Abstract

An organic optoelectronic component includes a substrate embodied in a light-transmissive fashion, an organic light-emitting element having an organic light-emitting layer between two electrodes, and an organic light-detecting element having an organic light-detecting layer. The organic light-emitting element and the organic light-detecting element are arranged on the substrate. Part of the light generated by the organic light-emitting element during operation enters into the substrate, emerges from the substrate and is detected by the organic light-detecting element.
