Abstract

A display device includes a display panel including a front surface, a rear surface, and a folding axis; a support member disposed on the rear surface of the display panel, the support member including a first support member and a second support member; a hinge connected to the first support member and the second support member to each other; a hinge cover disposed over the hinge; a first rear cover disposed on a rear surface of the first support member; a second rear cover disposed on a rear surface of the second support member; a first blocking member disposed on a first cover surface of the first rear cover; and a second blocking member disposed on a second cover surface of the second rear cover.

Claims (72)

1. A display device comprising:

a display panel including:

a rear surface opposite to the front surface of the display panel; and

a folding axis;

a support member disposed on the rear surface of the display panel, the support member including:

a first support member disposed on a side of the folding axis; and

a second support member separated from the first support member and disposed on another side of the folding axis;

a hinge connected to the first support member and the second support member;

a hinge cover disposed over the hinge, the hinge cover including:

a front surface facing the hinge; and

a rear surface opposite to the front surface of the hinge cover;

a first rear cover disposed on a rear surface of the first support member, the first rear cover including a first cover surface that covers a first area of the rear surface of the hinge cover in an unfolded state;

a second rear cover disposed on a rear surface of the second support member, the second rear cover including a second cover surface that covers a second area of the rear surface of the hinge cover in the unfolded state;

a first blocking member attached to the first cover surface of the first rear cover, the first blocking member including a plurality of first protrusions; and

a second blocking member attached to the second cover surface of the second rear cover, the second blocking member including a plurality of second protrusions.

2. The display device of claim 1 , wherein

the first blocking member includes a first plate including a surface on which the plurality of first protrusions are disposed, and

the second blocking member includes a second plate including a surface on which the plurality of second protrusions are disposed.

3. The display device of claim 2 , further comprising:

a first adhesive member disposed between another surface of the first plate and the first cover surface; and

a second adhesive member disposed between another surface of the second plate and the second cover surface.

4. The display device of claim 1 , wherein the plurality of first protrusions and the plurality of second protrusions have a diameter equal to or less than about 0.5 mm.

5. The display device of claim 1 , wherein

the plurality of first protrusions and the plurality of second protrusions form a plurality of rows in a direction, and

protrusions of a first row among the plurality of rows and protrusions of a second row among the plurality of rows are disposed alternately with each other.

6. The display device of claim 1 , wherein

a distance between the plurality of first protrusions is equal to or less than a distance between the rear surface of the hinge cover and the first cover surface, and

a distance between the plurality of second protrusions is equal to or less than a distance between the rear surface of the hinge cover and the second cover surface.

7. The display device of claim 6 , wherein each of the distance between the plurality of first protrusions and the distance between the plurality of second protrusions is equal to or less than about 1.0 mm.

8. The display device of claim 1 , wherein

the first blocking member covers a gap between the rear surface of the hinge cover and the first cover surface, and

the second blocking member covers a gap between the rear surface of the hinge cover and the second cover surface.

9. The display device of claim 8 , wherein

the plurality of first protrusions have a height equal to or less than a distance between the rear surface of the hinge cover and the first cover surface, and

the plurality of second protrusions have a height equal to or less than a distance between the rear surface of the hinge cover and the second cover surface.

10. The display device of claim 9 , wherein the plurality of first protrusions and the plurality of second protrusions have a height equal to or less than about 1.5 mm.

11. The display device of claim 1 , wherein

the first blocking member is disposed between the rear surface of the hinge cover and the first cover surface, and

the second blocking member is disposed between the rear surface of the hinge cover and the second cover surface.

12. The display device of claim 1 , wherein

the first cover surface and the second cover surface include curved surfaces, respectively, and

the first blocking member and the second blocking member are curved corresponding to shapes of the curved surfaces of the first cover surface and the curved surface of the second cover surface, respectively.

13. The display device of claim 12 , wherein

the rear surface of the hinge cover has a convex shape, and

the first cover surface and the second cover surface have a concave shape corresponding to the convex shape of the rear surface of the hinge cover.

14. The display device of claim 1 , wherein the first blocking member and the second blocking member include at least one of silicon or plastic.

15. The display device of claim 1 , wherein the rear surface of the hinge cover is exposed between the first rear cover and the second rear cover in a folded state.

16. A display device comprising:

a display panel including:

a folding area;

a first non-folding area disposed on a side of the folding area; and

a second non-folding area disposed on another side of the folding area;

a first cover disposed in the folding area;

a second cover disposed in the first non-folding area, the second cover including a side adjacent to the first cover and separated from the first cover;

a third cover disposed in the second non-folding area, the third cover including a side adjacent to the first cover and separated from the first cover;

a first blocking member attached to the side of the second cover and covering a gap between the first cover and the side of the second cover; and

a second blocking member attached to the side of the third cover and covering a gap between the first cover and the side of the third cover.

17. The display device of claim 16 , wherein each of the first blocking member and the second blocking member includes a plate and a plurality of protrusions protruding from a surface of the plate.

18. The display device of claim 17 , wherein the plurality of protrusions have a diameter equal to or less than about 0.5 mm.
