Abstract

Abstract : We have developed pressure sensitive adhesive (PSA) as adhesive encapsulation film for OLED device. The developed PSAs are found to bring high reliability on OLED encapsulated with "face seal" method without inorganic passivation under 85°C and 85%RH over 500hr. The developed PSAs are also designed to satisfy both barrier ability and high transparency, allowing simple lamination without any heating.
