Abstract

Recently, the voltage-controlled ramp (VCR) waveform has been used in the reset period prior to addressing for plasma display. In this method, if the ramp rise and fall times are significantly decreased in order to reduce the reset period, the dark room contrast ratio is decreased. To solve these problems, a modified current controlled ramp (CCR) waveform in the reset period is suggested. Experimental results for a 7-in model PDP show high contrast ratio without misfiring even for ramp rise/fall times of 20 μs. Moreover, the reset time can be reduced by about 30% compared with the VCR method under the same background luminance
