Abstract
A touch and proximity sensing device includes a circuit board and a sensed signal processing unit including only one sensed signal conversion engine. The circuit board includes a capacitor sensing electrode and a grounding conductor foil disposed on opposite surfaces of the circuit board, and has a proximity sensing electrode formed thereon. The grounding conductor foil is spaced apart from the proximity sensing electrode in a planar direction parallel to the surfaces of the circuit board. The sensed signal conversion engine is spaced apart from the capacitor sensing electrode and the proximity sensing electrode in the planar direction and detects electric sensed signals from the capacitor sensing electrode and the proximity sensing electrode.
