Abstract

A display device according to the present invention comprises: a display module including a display panel; at least one pair of first and second spacers disposed at the rear of the display module and fixed to the display module; and a wall mount assembly disposed at the rear of the back cover and fastened to the first and second spacers while allowing movements of the first and second spacers, wherein the wall mount assembly comprises: a fixing part fixed to a fixed object; a frame having a pair of first and second tilting holes into which the first and second spacers are respectively inserted, and which guides moving paths of the first and second spacers, and a locking part which selectively restricts the moving paths of the first and second spacers inserted into the first and second tilting holes; and a link connecting the fixing part and the frame to each other.

First claim

The invention claimed is:

1. A display device comprising:
a display module including a display panel;
at least one pair of first and second spacers disposed at the rear of the display module and fixed to the display module; and
a wall mount assembly disposed at the rear of a back cover and fastened to the first and second spacers while allowing movements of the first and second spacers,
wherein the wall mount assembly includes:
a fixing part fixed to a fixed object;
a frame having a pair of first and second tilting holes into which the first and second spacers are respectively inserted, and which guides moving paths of the first and second spacers, and a locking part for selectively restricting the moving paths of the first and second spacers inserted into the first and second tilting holes; and
a link connecting the fixing part and the frame to each other.

2. The display device of claim 1 , wherein each of the first and second tilting holes includes:
an inlet portion provided to allow the first and second spacers to be inserted into and released from the inlet portion; and
a guide portion disposed under the inlet portion, in which the first and second spacers inserted through the inlet portion is seated, and
wherein the locking part includes a blocking part rotatably fastened to the frame and disposed between the inlet portion and the guide portion.

3. The display device of claim 2 , wherein each of the first and second tilting holes includes a link portion connecting the inlet portion and the guide portion, and the blocking part is disposed to correspond to the link portion.

4. The display device of claim 1 , wherein one end and the other end of the locking part are rotatably fastened to the frame.

5. The display device of claim 2 , wherein each of the first and second spacers includes:
a spacer head having a first diameter; and
a spacer neck extending from the spacer head and having a second diameter less than the first diameter,
wherein the inlet portion has a hole area greater than the first diameter, and
wherein the guide portion has a hole area less than the first diameter and greater than the second diameter.

6. The display device of claim 5 , wherein the guide portion includes:
a seating part; and
first and second extension parts extending from the seating part in one direction,
wherein the first and second extension parts extend in a reverse direction from the seating part.

7. The display device of claim 6 , wherein an extension line extending in the extension direction of the guide portion and a horizontal line extending in a horizontal direction intersect each other, and an angle formed by the extension line and the horizontal line is a tilt angle.

8. The display device of claim 6 , wherein the guide portions of the first and second tilting holes extend in a straight line form in a tangent direction of a virtual arc passing through centers of the guide portions of the first and second tilting holes or extend in a curved form in an extension direction of the virtual arc.

9. The display device of claim 8 , wherein the virtual arc is convexly curved upward or convexly curved downward.

10. The display device of claim 8 , wherein the virtual arc is a part of the circumference of a circle having a virtual center point,
wherein the virtual center point is positioned on a reference line crossing the center of the frame in the vertical direction.

11. The display device of claim 1 , wherein the first and second tilting holes are symmetrical with respect to a reference line crossing the center of the frame in the vertical direction.

12. The display device of claim 1 , further comprising an auxiliary locking part fixed to the fixing part through one end and having predetermined elasticity,
wherein the other end of the auxiliary locking part extends downward from one end of the auxiliary locking part and is disposed to overlap at least a part of the frame in a back-and-forth direction.

13. The display device of claim 1 , wherein the display module includes:
a module cover disposed at the rear of the display panel;
the back cover disposed at the rear of the module cover and having first and second open holes disposed to correspond to the first and second spacers; and
a wall mount plate disposed between the module cover and the back cover and fixed to the module cover,
wherein the first and second spacers are fixed to the wall mount plate through the first and second open holes, respectively, at the rear of the back cover.

14. The display device of claim 13 , wherein the back cover includes a forming part overlapping the wall mount plate, and at least a part of the wall mount assembly is inserted into the forming part.

15. The display device of claim 1 , wherein the link includes a first link and a second link rotatably coupled to each other based on a virtual first axis extending in the vertical direction,
wherein one end of the first link is rotatably coupled to the fixing part based on a virtual second axis extending in the vertical direction, and one end of the second link is rotatably coupled to the frame based on a virtual third axis extending in the vertical direction.

16. The display device of claim 15 , wherein the first link includes an accommodating recess capable of accommodating at least a part of the second link.
