Summary:Misfiring is often observed during the high-temperature quality assurance test of plasma display panels. This limits the productivity of the plasma display panel industry. In this paper, experimental observations on the misfiring at high-panel temperatures have been performed through time-dependent discharge light output and static margin measurement. For the high-temperature condition, the firing voltage increment is found in both surface and facing discharges. This in turn increases time lag in address discharge, and results in increment of misfiring probability. In order to reduce this kind of misfiring, a modified method that applies automatically to a different slope of ramp erase pulse on the sustain electrode according to temperature variation is proposed. The experimental results show that controlling the slope of the ramp erase pulse is quite effective for compensating the temperature-dependent variation of reset and address discharge.
