摘要
A touch input device for sensing a touch input in a capacitive manner using a plurality of electrode pads arranged in a matrix structure on a first layer is disclosed. The apparatus comprising: a sensing electrode formed by electrically connecting electrode pads existing in an even-numbered row of a first column among the plurality of electrode pads to electrode pads existing in an odd-numbered row of a second column adjacent to the first column; A driving electrode formed by electrically connecting electrode pads in odd-numbered columns of a first row among the plurality of electrode pads to electrode pads existing in even-numbered rows of a second row adjacent to the first row; An electrode pad potential control unit adapted to apply a driving signal to the driving electrode; And a touch sensing circuit having a charge accumulating capacitor connected to the sensing electrode.
