Abstract
This paper describes a novel waveform which improved the luminous efficiency of AC-PDP without reducing the voltage margin. This waveform, which induces self-erase discharges by space charges, utilizes the memory effect of space charges like the pulse memory of DC-PDP, in addition to the memory effect of wall charges. More than a 15% higher efficiency is obtained in the 40-inch diagonal XGA AC-PDP developed by us when compared with the conventional waveform at the same operating point.
