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 hovering and touch sensing apparatus with auxiliary capacitance-exciting signal includes a plurality of touch sensing electrodes, a system circuit and a touch control circuit. When an operating object approaches or touches the touch sensing electrodes for hovering or touch sensing, there is no common circuit loop between the system circuit and the touch-sensing circuit to prevent the influence of the system circuit to the touch control circuit. The touch control circuit sends a capacitance-exciting signal to the operating object through a first specific conductor. The touch control circuit sends an auxiliary capacitance-exciting signal to a selected touch-sensing electrode and a touch-sensing circuit receives a touch sensing signal from the selected touch-sensing electrode.

Abstract: A rapid identification method for fingerprint first provides a fingerprint identification apparatus having a fingerprint sensing area and divides the fingerprint sensing area into fingerprint sensing sub-regions. In a registration stage, the method performs fingerprint sensing for the entire fingerprint sensing area to obtain fingerprint image for a whole fingerprint sensing area, fingerprint minutiae and relevant locations for the fingerprint minutiae and then pre-stores those data. In an identification stage, the method performs fingerprint sensing on a part of the fingerprint sensing sub-regions for a user to be identified and detects fingerprint minutiae and relevant locations for the fingerprint minutiae in the part of the fingerprint sensing sub-regions. The method compares the fingerprint minutiae and relevant locations detected in the identification stage with respect to the corresponding fingerprint minutiae and relevant locations in the registration stage in order to determine whether the user can be granted with access right.
