Abstract

Because the plasma display panel has used red, green and blue(RGB) phosphors, it has suffer from two intrinsic problems; 1) the cell defect due to the lack of binding force between phosphor particles and 2) mis-discharge because of difference of electrical characteristics among RGB phosphors. In order to control the mechanical and electrical properties of RGB phosphors, frit with $ZnOB_2O_3-SiO_2-Al_2O_3$ system was added to RGB phosphor as sintering additive. The mechanical properties were increased by the amount of frit. The amount of frit under 5 wt% rarely affected dielectric constant. However, there was the limit of amount because of decreasing optical properties seriously; over 3 wt% in red, over 10 wt% in green and blue.
