Abstract
In a method for producing an organic light emitting illuminant, a base electrode layer is formed over a substrate, an organic light emitting layer is formed over at least one portion of the base electrode layer, and a top electrode layer is formed over at least one portion of the organic light emitting layer, the layers being formed in the shape of strips. The strip-shaped formation of the layers is carried out in a coating process in an in-line vacuum coating system having stationary shadowing masks on the advancing substrate such that at least one area of the base electrode layer remains uncoated once the layers have been formed.
Claims16
A method form producing an organic light emitting illuminant, comprising the steps of
- providing a substrate
- forming a bottom electrode layer above the substrate,
- forming at least one organic light emitting layer in strip-type fashion above at least one part of the bottom electrode layer,
- forming a top electrode layer in strip-type fashion above at least one part of the organic light emitting layer;
- and
- forming a conductor track layer in strip-type fashion,
- wherein the at least one organic light emitting layer, the top electrode layer and the conductor track layer are formed in strip-type fashion by coating in an inline vaccuum coating installation with stationary shadow masks on the substrate guided past the masks, such that at least one region of the bottom electrode layer remains uncoated after the at least one organic light emitting layer, the top electrode layer and the conductor track layer have been formed.
