[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0019] Figure 1 It is a structural schematic diagram of an existing privacy film;

[0020] Figure 2 It is a structural schematic diagram of the anti-peep cover structure in one embodiment of the utility model;

[0021] Figure 3 FIG. 2 is a structural schematic diagram of an anti-peep cover structure in another embodiment of the utility model. DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] See also Figure 1 or Figure 2 As shown, an anti-peep cover structure 10 includes: a cover body 100, an anti-peep component 200 and a protective component 300, the cover body 100 has a cover front and a cover back; the anti-peep component 200 includes a first black ink layer 210, the first black ink layer 210 is arranged on the back of the cover, and an anti-peep grating is formed on the first black ink layer 210; the protective component 300 includes a first protective layer 310, and the first protective layer 310 covers the first black ink layer 210.

[0024] It should be noted that if Figure 1 As shown, a privacy film structure 20 is shown, and the privacy film structure includes a protective film 20a, a film substrate layer 20b, a privacy layer 20c, an adhesive layer 20d and a release film layer 20e. Since the privacy film mainly includes a film substrate layer 20b, a privacy layer 20c and an adhesive layer 20d, the thickness of the general privacy film reaches about 400μm. The thickness of 400μm will increase the thickness of the product for products with thinness requirements. Therefore, the utility model directly screen-prints a first black ink layer 210 on the back of the cover body 100, and forms a privacy grating on the first black ink layer, thereby achieving the privacy effect. At the same time, by covering the first black ink layer 210 with a first protective layer 310, the first black ink layer 210 is protected by the first protective layer 310 to avoid the problem of the first black ink layer 210 falling off. In this way, the existing privacy film can be replaced, thereby achieving the effect of reducing the thickness of the display screen. Furthermore, the privacy grating is formed on the first black ink layer by laser engraving, and the structure of the privacy grating is the same as that of the privacy grating on the conventional privacy film, which will not be described here, and can be selected according to actual needs. Preferably, the cover body 100 is a glass cover.

[0025] In addition, it should be noted that since the privacy film is attached to the surface of the product, the texture will give users a cheap feeling of plastic. The privacy film structure of the utility model has the privacy film on the back of the cover, and the front of the cover can be coated, such as anti-fouling and antibacterial coating, anti-scratch coating, etc. In this way, the thickness of the product can be reduced and the plastic feeling can be avoided.

[0026] In one embodiment, since the anti-peeping grating formed by the single-layer first black ink layer 210 is thin, its anti-peeping effect is poor. Therefore, in this embodiment, in order to further improve the anti-peeping effect, the anti-peeping element 200 further includes a second black ink layer 220 and a third black ink layer 230, and the anti-peeping grating is formed on the second black ink layer 220 and the third black ink layer 230, respectively, and the protective element 300 further includes a second protective layer 320 and a third protective layer 330, and the first black ink layer 210, the first protective layer 310, the second black ink layer 220, the second protective layer 320, the third black ink layer 230 and the third protective layer 330 are stacked in sequence in the direction away from the cover body 100. Among them, the first protective layer 310 and the second protective layer 320 sandwiched between the two black ink layers not only have the function of protecting the black ink layer from falling off, but also have the function of increasing the adhesion between the two black ink layers; in addition, they also have the function of increasing the thickness of the anti-peeping grating, so as to further improve the anti-peeping effect. In this embodiment, the stacked thickness of the privacy protection element 200 and the protective element 300 is 80-100 μm, that is, the total thickness of the first black ink layer 210, the first protective layer 310, the second black ink layer 220, the second protective layer 320, the third black ink layer 230 and the third protective layer 330 is 80-100 μm.

[0027] In another embodiment, similarly, since the anti-peeping grating formed by the single-layer first black ink layer 210 is thin, its anti-peeping effect is poor. The anti-peeping member 200 further includes a fourth black ink layer 240, on which an anti-peeping grating is formed, and the protective member 300 further includes a fourth protective layer 340, which is disposed on a side of the third protective layer 330 away from the second protective layer 320, and the fourth protective layer 340 covers the fourth black ink layer 240. That is, the first black ink layer 210, the first protective layer 310, the second black ink layer 220, the second protective layer 320, the third black ink layer 230, the third protective layer 330, the fourth black ink layer 240 and the fourth protective layer 340 are stacked in sequence in a direction away from the cover body 100. The first protective layer 310, the second protective layer 320 and the third protective layer 320 sandwiched between the two black ink layers not only protect the black ink layer from falling off, but also increase the adhesion between the two black ink layers. In addition, they also increase the thickness of the anti-peeping grating to further improve the anti-peeping effect. In this embodiment, the superimposed thickness of the anti-peeping piece 200 and the protective piece 300 is 80-100 μm, that is, the total thickness of the first black ink layer 210, the first protective layer 310, the second black ink layer 220, the second protective layer 320, the third black ink layer 230, and the third protective layer 330 is 80-100 μm.

[0028] Preferably, the first protective layer 310 is a first OC (Overcoat film, a cured film protective layer) protective film layer. The first OC protective film layer has high light transmittance, so while isolating and protecting the first black ink layer 220, it can also ensure the display effect of the display screen. In addition, the first OC protective film layer is entirely covered on the first black ink layer 220 by silk screen printing. Preferably, the thickness of the first OC protective film layer is 12-18μm, for example, the thickness of the first OC protective film layer is 15μm. In addition, the second protective layer 320, the third protective layer 330 and the fourth protective layer 340 all use OC protective film layers, and their thicknesses are all selected to be 12-18μm.

[0029] Preferably, the thickness of the first black ink layer 210 is 12-18 μm. For example, the thickness of the first black ink layer 210 is 15 μm.

[0030] Preferably, the thicknesses of the second black ink layer 220 , the third black ink layer 230 , and the fourth black ink layer 240 are 12-18 μm respectively.

[0031] A display screen includes the above-mentioned anti-peep cover structure 10.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
