Quantity depending on, but the present embodiment is not especially limited the quantity of sub-electrode.
Based on this, due under humidity of skin detection pattern terminal to be located at predeterminable area multiple sub-electrodes be applied with phase
With voltage signal, therefore multiple sub-electrode can the equivalent formation biggish detecting electrode of one area, this is equivalent to expand
The electrode area of humidity of skin detection, so that the position for being not easy to carry out humidity of skin detection originally is also able to achieve detection, simultaneously
Also improve the load capacity of capacitor.
Based on above-mentioned embodiment, in the difference for determining collected capacitance signal and reference capacitance signal beyond threshold value
Later, before and the capacitance signal being determined as target capacitance signal, which can also be filtered, it will
