Abstract

An exemplary embodiment of the present disclosure provides a touch screen structure used in a touch panel. The touch screen structure comprises a protection cover and at least one color changeable decoration layer. The color changeable decoration layer is made of thermochromic material or photochromic material, located at a side region of the lower surface of the protection cover, and the region at which the color changeable decoration layer is located defines a non-visible region of the touch panel.

First claim

What is claimed is:

1. A touch panel defined to have a visible region and a non-visible region, comprising:
a protection cover located in the visible region and the non-visible region of the touch panel;
at least one color changeable decoration layer, made of thermochromic material, located at a side region of a lower surface of the protection cover, wherein a region on which the color changeable decoration layer is located defines the non-visible region of the touch panel;
an insulation layer, located at the lower surface of the protection cover and a lower surface of the color changeable decoration layer; and
a touch substrate, located at a lower surface of the insulation layer, wherein the touch substrate and the protection cover are in direct contact with the insulation layer.

2. The touch panel according to claim 1 , wherein the thermochromic material is heat sensitive material.

3. The touch panel according to claim 1 , wherein the thermochromic material comprises liquid crystals packaged by microscopic capsules.

4. The touch panel according to claim 1 , wherein the insulation layer is a transparent optical adhesive.

5. The touch panel according to claim 1 , wherein the touch substrate comprises a sensing electrode.

6. A touch panel defined to have a visible region and a non-visible region, comprising:
a protection cover located in the visible region and the non-visible region of the touch panel;
at least one color changeable decoration layer, made of photochromic material, located at a side region of a lower surface of the protection cover, wherein a region on which the color changeable decoration layer is located defines the non-visible region of the touch panel;
an insulation layer, located at the lower surface of the protection cover and a lower surface of the color changeable decoration layer; and
a touch substrate, located at a lower surface of the insulation layer, wherein the touch substrate and the protection cover are in direct contact with the insulation layer.

7. The touch panel according to claim 6 , wherein the photochromic material is metamerism.

8. The touch panel according to claim 6 , wherein the photochromic material comprises spiro indoline, spiro pyran, spiro oxazine, or combination thereof.

9. The touch panel according to claim 6 , wherein the insulation layer is a transparent optical adhesive.

10. The touch panel according to claim 6 , wherein the touch substrate comprises a sensing electrode.

11. A touch panel defined to have a visible region and a non-visible region, comprising:
a protection cover located in the visible region and the non-visible region of the touch panel;
at least one color changeable decoration layer, made of thermochromic material, located at a side region of a lower surface of the protection cover, wherein a region on which the color changeable decoration layer is located defines the non-visible region of the touch panel; and
a touch sensing electrode layer, formed under the protection cover and the color changeable decoration layer.

12. The touch panel according to claim 11 , wherein the thermochromic material is heat sensitive material.

13. The touch panel according to claim 11 , wherein the thermochromic material comprises liquid crystals packaged by microscopic capsules.

14. The touch panel according to claim 11 , wherein the touch sensing electrode layer is directly formed under the lower surface of the protection cover and a lower surface of the color changeable decoration layer.

15. The touch panel according to claim 11 , further comprising a smoothing layer, wherein the smoothing layer is located at the lower surface of the protection cover and located at a visible region corresponding to the non-visible region of the touch panel, wherein the touch sensing electrode layer is formed at the lower surface of the smoothing layer.

16. The touch panel according to claim 15 , wherein the smoothing layer is made of polymer.

17. A touch panel defined to have a visible region and a non-visible region, comprising:
a protection cover located in the visible region and the non-visible region of the touch panel;
at least one color changeable decoration layer, made of photochromic material, located at a side region of a lower surface of the protection cover, wherein a region on which the color changeable decoration layer is located defines the non-visible region of the touch panel; and
a touch sensing electrode layer, formed under the protection cover and the color changeable decoration layer.

18. The touch panel according to claim 17 , wherein the photochromic material is metamerism.

19. The touch panel according to claim 17 , wherein the photochromic material comprises spiro indoline, spiro pyran, spiro oxazine, or combination thereof.

20. The touch panel according to claim 17 , wherein the touch sensing electrode layer is directly formed under the lower surface of the protection cover and a lower surface of the color changeable decoration layer.

21. The touch panel according to claim 17 , further comprising a smoothing layer, wherein the smoothing layer is located at the lower surface of the protection cover and located at a visible region corresponding to the non-visible region of the touch panel, wherein the touch sensing electrode layer is formed at a lower surface of the smoothing layer.

22. The touch panel according to claim 21 , wherein the smoothing layer is made of polymer.
