摘要： A group-verification fingerprint identifying method includes: simultaneously receiving fingerprint input operations from multiple users via a multi-finger fingerprint sensor of a fingerprint identifying apparatus for multiple fingers; generating a fingerprint combination corresponding to the fingerprint input operations; retrieving a registered fingerprints combination; generating a comparison result via comparing the fingerprints combination with the registered fingerprint combination. A more complicated verification mechanism can be provided to enhance security of identification via using group-verification and fingerprint identification.

摘要： A high-sensitivity in-cell touch display device has a common voltage and sensing electrode layer including a plurality of common voltage and sensing electrodes, each corresponding to at least one pixel electrode. A touch circuit is provided with a touch-dedicated power supply circuit, and a common voltage and sensing electrode is used as a common node of the touch circuit and a display circuit, so that there is no current loop between the touch circuit and the display circuit. Reflection electrodes are further provided to reduce parasitic capacitance between the common voltage and sensing electrodes and to improve the sensing distance. The display operation and the touch sensing operation can be performed on different areas in parallel to increase respective efficiencies of the display and touch sensing operations.

摘要： 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.

摘要： 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.
