1. A touch panel, comprising:

  • a touch layer, for sensing a specific position touched by a finger; and

    a fingerprint sensing layer, disposed under the touch layer, the fingerprint sensing layer comprising;

    a storage unit, for storing a first fingerprint data corresponding to the finger;

    a plurality of receiving modules;

    a plurality of transmission modules, each of the receiving modules being respectively and correspondingly disposed with one of the transmission modules, one of the transmission modules transmitting out a signal according to the specific position, the signal being reflected to the corresponding receiving module by the finger; and

    a control module, for converting the signal received by the receiving module into a second fingerprint data, and for recognizing whether the second fingerprint data matches the first fingerprint data;

    wherein the receiving modules and the transmission modules can be rotatably disposed on a circumference of the fingerprint sensing layer.
