Description
Technical Field
The utility model relates to a fingerprint identification technical field especially relates to a protection architecture of fingerprint identification module.
Background
Fingerprint identification is being used more and more extensively as an identification's mode, and when carrying out fingerprint identification, the user need put the finger in appointed identification area for fingerprint sensor discernment, but current protective film material is single relatively thin soft fragile, and structural strength is low, and easy because the scraping wearing and tearing appear of the impact that does not survive external force, the broken condition of even taking place can not play fine guard action to the fingerprint identification module.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, provide a protection architecture of fingerprint identification module, compact structure and structural strength are high, play fine guard action to the fingerprint identification module, possess good resistant scraping, dirty characteristic of preventing.
In order to realize the above purpose, the utility model discloses a protection architecture of fingerprint identification module, from type rete, black PET membrane, fingerprint protection film and PET from the type rete down are stacked gradually including from top to bottom and are provided with PET in proper order, be provided with the double faced adhesive tape between fingerprint protection film and the black PET membrane, fingerprint protection film and PET are provided with PU glue from the type rete down between.
Preferably, the black PET membrane includes the primer layer, the upper surface of primer layer has set gradually first black printing ink layer, second black printing ink layer, first inferior gloss oil layer and second inferior gloss oil layer.
Preferably, the thickness of the black PET film is 0.025 mm.
Preferably, the thickness of the lower PET release film layer is 0.05 mm.
The utility model has the advantages that: the utility model provides a protection architecture of fingerprint identification module, from type rete, black PET membrane, fingerprint protection film and PET from type rete down are stacked gradually including from top to bottom and are provided with PET in proper order, be provided with the double faced adhesive tape between fingerprint protection film and the black PET membrane, fingerprint protection film and PET are provided with PU glue from type between the rete down.
Lower PET is installed at the upper surface at fingerprint identification module from the type rete, lower PET is connected with the fingerprint protection film from the type rete through PU glue, the fingerprint protection film passes through double faced adhesive tape and black PET membrane coupling, the surface of black PET membrane is attached to have PET and is left the type rete, go up PET and leave type rete and can effectively improve overall structure's mechanical strength and structural stability from the type rete with lower PET, black PET film has good light shielding property, adjust the intensity of light, PU glue has from the air release nature, can arrange the bubble fast away, guarantee product quality, the surface of fingerprint protection film distributes densely has countless arch, can alleviate the pressure of fingertip to the touch-sensitive screen, and then do not leave the fingerprint, make the fingerprint protection film not remain the pollutant, and when the finger slides on the fingerprint protection film, the sense of comfortable and smooth and greasy can be experienced. The utility model discloses compact structure and structural strength are high, play fine guard action to the fingerprint identification module, possess good resistant scraping, dirty characteristic of preventing.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-2, the utility model discloses a protection architecture of fingerprint identification module, from type rete 1, black PET membrane 2, fingerprint protection film 3 and PET from type rete 4 down including from top to bottom stacking gradually and being provided with PET, be provided with double faced adhesive tape 5 between fingerprint protection film 3 and the black PET membrane 2, fingerprint protection film 3 and PET are provided with PU glue 6 from type rete 4 down between.
Lower PET is installed at the upper surface at fingerprint identification module from type rete 4, lower PET is connected with fingerprint protection film 3 through PU glue 6 from type rete 4, fingerprint protection film 3 is connected with black PET membrane 2 through double faced adhesive tape 5, the surface of black PET membrane 2 is attached to have PET to leave type rete 1, it leaves type rete 1 and lower PET and can effectively improve overall structure's mechanical strength and structural stability from type rete 4 to go up PET, black PET membrane 2 has good light shielding nature, adjust the intensity of light, PU glue 6 has from the air discharge, can discharge the bubble fast away, guarantee product quality, the surface intensive distribution of fingerprint protection film 3 has countless arch, can alleviate the pressure of fingertip to the touch-sensitive screen, and then do not leave the fingerprint, make fingerprint protection film 3 not remain the pollutant, and when the finger slides on fingerprint protection film 3, the sensation of comfortable smoothness is felt. The utility model discloses compact structure and structural strength are high, play fine guard action to the fingerprint identification module, possess good resistant scraping, dirty characteristic of preventing.
As shown in fig. 1 and 2, the black PET film 2 of the present embodiment includes a primer layer 21, and a first black ink layer 22, a second black ink layer 23, a first matte oil layer 24, and a second matte oil layer 25 are sequentially disposed on an upper surface of the primer layer 21. Specifically, primer layer 21 makes first black printing ink layer 22 and second black printing ink layer 23 bond firmly, adopts twice black printing ink layer, and the colourity is even, the shielding nature is good, adopts twice matte oil layer, on the basis of further increasing the degree of consistency, plays the guard action to black printing ink layer, is difficult for the fish tail, and never fades.
As shown in FIG. 1, the black PET film 2 of the present embodiment has a thickness of 0.025 mm. Specifically, the thickness of the black PET film 2 is 0.025mm, the material is light and thin, the flexibility is good, and the service performance is good.
As shown in fig. 1, the thickness of the lower PET release film layer 4 of the present embodiment is 0.05 mm. Specifically, lower PET is 0.05mm from the thickness of type rete 4, has good adhesion performance, can laminate repeatedly and do not have the residue on the fingerprint identification module.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
