Thin Film Encapsulation,antee a lifetime, which exceeds 10 years of operation. By coating the device from both sides, one can create displays, which are fully flexible. Failure modes and the problems creating such coatings are discussed in detail. The concept of multilayer barriers is introduced. The multilayers deal with

However, the device degradation mechanisms in OLEDs have not yet been completely performed, because there are few characterization methods for evaluating OLEDs under device driving from a microscopic viewpoint. A characterization method for
