Encapsulation for an organic electronic component, its production process and its use
View Patent ↗An encapsulation for an organic electronic component, characterized in that the component, encapsulated in a dimensionally stable capsule, is at least partially covered with a protective film.
1. An encapsulation for an organic electronic component arranged on a substrate,
wherein the component is encapsulated in a dimensionally stable capsule attached to the substrate by glue comprising absorbents, and
a protective film covers an entire exterior of the encapsulated component, wherein the entire exterior of the encapsulated component comprises at least an entire outer surface of the dimensionally stable capsule and a top outer entire surface of the substrate,
the protective film being more insulating against moisture and/or oxygen than an adhesive, at least partially loaded with an adsorbent for moisture and/or oxygen, for gluing an organic electronic component to a substrate wherein
said protective film includes at least one thin-barrier film and has a thickness in the range of 1 nm to 500 μm,
wherein said protective film includes a filler and a film made of silicon nitride.
2. An encapsulation for an organic electronic component arranged on a substrate, the encapsulation comprising:
the component encapsulated in a dimensionally stable capsule attached to the substrate by glue; and
a protective film covers an entire exterior of the encapsulated component, wherein the entire exterior of the encapsulated component comprises at least an entire outer surface of the dimensionally stable capsule and a top outer entire surface of the substrate,
the capsule comprising horizontal and lateral areas with respect to the component, wherein the lateral areas protrude from the layer formed by the horizontal areas and the glue is arranged between the lateral areas of the capsule and the substrate wherein said protective film includes a thin-barrier film and has a thickness in the range of 1 nm to 500 μm wherein
the protective film includes a filler.
3. The encapsulation as in claim 2 , wherein said protective film includes a film made of silicon nitride.
4. The encapsulation as in claim 2 , wherein the thin-barrier-film further includes organic layers comprising organic materials chosen from parylenes, hydrofluorocarbons, acrylates or polyester compounds and/or the thin-barrier-film includes inorganic layers comprising inorganic materials chosen from metal oxides, metal nitrides, metal oxynitrides.
5. The encapsulation as in claim 4 , wherein the organic and inorganic layers are deposited in alteration.
6. The encapsulation as in claim 2 , wherein the filler is suitable to impart a specific property profile to the protective film.
