Touch input sensing method for reducing effects of stray capacitances and device for the same

摘要

A touch input sensing device comprising: a touch input sensing electrode; A touch sensing unit connected to a point of the touch input sensing electrode and adapted 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, wherein a capacitance is formed between the first node and the one point; And a potential control unit for providing the second node with a potential value following the potential of the one point so as to reduce the potential difference between the one point and the second node.
