With the release of the iPhone 14 series, the whole mobile phone circle has set off a new round of "replacement wave". But although iPhone is a hot seller, in my opinion, the most profitable person is probably not Cook, but these domestic mobile phone film manufacturers.

The cost of toughened film for mobile phones is low and the profit is high, but there are relatively many brands, and there is not much money for each family. Otherwise, these toughened film manufacturers may have higher profits than Apple.

In just the past few days, many friends around me have changed their mobile phones and asked me if I should use the whole "personality point" toughened film to highlight my "smart island." but to be honest, such a big "pill" is already obvious enough, how can it be highlighted?

In the past two years, there are indeed many "new tricks" in the mobile phone toughened film market, such as anti-peep film, printing film, green film, 36D toughened film. From the point of view of product functions, these toughened films are strange and strange, and the gimmick is far greater than the actual significance. Cutting consumers' leeks is stubble after crop, not soft at all. And many of the mobile phone membranes named by these new terms will have a great impact on the eyes.

Today, I will talk to you about some common mobile phone films on the market, as well as some strange toughened films to protect you from lightning.

"dry eyes" anti-peep film can be said to be a relatively hot film at present, and it can often be seen on the network that someone is promoting such products. This kind of toughened film can be very hot today, to a certain extent, it has something to do with consumers paying more attention to privacy.

Today's anti-peep films generally have an anti-peep angle of 25 °~ 35 °, while some cheap toughened films are lower, about 40 °~ 45 °, which can effectively isolate the peeping of the mobile phone screen.

Photo Source: flash official looks cool, but in fact the principle of anti-peep film is very simple.

When we first see the anti-peep film, we will be very surprised that the film is not white, but similar to black and gray. This is because the anti-peep film adopts a design principle similar to that of shutters.

Image source: from the network blinds by adjusting the angle of each leaf, control the light transmission angle, to achieve a multi-angle anti-peep experience. The anti-peep film is to refine the principle of the shutter, through a "leaf" to cut off the amount of light around the angle, only when the front anti-peep film can see clearly the screen content, in the side view can only see "pitch black", just like this, anti-peep film is generally not particularly thin.

Although the anti-peep film has advantages, but the disadvantages are also very obvious.

First of all, there is the issue of light transmittance. At present, the light transmittance of anti-peep films is only about 50% to 60%. Some high-priced anti-peep films perform better, but the highest is 70%. In other words, if the highest brightness of your phone screen is 1000nit, then after you put on the anti-peep film, the brightness will probably become 600nit.

The engineer's bald head was given an increased brightness, and a toughened film was erased.

In addition, due to the principle of the anti-peep film, there will be grille-like black lines in the toughened film, which also leads to a significant reduction in the resolution of the mobile phone, although it will not make people "blind", but if you use it for a long time, eye fatigue will definitely not run away. Except for some friends engaged in special occupations who may have anti-peep needs, I do not recommend buying anti-peep films.

"720p" scrub film has appeared in the mobile phone circle since the appearance of the toughened film on the mobile phone. After so many years of technical precipitation, the frosted film is still worth affirming. The promotion of frosted film is mainly to prevent fingerprint, anti-oil pollution and anti-reflection.

Frosted film as a common functional protective film in the market, the principle is naturally not complicated, generally speaking, the surface of the ordinary toughened film is covered with a layer of frosted particles, the rougher the surface of the film is, the more obvious the anti-fingerprint effect is.

In the resistance to oil stains, because of the fluidity of water stains and oil stains, fingerprints and oil stains will be dispersed on the surface with high roughness, which is difficult to see with the naked eye.

Picture source: from the network, but it is worth noting that dispersion does not mean no, if some friends are "big oil hands", such as me, after frequent use, they will leave oil marks on the toughened film that are not easy to erase, which will make the screen greasy and feel very bad. It can only be wiped clean with ultra-fine fiber cloth.

Moreover, due to the addition of a frosted particle coating on the toughened film, which leads to light diffuse reflection, which has a great impact on the screen resolution, many friends complain that the whole world is clear after taking off the frosted film.

PS: earlier, I bought a "frosted anti-peep film", the price is not cheap (about 60 yuan), simply refreshed my understanding of the toughened film, frosted film + anti-peep film belongs to the debuff stack, the perfect combination of the two shortcomings in everything, the brightness and resolution are surprisingly low.

I didn't realize the advantage. I almost went blind after a month.

36D "cup" film this kind of toughened film is very hot in some e-commerce platforms, the main hit is cheap, a few yuan, more than ten yuan can buy one, and the introduction of each product is quite exaggerated.

What 8D, 9D, 10D, 99D, 1080D toughened film, people can simply see confused.

Picture source: from the network of this kind of toughened film, also affectionately known by consumers as "cup film".

This kind of toughened film is no different from the ordinary toughened film, which is detached from the early concept of 2.5D arc edge, and then gradually extends to form its own routine.

However, if you want to say the name 4D, I may be able to PUA myself and accept it, but 99D, I can't even fool myself. Is it difficult for this thing to be out of this dimension?

Today, there are only three kinds of toughened films: 2D (straight edge), 2.5D (arc edge) and 3D (curved edge). As long as you make such publicity as 8D and 9D, you can go out and turn right to exit.

This kind of toughened film has been active in Huaqiang North before, and it is often wholesale by some offline film shops and street film stalls at a cost of only a few cents, and it sells at a high price of dozens of yuan.

There is no difference between the product and the ordinary toughened film, because the price is cheap, the sparse oil layer may also face the risk of Jerry-building.

"Photographic yellowing" anti-blue film belongs to the use of physical means to isolate blue light from eye damage. The blue light here refers to a kind of blue visible light with wavelengths between 400 nm and 500 nm, which is very common on electronic screens. The film body of the toughened film is yellow under the white background and reflects blue light in strong light.

Photo Source: from the Internet, there has been a similar discussion about anti-blue film as early as a few years ago, and the conclusion is: useful, but not necessary.

Nowadays, the anti-blue film on the market can not effectively isolate blue light, but only a small part of it. On the contrary, due to the existence of anti-blue film, the screen color will appear serious color bias, and will also reduce the screen brightness and color saturation, long-term viewing will also cause eye fatigue, the loss outweighs the gain.

Anti-blue film Plus: the existence of green film and anti-blue film is the same, both for eye protection, the film is green, there will also be some yellow under the screen.

The purpose of the birth of the green film is "green eye protection". Using the defocusing principle of chlorophyll to prevent the eyeball from being in focus for a long time, the principle is the same as when we relax our eyes and look at green, it will relieve eye pressure. At the same time, toughened film manufacturers will also let it isolate blue-purple light, to achieve the ideal state of "effective eye protection."

Image source: from the network, from the product function, the green film belongs to the "Plus" version of the anti-blue film, on the basis of anti-blue light, but also added some other functions to achieve eye protection.

But note that what I just said is ideal, green film and anti-blue film, can only isolate part of the harmful blue light, the same sentence: useful, but not necessary.

Nowadays, in order to strongly push the green film, some manufacturers compare the anti-blue film, emphasizing the "garbage" of the anti-blue film, which is not as good as the green film. In my opinion, the two are pretty much the same, and even the anti-Blu-ray film is not as effective as the anti-blue film.

As we said just now, the green film belongs to the "Plus" version of the anti-blue film, which naturally inherits its shortcomings. Green film will also cause screen color deviation, reduce brightness, color saturation, and cause eye fatigue.

Strong light is better: AR antireflective film is very hot recently (although I think the reason is that it is expensive, the average price is RMB100,150). This toughened film is the closest to a perfect toughened film among all the toughened films mentioned today.

From the product level, AR antireflective film will not cause eye injury, lower resolution and so on. The principle of AR antireflection film is also not complicated, because the original screen of the phone is not anti-reflective, which makes the screen reflect in strong light, resulting in lack of clarity and brightness in strong light.

AR antireflective film is a toughened film based on the addition of an "anti-reflection coating", so that the screen in strong light to prevent partial reflection, but also with the advantage of a deeper (black) screen.

Picture source: from the network monologue products, AR antireflective film is really good, but because the price is too high, easily 100 yuan, not suitable for everyone, it is more suitable for consumers who often use mobile phones in strong light.

As for the promotion of some manufacturers can increase the clarity, from 720p to 1080p, that is pure deceiving consumers.

"Jerry" Shadow toughened Film this is the toughened film that I am talking about today, which I think is the most outrageous one.

The film body of the shadow toughened film is the same as the ordinary toughened film, which has frosted, high-definition and anti-peep film. The only difference is that the shadow toughened film in the state of the screen, there will be a pattern after direct light shadow, also known as the printing film.

Picture source: from the specific principle of the network, as I personally have not used this kind of toughened film, according to the characteristics of the product, it can be inferred that the pattern part should use a frosted coating with different particle fineness, so as to achieve bright screen transmittance. The function of screen development.

This kind of toughened film pattern is generally based on lovely cartoon images, which can be clearly seen that the main consumers of the products are low-age women.

This kind of toughened film because the audience surface is very small, so the comprehensive performance of the toughened film will not be too high, generally for the "cup film" plus printing, after the purchase of most users will complain about the poor handle of the film, oil thinning layer astringent and so on.

It's not worth buying at all.

From the big spectrum: luminous toughened film earlier I have heard of luminous mobile phone shell, did not expect that even the toughened film is now out of the luminous version, the proper "kill Matt" standard.

This kind of toughened film is to add a circle of "airbag" to the edge of the toughened film. The so-called airbag is a circle of luminous silica gel, which is also called "shatterproof edge". It has to be said that in order to make money, you really don't want face.

Originally, I didn't want to talk about the luminous toughened film, it was nothing strange, but until I saw this.

Image source: from the network night light film: formed by the fusion of the night light film and the shadow film, the night light airbag will emit light in the night, illuminate the shadow printing, and you can enjoy the beauty of cartoons even in the night.

I'm really confused.

Shopping advice: for those who want to buy toughened film, you must remember that don't study the bizarre toughened film every day. After a period of time, you will eventually realize that high-definition film is the destination of mobile phones.

To buy a toughened film, you only need to remember a few points: oil sparse layer, electroplating (electroplating oil layer is better than nano oil layer), toughening grade, thickness, brand, only these parameters are needed to meet your needs, you can rest assured to buy it boldly.

As for the explosion-proof function advertised by mobile phone manufacturers, the toughened film is made of AB glue, even if you want it to break glass.

It's better than anything.
