Technical Field
The instant disclosure relates to a screen protection filter, and particularly relates to an attractive-type screen protection filter.
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.

DETAILED DESCRIPTION
The spirit and scope of the instant disclosure is further introduced by the way of example and in terms of the preferred embodiments as follows.
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 defined side-by-side to each other, wherein the attraction area 11 is defined at a lengthwise edge (the top edge in FIG. 1) of the protection filter body 10, adjacent to the top lengthwise side surface 111 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 front surface 13 and rear surface 14 of the protection filter body 10. In embodiments of the application, attracting member 20 comprises one or more attracting block(s) 21, wherein 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, outer surfaces of the attracting block(s) 21 are preferably aligned with the front and rear surfaces 13/14 of the protection filter body 10 to be more shipshape; however, the surfaces of the attracting block(s) 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. In some embodiments, the attraction component(s) 3 of the electronic device 2 may be implemented as a supporting frame fastened to a display panel of the display screen 4 for attaching to a housing of the electronic device 2; alternatively, the attraction component(s) may be an additional part of such supporting frame of the display screen 4. Whether implemented as the supporting frame or the additional part of the supporting frame, the attraction component(s) 3 may be magnets or ferromagnetic components so to be attractable by a magnetic force. In different embodiments, the position of the attraction component 3 varies, such as at the edges and/or the corners in the peripheral surrounding the display panel of the display screen 4, or adjacent to the edge of the display panel yet behind the display panel of the display screen 4. In an embodiment, 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 20, thereby achieving the advantages of rapidly attaching and removing. Furthermore, corresponding to a visual sensor 5 (such as a camera with CCD or CMOS components) 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 light(s), 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 long slot. The accommodation holes 12 are defined with symmetry according to a center line C1 of the protection filter body 10. Each of the attracting blocks 21 may be 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 is a perspective view of a screen protection filter according to a second exemplary embodiment of the instant disclosure, the difference between the second embodiment and the first embodiment is that, multiple attracting blocks 21 (here each attracting blocks 21 is circular or oval) are positioned at the attraction area 11 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. It is understood that the attracting block(s) 21 of the attracting member 20 of the application may have a variety of shapes and/or sizes in addition to those shown in the drawings. In addition, differently shaped and/or sized attracting blocks 21 may be used on a given protection filter body 10. Moreover, in embodiments of the application, the attracting block(s) 21 may be arranged on a given protection filter body 10 in locations other than those illustrated in the drawings.
Refer to FIG. 3, which is a sectional view of a protection filter body according to an exemplary embodiment of the instant disclosure. The protection filter body 10 includes two outer layers 101, 103 and a grating layer 102; however, in other embodiments of the application, the protection filter body 10 may include only one outer layer 101, or more that two outer layers 101. The outer layers 101, 103 may be highly transparent resin layers. For example, the outer layers 101, 103 may be Polyimide, Polyethylene terephthalate, Polycarbonate or PET. The grating layer 102 is disposed between the two outer layers 101, 103. For example, the outer layers 101, 103 are respectively adhered onto two opposite surfaces of the grating layer 102.
Refer to FIG. 4, which is a sectional view of a grating layer according to an exemplary embodiment of the instant disclosure. The grating layer 102 includes multiple opaque grating walls 1021 configured according to microlouver principle. The opaque grating walls 1021 of the grating layer 102 are configured in parallel with a constant interval (namely standing louver structures) to limit light passing within a certain angle α. Therefore, only a visual range within the angle α is provided; and the angle shown as Arrow V, vertical to the grating layer 102 (namely zero degree), can have unaffected visibility as most of light is not blocked. If the viewing angle differentiates more from the angle α, the brightness becomes lower, thereby sufficiently preventing nearby persons from spying and keeping privacy.
Refer to FIG. 6, which is a perspective view of a screen protection filter according to a third exemplary embodiment of the instant disclosure. The major difference between the embodiment and the first embodiment is, the protection filter body 10 further includes a shield piece 30 configured at the attraction area 11. For example, the shield piece 30 may be formed by heat compression molding to cover over the attraction area 11, as well as covering over the outer portions of the attracting block(s) 21 and of the accommodation hole(s) 12, as shown in FIG. 6B, thereby protecting the attracting block(s) 21 and beautifying the appearance. It is understood that the shield piece may cover either both the front and rear surfaces 13/14 or just the front surface 13 or rear surface 14 of the protection filter body 10. The shield piece 30 may be a plastic piece made of PU, PC, PMMA, PE, PVC or PET to achieve dirt-proof, water-repellent and abrasion-resistant effects; alternatively, the shield piece 30 may be a piece made of rubber, silicon, leather or cloth materials, which may be transparent, translucent or opaque. In another embodiments, the shield piece 30 may be formed by printing an ink layer consisting of known ink solutions, or any materials mentioned in the examples introduced within the instant disclosure made as ink solutions.
As shown in FIGS. 6, 6A and 6B, in an embodiment of the application, a through hole 31 is further defined on the shield piece 30. Please jointly refer to FIG. 2, the through hole 31 is defined corresponding to the opening 17 of the protection filter body 10 and the visual sensor 5 of the electronic device 2, so as to prevent the visual sensor 5 from being covered by the shield piece 30 when the screen protection filter 1 is attached onto the electronic device 2. The shield piece 30 may cover the inner wall of the opening 17, as shown in FIG. 7. Alternatively, the shield piece 30 may not cover the inner wall of the opening 17 and leave the inner wall of the opening 17 exposed, as shown in FIGS. 6 and 6A. In the embodiment of FIGS. 6, 6A and 6B, the top lengthwise side surface 111 of the protection filter body 10 is covered by the shield piece 30. Refer to FIG. 6C, which illustrates a partial sectional view, corresponding to Line B-B′ in FIG. 6 of another embodiment of the instant disclosure in which two shield pieces 30 are provided, one on the front surface 12 and another on the rear surface 14, leaving the top lengthwise side surface 111 of the protection filter body 10 exposed. It is noted that when the screen protection filter 1 is attached to the electronic device 2, the shield piece 30 can provide buffering effect there between. In some embodiments, other openings or holes may be further defined in the shield piece(s) 30 to correspond to other functional components of electronic device 2 (such as light(s), earphone jack(s) or functional button(s)), which are not illustrated in the drawings.
Refer to FIG. 7, which is a perspective view of a screen protection filter according to a fourth exemplary embodiment of the instant disclosure. A difference between the embodiment and the third embodiment is that a pulling piece 16 is extended at an edge of the protection filter body 10, so that after the screen protection filter 1 is attached to the electronic device 2, the pulling piece 16 protrudes from a side of the electronic device 2. When the user has the need to remove the screen protection filter 1, the pulling piece 16 may be held by the user and applied with outward force to remove the screen protection filter 1 from the electronic device 2. Additionally, the pulling piece 16 and the protection filter body 10 in some embodiments may be formed in one piece to achieve better structural strength and faster manufacturing art.
Refer to FIG. 8, which is a perspective view of a screen protection filter according to a fifth exemplary embodiment of the instant disclosure. In the embodiment, the electronic device 2 is a tablet computer, and the attraction area 11′ of the screen protection filter 1 is defined along the peripheral of the protection filter body 10. The accommodation holes 12 are defined at all four edges of the protection filter body 10, and each of the accommodation holes 12 has an attracting block 21 positioned therein, corresponding to the attraction components 3 configured inside the electronic device 2. Preferably, these accommodation holes 12 and attracting blocks 21 are defined with symmetry according to a center line C2 of the protection filter body 10 to achieve better attaching effect. In another embodiments, the accommodation hole 12 and the attracting block 21 positioned therein may be disposed at just one lengthwise edge, or one widthwise edge, or two opposite lengthwise edges, or two opposite widthwise edges, or even three adjacent edges of the protection filter body 10. In other words, one or multiple edges of the protection filter body 10 are capable of attaching to the attraction component 3 of the electronic device 2.
Refer to FIG. 9, which is a perspective view of a screen protection filter according to a sixth exemplary embodiment of the instant disclosure. In the embodiment, the accommodation hole 12 is omitted on the screen protection filter 1, and the attracting member 20 is disposed directly on the front surface 13 of the protection filter body 10 in the attraction area 11. For example, the attracting member 20 may be positioned on the surface 13 of the protection filter body 10 in the attraction area 11 by adhering or heat compression. In this embodiment, the attracting member 20 includes multiple attracting blocks 21, which are disposed with symmetry according to the center line C1 of the protection filter body 10. Alternatively, as shown in FIG. 10, the attracting member 20 may comprise a single, long bar-shaped attracting block 21 and cover most of the attraction area 11, with an opening 201 of the attracting block 21 corresponding to the opening 17 of the protection filter body 10. Namely, the attracting block 21 may be disposed at a lengthwise edge of the protection filter body 10, adjacent to the lengthwise side surface 111 of the lengthwise edge of the protection filter body 10. In another embodiment, the attracting member 20 may have exactly the same shape and size as the attraction area 11, covering over the entire attraction area 11. In embodiments of the application, the outer portion(s) of the attracting member(s) 20 in either FIG. 9 or FIG. 10 may also be covered by one or more shield pieces 30, as shown in FIGS. 6, 6A, 6B, 6C and 10A. In different embodiments, one or more shield pieces 30 is configured to cover portions of one or both of the front and rear surfaces 13/14 in the attraction area 11, and on outer surfaces of the attracting block(s) 21. In addition, the shield piece 30 may cover over the entire side surface 111 of the protection filter body 10 in the attraction area 11, or only some of the side surface 111 of the protection filter body 10 in the attraction area 11. In embodiments of the application, the shield piece(s) 30 may, for example, cover one or both of the front and rear surfaces 13/14 of the protection filter body 10 (in the location of the attraction area 11), with the attracting block(s) 21 disposed between a shield piece 30 and the protection filter body 10 or disposed within the protection filter body 10. Moreover, in some embodiments of the application, one or more of the side surface(s) of the protection filter body 10 may covered by the shield piece 30, while in other embodiments of the application the side surface(s) of the protection filter body 10 may be exposed. It is also noted that while center lines C1, C2 have been disclosed in FIG. 1, FIG. 5, FIG. 8, FIG. 9 and in several paragraphs in Detailed Description to illustrate symmetrical positioning of the accommodation holes 12, in other embodiments of the application, the positioning of the attracting blocks 21 is not symmetrical. This is particularly useful in embodiments for which the attraction components 3 of the electronic device 2 on which the protection filter body 10 will be disposed do not have a symmetrical arrangement.
With reference to FIGS. 11, 12, 13, in additional embodiments of the application, an attracting member 20 comprising one or more attracting blocks 21 may be disposed at just one lengthwise edge (FIG. 11) or one widthwise edge (not shown), or two opposite lengthwise edges (FIG. 12) or two opposite widthwise edges (not shown), or all four edges (FIG. 13), or even three edges (not shown) of the protection filter body 10. Similarly, one or more shield pieces 30 may be disposed on the front and/or rear surfaces 13/14 of the protection filter body 10 covering the attracting blocks 21. Thus, in embodiments of the application, one or multiple edges of the protection filter body 10 may be configured to attach to the attraction component 3 of the electronic device 2 by magnetic forces. Moreover, in any of the above-mentioned embodiments, examples and drawings, a notch 32 of at least one shield piece 30, as well as the corresponding opening 17 of the protection filter body 10 and the corresponding opening 201 of the attracting block 21 may all be defined as recesses of the same or similar shape. Therefore, when the screen protection filter 1 is removably attached to the display screen 4 of different electronic devices 2, the notch(es) 32 of the shield piece(s) 30, the corresponding opening 17 of the protection filter body 10 and the corresponding opening 201 of the attracting member 20 are arranged to expose and otherwise avoid interference with the functionality of a variety of the electronic devices 2, namely to avoid covering various sizes, shapes, positions and/or number of functional component(s) (such as visual sensors 5, light(s), earphone jack(s) or functional button(s)) of different electronic devices 2. In embodiments of the application, shapes of the notch(es) 32 of the shield piece(s) 30, the corresponding opening 17 of the protection filter body 10 and the corresponding opening 201 of the attracting member 21 may be trapezoid or rectangular.
In FIGS. 11, 12, 13, the attracting blocks 21 may comprise lengthy, thin, magnetic/ferromagnetic sheets or metallic sheet/band/papers disposed at one or more corresponding edges (one lengthwise edge in FIG. 11; two opposite lengthwise edges in FIG. 12; and four edges in FIG. 13) of privacy filter body 10 disposed in attraction area(s) 11. The attracting blocks 21 may cover an entire edge or edges of the protection filter body 10, as illustrated in FIGS. 11 and 12, or there may be an exposed rim of the front surface 13 exposed by the attracting block 21, as illustrated in FIG. 10. The attracting block(s) 21 may cover the front and/or rear surfaces of the protection filter body 10 in the attraction area 11. The shield piece(s) 30 may, accordingly, cover the attracting block(s) 21. In some embodiments of the application, the attracting blocks 21 may be disposed at three edges of the protection filter body 10. In FIGS. 11, 12 and FIG. 13, the side surface 111 of the protection filter body 10 in the attraction area 11 (at the lengthwise/widthwise edge or the corners) of the protection filter body 10 may be exposed without being covered by the shield piece(s) 30. Alternatively, in other embodiments, the side surface 111 of the protection filter body 10 may be covered by the shield piece(s) 30, similar to the full coverage of the shield piece 30 illustrated in FIG. 6 and FIG. 7. In another embodiments, the shield piece(s) 30 and/or the attracting block(s) 21 configured at the rear surface of the protection filter body 10 in FIGS. 11, 12, 13 may be omitted.
Refer to FIGS. 14, 15, 16, 17, 18, 19 and FIG. 20. In these embodiments, attracting block(s) 21 with various sizes/shapes/quantity may be disposed at one or more corners of the protection filter body 10 of the screen protection filter. Moreover, corresponding shield piece(s) 30 may directly cover the attracting block(s) 21. FIG. 14 is a perspective view of a screen protection filter 1 according to another exemplary embodiment of the instant disclosure. In FIG. 14, shield pieces 30 and attracting blocks 21 that are triangular and configured to cover each of the right and left bottom corners of the protection filter body 10 are provided. In embodiments of the application, the shield pieces 30 disposed at corners of the protection filter body 10 extend directly adjacent to the side surfaces of the protection filter body 10 at both of the edges that define the corner. The shield pieces 30 and the attracting blocks 21 at each of the right and left bottom corners of the protection filter body 10, or alternately just the shield pieces 30, may be triangular. As shown in FIG. 14 to FIG. 18, since the lower two shield pieces 30 in the drawing are at corners of the protection filter body 10, the length of each of the shield pieces 30 at the corners along each of the edges of the protection filter body 10 that define the corner is less than the entire length of each of the edges of the protection filter body 10 that define the corner. In FIG. 14, attracting blocks 21 and the shield pieces 30 are configured at both front and rear surfaces 13/14 of the protection filter body 10. The corner portion of the protection filter body 10 configured with shield pieces 30 and/or the attracting blocks 21 may also be defined as portions of the attraction area 11 mentioned previously. In FIG. 14, there two are attracting blocks 21 and two shield pieces 30 extending along a lengthwise edge of the protection filter body 10 and disposed adjacent to a side surface 111 of the lengthwise (top) edge of the protection filter body 10, but having a gap there between corresponding to the location of opening 17. FIG. 15 is a front view of a screen protection filter 1 according to another exemplary embodiment of the instant disclosure. Similar to FIG. 14, in FIG. 15, two triangular shield pieces 30 are configured at the right and left corners of the protection filter body 10, with the attracting blocks 21 also being configured at the corners. However, in this embodiment, there is no shield pieces 30 or attracting blocks 21 on the rear surface 14 of the protection filter body 10. FIG. 16 is a front view of a screen protection filter 1 according to another exemplary embodiment of the instant disclosure. Similar to FIG. 14 and FIG. 15, in FIG. 16, the shield pieces 30 and the attracting blocks 21 are configured at the right/left bottom corners at the rear surface 14 of the protection filter body 10, but with no shield pieces 30 or attracting blocks 21 on the front surface 13 of the protection filter body 10. FIG. 17 is a side view of the screen protection filter 1 of an embodiment of the application illustrated in FIG. 14, wherein the shield pieces 30 do not cover the side surfaces of the protection filter body 10. FIG. 18 is the side view of the screen protection filter 1 of an embodiment of the application illustrated in FIG. 16, again in which the shield pieces 30 do not cover the side surfaces of the protection filter body 10. FIG. 19 and FIG. 20 are respectively top and bottom views of a screen protection filter 1 of an embodiment of the screen protection filter 1 in FIG. 14.
