ABSTRACT:
The invention discloses a touch panel capable of identifying fingerprints. The touch panel includes a touch layer and a fingerprint sensing layer. The touch layer is used for sensing a specific location touched by a finger. The fingerprint sensing layer is disposed under the touch layer and includes a storage unit, multiple receiving modules, multiple transmitting modules, and a control module. The storage unit stores a first fingerprint data corresponding to the finger. Each receiving module respectively corresponds to one of the transmission modules. According to the specific location, one of the transmission modules transmits a signal, and the signal is then reflected by the finger to the corresponding receiving module. The control module converts the signal received by the receiving module into a second fingerprint data and then determines whether the second fingerprint data conforms to the first fingerprint data.
