Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the embodiments of the present application more clearly apparent, the present application is further described in detail below with reference to fig. 1 to 6 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship indicated in the drawings that is solely for the purpose of facilitating the description of the embodiments and simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the application.
First embodiment
Referring to fig. 1 and 6, the present embodiment provides a protective film 100 for a fingerprint recognition intelligent terminal, which is bonded on a screen of the fingerprint recognition intelligent terminal 200, so as to protect the fingerprint recognition intelligent terminal 200 and ensure that the fingerprint recognition function of the fingerprint recognition intelligent terminal 200 is effective.
Referring to fig. 1, the protective film 100 of the present embodiment includes a protective layer 1 and an adhesive layer 2.
Referring to fig. 6, the protection layer 1 is used to protect a screen of the fingerprint recognition smart terminal 200. The material of the protective layer 1 may be sapphire glass, ceramic glass, microcrystalline glass, aluminosilicate glass, soda-lime glass, acryl, or Polycarbonate (PC). In the present embodiment, the protective layer 1 is sheet-like.
Referring to fig. 3 and 4, an adhesive layer 2 is used to adhere the protective layer 1 to the screen of the fingerprint recognition smart terminal 200. In this embodiment, the adhesive layer 2 is a layer of AB glue; in other embodiments, the adhesive layer 2 is a layer of other types of adhesives. The front face 21 of the adhesive layer 2 is adhered to the back face 12 of the protective layer 1. The back surface 22 of the adhesive layer 2 is used for adhering to the screen of the fingerprint identification smart terminal 200.
Referring to fig. 3, the front surface 11 of the protective layer 1 is provided with a sink 13 for fingerprint recognition. When the smart terminal 200 detects that the bottom surface 131 of the sinking groove 13 contacts with the fingerprint of the user, the smart terminal 200 performs fingerprint recognition.
Referring to fig. 4, the distance between the bottom surface 131 of the sinker 13 and the back surface 12 of the protective layer 1 is the sinker bottom thickness 132. The distance between the bottom surface 131 of the sink 13 and the front surface 11 of the protective layer 1 is the sink depth 133. The sum of the thickness 132 of the bottom of the sinking groove and the thickness 20 of the adhesive layer 2 is less than or equal to the set thickness.
The formation of the sink 13 will be explained. And (3) grinding the surface of the toughened glass with the thickness of 0.33mm by using a CNC grinding head to form a sinking groove 13 at a position corresponding to the fingerprint identification of the intelligent terminal. Referring to fig. 5, the overall size of the sinking groove 13 is the same as or slightly larger than the size of the fingerprint identification area 201 (or the identification area of the fingerprint under the screen) on the screen of the smart terminal. The depth of the sink 13, i.e. the sink depth 133, is greater than 0.18mm, so that the sink bottom thickness 132 is less than 0.15 mm.
After finishing the processing of the sink 13, the glass is polished, cleaned, tempered and the like, and the protective layer 1 thus obtained is a tempered glass sheet. Wherein the thickness of the region of the protective layer 1 except the sink 13 is 0.33 mm. Finally, a piece of 0.25mm AB glue is attached to the back 12 of the glass, i.e. the protective layer 1, to obtain the protective film 100. The thickness of the position of the protective film 100 corresponding to the fingerprint identification area is less than or equal to (i.e., not greater than) the set thickness, i.e., 0.4mm, so that the purpose of not affecting the fingerprint identification rate under the screen can be achieved.
According to the above, the thickness of the glass is locally reduced under the state that the through hole is not opened in the glass, so that the fingerprint identification of the intelligent terminal is not influenced, the strength of the toughened protective film is not changed, the impression is not influenced, and meanwhile, the risk that the intelligent terminal falls to break a screen or scratch can be reduced.
In an embodiment, referring to fig. 1, the sink 13 is located at a lower portion 1A of the front surface 11 of the protective layer 1.
Referring to fig. 2, the shape of the sink 13 may be a square, a circle, a funnel, an ellipse, a trapezoid, or a polygon having more than four sides.
The undercut 13 may be formed by chemical etching, partial polishing, or laser cutting, in addition to being formed by CNC (computer Numerical Control) grinding.
The embodiment provides a can protect screen can not fish tail and do not influence the tempering protection film of fingerprint identification under the screen again, can solve the technical problem that the fingerprint identification rate is low behind the smart mobile phone pad pasting of fingerprint under the carrying screen.
Second embodiment
Referring to fig. 6, the present embodiment provides a fingerprint recognition smart terminal 200. A fingerprint identification area 201 is arranged on the screen of the fingerprint identification intelligent terminal 200. The protective film 100 is adhered to the screen of the fingerprint identification intelligent terminal 200, and the protective film 100 covers the fingerprint identification area 201. With the protective film 100, the area of the bottom surface 131 of the sink 13 is greater than or equal to the area of the fingerprint identification region 201.
The fingerprint identification smart terminal 200 has a fingerprint identification function, and may be a smart phone, a tablet computer or a wearable device.
Some technical solutions in the prior art are explained below.
In order to avoid affecting fingerprint unlocking of existing mobile phones with fingerprints under screens, PET (polyethylene terephthalate) flexible films are mostly pasted. However, the film cannot resist falling and has poor scratch resistance.
Another solution in the prior art: a piece of 0.075 PET is pasted on the back of the glass with the thickness of 0.21mm, and then a piece of 0.075mm double-sided adhesive tape is pasted on the edge of the glass for adhering the mobile phone; thus, an air layer is arranged between the mobile phone cover plate and the protective plate, and Newton rings are generated to influence the appearance; the edge of the protection sheet has obvious glue marks, which affects the appearance; the glass is too thin and is easy to break, and the protection effect on the mobile phone is limited.
To the scheme that sets up the through-hole on the protective film among the prior art, can scrape the hand during unblock, still can save the dust, influence the use.
The foregoing is a further detailed description of the present application in connection with specific/preferred embodiments and is not intended to limit the present application to that particular description. For a person skilled in the art to which the present application pertains, several alternatives or modifications to the described embodiments may be made without departing from the concept of the present application, and these alternatives or modifications should be considered as falling within the scope of the present application.
