It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, an AB glue protection film, including toughened glass 1, AB glue film 2 and dust ring 3, AB glue film 2 from the top down is OCA glue film 21, blooming base material 22, pressure sensitive adhesive layer 23 in proper order and leaves type membrane 24, OCA glue film 21 deviates from blooming base material 22 one side with 1 laminating of toughened glass, be provided with a plurality of micropores on the pressure sensitive adhesive layer 23, toughened glass 1 with AB glue film 2 is provided with the camera hole 11 of intercommunication, dust ring 3 demountable installation be in camera hole 11. Specifically, in this embodiment, the AB adhesive layer 2 is the OCA adhesive layer 21, the optical film substrate 22, the pressure-sensitive adhesive layer 23 and the release film 24 from top to bottom in proper order, the OCA adhesive layer 21 is directly attached to the tempered glass 1, when the user uses the device, the release film 24 can be directly torn off by hand, the pressure-sensitive adhesive layer 23 can be adhered to the display screen (not shown in the figure), the pressure-sensitive adhesive layer 23 can be adhered to the smooth display screen, the surface of the display screen cannot be polluted, and no trace is left on the surface of the display screen after the protective film is torn off. Further, be provided with a plurality of micropores on pressure-sensitive adhesive layer 23, because pressure-sensitive adhesive layer 23 is very sensitive to pressure, consequently, when the user applys pressure to toughened glass 1 surface with the hand, pressure-sensitive adhesive layer 23 presss from both sides between optical film substrate 22 and display screen, pressure-sensitive adhesive 23 can be followed all around the direction diffusion, and pressure-sensitive adhesive 23 fills the micropore automatically when the diffusion, avoids pressure-sensitive adhesive 23 to rise the fold after the pressurized, leads to toughened glass 1 surface unevenness, and user's use experiences not good. Further, be provided with the camera hole 11 of intercommunication on toughened glass 1 and AB glue film 2, camera hole 11 is just corresponding with the camera on the display screen, 3 covers of dust ring are established in camera hole 11, and with the display screen butt, pile up the dust back in the clearance of dust ring 3 and display screen junction, the user can directly use tweezers to pick out dust ring 3, use 3 inner circles of soft brush clearance dust ring and the butt of display screen and dust ring 3 to be handled, it is very convenient to clear up, and can not harm the display screen, need not change whole protection film, very big reduction use cost.
