Abstract

The present application relates to a laminate for encapsulation, an organic light emitting apparatus, and methods for manufacturing the same, and process costs may be reduced and productivity may be significantly enhanced by manufacturing the organic light emitting apparatus using the laminate for encapsulation through a roll process.

First claim

The invention claimed is:

1. A method for manufacturing an organic light emitting apparatus, the method comprising:
forming a laminate for encapsulation by laminating an encapsulation film, an adhesive film, and a protective film;
forming two or more pattern units including an encapsulation layer and an adhesive layer provided on any one surface of the encapsulation layer by cutting the encapsulation film and the adhesive film in a film thickness direction without cutting the protective film;
removing a side film between the pattern units so that the pattern units are separated from each other;
removing the protective film while fixing the pattern units side of the laminate for encapsulation on a stage of an apparatus or on a tray for cohesion with an organic light emitting unit; and
cohering an organic light emitting device including a substrate and two or more organic light emitting units provided on the substrate to the adhesive layer side of the pattern units so that each of the pattern units and each of the organic light emitting units correspond to each other.

2. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the forming a laminate for encapsulation comprises:
laminating the encapsulation film and the adhesive film; and
laminating the adhesive film with the protective film.

3. The method for manufacturing an organic light emitting apparatus of claim 2 , wherein the laminating the encapsulation film and the adhesive film is forming the adhesive film through coating an adhesive composition on the encapsulation film and then curing the result.

4. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the forming a laminate for encapsulation comprises:
laminating the protective film and the adhesive film; and
laminating the adhesive film with the encapsulation film.

5. The method for manufacturing an organic light emitting apparatus of claim 4 , wherein the laminating the protective film and the adhesive film is forming the adhesive film through coating an adhesive composition on the protective film and then curing the result.

6. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the encapsulation film is an inorganic material film, an inorganic material pattern film including a support layer and two or more inorganic material patterns provided on the support layer, an organic material film, or a film having a laminated structure in which an organic material layer and an inorganic material layer are laminated alternately.

7. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the encapsulation film is a metal foil, or a metal clad film including an insulation layer and two or more metal patterns provided on at least one surface of the insulation layer.

8. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the laminate for encapsulation includes a polymer layer provided on a surface opposite to the surface adjoining the adhesive film of the encapsulation film, and the polymer layer is cut in a film thickness direction together with the encapsulation film and the adhesive film.

9. The method for manufacturing an organic light emitting apparatus of claim 1 , wherein the cohesion of the laminate for encapsulation having the pattern units and the organic light emitting device is carried out so that each of the pattern units of the laminate for encapsulation covers each of the organic light emitting units.

10. The method for manufacturing an organic light emitting apparatus of claim 1 , further comprising:
removing the protective film from the laminate for encapsulation having the pattern units; and
cohering the organic light emitting device including the substrate and the two or more organic light emitting units provided on the substrate to the adhesive layer side of the laminate for encapsulation having the pattern units so that each of the pattern units and each of the organic light emitting units correspond to each other.

11. The method for manufacturing an organic light emitting apparatus of claim 10 , further comprising removing the carrier film from the laminate for encapsulation having the pattern units.

12. A method for manufacturing an organic light emitting apparatus, the method comprising:
forming a laminate for encapsulation by laminating an encapsulation film, an adhesive film, and a protective film;
forming two or more pattern units including an encapsulation layer and an adhesive layer provided on any one surface of the encapsulation layer by cutting the encapsulation film and the adhesive film in a film thickness direction without cutting the protective film;
removing a side film between the pattern units so that the pattern units are separated from each other;
attaching a carrier film on the side provided with the encapsulation layers of the pattern units so as to cover all the encapsulation layers of the two or more pattern units; and
after attaching the carrier film, cutting the laminate so that the number of the pattern units is the same as the number of organic light emitting devices included in an apparatus including the organic light emitting devices.
