ABSTRACT:
A plasma display panel (PDP) includes M address electrodes, N scan electrodes and N common electrodes orthogonal to the M address electrodes. The present invention is to provide with a common driving circuit for providing the N scan electrodes with a driving voltage. During a discharge sustain period of the PDP, the discharge sustain pulses pass through only essential function means rather than unnecessary function means in the common driving circuit, and thereby unnecessary power consumption occurring in the common driving circuit can be avoided. Low power consumption in the common driving circuit can reduce the heat accumulation in the PDP to assure the display quality of the PDP and alleviate the design regarding heat sink for the PDP.
