Patent abstract
A plasma display panel and a method thereof is described. A frequency of a sustain pulse varies according to a screen load ratio in each subfield or frame. The frequency of the sustain pulse is determined such that power consumption of the plasma display panel, which is a function of the active power and the reactive power of the sustain pulse, is minimized. When the screen load ratio is increased, the frequency of the sustain pulse is increased since the decrease of the active power is increased and the reactive power is maintained.
