Abstract

A display apparatus having a display module which may be selectively set to a flat surface state or a curved surface state. The display apparatus having a display module includes a bendable display panel configured to display images, a first frame provided at a front of the display panel, and a second frame provided at a back of the display panel. The second frame includes a first bracket positioned at a back of the display panel, and a second bracket provided to be slidable with respect to the first bracket.

First claim

What is claimed is:

1. A display apparatus comprising: a display module including: a display panel configured to display images, the display panel being bendable; a first frame provided in front of the display panel; a second frame provided behind the display panel; and a connecting member configured to connect the first frame to the second frame such that the first frame and the second frame move relative to each other to bend the display panel, wherein the second frame comprises: a first bracket positioned behind the display panel; and a second bracket provided to be slidable with respect to the first bracket, wherein the connecting member is fixed to the second frame while passing through the first frame.

2. The display apparatus according to claim 1 , wherein the connecting member comprises:
a head;
a first support integrally formed at a lower end of the head; and
a second support extending from a lower end of the first support, wherein the second support is provided with threads.

3. The display apparatus according to claim 2 , wherein the first frame is provided with a fastening hole configured to receive, in a sliding manner, the first support of the connecting member.

4. The display apparatus according to claim 3 , wherein the fastening hole is a long hole formed in the first frame.

5. The display apparatus according to claim 2 , wherein the first bracket is provided with a connecting recess to fix the second support of the connecting member.

6. The display apparatus according to claim 5 , wherein the first bracket comprises a cover provided with a guide allowing the second bracket to slide thereon.

7. The display apparatus according to claim 5 , wherein the connecting member moves according to a movement of the first bracket.

8. The display apparatus according to claim 5 , wherein:
the second bracket is coupled to a slide screw such that the second bracket is slidable between the first bracket and the guide; and
the slide screw comprises:
a head;
a first support integrally formed at a lower end of the head; and
a second support extending from a lower end of the first support,
wherein the second support is provided with threads.

9. The display apparatus according to claim 1 , wherein the display panel comprises an organic light emitting diode panel.

10. The display apparatus according to claim 1 , further comprising a driving apparatus positioned at a back of the display module such that the display module is deformable from one state to another state from a plurality of states, wherein the plurality of states comprise a flat surface state and a curved surface state.

11. The display apparatus according to claim 10 , further comprising a base member positioned at a back of the display module to support the driving apparatus.

12. The display apparatus according to claim 11 , wherein the driving apparatus comprises:
a driver installed on the base member and configured to generate a driving force;
moving members moved by the driver in opposite directions with respect to each other; and
rotating members which are rotatably connected to the moving members so as to rotate both ends of the display module in forward and backward directions.

13. The display apparatus according to claim 12 ,
wherein the moving members further comprise a fine adjustment apparatus configured to finely adjust left and right balance of the display module.

14. The display apparatus according to claim 12 ,
wherein the moving members further comprise a guide configured to guide movement of the moving members.

15. The display apparatus according to claim 12 , further comprising:
a sensor configured to measure a moving distance of the moving members.

16. The display apparatus according to claim 12 , further comprising:
a shield that is positioned behind the display module, rotates together when both ends of the display module move forward, and covers a space between the display module and the base member.
