Abstract: The present exemplary embodiments relate to a touch display device and a driving method thereof. According to the present exemplary embodiments, when a touch of the user is sensed during a touch sensing period of each frame, the touch force is sensed by being limited to an area determined based on the sensed touch position, thereby efficiently sensing the touch force. In this case, the touch force sensing is repeated for a limited area during the force sensing period of each frame, so that the touch force sensing report rate is improved. Further, the touch force sensing is performed only during the force sensing period of a frame allocated to a limited area so that power consumption according to the touch force sensing is reduced and the precision for sensing a touch force may be maintained.

Abstract: Embodiments of the disclosure relate to touch display devices. A shielding pattern to which a constant voltage is applied is placed between the touch routing line and the encapsulation part without overlapping the touch routing line. Thus, it is possible to block the noise due to the signal line positioned under the encapsulation part by the electric field generated by the shielding pattern. Further, the metal disposed on the same layer as the shielding pattern in the planarized area of the encapsulation part may be used as a touch routing line, reducing the resistance and width of the touch routing line and hence the planarized area of the encapsulation part. Thus, it is possible to provide a touch display device for which an increase in the non-active area has been reduced and display noise has been reduced upon touch sensing.

Abstract: A driving circuit, a touch display device, and a method of driving the touch display device. A plurality of first electrodes are disposed within a display panel. A second electrode is disposed outside of the display panel. A driving circuit detects at least one of a touch position and a touching force of a touch by sequentially applying a first electrode driving signal to at least one first electrode among the plurality of first electrodes and applying a second electrode driving signal 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.
