FIELD: information technology.SUBSTANCE: invention relates to touch input devices. Drive module successively selects one drive line from plurality of touch input device drive lines and applies voltage to selected line of drive, voltage detection module successively selects one sensitive line from plurality of sensitive lines and detects output voltage of selected sensitive line, arithmetic operation module determines value of resistance of sensitive resistive element provided in position, in which selected line and selected sensitive line intersect. At that, drive module apply 0 V or bias voltage equal to or smaller than that of drive, to other drive lines, except for selected line drive.EFFECT: enabling detection of multi point data input with high accuracy.9 cl, 16 dwg |
