Abstract

Disclosed is a mobile terminal, comprising: a display; a metal frame coupled to a rear surface of the display by an adhesive tape, and having a screw-coupling groove on a rear surface thereof; a front case coupled to the rear surface of the metal frame, and having a screw-coupling hole; a screw inserted into the screw-coupling groove and the screw-coupling hole on a rear surface of the front case; and a rear case coupled to the front case, and configured to cover the rear surface of the metal frame. Under such configuration, the rear surface of the display is coupled to the case. Accordingly, the size of a bezel portion disposed on a side surface of the mobile terminal can be prevented from increasing, and a display panel can be easily separated from the front case.

Claims

1. A mobile terminal, comprising:

a display;

a metal frame coupled to a rear surface of the display by an adhesive tape, and having a screw-coupling groove on a rear surface thereof;

a front case coupled to the rear surface of the metal frame, and having a screw-coupling hole;

a screw inserted into the screw-coupling groove and the screw-coupling hole on a rear surface of the front case; and

a rear case coupled to the front case, and configured to cover the rear surface of the metal frame.

2. The mobile terminal of claim 1, wherein the metal frame further comprises a boss portion protruding from a circumferential surface of the screw-coupling groove toward the rear surface of the metal frame, and the boss portion inserted into the screw-coupling hole of the front case.

3. The mobile terminal of claim 1, wherein the metal frame is provided with an opening at a central part thereof.

4. The mobile terminal of claim 3, wherein a graphite sheet is inserted into the opening.

5. The mobile terminal of claim 3, wherein the front case is provided with a protruding portion having a front surface protruding in correspondence to a shape of the opening, and a concaved rear surface, and

wherein the protruding portion is inserted into the opening.

6. The mobile terminal of claim 1, wherein the adhesive tape is not attached to an edge region of the display.

7. The mobile terminal of claim 1, wherein the metal frame is formed as at least one corner region thereof is cut-out.

8. The mobile terminal of claim 1, wherein a concaved portion partially protrudes from an edge region of the front case toward a front surface of the front case, and

wherein part of the metal frame corresponding to the concaved portion is removed.

9. The mobile terminal of claim 1, wherein the screw-coupling hole and the screw-coupling groove are formed along an edge region of the display.

10. The mobile terminal of claim 1, wherein a printed circuit board is disposed between the front case and the rear case, and

wherein the metal frame is electrically connected to the display partially or wholly, and is electrically connected to a grounding portion of the printed circuit board.

11. The mobile terminal of claim 1, wherein the display is configured as an organic light emitting diode (OLED).

12. The mobile terminal of claim 1, wherein the display is bent in the form of a curved line, and

wherein the front case, the rear case and the metal frame are bent in correspondence to the shape of the display.

13. A mobile terminal, comprising:

a terminal body;

a display configured to output visual information to a front surface of the terminal body;

a frame coupled to a rear surface of the display, and integrated with the display by adhesion; and

a case forming an appearance of the terminal body partially or wholly, and to which the frame is detachably coupled such that the display is fixed to or separated from the case.

14. The mobile terminal of claim 13, wherein the case is provided with an accommodation portion for accommodating the display therein, and

wherein the frame is fixed to the case, using a screw coupled to the rear surface of the frame via one surface of the accommodation portion.

15. The mobile terminal of claim 14, wherein a boss portion protrudes from the rear surface of the frame, and

wherein the screw-coupling groove is formed at the boss portion.

16. The mobile terminal of claim 15, wherein a screw-coupling hole is formed at the case, and

wherein the boss portion is partially or wholly inserted into the screw-coupling hole.

17. The mobile terminal of claim 13, wherein the frame is formed in a ring shape along an edge region of the display, such that an opening is formed at a central part of the frame.

18. The mobile terminal of claim 17, further comprising a radiating sheet disposed at the opening, and configured to accelerate radiation of heat from the rear surface of the display.

19. The mobile terminal of claim 17, wherein the case comprises:

an accommodation portion configured to accommodate the display therein; and

a protruding portion protruding from one surface of the accommodation portion, and inserted into the opening.

20. The mobile terminal of claim 13, wherein the frame is formed to have rigidity smaller than that of at least one of the display and the case.
