Effect of full-white aging discharge on recovery of boundary image sticking in AC-PDP

When displaying the square-type image with peak luminance for a long time in 42-in. PDP-TV, the permanent image sticking and boundary image sticking appeared This image sticking phenomenon is deeply related to the Mg species sputtered from the MgO surface of the discharge cell due to the iterant strong sustain discharge. In particular, the boundary image sticking is due to the re-deposition of the Mg species on both the MgO and phosphor layers in the non-discharge region adjacent to the discharge region. To reduce the boundary image sticking, the effects of full-white aging discharge on the boundary image sticking were observed The full-white aging experiment showed that the MgO morphology in the boundary region was changed due to the 100 hours full-white aging discharge, which was almost similar to that in the non-discharge region. Furthermore, the changes in the discharge and luminance characteristics in the boundary image sticking region were observed after the 100 hours full-white aging discharge. As a result, it is observed that the full-white aging discharge can contribute to reducing the boundary image sticking considerably.
