Abstract:
The present invention provides a touch driving device comprising: a driving channel for supplying a first driving voltage to a sensor electrode in a multi-touch mode and supplying a second driving voltage smaller than the first driving voltage to a sensor electrode group in a one-touch mode; and a connection unit for connecting the sensor electrode to the driving channel in the first mode and connecting the sensor electrode group to the driving channel in the second mode.
