Plasma display panel and apparatus with adjustment of the number of sustain pulses in selected subfields for flicker reduction, and driving method and device for the same

摘要

A plasma display apparatus which comprises a plasma display panel comprising a scan electrode and a sustain electrode. A sustain pulse controller sets the number of sustain pulses applied to the scan electrode or the sustain electrode per unit gray level in the sustain period of a lower gray level subfield of a subfield group to be greater than the number of sustain pulses of the other subfield in the frame. The use of a plurality of subfields reduces flicker, particularly where 50Hz PAL signals are to be displayed.
