LICHT EMITTIERENDES BAUTEIL

摘要

The unit has several organic units formed to emit light of different colors, where each organic unit has a stack of organic layers that is arranged between an electrode and a back electrode (160). The stack of organic layers has a light emitting layer region (140) that is formed between holes and electrons transporting layer regions. The thickness of the holes and electrons transporting layer regions is equal for all the organic units. The light emitting layer region has an emission zone (141), where a layer thickness of the light emitting layer region is adjusted in a predefined manner.
