Abstract
Official abstract text for this publication.
A light-emitting component may include: an electrically active region, including: a first electrode; a second electrode; and an organic functional layer structure between the first electrode and the second electrode; and a thermotropic layer, which is arranged outside the electrically active region.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light-emitting component, comprising: an electrically active region, comprising: a first electrode; a second electrode; and an organic functional layer structure between the first electrode and the second electrode; a thermotropic layer, which is arranged outside the electrically active region; a substrate; and a first cover, wherein the first cover is arranged on the opposite side of the substrate from the electrically active region, wherein the thermotropic layer is arranged between the substrate and the first cover. 2. The light-emitting component as claimed in claim 1 , wherein the thermotropic layer comprises a matrix material in which particles are embedded, which are designed in such a way that they vary their refractive index depending on temperature. 3. The light-emitting component as claimed in claim 2 , wherein the matrix material comprises polymer material. 4. The light-emitting component as claimed in claim 2 , wherein the particles comprise microparticles. 5. The light-emitting component as claimed in claim 1 , further comprising an encapsulation, wherein the encapsulation is arranged on the opposite side of the electrically active region from the substrate; wherein the thermotropic layer is arranged above the encapsulation. 6. The light-emitting component as claimed in claim 1 , further comprising: an encapsulation, wherein the encapsulation is arranged on the opposite side of the electrically active region from the substrate; a second cover arranged above the encapsulation; wherein the thermotropic layer is arranged above the second cover. 7. The light-emitting component as claimed in claim 1 , further comprising: an encapsulation, wherein the encapsulation is arranged on that side of the electrically active region which faces away from the substrate; and a second thermotropic layer, wherein the second thermotropic layer is arranged above the encapsulation. 8. The light-emitting component as claimed in claim 1 , further comprising: an encapsulation, wherein the encapsulation is arranged on that side of the electrically active region which faces away from the substrate; a second cover arranged above the encapsulation; and a second thermotropic layer, wherein the second thermotropic layer is arranged above the second cover. 9. The light-emitting component as claimed in claim 1 , designed as an organic light-emitting diode. 10. A method for producing a light-emitting component, the method comprising: forming an electrically active region, comprising: forming a first electrode; forming a second electrode; and forming an organic functional layer structure between the first electrode and the second electrode; forming a thermotropic layer outside the electrically active region; forming a substrate; and forming a first cover on the opposite side of the substrate from the electrically active region, wherein the thermotropic layer is arranged between the substrate and the first cover.
