The issue of cell phones should not be filming has been controversial for many years by machine friends, even though manufacturers continue to enhance the durability of glass, but still can not stop consumers beloved cell phone affixed to the cell phone membrane determination.
And once you choose the film, it will certainly have to spend time to pick a satisfactory mobile phone film in the full screen and 2.5D glass prevailing today, buy mobile phone film is not the year 'choice HD or matte' that simple Problem.
Hydrophilic film? Tempering film?
On the market of mobile phone film, nothing more than two categories: one is represented by the plastic film hydration film, the second is represented by the tempered glass film all the two films have different titles And variants, but the actual difference between plastic film and glass film.
but, Hydrophilic film and plastic film in the past there are some differences, this mobile phone film thinner and softer, good ductility , In the screen surface of the cell phone can fit well, but also have some small scratch self-healing ability (but also limited)
Hydrophilic film
Hydrophilic film is a kind of plastic film, but the texture is softer than the traditional plastic film, the fit performance is better.People used to spray some products past, and now many hydrogel films do not need this step, so it has nothing to do with the water But the essence is also a hydrogel membrane.
Hydrophilic film compared to the tempered film, the biggest advantage is that it can perfectly fit the phone screen, so the surface screen and 2.5D screen was born, gradually emerge, by many users.
However, the plastic film, after all, is in the hardness, transmittance, scratch-resistant wear performance and certainly not comparable to the tempered film. Some businesses say that the coagulation film falls off is not a piece of steel on its advantages, which are entirely nonsense, of course, plastic film is not broken.
In addition, due to the relatively soft, so difficult to paste the hydropic film is relatively high, there will be bubble paste bad, the use of this film requires more patience.
Steel film
Toughened film is the use of tempered glass cell phone film, mainly divided into full coverage and non-full coverage of two types.As the name implies, full coverage refers to cover the screen display section and the frame of the tempered film instead of full coverage of the tempered film usually only Cover the screen display section and the upper and lower part of the border.
The reason why the tempered film has full coverage and non-full coverage, mainly because most of the handset will be 2.5D arc to deal with the screen edge transition, and the glass itself is not easy to bend, not close to the arc part, so manufacturers Select the launch of the screen part of the glass material, surrounded by plastic and other materials, full coverage of the tempered film.Now there are some full-glass full coverage of the tempered film.
The biggest advantage of the tempered film is natural feel, but also high hardness, not prone to scratches, good protection. And the glass itself is better than the plastic light-transmissive, the perception will be closer to the film than the plastic film state.
However, whether it is full coverage or non-full coverage, the biggest problem of the tempered film is still not close enough, the less accurate precision tempered film will appear white edge problem, which will result in fouling over a long period of time. .
In addition, the poor quality of the tempered film foil edge or the middle of the screen if not close to the screen, at some angles will appear rainbow lines, the perception will be greatly affected.
Serious white edges, and rainbow stripes around white borders
As for whether full coverage or non-full coverage should be selected, I think the main problem is seeing who is pleasing to the eye. The protection of a full-coverage film on a screen is also a drop in the bucket. Drop-proof is basically a well-protected mobile phone case.
Which selling points deserve attention, which are flicker?
9H hardness? Big flicker!
9H hardness is a very fan of the propaganda point, reasonable, there is no steel up to 9H hardness standard manufacturers 9H mouth hardness actually refers to the pencil hardness level, and we evaluate the hardness of glass, the general use of Mohs Hardness (Mohs hardness) standard.
Glass Mohs hardness of 6.5, higher than copper and steel, so the general key and chopper is no way to leave a scratch on the screen of the cell phone, but the quartz Mohs hardness of 7, we are also very easy to come into contact with To (small sand), the thin scratches that the cell phone streaks for a long time are actually the fine sand and dust in the pocket and the bag.
Anti-Blu-ray? Big flicker!
Regardless of the effect of anti-blue-light toughened film, most mobile phones have night mode (or similar function can be achieved through third-party apps). The screen of the mobile phone will adjust the color temperature to reduce the blue light. Therefore, many types of mobile phones do not need extra anti-blue light Measures.
So, instead of adding money to buy with anti-Blu-ray mobile phone film, might as well reduce the phone brightness, reduce the use of mobile phones, or enable night mode to be practical.
Anti-peep film? Best not to buy!
There are some anti-seepage products on the market, which can prevent darkening of the screen by blocking certain angles of light, but such products will make the screen darker, Certainly affected.

Screen brightness is not darker the better, when the light is too dark, we need more attention and closer distance to see the screen content, in fact, the eyes are more unfavorable, so the appropriate brightness is very important. There are businesses will To put anti-seepage film marked eye protection, apparently nonsense.
Oilslip? Necessary!
Oleophobic also known as oleophobic coating is a composite coating material that can increase the hydrophobic hydrophobic properties of the screen can play a certain anti-fingerprint effect, but also the oil-repellent surface of the screen better clean.
However, the film after the oleophobic layer can only be covered by the phone membrane, it is also recommended that you buy the oleophobic layer of the tempered film.In addition, to determine the mobile phone screen or tempered film is not oleophobic, just drop a drop of water on the glass, if the water droplets Condensed into circular droplets, it shows that the oleophobic layer.
Mobile phone membrane there are many small details, such as the glass did not mention the original film, although Corning, AGC, Schott and other imported glass products of good quality, but it is difficult to judge the authenticity.
Some people say that these imports of precision glass bending resistance, and even can be folded, but the problem is to buy the back of the bending test to do the film, the result is not dumb to eat Coptas? Therefore, in general, consumers do not have this test conditions, We also think there is no need to be too obsessed with these imported glass (of course, the target price can be compared with these key words).
