Abstract

A display device is provided. The display device includes a screen display unit, a first nontransparent layer, and a second nontransparent layer. The screen display unit includes a first screen region and a second screen region of which at least a portion is curved from the first screen region. The first nontransparent layer is disposed in at least one side of border portions of the screen display unit. The second nontransparent layer is disposed in at least one side of border portions of the second screen region and is separated from at least a portion of the first nontransparent layer in a direction perpendicular to the first nontransparent layer.

Claims

1. A display device comprising:

a screen display unit including a first screen region and a second screen region of which at least a portion is curved from the first screen region;

a first nontransparent layer disposed in at least one side of border portions of the screen display unit; and

a second nontransparent layer disposed in at least one side of border portions of the second screen region and separated from at least a portion of the first nontransparent layer in a direction perpendicular to the first nontransparent layer.

2. The display device of claim 1, wherein the screen display unit includes a screen region in which an image is displayed and a non-screen region in which the image is not displayed,

wherein the first nontransparent layer or the second nontransparent layer is disposed in the non-screen region.

3. The display device of claim 1, wherein the display device comprises:

a display panel;

a touch panel disposed on the display panel, wherein the touch panel includes a signal pattern disposed in the screen display unit and a connection line of the signal pattern, the connection line being disposed in the screen display unit; and

a window cover disposed on the touch panel,

wherein the first nontransparent layer is disposed on at least one surface of the window cover.

4. The display device of claim 3, wherein the second nontransparent layer is disposed on at least one surface of a reinforcing member disposed between the touch panel and the window cover.

5. The display device of claim 4, wherein the second nontransparent layer is disposed to cover at least a portion of the connection line.

6. The display device of claim 3, wherein the second nontransparent layer is disposed on a side of the touch panel.

7. The display device of claim 3, wherein the second nontransparent layer is disposed to block visible light reflecting from the connection line.

8. The display device of claim 1, wherein the first nontransparent layer or the second nontransparent layer is formed in at least one of a pattern or a non-pattern having at least one shape of a hair line, a stitch, a mesh, an embossing, and a punching.

9. The display device of claim 1, wherein the first nontransparent layer or the second nontransparent layer is formed by at least one of being printed, painted, and deposited.

10. The display device of claim 1, wherein the first nontransparent layer or the second nontransparent layer is formed of at least one material of ink, film, and tape.

11. The display device of claim 3, wherein the display device further comprises a digitizer panel determining at least one input and a conductive sheet member attaching to a bottom portion of the digitizer panel,

wherein the conductive sheet member includes a first conductive sheet member corresponding to the first screen region and a second conductive sheet member corresponding to the second screen region, and

wherein a portion of the first conductive sheet member is formed of a first material, and a portion of the second conductive sheet member is formed of a second material.

12. The display device of claim 11, wherein the first conductive sheet member contacts the second conductive sheet member in a border of the first screen region and the second screen region.

13. The display device of claim 3, wherein the display device comprises a digitizer panel determining at least one input and a conductive sheet member attaching to a bottom portion of the digitizer panel,

wherein the conductive sheet member includes at least one slit unit in a region corresponding to the second screen region.

14. The display device of claim 3, wherein the display device further comprises a digitizer panel determining at least one input, a conductive sheet member attaching to a bottom portion of the digitizer panel, and a coupling member disposed between the digitizer panel and conductive sheet member to couple the digitizer panel and conductive sheet member with each other,

wherein the coupling member comprises a first coupling member corresponding to the first screen region and a second coupling member corresponding to the second screen region, and

wherein a portion of the first coupling member is formed of a first material, and a portion of the second coupling member is formed of a second material.

15. The display device of claim 14, wherein an adhesive strength of the second material is greater than an adhesive strength of the first material.

16. The display device of claim 3, wherein the display device further comprises a digitizer panel determining at least one input and a conductive sheet member attaching to a bottom portion of the digitizer panel,

wherein at least a portion of the digitizer panel is curved to correspond to the second screen region.

17. The display device of claim 16, wherein at least a portion of the display device is laminated to be coupled, and different pressure or temperature values are applied to the first screen region and the second screen region from each other during lamination.

18. The display device of claim 17, wherein a pressure value applied to the first screen region is greater than a pressure value applied to the second screen region, and a temperature value applied to the second screen region is greater than a pressure value applied to the first screen region.

19. The display device of claim 3, wherein at least one of sealing member is attached to a side of the display panel, a side of the touch panel, and a side of the window cover.

20. The display device of claim 19, wherein the display device further includes a display bracket supporting the display panel, wherein the display bracket includes at least one offset unit.

21. A display device comprising:

a screen display unit including a first screen region and a second screen region of which at least a portion is curved from the first screen region; and

a detachment limit module preventing a detachment between a plurality of layers or panels in the display device,

wherein the detachment limit module is implemented in different manners from each other in a first detachment limit region corresponding to the first screen region and a second detachment limit region corresponding to the second screen region.

22. The display device of claim 21, wherein at least a portion of a first material included in the detachment limit module of the first detachment limit region is different from at least a portion of a second material included in the detachment limit module of the second detachment limit region.

23. The display device of claim 22, wherein an adhesive strength of the first material is different from an adhesive strength of the second material.
