An experimental observation on the effect of oxygen and nitrogen gas addition on the image retention in an AC plasma display panel

In this paper, the effect of oxygen and nitrogen gas addition to the Ne-Xe mixture discharge gas on the various kinds of image retention was investigated in 42-inch AC Plasma Display Panels. The image retentions were dramatically relieved with a small amount of molecular gas addition. It was observed that the temporal variation of the reset threshold voltage induced by discharge heat-run can be suppressed by adding a small amount of molecular gases to the discharge gas. Both residual gas and cathodoluminescence analyzes showed that the added molecular gases could be incorporated in MgO surface during the discharge. With the investigation on the feasibility, we suggest that a small amount of nitrogen gas addition is suitable for the relief of image retentions which can be adapted in industry.
