Abstract
An organic electroluminescent device includes a transparent substrate having a conductive coating, a plurality of electroactive layers, a cathode layer, and a protective wax layer. The wax layer may be disposed directly on an electrode, particularly a cathode. The wax layer alone protects the cathode and no getter material is required to exclude oxygen and/or moisture. An OLED lighting device capable of emitting light from front and back surfaces, wherein an adhesive layer, particularly a wax layer, is disposed between cathodes of two organic electroluminescent devices positioned back to back.
Claims20
An organic electroluminescent device having a wax layer disposed directly on an electrode, the wax layer comprising a wax composition free of getter material.
An OLED lighting device capable of emitting light from front and back surfaces, the lighting device comprising an adhesive layer disposed between cathodes of two organic electroluminescent devices positioned back to back.
A process for packaging an organic electroluminescent device, said process comprising coating a wax layer directly on a cathode of the organic electroluminescent device and allowing exposure of the wax-coated device to at least a small amount of air or moisture.
A process for fabricating an organic electroluminescent device capable of emitting light from front and back surfaces, said process comprising bonding a first and second organic electroluminescent device in a back-to-back configuration.
An organic electroluminescent device comprising a transparent substrate having a conductive coating, a plurality of electroactive layers, a cathode layer, and a protective wax layer.
