Patent ID: 7781961

Claim:
Top emitting, electroluminescent component comprising a substrate, a first electrode closest to the substrate, a second, transparent electrode located at a distance from the substrate, and at least one organic layer arranged between the two electrodes, wherein at least one of the organic layers is a light-emitting layer, and wherein a coupling-out layer designed for improving the coupling-out of light is arranged on that side of the second electrode which is remote from the at least one organic layer, said coupling-out layer comprising frequency conversion centers which partly absorb the light emitted in the at least one organic layer and emit it again with an altered frequency, wherein the coupling-out layer is an organic matrix in which the frequency conversion centers are provided, wherein the frequency conversion centers are provided by at least one dye, wherein the dye concentration in the coupling-out layer is less than 1% by volume, wherein the transmittance degree of the coupling-out layer at the wavelength of the light emitted by the at least one organic layer is greater than 0.4 and the transmittance of the coupling-out layer at the wavelength of the light emitted by the frequency conversion centers is greater than 0.6.
