Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
Shown in Figure 1, compound touch controlled key 100, include the most successively from upper (close to finger side)
Dielectric layer 101, capacitance sensor 102 (including multiple capacitive sensing electrode), dielectric layer 103, pressure
Sensor 105, and the support member 104 of both sides.Its dielectric layer 101 is usually glass cover-plate, and electric capacity passes
Copper Foil sensor on sensor 102 generally PCB, dielectric layer 103 generally PCB substrate, pressure passes
Sensor 105 generally composite pressure-sensitive material layer, and print on flexible substrates；Support member 104 is for giving pressure
Force transducer 105 provides deformation space, thus strengthens pressure sensitive sensitivity.Capacitance sensor 102 and
Pressure transducer 105 is both needed to be electrically connected to respective handling circuit by wire, and this is common knowledge, therefore figure
Not shown in；It addition, the connector between above layers is also prior art it is achieved that such as some layer
Between be by glue bond, some is then by sedimentation stacking etc., different bonding, stack manner not shadow
Ring the present invention to implement, therefore repeat no more.
Additionally, the first inductive layer is not limited to capacitance touch button sensor, it can also be fingerprint Identification sensor.
Shown in Figure 2, it is combined cell phone apparatus 200 example of touch controlled key for a kind of application, at this mobile phone
In equipment 200, shell 201 is fixed and the protection of internal part for appearance and modeling, structure；Shell 201
Front openings is used for placing display screen 202；In the bottom in shell 201 front, compound touch controlled key 100 is installed,
For the HOME key as mobile phone.
See Fig. 3, realize the first control method of compound touch controlled key for the present invention in cell phone apparatus.Tool
The rate-determining steps of body is as follows:
Step S101: obtain the touch signal of the first inductive layer；
Step S102: determine whether touch signal, if not having, then process ends；Otherwise enter next
Step；
Step S103: obtain the second inductive layer signal；
Step S104: determine whether to press signal；If having, enter step S106；Otherwise enter S105
Carry out time-out to judge；
Step S105: time-out detection；Have not timed out then repetition step S104, otherwise enter step S107；
Step S106: perform the scheduled operation that pressing is corresponding: return homepage；
Step S107: perform to touch corresponding scheduled operation, after touch signal disappears, performs to return upper one
Layer.
By above method, so that compound touch controlled key realizes multiple interactive function, improve man-machine
Interactive efficiency；Meanwhile, pressing operation, it is necessary to could be responded, the most illegally after touch operation occurs
Collide with, the pressing etc. of non-staff will be shielded, and decreases the possibility of false triggering.
See Fig. 4, realized the second control method of compound touch controlled key, the tool of the method by the present invention
Body rate-determining steps is as follows:

Step S202: determine whether touch signal, if not having, then process ends；Otherwise enter next
Step；
Step S203: obtain the second inductive layer signal；
Step S204: determine whether to press signal (threshold decision, if more than pressing grade 1)；If having,
Enter step S206；Otherwise enter S205 and carry out time-out judgement；
Step S205: time-out detection；Having not timed out then repetition step S204, otherwise this flow process terminates；
Step S206: the press pressure peak value of detection time period is judged, if be pressing grade 1,
If so, step S207 is performed；Otherwise perform step S208；
Step S207: judge to press as pressing grade 1, the scheduled operation that execution touch is relevant: return upper
Layer；Then process ends；
Step S208: judge to press as pressing grade 2, execution pressing associative operation: return homepage；Then
Process ends.
Above method is judged by pressing grade, and touch signal has carried out trigger protection, only tactile when detecting
When touching signal and reach the pressing signal pressing grade 1, just corresponding touch action, so can effectively prevent
The false triggering that such as skin capacitance when water smoke covers, ambient humidity changes, pocket next to the skin is placed brings.Should
Mode can provide certain protection to the false triggering of capacitance touch.In the present embodiment, grade 1 and grade 2
All represent priority level, pressing grade 2 signal for press pressure more than pressing grade 1.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
