Abstract
A touch driving circuit includes: a first sensing driver including a first sensing capacitor connected to a first touch electrode; a second sensing driver including a second sensing capacitor connected to a second touch electrode; and a touch sensing unit connected to the first and second sensing drivers to sense a voltage charged in each of the first and second sensing capacitors. A charging time point of the first sensing capacitor is different from a charging time point of the second sensing capacitor, and a discharging time point of the first sensing capacitor is different from a discharging time point of the second sensing capacitor.
