Abstract
Back ground emission of AC-PDP deteriorates picture quality such as contrast ratio. Back ground emission occurs at a set-up period in which all pixels are activated to form initial wall voltage. Wall voltage input-output (WVIO) curve was studied for color AC-PDP to optimize a set-up waveform for low back ground emission. It was found that a ramp waveform slower than 7.5V/us reduces the back ground emission to the level of less than 10% of the conventional waveform. A42" panel with contrast ratio of 550 : 1 was commercialized using the ramp waveform.
