Method for fabricating ribs of a plasma display panel
A method for fabricating a rib on a glass substrate includes steps of printing a first paste layer on the glass substrate, printing a second paste layer onto a first predetermined area of the first paste layer and the second paste layer having a hardener, activating the hardener of the second paste layer to harden the second paste layer, performing a stripping process to remove a portion of the first paste layer uncovered by the hardened second paste layer, and sintering the remaining first paste layer and the second paste layer to form the ribs. The first paste layer is formed by a solid printing process and the second paste layer is formed by a screen printing process. The second paste layer is a rib material having a photo-active hardener, such as polyvinyl cinnamate. The hardener of the second paste layer is activated by an exposure process. Finally, the hardener is removed from the second paste layer in the sintering process and the first paste layer is fused to the second paste layer. and the ribs are formed.
