Formation of barrier ribs via micro molding process using UV-curable paste

Abstract

In an attempt to reduce processing cost and to improve the resolution of PDPs, a micro mold transfer processing route for barrier ribs of plasma display panel was attempted. In this study, the parameters that may cause defects during the process were identified, which include the shrinkage during the UV curing process, stress due to the evaporation of organic components, and sintering shrinkage. Considering such parameters, a UV curable paste was developed and the barrier ribs of PDPs were successfully processed via the process. This work demonstrated the possibility of a build-up route in manufacturing barrier ribs of PDP.
