Is tempered film useful Zhihu, tempered film is a super chicken rib? It must be that you didn t buy

I believe that many friends' mobile phones will be pasted with tempered film, the reason why most people paste tempered film is to prevent scratches on their mobile phones, and at the same time, they may break the mobile phone screen in order to prevent their mobile phones from falling to the ground.

But just from the shatterproof feature of the tempered film, in fact, if the mobile phone falls to the ground, the mobile phone screen is not broken, in fact, it has little to do with the tempered film. I don't know if you have encountered this situation, there is a mobile phone with a tempered film that fell to the ground, and found that the tempered film was not broken, but the screen of the mobile phone was broken. So in fact, the tempered film is known as anti-falling, that is, it reduces the probability of breaking the screen.

From the scratch resistance of the tempered film, the merchants who buy the tempered film generally preach the use of 9h surface hardness, which is the standard of hardness and the Mohs hardness that we often say (Mohs hardness is mainly used in mineral classification. Mohs hardness refers to the ability of minerals to resist wear when they are carved against each other) is actually different, 9h specifically uses a 9h pencil to scratch the surface of the material without leaving a trace, and that's it.

In fact, as long as it is a glass film, the Mohs hardness will not exceed 7, that is, about 5-6, which is larger than metal and smaller than quartz, which means that the general key and knife will definitely not scratch the glass film, which has nothing to do with the surface coating, it will still be worn by quartz (that is, dust and fine particles in daily life).

I believe that when you buy tempered film, you will pay attention to the fact that many merchants' product promotions mention that tempered glass film can prevent fingerprints. The relative price will be a little more expensive, in fact, it is accurate to say that the high-quality tempered glass film can reduce the residue of fingerprints on the glass film, but can not completely eliminate the generation of fingerprints.

In fact, the anti-fingerprint method of the merchant is to add a layer of anti-fingerprint oil to the surface of the tempered glass film, and this layer of anti-fingerprint oil coating can also ensure that the surface of the tempered film can be easily removed when there are stains. Regarding this anti-fingerprint oil treatment process, there are also high and low. Therefore, when buying, you must carefully distinguish between good and bad, and since you buy it, you must buy a good one.

Now most of the current flagship mobile phones are using Gorilla Glass screens, the Mohs hardness of this screen is about about, although it is higher than the general tempered film, if you are in a dusty environment, we said that dust can scratch the screen, so it is more necessary to choose a film, if you don't care much about the mobile phone screen, the strength is enough for your mobile phone to resist most of the scratches, so there is really no need to paste a tempered film.

The main function of the film is to protect the screen from scratches, and it has a certain protective effect when accidentally dropped.

Although it affects the aesthetics and touch, it is not cheap to change a screen. The film is a talisman on the mobile phone, although the effect is not very large, but the heart will get a certain sense of security.

The screen of the mobile phone without film is easy to scratch and become old, and after the film, the mobile phone becomes much newer after changing the film. Nowadays, mobile phone manufacturers generally stick a film when they appear, why? Because although the screen is hard enough, it is still easy to be scratched. Therefore, the film is still very necessary.

How do I choose the right film?

Generally speaking, the original film is the best, although the tempered film is hard, but it is very brittle, and it protects your phone on the surface, but in fact, it will break itself with a little force. If you want to buy a tempered film, don't choose the kind of edge that is easy to empty, and have a good fit of the tempered film, so as to play a protective role.

Tips: If there is a crack on the screen with the tempered film, please tear off the tempered film to judge whether the screen is broken, or you can see whether the screen is cracked from the edge of the cracked tempered film. Some people have been pitted, the tempered film is broken, it is said that the screen is broken, and the so-called "vacuum nano coating" on the street is fake!

It's not shatterproof at all, and smashing walnuts is also crispy walnuts, which is the "emperor's new clothes", don't be fooled.

In general, the mobile phone film is still very necessary, which can protect the mobile phone screen from being scratched, and to a certain extent, it can protect the mobile phone from being broken by the screen, and it will still break if the force is too large. While bare metal feels better, it's necessary for most people. After all, it is expensive to change the screen and change the phone.

1. The biggest role of the tempered film is to protect the glass of the mobile phone screen, because the current mobile phones are using full lamination technology, so the glass damage replacement needs to replace the entire screen, compared with a mobile phone film, the ** is much higher, and the impact resistance of the plastic film is not as good as the tempered film;

2. The thickness of the tempered film protective layer is only millimeters, which can completely cover the original screen surface, prevent damage and scratches by external forces, and increase the impact absorption, which is 5 times higher than the standard of PET film. The surface of this film is hard enough to scratch hard, even if you scratch it with a knife, it will not get flowers, because the hardness of iron is lower than that of glass;

3. It is easy to use and does not bubble. The light transmittance of the picture is as high as 98%. It does not affect the use of mobile phone cases and other mobile phone accessories.

If you are satisfied, thank you.

If you don't change your phone often, or paste a tempered film, not only can protect the screen from being scratched, but also accidentally fall to the ground, the basic mobile phone screen will not hurt, if there is a mobile phone case, the basic mobile phone will be used for a year or two, or the same as the new one, even if you change to a new mobile phone in the future, the old mobile phone will be much higher because of proper storage.

It must be useful.,At least the screen won't be hung up if the tempered film is pasted.,The protective screen must be pasted with a tempered film.,Some people don't want to stick it and say that it affects the feel I want to say that ordinary people can't feel any impact at all.,Unless a good player says otherwise.,There are many benefits to pasting.。

Tempered film is useful, it is recommended that you use tempered film to prevent falls.

It doesn't work, and the disadvantages outweigh the benefits.

The film on the mobile phone will affect the heat dissipation of the mobile phone, the mobile phone screen is the main position of the mobile phone heat dissipation, if the mobile phone can not dissipate heat in time, the performance will be greatly reduced.

Step 2 2 If the phone fails to dissipate heat for a long time, it will also cause a series of problems in the phone.

After the mobile phone is filmed, it will affect the light transmittance and light transmission uniformity of the mobile phone screen, which will make the display effect of the mobile phone screen worse, thus affecting the eyes.

Step 2 2 In addition, the mobile phone film will also affect the reflectivity of the screen, and looking at the mobile phone screen outdoors with strong light will cause great damage to the eyes.

The advantage is that it can protect the mobile phone screen, and the disadvantage is that the film will cause some damage to our eyes.

As a hand-skating party, I have also become a mobile phone film enthusiast because of this. I have used a variety of big brands, small manufacturers of mobile phone film, especially tempered film, the result is that the big brand of mobile phone film may not be the best, although the products produced by small manufacturers are inferior, but the heart can still find good goods. What kind of mobile phone film to choose, you have to rely on your own vision.

I have used so many large and small tempered branches, but it is difficult to have a product that is satisfactory in every place. It wasn't until I used this phone film that I regretted it so much, how good it would have been if I had come across this phone film earlier, because it was so easy to use! How good is it to use?

Tempered film. This tempered film is made of a strengthened version of the tempered material, so in terms of drop resistance, it is much better than the general tempered film. I have also done experiments, maintaining the same strength with a hammer to hit the ordinary tempered film and this tempered film, the ordinary tempered film has obvious cavity clump cracks, but this tempered film is unharmed.

It can be seen that its anti-drop performance is very good, and it is perfect for a hand skater like me.

In addition to its excellent anti-drop performance, there is another thing that appeals to me about this phone film, which is the anti-fingerprint ability of its oleophobic coating.

Tempered film. Do you know why the mobile phone feels so smooth when you first buy it, but after using it for a long time, the screen begins to become insensitive? It is because the fingerprint oil coating on the surface of the mobile phone screen is slowly disappearing.

Sowu orange is now that many mobile phone films will be added with oleophobic coatings to restore the feel of the mobile phone screen as new.

However, don't assume that smooth is good. The most important thing to look at is the wear resistance and durability of the oleophobic coating. I bought a lot of mobile phone films, and it turned out that most of them felt very smooth at first, and I could play games as much as I wanted.

As fast as the fingers move, the characters move as quickly as they do. But after a month or two, the smoothness of these mobile phone films has decreased significantly. But this mobile phone film does not have such a phenomenon, after a long period of use, the feel of the screen is still very smooth, like new.

Tempered film. In addition, the automatic adsorption function is also a highlight of this mobile phone film.

For a lazy person like me, I am too lazy to go out and spend money to hire someone to apply a film. But I posted it at home, but it was always imperfect. Many tempered films only give you one chance to apply the film, and they will be scrapped if they are not pasted.

But every time I put on the film, it is either crooked, or there will be small bubbles or small white spots.

Tempered film. However, this mobile phone film is different from ordinary film, it can achieve automatic adsorption. Just align it with the hole in the phone screen, let go of it, and it will stick tightly to the screen.

In addition to saving time, this adsorption method also has the advantage that there will be no unsightly bubbles and white edges. Make the OCD person look satisfied.

I have heard many friends complain: the imitation and chemical film of steel tung is too chicken! It's not safe to stick the film, but after the film, I found that it was useless, and even the mobile phone screen was broken, but the tempered film was still intact!

Is tempered film really just a new marketing product launched by merchants in order to make huge profits? Of course not. A good tempered film can not only be anti-fall, but also have the functions of anti-slip, dust-proof, anti-fingerprint and so on.

If you think that the mobile phone film you are using now is useless, then you should first think: did you not buy a good product?

Tempered film. Tempered film, as soon as you hear the name, you know that it is full of hardness, and it is used to prevent the phone from breaking. However, there are some mobile phone films on the market, but they can't protect the mobile phone screen at all.

The phone fell to the ground, but sacrificed the screen to protect itself, and in the end, the membrane was unharmed, and the screen shattered to a mess. There are two reasons for this phenomenon: the first is because the material of the tempered film is relatively cheap; The second point is that the film is not applied correctly.

First of all, let's talk about the material of the mobile phone film. There are many types of mobile phone film materials: PP, PVC, PET, glass, etc.

If you want to buy a tempered film with significant anti-drop function, then glass material is the most suitable. However, there are also a lot of exquisiteness about glass materials, and the effect of inferior glass film is not even as good as plastic. At present, the top companies are SCHOTT in Germany, Corning in the United States, AGC in Japan and so on.

The Asahi glass produced by the Japanese AGC Group is one of the top glasses in the world, which is very durable and suitable for tempered film.

However, if you apply the film yourself, you will often encounter the problem of uneven application and bubbles. This kind of small problem does not affect the use, so many people ignore it. However, once the tempered film is uneven, then its anti-drop effect will be greatly reduced.

Therefore, I recommend everyone to use a tempered film with automatic adsorption function. Just align the hole and put it gently, and the mobile phone film can be adsorbed on the screen by itself, which not only saves you the trouble of sticking the film, but also does not bury potential safety hazards.

Tempered film. In addition to the anti-drop function, a good tempered film can also be anti-fingerprint. Some mobile phone films will use the anti-fingerprint oil coating of Merck KGaA, Germany, to prevent fingerprints and sweat stains from being printed on the screen, which greatly improves the cleanliness of the mobile phone screen and benefits the cleanliness family.

Regarding the sensitivity of the screen, the high-quality tempered film will not be ignored. Many people will find that when playing games, the mobile phone response is much slower and they can't keep up with the hand speed. The main reason is that the mobile phone film is too thick in order to play a role in preventing falls.

However, high-quality tempered film tends to have a moderate thickness, so playing games on the machine will not cause the problem of operation delay. For boys who love to play games, they must carefully choose a good quality tempered film.

Tempered film.

Mobile phone tempered protective film is commonly known as explosion-proof film, and the tempered film structure has 5 layers of PET release film + silicone glue + PET substrate + OCA optical adhesive + PET release film.

The mobile phone tempered film is an extra-thin film made of tempered glass, which has the functions of anti-wear and explosion-proof. That is, ordinary glass is tempered. Generally speaking, sticking a tempered film can really prevent the mobile phone display from breaking, but it can't prevent the breakage caused by side collisions, that is, knocking the corners of the mobile phone.

There is a chance to shatter. The structure is that the glass is tempered. So which brand is better to buy tempered film?

On the whole, the tempered film of the two brands of Aigostar and Lianglong is better.

When you buy a new mobile phone, he needs a tempered film for each mobile phone. When you don't use tempered film anymore, you will be particularly distressed if you break your phone, so you should use tempered film. However, if you apply the film at the mobile phone store, it will be a little more expensive than buying it yourself.

So many people will buy tempered film online. I have also used many brands of tempered films, such as Aigostar, Pinsheng, Mingcai, and Lianglong. Below I want to recommend a few tempered films that I think are cost-effective.

1. Patriots.

Most of his tempered film types are full-screen covered and have a strong thickness. The handicap party is also very easy to get started. And anti-fingerprint, fingerprints are difficult to stick to the screen.

There are other types of it, such as anti-blue light ones that can prevent myopia and better protect your eyes. This tempered film is the one I said I have used for the longest time. He can be said to be very practical and cost-effective.

This tempered film will not let your hands out of contact with the screen. It can be said that he is very touchable.

2. Bright Dragon. Most of the brands of this brand are tempered films that are anti-blue light. Sometimes I feel that my eyes are very tired when I look at my phone, and there is no harm in using anti-blue light tempered film.

This brand's true anti-blue light tempered film can block 90% of the harm of mobile phones to the eyes. With this anti-blue light tempered film, you can look at your phone like a book. It has a smooth feel, is dirt-resistant and wear-resistant.

In summary, the first tempered film can be cost-effective. The other one is very worthy of the student party and those who insist on playing mobile phones to buy. These two tempered films are also very reasonable.

The quality is also very good, the screen display should be clear and feel smooth. It is all designed with full screen and no dead ends. But their only feature is that one is not blue light protection, and the other is not blue light protection, so it depends on your needs to buy it.
