Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-2, the bendable protective film for a high-flexibility curved screen comprises a protective layer 5, a buffer layer 4, an adhesive layer 301, a reinforcing layer 3, an explosion-proof layer 302, an isolation layer 2 and a light-transmitting layer 1 are respectively arranged below the protective layer 5 from top to bottom, and the upper surface of the protective layer 5 is frosted.

Through above-mentioned technical scheme, the frosting treatment is done to 5 upper surfaces of protective layer can effectively avoid the reflection of light problem, has played very big effect to the human eye protection, and protective layer 5 adopts high light transmissivity, high tenacity, high strength and flexible LLDPE material simultaneously, also known as linear low density polyethylene material, can make protective layer 5 protect the fragile buffer layer 4, bond line 301, back up coat 3, explosion-proof layer 301, isolation layer 2 and euphotic layer 1 that its below set up.

In this embodiment, protective layer 5 below is equipped with buffer layer 4, and seamless laminating between buffer layer 4 and the protective layer 5, buffer layer 4 adopt be AR material protection film, have not reflect light, high transmittance, the texture softness of itself has antifriction anti-scraping ability, can also the screen of effectual protection digital product not by the scratch under the condition that does not influence screen display effect.

It should be noted that, the bonding layer 301 is arranged below the buffer layer 4, the reinforcing layer 3 is bonded below the bonding layer 301, the material used by the bonding layer 301 is an OCA optical cement, and is one of important raw materials of the touch screen, and the touch screen has the advantages of high light transmittance, high color clarity, high adhesion, water resistance, high temperature resistance, ultraviolet resistance and the like, so that glare emitted by the screen can be reduced, human eyes can be protected, screen light emission loss can be reduced, brightness can be increased, high transmittance can be provided, energy consumption of digital products can be reduced, the reinforcing layer is made of a PET material, and the touch screen has good impact resistance, transparency and high folding resistance, and is used for further protecting other structures from being damaged under strong impact.

Wherein, the below of back up coat 3 is equipped with explosion-proof layer 302, and explosion-proof layer 302 is inside to be the cavity reticulation, adopts PE synthetic fiber, still has stronger cohesiveness when having high obdurability, can tightly glue the material of laminating together for the protection can not appear cracked in each layer and digital product screen itself above explosion-proof layer 302 under the high strength strikes.

In this embodiment, explosion-proof layer 302 below is equipped with isolation layer 2, and isolation layer 2 and explosion-proof layer 302 laminating, 2 inside contain of isolation layer prevent the blue light master batch, make the surface scribble silver nanometer coating through coating film technology, still have certain antibiotic effect when keeping apart the blue light and cause the injury to people's eye, effective protection user's health safety.

The lower part of the isolation layer 2 is provided with the euphotic layer 1, the euphotic layer 1 is seamlessly attached to the isolation layer 2, the euphotic layer 1 is made of TPU material, the surface is polished smoothly, the TPU material only has high toughness, the texture is soft but the strength is insufficient, so that the TPU material is arranged at the lowermost layer and is tightly attached to a digital equipment screen, the screen can be effectively protected from being scratched, meanwhile, the TPU material has extremely high wear resistance, high-energy-ray resistance, high tensile strength, large elongation, high light transmittance and good resistance to oils and many solvents; the TPU also has the obvious advantages of good weather resistance, tear resistance, high flexural strength and tensile strength, high elongation, low long-term compression set deformation rate and the like, so that the TPU can be tightly attached according to different shapes of screens without influencing the display effect of the screens.

This high pliability curved surface screen is with theory of operation of the protection film of can buckling:

during the use, when light passes through euphotic layer 1, because the high light transmissivity of euphotic layer 1 makes the light that jets out almost not have the loss and just reached isolation layer 2, the inside blue light master batch of preventing of isolation layer 2 can the effectual blue light that shields digital product screen and send, thereby reach the effect of protection people's eye, light after having filtered the blue light reachs explosion-proof layer 302 after penetrating isolation layer 2, explosion-proof layer 302 is inside to be become netted increase luminousness that can the very big degree, further reduce the light loss, and the strong adhesion that explosion-proof layer 302 itself had can guarantee closely laminating between the upper and lower layer structure, receive the striking externally and make the cracked phenomenon of being difficult for having, pass the permeability afterwards in proper order, back up coat 3 that the light transmissivity is good, bond line 301 reaches buffer layer 4, buffer layer 4's not reflection of light, high light transmissivity, itself texture is soft has antifriction anti-scraping ability, can also can be under the circumstances that does not influence screen display effect can effectual protection digital product's screen not scratched by scratch And finally, the protective layer 5 on the surface is reached, and the surface of the protective layer 5 is frosted and polished, so that the reflection of light on the surface of the protective film is minimized, dust and bacteria are not easy to leave due to the frosted material, and the eyes of a user can be further protected.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
