Organic light-emitting diode, organic light module, and method for producing an organic light-emitting diode

An organic light module comprising:

• a plurality of organic light-emitting diodes comprising
• a substrate having a top side and one or a plurality of substrate side surfaces running transversely with respect to the top side, wherein the top side and the substrate side surfaces are connected to one another in each case via a substrate edge, and
• an organic layer sequence applied to the top side and having an emitter layer, which generates electromagnetic radiation during intended operation of the light-emitting diode, wherein the radiation is coupled out from the organic light-emitting diode via a luminous surface,
• wherein in a plan view of the luminous surface the organic layer sequence adjoins at least a partial region of at least one substrate edge, wherein in the partial region the luminous surface extends at least as far as the corresponding substrate edge, an encapsulation formed in an uninterrupted and continuous fashion is applied to the organic layer sequence, the encapsulation, at least in the region of the substrate edge adjoining the organic layer sequence, is led right onto the associated substrate side surface, at least partly covers the latter and is in direct contact with the substrate side surface, wherein
• at least two organic light-emitting diodes are combined such that the substrate edges adjoining the organic layer sequences bear against one another and, as a result, a common luminous surface that appears continuous and free of interruption is formed during the operation of both light-emitting diodes.

A method for producing an organic light-emitting diode comprising the following steps:

• A) providing a substrate having a top side and one or a plurality of substrate side surfaces running transversely with respect to the top side, wherein the top side and the substrate side surfaces are connected to one another in each case via a substrate edge;
• B) applying an organic layer sequence to the top side of the substrate, such that in a plan view of the top side the organic layer sequence adjoins at least one substrate edge at least in a partial region, wherein the organic layer sequence comprises at least one emitter layer that emits electromagnetic radiation during intended operation of the light-emitting diode;
• C) applying an encapsulation formed in an uninterrupted and continuous fashion to the organic layer sequence, wherein the encapsulation, at least in the region of the substrate edge adjoining the organic layer sequence, is led onto the associated substrate side surface, such that the latter is at least partly covered by the encapsulation, wherein
• in step A) the substrate is provided on an auxiliary carrier, wherein the top side of the substrate lies on an elevated plane relative to the auxiliary carrier and a step is formed between the top side and the auxiliary carrier, wherein a substrate edge belonging to the step forms a tear-off edge,
• in step B) the organic layer sequence is applied laterally beyond the tear-off edge in places, such that both the top side and the auxiliary carrier are at least partly covered by the organic layer sequence, wherein during application the step has the effect that the organic layer sequence is interrupted along the tear-off edge and, as a result, the parts of the organic layer sequence which are applied on the auxiliary carrier are not joined with the parts of the organic layer sequence which are situated on the top side of the substrate,
• in a step D), the auxiliary carrier is detached, wherein the parts of the organic layer sequence which are situated on the auxiliary carrier, together with the auxiliary carrier, are removed from the substrate.
