Control of initial wall charges for multi-luminance of an AC plasma display panel

A new driving waveform is proposed to control the initial wall charges for multi-luminance during the reset-period. The luminance levels are measured based on the variation in the initial wall charge under a constant sustain pulse condition in an AC Plasma Display Panel cell. To control the initial wall charges, We applied an auxiliary address pulse during wall charge generation and redistribution parts in the reset-period. As a result, we observed that the luminance levels could be varied under the same sustain pulse conditions within a luminance level ratio of one or two in the case of different initial wall charge conditions.
