The utility model discloses a main objective provides a protection film structure aims at solving prior art, and the protection film that has the function hole is less with the bonding force of apron, and the problem that the protection film that has the function hole dropped from the apron easily.
Example 1
Please refer to fig. 1-3.
The protective film structure comprises a first film layer 100 and a second film layer 200;
wherein, the surface of the first film layer 100 is not provided with glue, referring to fig. 1, the second film layer 200 is provided with a through hole 210, the second film layer 200 is attached to the lower surface of the first film layer 100, the through hole 210 is covered by the first film layer 100, and the surface of the second film layer 200 departing from the first film layer 100 is provided with a first glue layer 300 adapted to the shape of the second film layer 200.
In this embodiment, referring to fig. 1, the lower surface of the second film layer 200 is provided with a first adhesive layer 300, the protective film structure is adhered to the member to be adhered (e.g., the cover plate) through the first adhesive layer 300, the member to be adhered is provided with a functional hole, in this embodiment, the through hole 210 is aligned with the functional hole, and when the protective film structure is adhered to the cover plate, the first adhesive layer 300 is directly adhered to the cover plate, so that the protective film structure is firmly adhered to the cover plate.
In the embodiment, since the lower surface of the first film layer 100 is not coated with glue, and the through hole 210 in the second film layer 200 is aligned with the functional hole, the lower surface of the second film layer 200 does not need to be provided with a spacer to isolate the glue, so as to prevent the glue from entering the through hole 210 and finally polluting the functional hole, because the spacer is not required to be provided in the second film layer 200, the second film layer 200 can be directly attached to the cover plate through the first glue layer 300; the second rete 200 that does not set up the spacer is more for leveling, and when second rete 200 was attached on the apron through first glue film 300, there can not be bending stress, and second rete 200 is also more level and more smooth through first glue film 300 and apron are attached, and then makes second rete 200 through first glue film 300 and apron are attached comparatively firm, the reduction protection film structure that can be great is attached and appears the possibility that drops on the apron.
In this embodiment, the functional hole may be specifically an IR hole or a camera hole.
In this embodiment, the protective film structure can be set to be a bang type, a beauty tip type or a hole digging type to adapt to the existing mobile phone screen of the bang type, the beauty tip type or the hole digging type.
Specifically speaking, when the mobile phone screen is of a bang type, a beauty tip type or a hole digging type, the piece to be pasted is a cover plate, the screen printing area of printing ink of the display screen cover plate of the mobile phone is smaller and smaller, the bonding area between the periphery of a functional hole in the cover plate and the protective film structure is smaller and smaller, in the embodiment, the arrangement of a spacer is cancelled in the protective film structure, so that the lower surface of the protective film structure is very flat and flat without any height difference, namely, when the protective film structure is bonded with the cover plate, bending stress cannot exist between the protective film structure and the cover plate, the lower surface in the protective film structure (namely the lower surface of a first glue layer) and the cover plate have a bonding effect, and further the bonding force between the protective film structure and the cover plate is improved.
In this embodiment, the protection film structure further includes a second adhesive layer 400, and the second film layer 200 is attached to the first film layer 100 through the second adhesive layer 400.
Specifically, the first film layer 100 is bonded to the second film layer 200 through the second adhesive layer 400, and the second adhesive layer 400 is adapted to the shape of the second film layer 200; it is ensured that no glue is applied directly over the through-hole 210 as shown in fig. 1, avoiding the glue from entering the through-hole 210.
In this embodiment, the first film layer 100 and the second film layer 200 have the same top view shape, and referring to fig. 2 specifically, when the first film layer 100 is adhered to the second film layer 200 through the second adhesive layer 400, the adhesion stability of the first film layer 100 and the second film layer 200 can be improved, and the aesthetic degree of the whole protective film structure can be improved.
In this embodiment, the second adhesive layer 400 is a double-sided adhesive tape, and the double-sided adhesive tape 400 is transparent, specifically, the second adhesive layer 400 is a double-sided adhesive tape, which can avoid using glue as the second adhesive layer 400, and further avoid that glue enters the through hole 210 and finally pollutes the functional hole when using glue as the second adhesive layer 400.
When the second film layer 200 is adhered to the cover plate through the first adhesive layer 300, the adhering strength between the second film layer 200 and the cover plate can be ensured, and the thickness of the first adhesive layer 300 can be reduced, so that the effect of reducing the overall thickness of the protective film structure is finally achieved.
In the present embodiment, the first adhesive layer 300 is specifically an acrylic adhesive layer.
In this embodiment, the protection film structure is equipped with handle 500, handle 500 is attached on first glue film 300, handle 500's effect is used for conveniently taking apart the protection film structure, under general conditions, before attaching the protection film structure at the apron, the protection film structure is packaged, specifically paste on first glue film 300 through a rete, when needs are attached the protection film structure on the apron, accessible pulling handle 500 with the protection film structure with attached membrane separation at first glue film 300, can avoid the staff to pollute first rete 100.
In this embodiment, the first film layer 100 is made of a transparent PET material, and specifically, the first film layer 100 covers the through hole 210, and the transparent PET material is used as the first film layer 100, so as to improve the light transmittance of the functional hole.
In this embodiment, the second film layer 200 is also made of transparent PET.
In the embodiment, the thickness of the first film layer 100 is between 0.025 mm and 0.035mm, the thickness of the second film layer 200 is between 0.045 mm and 0.055mm, the thickness of the first glue layer 300 is between 0005 mm and 0.015mm, and the thickness of the second glue layer 400 is between 0.025 mm and 0.035 mm.
Specifically, the thickness of the whole protective film structure is between 0.115 mm and 0.14mm, and the whole protective film structure is thin and can be adapted to display modules in various terminals, such as mobile phone screens, tablet computer screens, notebook computer screens, desktop computer screens, television screens and the like.
In this embodiment, the protection film structure includes first rete 100, second rete 200 and first glue film 300, second rete 200 is equipped with through-hole 210, attach on second rete 200 on first rete 100, and the through-hole 210 is covered by first rete 100, can avoid glue to get into in the through-hole 210, and then avoid polluting the functional hole that corresponds with through-hole 210, need not to set up the spacer and surround the functional hole on the apron, it is more level and more smooth when making first glue film 300 paste with the apron, and then improve being stained with of first glue film 300 and apron and attach the intensity.
The arrangement of the first film layer 100 can also prevent dust from entering the through hole to contaminate the through hole, thereby contaminating the functional hole.
