Change, saved for driving the electric energy touching pumping signal；Ensure that in very first time t1, touch pumping signal and electricity is touched
Feel that the impact of pumping signal is negligible, be simultaneously achieved capacitance electrode 21 and user touch formed between position sufficiently large
Electric potential difference, to ensure that electric touch is perceived by the user.
Certainly, in other implementations, according to different user's requests, touch pumping signal and believe with electro-tactile stimulation
Number amplitude can regulate, such as the user for different age group, due to the difference of tactility, electric touch is fed back
The intensity required is the most variant, can be realized by the amplitude of regulation electro-tactile stimulation signal, and these parameters, at electronic equipment
In can be preferred with personal settings.

More influence factor, such as the factor such as ambient temperature and humidity.
Referring to Fig. 1, in some embodiments, capacitance plate controller 11 is come by the temporal information analyzing fundamental signal
Determine the region of the second time t2.
So, capacitance plate controller 11 is after the temporal information analyzing fundamental signal so that capacitance plate controller 11 is in inspection
When surveying the signal of telecommunication of capacitance electrode 21, it is possible to be accurately positioned the region of the second time t2 on tertiary voltage signal.
Certainly, in other implementations, capacitance plate controller 11 is before the signal of telecommunication of detection capacitance electrode 21, it is possible to
The region of the second time t2 it is accurately positioned with the temporal information by analyzing tertiary voltage signal.
Refer to Fig. 7 a, Fig. 7 b, same touch pumping signal be loaded into different electro-tactile stimulation signals and obtain
Different tertiary voltage signals.
Referring again to Fig. 2, in some embodiments, cover sheet 22 also includes transparent insulating substrate 23 and electric touch
