Abstract:
An organic electroluminescent device for emitting light, comprising a substrate (1), a first electrode (2) and a second electrode (4) and having at least one light-emitting layer (3) arranged between the electrodes (2, 4), wherein the first electrode (2), which is intended to transmit the light (5) generated in the organic light-emitting layer (3), comprises a current distributing layer (21, 22), to stimulate uniform light emission, having a structure of conductor tracks of titanium nitride (21) intended to conduct an operating current, and a plurality of regions of titanium oxide (22) adjoining the structure of conductor tracks and intended to transmit the light (5) generated.
Abstract:
An electroluminescent light source includes a substrate and a layer structure applied to the substrate for emitting light at least on the side facing away from the substrate. The layer structure includes an electroluminescent layer between two electrodes. A partially transparent encapsulation device forms a closed volume around the layer structure, and is filled with a dielectric fluid which is substantially chemically inert with respect to the layer structure. The fluid contains particles for absorbing parts of the light emitted by the layer structure and for re-emitting light of a different wavelength. The density of the particles is selected such that the particles in the dielectric fluid are in the suspended state in the operational state of the light source.

Abstract:
The invention relates to an electroluminescent device with a transparent cathode. Said electroluminescent device comprises a substrate (1) and, adjacent to said substrate (1), a laminated body composed of a first electrode (2), an electroluminescent layer (3) and a second metallic electrode (4). Said second electrode (4) is covered with transparent dielectric layers (5), which increase the transmission of light through the second metallic electrode (4) and serve as filters.
