Abstract:
A touch device with fingerprint identification function includes a glass substrate having a first and a second face, a first electrode layer having multiple first electrodes, an insulation layer, a second electrode layer having multiple second electrodes, a wiring layer, a film layer covering the second electrode layer and the wiring layer, and a fingerprint identification sensation layer having multiple fingerprint identification chips and multiple transmission leads. The first face is defined with a touch section and a non-touch section. The first electrode layer is disposed on the second face. One face of the insulation layer covers the first electrode layer. The second electrode layer is disposed on the other face of the insulation layer. The wiring layer is disposed at the non-touch section and selectively electrically connected to the first and second electrode layers. The touch device is able to lower manufacturing cost and enhance fingerprint identification precision.
