15.3: Anti-Electromigration of Lead-Free Ag/Frit Modified Address Electrodes in PDPs

We have studied on the usage reduction and anti-migration properties of newly formulated lead-Free (Bi-based) Ag/Frit modified address electrode (hereinafter VE electrode) systems in PDPs (Plasma Display Panels). It is thought that their high performance such as anti-migration and the cost-competitiveness without any loss of performance in paste, process and luminous efficacy are originated from the optimum controlling of Ag/Frit weight ratio and low specific gravity by low Ag contents, respectively. Currently, lead-free VE electrodes are being applied as main electrode materials of PDP panels fabricated by SDI photo-imageable patterning process including ultra-fine resolution models.
