Influence of Ion Bombardment onto Phosphor Layer on Temporal Image Sticking in Alternating-Current Plasma Display Panel

Abstract

We found that ion bombardment onto a phosphor layer during a sustained discharge was a key factor in inducing temporal image sticking of alternating-current (AC) plasma display panels (PDPs) through facilitated absorption of H2O onto the phosphor layer. We also found that ion bombardment onto the phosphor layer during the sustain discharge strongly depended on the bias conditions of the address electrode on which the phosphor layers were deposited. As a result, the positive-biased or floated address electrode condition could minimize the ion bombardment onto the phosphor layer during the sustain discharge, thus suppressing the absorption of H2O onto the phosphor layer, and ultimately preventing temporal image sticking.
