Abstract:
A plasma generation method of a plasma display panel, the plasma display panel comprising a first substrate and a second substrate positioned in parallel with each other, an ionizable gas filled between the two substrates, and a plurality of first, second, third and fourth electrodes installed between the two substrates, the first and second electrodes being alternately installed in parallel on the first substrate, the third electrodes being installed on the second substrate perpendicular to the first and second electrodes, an area between one of the third electrodes and a pair of neighboring first and second electrodes defining a display unit for generating plasma from the ionizable gas in the display unit, each of the fourth electrodes being installed close to a neighboring first electrode, the plasma generation method comprising:step (1) charging a first predetermined voltage between the first and fourth electrodes to transform the ionizable gas in the display unit into an initial plasma; andstep (2) before the initial plasma has disappeared, charging a second predetermined voltage between the first and second electrodes for spreading the initial plasma over the display unit.
