Abstract

A display apparatus includes a display panel configured to display an image; a plate on a rear surface of the display panel; a rear structure on a rear surface of the plate and configured to support the display panel; a vibration member configured to vibrate the plate; and a first supporting member between a periphery of the plate and the rear structure.

Claims (42)

1. A display apparatus, comprising:

a display panel configured to display an image;

a plate on a rear surface of the display panel;

a rear structure on a surface of the plate opposite to the display panel;

a vibration member configured to vibrate the plate and on a surface of the plate facing the display panel;

an adhesive member disposed between the display panel and the vibration member; and

a first supporting member between a periphery of the plate and the rear structure,

wherein:

the first supporting member does not overlap the vibration member; and

the adhesive member has a higher rigidity than that of the first supporting member.

2. The display apparatus according to claim 1 , wherein the first supporting member is in contact with at least two peripheries of the surface of the plate opposite to the display panel.

3. The display apparatus according to claim 1 , wherein the vibration member is on a first surface of the plate, and the first supporting member is on a second surface of the plate opposite to the first surface.

4. The display apparatus according to claim 1 , wherein the vibration member includes first portions having a piezoelectric property, and second portions between the first portions having flexibility.

5. The display apparatus according to claim 1 , wherein the vibration member is spaced apart from the rear surface of the display panel, or

wherein the vibration member includes a composite film.

6. The display apparatus according to claim 1 , wherein the vibration member is between the plate and the display panel.

7. The display apparatus according to claim 1 , wherein the vibration member is on a front surface of the plate.

8. The display apparatus according to claim 1 , wherein the vibration member includes a plurality of first portions and a plurality of second portions, and the plurality of the first portions and the plurality of the second portions respectively is disposed on a same plane in parallel.

9. The display apparatus according to claim 1 , wherein:

the vibration member comprises first portions and one or more second portions;

a first one of the first portions is spaced apart from a second one of the first portions along a direction perpendicular to a thickness direction of the vibration member; and

one of the one or more second portions is disposed between the first one and the second one of the first portions.

10. A display apparatus, comprising:

a display panel configured to display an image;

a rear structure on a rear surface of the display panel;

a plurality of sound generating modules between the display panel and the rear structure and configured to vibrate the display panel to generate sound; and

an adhesive member between the display panel and the plurality of sound generating modules,

wherein each of the plurality of sound generating modules includes:

a plate between the display panel and the rear structure;

a vibration member configured to vibrate the plate; and

a supporting member between a periphery of the plate and the rear structure, and

wherein:

the adhesive member is between the vibration member and the display panel;

the supporting member does not overlap the vibration member; and

the adhesive member has a higher rigidity than that of the supporting member.

11. The display apparatus according to claim 10 , wherein the vibration member is on a first surface of the plate, and wherein the supporting member is on a second surface of the plate opposite to the first surface.

12. The display apparatus according to claim 10 , wherein the vibration member includes first portions having a piezoelectric property, and second portions between the first portions having flexibility.

13. The display apparatus according to claim 10 , wherein the vibration member includes a composite film.

14. The display apparatus according to claim 10 , wherein the vibration member is between the plate and the display panel.

15. The display apparatus according to claim 10 , wherein the vibration member is on a front surface of the plate.

16. The display apparatus according to claim 10 , wherein the vibration member includes a plurality of first portions and a plurality of second portions, and the plurality of the first portions and the plurality of the second portions respectively are disposed on a same plane in parallel.

17. The display apparatus according to claim 10 , wherein the adhesive member is between a center portion of the vibration member and the display panel.
