(not shown), power supply is used to produce feedback detection signal.Feedback detection signal is delivered to touch feedback electrode by second circuit 60
On layer 20 and for producing electric touch feedback to human body.
If the control touch-screen 100 of processor 40 provides first and operates, the first circuit 50 of control of processor 40 makes processor
40 are electrically connected by the first circuit 50 and contact conductor 36 with touch control electrode block 34, and processor 40 is also controlled by second circuit 60
Touch feedback electrode layer 20 is grounded, and now touch feedback electrode layer 20 serves as the underlying shield conductive layer of touch control electrode layer 30, is used for
Display module (for example, display screen) and posting that touch control electrode layer 30 (touch control electrode block 34) is formed in shielding electronic installation 200
The influence of raw electric capacity.When existence position detection signal on touch control electrode layer 30 (touch control electrode block 34) and user does not operate touch
When shielding 100, the position detection signal on touch control electrode layer 30 (touch control electrode block 34) keeps constant.When touch control electrode layer 30 (is touched
Control electrode block 34) on existence position detection signal and during user's operation touch-screen 100, human body and (the touch-control electricity of touch control electrode layer 30
Pole block 34) composition touch control capacitance (not shown), and send out the position detection signal on touch control electrode layer 30 (touch control electrode block 34)
Changing, position detection signal makes touch control electrode layer 30 (touch control electrode block 34) and touch control capacitance obtain user behaviour after changing
Make the manipulation position signalling produced during touch-screen 100.In this way, processor 40 is real according to manipulation position signalling control touch-screen 100
Existing suspension procedure.Specifically, a part for the finger of user or human body is located at the first surface 12 of cover plate 10 or positioned at cover plate 10
The side of first surface 12 and when there is certain distance with first surface 12, the finger of user or a part for human body can be with
Touch control electrode layer 30 (touch control electrode block 34) constitutes touch control capacitance, and makes the position on touch control electrode layer 30 (touch control electrode block 34)
Detection signal changes, and then touch control electrode layer 30 (touch control electrode block 34) and touch control capacitance is obtained user's operation touch-screen
The manipulation position signalling produced when 100.
If the control touch-screen 100 of processor 40 provides second and operates, the control second circuit 60 of processor 40 makes processor
40 are electrically connected by second circuit 60 and touch feedback contact conductor 26 with touch feedback electrode 24, and processor 40 also passes through first
The control touch control electrode layer 30 of circuit 50 is grounded.Believe when there is feedback detection on touch feedback electrode layer 20 (touch feedback electrode 24)
Number and user when not having operation touch-screen 100, the feedback detection signal on touch feedback electrode layer 20 (touch feedback electrode 24)
Keep constant.Detection signal and user's operation touch-screen are fed back when existing on touch feedback electrode layer 20 (touch feedback electrode 24)
When 100, human body constitutes touch feedback electric capacity (not shown) with touch feedback electrode layer 20 (touch feedback electrode 24).Now, by
In touch feedback electrode layer 20 (touch feedback electrode 24) and human body be the two poles of the earth of touch feedback electric capacity, therefore the electricity on human body
By the feedback detection signal control on touch feedback electrode layer 20 (touch feedback electrode 24), if feedback detection signal can make
Electric quantity change on human body simultaneously produces concussion electric field, then human body directly obtains electric touch feedback, in this way, touch feedback electrode layer 20
(touch feedback electrode 24) can provide electric touch feedback directly to human body.
The electronic installation 200 and touch-screen 100 of embodiment of the present invention, touch feedback is set by touch-screen 100
Electrode layer 20 simultaneously enables touch-screen 100 to produce electric touch to human body by the work of the control touch feedback of processor 40 electrode layer 20
Feedback；And make by the setting touch control electrode layer 30 on touch-screen 100 and by the control work of touch control electrode layer 30 of processor 40
Touch-screen 100 can realize suspension procedure.Secondly, when the control touch-screen 100 of processor 40 provides first to be operated, processor 40
Also controlling touch feedback electrode layer 20 to be grounded by second circuit 60 makes touch feedback electrode layer 20 play touch control electrode layer 30
Shielding action, such touch control electrode layer 30 and touch control capacitance have accuracy of identification higher, improve user's operation touch-screen 100
Distance.When the control touch-screen 100 of processor 40 provides second to be operated, processor 40 also controls touch-control by the first circuit 50
The ground connection of electrode layer 30 makes touch control electrode layer 30 that shielding action, such touch feedback electrode layer 20 are played to touch feedback electrode layer 20
And touch feedback electric capacity has accuracy of identification higher, enhance touch feedback electrode layer 20 and imitated to the electric touch that human body is produced
Really.

Human body realizes frequency that the corpuscula lamellosa of sense of touch to be experienced, most sensitive in feedback；When the frequency of low frequency component does not exist
When in the range of 10Hz-500Hz, what human body was subject to experiences the DeGrain of electrotactile stimulation.High fdrequency component is mainly used in right
Low frequency component is modulated, in the presence of the high fdrequency component, the frequency range due to the frequency higher than the hearing of people, therefore energy
User is enough avoided to hear the noise that equipment is produced；Detection signal is fed back in the presence of high fdrequency component simultaneously can reduce touch-control circle
Face surface is dirty and the influence of steam etc. and can be used in strengthening the effect of the electrotactile stimulation that human body is subject to；When feedback is detected
When the frequency of signal is not in the range of 10KHz-500KHz, user can hear the electric touch that equipment can produce noise and user to be subject to
The DeGrain of stimulation.The touch control detection cycle, corresponding detection frequency was 1000Hz-1MHz, corresponding when the touch control detection cycle
When frequency is 1000Hz-1MHz, touch-screen 100 can preferably detect suspension procedure of the user to touch-screen 100；While touch-control
Frequency is easy to perform in the gap that position detection is arranged between feedback detection, and then be easy to reality more than the frequency of low frequency component
Now feedback detection is detected in real time with position detection；When touch control detection cycle corresponding frequency is not in 10KHz-500KHz scopes
When interior, touch-screen 100 detects that suspension procedure response of the user to touch-screen 100 is too fast or causes to efficiently identify slowly excessively
User is in the suspension procedure to touch-screen 100.
