Design of Erase-Addressing Scheme on PDP According to the Number of Sustain Pulses before addressing
Details
The multi-width scan pulse, erase-addressing scheme provides high speed and low voltage addressing. However the dynamic voltage margin is influenced by the number of sustain pulses before the addressing. In this report, the scan pulse widths were adjusted according to the number of sustain pulses for obtaining large margin. It was found that more than 19 sustain pulses are necessary when Full-HD PDP is driven with 24 contiguous-subfield, single-scan, 14 grouped AWD scheme. The width of scan pulse ranged from 0.2μs to 0.6μs with an average of 0.52μs. Driving with 3 sustain pulses is also possible when the number of groups is increased to 30 or the number of subfield is reduced to 19.
