Abstract

Provided is a display apparatus. The display apparatus includes a display panel for displaying an image, a back cover mounted on a rear surface of the display panel, and a curvature adjustment unit mounted on the rear surface of the back cover to adjustment a curvature of the back cover according to user's manual manipulation.

First claim

What is claimed is:

1 . A display apparatus comprising:
a display panel for displaying an image; a back cover mounted on a rear surface of the display panel; and an adjustment unit positioned on a rear surface of the back cover, wherein the adjustment unit comprises a driving part and a curvature adjustment part, wherein the adjustment unit is capable of converting the back cover from a first state which is flat to a second state which is bent to have a curvature, wherein the curvature adjustment part has one side which is connected to the driving part and another side which is connected to the rear surface of the back cover.

2 . The display apparatus according to claim 1 , wherein the curvature adjustment part comprises;
a fixing part fixed on the rear surface of the back cover; and a connection part connected to the driving part.

3 . The display apparatus according to claim 1 , wherein the driving part is provided on the rear surface to be hidden by the back cover.

4 . The display apparatus according to claim 1 , wherein the curvature adjustment unit is arranged to move to a first position where the back cover is pressed by the curvature adjustment unit in a forward direction and a second position where the back cover is pulled by the curvature adjustment unit in a rear direction,
wherein the driving part pushes the curvature adjustment unit to the first position or pulls the curvature adjustment unit to the second position.

5 . The display apparatus according to claim 1 , wherein a pair of the curvature adjustment part is slid closer to or away from each other by the driving part.

6 . The display apparatus according to claim 1 , wherein the adjustment unit further comprises: a user's manipulation unit connected to the driving part to drive the driving part.

7 . The display apparatus according to claim 6 , wherein the user's manipulation unit is rotatably provided on the rear surface of the back cover.

8 . The display apparatus according to claim 6 , wherein the driving part is connected to both the user's manipulation and the curvature adjustment part.

9 . The display apparatus according to claim 6 , wherein the driving part comprises;
at least one rotation crank link-connected to the user's manipulation part, the at least one rotation crank being mounted on the rear surface of the back cover so that the at least one rotation crank is rotatable in a direction opposite to the rotation direction of the user's manipulation part when the user's manipulation part rotates, wherein the curvature adjustment part is link-connected to the at least one rotation crank.

10 . The display apparatus according to claim 9 , wherein a rotation guide slot is defined in the user's manipulation part in a longitudinal direction of the user's manipulation part, and
a crank link pin slid along the rotation guide slot and inserted into the rotation guide slot is disposed on the at least one rotation crank.

11 . The display apparatus according to claim 9 , wherein the user's manipulation part is mounted on the rear surface of the back cover through a pivot pin and is rotatable about the pivot pin.

12 . The display apparatus according to claim 11 , wherein
the at least one rotation crank is mounted on the rear surface of the back cover through a crank pivot pin and is rotatable about the crank pivot pin.

13 . The display apparatus according to claim 6 , wherein the user's manipulation part comprises;
a dial part rotatably disposed on the rear surface of the back cover, wherein the dial part is connected to the driving part.

14 . The display apparatus according to claim 6 , wherein the user's manipulation part is provided on the rear surface of the back cover to slide in a upward direction and a lower direction.

15 . The display apparatus according to claim 14 , wherein the driving part comprises; a sliding bearing provided at the curvature adjustment part,
wherein the sliding bearing slidably contact to the surface of the user's manipulation part.

16 . The display apparatus according to claim 14 , wherein the curvature adjustment part is slidably connected to the user's manipulation part,
wherein the driving part comprises a push bar contact with the curvature adjustment part when the user's manipulation part is slide in a lower direction, wherein the push bar pushes the curvature adjustment part to a position where the back cover is pressed by the curvature adjustment part in a forward direction.

17 . The display apparatus according to claim 16 , wherein the driving part further comprising; a link for connecting the push bar with the curvature adjustment part.

18 . The display apparatus according to claim 1 , wherein the curvature adjustment part is rotatably connected to the back cover,
wherein the back cover comprises; a sliding guide for guiding the curvature adjustment part slidably along the sliding guide.

19 . The display apparatus according to claim 18 , a user's manipulation part is protruded on the curvature adjustment part.

20 . The display apparatus according to claim 18 , wherein the sliding guide comprises at least one stopper is defined in the sliding guide,
wherein the stopper restricts the sliding of the curvature adjustment.
