Abstract: A touch input device preventing a flicker from occurring on a display screen caused by multi-driving of a touch sensor. The touch input device includes a display panel having a plurality of scan lines; a touch sensor including a plurality of driving electrodes arranged in the same direction as the scan line and a plurality of receiving electrodes arranged in a direction different from the scan line; and a control unit configured to perform a touch scan so that driving signals are applied to two or more driving electrodes of the plurality of driving electrodes. The control unit controls a driving timing of the touch scan so that the scan line to which a display scan signal is applied of the plurality of scan lines and the driving electrodes to which the driving signals are applied are not in overlap with each other in terms of time and space.
