This disclosure proposes a protective film, which is easy to remove during the panel assembly process, which improves the efficiency of the manufacturing process and reduces damage to the product. The first description of the protective film in this disclosure will be described with reference to FIGS. 1A and 1B. Embodiments.

Please refer to FIG. 1A first, which illustrates a schematic top view of a protective film 100A according to an embodiment of the present disclosure. As shown in FIG. 1A, the protective film 100A includes an inner film 110 and an outer film 120. The inner membrane 110 has a main body portion 111 and a lug portion 112, and the lug portion 112 extends from the first side edge 111 a of the main body portion 111. There is a folding line 113 between the lug portion 112 and the main body portion 111, and the folding line 113 is connected to the first side edge 111 a of the main body portion 111. The outer film 120 and the lug portion 112 surround the main body portion 111 together. The outer membrane 120 and the lug portion 112 are connected by a connecting section 130.

In this embodiment, the protective film 100A has a rectangular shape as a whole, but in different applications, those skilled in the art can change the shape of the protective film 100A according to practical requirements, and the disclosure is not limited to the above.

As shown in FIG. 1A, the inner membrane 110 has a main body portion 111 and a lug portion 112. The main body portion 111 is substantially rectangular, but the first side edge 111a and the second side edge 111b of the main body portion 111 are inclined. The folding line 113 is connected, that is, there is a chamfer between the first side edge 111a and the second side edge 111b, and the lug portion 112 extends from the chamfer. That is, the lug portion 112 extends from the fold line 113 and is connected to the first side edge 111 a and the second side edge 111 b of the main body portion 111.

In this embodiment, since the lug portion 112 is disposed at a position adjacent to the corner of the main body portion 111, the user can more easily remove the inner film 110 of the protective film 100A by pulling the lug portion 112. However, a person skilled in the art may change the setting position of the lug portion 112 according to practical requirements, and the disclosure is not limited to the above. For example, in some embodiments, the main body portion 111 is rectangular, or the lug portion 112 is located closer to the center of the first side edge 111a or the center of the second side edge 111b.

In the embodiment of FIG. 1A, one lug edge 112 a of the lug portion 112 actually cuts the second side edge 111 b of the main body portion 111. That is, both the lug edge 112a and the second side edge 111b form a straight line. With the above design, the lug edge 112a and the second side edge 111b can be easily cut at the same time when the protective film 100A is manufactured, thereby simplifying the manufacturing process of the protective film 100A.

The fold line 113 is connected to the first side edge 111 a and the second side edge 111 b. The fold line 113 may be designed to be easily folded. For example, the fold line 113 may be a dashed line, an indentation line, and the like. By providing a folding line 113 between the lug portion 112 and the main body portion 111, the lug portion 112 can be folded along the folding line 113.

In the embodiment of FIG. 1A, an angle a is included between the folding line 113 and the first side edge 111 a. The included angle a is not equal to 0 degrees or 180 degrees. That is, the fold line 113 is not parallel to the first side edge 111a, and the fold line 113 and the first side edge 111a do not form a straight line. By designing the included angle a between the folding line 113 and the first side edge 111a, the user can easily fold and pull up the lug portion 112, and can ensure that the folded lug portion 112 is located in the main body portion 111. It should be understood that those skilled in the art can adjust the angle a according to practical needs.

As shown in FIG. 1A, the outer film 120 surrounds the main body portion 111 together with the lug portion 112. In the embodiment of FIG. 1A, the outer film 120 is completely disconnected from the main body portion 111, and the outer film 120 and the lug portion 112 are connected to each other by a connecting section 130. That is, the outer film 120 and the inner film 110 are connected to each other only by the connecting section 130. It should be understood that the position of the connecting section 130 is indicated by a dashed line in FIG. 1A, and the dotted line only represents the position of the connecting section 130 and does not indicate that the connecting section 130 has a structure of riding a stitch or a cutter. With the above design, the user is removing the film At 120, it will not affect the main body portion 111 of the inner membrane 110, so that the main body portion 111 can remain on the covered area; and when the outer membrane 120 is completely separated from the main body portion 111, the outer membrane will be pulled up by the connecting section 130 together The size of the lug portion 112 of the 120 and the connecting portion 130 can be designed to be easily torn off by human to separate the outer membrane 120 and the inner membrane 110. For example, the size of the connecting section 130 may be, for example, about 1 mm. Those skilled in the art can change the size of the connecting section 130 according to practical requirements.

The connecting section 130 is located on a side of the lug portion 112 opposite to the lug edge 112a. In this embodiment, by setting the connecting section 130 at a position where the lug section 112 is far from the fold line 113, when the outer film 120 is completely removed from the main body section 111 by removing the outer film 120, the connecting section 130 is pulled by the connecting section 130. When the lug portion 112 of the outer film 120 is further folded, the lug portion 112 can generate a large moment, so that the user can easily fold the lug portion 112 at the same time.

Please refer to FIG. 1B next, which shows a schematic plan view of the outer film 120 in FIG. 1A after the outer film 120 is removed and the lug portion 112 is folded based on the fold line 113. In FIG. 1B, the outer film 120 has been completely removed from the protective film 100A (the outer film 120 is therefore not shown in FIG. 1B), and the connecting section 130 connecting the outer film 120 and the lug portion 112 has been disconnected .

As shown in FIG. 1B, the lug portion 112 can be symmetrical about the coverage area A1 with the fold line 113 as an axis. The entire coverage area A1 is located in the main body portion 111 of the inner membrane 110. That is, the folded lug portion 112 is located in the main body portion 111 and covers the coverage area A1. With the above settings. The folded lug portion 112 may be completely located in the main body portion 111 of the inner membrane 110. In this way, while the starting point of the tearing is reserved, the work to be performed in the area other than the main body portion 111 of the inner membrane 110 is not affected.

In some embodiments, such as a narrow-frame panel structure, if the outer film 120 as a whole does not have a sufficient width (for example, less than 5 mm), the area of the lug portion 112 will not be sufficient for the user to hold. . Therefore, a protective film according to another embodiment of the present disclosure is used to solve the above-mentioned problem of insufficient width, which will be described below with reference to FIGS. 1C and 1D.

FIG. 1C is a schematic top view of a protective film 100B according to an embodiment of the disclosure. The difference between the protective film 100B and the protective film 100A is that the lug portion 112 of the protective film 100B further includes a body region 112b and a holding region 112c. It should be understood that, in FIG. 1C, the dotted line between the body region 112b and the gripping region 112c only represents the boundary between the two, and does not indicate that there is a structure of riding stitches or a cutter there. As shown in FIG. 1B, the main body region 112 b is connected to the main body portion 111, and the holding region 112 c is connected to the connection section 130. In other words, the lug portion 112 of the protective film 100A in FIG. 1A extends along the direction of the first side edge 111 a from the holding region 112 c in FIG. 1B. The lug portion 112 of the protective film 100B has a larger area than the protective film 100A. Therefore, in an embodiment in which the overall width of the outer film 120 is relatively narrow, the protective film 100B may be used to maintain a sufficient area of the ear portion 112.

Next, please refer to FIG. 1D, which shows a schematic plan view of the outer film 120 in FIG. 1C after the outer film 120 is removed and the lug portion 112 is folded based on the fold line 113. In FIG. 1D, the outer film 120 has been completely removed from the protective film 100B (hence the outer film 120 is not shown in FIG. 1D), and the connecting section 130 connecting the outer film 120 and the lug portion 112 has been disconnected .

As shown in FIG. 1D, the covering area A2 of the lug portion 112 of the protective film 100B with the fold line 113 as the axis mirror image is located in the region of the main body portion 111. In other words, the grip region 112c extending from the body region 112b is folded along The line 113 is located in the region of the main body portion 111 after the axis is mirror-symmetrical. In this way, the overall area of the lug portion 112 is increased without affecting the work to be performed in areas other than the main body portion 111 of the inner membrane 110.

The embodiments of the protective film 100A and the protective film 100B in the present disclosure have been described above from FIGS. 1A to 1D. The use of the protective film 100A and the protective film 100B in specific applications will be described below with reference to FIGS. 2 and 3A to 3D. The protective film provided in this disclosure, such as the protective film 100A, can be attached to the surface of the panel 300, and the protective film 100A can be torn off in sections to continuously protect the panel 300 during different stages of transportation or assembly.

FIG. 2 is a flowchart of a protective film removing method 200 according to an embodiment of the disclosure. 3A to 3D are three-dimensional schematic diagrams of the protective film removing method 200 in each stage in FIG. 2.

Please refer to Figure 2 and Figures 3A to 3C. The protective film removing method 200 starts from step S210. In step S210, the outer film 120 of the protective film 100A on the panel 300 is lifted, the outer film 120 is separated from the main body portion 111, and the lug portion 112 of the inner film 110 is pulled up by the connecting section 130. The outer membrane 120 can be lifted by the part adjacent to the lug edge 112a, because the lug edge 112a is relative to the connection section 130, it will not be pulled to the connection section 130 until the outer film 120 is fully lifted along the periphery of the main body 111, and The lug portion 112 is pulled up.

The protective film removing method 200 then proceeds to step S220. In step S220, the connection section 130 is disconnected. Specifically, the connecting section 130 can be torn open by hand. In some embodiments, the connecting segment 130 can also be disconnected by a cutting tool. After the connection section 130 is disconnected, the outer membrane 120 (which has been removed in FIG. 3B and is not shown) is completely separated from the inner membrane 110. After performing step S220, the outer membrane 120 has been completely separated from the inner film 110 and removed from the protective film 100A. At the same time, the inner film 110 is still covering the panel 300.

Next, step S230 is performed to fold the lug portion 112 along the fold line 113 so that the lug portion 112 and the main body portion 111 overlap.

Please refer to FIG. 2, FIG. 3D and FIG. 4, wherein FIG. 4 is a schematic plan view of the panel structure 500 in FIG. 3D. Next, step S240 is performed to cover the outer frame 400 on the peripheral region S1 of the panel 300. Due to the included angle a between the fold line 113 and the first side edge 111a, the two sides connected to the fold line 113 after the fold back lug portion 112 will not be completely covered by the outer frame 400, especially in the above-mentioned two sides away from the fold A portion of the fold line 113, that is, the folded lug portion 112 may be partially not covered by the outer frame 400. For example, the peripheral area S1 covered by the outer frame 400 is a non-display area of the panel 300, such as including the area of the panel 300 that is not covered by the main body portion 111 and the outer edge portion of the main body portion 111. In FIG. 4, a portion covered by the outer frame 400 (that is, the peripheral region S1) is indicated by diagonal lines, and the outline of the main body portion 111 is indicated by a dotted line.

As shown in FIG. 3D and FIG. 4, after step S240 is performed, the panel structure 500 includes the panel 300, the inner film 110 of the protective film 100A, and the outer frame 400. The inner film 110 is attached to the panel 300, and the inner film 110 has a main body portion 111 and a lug portion 112. The main body portion 111 and the lug portion 112 are connected by a fold line 113 and the lug portion 112 overlaps the main body portion 111. Specifically, the structure shown in FIG. 1B plus the outer frame 400 is the structure shown in FIG. 4.

As shown in FIGS. 3D and 4, the fold line 113 is located in the peripheral region S1. That is, the outer frame 400 covers the fold line 113. In the embodiment of the panel structure 500, by completely covering the folding line 113 with the outer frame 400, it is possible to Avoid part of the panel 300 from contacting the external environment. The outer frame 400 also covers the peripheral area S2 of the main body portion 111, so that it is more ensured that external impurities cannot touch the panel 300 located under the outer frame 400 or the inner film 110. In the embodiment of FIG. 4, the width of the peripheral region S2 is 0 to 0.5 mm.

After the outer film 120 (see FIG. 3A) is removed, the main body portion 111 remains on the panel 300. Therefore, the panel 300 can be protected by the outer frame 400 and the inner film 110 during the transportation process. Compared with the traditional process of completely removing the protective film, assembling the outer frame, and then pasting another protective film, this embodiment can effectively simplify the manufacturing process and reduce the cost.

Please continue to refer to Figure 2 and Figure 3D. Then, step S250 is performed to pull the lug portion 112 to remove the inner film 110 from the panel 300. Since the lug portion 112 is reserved in the area of the main body portion 111, the user can easily remove the inner membrane 110. In other words, the folded lug portion 112 reserves a starting point for removal, so that the user can easily remove the inner membrane 110.

Please refer to FIG. 5, which illustrates a cross-sectional view of the panel structure 500 along the line segment 5-5 in FIG. 4. As shown in FIG. 5, a part of the lug portion 112 is located between the outer frame 400 and the main body portion 111. With the above arrangement, when the user pulls the lug portion 112, the user will only rub the surface of the main body portion 111 away from the panel 300 without affecting the panel 300, and effectively reduce the damage that may be caused during the tearing of the inner film 110.

Please refer to FIG. 6, which illustrates a schematic top view of a panel structure 600 according to another embodiment of the present disclosure. The difference between the panel structure 600 in FIG. 6 and the panel structure 500 in FIG. 4 is the design of the lug portion 112. As shown in FIG. 6, the lug portion 112 includes a body region 112 b and a grip region 112 c. That is, Figure 4 The lug portion 112 in the middle extends a section of the gripping region 112c along the direction of the first side edge 111a, which becomes the structure shown in FIG. In this embodiment, at least part of the holding area 112c is not covered by the outer frame 400, that is, the sides of the holding area 112c are not covered by the outer frame 400, so that it is easier for the user to pull and hold District 112c. Compared with the panel structure 500, the lug portion 112 of the panel structure 600 has a larger area, so it is beneficial for a user to pull the lug portion 112.

In summary, this disclosure proposes a protective film and its application method. The protective film includes an outer film, an inner film, and a lug portion extending from the inner film. The outer film and the inner film can be removed in sections. A connecting section is provided between the lug portion and the outer membrane, so that the lug portion can be pulled while the outer membrane is removed, which is convenient for folding the lug portion to facilitate subsequent operations. When the outer membrane is removed, the inner membrane remains on the panel, and then the inner membrane is removed by pulling the folded tabs. Therefore, after the outer film is removed, the area covered by the inner film on the panel can still be properly protected, so that the protective effect of the protective film on the panel is more perfect.

This disclosure has been described by examples and the above-mentioned embodiments, and it should be understood that the present invention is not limited to the disclosed embodiments. On the contrary, the present invention encompasses various modifications and approximate arrangements (eg, as would be apparent to one of ordinary skill in the art).
