Description

Technical Field

[0001] The utility model relates to the technical field of camera hole protection, in particular to a protective film structure for a camera hole of a display module. Background Art

[0002] At present, smart phones are very popular, and more and more people like to use the mobile phone camera to record their lives. Therefore, people have higher and higher requirements for the photo-taking and video-recording effects of mobile phone cameras. During the manufacturing process of mobile phone modules, after the main body of the camera hole of the display panel is made, steps such as defoaming, testing, and UV curing are required. During this process, a protective film needs to be set on the camera hole. Setting this protective film can not only prevent damage to the camera hole during the manufacturing process, but also avoid foreign objects in the camera hole caused by environmental pollution during logistics handling.

[0003] As Figure 1 and Figure 2 shown, a camera hole 112 is provided on a mobile phone display module 111. Before the display module 111 is shipped, a protective film 113 needs to be attached to the camera hole 112 to protect the camera hole from being contaminated. In the existing protective film 113 structure of the camera hole 112 of the display module 111, the position of the camera hole 112 is a non-ink area, and the protective film 113 is also non-adhesive at the camera hole position. The adhesive area 114 has the thickness of the ink + the thickness of the glue, and there is a height difference of 0.01 - 0.03 mm at this position. The effective adhesive area of the glue is small, and the gap 116 between them easily causes the protective film 113 to warp and shift. In addition, a tear handle 115 is provided on the side of the camera hole 112, and the direction of the tear handle 115 faces outward, which is easy to be collided, resulting in the protective film 113 warping, shifting, and falling off.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] As described in the background art, there is a height difference between the protection film and the adhesive area, and the small effective adhesive area easily causes the protection film to warp and shift. Moreover, a tear handle is provided on the side of the camera hole, and the direction of the tear handle faces outward, which is easy to collide and cause the protection film to warp, shift, and fall off.

[0033] To solve this technical problem, the present utility model provides a camera hole protection film structure for a display module, which improves the height difference of the existing camera hole protection film and can prevent the non-adhesive film from warping.

[0034] Specifically, please refer to Figures 3-6 , the camera hole protection film structure for a display module specifically includes:

[0035] A non-adhesive film 1 and a tear handle 6. The non-adhesive film 1 has a camera protection area 2 and an adhesive area 3. The camera protection area 2 is used to cover the camera hole of the display module, and the adhesive area 3 is used to bond with the edge of the camera hole of the display module. A single-sided sticker 4 is fixedly connected to the lower surface of the adhesive area 3, and an ink layer 5 is fixedly connected to the lower surface of the single-sided sticker 4. The thickness of the camera protection area 2 is the same as the sum of the thicknesses of the adhesive area 3, the single-sided sticker 4, and the ink layer 5; the tear handle 6 is fixedly connected to the adhesive area 3, and the end of the tear handle 6 away from the adhesive area 3 is bent towards the camera protection area 2.

[0036] The protective film structure for the camera hole of the display module provided by the present utility model has a non-adhesive film 1 attached to the camera hole of the mobile phone during use. The non-glue and transparent camera protection area 2 covers the camera hole, thereby protecting the camera hole from being contaminated. By tearing the handle 6 to tear the pasting area 3 of the non-adhesive film 1, it is possible to avoid glue remaining on the camera hole during the film tearing process. Since the thickness of the camera protection area 2 is the same as the sum of the thicknesses of the pasting area 3, the single-sided sticker 4, and the ink layer 5, it can be better bonded to the edge of the camera hole, improving the height difference of the camera hole of the existing protective film, preventing the non-adhesive film 1 from warping. At the same time, the tear handle 6 on the non-adhesive film 1 is folded inward in the reverse direction, changing the structure of the existing protective film facing outward, making the non-adhesive film 1 not easily be bumped and warped or displaced, and effectively preventing the non-adhesive film 1 from falling off.

[0037] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] Please refer to Figures 3-6 , a protective film structure for the camera hole of a display module, which includes a non-adhesive film 1 and a tear handle 6. The non-adhesive film 1 has a camera protection area 2 and a pasting area 3. The camera protection area 2 is used to cover the camera hole of the display module, and the pasting area 3 is used to bond to the edge of the camera hole of the display module. The lower surface of the pasting area 3 is fixedly connected with a single-sided sticker 4, and the lower surface of the single-sided sticker 4 is fixedly connected with an ink layer 5. The thickness of the camera protection area 2 is the same as the sum of the thicknesses of the pasting area 3, the single-sided sticker 4, and the ink layer 5. The tear handle 6 is fixedly connected to the pasting area 3, and one end of the tear handle 6 far from the pasting area 3 is bent towards the camera protection area 2.

[0041] Please refer to Figure 3 、 Figure 5 and Figure 6, when in use, the non - adhesive film 1 is attached to the mobile phone camera hole, and the non - adhesive and transparent camera protection area 2 covers the camera hole, thus protecting the camera hole from being contaminated. By tearing the handle 6 to tear the pasting area 3 of the non - adhesive film 1, it can be avoided that glue remains on the camera hole during the film - tearing process. Since the thickness of the camera protection area 2 is the same as the sum of the thicknesses of the pasting area 3, the single - sided sticker 4, and the ink layer 5, it can better bond with the edge of the camera hole, improving the height difference of the existing protective film at the camera hole, preventing the non - adhesive film 1 from warping. At the same time, the tear handle 6 on the non - adhesive film 1 is folded inward reversely, changing the structure of the existing protective film facing outward, making the non - adhesive film 1 not easily be bumped and warped or displaced, and effectively preventing the non - adhesive film 1 from falling off.

[0042] Further optimize the camera hole protective film structure of the display module provided in Embodiment 1. Specifically, as Figure 5 shown, the non - adhesive film 1 is made of transparent and anti - static PET material, and the non - adhesive film 1 is MAXSUN MX - 50T - 2ESD.

[0043] Through the above - mentioned structural design, the non - adhesive film 1 is attached to the mobile phone camera hole, and the non - adhesive and transparent camera protection area 2 covers the camera hole, thus protecting the camera hole from being contaminated.

[0044] Further optimize the camera hole protective film structure of the display module provided in Embodiment 1 or 2. As Figure 5 and Figure 6 shown, the single - sided sticker 4 includes a PET layer 401 and an adhesive layer 402 fixedly connected to the PET layer 401. The PET layer 401 is fixedly connected to the non - pasting area 3, and the adhesive layer 402 is bonded to the ink layer 5. The single - sided sticker 4 is made of 3M's 3M244 material. Such a setting makes the single - sided sticker 4 a double - layer structure, and the adhesive layer 402 is used for pasting with the cover plate ink layer 5.

[0045] Further optimize the camera hole protective film structure of the display module provided in the above - mentioned embodiments. As Figure 3 shown, the surface of the tear handle 6 is mixed with one or more colors among red, orange, yellow, blue, or green. The non - adhesive film 1 and the tear handle 6 are of an integrally formed structure. With such a structural design, different colors can be set for the tear handle 6 for easy distinction and identification by operators.

[0046] Further optimize the camera hole protective film structure of the display module provided in the above - mentioned embodiments. As Figure 4 and Figure 5 shown, the transition between the tear handle 6 and the pasting area 3 is through an arc. A plurality of through - holes 7 are opened at the bending part between the tear handle 6 and the pasting area 3. The through - holes 7 are of a circular structure. The arc transition reduces the stress between the tear handle 6 and the pasting area 3, preventing tearing during the film - tearing process. Opening the through - holes 7 at the bending part between the tear handle 6 and the pasting area 3 facilitates the inward folding of the tear handle 6 and prevents the phenomenon of springback;

[0047] As Figure 6 and Figure 7 shown, the camera protection area 2 includes a base layer 8 and a transparent gasket 9. The base layer 8 is adhesively fixed to the transparent gasket 9 through PU glue. The thickness of the base layer 8 is the same as that of the pasting area 3. The sum of the thicknesses of the transparent gasket 9, the single-sided sticker 4 and the ink layer 5 is the same. The size of the transparent gasket 9 is the same as that of the camera hole of the display module.

[0048] With such a structural design, the base layer 8 and the transparent gasket 9 are adhesively fixed through PU glue to form a glue-free area. During use, the non-sticky transparent gasket 9 is attached to the camera hole of the mobile phone. The non-sticky and transparent transparent gasket 9 is used to cover the camera hole, thereby protecting the camera hole from being polluted. It can avoid residual glue in the camera hole area. At the same time, the non-sticky film 1 does not need to be separately processed for the camera protection area 2. Only by adhesively fixing the base layer 8 to the transparent gasket 9 through PU glue can the camera protection area 2 be formed, thereby making the processing of the non-sticky film 1 more convenient and reducing the material cost.

[0049] The using process of the camera hole protection film structure of the display module provided by the present utility model is as follows:

[0050] During use, the non-sticky film 1 is attached to the camera hole of the mobile phone. The non-sticky and transparent camera protection area 2 is used to cover the camera hole, thereby protecting the camera hole from being polluted. By tearing the handle 6, the pasting area 3 of the non-sticky film 1 can be torn off, which can avoid residual glue on the camera hole during the film tearing process. Since the thickness of the camera protection area 2 is the same as the sum of the thicknesses of the pasting area 3, the single-sided sticker 4 and the ink layer 5, it can be better adhesively bonded to the edge of the camera hole, improving the height difference of the camera hole of the existing protection film and preventing the non-sticky film 1 from warping. The tear handle 6 can be set in different colors for easy distinction and identification by the operator. At the same time, the tear handle 6 on the non-sticky film 1 is folded inward reversely, changing the structure of the existing protection film facing outward, making the non-sticky film 1 not easily be collided, warped or displaced, and effectively preventing the non-sticky film 1 from falling off. By opening a through hole 7 at the bending part between the tear handle 6 and the pasting area 3, it is convenient for the tear handle 6 to be folded inward and prevent the phenomenon of rebound. And the camera protection area 2 includes a base layer 8 and a transparent gasket 9. The base layer 8 and the transparent gasket 9 are adhesively fixed through PU glue to form a glue-free area. During use, the non-sticky transparent gasket 9 is attached to the camera hole of the mobile phone. The non-sticky and transparent transparent gasket 9 is used to cover the camera hole, thereby protecting the camera hole from being polluted. It can avoid residual glue in the camera hole area. At the same time, the non-sticky film 1 does not need to be separately processed for the camera protection area 2. Only by adhesively fixing the base layer 8 to the transparent gasket 9 through PU glue can the camera protection area 2 be formed, thereby making the processing of the non-sticky film 1 more convenient and reducing the material cost.
