Detailed Description
To further illustrate the technical means and effects of the present invention, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings.
Referring to fig. 1, the present invention provides a display screen protective film, which includes a substrate layer 10, a semitransparent pattern layer 20 and a protective layer 30 sequentially disposed. One side of the translucent pattern layer 20 is provided with a translucent pattern 21.
Specifically, referring to fig. 1, the display screen protective film further includes an oleophobic layer 40 disposed on a side of the protective layer 30 away from the translucent pattern layer 20, where the oleophobic layer can prevent fingerprints and dirt from remaining on the surface of the display screen protective film when the display screen protective film is used, and increase the smoothness of the surface of the display screen protective film, so that the display screen protective film has a better touch operation effect.
Preferably, referring to fig. 1, the oil-repellent layer 40 covers the peripheral edges of the substrate layer 10, the translucent pattern layer 20 and the protective layer 30.
Further, referring to fig. 1, the display screen protective film further includes a hardening layer 50 disposed between the oil-repellent layer 40 and the protective layer 30 for enhancing the hardness of the display screen protective film as a whole.
Specifically, the side of the protection layer 30 away from the translucent pattern layer 20 may be a plane or a curved surface, and in the embodiment shown in fig. 1, the side of the protection layer 30 away from the translucent pattern layer 20 is a plane.
Specifically, referring to fig. 1, the display screen protective film further includes an optical adhesive layer 60 disposed between the translucent pattern layer 20 and the substrate layer 10, a transparent silicone layer 70 disposed on a side of the substrate layer 10 away from the translucent pattern layer 20, and a release film 80 disposed on a side of the transparent silicone layer 70 away from the substrate layer 10. This optical adhesive layer 60 is used for bonding substrate layer 10 and translucent pattern layer 20, and transparent silica gel layer 70 is used for pasting with the surface of display screen when display screen protection film uses to have the automatic exhaust function that adsorbs, should be used for protecting transparent silica gel layer 70 from type membrane 80, need tear this from type membrane 80 during the use, from type membrane 80 can have the colour, also can print the pattern.
Specifically, the material of the protective layer 30 is tempered glass, polyethylene terephthalate (PET), thermoplastic polyurethane elastomer (TPU), or other materials commonly used in the prior art as a film layer having a protective function in a display screen protective film.
Specifically, the material of the substrate layer 10 is PET or TPU. Further, the substrate layer 10 may be manufactured by using the prior art as a substrate layer having a blue light resisting function, a substrate layer having an anti-peeping function (for example, the content displayed through the display screen protective film cannot be seen clearly when the viewing angle is deviated by more than 30 degrees from the front viewing angle), and a substrate layer having a mirror surface function, and the substrate layer 10 may be transparent or may be colored in a translucent manner.
Specifically, the translucent pattern 21 is made by screen printing, laser engraving, printing, plating, or etching sanding process.
Further, the specific manufacturing method of the translucent pattern 21 is as follows: the translucent pattern 21 is formed by screen printing, laser engraving, printing, electroplating or etching and frosting on one side of a substrate made of tempered glass, PET, TPU or other materials commonly used in the prior art as a film layer having a protective function in a display screen protective film, so as to form a translucent pattern layer 20 having the translucent pattern 21 on one side.
Specifically, referring to fig. 1, the semitransparent pattern layer 20 includes a window area 22 and a frame area 23 located outside the window area 22. The translucent pattern 21 is located in the window area 22. The portion of the translucent pattern layer 20 in the border area 23 has a color, and the portion of the translucent pattern layer 20 in the window area 22 has a color or is colorless.
Referring to fig. 2 and 3, after the display screen protective film 1 of the present invention is attached to the display screen 9, as shown in fig. 2, when the display screen 9 performs normal display, light emitted from the display screen 9 can pass through the translucent pattern 21 in the translucent pattern layer 20, and the translucent pattern 21 can not block the light emitted from the display screen 9, so that after the light passing through the display screen protective film 1 is incident on human eyes, a user can not observe the translucent pattern 21, and thus the normal display of the display screen 9 is not affected, as shown in fig. 3, when the display screen 9 is in an off state, the translucent pattern 21 can reflect external light to be absorbed into human eyes, so that a contrast is formed between a region where the translucent pattern 21 is located and other regions, so that the user can view corresponding patterns, and thus the existence of the translucent pattern 21 can display contents when the display screen 9 is in the off state, therefore, the function of the display screen protective film is increased, the aesthetic property of the display screen protective film is improved, in addition, when the semitransparent pattern 21 is manufactured by adopting an electroplating process, the semitransparent pattern 21 can generate a mirror surface effect when the display screen 9 is in an off state so as to be used as a mirror, and the function of the display screen protective film is further increased.
In summary, the display screen protective film of the invention includes the substrate layer, the semitransparent pattern layer and the protective layer which are sequentially arranged, and one side of the semitransparent pattern layer is provided with the semitransparent pattern. The display screen protective film disclosed by the invention is attached to the surface of the display screen when in use, light emitted by the display screen is emitted into eyes of a user through the display screen protective film when the display screen normally displays, so that the display effect of the screen cannot be influenced, and when the display screen is in an off state, external light is reflected into the eyes of the user through the semitransparent patterns, so that the user can watch the corresponding patterns, and the display screen protective film has multiple functions and high attractiveness.
As described above, it will be apparent to those skilled in the art that other various changes and modifications may be made based on the technical solution and concept of the present invention, and all such changes and modifications are intended to fall within the scope of the appended claims.
