Abstract

A driving circuit (120), a touch display device (100), and a method of driving the touch display device (100). A plurality of first electrodes (El) are disposed within a display panel (110). A second electrode is disposed outside of the display panel (110). A driving circuit (120) detects at least one of a touch position and a touching force of a touch by sequentially applying a first electrode driving signal (DS1) to at least one first electrode among the plurality of first electrodes (El) and applying a second electrode driving signal (DS2) to the second electrode in a touch driving period. When a user touches a screen, not only can a touch position be sensed, but also a touching force with which the user presses the screen can also be efficiently sensed. This provides a range of functions that existing touch position-detecting technologies have failed to provide.
