GLASS FRIT COMPOSITIONS FOR BARRIER RIBS OF PDP

摘要

A PbO-free glass frit composition for barrier ribs of PDP is provided to obtain lighter glass frit, which is calcinated at relatively low temperature and is easily subjected to etching process, and to have excellent hardness and elasticity coefficient. A PbO-free glass frit composition for barrier ribs of PDP comprises 80-85wt% of glass frit and 15-20wt% of filler. The glass frit comprises: main ingredients consisting of 40-50wt% of Bi2O3, 25-41wt% of ZnO and 15-25wt% of B2O3; and sub ingredients consisting of 0.5-11wt% of at least one compound selected from BaO, K2O, Al2O3 and SrO. The filler comprises at least 10 wt% of ZnO and at least 5wt% of Al2O3.
