1. A touch input device comprising:

  • a first electrode;

    a second electrode located on one side of the first electrode;

    a display disposed on one side of the first electrode opposite to the second electrode; and

    a spacer layer located between the first electrode and the second electrode;

    wherein at least one of the first electrode and the second electrode comprises a plurality of electrodes;

    wherein the first electrode and the second electrode are spaced apart from each other by a predetermined distance;

    wherein one of the first electrode and the second electrode is a drive electrode to which a drive signal is applied;

    wherein the other one of the first electrode and the second electrode is a receiving electrode receives the drive signal by a mutual capacitance between the first electrode and the second electrode;

    wherein when an external pressure is applied to the first electrode through the display, the first electrode is concavely bent toward the second electrode in response to the external pressure;

    wherein the mutual capacitance between the first electrode and the second electrode changes according to a distance between the first electrode and the second electrode; and

    wherein the magnitude of the external pressure according to the change of the capacitance between the first electrode and the second electrode is detected.
