A radiation emitting device includes a substrate and a layer sequence disposed on top of the substrate. The layer sequence includes a first electrode surface with a first contact for applying a voltage, at least one functional layer that emits radiation during operation, and a second electrode surface. In the layer sequence, a plurality of partial regions is present that is modified in such a way that the emission of radiation visible to an external observer therefrom is interrupted. The distribution density of these partial regions can vary depending on their distance from the contact.

Light emitting device with a layer sequence having electrode surfaces and partial regions

The invention relates to a radiation emitting device, with a substrate () and a layer sequence disposed on top of it. Said layer sequence comprises a first electrode surface () with a first contact () for applying a voltage, at least one functional layer (), which emits radiation during operation, and a second electrode surface (). In the layer sequence, a plurality of partial regions is present that is modified in such a way that the emission of radiation visible to an external observer therefrom is interrupted. The distribution density of these partial regions varies depending on their distance from the contact.

Radiation emitting device

Disclosed is a method for manufacturing an organic optoelectronic device. The method comprises providing a substrate, disposing a first electrode on the substrate, disposing a metal pad on the substrate, electrically separated from the first electrode, disposing a first material over the first electrode and at least partially over the metal pad, applying a beam, wherein the beam ablates the first material in an ablation window so that the ablation window includes at least a portion of an edge of the metal pad, and disposing a second electrode over the first material and over the ablation window so that the second electrode is in electrical contact with the at least a portion of an edge of the metal pad.

Laser process for reliable and low-resistance electrical contacts

Disclosed is an organic electroluminescent display, comprising a first active electrode region and a first dummy electrode region, the first dummy electrode region electrically isolated from the first active electrode region. Further disclosed is an organic electroluminescent display, comprising a first active electrode region, a first dummy electrode region, and a blocking layer extending on said dummy electrode region preventing light emission.
