Organic light-emitting device having homogenous brightness distribution

摘要

An organic light-emitting device comprising an active layer for producing radiation having a first side surface and a second side surface adjoining a corner edge. A first contact strip extends along the first side surface for injecting charge carriers of a first type into the active layer. A second contact strip extends along the second side surface for injecting charge carriers of a second type into the active layer. The first side surface has a recessed region adjoining the corner edge, and the injection of charge carriers from the first contact strip is suppressed in the recessed region.

1. An organic light-emitting device comprising:
an active layer configured to produce radiation having a first side surface and a second side surface adjoining a corner edge; a first contact strip extending along the first side surface configured to inject charge carriers of a first type into the active layer; and a second contact strip extending along the second side surface configured to inject charge carriers of a second type into the active layer, wherein: the first side surface has a recessed region adjoining the corner edge and configured so the injection of charge carriers from the first contact strip is suppressed in the recessed region, the active layer comprises a first main surface and a second main surface, and a first contact connection comprising the first contact strip extends over the first main surface and a second contact connection comprising the second contact strip extends over the second main surface, and the first contact connection has a conductivity profile, the conductivity decreasing from a center of the first side surface toward the recessed region.
