This post is very interesting both in terms of strategic aspect and technical aspect. LCD substrate glass (Non-Alkali, N/A) market has long been supplier market because of limited capa. of major glass companies. Now it seems like that SEC got a new card to deal with them. ( I am not sure this is just bluffing or not.) Several technical issues were already mentioned in article. However, I have two additional concerns. (Although SEC people already solved those issues, these possibly can affect to the cost and throughput.) First, float glass made from Tin bath require surface polishing. Is polishing process applicable for the substrate size larger than G5 (Substrate: 1100 × 1250 mm )? Second, soda-lime glass is softer than N/A glass. This may be a problem for the substrate transfer due to lager glass sagging. The Empire strikes back?
