Organic electronic component and method for producing organic electronic devices
First Claim
1. A process for the production of an organic electronic component comprising a plurality of organic based functional layers, wherein at least one of the functional organic based layers is applied in a continuous process step in the form of a homogenous, unpatterned coating obtained by a roll-to-roll compatible process selected from the group consisting of one of porous roll coating, dip coating, rod coating, knife coating, blade coating, air knife coating, gravure coating, forward and reverse coating, slot and extrusion coating, slide coating, curtain coating, and spray coating

5. A process for the continuous production of an organic component, comprising the following production steps:
-
applying to a substrate which is a continuous, coherent web or sheet feed comprising a succession of individual sheets, by a continuous coating method, a functional organic material layer, which is one of conducting, semiconducting or insulating material, as a homogenous, unpatterned coating;
printing a varnish in patterned form over the functional layer; and
patterning the functional layer by means of the varnish directly or via further process steps. - View Dependent Claims (6, 7, 8)
