Abstract
A touch control device capable of preventing false positives is provided. The touch control device includes: a conductive plate, electrically connected to a predetermined potential; a sensing region, located above the conductive plate, including a plurality of capacitive sensing units; and a conductive ring, located above the conductive plate, disposed at a periphery of the sensing region. When a touch scanning signal is provided to one on-duty capacitive touch sensing unit of the capacitive touch sensing units, the conductive ring synchronously receives a control signal associated with the touch scanning signal.
