Abstract:
The present embodiments relate to a touch technology and, more particularly, to a touch display device, which includes multiple first electrodes embedded in a display panel, at least one second electrode positioned outside the display panel, and a touch force sensing gap existing between the multiple first electrodes and the at least one second electrode, a method for driving the same, and a driving circuit for driving the multiple first electrodes and the at least one second electrode. The present embodiments, as described above, make it possible to sense not only a touch position, but also a touch force, with which the user presses the screen during a touch.
