Abstract
A method for manufacturing a polymer OLED, wherein after the application of a number of active layers onto a substrate to form the OLED, these active layers are encapsulated with at least one sealing, wherein prior to the application of the sealing, the OLED is heated for some time, as a result of which volatile substances present in the active layers evaporate from the OLED, and subsequently the respective sealing is applied. Optionally independently of the heating of the OLED prior to the application of the sealing, the sealing can be formed by at least a UV-setting resist layer which is applied with one of the following techniques; printing, such as inkjet printing, screen printing, tampon printing, offset printing and the like, or a mechanical coating technique, such as spray coating, curtain coating, spin coating and the like.
