[0001] The utility model relates to the technical field of protective films, in particular to a protective film structure for improving static electricity when film is torn off. Background Art
[0002] With the popularity of digital products such as mobile phones, protective film has gradually become a general term for screen protective film, and its functions in the field of screen protective film are also varied.
[0003] After the LCM module is produced, a protective film is also pasted on the LCM module to protect it. However, for LCM modules with iron frames, static electricity from film tearing often causes abnormal display problems in the product.
[0004] In the current technology, there are two types of films for protecting LCM modules. One is a weakly sticky protective film, which is easy to produce static electricity when attached to the surface iron frame and glass, and it is easy to carry foreign matter to remain in the display area, affecting the cleanliness of the module and the display effect; the other is to add a single-sided sticky PET on the back of the weakly sticky protective film (see Figure 6 ), the non-sticky PET is in contact with the glass surface, and the sticky protective film is in contact with the surface iron frame. The advantage of this film is that it not only reduces the static electricity when tearing the film, but also avoids foreign matter remaining in the display area. However, the disadvantage of this film is that the production cost will be greatly increased, which is not economical enough.
[0005] Therefore, in view of the above-mentioned problems existing in the prior art, we have specifically designed a protective film that improves the static electricity during film tearing. Utility Model Content

[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 1-3 A protective film structure for improving film tearing static electricity includes a protective film body 1, the protective film body 1 is a protective film made of non-sticky PE material, the top and bottom of the back of the protective film body 1 are bonded with weak double-sided adhesive A2, and the side of the weak double-sided adhesive A2 away from the protective film body 1 is bonded with a release film 5; the center positions on the left and right sides of the protective film body 1 are integrally formed with hand-tear handles 3, and two metal strips 4 are fixed inside each hand-tear handle 3, and the metal strip 4 is one of aluminum sheet, iron sheet or copper sheet. The metal strip 4 has a fixed shape after being bent, and the hand-tear handle 3 with the metal strip 4 can be used to be bent to the other side of the LCM module 6, so as to clamp the left and right sides of the protective film body 1 and improve the fit with the LCM module 6.
[0030] For further information, see Figure 1-2The weak double-sided adhesive A2 is a strip structure, and the left and right sides of the weak double-sided adhesive A2 are flush with the left and right sides of the protective film body 1 respectively.
[0031] Specifically, the strip-shaped weak double-sided adhesive A2 can be adapted to the iron frame 7, so that the weak double-sided adhesive A2 can be attached to the iron frame 7 and avoid contact with the LCM module 6, which has a good protective effect on the LCM module 6.
[0032] For further information, see Figure 2 The size of the release film 5 is the same as that of the weak double-sided adhesive A2, and a handle is integrally formed on the release film 5.
[0033] Specifically, the release film 5 can protect the weak double-sided adhesive A2 before use to prevent the viscosity of the weak double-sided adhesive A2 from decreasing. The handle makes it convenient to tear off the release film 5 later to expose the sticky surface of the weak double-sided adhesive A2.
[0034] For further information, see Figure 1-3 , and also includes an LCM module 6 and an iron frame 7 arranged on the upper and lower sides of the LCM module 6. The size of the protective film body 1 is the same as that of the LCM module 6; the size of the weak double-sided adhesive A2 is the same as that of the iron frame 7. When the protective film body 1 is covered on the LCM module 6, the weak double-sided adhesive A2 is pasted on the iron frame 7, and the hand-tear handle 3 is bent and then reaches the other side of the LCM module 6.
[0035] Specifically, the iron frame 7 on the LCM module 6 of this embodiment is in a strip shape. By designing the weak double-sided adhesive A2 into a strip shape, it can be well adapted to the iron frame 7, so that the protective film body 1 is used to protect the LCM module 6.
[0036] Embodiment 2:
[0037] See also Figure 4-5 A circle of rectangular weak double-sided adhesive B8 is bonded to the back of the protective film body 1, a release film is arranged on the weak double-sided adhesive B8, and a tear handle is arranged at one corner of the weak double-sided adhesive B8; it also includes an LCM module 29 and a rectangular iron frame 210 arranged on the outside of the LCM module 29, the size of the protective film body 1 is the same as the size of the iron frame 210; the shape and size of the weak double-sided adhesive B8 are the same as the shape and size of the iron frame 210, and when the protective film body 1 covers the LCM module 29, the weak double-sided adhesive B8 is pasted on the iron frame 210.
[0038] Specifically, since the iron frame 10 in this embodiment is rectangular, the weak double-sided adhesive B8 is also designed to be a rectangular structure that is the same as and compatible with the iron frame 10, so that the protective film body 1 with the weak double-sided adhesive B8 can be used to protect the LCM module 9 with the iron frame 10. The difference from Example 1 is that one is strip-shaped and the other is rectangular. Regardless of whether the protective film body 1 with the weak double-sided adhesive A2 or the protective film body 1 with the weak double-sided adhesive B8 is used, the display area of the LCM module can be well shielded and protected, and at the same time, the double-sided adhesive residue can be prevented from contacting the LCM module, and the static electricity generated when the film is torn off can be effectively reduced.
[0039] When using:
[0040] When it is necessary to attach the protective film body 1 to the LCM module-6 with the iron frame-7, the staff can first tear off the release film 5 from the weak double-sided adhesive A2 to expose the sticky surface of the weak double-sided adhesive A2, and then attach the protective film body 1 to the LCM module-6, and make the weak double-sided adhesive A2 stick to the iron frame-7, so that the area of the protective film body 1 without the weak double-sided adhesive A2 covers the display area of the LCM module-6, and then bend the two hand-tear handles 3 respectively. Since there is a metal strip 4 in the hand-tear handle 3, the hand-tear handle 3 can be bent to the other side of the LCM module-6 (the side without the protective film body 1) and keep the bent state, and the bending of the hand-tear handle 3 is used to limit and stabilize the left and right sides of the protective film body 1, thereby improving the stability of the protective film body 1 on the LCM module-6;
[0041] When the protective film body 1 needs to be torn off from the LCM module 6 later, the tear handle 3 is first bent to make the tear handle 3 and the protective film body 1 parallel, and then the tear handle 3 can be grasped to easily tear off the protective film body 1 from the LCM module 6, so that the weak double-sided adhesive A2 is separated from the iron frame 7;
[0042] When using the protective film body 1 in Example 2, it is also necessary to first tear off the release film on the weak double-sided adhesive B8, then cover the protective film body 1 on the LCM module 2 9, and attach the weak double-sided adhesive B8 to the iron frame 2 10.
[0043] 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.
