ABSTRACT:
A method for driving an address-display separated-type AC (Alternating Current) PDP (Plasma Display Panel) is provided which is capable of having sequentially and continuously wall charges be formed sufficiently on a scanning electrode and sustaining electrode even when a width of a scanning pulse is shortened. Driving operations of a scanning driver and sustaining driver for the scanning electrode and the sustaining electrode during a pre-discharge period are the same as those employed in the conventional method. Driving operations for the scanning electrode during a scanning period are also the same as those in the conventional method except following. At ending time of a period during which a scanning pulse is applied to the scanning electrode, a potential difference obtained by superimposing a writing wall charge forming pulse on a sustaining pulse is applied for 3 μsec to 5 μsec. At an ending time of the application of the potential difference, wall charges having amounts larger than those achieved by the conventional method can be accumulated on the scanning electrode and the sustaining electrode.
