Abstract:
1. A method of providing a grey level in a plasma display panel, the plasma display panel having a first substrate and a second substrate arranged to face each other, a plurality of sustaining electrode pairs formed on the first substrate in a first direction, a plurality of address electrodes formed on the second substrate in a second direction, which is different from the first direction, and a plurality of cells being formed where the plurality of sustaining electrode pairs cross the plurality of address electrodes, the method comprising: selecting at least one cell during an address period of at least one sub-field; and applying only one sustain pulse to a first electrode of a sustaining electrode pair and not applying a sustain pulse to a second electrode of the sustaining electrode pair during a sustain period of the at least one sub-field, wherein the only one applied sustain pulse causes only one sustain discharge to occur within the at least one selected cell during the sustain period of the at least one sub-field, and wherein the only one sustain discharge is caused by a potential difference for a prescribed period of time between the first electrode of the sustaining electrode pair of the at least one selected cell and the second electrode of the sustaining electrode pair of the at least one selected cell during the sustain period of the at least one sub-field.
