Protective film module and method for manufacturing the same
A protective film module includes a first film protecting a first face of a thin-film glass, a first adhesive layer disposed between the thin-film glass and the first film and contacting the first face of the thin-film glass, a second film disposed on the first adhesive layer, and covering the thin-film glass, and having a closed line shape in a plan view of the protective film module, a third film protecting a second face opposite to the first face of the thin-film glass, and a second adhesive layer disposed between the thin-film glass and the third film and in contact with the second film, wherein the thin-film glass is disposed in an inner space defined between the second film, the first adhesive layer, and the second adhesive layer.
1 . A protective film module comprising:
a first film protecting a first face of a thin-film glass;
a first adhesive layer disposed between the thin-film glass and the first film and contacting the first face of the thin-film glass;
a second film disposed on the first adhesive layer, and covering the thin-film glass, and having a closed line shape in a plan view;
a third film protecting a second face opposite to the first face of the thin-film glass; and
a second adhesive layer disposed between the thin-film glass and the third film and in contact with the second film,
wherein the thin-film glass is disposed in an inner space defined between the second film, the first adhesive layer, and the second adhesive layer.
2 . The protective film module of claim 1 , wherein a thickness of the second film is in a range of about 1.3 to about 1.7 times of a thickness of the thin-film glass.
3 . The protective film module of claim 1 , wherein a side face of the thin-film glass is spaced, by a distance, from an inner side face of the second film adjacent to the side face of the thin-film glass.
4 . The protective film module of claim 1 , wherein the first adhesive layer is in contact with the first film.
5 . The protective film module of claim 1 , wherein corresponding side faces of the first film, the first adhesive layer, and the second film are aligned with each other.
6 . The protective film module of claim 1 , wherein an outer side face of the second film protrudes outwardly beyond an outer side face of the second adhesive layer.
7 . The protective film module of claim 1 , wherein the second face of the thin-film glass is spaced apart from the second adhesive layer by a distance.
8 . The protective film module of claim 1 , wherein corresponding side faces of the second adhesive layer and the third film are aligned with each other.
9 . The protective film module of claim 1 , wherein a face of the second adhesive layer facing the second face of the thin-film glass is adhered only to a face of the second film adjacent to the second adhesive layer.
10 . The protective film module of claim 1 , wherein the second film is detachably bonded to the second adhesive layer.
11 . The protective film module of claim 1 , further comprising:
at least one pad disposed between the second adhesive layer and the thin-film glass and having a thickness smaller than a minimum distance between the second face of the thin-film glass and the second adhesive layer.
12 . A method for manufacturing a protective film module, the method comprising:
bonding a first adhesive layer onto a first film;
bonding a second film to an outer portion of the first adhesive layer;
detachably bonding a thin-film glass onto the first adhesive layer;
bonding a second adhesive layer onto the second film;
bonding a third film onto the second adhesive layer; and
pressing the third film with a roller, wherein
the first film protects a first face of the thin-film glass,
the first adhesive layer is disposed between the thin-film glass and the first film and contacts the first face of the thin-film glass,
the second film is disposed on the first adhesive layer, surrounds the thin-film glass, and has a closed line shape in a plan view,
the third film protects a second face opposite to the first face of the thin-film glass,
the second adhesive layer is disposed between the thin-film glass and the third film, and
the thin-film glass is disposed in an inner space defined between the second film, the first adhesive layer, and the second adhesive layer.
13 . The method of claim 12 , wherein in case that the third film is pressed with the roller, a pressure of the roller is transmitted to the first adhesive layer, the second adhesive layer, the first film, and the second film through a pressing area of the third film overlapping the second film in a plan view.
14 . The method of claim 12 , wherein
in case that the third film is pressed with the roller, the second film is compressed, and
a thickness of the compressed second film is greater than a thickness of the thin-film glass.
15 . The method of claim 12 , wherein in the pressing of the third film with the roller, the second face of the thin-film glass is spaced apart from the second adhesive layer.
16 . The method of claim 12 , wherein a thickness of the second film is in a range of about 1.3 to about 1.7 times of a thickness of the thin-film glass.
