Large Area Deposition of a Light Out-Coupling Layer Stack on Low Cost Soda Lime Glass Substrate

摘要

A scalable implementation of a light Out-Coupling Layer Stack (OCLS) on Gen 2 size soda-glass is demonstrated with up to a 2X improvement in green PLED light extraction efficiency. This is a viable and scalable technology and potentially important for next generation high efficacy OLEDs solid state lighting on both rigid as well as temperature sensitive flexible substrate enabling low cost manufacturing and fast commercialization of the technology.
