Abstract

The utility model discloses a screen anti-peep protection membrane which is of a three-layer structure, wherein the first layer is a PET (polyethylene terephthalate) vision surface layer; the second layer comprises a plurality of UV (ultra violet) resin units which are fixed on the surface of the first layer in parallel by adopting great glue; and the third layer is a PET base layer. By adopting an ultra-fine window-blinds optical polarized light principle technology, people which watch the range of 30 degrees around of the screens of computers, cell phones, ATMs (automatic teller machines) and the like can see contents on the screens clearly, people aside can see a dark picture, and commercial confidential and personal privacy are protected all-dimensionally; and the screen anti-peep protection membrane is much free to use, is simple in structure, is low in production cost, and is suitable for production on a large scale.

Description

The anti-peeping diaphragm of a kind of screen

Technical field

The utility model relates to a kind of optics polarisation principle technical field, relates in particular to the anti-peeping diaphragm of a kind of electronic curtain.

Background technology

Screen protecting film is a kind of transparent medium of using; main employing PET is former material at present, and the ordinary screen diaphragm only plays the effect of dust protection, along with the continuous progress of social technology; people more and more pay attention to quality, the safety of life; people browse by computer, cellphone information, operations such as inquiring about, deposit, withdraw the money at the ATM automatic teller machine, because of the screen visible angle larger; information is easy to be obtained by other people; refer more particularly to the information of some confidentialities, an amount is revealed, and causes immeasurable loss.

Existing screen only has simple dustproof, scratch resistant function, does not possess the difference of utilizing the visual angle and makes screen become the diaphragm of not visible state.

The utility model content

The technical problems to be solved in the utility model be to provide a kind of about 60 degree angular ranges not visible anti-peeping diaphragms of screen.

For solving the problems of the technologies described above; the utility model is realized by following scheme: the anti-peeping diaphragm of a kind of screen; described anti-peeping diaphragm is three-decker; ground floor is that PET looks surface layer; the second layer adopts on the parallel surface that is fixed on ground floor of high glue for several UV resin unit, and the 3rd layer is the PET bottom.

Described UV resin unit is the trapezoidal column body structure, and it is bonding that its bottom surface and PET look surface layer, and each space, UV resin unit.

Described PET bottom adopts the end face of low glue or high glue and UV resin unit bonding.

Height between the described UV resin unit is consistent.

Interval width between the described UV resin unit is consistent.

The utility model has the advantages that: adopt ultra tiny shutter optics polarisation principle technology; can only allow screens such as facing computer, mobile phone, ATM about the clear content of seeing on the screen of 30 degree scope persons; the people of side sees it being picture as dark as a stack of black cats; omnibearing protection trade secret and personal privacy right; use more leisurely and carefree; and simple in structure, production cost is low, is fit to large batch of production.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the anti-peeping diaphragm structural representation of the utility model screen;

Fig. 2 is the anti-peeping diaphragm schematic diagram of screen in the utility model side direction 60 degree scopes.

The specific embodiment

As shown in Figure 1, the anti-peeping diaphragm of a kind of screen, described anti-peeping diaphragm is three-decker, and ground floor is that PET looks surface layer 1, and the second layer is fixed on the surface of ground floor for several UV resin unit high glue of 2 employings are parallel, and the 3rd layer is PET bottom 3.Described UV resin unit 2 is the trapezoidal column body structure, the UV resin unit 2 of ladder type mainly is better than the light transmittance of rectangle cylinder, it is bonding that its bottom surface and PET look surface layer 1, and each 2 space, UV resin unit and interval width are consistent, and PET bottom 3 adopts the end face of low glue or high glue and UV resin unit 2 bonding.

Embodiment 1:

As shown in Figure 2, ground floor PET looks surface layer 1 over against people's visual angle, visual range be direction shown in the arrow up and down each 30 the degree in, exceeding described scope is, side surface direction 60 degree are pitch-dark picture, thereby the information that effectively reduces is by the probability that other people obtain, and realization information, especially confidential information can be relieved, browse freely.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
