Abstract
In at least one embodiment of the organic light-emitting diode (1), the latter comprises a radiation-permeable carrier (2). On the carrier (2) there is mounted at least one organic active layer (3) provided for the generation of radiation. Also mounted on the carrier (4) is a plurality of liquid lenses (4). In the switched-off state of the active layer (3), the organic light-emitting diode (1) has in respect of visible light a transmittance of at least 0.55 and is pellucid. In the switched-on state of the active layer (3), the liquid lenses (4) are configured for increasing the light outcoupling efficiency of radiation out of the light-emitting diode (1) and the light-emitting diode (1) appears turbid.
