Abstract:
1. A transparent organic light emitting diode (OLED) device, comprising: a first electrode layer; second electrode layer; and an organic light emitting layer arranged between said first electrode layer and said second electrode layer; and at least one other layer on top of the second electrode layer, wherein said OLED is configured to emit light via a top surface of said OLED device and via a bottom surface of said OLED device, and wherein at least one of the cathode layer or the at least one other layer is structured to have as varying transparency and reflectivity laterally across the organic light emitting layer such, that the OLED device exhibits at least one first bright lucent area at the top surface and at least one first dark lucent area, at the top surface, that is darker than the at least one first bright lucent area and such that the OLED device exhibits, at the bottom surface, at least one second dark lucent area under the at least one first bright lucent area and exhibits, at the bottom surface, at least one second bright lucent area under the at least one first dark lucent area, wherein the at least one second bright lucent area is brighter than the at least one first dark lucent area and the at least one second dark lucent area.
