Abstract: An optoelectronic device, in particular a display device, comprises: at least one optoelectronic light source, an at least partially transparent front layer, an at least partially transparent support layer, wherein the light source is arranged between the front layer and the support layer, wherein a front side of the light source faces the front layer and a rear side of the light source faces the support layer, and wherein a limiting device is provided in a circumferential direction around the light source, wherein the limiting device limits a spatial region, in which the light source emits light such that total internal reflection of the emitted light, in particular at an interface between the front layer and the outside, is avoided or at least reduced.

Abstract: An optoelectronic apparatus comprises a transparent first cover, at least layer two carriers mounted on the first cover, wherein a plurality of optoelectronic elements configured to emit light are attached to each of the at least two carriers, and a second cover mounted on the at least two carriers, wherein the second cover has at least partially a lower optical transmittance than the first cover and/or the at least two carriers.

Abstract: An optoelectronic device, in particular an at least semi-transparent pane for example for a vehicle, comprises: a cover layer, a carrier layer, an intermediate layer between the cover layer and the carrier layer, wherein at least one and preferably a plurality of optoelectronic light sources, in particular μLEDS, is arranged on at least one surface of the intermediate layer and/or is at least partially embedded in the intermediate layer, wherein the intermediate layer is adapted such that light emitted by the optoelectronic light sources at least partially spreads in and along the intermediate layer and exits the intermediate layer within and/or at a pre-set distance to the respective optoelectronic light source in a direction through the cover layer and/or through the carrier layer.
