Abstract

According to an aspect of the present disclosure, a display device includes a display panel configured to display an image; a corrugated panel on a rear surface of the display panel, the corrugated panel comprising a first skin layer, a second skin layer, and a core layer between the first skin layer and the second skin layer; and a back cover that encloses the display panel and the corrugated panel, wherein at least one of the first skin layer or the second skin layer comprises an opening through a thickness of the at least one of the first skin layer or the second skin layer to improve the appearance quality of the display device.

Claims (28)

1 . A display device, comprising:

a display panel configured to display an image;

a corrugated panel on a rear surface of the display panel, the corrugated panel comprising a first skin layer, a second skin layer, and a core layer between the first skin layer and the second skin layer; and

a back cover that encloses the display panel and the corrugated panel,

wherein at least one of the first skin layer or the second skin layer comprises an opening through a thickness of at least one of the first skin layer or the second skin layer,

wherein a thickness of a first portion of the corrugated panel in a first area is different from a thickness of a second portion of the corrugated panel in a second area, and at least one opening is in a third area of the corrugated panel that is between the first area and the second area, and

wherein a fourth portion of the corrugated panel in a fourth area that is at a center of the first area includes at least one groove through the first skin layer, the second skin layer, and the core layer in the fourth area.

2 . The display device according to claim 1 , wherein a distance between the first skin layer and the second skin layer in the first area is different from a distance between the first skin layer and the second skin layer in the second area.

3 . The display device according to claim 1 , wherein the core layer comprises a plurality of ridges and a plurality of grooves that are alternately disposed, each of the plurality of ridges protruding from a centerline of the core layer to the second skin layer and each of the plurality of grooves protruding from the centerline of the core layer to the first skin layer.

4 . The display device according to claim 3 , wherein a thickness of the core layer in the first area is different from a thickness of the core layer in the second area.

5 . The display device according to claim 1 , wherein the opening comprises at least one rectangular opening in the third area along one axial direction in the third area.

6 . The display device according to claim 1 , wherein the opening comprises a plurality of rectangular openings in the third area, each rectangular opening extending along a different axial direction from at least another rectangular opening from the plurality of rectangular openings in the third area.

7 . The display device according to claim 1 , wherein the opening comprises at least one circular opening in the third area that extends along one axial direction.

8 . The display device according to claim 1 , wherein the opening comprises a plurality of circular openings, each circular opening extending along a different axial direction from at least another circular opening from the plurality of circular openings in the third area.

9 . The display device according to claim 1 , wherein the opening comprises at least one “V” shaped opening in the third area that extends along at least one axial direction.

10 . The display device according to claim 1 , wherein the opening comprises at least one “S” shaped opening in the third area that extends along at least one axial direction in the third area.

11 . A display device comprising:

a display panel configured to display an image;

a back cover including a cavity; and

a corrugated panel between the display panel and the back cover such that the display panel and the corrugated panel are disposed in the cavity of the back cover,

wherein the corrugated panel includes an opening through at least a portion of the corrugated panel, a first skin layer, a second skin layer and a core layer between the first skin layer and the second skin layer, the core layer including a plurality of alternating first protrusions and second protrusions where each first protrusion contacts the first skin layer and each second protrusion contacts the second skin layer,

wherein a thickness of a first portion of the corrugated panel in a first area is different from a thickness of a second portion of the corrugated panel in a second area, and the opening is in a portion of the first skin layer in a third area of the corrugated panel that is between the first area and the second area, and

wherein a fourth portion of the corrugated panel in a fourth area that is at a center of the first area includes at least one groove through the first skin layer, the second skin layer, and the core layer in the fourth area.

12 . The display device of claim 11 , wherein a distance between the first skin layer and the second skin layer in the first area is different from a distance between the first skin layer and the second skin layer in the second area.

13 . The display device of claim 12 , further comprising:

a cohesion member configured to couple the display panel to the back cover, the cohesion member between the back cover and the display panel in the fourth area and between the first skin layer and the display panel in the first area.

14 . The display device of claim 11 , wherein a thickness of a first portion of the corrugated panel in the first area is less than a thickness of a second portion of the corrugated panel in the second area.

15 . The display device of claim 11 , wherein the opening comprises one of at least one rectangular opening in a plan view of the display device, at least one circular opening in the plan view of the display device, at least one “V” shaped opening in the plan view of the display device, or at least one “S” shaped opening in the plan view of the display device.
