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 touch control method is provided. The method includes: providing a touch device with multiple touch electrodes; determining whether an object is located in a sensing distance; detecting a sensing group sensing the object if the determination is yes; determining whether an electrode amount in the electrode group is between a first value and a second value; determining whether a sensing time of a predetermined proportion of the touch electrodes in the sensing group is equal to or greater than a predetermined time; executing a fingerprint recognition mode if the electrode amount is between the first value and the second value, and the sensing time is equal to or greater than the predetermined time; executing a touch operation mode if the electrode amount is less than the first value or greater than the second value, or the sensing time is less than the predetermined time.

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.
