Abstract
A fingerprint sensing device comprises a shielding plate configured between an electrode plate and a detection circuit for reducing a parasitic capacitor between the electrode plate and a conductor thereunder. Consequently, a larger signal dynamic range can be achieved and the electrode plate can be prevented from operation noise interference of the detection circuit. The shielding plate and the electrode plate have the same potential. Accordingly, a parasitic capacitor effect between the shielding plate and the electrode plate can be eliminated. Thus, the fingerprint sensing device of the present invention has a better noise resistibility.
