1. A touchscreen, comprising:

  • a first substrate having a first surface;

    a second substrate having a second surface facing the first surface;

    an insulating layer disposed between the first substrate and the second substrate;

    a plurality of first sensing patterns disposed between the first substrate and the insulating layer;

    a plurality of conductive wires disposed between the first substrate and the insulating layer;

    a plurality of second sensing patterns disposed between the second substrate and the insulating layer;

    a conductive component electrically connecting the second sensing patterns and the conductive wires; and

    a printed circuit board electrically connecting the conductive wires and having conductive traces laid only on its one surface;

    wherein the second surface of the second substrate is free of conductive wires; and

    wherein the conductive wires comprise a first portion and a second portion, the first sensing patterns connect with the first portion, and the second sensing patterns connect with the second portion via the conductive component; and

    wherein the first sensing patterns and the second sensing patterns are used for generating a plurality of touch signals, and the touch signals are transmitted to the printed circuit board via the conductive wires.
