Abstract

A touch panel includes a protective cover with a lower surface herein, and an active region and a periphery region defined on the lower surface. A first sensing structure is disposed on the lower surface and covers the active region. A shelter layer is disposed on the lower surface and in the periphery region, wherein the>shelter layer includes a highlight region and a highlight contrast region, a first pattern is disposed in the highlight region, and a non-transparent layer with a second pattern is disposed in the highlight region, wherein the first pattern is overlapped by the second pattern.

First claim

What is claimed is:

1 . A touch panel, comprising:
a protective cover having a lower surface, wherein the lower surface comprises an active region and a peripheral region surrounding the active region; a first sensing structure disposed within the active region; a shelter layer disposed within the peripheral region, wherein the shelter layer comprises at least one highlight region and a highlight contrast region; and a non-transparent layer disposed within the highlight region and having a non-hollow portion, wherein the shelter layer comprises a first pattern and a portion not corresponding to the first pattern within each of the highlight regions, and wherein the first pattern is a hollow portion of the shelter layer, and the portion not corresponding to the first pattern is a non-hollow portion of the shelter layer and is overlaid by the non-hollow portion of the non-transparent layer.

2 . The touch panel according to claim 1 , further comprising a second sensing structure disposed between the protective cover and the shelter layer, wherein the second sensing structure is disposed on the shelter layer within the highlight region.

3 . The touch panel according to claim 2 , further comprising a substrate disposed between the shelter layer and the non-transparent layer, wherein the first sensing structure is formed on the substrate.

4 . The touch panel according to claim 1 , further comprising a second sensing structure disposed between the shelter layer and the non-transparent layer, wherein the second sensing structure is disposed corresponding to the highlight region.

5 . The touch panel according to claim 4 , further comprising a substrate disposed under the non-transparent layer, wherein the first sensing structure is formed on the substrate, and the second sensing structure is formed on the non-transparent layer.

6 . The touch panel according to claim 4 , further comprising a substrate disposed between the second sensing structure and the non-transparent layer, wherein the first sensing structure and the second sensing structure are formed on the substrate.

7 . The touch panel according to claim 1 , further comprising a second sensing structure disposed under the non-transparent layer corresponding to the highlight region of the shelter layer.

8 . The touch panel according to claim 7 , further comprising a substrate disposed under the second sensing structure, wherein the first sensing structure and the second sensing structure are formed on the substrate.

9 . The touch panel according to claim 1 , further comprising an adhesive layer disposed between the first sensing structure and the protective cover.

10 . The touch panel according to claim 1 , further comprising a second sensing structure, wherein the first sensing structure and the second sensing structure are located on the same level and are in electrical in contact with each other.

11 . The touch panel according to claim 1 , wherein the first sensing structure comprises:
a first axis electrode; a second axis electrode, wherein the second axis electrode comprises a plurality of conductive units with at least a connection line electrically connecting two adjacent conductive units; and a plurality of conductive lines electrically connected to the first axis electrode and the second axis electrode respectively.

12 . The touch panel according to claim 11 , wherein the connection line and the non-transparent layer comprise a same material.

13 . The touch panel according to claim 11 , wherein the connection line, the non-transparent layer and the conductive lines comprise a same material.

14 . The touch panel according to claim 11 , wherein the conductive lines are disposed within the region where the shelter layer is disposed.

15 . The touch panel according to claim 4 , wherein the non-transparent layer further comprises a third pattern, the second sensing structure comprises a conductive layer having a fourth pattern, wherein the third pattern is overlapped by the fourth pattern.

16 . The touch panel according to claim 1 , wherein the first sensing structure is directly disposed on the lower surface of the protective cover.

17 . The touch panel according to claim 1 , wherein the shelter layer is disposed on the lower surface of the protective layer.

18 . The touch panel according to claim 1 , wherein the non-transparent layer is disposed on the shelter layer.

19 . The touch panel according to claim 1 , wherein the non-transparent layer comprises a second pattern within the highlight region, wherein the second pattern is a hollow portion of the non-transparent layer and is overlapped by the corresponding first pattern.

20 . The touch panel according to claim 19 , wherein the second pattern has the same size as that of the first pattern.

21 . The touch panel according to claim 19 , wherein the second pattern has the same shape as that of the corresponding first pattern, and the non-hollow portion of the non-transparent layer has the same shape as that of the non-hollow portion of the shelter layer within the corresponding highlight region.
