Abstract:
A touch sensing module includes: a first sensing coil and a second sensing coil, each having inductance varying in response to an applied force touch; a first pad having capacitance varying in response to an applied contact touch, disposed closer to the second sensing coil than to the first sensing coil, and electrically connected to the first sensing coil to constitute a first resonance circuit; and a second pad having capacitance varying in response to the applied contact touch, disposed closer to the first sensing coil than to the second sensing coil, and electrically connected to the second sensing coil to constitute a second resonance circuit.
