Effect of Additives on Transmittance of Tick Film Prints in PDP

Glass frits for dielectric layers are mostly used for screen printing process. Several additives have already been known to be well matched with lead-oxide glasses system. The use of lead oxide, however, creates environmental problems, so many recent studies on lead-free glasses compositions have been carried out. A study of the suitability between additives and lead-free glass system is needed. In this study, we have used a screen-printing method to make thick films of lead-oxide glass and lead-free glass using different additives, and analyzed and compared the transmittance of the thick films.
