Abstract: A hovering and touch sensing apparatus includes a plurality of touch sensing electrodes, a system circuit and a touch control circuit. When an operating object approaches to or touches the touch sensing electrodes for hovering or touch sensing operation, there is no common circuit loop between the system circuit and the touch control circuit to prevent the influence of the system circuit to the touch-sensing circuit. Besides, the touch control circuit sends a capacitance-exciting signal to the operating object through a first specific conductor of the system circuit, thus more effectively send the capacitance-exciting signal to the operating object and enhance the preciseness for sensing the touch sensing signal.
