Abstract: A touch input device may be provided that includes: a touch sensor panel comprising n number of drive electrodes, m number of receiving electrodes, and a plurality of node capacitors which are formed by the drive electrodes and the receiving electrodes; a driving part which applies a driving signal to the drive electrode; a data processor which receives a signal including information on a capacitance of the node capacitor through the receiving electrode and detects touch information on the touch sensor panel; and a controller which controls the driving part to apply the driving signal to k number of the drive electrodes of n number of the drive electrodes in a first drive mode. The “n”, “m”, and “k” are natural numbers greater than 2 and “k” is less than “n”.
