Abstract :
A new asymmetric variable-width scan waveform is proposed to improve the characteristics of an address discharge, including a reduced address time and increased dynamic voltage margin, based on the formative and statistical time lags of an address discharge in an ac-plasma display panel (ac-PDP). The new asymmetric variable-width scan waveform has a progressively increasing scan pulsewidth that is wider than the address pulsewidth, thereby enabling stable wall charge accumulation under short address pulsewidth conditions. When adopting this new scan waveform, the address pulsewidth was reduced from 3.0 to 1.4 μs and the address voltage lowered from 65 to 55 V without any misfiring problem at an address pulsewidth of 1.4 μs.
