Abstract

The present disclosure provides a mobile terminal including a window provided on one surface of a terminal body, and having a rear surface formed in a curved shape, a display mounted to the rear surface of the window and configured to output visual information through the window, and a separation-preventing member having one side coupled to the window and the other side coupled to the display, and configured to prevent the display from being separated from the window in a direction that the window and the display are spaced apart from each other.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a terminal body;
a window provided on the terminal body, the window having a rear surface formed in a curved shape;
a display having a front surface defining a first portion mounted to the rear surface of the window, the display configured to output visual information visible through the window; and
a separation-preventing member configured to prevent the display from being separated from the window in a direction away from the rear surface of the window, the separation-preventing member including:
a first portion coupled to the rear surface of the window; and
a second portion coupled to a second portion of the display.

2. The mobile terminal of claim 1 , wherein the separation-preventing member comprises:
a coupling portion coupled to the rear surface of the window;
a connecting portion extending from the coupling portion, the connecting portion covering at least one side surface of the display; and
a supporting portion extending from the connecting portion, the supporting portion supporting at least part of a rear surface of the display.

3. The mobile terminal of claim 2 , wherein the coupling portion has a curved shape corresponding to the curved shape of the rear surface of the window.

4. The mobile terminal of claim 2 , wherein the window comprises at least one key hole therein to accommodate a mechanical key which is manipulated in a pushing manner, and
wherein the coupling portion comprises at least one through hole located to correspond to the key hole, the through hole surrounding an entire outer periphery of the mechanical key.

5. The mobile terminal of claim 2 , further comprising a printed circuit board provided on a rear surface of the separation-preventing member,
wherein the connecting portion comprises a hole for insertion of a flexible printed circuit board extending from one side of the display, and
wherein the flexible printed circuit board extends through the hole and electrically connects the display to the printed circuit board.

6. The mobile terminal of claim 1 , wherein the window is curved along a first direction,
wherein the separation-preventing member comprises a first separation-preventing portion and a second separation-preventing portion provided at both end portions of the window in the first direction, respectively, and
wherein the first separation-preventing portion and the second separation-preventing portion extend along a second direction perpendicular to the first direction.

7. The mobile terminal of claim 6 , wherein the first separation-preventing portion and the second separation-preventing portion are connected to each other so as to cover a rear surface of the display.

8. The mobile terminal of claim 1 , wherein the display comprises:
a liquid crystal panel on which an image is output;
a backlight unit configured to emit light toward the liquid crystal panel; and
a reflection member disposed to surround at least a portion of a side surface of the backlight unit to reflect light leaked from the side surface of the backlight unit,
wherein the separation-preventing member is disposed to cover at least part of the reflection member.

9. The mobile terminal of claim 8 , wherein the separation-preventing member comprises:
a first coupling portion coupled to the rear surface of the window; and
a second coupling portion extending from the first coupling portion, the second coupling portion disposed to surround the display,
wherein a portion of the second coupling portion is integrally coupled with the reflection member by double injection molding.

10. The mobile terminal of claim 9 , further comprising a light absorbing layer provided on an inner side surface of the second coupling portion facing the liquid crystal panel,
wherein the light absorbing layer absorbs light leaked from the side surface of the liquid crystal panel.

11. The mobile terminal of claim 1 , wherein the display comprises:
a liquid crystal panel;
a backlight unit; and
a frame accommodating the backlight unit and the liquid crystal panel therein,
wherein the separation-preventing member is coupled to the frame.

12. The mobile terminal of claim 1 , further comprising a case accommodating the window therein,
wherein the separation-preventing member includes a coupling boss provided on a rear surface of the separation-preventing member for coupling the separation-preventing member to the case.

13. The mobile terminal of claim 12 , wherein the separation-preventing member comprises a base portion covering a rear surface of the display, and a bending portion bent from the base portion to overlap an inner side surface of the case,
wherein the bending portion includes stopping grooves into which stopping hooks provided on the inner side surface of the case are inserted.

14. The mobile terminal of claim 12 , further comprising a molding portion integrally coupled with the separation-preventing member,
wherein the molding portion includes the coupling boss.

15. The mobile terminal of claim 14 , wherein the molding portion comprises an accommodating portion providing a mounting space for a receiver that outputs sounds through an audio hole formed at the window.

16. The mobile terminal of claim 14 , further comprising an elastic member integrally coupled with the molding portion,
wherein the elastic member contacts the rear surface of the window to absorb an impact applied to the window.

17. The mobile terminal of claim 14 , wherein a coupling hole is located in a side surface of the case, and
wherein the case is coupled to the molding portion by a screw inserted through the coupling hole and coupled to the coupling boss.

18. The mobile terminal of claim 1 , wherein the window is curved along a lengthwise direction thereof,
wherein a printed circuit board is located at a rear surface of the separation-preventing member, the printed circuit board having a curved shape to correspond to the curved rear surface of the window,
wherein first and second guide rails are provided at both sides of the printed circuit board in a widthwise direction of the printed circuit board, and
wherein the first and second guide rails have a curved shape to correspond to the curved shape of the printed circuit board.

19. The mobile terminal of claim 18 , further comprising a reinforcing member coupled to each of the first and second guide rails to reinforce rigidities of the first and second guide rails.

20. The mobile terminal of claim 18 , further comprising a case having a curvature different from a curvature of the printed circuit board, the case having a boss in which a coupling member is inserted to couple the printed circuit board to the case,
wherein each of the first and second guide rails comprises an elastic member having a coupling hole through which the coupling member is inserted, the coupling hole being elastically deformable upon insertion of the coupling member.
