Touch input sensing method and apparatus for reducing parasitic capacitance effects

摘要

Disclosed is a touch input sensing device comprising: a touch input sensing electrode; a touch sensing unit connected to one point of the touch input sensing electrode to measure a change in a touch capacitance formed by the touch input sensing electrode according to a touch input; a second node included in the touch input sensing device to form a capacitance between the one point and the second node; and a potential control unit for providing a potential value following the potential of the one point to the second node to decrease a potential difference between the one point and the second node.
