Abstract

A display apparatus includes: a display panel configured to display an image, at least one supporting member on a rear surface of the display panel, the at least one supporting member defining a groove, at least one sound generation device adjacent to the display panel, and a wiring, accommodated into the groove, configured to transfer a signal to the at least one sound generation device.

Claims (95)

1. A display apparatus, comprising:

a display panel configured to display an image;

at least one supporting member on a rear surface of the display panel, the at least one supporting member defining a groove;

at least one sound generation device on the rear surface of the display panel, the at least one sound generation device being configured to vibrate the display panel to generate sound toward a front portion of the display panel; and

a wiring, accommodated into the groove, configured to transfer a signal to the at least one sound generation device.

2. The display apparatus of claim 1 , wherein:

the at least one supporting member comprises:

a first supporting member; and

a second supporting member closer to the display panel than the first supporting member; and

the groove is in the second supporting member.

3. The display apparatus of claim 2 , wherein:

the first supporting member comprises a hole; and

the wiring extends to a rear surface of the first supporting member through the hole.

4. The display apparatus of claim 3 , wherein:

a rear cover is on the rear surface of the first supporting member; and

the wiring extending to the rear surface of the first supporting member is covered by the rear cover.

5. The display apparatus of claim 3 , wherein:

a rigid bar and a rear cover are on the rear surface of the first supporting member; and

the rigid bar and the wiring extending to the rear surface of the first supporting member are covered by the rear cover.

6. The display apparatus of claim 3 , wherein:

a driving circuit unit configured to transfer the signal to the wiring is on a rear surface of the first supporting member; and

the wiring is electrically connected to the driving circuit unit.

7. The display apparatus of claim 6 , wherein:

a rear cover is on the rear surface of the first supporting member; and

the driving circuit unit is covered by the rear cover.

8. The display apparatus of claim 1 , wherein:

the at least one sound generation device comprises two sound generation devices; and

the groove is between the two sound generation devices.

9. The display apparatus of claim 1 , wherein the at least one sound generation device is configured to vibrate the display panel to generate:

sound having a middle-high-pitched sound band; and

sound having a low-pitched sound band.

10. The display apparatus of claim 1 , further comprising a partition on the rear surface of the display panel and in a periphery of the display panel.

11. A display apparatus, comprising:

a display panel configured to display an image, the display panel comprising:

a first region;

a second region; and

a third region;

at least one supporting member on a rear surface of the display panel;

at least one sound generation device configured to vibrate the display panel to generate sound, the at least one sound generation device being in at least one of the first region, the second region, and the third region; and

a wiring between the display panel and the at least one supporting member, the wiring being configured to transfer a signal to the at least one sound generation device.

12. The display apparatus of claim 11 , wherein:

the at least one supporting member comprises:

a first supporting member; and

a second supporting member closer to the display panel than the first supporting member; and

the second supporting member comprises a groove accommodating the wiring.

13. The display apparatus of claim 12 , wherein:

the first supporting member comprises a hole; and

the wiring extends to a rear surface of the first supporting member through the hole.

14. The display apparatus of claim 13 , wherein:

a rear cover is on the rear surface of the first supporting member; and

the wiring extending to the rear surface of the first supporting member is covered by the rear cover.

15. The display apparatus of claim 12 , wherein:

a driving circuit unit configured to transfer the signal to the wiring is on a rear surface of the first supporting member; and

the wiring is connected to the driving circuit unit.

16. The display apparatus of claim 15 , wherein:

a rear cover is on the rear surface of the first supporting member; and

the wiring connected to the driving circuit unit is covered by the rear cover.

17. The display apparatus of claim 12 , wherein:

a rigid bar is on a rear surface the first supporting member; and

the wiring is under the rigid bar.

18. The display apparatus of claim 11 , wherein:

the first region is a left region of the display panel;

the second region is a right region of the display panel; and

the third region is a center region of the display panel.

19. The display apparatus of claim 11 , wherein at least one sound generation device or a pair of sound generation devices is in each of the first region and the second region.

20. The display apparatus of claim 11 , wherein:

sound having a middle-high-pitched sound band is generated in each of the first region and the second region; and

sound having a low-pitched sound band is generated in the third region.

21. The display apparatus of claim 11 , further comprising:

at least one first partition on the rear surface of the display panel between the first region and the second region; and

at least one second partition between the second region and the third region.

22. The display apparatus of claim 21 , further comprising a third partition in a periphery of the display panel, the third partition comprising a bent part that is bent in a direction toward the at least one sound generation device.

23. The display apparatus of claim 21 , further comprising:

a third partition in a periphery of the display panel, the third partition comprising a bent part disposed on at least one first side of four sides of the third partition and bent in a direction toward the at least one sound generation devices; and at least one protrusion portion on at least one of second sides vertical to the first sides.

24. The display apparatus of claim 11 , wherein two sound generation devices or a pair of sound generation devices is in each of at least two of the first region, the second region, and the third region.

25. A display apparatus, comprising:

a display panel configured to display an image;

a first supporting member and a second supporting member on a rear surface of the display panel;

at least one sound generation device on the rear surface of the display panel, the at least one sound generation device being configured to vibrate the display panel to generate sound;
