Abstract

A display device comprises: a display module that outputs an image; a drive IC positioned at the rear surface of one end of the display module; an inner sheet disposed on the rear surface of the display module to form a first gap; a cover bottom disposed on the rear surface of the inner sheet to form a second gap; and a middle cabinet that covers the circumferences of the display module, the inner sheet, and the cover bottom and forms a side exterior, wherein the inner sheet includes: a first region protruding in a direction toward the rear surface at a position corresponding to the drive IC; and a plurality of holes formed in the first region, wherein the holes extend vertically and are spaced apart from each other in a horizontal direction. The display device can be used in a form desired by a user since the display module can be transformed into a flat state or a bent state.

Claims (66)

1 . A display device comprising:

a display module configured to output an image;

a drive integrated circuit (IC) coupled to the display module;

a cover bottom located to form rear gaps on a rear surface of the inner sheet; and

a middle cabinet covering perimeters of the display module, the inner sheet, and the cover bottom to form a lateral outer appearance,

wherein the first region of the inner sheet protrudes toward a rear side and includes a plurality of first holes extending in a vertical direction and spaced apart from each other in a horizontal direction, and

wherein the front gaps include:

a first front gap formed between the display module and the first region of the inner sheet, wherein the first front gap is sized to permit positioning of the drive IC,

a second front gap formed between the display module and the second region of the inner sheet, and

a third front gap formed between the display module and the third region of the inner sheet,

wherein the first front gap is larger than the second front gap and the third front gap,

wherein the inner sheet includes a plurality of slits formed in an end of the inner sheet,

wherein the middle cabinet includes an exposed portion exposed around a lateral surface and a fastener extending between the display module and the inner sheet from the exposed portion, and

wherein the display device further includes an adhesive tape located in the plurality of slits and configured to fasten the fastener to the cover bottom.

2 . The display device of claim 1 , wherein the second and third front gaps are smaller than the rear gaps between the cover bottom and the second and third regions of the inner sheet.

3 . The display device of claim 1 , wherein the second region is located in a central portion of the inner sheet in the horizontal direction, and

wherein the inner sheet includes a plurality of rigid beads individually formed in the second region, and separately extending in the horizontal direction, and spaced apart from each other in the vertical direction.

4 . The display device of claim 3 , wherein the third region is located between the second region and an end in the horizontal direction, and

wherein the inner sheet further includes a plurality of second holes formed in the third region.

5 . The display device of claim 1 , wherein the middle cabinet includes:

the fastener extending inward from the exposed portion and including a first hook,

wherein the inner sheet has an end including a second hook coupled to the first hook.

6 . The display device of claim 1 , wherein the middle cabinet includes:

the fastener extending inward from the exposed portion, and

the fastener is located between the inner sheet and the cover bottom.

7 . The display device of claim 6 , wherein a front surface of the fastener is coupled to the rear surface of the inner sheet by using the adhesive tape, and

a rear surface of the fastener is coupled to a front surface of the cover bottom by using the adhesive tape.

8 . The display device of claim 6 , wherein the middle cabinet further includes a third hook extending from an end of a rear surface of the exposed portion and covering an end of the cover bottom, and

the cover bottom further includes a hook fastener inserted in a front direction at a position corresponding to the third hook.

9 . The display device of claim 1 , wherein the cover bottom includes a flat surface without an unevenness.

10 . The display device of claim 1 , wherein the middle cabinet includes an injection molding, and

the cover bottom and the inner sheet include aluminum.

11 . The display device of claim 1 , further comprising:

a bending module located in a center of a rear surface of the cover bottom;

a pair of links having one end coupled to the bending module and extending left and right; and

link brackets located at left and right ends of the cover bottom and connected to another end of the pair of links,

wherein, when an angle between the pair of links is changed, curvatures of the display module, the inner sheet, and the cover bottom are changed.

12 . The display device of claim 1 , wherein the display module includes an organic light emitting diode panel.

13 . A display device comprising:

a display module configured to output an image;

a drive integrated circuit (IC) located on a rear surface of one end of the display module;

an inner sheet located to form a front gap on the rear surface of the display module;

a cover bottom located to form a rear gap on a rear surface of the inner sheet; and

a middle cabinet covering perimeters of the display module, the inner sheet, and the cover bottom to form a lateral outer appearance,

wherein the inner sheet includes:
