Research Progress of Thin Film Encapsulation of Organic Light-Emitting Devices
Organic light-emitting devices (OLEDs) are extremely sensitive to vapor and oxygen. The influence of inleakage of vapor and oxygen which can corrode organic functional layer and the electrode material on device's lifetime was serious. Based on the requirements of encapsulation materials
this paper analyzes the most promising OLEDs encapsulation technology —thin film encapsulation
which mainly focuses on the classification and research status.
