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.

Method for the production of an organic light emitting illuminant

A coating device for producing an organic light-emitting illuminant comprising mutually adjacent regions having in each case different emission colors, includes a vacuum chamber, a device for linearly transporting a substrate, and a plurality of coating sources and diaphragms, provides OLED structures which have an improved intensity of the light emission. The thicknesses of the hole transport, emission and electron transport layers in the mutually adjacent regions differ and are in each case set such that an optimum coupling-out for the light color emitted in the corresponding region is achievable.
