Touch panel

摘要

A touch panel includes a substrate, a shielding layer, a first electrode layer, a first insulation layer, a second electrode layer, a lead layer and a second insulation layer. The substrate has a touch section and a non-touch section. The shield layer and the lead layer are disposed on the non-touch section. The first and second electrode layers are disposed on touch section. The first insulation layer is disposed between the first and second electrode layers corresponding to the second electrode layer. The second insulation layer is overlaid on the second electrode layer and the lead layer. In the touch panel, the number of leads is reduced. Moreover, the touch panel is free from the problems of interference and signal interference between the electrodes.

1. A touch panel comprising:
a substrate having a touch section and a non-touch section positioned on a periphery of the touch section; a shield layer disposed on the non-touch section and covering one side of the substrate; a first electrode layer disposed on touch section to partially extend to the non-touch section and covering one side of the shield layer, which side is distal from the substrate; a first insulation layer overlaid on one side of the first electrode layer, which side is distal from the substrate to completely cover the part of the first electrode layer disposed on the touch section, the first insulation layer also partially covering the part of the first electrode layer disposed on the non-touch section; a second electrode layer disposed on the other side of the first insulation layer, which side is distal from the first electrode layer corresponding to the touch section, the second electrode layer partially extending to the non-touch section; a lead layer disposed on the non-touch section corresponding to the shield layer and having a first lead and a second lead, the first lead covering one side of the first electrode layer, which side is distal from the first insulation layer to electrically connect to the first electrode layer, while the second lead covers the second electrode layer and the first insulation layer to electrically connect to the second electrode layer; and a second insulation layer overlaid on the second electrode layer and the lead layer.
