Related Art
With the advanced progresses of technologies and networks, mobile devices (such as smartphones, tablet computers, notebook computers, etc.) have become indispensable for daily human life. Since mobile devices are very convenient to carry with, people use mobile devices in the offices, in public facilities or on public transportation vehicles.
Generally, mobile devices available in the market mostly do not have the function of preventing the screen from spying. While using in public, nearby persons can easily see the contents displayed on the screen, so user privacy cannot be protected. Accordingly, one solution is to adhere a privacy sheet on the screen of the mobile device to prevent from being easily viewed. However, users find it difficult to remove the privacy sheet adhered on the screen, and the residual glue is even more troublesome. While using in private space, without the concerns of privacy protection temporarily, the privacy sheet adhered on the screen still cannot be easily removed. If the privacy sheet is kept adhered on the screen, it generally causes the brightness of the screen to be darker and the sharpness of the screen to be lower, which will harm the user's eyesight in the long term. Therefore, improvements are necessary.

Please refer to FIG. 1, which illustrates an exploded perspective view of a screen protection filter according to a first exemplary embodiment of the instant disclosure. In the embodiment, a screen protection filter 1 includes a protection filter body 10 and an attracting member 20. The protection filter body 10 includes an attraction area 11 and a protection area 15, wherein the attraction area 11 is defined at a side of the protection filter body 10, and the protection area 15 includes the rest of the protection filter body 10 other than the attraction area 11. Accommodation hole(s) 12 are defined within the attraction area 11 of the protection filter body 10, and each accommodation hole 12 intercommunicates the two opposite surfaces of the protection filter body 10. The attracting member 20 includes attracting block(s) 21, and each attracting block 21 is positioned in the accommodation hole 12 by inserting or adhering the attracting block 21 inside the accommodation hole 12. In an embodiment, the surfaces of the attracting block 21 is preferably aligning with the surfaces of the protection filter body 10 to be more shipshape; however, the surfaces of the attracting block 21 may be adapted higher or lower than the surface of the protection filter body 10, which is not limited to the embodiment.
Accordingly, as shown in FIG. 2, by disposing the attracting member 20 at the attraction area 11 of the protection filter body 10, the protection filter body 10 with the attracting member 20 is attachable correspondingly to the attraction components 3 of the electronic device 2. The attracting member 20 and the attraction component 3 may both be magnets (for example Ferrite, alnico or rare-earth magnet) with different magnetic poles, or alternatively one of the attracting member 20 and the attraction component 3 may be a magnet and the other may be a ferromagnetic component (for example Fe, Ni, Co, or any metal components attractable to magnetic force), such that the attracting member 20 and the attraction component 3 may be attracted to each other. If the attracting member 20 and the attraction component 3 are magnets with different magnetic poles respectively, the attracting member 20 is attracted by the magnetic force to automatically align with the attraction component 3, thereby automatically positioning the screen protection filter 1 onto a correct position on the display screen 4 of the electronic device 2. In the embodiment, the electronic device 2 is a notebook computer, and the attraction components 3 are configured inside the notebook computer at the top portion of the display screen 4 for the attracting member 20 of the protection filter body 10 to correspondingly attach thereto. When the protection filter body 10 is moved with its attracting member 20 close to the attraction components 3, the magnetic force functions and make the attracting member 20 attach on the attraction components 3. The screen protection filter 1 is consequently positioned on the electronic device 2, with the protection area 15 of the protection filter body 10 correspondingly covering over the display screen 4 of the electronic device 2, thereby preventing nearby persons from spying privacy contents on the display screen 4. In addition, when the user has a need to remove the screen protection filter 1, the user needs only to remove the attracting member 20 from the attraction component of the electronic device 23, thereby achieving the advantages of rapidly attaching and removing. Furthermore, corresponding to a visual sensor 5 of the electronic device 2, an opening 17 is defined within the attraction area 11 of the protection filter body 10, thereby preventing the visual sensor 5 from being covered by the protection filter body 10 when the screen protection filter 1 is attached to the electronic device 2. Certainly, if necessary, other openings or holes may be defined on the protection filter body 10 to correspond to any other function components of the electronic device 2 (such as earphone jack(s) or functional button(s)).
Moreover, as shown in FIG. 1, in the embodiment, two accommodation holes 12 are defined within the attraction area 11 of the protection filter body 10. Each of the accommodation holes 12 is a slot. The accommodation holes 12 are defined with symmetry according to a center line C1 of the protection filter body 10. And each of the attracting blocks 21 may be long bar-shaped, corresponding to the shape of the accommodation hole 12, to have a greater attracting area. In addition, the attracting blocks 21 respectively positioned in each of the accommodation holes 12 are also positioned with symmetry according to the center line C1 of the protection filter body 10. Therefore, the attraction area 11 of the protection filter body 10 is able to averagely attach to the electronic device 2 and achieve better positioning. In some embodiments, the attraction area 11 of the protection filter body 10 may define only one accommodation hole 12, which is not a limitation to the embodiment. Besides, as shown in FIG. 5, which a perspective view of a screen protection filter according to a second exemplary embodiment of the instant disclosure, the difference between the embodiment and the first embodiment is that, multiple attracting blocks 21 (here each attracting blocks 21 is circular) are positioned at the attraction area 11 and at both sides of the center line C1 of the protection filter body 10, so as to have multiple attaching points and enhance the positioning effect.
