In step S33, according to magnitude of voltage, voltage rising time is obtained.
In the present embodiment, after touch control operation corresponding magnitude of voltage is collected, you can know the first of contact panel
The voltage of touch control electrode layer rises to the time of predeterminated voltage from reference voltage.Wherein, touch-control pressure is different, on corresponding voltage
The time of liter is also different, and such as touch-control pressure is bigger, and corresponding voltage rising time is shorter, and touch-control pressure is smaller, on corresponding voltage
The time of liter is longer.
In step S34, according to the mapping relations between default voltage rising time and touch-control pressure, it is determined that and voltage
Rise time corresponding touch-control pressure.
In step s 35, corresponding control operation is performed according to the touch-control pressure of determination.
