Abstract
Driving Waveform of AC PDP in reset periode is increased and decreased with constant slope to improve dark room contrast ratio and image quality. But the slope and magnitude of ramp waveform are related to strong and weak discharge with temperature change in AC PDP. So this paper proposes a methods of changing the slope and magnitude of ramp waveform during reset periode according to temperature change in AC PDP. Experimental variable factors ire chosen to setup slope, setdown slope, and -Vy voltage magnitude in Y sustain electrode. The proposed methods are expected to compensate for effect of the temperature change, causing misfiring in high and low temprature, with varing the slope and magnitude of ramp voltage during reset period and improve image quality.
