Description
Technical field
The utility model relates to touch screen technical field, particularly relates to a kind of fingerprint recognition touch screen.
Background technology
Existing touch screen with fingerprint fingerprint inductor and control chip is enclosed in a becket, the panel of touch screen made a call to a through hole, fingerprint identification device is fixed on this through hole.Because panel is got through hole by needs, can affect structural strength around through hole to the panel of glass material, then also can affect outward appearance to the panel of plastic cement material; And panel has through hole, and sweat, tiny foreign material etc. easily infiltrate through through hole and affect the reliability of fingerprint identification device.In addition, in prior art, fingerprint identification device is also a part for Total Product outward appearance, and its color and physical dimension are restricted.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of fingerprint recognition touch screen, can avoid perforate on the panel of touch screen.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of fingerprint recognition touch screen, comprise panel and fingerprint identification device, the back side of described panel is also provided with a groove, fingerprint identification device is provided with in described groove, described fingerprint identification device comprises the fingerprint recognition chip be located in groove, and described fingerprint recognition chip is also wired to the main control chip of touch screen.
Further, described panel be glass or plastic material transparent protective substrate or on transparent protective substrate a side surface be provided with the OGS touch screen main body that conductive film layer and sensor formed.
Further, the front of described panel is provided with pattern for identification fingerprint recognizing site or word corresponding to the position of described fingerprint identification device.
Further, described groove is the decanter type groove by cutting or etch formation.
Further, described fingerprint recognition chip by non-conductive adhesive be pasted on conductive ink layer around region in groove floor on.
Further, described groove floor is also being provided with ringwise by edge and the conductive ink layer arranged around described fingerprint recognition chip, and the contact of described fingerprint recognition chip contacts with conductive ink layer.
Further, described conductive ink layer is formed at the surrounding of groove by edge by the printing of seal typography.
After adopting technique scheme, the utility model at least has following beneficial effect: because fingerprint identification device is arranged in the groove of back side of panel, and panel, without the need to getting through hole, can keep the complete outward appearance of panel; Fingerprint identification device in the utility model is arranged at back side of panel, does not need the direct contact of human body, is not vulnerable to the dipping of sweat stain and moisture and impaired; Being in the fingerprint recognition induction of back side of panel and the color of control section and physical dimension can not be restricted.
Accompanying drawing explanation
Fig. 1 is the back side of panel structural representation of the utility model fingerprint recognition touch screen.
Fig. 2 is the panel front structural representation of the utility model fingerprint recognition touch screen.
Fig. 3 is the panel cross-sectional view of the utility model fingerprint recognition touch screen.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined with each other, and are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, the utility model provides a kind of fingerprint recognition touch screen, comprises panel 1 and fingerprint identification device 2.
The back side of described panel 1 is also provided with a groove 3, and described groove 3 can be by the decanter type groove cut or the technique such as etching is formed.Usually, described panel 1 can adopt traditional protective substrate by glass or plastic material manufacture.And in certain embodiments, the back side of panel 1 also can be provided with functional sheet 4 further, such as realize conductive film layer and the sensor of touch controllable function, thus the OGS touch screen main body formed, this fingerprint identification device 2 also can be arranged on functional sheet 4, as adopted the touch screen of single layer structure, panel 1 and functional sheet 4 will be simplified to a slice panel.
Namely described fingerprint identification device 2 is arranged in described groove 3.Described fingerprint identification device 2 comprise to be located in groove 3 by edge ringwise conductive ink layer 20 and be located at conductive ink layer 20 around region in fingerprint recognition chip 22, the contact of described fingerprint recognition chip 22 contacts with conductive ink layer 20, and described fingerprint recognition chip 22 is also connected to the main control chip (scheming not shown) of touch screen by wire 24.
During concrete enforcement, described conductive ink layer 20 can be formed at the surrounding of groove 3 by edge by the printing of seal typography.Described fingerprint recognition chip 22 then can by non-conductive adhesive 26 be pasted on conductive ink layer 20 around region in groove 3 bottom surface on.Certainly, in certain embodiments, according to the difference of adopted fingerprint recognition chip 22, also conductive ink layer 20 can not also be set, thus structure can be made more succinct.
For convenience of operation, the pattern for identification fingerprint recognizing site or word 10 also can be printed in the position corresponding to described fingerprint identification device 4 in the front of described panel 1.Thus user can be guided at the position of this mark pressing finger to carry out fingerprint recognition.
Because fingerprint identification device 2 is arranged in the groove 3 at panel 1 back side, panel 1, without the need to getting through hole, can keep the complete outward appearance of panel 1; Fingerprint identification device 2 in the utility model is arranged at panel 1 back side, does not need the direct contact of human body, is not vulnerable to the dipping of sweat stain and moisture and impaired; The size being in the fingerprint identification device at panel 1 back side can not be restricted.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is limited by claims and equivalency range thereof.
