Fabrication and characterization of dielectric materials of front and back panel for PDP

Abstract The glass compositions of PbO‐SiO2‐B2O3 system and P2O5‐PbO‐ZnO system for the transparent dielectric materials for front panel and P2O5‐ZnO‐BaO and SiO2‐ZnO‐B2O3 for the reflective dielectric materials for back panel of PDP (Plasma Display Panel) were investigated. As a result, transparent dielectric materials for front panel showed good dielectric properties, high transparency, and proper thermal expansion matching to soda lime glass substrate. And the reflective dielectric layers for back panel were prepared from two series of parent glass and oxide filler. It was found that these glass‐ceramics are useful materials for dielectric layers in PDP device, as they have similar thermal expansion to soda‐lime glass plate, high reflectance, and low sintering temperature. In particular, the addition of BPO4 and TiO2 as fillers to SiO2‐ZnO‐B2O3 system is considered to be the most effective for acquiring good properties of lower dielectric layer for PDP device.
