With the rapid development of smart phones, some third-party accessories also ignited. Mobile phone film is one of them. Especially during the Spring Festival, the boom of user replacement has once again arisen. After getting the year-end award, it will always be for themselves or around them. The first thing a lot of people do after purchasing a mobile phone is to give the love machine a sticker. However, for so many years, have you really posted it?
Those who promote XX black technology, anti-explosion explosion-proof mobile phone film really practical? Hundreds of mobile phone film must be more than a few cents of the mobile phone film is more easy to use? Do not worry, after reading this article I read for you one by one.
This should not be a film on mobile phone. This is a problem left over from history. In addition to the functional machine era, we will not choose the foil. After all, there will be no large-screen mobile phone and no more maintenance costs.
But now full screen mobile phone hot, bigger and bigger screen, the material is getting better and better maintenance more and more expensive, many people think of 'paste a safe and secure film', but you really think it useful, in fact, more Are a kind of self psychological hint, practicality? No!
A few days ago, suddenly found on the Internet called 'Hydrophilic Film' mobile phone film, that promotional video, that parameter is simply the phone in the fighter film ah, a variety of so-called black technology after another, with 'knowledge 'Psychology, I found a sales volume in front of a business to buy.
Top sales list of a 'water film' businesses
To be honest, after getting the hand I feel that there is not any substantive thing, that is a plastic film, had to sigh a wave of powerful force.
As the phone has been affixed to the film, all the photos of what I have no way according to the photos, so we forgive me. For me to say my feelings, the hydrosolvent in the end okay.
I have regretted to open the hydrogel film packaging, a thin layer of plastic, with a tube of 'foil water' and then is the phone foil tutorial, the film of water sprayed on the membrane to make it moist softening, and then posted on the phone press 15 minute.
If you do not start easily do not try, one of the difficulties is not one or two sentences can be summed up, obviously has wiped the screen, obviously no bubbles, stick for a while you will find the bubble out, how to clean up all clean Clean, special trouble. Let me say that with the bottle of film water, what is the use? In summary is the screen and the film material has a sticky, with the water after the foil can be easy to shift stickers.
Looked back at the propaganda of those businesses: explosion-proof, drop, feel good, I thought for a moment, think this is a shit.
Explosion-proof drop? Hydrophobic film really explosion-proof drop, after all, is how a plastic may fall bad, but the phone screen is not ah! This is the clever business place. Feel good? Reason ibid, thin plastic almost contact with us The screen has no effect, of course, feel good.And those written in the copywriting of all new 'black technology' to fool people still, spend money to buy a music Oh.
Oh right, then I bought this piece of coagulation film to a bad review, the results of customer service directly to find that I give the money back to you, I said OK, but the phone can not give you the film to throw back, customer service Say no need to retired ... Keke cough, probably from the dialogue can also see this 'hydrosolvent' industry in the end more money now.
After this incident, I found a lot of information and found that this 'black technology' was not actually included by Baidu Encyclopedia, Wikipedia, etc., which has actually revealed that this is a scam solution, if it is a technological invention, Encyclopedia can not be included, the patent inquiries, there is no patent on the hydrogel membrane.
So, 'Hydrophilic film' this so-called new technology cell phone film is not used, no difference with the ordinary film, we look like, not practical.
Mobile phone foil is roughly divided into these types have used it
Speaking of mobile phone film, we can think of it is too much, what high-definition light-transmissive film, tempered film, nano explosion-proof film, etc. Next we take a look at the current mobile phone market, those common mobile phone film, Estimated how can you have used a paragraph.
Hydrophilic film
The first thing to say is that we mentioned above the hydrogel membrane, the material of the hydrogel membrane is generally tpu or pet, a detailed explanation does not say, the general meaning is that these two materials are relatively low prices, and oil, Water resistance, mold resistance, carrying capacity, impact resistance and shock absorption are outstanding.However, tpu posted a serious grainy (phone shell soft shell mostly for this material), pet material is slightly harder.
Of course, in addition there are some unscrupulous traders will choose a material called PP, PP material generally refers to polypropylene, on October 27, 2017, the World Health Organization International Agency for Research on Cancer released carcinogenic Initial inventory of the list of references, polypropylene in the list of three carcinogens, the cost of this material is cheaper, the retail price may be a few cents, but sold out if you can sell 50 +.
Of course, this is not the most pit, the most pit is that this material made of the hydrosoluble film if attached to the phone screen will seriously corrode the screen, your high-end 2K screen will become 720.
Steel film
Toughened film be more conscientious in recent years, mobile phone foil, and some people say that the first development of the country, and some people say that the United States first developed, these issues are not the focus of our discussion today. Thickness of only 0.1 mm, the original screen can be completely covered to prevent damage by external forces, scratches, but also increase the impact absorption, PET film than the standard high 5 times, will not affect the screen video effect.
Phone tempered membrane market is more popular and more mainstream, but because of the market circulation, user demand is high, the major manufacturers are also fancy business opportunities have to join them.More manufacturers will gradually evolve into vicious competition, the second Well filled, the last loss or our users.
Nano-film
If the hydrogel film is a relatively pit thing, then the nano-film is the world's most pit .Net promotional video we should have seen, cell phone on the table, labeled 'nano explosion-proof membrane' Hammer smashed it all is fake, if there is such a material, there Corning Gorilla what happened?
Of course, it can not kill a stick, the real practical nano-film or there will be, here to avoid aversion not to say the brand.
Many of the domestic nano-explosion-proof membranes are just an upgraded version of the previous HD-PET membranes, and the explosion-proof effect is not very different from that of ordinary HD membranes. Not to mention the video is as good as it is in the video. The videos we see, In fact, after many mobile phone screens are dismantled, the toughened glass (or bullet-proof glass) or prototype is installed.
Anti-Blu-ray film
This is also a kind of mobile phone film that has become popular in recent years. Everyone thinks about Blu-ray's worry. We should blame the advancement of science and technology for our recognition. The large amount of blue light in the light may cause damage to the retina. Blue light intensity has a special limit
In addition, long-term exposure to blue light may have some impact on our endocrine, immune hormones, etc. So, anti-blue film came into being.However, do you really think anti-blue film is all effective?
For anti-blue film test (images from the network)
Not long ago, there was a special anti-blue cell phone tested for Blu-ray film resistance, even on the day of the test also used our home cling film as a reference object, the actual test results show that, with or without cell phone membrane, grade 0, strength far less than the standard limits, are non-hazardous category. phone screen generated by the blue light damage to the retina that point is very low, as to how to avoid hazards Blu-ray, the only way is less at night to play phone.
HD translucent film
This film is simply a sentence just fine, practicality is relatively strong, cheap average screen a few cents, a few dollars you can buy, there is no harm, the advantage is that it can scratch and can often change for not distressed.
Said so long, mobile phone foil really useful? You listen to me to you.
The screen is not so fragile foil is not necessarily easy to use
Finished so many cell phone foil, I think a small problem, our cell phone screen really so bad? Do not foil the same as will Huaping? I intend from a professional point of view to tell you a little dry goods, cell phone stickers actually is Figure a comfortable heart, in fact, your own heart certainly know that cell phone membrane really useless.
Is the phone screen really awkward?
The current mainstream flagship handset makers generally use Corning gorilla glass and sapphire glass screens on their handsets, both of which have excellent screens with Mohs' hardness of even 9. The hardness of 9 can threaten it Already very few, ordinary keys or even knives, it will not leave traces.
The hardness of 10 diamonds, I believe no one will use diamonds to scratch the phone, want to have a diamond scraping, but then again, you use a diamond scraper mobile phone?
Of course, there is no absolute thing, in addition to the diamond there is a special case, jumped out of the Three Realms is not in the five elements, that is sand. Sand contains emery, the hardness is also the existence of 10 levels, if you are in a dark environment more sand flying , Of course, need to stick a film to resist, but in addition it is really unnecessary.
Moh's hardness
Take a look at this form we should understand that the cell phone membrane may be less than the phone screen itself can easily resist. You really do not believe that earlier this year, there have been media tests done in this area, let's The truth.
Testers chose the HTC U Ultra for $ 50 and sapphire (HTC U Ultra fifth-generation Corning Gorilla Glass). Surprisingly, cell phone stickers up to $ 50 hang up early However, HTC U Ultra has persisted to the end.
Mobile phone film Mohs hardness of 3 appeared on the scratch (picture from abroad)
HTC U Ultra has been strong until the Mohs hardness scratches 8 (the picture from foreign media)
Why is the most practical steel film?
Talking about practicality, everyone may have everyone's argument, but let me recommend it, I choose the tempered film. Hard enough to really resist some of the phone screen damage, these are not soft membrane can do (probably I have never seen), but, indeed, the phone's drop resistance has some protection, but also scoring conditions.
Now let me talk about the common situation of mobile phone broken screen, generally divided into four kinds, respectively, broken screen is good, screen broken screen, screen good film, screen broken screen is good.
Film broken screen is good Description of mobile phones by the impact of impact than the membrane can withstand the impact of less than the screen can withstand, so the film broken.
Broken screen broken pieces Description of the impact of the phone is greater than the sum of the screen and film can withstand the impact, so both are broken.
Screen good film Note that the impact of mobile phones received less than the screen and membrane can withstand the impact, so no broken.
Screen broken film is good This situation is rather special, it is because the problem of throwing the point so the impact of the film to withstand smaller, all the impact on the screen so the screen broken film is good.
Mobile phone foil can really protect some of the basic daily scratches, but if you want to explosion-proof, drop is completely impossible. More may be a psychological comfort, psychological suggestion.
Again, Jobs hard to thin the phone to make thin and thin, who just arrived in the country to be affixed to the user cell phone membrane, posted a thin protective nothing, affixed to the thick feel does not say Also make the phone look ugly, in fact, really needless.
I remember a word that is very good: Streaking is a respect for cellphone designers Can not always get a cell phone from hand to eliminate have not experienced the real pure feel it, take my own example, Samsung S8 has streaked for 8 months so far, the phone screen is still intact. The tangled classmates I can tell you clearly, the phone screen is not so fragile, the film is not much effect.
Want to protect your cell phone screen I give you a trick
Having said that, I believe we have a general understanding of the hardness of the phone screen in their hands, there are a variety of mobile phone foil can see who is useful who useless. Then I will support for everyone A move, how to protect your cell phone screen.
How to buy a flagship phone
Flagship mobile phone will prove that it will certainly be expensive, not only the price is expensive, maintenance is expensive outrageous. Take the iPhone X for example, the screen is not broken a small sum of money, enough to be an Android flagship So what is the first thing after buying a cell phone?
About broken screen insurance We still use the iPhone X to give examples (except iPhone X, Samsung, Huawei and so on), buy broken screen insurance AppleCare + iPhone X screen repair cost is 188 yuan, but did not purchase is 2278 yuan While the general flagship phone screen repair costs are basically hundreds or thousands of dollars, this time you know the importance of broken screen insurance it.
Another point to add that the flagship phone's screen quality is far more than the average cell phone can be compared, and, even if you affixed to the film is also broken the broken.Of course, there are people who will say that the film is also scratch-resistant ah, In actual fact, unless you have a cell phone into the sandstorm, or you buy a flagship phone is not the real flagship phone, otherwise there will be no such situation.
What should I do if I buy a non-flagship phone?
Not the flagship phone is certainly not the best configuration, probably the flagship phone using Corning Generation 5 gorillas, and these phones can only use a Corning 3 generation. But despite this, that is not to say that the hardness can scratch the scratch, so there is no need to foil, if you have to find peace of mind, I suggest you spend a few cents to buy a regular phone film enough.
If you want to drop better to buy phone case, at least you can also protect the four corners are not wrestling deformation.
Believe that this will certainly have a small partner to refute .For example, 4.5 hardness of the things wrapped in 5.5 hardness things, hit 5.0 hardness, 4.5 completely scrapped, but even if there is no 4.5 package 5.5 things as normal , So that we understand it.
If you have to buy a cell phone film, then I recommend the ordinary film> Tempering film> the rest of the mess of film with the continuous development of science and technology, mobile phones have become essential to everyone, if it is really necessary, the factory When the merchant will give you a cell phone film installed, we say right. For your feeling for your experience, take off that layer of thin mobile phone film it.
