1. A touch panel, comprising:

  • a first substrate;

    a sensing electrode structure disposed on the first substrate for producing a first capacitance between the sensing electrode structure and an exterior object;

    a second substrate parallel to the first substrate;

    a soft spacer layer interposed between the first substrate and the second substrate for maintaining a gap between the first substrate and the second substrate; and

    a shielding layer disposed on the second substrate, electrically connected to a ground side, and used for producing a second capacitance between the shielding layer and the sensing electrode structure when the exterior object is pressed and causes the gap to vary, wherein the quantity of variation in the first and second capacitances is used for detecting a touch-control action of the exterior object, wherein the shielding layer is made from a transparent conductive material.
