Abstract

An electronic device includes a panel which forms at least a part of a display unit and which is folded along a folding line; a bending unit arranged to be adjacent to the long side of the panel; a film unit which is connected to the bending unit and which includes a display driving circuit; an FPCB which is connected to the film unit and which connects a processor and the display driving circuit; and a protection member arranged on the bending unit so as to cover at least a part of the bending unit, wherein the protection member is adhered onto one surface of the bending unit, at which the bending unit makes contact with a bracket.

Claims (21)

1. An electronic device comprising:

a bracket assembly including a first bracket, a second bracket and a hinge for allowing the first bracket and the second bracket to rotate with respect to each other;

a flexible display including a window, the flexible display disposed on the first bracket and the second bracket and being configured to be folded when the first bracket and the second bracket rotate with respect to each other, the flexible display comprising a first portion visually exposed through the window, a second portion parallel to the first portion and disposed between at least part of the first portion and the first bracket and a bending portion spaced from a side of the first bracket and including the second portion;

a film, comprising an adhesive, including a first surface contacting the first bracket and a second surface contacting the second portion and configured to reduce movement of the flexible display due to deformation of the window when the flexible display is folded; and

a deco coupled to the side of the first bracket and including a portion parallel to and spaced from the window.

2. The electronic device of claim 1 , wherein the deco is spaced from the window.

3. The electronic device of claim 1 , wherein the window includes a flexible material comprising polyimide.

4. The electronic device of claim 1 , wherein the window includes a flexible material comprising polyethylene (PET).

5. The electronic device of claim 1 , wherein the film comprises a pressure-sensitive adhesive.

6. The electronic device of claim 1 , further comprising:

a display driver integrated circuit electrically connected to pixels of the flexible display; and

an anti-static film disposed between at least the display driver integrated circuit and the first bracket.

7. The electronic device of claim 6 , wherein the anti-static film includes a portion disposed between at least the film and the second portion.

8. The electronic device of claim 6 , wherein the anti-static film includes a portion disposed between at least the film and the first bracket.

9. The electronic device of claim 6 , wherein the film is disposed closer to the side of the first bracket than the display driver integrated circuit.

10. The electronic device of claim 1 , comprising a foldable smartphone.

11. The electronic device of claim 1 , wherein the second portion is attached to the first bracket at a location closer to the side of the first bracket than a display driver integrated circuit.

12. The electronic device of claim 1 , wherein the window includes a flexible material comprising a ductile material.

13. The electronic device of claim 1 , wherein the window includes a flexible material comprising a deformable material.

14. The electronic device of claim 1 , wherein the window includes a flexible material comprising a printable material.

15. The electronic device of claim 1 , wherein the window includes a flexible material comprising a replaceable structure.
