Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

As shown in Figures 1 to 3, the utility model provides a magnetic screen film 100, which is adsorbed on an electronic device 30 of a screen 20 having a metal frame 10. The electronic device 30 referred to here includes, but is not limited to, mobile electronic products such as smart phones, tablet computers, and notebook computers.

The magnetic screen film 100 includes a magnetic tape 120 attached to any edge 112 of any side 110 of the magnetic screen film 100 . The magnetic tape 120 is adsorbed correspondingly to the metal frame 10 , and is correspondingly covered on the screen 20 .

In this embodiment, the magnetic tape 120 is preferably a commercially available double-sided tape containing magnetic powder, which is directly attached to the edge 112 of the screen film 100 and magnetically attracted to the metal frame 10 of the electronic device 30 . Users can magnetically attach or detach the screen film 100 to or from the screen 20 at any time as needed, which is quick, convenient, easy and low-cost to use. In addition, the magnetic tape 120 pasted on the screen film 100 has a certain degree of flexibility, so that the screen film 100 has the characteristics of bending and not easily deformed.

Due to the variety of commercially available magnet tape 120 (also known as rubber magnet), it can be selected from magnetic powder, metal powder, adhesive, PET, foam, non-woven fabric, release paper/film, silica gel and rubber. Various double-sided tapes, such as tissue double-sided tape, PET film double-sided tape, non-woven substrate double-sided tape, foam double-sided tape, etc.

The screen film 100 of this embodiment is preferably a privacy film. Generally speaking, the anti-spy sheet is composed of a resin layer, an adhesive layer, a grating layer, an adhesive layer, and a resin layer from top to bottom (the figure is omitted), and the grating layer (the figure is omitted) To provide a viewing range within a specific angle. Further, the grating layer (not shown) is composed of a plurality of opaque grating thin plates (not shown), for example, and is formed by adopting the principle of microlouver. When the grating thin plates are arranged in parallel and equidistant (that is, the vertical louver structure), the light can be limited to a specific angle, so that only a certain angle of visibility can be provided, for example, the viewing angle is at the frontal angle (ie, zero angle) , because the light is not blocked, so the visibility is not affected. On the contrary, if the angle deviation is larger, the brightness will be lower, so that the effects of anti-peeping and information security can be fully achieved.

Since the anti-peeping sheet will cause the brightness of the screen 20 to dim and reduce the sharpness of the picture, it will easily damage the vision of the human eye if used for a long time. In other words, when the user uses the above-mentioned electronic product 30 in a public place, the screen film 100 of this embodiment can be taken out and directly magnetically attached to the metal frame 10 of the electronic product 20, so as to avoid infringement of privacy; When the electronic product 30 is used or the eyes are tired, the screen diaphragm 100 can be quickly removed, so disassembly and installation are very convenient and fast, and there is no problem of damaging the screen 20 or the metal frame 10 .

In the embodiment shown in Figures 1 to 3, it is preferable to attach magnetic tapes 120 to the two side edges 112 of any side 110 to increase the magnetic adsorption force, thereby making the screen film 100 of this embodiment stable. is positioned on the metal frame 10 of the screen 20 .

In particular, as shown in FIG. 3 , a decoration layer 140 is also included, and the decoration layer 140 can be disposed on the opposite side of the magnetic tape 120 by coating or pasting, so as to increase the aesthetics. The material of the decoration layer 140 referred to here may be PET, PC film, Mylar film or other suitable materials, and is not limited.

Please also refer to FIG. 4, the magnetic tape 120 can also be attached to the corresponding two sides 110 of the screen film 100 at the same time, that is, the corresponding two sides 110 on the same edge 112, so as to increase the magnetism of the same edge 112. adsorption.

As shown in Figure 5, it also includes attaching or coating an adhesive layer 130 on any edge 112 of any side 110 of the screen film 100 in advance, and then attaching or coating the magnetic tape 120 on the adhesive layer 130. to strengthen the adhesive effect of the magnetic tape 120. The adhesive layer 130 in this embodiment, such as epoxy resin AB glue, double-sided tape, polyurethane adhesive, metal glue or other suitable adhesives, is not limited.

Since the magnetic tape 120 of the present invention is a commercially available double-sided adhesive tape containing magnetic powder, it can be directly attached to the screen diaphragm 100, that is, it can be magnetically adsorbed on the metal frame 10 of the electronic product 30. The novel screen diaphragm 100 is low in cost, quick and convenient to use and operate.

Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
