Display device
A display device includes: a display panel that displays an image, a frame portion attached to a rear surface of the display panel, where the frame portion supports the display panel and includes at least one protrusion, and a vibration unit disposed between the frame portion and the display panel, where the vibration unit overlaps the protrusion and vibrates the display panel.
1 . A display device, comprising:
a display panel that displays an image;
a frame portion attached to a rear surface of the display panel, wherein the frame portion supports the display panel and includes at least one protrusion; and
a vibration unit disposed between the frame portion and the display panel, wherein the vibration unit overlaps the protrusion and vibrates the display panel,
wherein the vibration unit includes:
a first plate disposed between the frame portion and the display panel and within the at least one protrusion, and
a second plate connected to the frame portion, wherein the second plate overlaps the at least one protrusion of the frame portion and covers the at least one protrusion.
2 . The display device of claim 1 , wherein the frame portion is integrally formed as a whole.
3 . The display device of claim 1 , wherein the frame portion covers the vibration unit and entirely overlaps the display panel.
4 . The display device of claim 1 , wherein the frame portion includes iron.
5 . The display device of claim 1 , further comprising:
an adhesive layer interposed between the vibration unit and the display panel.
6 . The display device of claim 5 , wherein the vibration unit contacts the rear surface of the display panel through the adhesive layer.
7 . The display device of claim 1 , wherein the display panel includes:
a substrate; and
a display element layer disposed on the substrate.
8 . The display device of claim 7 , wherein the frame portion is disposed under the substrate opposite to the display element layer and is attached to the substrate.
9 . The display device of claim 1 , wherein the vibration unit includes:
a magnetic circuit disposed between the first plate and the frame portion and within the at least one protrusion; and
a coil that surrounds the first plate.
10 . The display device of claim 9 , wherein the second plate includes a same material as the frame portion.
11 . The display device of claim 10 , wherein the second plate includes iron.
12 . A display device, comprising:
a display panel that displays an image;
a frame portion attached to a rear surface of the display panel, wherein the frame portion supports the display panel and includes at least one protrusion and a supporting portion coupled to the at least one protrusion; and
a vibration unit disposed between the frame portion and the display panel, wherein the vibration unit overlaps the protrusion and vibrates the display panel,
wherein the at least one protrusion covers the vibration unit and a thickness of the at least one protrusion along an entire length of the at least one protrusion is greater than a thickness of the supporting portion.
13 . The display device of claim 12 , wherein the at least one protrusion and the supporting portion are rotationally coupled.
14 . The display device of claim 12 , further comprising:
a plate disposed between the frame portion and the display panel and within the at least one protrusion;
a magnetic circuit disposed between the plate and the frame portion and within the at least one protrusion; and
a coil that surrounds the plate.
15 . The display device of claim 12 , further comprising:
a mold that connects the at least one protrusion and the supporting portion.
16 . The display device of claim 15 , wherein the supporting portion is spaced apart from the at least one protrusion and is coupled to the at least one protrusion through the mold.
17 . The display device of claim 15 , wherein the mold includes an insulating material.
18 . The display device of claim 15 , wherein the supporting portion is rotationally coupled to the mold.
