A kind of touch panel of two-sided blind hole finger print safety identification of the utility model the utility model has the advantages that on touch panel nothing
Through-hole need to be opened up, can effectively avoid dust between fingerprint identification module and through-hole in existing gap entry communication equipment
Portion, while two sides open up blind hole respectively can effectively realize waterproof, and then can preferably guarantee that fingerprint identification module is normal
Work.Furthermore it can be provided simultaneously with the advantages of thoughts touch and save space, the setting of thickness of glass is relatively flexible at blind hole, favorably
In the sensitivity for adjusting fingerprint recognition.Production process is simple, and technology difficulty is small, yield and high production efficiency, and production cost reduces.
Detailed description of the invention:
Fig. 1 is a kind of structural schematic diagram of the touch panel of two-sided blind hole finger print safety identification of the utility model；
In figure: 1- glass cover-plate, the first blind hole of 2-, the second blind hole of 3-, 4- conductive circuit layer, 5- fingerprint recognition chip, 6-
Flexible circuit board, 7- stiffening plate.
Specific embodiment:
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot understand
For its relative importance of indication or suggestion or implicitly indicate the quantity of indicated technical characteristic.Define as a result, " first ",
The feature of " second " can explicitly or implicitly include at least one of the features.In addition, the technical side between each embodiment
Case can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when the combination of technical solution
