Definitions
- the present invention relates to a method for manufacturing an organic electronic device using an adhesive film.
- the organic electronic device refers to a device capable of inducing charge flow between an electrode and an organic material by using holes and / or electrons. According to the principle of operation, the exciton formed in the organic material layer is separated into electrons and holes by photons introduced into the device from an external light source, and the separated electrons and holes are transferred to different electrodes to be used as current sources.
- the organic light emitting device refers to a self-luminous device using an electroluminescence phenomenon that emits light when a current flows through a light emitting organic compound.
- Organic light emitting devices are attracting attention as next-generation materials in various industrial fields such as displays and lighting because of their advantages of excellent thermal stability and low driving voltage.
- organic light emitting diodes are vulnerable to moisture, so research is needed to compensate for them.
- the present invention relates to a method for manufacturing an organic electronic device using an adhesive film.
- One embodiment of the present invention comprises the steps of attaching an adhesive film to encapsulate the organic electronic device to the front on the substrate on which the organic electronic device is formed;
- the adhesive film relates to a method of manufacturing an organic electronic device including a curable resin and a photoinitiator.
- the adhesive film may be used as an encapsulation layer encapsulating the organic electronic device to the front.
- the encapsulation of the organic electronic device to the front means that the adhesive film is attached to the substrate on which the organic electronic device is formed so that the entire surface of the organic electronic device is entirely covered by the adhesive film.
- the adhesive film is for encapsulating the entire area of the organic electronic device, and the adhesive film does not need to encapsulate the entire substrate. Therefore, the area of the adhesive film can be adjusted according to the type and structure of the desired organic electronic device.
- an organic electronic device refers to a device including an organic electronic device, a substrate on which the organic electronic device is formed, or a structure for protecting the organic electronic device, and the organic electronic element is substantially By a hole and / or an electron means a device capable of inducing the flow of charge between the electrode and the organic material.
- the step of attaching the adhesive film so as to encapsulate the organic electronic device on the front surface of the substrate on which the organic electronic device is formed is performed by using a separately prepared adhesive film.
- the adhesive film may be, for example, to have an adhesive performance by curing the adhesive composition described above.
- attaching the adhesive film may be performed by attaching the adhesive film formed by applying and curing the adhesive composition to an encapsulation substrate with a substrate on the side where the organic electronic device is formed.
- the present invention is not limited to this method.
- the adhesive agent film and the substrate may be attached by applying the adhesive composition directly on the substrate on which the organic electronic device is formed to form the adhesive film.
- the order in which the substrate and the encapsulation substrate are attached to both sides of the adhesive agent is not limited. That is, referring to FIG. 1 as an example, one surface of the adhesive film 40 is preferentially attached to the encapsulation substrate 20, and then the other surface of the adhesive film 40 is formed of an organic electronic device ( 30 may be attached to the formed substrate 10. In addition, as another example, one surface of the adhesive film may be preferentially attached to the substrate on which the organic electronic device is formed, and then the other surface of the adhesive film may be attached to the encapsulation film. In addition, as another example, the substrate and the encapsulation substrate may be simultaneously attached to both surfaces of the adhesive film.
- the step of attaching the adhesive film may be performed by applying a constant pressure.
- attaching the substrate and / or the encapsulation substrate by using the adhesive properties of the adhesive film may be differently described in the term of bonding herein.
