ABSTRACT
When displaying a square-type image with peak luminance for approximately 500 h in a 42 in. plasma display panel TV with high Xe (15%) content, halo-type boundary image sticking was observed in the nondischarge region adjacent to the discharge region. The halo-type boundary image sticking phenomenon is due mainly to the redeposit of the Mg species on the MgO layer in the nondischarge region adjacent to the discharge region, which is verified by measuring the redeposited Mg species in the boundary image sticking region using a cross-sectional scanning electron microscope. Based on this result, three kinds of solution to remove the boundary image sticking of an ac plasma display panel are introduced. First, we completely recover the boundary image sticking cells by using a full-white aging process. Second, we prohibit the inherent production of boundary image sticking by sealing the plasma display panel under vacuum. The final solution is to prohibit the inherent production of boundary image sticking by use of lower gas pressure.
