  • Patent number: 10545620
    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.
