[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, most of the existing electronic devices such as mobile phones or tablets have a fingerprint identification area disposed under a display screen, and the electronic device can be unlocked by touching the fingerprint identification area of the display screen. The first embodiment of the present invention provides a peep-proof film 100, which adopts the existing optical technology of ultra-fine blind, and is implemented by arranging the grating structure side by side, wherein the grating is usually formed by peep-proof materials such as resin and color paste through rolling and fixing by a mold, and is gray black, and the interval of the grating is usually 0.02-0.1 mm. The adjustment of the visible angle can be realized by adjusting the interval of the grating, and the adjusted visible angle range is usually 25 degrees to 60 degrees, specifically 25 degrees, 30 degrees and 45 degrees. The smaller the visual angle is, the better the peep-proof effect is. By arranging the grating structures at different angles, diversified use requirements can be met.
When the peep-proof film 100 is used, when the peep-proof film 100 is attached to a display screen of an electronic device and a picture of the electronic device is viewed, information of the picture of the display screen can be clearly seen, at the moment, the display screen of the electronic device only has visibility within a visual angle of two sides by taking the front side and the front side as a center, and the display screen information of the electronic device cannot be seen from the side faces outside the visual angle and has peep-proof performance, and any person can only see a blackish picture by viewing from the two sides, so that the peep-proof film 100 is peep-proof and can prevent glare in the using process.
Referring to fig. 1, the privacy film 100 includes at least two layers, namely a substrate layer 101 and a privacy layer 102. The base material layer 101 adopts a film with a thickness of 0.1mm-1mm as a base film of electronic equipment such as a mobile phone or a flat panel, optionally, the thickness of the film can be 0.1mm, 0.3mm, 0.5mm or 0.8mm, and the film material can be organic glass material, toughened glass material, PP material, PVC material, PET material or ARM material.
The peep-proof layer 102 is arranged on one surface of the substrate layer 101 and comprises an identification area 1021 and a peep-proof area 1022 arranged around the identification area 1021, the peep-proof area 1022 is a grating structure formed by a peep-proof material on the substrate layer 101, and the identification area 1021 is not provided with the peep-proof material and is aligned with a fingerprint identification area of a corresponding mobile phone or a tablet and other electronic equipment. The surface area of the identification area 1021 is generally smaller than or equal to a circle or an ellipse with a radius of 1cm, that is, the radius size of the identification area 1021 is 0.3-1.5cm, and the specific position of the identification area 1021 should be set according to the position of a fingerprint identification area of an electronic device such as a mobile phone or a tablet. The thickness of the peep-proof layer 102 is 0.15-0.6mm, specifically 0.15mm, 0.25mm, 0.35mm, 0.45mm or 0.6 mm.

The peep-proof material comprises resin and color paste. In the actual preparation process, the area of the substrate layer 103 corresponding to the identification area 1021 can be covered by an external mask, so that the peep-proof area 1022 and the identification area 1021 are formed after the preparation of the peep-proof layer 102 is completed, and the identification area 1021 can more sensitively identify and sense fingerprints.
The spacing between two adjacent grating structures of the privacy zone 1022 may also be 0.02-0.1mm, specifically the spacing may be 0.02mm, 0.05mm, 0.08mm, and 0.1 mm. Due to the grating structure of the peep-proof region 1022, the light transmission refractive index of the peep-proof region 1022 ranges from 1.00 to 1.50, and optionally, the refractive index may be 1.00, 1.20, 1.30 or 1.50.
And spraying pure silicone rubber on the side of the base material layer 101, which is far away from the peep-proof layer 102, to form an adhesive layer 104. The thickness of the adhesive layer 104 is 25 μm to 80 μm, so as to facilitate the substrate layer 101 to be attached to a display screen of an electronic device such as a mobile phone or a tablet, and optionally, the thickness of the adhesive layer 104 may be 25 μm, 50 μm, 60 μm, or 80 μm. The privacy film 100 further includes a peeling film 103 disposed on a side of the adhesive layer 104 away from the privacy layer 102, and configured to protect the adhesive layer 104 on the substrate layer 101 when the privacy film 100 is not attached to an electronic device such as a mobile phone or a tablet.
In another embodiment of this embodiment, the process for preparing the privacy film 100 may further comprise: the peep-proof material is adopted to prepare the peep-proof layer 102 film with the grating structure under the matching of an external mold and a process. If the privacy layer 102 film obtained by the above preparation process does not have a grating structure in the preparation process in the region aligned with the identification region 1021, the privacy region 1022 and the identification region 1021 are formed on the privacy layer 102 film, and the privacy layer 102 film can be directly attached to the substrate layer 101 as needed, so that privacy can be achieved and fingerprint identification can be better performed.
Referring to fig. 2, a second embodiment of the present invention provides a peep-proof membrane 100, which is different from the first embodiment in that: peep-proof membrane 100 is still including setting up other layer structure such as protective layer 105 on peep-proof layer 102 respectively, and substrate layer 101 is kept away from other layer structure such as protective layer 105 of peep-proof layer 102 one side, through paste layer 104 will protective layer 105 respectively with peep-proof layer 105 and substrate layer 101 is pasted fixedly, protective layer 105 adopts the thin layer that the PE material design formed, possesses the protection against the tide and the moisture permeability is little and multiplicable peep-proof membrane 100's life.
Except for the above-described difference, the other components are the same as the privacy film 100 in the first embodiment.
The other surface of the substrate layer 101, which is opposite to the peep-proof layer 102, is attached to a display screen of an electronic device such as a mobile phone or a tablet, or is matched with other layer structures to play a role of an electronic device protection film.
Therefore, the whole peep-proof film 100 has a peep-proof function except a fingerprint identification area, so that the basic peep-proof requirement of a user is met, the fingerprint identification effect is not influenced, the fingerprint identification sensing capacity is even improved, and the more comfortable experience of the user is promoted.
It is understood that the privacy film 100 has a rounded quadrilateral structure or a curved structure suitable for a curved screen or other shapes. The surface area of the privacy film 100 is designed to be adjusted according to the size of the display screen of the electronic device, such as a mobile phone or a tablet, and optionally, 5.5 inches or 6 inches is used for the privacy film 100 suitable for most mobile phones, and 7 inches, 9.7 inches or 12 inches is used for the privacy film 100 suitable for most tablets.
In other embodiments, when a Home e key appears in an electronic device such as a mobile phone or a tablet as a fingerprint identification area of the electronic device such as the mobile phone or the tablet, the peep-proof film 100 is designed to be hollow where the structure of the peep-proof layer 102 is aligned with the Home e key of the electronic device such as the mobile phone or the tablet, that is, the identification area 1021 does not need to be arranged on the peep-proof layer 102 of the peep-proof film 100.
