Display device
A display device includes: a panel assembly including a display panel; a bracket to which the panel assembly is attached; and a buffer layer between the panel assembly and the bracket, and the buffer layer includes: a first portion having a first elastic modulus; and a second portion surrounded by the first portion and having a second elastic modulus that is less than the first elastic modulus.
1. A display device comprising:
a panel assembly comprising a display panel;
a bracket to which the panel assembly is attached; and
a buffer layer between the panel assembly and the bracket,
wherein the buffer layer comprises:
a first portion having a first elastic modulus; and
a second portion surrounded by the first portion and having a second elastic modulus that is less than the first elastic modulus.
2. The display device of claim 1 , wherein the first portion is located along an edge of the panel assembly.
3. The display device of claim 1 , wherein
the panel assembly comprises a display area to display an image, and a non-display area around the display area, and
the first portion overlaps with the non-display area.
4. The display device of claim 3 , wherein the second portion overlaps with the display area.
5. The display device of claim 1 , wherein the first elastic modulus is 1000 MPa or more, and the second elastic modulus is 5 MPa or less.
6. The display device of claim 1 , wherein the first portion comprises a polymer or a metal.
7. The display device of claim 1 , wherein the second portion comprises a foam resin.
8. The display device of claim 1 , wherein the buffer layer further comprises a third portion surrounded by the second portion and having a third elastic modulus that is less than the second elastic modulus.
9. The display device of claim 1 , wherein the panel assembly further comprises a cover window on the display panel, and at least a portion of the cover window is flexible.
10. The display device of claim 9 , wherein the panel assembly further comprises an anti-reflective layer between the display panel and the cover window.
11. The display device of claim 1 , wherein the panel assembly further comprises a bottom chassis between the display panel and the buffer layer.
12. The display device of claim 11 , wherein the bottom chassis is attached to the bracket by the buffer layer.
13. The display device of claim 11 , wherein the panel assembly further comprises a cushion layer between the display panel and the bottom chassis.
14. A display device comprising:
a panel assembly comprising a display panel and a cover window on the display panel;
a bracket below the panel assembly; and
a buffer layer between the panel assembly and the bracket and comprising a first portion and a second portion,
wherein the first portion has a rigidity that is greater than a rigidity of the second portion, the first portion being located further outward from a center of the panel assembly than the second portion.
15. The display device of claim 14 , wherein the first portion surrounds the second portion.
16. The display device of claim 14 , wherein the first portion has an elastic modulus that is 1000 MPa or more, and the second portion has an elastic modulus that is 5 MPa or less.
17. The display device of claim 14 , wherein the first portion comprises a polymer or a metal.
18. The display device of claim 14 , wherein the second portion comprises a foam resin.
19. The display device of claim 14 , wherein the buffer layer further comprises a third portion having a rigidity that is less than the rigidity of the second portion, the third portion being closer to the center of the panel assembly than the second portion.
20. The display device of claim 14 , wherein
the panel assembly further comprises a bottom chassis below the display panel, and
the bottom chassis is attached to the bracket by the buffer layer.
