a picture including gray scale images comprising:dividing a horizontal synchronization period into a plurality of sub-periods;sequentially applying different numbers of discharge sustaining pulses to first and second electrodes of the AC plasma display panel the AC plasma display panel having an n matrix with k rows and n columns, k pairs of first and second electrodes parallel to each other and located on a first substrates, and n third electrodes perpendicular to the first and second electrodes and located on a second substrate, the second substrate being parallel to the first substrate, wherein the second electrodes are common electrodes and are grouped into p common wiring groups, the first electrodes are scanning electrodes, and the third electrodes are address electrodes;setting address time slot periods in a period between discharge sustaining pulses and applying a plurality of data pulses to an address electrode during the respective address time slot periods; andsequentially selecting the common wiring groups to correspond to the plurality of data pulses and sequentially applying scanning pulses corresponding to the plurality of data pulses, the plurality of data pulses corresponding to the common electrodes of selected common wiring groups.
