Method and apparatus for attaching display device to exterior member in an electronic device

1. A method for attaching a display device to an exterior member in an electronic device, the method comprising:

arranging a tube to be at least partially surrounded by a foldable flexible display device; arranging the flexible display device to be at least partially surrounded by the exterior member, the flexible display device and the exterior member being folded;

inflating the tube by injecting a gas into the tube,

applying an adhesive between the exterior member and the flexible display device, before inflating the tube, and

removing the tube from a space which is formed by inner surfaces of the flexible display device, after the tube inflated,

wherein the flexible display device is attached to inner surfaces of the exterior member by the inflation of the tube.

2. The method of claim 1 , wherein the arrangement of the tube to be at least partially surrounded by a foldable flexible display device comprises:

arranging the tube on the flexible display device, in a state where the flexible display device is unfolded; and

folding the flexible display device to at least partially surround the tube.

3. The method of claim 1 , wherein the arrangement of the tube to be at least partially surrounded by a foldable flexible display device comprises:

folding the flexible display device, in a state where the flexible display device is unfolded; and

arranging the tube to be at least partially surrounded by the folded flexible display device.

4. The method of claim 1 , further comprising arranging a tube housing to surround at least a part of the tube, before inflating the tube.

5. The method of claim 4 , wherein the inflation of the tube comprises:

injecting the gas in a first direction through a gas injector inserted in the tube;

inflating another part of the tube, the another part of the tube being exposed from the tube housing; and

moving the tube housing in a direction opposite to the first direction.

6. The method of claim 5 , wherein as the tube housing is moved in the direction opposite to the first direction during the gas injection, the tube is exposed further from the tube housing and inflated, causing the flexible display device be pressed into close contact with the exterior member.

7. The method of claim 6 , further comprising removing the tube housing from the tube, after closely contacting the flexible display device with the exterior member.

8. The method of claim 7 , further comprising, with the tube inflated, keeping the flexible display device in close contact with the exterior member for a predetermined time after the tube housing is removed from the tube.

9. The method of claim 8 , further comprising contracting the tube by discharging the gas introduced in the tube through the gas injector, after the flexible display device has been in close contact with the exterior member for the predetermined time.
