Description
Technical Field
The invention relates to the field of peep-proof films, in particular to a film cutting method of a peep-proof film.
Background
With the development of intelligent products such as mobile phones, notebook computers, tablets and the like, screen adhesive films thereof have become a huge market. People can paste a layer of peep-proof film on the surface of the screen in the using process, and the peep-proof, the falling-proof and the scratch-proof effects and the like of the screen are achieved.
The existing peep-proof film adopts a micro blind window technology, namely, the blind window principle is utilized, see fig. 1, the blind window is arranged in a film layer as a peep-proof structure layer, the wide visual angle of a screen is changed into a narrow visual angle through light angle control, and the wide visual angle is realized through a grating structure (the blind window) which is arranged in parallel, so that light in a certain angle cannot pass through the screen, the effect of the peep-proof screen is achieved, the display angle of the screen is reduced, people around you simply cannot see the content of the screen clearly, and the peep-proof film is named from the perspective. When light is vertically incident on the peep-proof film, the light can pass through the peep-proof film without obstruction. With the increase of the incident angle of the light, the light is gradually shielded by the shutter structure, and the transmitted light is reduced. Therefore, only a user facing the screen can receive enough light to see the screen clearly, and a bystander at a certain angle with the screen receives weaker light which looks like a piece of dark black, so that the peep-proof function is good, and the privacy protection function of the peep-proof device is welcomed by users all over the world.
For screens of intelligent products such as mobile phones, notebook computers, tablets and the like, due to the fact that the resolution of the screens is different from the polaroid of the display screen, the miniature display of the screens is not absolutely horizontal, and a certain rotation angle is presented. When the peep-proof membrane is attached to the screen, if the peep-proof membrane does not rotate by a corresponding angle, clear stripes can appear, the use of consumers is influenced, and the experience feeling is poor. The peep-proof films on the market are all made into specific models in advance, each peep-proof film of the specific model corresponds to different rotation angles, and the peep-proof films are not all suitable for intelligent products such as mobile phones, notebook computers and tablets which are not common or not national standard.
