Driving method of AC-type plasma display panel

摘要

A method for driving an alternating current (AC) plasma display panel is provided which is capable of making sustaining light emission inconspicuous caused by erroneous discharge during a period when supply power becomes stable even if erroneous discharge occurs due to an influence of residual charges produced at a time of starting operations of the AC plasma display panel. A driving method for one frame is changed between a period (supply power stability waiting period) required until the supply power becomes stable and a display period. Time required until a voltage becomes stable is for example 0.5 seconds to 1 second after power-ON. In a field during this period, one field is divided into a plurality of sub-fields and the number of repeated pulses is smaller during a sustaining period of each sub-field than that of repeated pulses during a sustaining period of a sub-field in the display period. For example, no sustaining pulse is fed to a scanning electrode. As a result, sustaining light emission becomes inconspicuous even if the erroneous discharge occurs due to an influence of the residual charges.
