Device for spraying, method therefor and organic electronic construction element

Abstract

The embodiments relate to a device and a method for spraying coatings of organic construction elements. The embodiments relate, in particular, to the spraying of coatings made up of components that do not dissolve in the same solvent, for example, and/or the spraying of a plurality of coatings one after the other. A plurality of spray heads is used, for example one after the other and/or next to one another.
