With the increasing scale of the mobile phone market, a series of accessory products headed by screen film are also in full bloom. Dustproof film, tempered film, privacy film, porcelain crystal film, frosted film are dazzling, making it difficult to choose .
After getting the mobile phone film, its appearance and material must be the first thing users notice. Our test starts with the subjective perception.
1 Oleophobic layer test
The first thing to do is the oleophobic layer test: In order to ensure the user’s daily use experience, most of the mobile phone tempered films now have an oleophobic coating. This type of AF anti-fingerprint coating has extremely low surface tension, and ordinary water droplets, Oil droplets can maintain a large contact angle when they touch the surface of the material, and aggregate into water droplets by themselves, which is easy for users to clean.
Although the principles are similar, the spraying process of the oleophobic layer is also different. At present, the mainstream processes on the market are plasma spraying and vacuum plating coating. The former uses plasma arc to clean the glass first, and then sprays the oleophobic layer. The combination is closer, which is the mainstream treatment process on the market at present; the latter sprays anti-fingerprint oil onto the glass in a vacuum environment, which is stronger overall and has the highest wear resistance.
2 With or without earpiece dustproof & body arc edge treatment
I believe that old iPhone users must have the impression that after using their iPhone for a long time, the microphone above the fuselage will always accumulate a lot of dust and stains, which not only affects the sound playback, but also the overall look and feel is very poor. For this reason, some tempered films specially designed for the iPhone series have added “earpiece dust-proof holes”, which can not only isolate dust while ensuring normal volume playback, but also play a waterproof role.
3 hardness test
If you want to ask mobile phone users why they need to replace the mobile phone film, the answer of “too many scratches” will definitely not be less. Who usually does not carry a key, cigarette case, etc. in their pockets when they go out, and once scratches appear, the overall look and feel of the mobile phone screen will change. dramatically drop.
4 Drop ball test
Some friends may ask, what is the significance of this ball drop test? In fact, the main test of this item is the impact resistance of the tempered film. The higher the height of the ball, the stronger the impact force. The current tempered film is mainly made of lithium-aluminum/high-aluminum materials, and has undergone secondary treatment, which is basically very tough.
