Effects of Gas Pressure on Temporal Image Sticking in AC Plasma Display Panel

Abstract

The temporal dark and bright image sticking phenomenon was examined under various gas pressures in a 42-in. ac-PDP with an He(35%)-Xe(11%)-Ne gas composition. To study the temporal dark and bright image sticking phenomena for various gas pressures, the displayed luminance, IR emission profile, disappearing time, color temperature, panel temperature, and Xe and Ne ions density of temporal dark and bright image sticking were measured relative to the gas pressure. With a decrease in the gas pressure, the temporal bright image sticking was observed to be reduced due to the reduction of the ion bombardments onto the phosphor layer.
