Abstract

The present disclosure relates to an organic light emitting display device and a method for manufacturing the same. The present disclosure suggests an organic light emitting display device including an organic layer; a display element layer including a display area representing video data and a pad area extended from the display area, on the organic layer; film elements formed on the display element layer; a film type printed circuit board connected to the pad area; and a reinforcing adhesive filling a space between the film type printed circuit board and the film elements.

First claim

What is claimed is:

1. A manufacturing method of an organic light emitting display device comprising:
depositing a silicon layer comprising amorphous silicon material on a base substrate;
depositing an organic layer on the silicon layer;
forming a display element layer comprising a display area representing video data and a pad area extended from the display area, on the organic layer;
depositing film elements on the display element layer;
connecting a film type printed circuit board mounting a driving IC to the pad area;
filling a reinforcing adhesive in a space between the film type printed circuit board and the film elements;
depositing an adhesive layer on an area corresponding to the organic layer having the film elements;
attaching a cover film on the adhesive layer;
depositing a temporary adhesive layer on the cover film;
attaching a cover glass or cover plastic on the temporary adhesive layer;
irradiating a laser beam to the silicon layer to separate the base substrate and the organic layer which are positioned at both sides of the silicon layer;
connecting the film type printed circuit board to an external printed circuit board;
attaching a protective film on a rear side of the organic layer; and
irradiating an ultra violet light to the temporary adhesive layer to remove the cover glass or cover plastic from the cover film.

2. The method according to claim 1 , wherein the reinforcing adhesive comprises one or more of: an acryl group material and a silicon group material.

3. The method according to claim 1 , wherein the reinforcing adhesive covers an upper space of an upper surface of the film type printed circuit board attached on the pad area and an upper exposed space from the pad area to an end of the display area.

4. The method according to claim 1 , wherein the depositing film elements on the display element layer comprises:
encapsulating the display area with a thin-film type cap;
covering the thin-film type cap and the display area with a barrier film; and
attaching a polarization film on the barrier film covering the display area.

5. The method according to claim 1 , further comprising:
depositing an adhesive layer on an area corresponding to the organic layer having the film elements;
attaching a cover glass or cover plastic on the adhesive layer; and
irradiating a laser beam to the silicon layer to separate the base substrate and the organic layer which are positioned at both sides of the silicon layer.

6. The method according to claim 5 , further comprising:
connecting the film type printed circuit board to an external printed circuit board; and
attaching a protective film on a rear side of the organic layer.

7. The method according to claim 1 , wherein the laser beam is a green laser beam or a UV laser beam.

8. The method according to claim 1 , wherein the laser beam is a green laser beam or a UV laser beam.
