Abstract

A touch device according to the embodiment includes a display panel; and a touch panel disposed on the display panel and including a curved surface, wherein an air gap is formed between the display panel and the touch panel. Thus, erosion and defects of components caused by the moisture penetrating into the air gap can be prevented so that the touch device according to the embodiments can improve the durability and the reliability.

First claim

1 . A touch device comprising:
a cover case; a display panel on the cover case; and a touch panel disposed on the display panel and including a curved surface, wherein an air gap is formed between the display panel and the touch panel.

2 . The touch device of claim 1 , wherein the touch panel comprises at least one of a concave surface and a convex surface.

3 . The touch device of claim 2 , further comprising a reinforcing member disposed in the air gap.

4 . The touch device of claim 3 , wherein the reinforcing member is transparent.

5 . The touch device of claim 3 , wherein the reinforcing member comprises at least one of an air layer, an adhesive layer and a plastic layer.

6 . The touch device of claim 1 , wherein the touch panel has a radius of curvature in a range of 300 mm to 1000 mm.

7 . The touch device of claim 1 , wherein the touch panel comprises a cover substrate, a sensing electrode on the cover substrate and a wire electrode on the cover substrate, and at least one of the sensing electrode and the wire electrode is arranged in a formed of a mesh.

8 . A touch device comprising:
a cover case; a display panel disposed on the cover case and including a curved surface; and a touch panel disposed on the display panel and including a curved surface, wherein an air gap is formed between the cover case and the touch panel.

9 . The touch device of claim 8 , wherein the display panel and the touch panel comprise at least one of a concave surface and a convex surface.

10 . The touch device of claim 9 , further comprising a reinforcing member disposed in the air gap.

11 . The touch device of claim 10 , wherein the reinforcing member comprises a transparent reinforcing member and the transparent reinforcing member comprises at least one of an air layer, an adhesive layer and a plastic layer.

12 . The touch device of claim 8 , wherein the display panel and the touch panel have a radius of curvature in a range of 300 mm to 1000 mm.

13 . The touch device of claim 8 , wherein a radius of curvature of the display panel is identical to or different from a radius of curvature of the touch panel.

14 . A touch device comprising:
a cover case; a display panel disposed on the cover case and including a curved surface; and a touch panel disposed on the display panel and including a curved surface, wherein a first air gap is formed between the cover case and the display panel and a second air gap is formed between the display panel and the touch panel.

15 . The touch device of claim 14 , wherein the display panel and the touch panel comprise at least one of a concave surface and a convex surface, and the curved surface of the display panel has directionality different from directionality of the curved surface of the touch panel.

16 . The touch device of claim 15 , further comprising a first reinforcing member disposed in the first air gap and a second reinforcing member disposed in the second air gap.

17 . The touch device of claim 16 , wherein the first and second reinforcing members comprise transparent reinforcing members and the transparent reinforcing members comprise at least one of an air layer, an adhesive layer and a plastic layer.

18 . The touch device of claim 17 , wherein the first and second reinforcing members include same material or mutually different materials.

19 . The touch device of claim 18 , wherein a radius of curvature of the display panel is identical to or different from a radius of curvature of the touch panel.

20 . The touch device of claim 14 , wherein the touch panel comprises a cover substrate, a sensing electrode on the cover substrate and a wire electrode on the cover substrate, and at least one of the sensing electrode and the wire electrode is arranged in a form of a mesh.
