For most people, mobile phones are a very high-strength electronic product. The more time the mobile phone is used, the more likely the screen is to scratch, break, etc. Many friends will choose to buy a mobile phone film once and for all, and various mobile phone films appear on the market.
Is the tempered film really scratch-resistant? Can blue light films prevent blue light? What is the principle of anti-peeping film? Is filming all IQ tax? Let’s take a look at
manufacturers say that the screen is very hard, so who hurts it
Nowadays, mobile phone screens are commonly used Corning Gorilla Glass , which was formerly a company that made helicopter front bulletproof glass. This glass is characterized by high hardness, strong scratch resistance, and can reach 7 Mohs hardness! Gorilla Glass has been updated for the sixth generation.
Mohs hardness table (the higher the value, the higher the hardness)
1 talc , graphite , skin (1.5), 2 gypsum, nails (2-2.5), 3 marble, copper, pearls, 4 fluorite , steel (4.5) (knife and key here) , 5 apatite , 6 feldspar , moonstone , 7 quartz, crystal (screen here) , 8 topaz , 9 tungsten steel , ruby, 10 Diamond
So what exactly is it that is both sharp and hard scratching the screen? (There is a foreshadowing here)
has only one truth, it is
inconspicuous in the air - dust & gravel . The main component of dust and gravel is quartz, which can be abused at any time. And don’t think that your phone will not be scratched by gravel if it hasn’t been dropped. It’s more of a small gravel that accidentally enters your pocket.
This is why the phone will always have a few scratches without realizing it.
figured out the reason, and then let’s see if the material of the mobile phone film can resist these damages.
film is not an IQ tax, is the film actually very useful?
has always advocated the function of putting films on the Internet. It is mainly divided into three aspects:
1, scratch-proof: can only change the screen when scratching a mobile phone, which is very cost-effective, and applying a mobile phone film can prevent this situation from happening.
2. Anti-fall: disperses a certain impact force when the screen is impacted, thereby protecting the screen itself.
3, additional functions: anti-blue light, anti-peeping, anti-fingerprint, etc., to make up for the shortcomings of the original screen.
Is the small protective film so powerful? The following are 6 common mobile phone protective films
tempered film
Material: tempered glass
Features: high definition and anti-wear.
Disadvantages: Thicker (which will affect sensitivity), brittle and brittle.
Frosted film
Material: pet film + matte treatment
Features: anti-fingerprint, good feel, non-stick hand, wear-resistant, anti-scratch
Disadvantages: clear 5 degrees .
anti-peeping film
material: pet base material or tempered glass anti-peeping
Features: anti-peeping, anti-glare (anti-reflective), slightly better anti-fingerprint
Disadvantages: low definition (low brightness, color difference), not scratch-resistant
hydrogel film
material: tpu or pet
Features: strong ductility, shock absorption and drop resistance, anti-fingerprint, ultra-thin, automatic repair
material: tpu or pet
Features: strong ductility, shock absorption and drop resistance, anti-fingerprint, ultra-thin, automatic repair
Disadvantages: generally sticky with hands, low hardness, very difficult to paste
anti-blue light film
material: tempered glass
Features: anti-blue light protection eyes
Disadvantages: decreased clarity, color difference, severe reflection
sapphire film
material: sapphire glass
sapphire glass
material: sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire glass
sapphire features: anti-scratch, wear resistance, anti-staining, sensitive feel, good heat conduction Fast cooling
Disadvantages: A piece of film costs 300-500 yuan, (money is not a problem)
Comparison of each parameter
Mohs hardness: sapphire film＞bare metal＞tempered film, blue light film＞proof-peeping film, hydrogel film＞frosted film
Clarity: bare metal＞sapphire film＞tempered film＞hydratized film＞frosted film, anti-peeping film, blue light film
Explosion-proof: sapphire film＞bare metal＞hydratized film＞proof-peeping film＞tempered film, matte film＞blue film
Anti-fingerprint: Frosted film> Hydrosted film> Sapphire film> Bare metal, tempered film, anti-peeping film, blue light film
Feeling: Bare metal> Sapphire film> Frosted film> Tempered film, anti-peeping film, blue light film> Hydrosted film
Anti-blue light: Blue light film> Sapphire film> Frosted film> Bare metal, tempered film, anti-peeping film, hydrogel film
Film difficulty: Tempered film, blue light film, sapphire film <>
film is very useful? Not necessarily, membrane is IQ tax? It is not all that the protective film made of
can indeed play a scratch-proof role, but it depends on the opinions when it comes to anti-fall. As for the so-called additional functions, without exception, they all sacrifice products at the cost of clarity, which makes it a bit more worthwhile.
If you only look at the data: I still recommend sapphire film, all kinds of data are very beautiful, and the hardness is even higher than that of the bare metal screen!
Combined with the actual situation: bare metal is the true love
1. The cost of sapphire film is close to the price of a whole new screen
2. The cost of trial and error is too high: if the film is not well covered, should I buy another film or force the obsessive-compulsive disorder to death? Without the help of a professional testing machine, can I guarantee whether the sapphire film I bought is genuine or a 30-piece tempered film?
