MULTILAYER ENCAPSULATION WITH INTEGRATED GAS PERMEATION SENSOR

摘要

Barrier stacks according to embodiments of the present invention provide early indication of barrier failure. In some embodiments, the barrier stack includes one or more dyads comprising a first polymer decoupling layer and a second barrier layer. The barrier stack includes one or more integrated gas permeation sensors between the first and second layers of one of the dyads, or between two of the dyads. In some embodiments, the barrier stack can include a primary barrier stack including one or more dyads, one or more integrated gas permeation sensor laterally spaced apart from the primary barrier stack, and a secondary barrier stack including one or more dyads on both the primary stack and the integrated gas permeation sensor(s).
