  • Touch control apparatus, control method thereof and electronic device having touch control apparatus
    Patent number: 9658705
    Abstract: A touch control apparatus, a control method thereof and an electronic device having the touch control apparatus are disclosed, which belong to the technical field of touch control. The touch control apparatus comprises: a panel (1); a transmitting antenna (2) arranged on the panel (1) and configured to transmit a detection wave for detecting whether the panel (1) is being touched; at least three resonant circuits arranged on the panel and configured to sense the detection wave and generate resonant waves; and a control processing unit (6) configured to control to process the resonant waves and position information of the resonant circuits to obtain corresponding touch information comprising at least a touch pressure and a touch position. The touch control apparatus, the control method thereof and the electronic device enable touch control of the panel by a general object through utilizing the resonant circuits.
