  • Patent number: 10564758
    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.
