Advanced Glass Substrates For Flat Panel Displays

A current focus of precision flat glass producers is on the development of new glass compositions for use in flat panel displays. This is being done in response to requests from device manufacturers whose products and/or processes are making new demands of the substrates. Today, there are numerous glass compositions used in flat panel displays. They range from soda-lime glass, where the low cost has kept it as the substrate of choice for applications with low material demands, to fused silica, the use of which, to date, has been limited by manufacturing issues. This paper reviews the ongoing development of new glass substrates.
