Abstract

The utility model discloses a peep-proof film. The peep-proof film comprises a polyethylene terephthalate (PET) layer, a resin bottom layer and an ultraviolet (UV) resin layer, wherein the UV resin layer comprises a plurality of lines of UV resin units; and the PET layer is arranged on one surface of the resin bottom layer, and a plurality of lines of UV resin units which are spaced from one another are paved on the other surface of the resin bottom layer. Each UV resin unit is a cuboid, and all the UV resin units are parallelly arranged on the surface of the resin bottom layer. The peep-proof film adopts an optical polarizing principle technology, so that a computer screen is specially used for a user to read from a front 60-degree viewing angle, namely the data on the screen cannot be seen clearly from two sides beyond left 30 degrees and right 30 degrees (the invisibility beyond 30 degrees means that when seen from the left side, the data on the screen is invisible from an angle beyond 30 degrees from the far left side of the screen, and when seen from the right side, the data on the screen is invisible from an angle beyond 30 degrees from the far right side of the screen), business secrets and the personal privacy are protected, and a computer can be used more freely and comfortably.

Description

A kind of peep-proof film

Technical field

The utility model belongs to optics polarization light technology field, relates to a kind of peep-proof film, relates in particular to a kind of peep-proof film of electronic product screen.

Background technology

Nowadays, electronic products such as computer, mobile phone have incorporated in the middle of people's work and the life, for people provide a lot of convenience.Yet when people passed through the screen browsing information of electronic product, the information of browsing was easy to obtained by other people (because the angle of visibility of screen is bigger at present); Especially for the information of some confidentialities, the user of electronic equipment does not hope that more above-mentioned information seen by other people.

Existing screen protection film does not have the peep-proof function usually, makes that the confidentiality of screen message is very poor, the screen protection film that does not also well have the peep-proof function at present.

The utility model content

The utility model technical problem to be solved is: a kind of peep-proof film is provided, can protects trade secret and personal privacy right effectively, use computer more leisurely and carefree.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of peep-proof film, said peep-proof film comprises: pet layer, resin bottom, UV resin bed; The UV resin bed comprises some row UV resins unit; The one side of said resin bottom is provided with pet layer, and another side is equipped with the UV resin unit of some row space.

As a kind of preferred version of the utility model, said UV resin unit is cuboid or prism, and each UV resin unit is set in parallel on the surface of resin bottom.

As a kind of preferred version of the utility model, be air between each UV resin unit.

As a kind of preferred version of the utility model, each UV resin unit interval distance is the 5-100 micron, and the width of each UV resin unit is the 5-100 micron, and the height of each UV resin unit is the 5-200 micron.

Further, each UV resin unit interval distance is 25 microns, and the width of each UV resin unit is 50 microns, and the height of each UV resin unit is 100 microns.

As a kind of preferred version of the utility model, be provided with the two UV resin unit different between each UV resin unit with UV resin unit refractive index.

Further, the width of each UV resin unit is the 5-100 micron, and the width of each the 2nd UV resin unit is the 5-100 micron; The height of each UV resin unit, the 2nd UV resin unit is identical, is the 5-200 micron.

As a kind of preferred version of the utility model, the width of each UV resin unit is 50 microns, and the width of each the 2nd UV resin unit is 25 microns; The height of each UV resin unit, the 2nd UV resin unit is 100 microns.

As a kind of preferred version of the utility model, the height of each UV resin unit is consistent.

As a kind of preferred version of the utility model, the width of each UV resin unit is consistent.

The beneficial effect of the utility model is: the peep-proof film that the utility model proposes, and Application Optics polarisation principle technology makes computer screen specialize in the user and reads from positive 60 degree visual angles; 30 degree do not see data on the screen (invisible being meant when the left side is seen beyond 30 degree with external both sides promptly; Apart from invisible beyond screen Far Left 30 degree, when the right is seen) apart from invisible beyond screen rightmost 30 degree; Protection trade secret and personal privacy right use computer more leisurely and carefree.

Fig. 3 is the schematic cross-section of peep-proof film among the embodiment two.

The specific embodiment

Specify the preferred embodiment of the utility model below in conjunction with accompanying drawing.

Embodiment one

See also Fig. 1, Fig. 2, the utility model has disclosed a kind of peep-proof film, and said peep-proof film comprises: pet layer 10, resin bottom 20, UV resin bed; The UV resin bed comprises some row UV resins unit 30; The one side of said resin bottom 20 is provided with pet layer 10, and another side is equipped with the UV resin unit 30 of some row space.

In the present embodiment, said UV resin unit 30 is cuboid or prism, and each UV resin unit 30 is set in parallel on the surface of resin bottom.

Part can be an air between the UV resin unit 30, also can be the 2nd UV resin unit 40 (for the UV moulding resin); Part is when being the 2nd UV resin unit 40 between the UV resin unit 30, the refractive index difference of the refractive index of the 2nd UV resin unit 40 and UV resin unit 30 greatly (as, can be between the 0.1-1).

Each UV resin unit 30 spacing distance is the 5-100 micron, and the width of each UV resin unit 30 is the 5-100 micron, highly for the 5-200 micron.In the present embodiment, each UV resin unit 30 spacing distance is 25 microns, and the width of each UV resin unit 30 is 50 microns, highly is 100 microns.

When part was the 2nd UV resin unit 40 between the UV resin unit 30, the height of each UV resin unit 30, the 2nd UV resin unit 40 can be identical, is the 5-200 micron.

Preferably, the height of each UV resin unit 30 is consistent, width is consistent, spacing is consistent; Certainly, the height of each UV resin unit 30, width, spacing also can be inconsistent respectively.
