Abstract

A display device includes a display panel, a mold frame at least partially surrounding the display panel, and a bracket at least partially overlapping the mold frame. Each of the mold frame and the bracket includes an electrically conductive material, and the mold frame and the bracket are electrically connected to each other.

First claim

What is claimed is:

1 . A display device, comprising:
a display panel; a mold frame at least partially surrounding the display panel; and a bracket at least partially overlapping the mold frame, wherein each of the mold frame and the bracket includes an electrically conductive material, and wherein the mold frame and the bracket are electrically connected to each other.

2 . The display device of claim 1 , further comprising a protective film disposed on the display panel,
wherein the display panel includes a cover region at least partially overlapping the protective film and an exposed region exposed by the protective film.

3 . The display device of claim 2 , wherein the protective film includes a protective base, and a protective base bonding layer disposed between the protective base and the display panel.

4 . The display device of claim 2 , further comprising a connection conductor disposed between the bracket and the mold frame,
wherein each of the mold frame and the bracket are directly connected to the connection conductor.

5 . The display device of claim 4 , wherein the connection conductor includes a conductive base, a first conductive bonding layer disposed between the conductive base and the mold frame, and a second conductive bonding layer disposed between the bracket and the conductive base.

6 . The display device of claim 4 , wherein the connection conductor includes a clamp.

7 . The display device of claim 4 , wherein the mold frame includes a main frame portion and a frame conductive layer disposed directly on a surface of the main frame portion, and
wherein the conductive layer is electrically connected to the bracket.

8 . The display device of claim 7 , wherein the conductive layer is formed on the main frame portion by coating, deposition, or thermal attachment.

9 . The display device of claim 7 , wherein the bracket includes an electrically conductive material.

10 . The display device of claim 7 , wherein the bracket includes a main bracket portion and a bracket conductive layer disposed inside of the main bracket portion, and
wherein the connection conductor is connected to the frame conductive layer and the bracket conductive layer.

11 . The display device of claim 10 , wherein the main bracket portion is further disposed on a lower surface of the display panel.

12 . The display device of claim 7 , wherein the main frame portion includes a first frame portion disposed on a side surface of the display panel, and a second frame portion connected to the first frame portion and disposed on the surface of the display panel.

13 . The display device of claim 12 , wherein the conductive layer is disposed directly on the first frame portion.

14 . The display device of claim 13 , wherein the conductive layer further includes a plurality of conductive patterns spaced apart from each other along the second frame portion.

15 . The display device of claim 4 , wherein the mold frame includes an electrically conductive material dispersed therein.

16 . The display device of claim 4 , wherein the bracket is electrically connected to a set ground wire.

17 . The display device of claim 2 , further comprising a cover window disposed between the protective film and the display panel, and a light blocking pattern disposed directly on an edge of the cover window,
wherein the light blocking pattern includes an electrically conductive material.

18 . A display device, comprising:
a display panel in which a folding region, a first non-folding region located on one side of the folding region, and a second non-folding region located on the other side of the folding region are defined; a first mold frame disposed adjacent to the first non-folding region of the display panel; a second mold frame disposed adjacent to the second non-folding region of the display panel; a first bracket at least partially overlapping the first mold frame; and a second bracket at least partially overlapping the second mold frame, wherein each of the first mold frame and the second mold frame includes a first electrically conductive material, wherein each of the first bracket and the second bracket includes a second electrically conductive material that is either different from or the same as the first electrically conductive material, wherein the first mold frame and the first bracket are electrically connected to each other, and wherein the second mold frame and the second bracket are electrically connected to each other.

19 . The display device of claim 18 , further comprising a protective film disposed on the display panel,
wherein the display panel includes a cover region at least partially overlapping the protective film and an exposed region exposed by the protective film.

20 . The display device of claim 19 , further comprising a first connection conductor disposed between the first bracket and the first mold frame, and a second connection conductor disposed between the second bracket and the second mold frame,
wherein the first mold frame and the first bracket are directly connected to the first connection conductor, and wherein the second mold frame and the second bracket are each directly connected to the second connection conductor.

21 . The display device of claim 20 , wherein each of the first bracket and the second bracket is electrically connected to a set ground wire.
