Abstract

According to various embodiments of the present disclosure, there is provided a fabrication method for fabricating an exterior member of an electronic device. The fabrication method may include a film disposing step of disposing a film on an exterior member in which one face is formed as a first curved face, and a lamination step of laminating the film on the exterior member. The fabrication method as described above may be variously implemented according to embodiments.

First claim

What is claimed is:

1 . A method for fabricating an exterior member of an electronic device, the method comprising:
disposing a film on the exterior member comprising a face that is formed as a first curved face; and laminating the film on the exterior member of the electronic device.

2 . The method of claim 1 , wherein the film is formed in a three-dimensional shape that corresponds to the first curved face of the exterior member.

3 . The method of claim 1 , wherein the film is formed, through a thermal molding, in a three-dimensional shape that corresponds to the first curved face of the exterior member.

4 . The method of claim 1 , wherein the film is formed, through a chemical treatment, in a three-dimensional shape that corresponds to the first curved face of the exterior member.

5 . The method of claim 1 , wherein an induction layer is laminated on the face of the film and wherein the induction layer is contracted or expanded according to a change in temperature to deform the film into the three-dimensional shape.

6 . The method of claim 1 , wherein at least one pattern is formed on the film.

7 . The method of claim 1 , wherein laminating includes a roller pressing that press the film on the exterior member using a roller that rolls on the film.

8 . The method of claim 1 , further comprising:
seating a jig on the exterior member prior to laminating the film wherein the jig holds the film.

9 . The method of claim 1 , wherein laminating the film further includes:
disposing an inflatable elastic member on the film using a fluid; and pressing the film on the exterior member by the inflatable elastic member.

10 . The method of claim 1 , wherein laminating the film further includes:
disposing an elastic member that has elasticity on a film; and pressing the film on the exterior member by the elastic member.

11 . The method of claim 1 , wherein laminating the film further includes injecting a fluid toward the film.

12 . The method of claim 1 , further comprising:
processing the film using irradiating a laser beam to the film.

13 . The method of claim 1 , further comprising:
disposing an adhesive between the exterior member and the film prior to laminating the film.

14 . An apparatus for fabricating an exterior member of an electronic device, the apparatus comprising:
an aligner configured to align a film on the exterior member comprising a face that is formed as a first curved face; and a laminator configured to press the film on the exterior member of the electronic device.

15 . The apparatus of claim 14 , wherein the aligner is further configured to include a jig holding the film that is seated on the exterior member, and wherein the laminator is further configured to include a roller that rolls on the film to press the film on the exterior member.

16 . The apparatus of claim 15 , wherein the jig is fabricated to include a second curved face comprising a curvature larger than or equal to the curvature of the first curved face.

17 . The apparatus of claim 15 , wherein the jig includes:
a facing portion that faces the film; and a plurality of suction portions that cause the facing portion and the film to be in close contact with each other by discharging air.

18 . The apparatus of claim 14 , wherein the laminator is further configured to include an elastic member that is disposed on the film seating on the exterior member:
a fluid supply that supplies a fluid to the elastic member; and the elastic member presses the film on the exterior member using the fluid supply to be expanded.

19 . The apparatus of claim 14 , wherein the laminator is further configured to include an elastic member comprising elasticity, and wherein the elastic member presses the film on the exterior member, the film being laminated on the exterior member.

20 . The apparatus of claim 14 , wherein the laminator is further configured to include:
a fluid injector configured to inject a fluid toward the film that is seated on the exterior member; and a fluid supply configured to supply a fluid to the fluid injector, and wherein the fluid presses the film on the exterior member.

21 . An electronic device comprising:
an exterior member that is disposed outside the electronic device and comprises a face that is at least partially formed as a first curved face; and a film that is three-dimensionally formed to include a second curved face corresponding to the first curved face, the second curved face being at least partially laminated on the face of the exterior member.

22 . The electronic device of claim 21 , wherein the exterior member comprises at least one of glass, a transparent ceramic, sapphire, or a plastic.
