TOUCH INPUT SENSING METHOD USING MUTUAL CAPACITANCE WITH MATRIX-DISPOSED ELECTRODE PADS AND DEVICE FOR THE SAME

摘要

Disclosed is a touch input device to sense a touch input with a mutual capacitance method by using a plurality of electrode pads arranged on a first layer as a matrix structure. The device comprises: a sensing electrode formed by electrically connecting electrode pads in an even-numbered row of a first column and electrode pads in an odd-numbered row of a second column adjacent to the first column among the electrode pads; a driving electrode formed by electrically connecting electrode pads in an odd-numbered column of a first row and an even-numbered column of a second row adjacent to the first row among the electrode pads; an electrode pad potential control unit to apply a driving signal to the driving electrode; and a touch sensing circuit wherein a capacitor for charge accumulation is connected to the sensing electrode.
