Claim Text:
1. A touch device having a touch area and a surrounding area, comprising: a sensing electrode structure formed on the touch area; a shielding layer formed on the surrounding area, wherein the shielding layer surrounds the sensing electrode structure; a first insulation element formed on the surrounding area, wherein the first insulation element is only formed along two adjacent sides of the touch area so that the first insulation element is geometrically shaped in a manner that partially covers the shielding layer; a plurality of peripheral connection wires formed on the surrounding area and corresponding to the first insulation element, wherein the first insulation element is formed between the peripheral connection wires and the shielding layer, and the peripheral connection wires are electrically insulated from the shielding layer and are electrically connected to the sensing electrode structure; and a grounding wire formed on the surrounding area and electrically connected to the shielding layer; wherein the touch area has a plurality of sides, the shielding layer surrounds all of the sides of the touch area, the first insulation element is formed continuously along the two adjacent sides of the sides of the touch area so that the first insulation element partially covers the shielding layer, the peripheral connection wires are substantially formed on the first insulation element in a manner such that the peripheral connection wires are only formed along the two adjacent sides of the sides of the touch area, and the grounding wire surrounds a periphery of the peripheral connection wires.
