Abstract:
An encapsulation structure for an optoelectronic component may include: a barrier thin-film layer for protecting an optoelectronic component against chemical impurities; a cover layer applied above the barrier thin-film layer and serving for protecting the barrier thin-film layer against mechanical damage; and an intermediate layer applied on the barrier thin-film layer between barrier thin-film layer and cover layer and including a curable material designed such that when the non-cured intermediate layer is applied to the barrier thin-film layer, particle impurities at the surface of the barrier thin-film layer are enclosed by the intermediate layer and the applied intermediate layer has a substantially planar surface, and that after the intermediate layer has been cured, mechanical loads on the barrier thin-film layer as a result of particle impurities during the application of the cover layer are reduced by the intermediate layer.
