Claims20
An encapsulated optoelectronic device, comprising:
- an interior region comprising a status indicator disposed therein, the status indicator comprising a reactive layer that undergoes a visible change in at least one property upon exposure to oxygen and/or moisture.
A process for detecting oxygen and/or moisture within an encapsulated optoelectronic device, the process comprising
- disposing a status indicator within an interior region of the encapsulated optoelectronic device, wherein the status indicator comprises a reactive layer sensitive to the oxygen and/or moisture within the interior region;
- and
- optically changing at least one property of the reactive layer upon exposure to the oxygen and/or moisture.
