Under the trend of continuous upgrading of data products, communication tools have developed from the most primitive telegraph to the smart phone at this time. People use mobile phones more and more frequently, and users face the problem of accidental falling of mobile phone screens and cracks every day. At this time, the mobile phone film industry relies on people's psychological protection to protect mobile phone screens. When many users buy a mobile phone, the first thing is to put a mobile phone film on the screen, but the quality of the tempered film for mobile phones on the market is uneven, and the price varies greatly. How should we choose?
Tools/ Materials
Tempered glass with the theme of tempered glass.
IF coating, there is a layer of IF coating on the tempered glass, also called anti-fingerprint treatment coating.
AB glue, under the tempered glass is a layer of AB glue method/step.
Hardness
According to the content of the popular science article "How to talk about life without a good film for mobile phone film" on the platform of the quality life circle, most of the tempered glass films on the market are written with Mohs hardness above 6, which means that except for sand, Knives, nails, keys, etc. can not cause damage to it, the hardness of the plastic film is only 2-3, it is easy to scratch. Whether it is a tempered film or a plastic film, the surface should be free of scratches and scratches after the 9H pencil hardness test.
Light transmittance
The outer packaging of many mobile phone films will be marked with "light transmittance of 99%". This statement has no scientific basis and is completely deceiving consumers. The standard transmittance data should be expressed as: ≥90.0%. No matter how high-end the film will affect the brightness and color transfer of the mobile phone to a certain extent, the film that does not affect the display effect of the mobile phone screen has not yet appeared.
Wear resistance
The professional test is to use 0000# steel wool to rub back and forth 1500 times on each mobile phone film to test the wear resistance of the mobile phone film. Consumers should pay attention when purchasing, the mobile phone film has a service life, its anti-fingerprint layer will be worn after a period of use, and the AB glue behind will gradually age, so even the best mobile phone is tempered The film is also recommended to be updated every six months.
Water drop angle
It is mentioned in the quality life circle that there are many mobile phone films on the market under the banner of "3D hand gel film". We can do a small test to determine whether this mobile phone film is good or not, and drop a drop of water on the tiled phone. On the surface of the film, if the water droplets are spread out and the angle of the water droplets is less than 110°, then the tempering technology of this mobile phone film is not very good. When consumers buy a mobile phone, they can try a drop of water on the film, and choose the one with a relatively rounded water droplet shape.
