Abstract

A full-white aging discharge process is proposed to recover permanent boundary image sticking in an ac plasma display panel. A simultaneous 100-h aging discharge in both boundary image sticking and nonimage sticking cells induced sputtering and redeposition of the MgO surfaces in both cell types, resulting in similar MgO surface morphologies. The luminance characteristics, including the infrared emission and chromaticity coordinates, of the boundary image sticking cells were also compared to those of the nonimage sticking cells. As a result, the full-white aging discharge was found to contribute to the recovery of permanent boundary image sticking cells.
