  • Touch-type input device
    Patent number: 9691315
    Abstract: A touch-type input device includes a touch panel including drive electrodes and sensor electrodes. Capacitors are formed at intersections of the drive electrodes and sensor electrodes. A controller determines whether a conductive foreign matter exists on the touch panel from raw data values indicating changes in the capacitances of the capacitors from initial reference values. The controller determines touching of the touch panel from control data values indicating changes in the capacitances of the capacitors from control reference values changed when a conductive foreign matter exists. When the raw data values indicate existence of a conductive foreign matter, the controller sets the control reference value of each capacitor to a raw data reference value corresponding to the present raw data value. The controller updates the initial reference value when the touch-type input device is activated and updates the control reference value when the control reference value is erroneous.
