Abstract: A plasma display panel comprises a front plate disposed on the side of a viewer, a rear plate disposed in parallel and opposing the front plate, and cell barriers arranged between the front and rear plates of matrix shape or linear shape. The cell barrier is formed of a material including a phosphor. The cell barriers are formed by printing multiple times a phosphor paste containing glass frit in an overlapped manner by a screen printing method. The cell barrier is formed in another method in which a positive pattern of cell barriers are formed on the front or rear plate by using photo resist, a slurry containing a phosphor fills in portions except for the pattern of the photo resist, and the photo resist is thereafter removed to thereby form cell barriers. In the case of the cell barrier of a color display PDP, the cell barrier may be composed of a material containing phosphor of different colors each with a width corresponding to a one half width of the cell barrier.

Abstract: Picture tubes are reprocessed by heating the picture tube to at least the fusing temperature of the solder at the joint and separating the screen and the cone under the influence of gravity. This method effects a clean separation of the screen and the cone by slowly heating the aerated picture tube which is arranged, during heating, in such a way that the joint between the screen and the cone is inclined with respect to the horizontal, and displacing the screen and the cone in opposite directions.
