Disclosed is a method for the production of an organic light emitting device of the OLED type, the method including the following sequences of steps: a step of forming a stack of layers on a substrate; the stack including, successively and in the following order, a first electrode, an organic layer and a second electrode; a step of positioning a cover; a step of forming a connection pad. The method also includes: a step of fixing a first end of at least one elongated electrical connection member to an area of the connection pad covering a portion of the second face of the cover and a step of forming a layer of resist, the layer of resist being so configured as to preserve an electrical access to a second end of the elongated electrical connection member above the layer of resist.

Electrical connection of an OLED device

The invention relates to an organic light-emitting diode (OLED) comprising a stack comprising, in sequence and in the following order, a substrate (), a first electrode (), an organic layer (), and a second electrode (), characterized in that it comprises a layer of adhesive () and a cover () fixed onto said stack using said layer of adhesive (), and the cover () comprises at least one through-opening (), wherein electrical access to an electrode () is possible through said opening (). The present invention can be more specifically used in electronic devices having screens and lighting.
