Abstract
The invention relates to a transparent organic light emitting diode (OLED) (), comprising: a substrate material () with a top face () and a bottom face (), whereas at least on the top face () is arranged at least one OLED-layer system with a first electrode layer (), a second electrode layer () and an organic light emitting layer system (), arranged in between said first electrode layer () and said second electrode layer (), whereas said OLED () is performed to emit light via the top face () and via the bottom face () and whereas the top face () and the bottom face () of said OLED () feature at least one bright lucent area () and at least one dark lucent area (). The invention discloses that at least one layer on the top face () features a varying relation between transparency and reflectivity in the lateral extension of the OLED () in such a way, that the OLED () features at least one bright lucent area () and at least one dark lucent area () at the top face () and at the bottom face (), whereas said bright lucent areas () are arranged opposite to said dark lucent areas ().
