Organic electroluminescent device and encapsulation method

DETAILED DESCRIPTION Generally, the present invention relates to organic electroluminescent devices and methods of preparing such devices.
One aspect of the invention provides an organic electroluminescent device that includes a first electrode, a second electrode, a light emitting structure disposed between the first and second electrode, a conductive layer disposed over at least a portion of the second electrode, and a non-conductive material defining an opening through which the conductive layer is in electrical communication with the second electrode.
Another aspect of the invention provides a method of preparing an organic electroluminescent device.
An electroluminescent structure is formed that includes a first electrode, a second electrode, and a light emitting structure disposed between the first and second electrodes.
An opening is formed in a non-conductive material and aligned with a surface of the second electrode.
Electrical communication is established between a conductive layer and the second electrode through the opening in the non-conductive material.
The method can be a roll-to-roll process.
The above summary of the present invention is not intended to describe each disclosed embodiment or every implementation of the present invention.
The Figures and the detailed description that follow more particularly exemplify these embodiments.
