Abstract: A fingerprint sensing apparatus includes a plurality of fingerprint sensing electrodes, a plurality of data lines respectively sandwiched by a first capacitance-shielding wire and a second capacitance-shielding wire, a fingerprint sensing circuit including a driver circuit with a gain larger than zero or equal to zero. During fingerprint sensing, the fingerprint sensing circuit sends a capacitance-exciting signal to a selected fingerprint sensing electrode, receiving a fingerprint sensing signal from the selected fingerprint sensing electrode, processing the fingerprint sensing signal with the driver circuit into a capacitance-eliminating signal and applying the capacitance-eliminating signal to the first capacitance-shielding wire and the second capacitance-shielding wire respectively. The capacitance between the first/second capacitance-shielding wire and the corresponding data line can be greatly reduced because the voltages at the first/second capacitance-shielding wire have same phase as that of corresponding data line, thus greatly enhance the accuracy of the fingerprint sensing apparatus.

Abstract: A fingerprint identification apparatus having a conductive structure includes an insulated casing, a conductive wire, and a fingerprint identification module. The insulated casing has a first surface with a fingerprint detection region and a second surface. The conductive wire has a first wire segment and a second wire segment. The first wire segment forms on the first surface and contacts with the fingerprint detection region. The second wire segment forms on the second surface and electrically connects to the first wire segment. The fingerprint identification module is disposed on the second surface and electrically connected to the second wire segment. Therefore, the conductive structure for fingerprint identification is provided to increase accuracy and security of the fingerprint identification and reduce manufacturing costs.
