Abstract

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.
