Abstract
An OLED device, comprising: a substrate; a first electrode formed over the substrate; one or more organic layers formed over the first electrode, at least one organic layer being a light-emitting layer; and a bi-layer electrode comprising a first transparent conductive protective hermetic layer formed over the one or more organic layers, and a second transparent conductive non-hermetic layer formed over the first transparent conductive protective hermetic layer.

An OLED device, comprising:
- a substrate;
- a first electrode formed over the substrate;
- one or more organic layers formed over the first electrode, at least one organic layer being a light-emitting layer;
- and
- a bi-layer electrode comprising a first transparent conductive protective hermetic layer formed over the one or more organic layers, and a second transparent conductive non-hermetic layer formed over the first transparent conductive protective hermetic layer.
2 more elements
A method of forming a top-emitting OLED device, comprising:
- providing a substrate with a first electrode and one or more organic layers formed thereon, at least one organic layer being a light-emitting layer;
- and
- forming a bi-layer transparent top electrode by forming a first transparent conductive protective hermetic layer over the one or more organic layers at a temperature less than 140 degrees C., and forming a second transparent conductive non-hermetic layer over the first transparent conductive protective hermetic layer.
