Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a protective film structure which is beneficial to removing bubbles. Background Art

[0002] After the production of a liquid crystal display product is completed, it is usually necessary to stick a protective film on its cover plate, so as to protect the cover plate with the protective film.

[0003] During the production of some cover plates, the cover plates will be processed to eliminate the bubbles formed after the protective film is applied. Common surface treatment processes include AG, AR and AF (the reason why the AF treatment process helps to eliminate bubbles is mainly because the material used in the AF process is hydrophobic, which helps the bubble flow. The bubbles can be driven from the middle position to the edge through squeezing and finally discharged from the coverage of the protective film). These surface treatment processes can be used alone or in combination to allow LCD display products to achieve different display effects and usage effects.

[0004] However, if the surface of the cover plate is not subjected to AF treatment, when bubbles are generated when the protective film is attached to the cover plate, it is difficult to drive all the bubbles from the middle position to the edge (the bubbles between the protective film and the cover plate mainly appear near the middle position), and finally out of the coverage of the protective film. In addition, under high temperature conditions, bubbles may be printed on the cover plate, resulting in poor appearance. Although the AF process can be used on the cover plate to eliminate bubbles, this method is relatively more expensive and requires higher precision.

[0005] Therefore, in order to solve the problem that bubbles are easily generated after the existing protective film is attached to the cover plate, we have specifically designed a protective film structure that is conducive to eliminating bubbles. Utility Model Content

[0006] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective film structure that is conducive to removing bubbles, including a protective film, wherein the protective film includes a protective film body, a release film 1 and a release film 2; the release film 1 is attached to one side of the protective film body, and the release film 2 is attached to the other side of the protective film body; a plurality of defoaming cuts A are arranged on the surface of the protective film body near the middle, and a shielding sheet A is formed at the defoaming cut A.

[0008] As a further solution of the utility model: the defoaming incision A is cut, and the defoaming incision A has two sides and forms a sharp angle shape, and the sharp angle gradually decreases from left to right.

[0012] As a further solution of the utility model: the inner cavity of the release film 1 and the release film 2 and the positions near the edges are both rectangularly provided with reinforcing wires, and the reinforcing wires are made of aluminum wires or iron wires.

[0013] As a further solution of the utility model: the size of the release film 1 and the release film 2 are the same as the size of the protective film body, and the thickness of the release film 1 and the release film 2 are both smaller than the protective film body.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] In the present application, multiple defoaming incisions A are designed near the middle of the protective film body. When bubbles exist when the protective film body is attached to the cover body, the bubbles can be pushed out from any defoaming incision A. The operation is simpler, the moving distance of the bubbles is shorter, and it is easier to be completely discharged. This can replace the current solution of adding AF surface treatment to the cover body. This method can also solve the problem of bubbles existing when the protective film body is attached to the cover body. There will be no bubble marks under high temperature conditions. Compared with the existing technology of adding AF coating to the cover body, the cost of opening multiple incisions on the protective film will be lower, and the precision requirements will also be lower.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-5 , a protective film structure that is conducive to removing bubbles, includes a protective film, the protective film includes a protective film body 1, a release film 1 2 and a release film 2 3; a tearing handle 3 6 is integrally formed on the top of one side of the protective film body 1, and the surface of the tearing handle 3 6 is provided with anti-slip patterns, the tearing handle 3 6 can be conducive to tearing off the protective film body 1 from the cover plate body 9 later, and the anti-slip patterns can increase the friction when grasping, the release film 1 2 is attached to one side of the protective film body 1, and the release film 2 3 is attached to the other side of the protective film body 1; a plurality of defoaming cuts A4 are provided on the surface of the protective film body 1 and near the middle, and a shielding sheet A5 is formed at the defoaming cut A4, and also includes a backlight and liquid crystal display panel assembly 8 and a cover plate body 9, the backlight and liquid crystal display panel assembly 8 is installed on one side of the cover plate body 9, and the protective film body 1 is attached to the other side of the cover plate body 9.

[0030] For further information, see Figure 2-3 , a defoaming incision A4 is cut, the defoaming incision A4 has two sides and forms a sharp angle shape, the sharp angle gradually decreases from left to right, one side of the shielding piece A5 is connected to the protective film body 1, and the shielding piece A5 is closed in the defoaming incision A4.

[0031] Specifically, after the defoaming incision A4 is cut on the protective film body 1, a shielding piece A5 is formed at the cutting position, and the shielding piece A5 does not separate from the protective film body 1, which is conducive to the subsequent shielding piece A5 being directly closed in the defoaming incision A4 and attached to the cover plate body 9 together with the protective film body 1. The defoaming incision A4 is cut in a pointed shape, so only two edges need to be cut, which can shorten the cutting time.

[0032] For further information, see Figure 3 The multiple defoaming cuts A4 are all far away from the edge of the protective film body 1, and the distance between each defoaming cut A4 and the edge of the protective film body 1 is greater than or equal to 20 mm.

[0033] Specifically, the multiple defoaming cuts A4 are all close to the middle of the protective film body 1 and have a certain distance from the edge of the protective film body 1, so as to prevent the protective film body 1 from falling off the cover plate body 9 and leave enough area for complete attachment.

[0034] For further information, see Figure 1 A film tearing handle 201 is integrally formed on the left middle part of the release film 1 2 , and a film tearing handle 2 301 is integrally formed on the left middle part of the release film 2 3 . Both the film tearing handle 201 and the film tearing handle 2 301 are provided with anti-slip patterns.

[0035] Specifically, since the sharp corner of the defoaming cut A4 on the protective film body 1 is facing the right side, in order to prevent the defoaming cut A4 from lifting up when the release film 1 2 and the release film 2 3 are torn off from the protective film body 1, the film tearing handle 1 201 and the film tearing handle 2 301 are respectively arranged on the left sides of the release film 1 2 and the release film 2 3. Therefore, when the release film 1 2 and the release film 2 3 are torn off, the tearing direction is from left to right, thereby avoiding the defoaming cut A4 from lifting up.

[0036] For further information, see Figure 4 A rectangular reinforcing wire 7 is provided in the inner cavity of the release film 1 2 and the release film 2 3 and near the edge. The reinforcing wire 7 is made of aluminum wire or iron wire.

[0037] Specifically, by setting reinforcing wire 7 inside release film 1 2 and release film 2 3, the flatness and integrity of release film 1 2 and release film 2 3 can be improved, so that release film 1 2 and release film 2 3 can better protect the protective film body 1 and reduce the probability of wrinkles on the protective film body 1 during storage or transportation.

[0038] For further information, see Figure 1 The sizes of the release film 1 2 and the release film 2 3 are the same as that of the protective film body 1 , and the thicknesses of the release film 1 2 and the release film 2 3 are smaller than that of the protective film body 1 .

[0039] Specifically, by designing release film 1 2 and release film 2 3, the front and back sides of the protective film body 1 can be shielded and protected. On the one hand, the protective film body 1 is prevented from being affected by the outside world as a whole. On the other hand, wrinkles on the shielding piece A5 on the protective film body 1 are avoided, and the shielding piece A5 can always be closed in the defoaming incision A4.

[0040] Embodiment 2:

[0041] See also Figure 6 A plurality of defoaming cuts B10 are cut on the surface of the protective film body 1, and the defoaming cuts B10 are U-shaped. A shielding piece B1001 is formed at the defoaming cuts B10, and the shielding piece B1001 is closed in the defoaming cuts B10; the plurality of defoaming cuts B10 are all away from the edge of the protective film body 1, and the distance between each defoaming cut B10 and the edge of the protective film body 1 is greater than or equal to 20 mm.

[0042] Specifically, based on Example 1, by setting up Example 2, defoaming incisions of different shapes can be selectively opened on the protective film body 1, such as the above-mentioned U-shaped (flipped U-shaped) defoaming incision B10. The number of defoaming incisions B10 is greater and smaller than the number of defoaming incisions A4 in Example 1. The advantages are that the coverage range is wider, the distance of bubble activity is shorter, and it is more convenient to discharge from the nearby defoaming incision B10. However, compared with Example 1, which only requires two side cutting, Example 2 requires three side cutting, and the cutting time is longer than Example 1. Therefore, on the premise that the defoaming incision A4 and the defoaming incision B10 have the same usage and can both discharge bubbles, the production unit can selectively choose the defoaming incision A4 or the defoaming incision B10 according to actual conditions.

[0043] When in use: when the protective film body 1 needs to be attached to the cover body 9, the user can first tear off the release film 2 3 through the tearing handle 2 301 to expose one side of the protective film body 1, and attach the exposed side to the cover body 9, and then tear off the release film 1 2 through the tearing handle 1 201 to expose the other side of the protective film body 1;

[0044] When bubbles exist when the protective film body 1 is attached to the cover body 9, the bubbles can be squeezed toward any debubbling cutout A4, so that the bubbles are discharged from the debubbling cutout A4 closest to it until all the bubbles on the protective film body 1 are discharged. After the bubbles are discharged, the shielding sheet A5 can be pressed to close the shielding sheet A5 in the debubbling cutout A4 and fit onto the cover body 9.

[0045] It should be noted that if the protective film body 1 with the defoaming cutout B10 in Example 2 is used to attach to the cover plate body 9, its use is the same as that in the above-mentioned Example 1, so it will not be described here.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
