It can be the colors such as red, blue, black, gold.Further, the material of middle paint layer 264 further includes having fluorescer, fluorescer
Such as one of can be zinc sulphide, calcium sulfide, strontium sulfide or a variety of, in the middle paint layer 264 by natural light, daylight light,
After the irradiation such as ultraviolet light, fluorescer can store luminous energy, and after stopping being irradiated by light, then slowly in a manner of fluorescence
Luminous energy is released, the duration for discharging fluorescence can be up to a few houres to ten a few houres, without consuming additional electric energy.
In this way, even if the dark place weaker in light intensity, user can still rely in the fluorescence that issues of paint layer 264 accurately know fingerprint
It identifies the position of mould group 20, and can further place a finger on identification in fingerprint recognition mould group 20 and save fingerprint to unlock
The duration of identification and the success rate for improving fingerprint recognition.Since protective film 26 exposes from the through-hole 18 of shell 10, protective film 26
It is formed on fingerprint recognition chip 22, the fluorescence that the middle paint layer 264 of protective film 26 issues will not be hidden by shell 10, circuit board 24 etc.
Gear, fluorescence are easy to be seen by the user.
Top coat layer 266 is formed on middle paint layer 264, and top coat layer 266 exposes from shell 10, and top coat layer 266 can be light transmission
, the fluorescence that middle paint layer 264 issues can pass through top coat layer 266.Top coat layer 266 can use and the material of middle paint layer 264
The material of characteristic close, the material of top coat layer 266 for example can be epoxy resin or modified epoxy, so that top coat layer
Adhesion strength between 266 and middle paint layer 264 is stronger, avoids top coat layer 266 from separating with middle paint layer 264, while top coat layer 266 has
The performance of preferable anti-scratch, anticracking etc..Specifically, top coat layer 266 covering in paint layer 264 outer surface 2644, that is to say, that
Top coat layer 266 is bonded with the outer surface 2644 of middle paint layer 264 so that the bonded area of top coat layer 266 and middle paint layer 264 compared with
Greatly, the adhesion strength of the two is stronger, at the same in will not reducing paint layer 264 and prime coat 262 bonded area.
Fig. 2 and Fig. 3 are please referred to, when making fingerprint recognition mould group 20, fingerprint recognition chip 22 first can be mounted on electricity
On road plate 24, then protective film 26 is prepared on fingerprint recognition chip 22.Specifically, when preparing protective film 26, can first refer to
Then spray-applied primer material on the upper surface of line identification chip 22 toasts primer material to obtain prime coat 262, primer material can
To be sprayed after ultrasonic atomizatio to fingerprint recognition chip 22 by ultrasonic spray nozzle；It, can be in priming paint after forming prime coat 262
Paint material, middle paint material include above-mentioned fluorescer, toner or mill base etc. in spraying on layer 262, then paint material in baking
To obtain middle paint layer 264, middle paint material can be sprayed after ultrasonic atomizatio to prime coat 262 by ultrasonic spray nozzle；It is formed
After middle paint layer 264, can on middle paint layer 264 spray paint material, then toast topcoat material to obtain top coat layer 266, face
Paint material can be sprayed after ultrasonic atomizatio to middle paint layer 264 by ultrasonic spray nozzle.
To sum up, in the terminal 100 of embodiment of the present invention, due to containing fluorescer in middle paint layer 264 and can issue glimmering
Light, fluorescence enter the external world after passing through top coat layer 266, and when extraneous environment is darker, user can judge fingerprint by fluorescence
It identifies the position of mould group 20, and then accurately places a finger in specified identification region, improve recognition success rate, shorten identification
Duration.
Fig. 5 and Fig. 6 are please referred to, in some embodiments, top coat layer 266 includes multiple sub- top coat layers 2662, every height
Top coat layer 2662 includes anti-fingerprint reagent, anti-in multiple sub- top coat layers 2662 along the direction along separate middle paint layer 264
Fingerprint reagent content is gradually increased.When preparing top coat layer 266, a sub- top coat layer 2662 can be sprayed in middle paint layer 264
And after solidifying the sub- top coat layer 2662, then spray next sub- top coat layer 2662 and solidify this next sub- top coat layer 2662 until
Form complete top coat layer 266.The material of anti-fingerprint reagent may include silicofluoride, and anti-fingerprint reagent can prevent on finger
Moisture and greasy dirt be adhered on top coat layer 266 and (that is to say that top coat layer 266 has the function of anti-fingerprint), meanwhile, compared to each
The mode that the anti-fingerprint reagent of sub- top coat layer 2662 is equal, the anti-fingerprint examination from the farthest sub- top coat layer 2662 of middle paint layer 264
Agent content is higher thus the fingerprint resistance of top coat layer 266 can be more preferably.
Fig. 5 and Fig. 6 are please referred to, in some embodiments, top coat layer 266 includes multiple sub- top coat layers 2662, every height
Top coat layer 2662 includes light-sensitive material, photosensitive in multiple sub- top coat layers 2662 along the direction along separate middle paint layer 264
Material content is gradually reduced.When preparing top coat layer 266, a sub- top coat layer 2662 can be sprayed in middle paint layer 264 and is consolidated
After changing the sub- top coat layer 2662, then sprays next sub- top coat layer 2662 and solidify this next sub- top coat layer 2662 until being formed
Complete top coat layer 266.Light-sensitive material can be polyurethane acroleic acid, can when needing to solidify sub- top coat layer 2662
In the way of replacing baking in a manner of with laser irradiation, the curing time of top coat layer 266 is shortened.Meanwhile compared to each height
The mode that the light-sensitive material of top coat layer 2662 is equal, the light-sensitive material of the innermost layer of the top coat layer 266 of present embodiment contain
It is bigger to measure higher thus top coat layer 266 and the adhesion strength of middle paint layer 264.
