    Abstract: A fingerprint identification device includes a plurality of fingerprint sensing electrodes, a shielding enhancement electrode, a fingerprint detection circuit and an auxiliary enhancement signal circuit. The shield enhancement electrode corresponds to a plurality of the fingerprint sensing electrodes. The fingerprint detection circuit is powered by a first power supply and includes a capacitive stimulation signal source. The auxiliary enhancement signal circuit is powered by a second power supply and includes an auxiliary enhancement signal source. The fingerprint detection circuit transmits a capacitive stimulation signal to a selected fingerprint sensing electrode, and receives a fingerprint sensing signal. The fingerprint sensing signal is amplified to generate a capacitive elimination shielding signal. The capacitive elimination shielding signal is transmitted to the shielding enhancement electrode. The auxiliary enhancement signal circuit outputs an auxiliary enhancement signal to the shielding enhancement electrode for performing a fingerprint detection operation.
