Abstract
In a low voltage operation method of a PDP (plasma display panel) and an apparatus thereof capable of maintaining a picture quality and operation efficiency although a minimum operation voltage is applied to a PDP, the low voltage operation method of the plasma display panel includes operating one frame by dividing it into several sub-fields in order to obtain a gray level of a PDP, dividing the sub-field into a reset period, an address period, a sustain period and supplying a ramp waveform in the reset period, and applying a DC biasing voltage in order to reduce wall electric charge discharged in descending of the ramp waveform.
