Disclosed are a driving circuit, a touch display device, and a method of driving the same. The touch display device for sensing a user's touch force may sense a capacitance change due to a change in a contact area on a display panel after a section in which a sensing value of a touch force based on a change in capacitance between first electrodes and a second electrode becomes a saturated state, thereby sensing the user's touch force even in a section where the change in the capacitance between the first electrodes and the second electrode is small. Accordingly, it is possible to expand a range in which a user's touch force can be sensed and acquire data on a user's touch force linearly indicated in the expanded range, so that touch force leveling becomes easy and various inputs based on the touch force can be processed.
