Abstract

We have discovered a new single-layer environmental barrier for OLEDs. In storage at $65^{\circ}C$ and 85% relative humidity, OLED pixels encapsulated with this barrier have half-lives of approximately one year. We describe the fabrication and properties of the barrier, and results of accelerated storage tests.
