Abstract
The invention discloses an orientation touch device based on an optical type fingerprint head. The orientation touch device comprises a substrate, a back anti-jamming device and a side anti-jamming device. According to the orientation touch device based on the optical type fingerprint head, interference signals of the back and the side edge of an induction contact can be effectively eliminated, the overall anti-jamming capability is greatly improved, and the orientation touch device based on the optical type fingerprint head has wide market prospect in popularization.
Description
Technical field
The present invention relates to fingerprint induction field, particularly relate to a kind of directed touching device based on optical fingerprint head.
Background technology
Existing optical fingerprint head, in order to the residual design of low-power consumption and side, generally all can increase touch function, fingerprint head can be made like this to be in low power consumpting state at ordinary times, and can effectively solve fingerprint residues problem.But the touch function of existing fingerprint head can not realize the directed function touched, as long as namely finger is within induction range, can triggers touch function, greatly can improve the probability of fingerprint false triggering like this.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of directed touching device based on optical fingerprint head, the undesired signal from the back side and side is eliminated respectively by employing back side network and side binding structure, greatly reduce the probability of fingerprint false triggering, improve overall antijamming capability, have market outlook widely popularizing of the directed touching device based on optical fingerprint head.
For solving the problems of the technologies described above, the invention provides a kind of directed touching device based on optical fingerprint head, for the signal disturbing at the back side and side of eliminating touch sensible chip, described touch sensible chip comprises sense contact, comprise: substrate, back side means for anti-jamming and side means for anti-jamming, described sense contact is arranged on the front of described substrate, described back side means for anti-jamming is network and covers the back side of described substrate, described side means for anti-jamming is binding structure and covers the side in the front of described substrate, the material of described back side means for anti-jamming and described side means for anti-jamming is Copper Foil.
In a preferred embodiment of the present invention, the induction mode of described sense contact is capacitive induction.
In a preferred embodiment of the present invention, described back side means for anti-jamming is all connected ground wire with described side means for anti-jamming.
In a preferred embodiment of the present invention, the material of described substrate is glass fabric and epoxy resin.
The invention has the beneficial effects as follows: the directed touching device that the present invention is based on optical fingerprint head can effectively eliminate the back side of sense contact and side undesired signal, substantially increase overall antijamming capability, the directed touching device based on optical fingerprint head universal on have market outlook widely.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Consult Fig. 1, the embodiment of the present invention comprises:
Based on a directed touching device for optical fingerprint head, for the signal disturbing at the back side and side of eliminating touch sensible chip, described touch sensible chip comprises sense contact 1, comprising: substrate 2, back side means for anti-jamming 3 and side means for anti-jamming 4.
Described sense contact 1 is arranged on the front of described substrate 2, described back side means for anti-jamming 3 is network and covers the back side of described substrate 2, described side means for anti-jamming 4 is binding structure and covers the side in the front of described substrate 2, described back side means for anti-jamming 3 and described side means for anti-jamming 4 are respectively used to the undesired signal eliminated from the back side and side, greatly reduce the probability of fingerprint false triggering, improve overall antijamming capability, the material of described back side means for anti-jamming 3 and described side means for anti-jamming 4 is Copper Foil.
Preferably, the induction mode of described sense contact 1 is capacitive induction.
Preferably, described back side means for anti-jamming 3 is all connected ground wire with described side means for anti-jamming 4, when having finger in time producing capacitance signal, this capacitance signal can be discharged into the earth by ground wire by back side means for anti-jamming 3 and side means for anti-jamming 4, thus achieve and eliminate the function of undesired signal, novel structure, convenient and practical.
Preferably, the material of described substrate 2 is glass fabric and epoxy resin.
The beneficial effect that the present invention is based on the directed touching device of optical fingerprint head is:
One, eliminate the undesired signal from the back side and side respectively by employing back side network and side binding structure, greatly reduce the probability of fingerprint false triggering, improve overall antijamming capability;
Two, by adopting Copper Foil as the material of back side means for anti-jamming and side means for anti-jamming and back side means for anti-jamming is connected ground wire respectively with side means for anti-jamming, when having finger in time producing capacitance signal, this capacitance signal can be discharged into the earth by ground wire by back side means for anti-jamming and side means for anti-jamming, thus achieve and eliminate the function of undesired signal, novel structure, convenient and practical.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
