Abstract
A touch device is provided. The touch device, having a sensing area and a peripheral area, includes a touch-sensing layer, a shielding layer disposed at the peripheral area of and separated from the touch-sensing layer, and an insulating layer disposed between the touch-sensing layer and the shielding layer. Moreover, a fabrication method of a touch device is provided.
Claims29
A touch device, having a sensing area and a peripheral area surrounding the sensing area, comprising:
- a touch-sensing layer;
- a shielding layer disposed at the peripheral area and separated from the touch-sensing layer;
- and
- an insulating layer disposed between the touch-sensing layer and the shielding layer.
A touch device, having a sensing area and a peripheral area surrounding the sensing area, comprising:
- a substrate:
- a sensing electrode disposed on the substrate and at the sensing area;
- a mask layer disposed on the substrate and at the peripheral area;
- a signal conveying trace electrically connecting to the sensing electrode and covered by the mask layer;
- an induced layer disposed on the mask layer;
- an insulating layer disposed between the induced layer and the signal conveying trace and between the induced layer and the sensing electrode;
- and
- a conductive layer disposed on the induced layer and electrically connected with the induced layer.
A method for fabricating a touch device, wherein the touch device has a sensing area and a peripheral area surrounding the sensing area, comprising:
- forming a touch-sensing layer;
- forming a shielding layer at the peripheral area, wherein the shielding layer is separated from the touch-sensing layer;
- and
- forming an insulating layer between the touch-sensing layer and the shielding layer.
