The Vacuum In-Line Sealing Process for High Efficiency PDP

The effects of the base vacuum level on a plasma display panel (PDP) produced by the vacuum in-line sealing technology were investigated. The main equipment of the vacuum in-line sealing process consists of the sealing chamber, pumping systems for evacuating, mass flow controller for introducing the plasma gases, and other measuring systems. During the sealing process, the impurity gases were fully evacuated and the panel was prevented from the adsorption of impurity gases. As a result, the brightness increased as the impurity gas density decreased, so we found that the vacuum in-line sealing process was more efficient technology an the conventional sealing process.
