Being intended to, this method monitoring touch on the touchscreen can be applied has the terminal unit (example of touch screen
As: smart mobile phone, panel computer) on, wherein, touch screen is provided with suspension electrode, suspension electrode
It is arranged between the surface cap of touch screen and the touch control electrode of touch screen, as shown in Figure 1A, should touch
Touch the method that the upper monitoring of screen touches and comprise the following steps S101-S 102:
In step S101, determine that the electric capacity of the self-capacitance capacitance between suspension electrode and touch control electrode becomes
Whether change amount reaches the excursion of self-capacitance capacitance corresponding to steady statue.
In one embodiment, the touch behavior on touch screen can be added up, determine different hardware class
The touch screen of type touch screen when pressing is in the excursion of self-capacitance capacitance corresponding to steady statue.?
In one embodiment, as shown in Figure 1A, suspension electrode 111 place on finger touch intelligent mobile phone 10
Surface cap 11 is one and gradually changes until stable process, and in this process, human finger skin exists
During contact touch screen there is following change in skin texture: finger initially touches suspension electrode 111
The surface cap 11 at place for epiderm skin, hair, fingernail etc.;Touch along with finger continues face contact
The process touching screen continues, and the skin lines of finger can launch at the contact plane of surface cap 11, skin antiperspirant
Perspiration in glandular orifice can overflow, the coupling conducting and can further enhance of finger and suspension electrode.
In step s 102, if it is determined that capacitance change reaches the excursion of self-capacitance capacitance, really
