Description

Screen protective film

Technical Field

The utility model relates to a peripheral product technical field of electron especially relates to a screen protection film.

Background

Along with the development of economy and technology, electronic products such as mobile phones and flat panels are more and more popular and become an indispensable part of daily life, work and study. In the use process of electronic products, the screen of the electronic product is the most easily damaged part, and the risk of scratching and even cracking is caused by carelessness, so most users can attach a protective film on the screen.

The screen protection film which is the mainstream in the market at present is a toughened glass film, and the screen protection film is composed of an AB glue layer which takes PET as a base material and a toughened glass layer which is bonded with the AB glue layer, and has the characteristics of high hardness, low toughness and the like. The impact force born when the electronic product drops is very big, and toughened glass film toughness is low, can bear most tension that the electronic product spread out in order to reduce the tension that the screen itself bore to greatly reduced cracked risk of screen.

However, the AB glue layer uses PET as a base material, and has high hardness and low toughness, and the tempered glass film is difficult to avoid the fracture of the tempered glass film itself under the impact of external force while protecting the screen, which is not suitable for users; in addition, the PET is used as a base material, so that the overall light transmittance is difficult to further improve, and the display effect of the electronic product is influenced to a certain extent.

Disclosure of Invention

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. One or more embodiments of the present invention are illustrated in the accompanying drawings to provide a more accurate and thorough understanding of the disclosed embodiments. It should be understood, however, that the present invention may be embodied in many different forms and is not limited to the embodiments described below.

The same or similar reference numerals in the drawings of the utility model correspond to the same or similar parts; in the description of the present invention, it should be understood that if there are the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of the description, but it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore the terms describing the positional relationship in the drawings are only for illustrative purposes and are not to be construed as limitations of the present patent, and those skilled in the art can understand the specific meanings of the terms according to specific situations.

The utility model provides a screen protection film is preferably applied to the screen protection of cell-phone, electronic product such as dull and stereotyped. Fig. 1 shows a specific embodiment of the screen protection film of the present invention, and the screen protection film 100 is a transparent sheet-like structure as a whole, and its shape and size can be designed correspondingly according to the specific product model to be applied, so that it can cover the whole screen of the electronic product. In the illustrated embodiment, the screen protective film 100 is a multi-layer structure, and specifically includes a release film layer 10, an AB glue layer 20, a protective film layer 30, and the like, which are sequentially disposed.

The AB glue layer 20 includes a coating layer 22 and a first glue layer 24 and a second glue layer 26 respectively disposed on opposite sides of the coating layer 22. The coating 22 may be formed by existing coating processes and preferably has a thickness of no more than 0.1mm. The first adhesive layer 24 is preferably a silicone layer, has a thickness of about 0.01-0.2mm, and is used for bonding the release film layer 10; the second adhesive layer 26 is preferably an OCA (optical clear adhesive) adhesive layer having a thickness of about 0.02 to 0.2mm for adhering the protective film layer 30. The utility model discloses a AB glue is when the shaping, coats the corresponding side of coating 22 respectively with the solvent of the first glue film 24 of shaping, second glue film 26, forms first glue film 24, second glue film 26 and first glue film 24, coating 22, second glue film 26 structure as an organic whole after the solidification shaping promptly.

The coating 22 may be a hard coating, a self-healing coating, an anti-adhesive coating, a hybrid fusion coating, or the like, as desired. For example, the hard coat layer 22 may be a high hardness coating layer formed by coating a substrate with a diluted silicone-based resin or the like, curing the diluted silicone-based resin or the like by ultraviolet radiation, or heat curing or the like. It should be noted that the high hardness of hardcoat layer 22 is lower than the hardness of first bondline 24 and second bondline 26 than the hardness of the hardcoat layer 22 of the PET substrate. Therefore, even if the hard coating layer 22 is used as the substrate of the AB glue layer 20, compared with the existing AB glue using a PET substrate, the hardness can be effectively reduced, the flexibility can be improved, the impact resistance of the screen protection film 100 can be improved, and the possibility of cracking can be reduced.

The protective film 30 may be a tempered glass layer, a Polymethyl methacrylate (PMMA) layer, a PET layer, a composite film layer, etc., and has a thickness of about 0.05-0.45mm, which can achieve better effects of preventing external damage, scratching, etc. The release film layer 10 protects the first adhesive layer 24, and the first adhesive layer 24 is prevented from being polluted in the processes of storage, transportation and the like. When the screen protection film 100 is attached to the screen, the release film layer 10 is firstly torn, and then the first adhesive layer 24 is attached to the screen, so that the two can be tightly adhered to avoid the generation of bubbles and the like.

In some embodiments, the outer side of the protective film layer 30 is further provided with a surface coating 40, the surface coating 40 can be a waterproof oil-repellent layer, an anti-falling layer, an anti-fingerprint layer and the like, the thickness is not more than 0.05mm, and effects of pollution prevention, fingerprint prevention and the like can be achieved.

In some embodiments, another release film layer is disposed on the outer side of the surface coating layer 40, so as to protect the screen protection film 100 before use and avoid scratching during transportation, handling, etc. After the screen protective film 100 is attached to the screen, the release film layer on the surface coating 40 is also required to be torn. When the surface coating 40 is not provided, a release film layer may be directly provided on the protective film layer 30.

The utility model discloses screen protection film 100 adopts the AB glue film 20 who uses coating 22 as the substrate, can effectively improve the AB glue hardness height that uses PET to be the substrate among the prior art, the poor shortcoming of toughness, can play better cushioning effect when receiving external force, has better antidetonation effect. Simultaneously, through the replacement of coating 22 to the PET substrate, can effectively improve the optical property of product, make the utility model discloses screen protection film 100 is holistic luminousness can reach more than 93%, haze reduces to within 0.3, can present better display effect on the whole. Additionally, the utility model discloses screen protection film 100 is the combination of full glued material, can let the ability of melting soft flock and dust stronger.

It should be noted that the present invention is not limited to the above embodiments, and other changes can be made by those skilled in the art according to the spirit of the present invention, and all the changes made according to the spirit of the present invention should be included in the scope of the present invention.
