Hydrogel and tempered film which is better? Cell phone film originally had these knowledge



The question of whether or not mobile phones should be filmed has been debated by machine-friends for many years. Even if manufacturers continue to improve the durability of mobile phone glass, they are still unable to stop consumers’ determination to attach a mobile phone film to their favorite mobile phones.


Once a film is selected, it will definitely take time to pick a satisfactory mobile phone film. With the prevalence of full-screen and 2.5D glass, buying a mobile phone film is no longer a simple matter of choosing high-definition or matte.

Hydrogel film? Tempered film?


As for the mobile phone membrane on the market, there are two major categories: one is a plastic film represented by a hydrogel film, and the other is a glass film represented by a tempered film. Both cell phone membranes have different titles and variants, but they are actually the difference between plastic membranes and glass membranes.


However, there are some differences between the hydrogel film and the plastic film in the past. The film is thinner, softer, and has good ductility. It fits perfectly on the mobile phone with a curved screen, and it has a certain self on the small scratches. Repair ability. (However, it is also limited)


Hydrogel film


Hydrogel film is a kind of plastic film, but the texture is softer than traditional plastic film, and the fitting performance is better. In the past, some products needed to be sprayed with water. Now many hydrogel films do not require this step, so they have nothing to do with water, but the nature is also a hydrogel film.


Compared with the tempered film, the hydrogel film has the biggest advantage that it can perfectly fit the mobile phone screen, so after the birth of the curved screen and the 2.5D screen, it gradually emerged and was welcomed by many users.

However, the hydrogel film is, after all, a plastic film, which is certainly not comparable to a tempered film in terms of hardness, transparency, scratch resistance and wear resistance. Some businesses say that the hydraulic film is not shattered is a major advantage for the tempered film, which is totally nonsense, of course, the plastic film is not broken.


In addition, because it is relatively soft, the difficulty of sticking the hydrogel film is also high, and there are bubbles when the adhesive film is not good, and more patience is required when using this film.


Tempered film


Tempered film is a mobile phone film made of tempered glass, which is mainly divided into two types: full coverage and non-full coverage. As the name suggests, full coverage refers to the ability to cover a tempered film that includes the screen display portion and the bezel, while a non-fully covered tempered film typically covers only the screen display portion and the upper and lower portion borders.


The reason why the steel film has full coverage and incomplete coverage is mainly because most of the current mobile phones will use a 2.5D arc surface to deal with the screen edge transition, and the glass itself is not easy to bend and can not closely fit the arc surface, so the manufacturers Select the full-covered tempered membrane with glass material and surrounded by plastic and other materials. There are also some full-glass full-covered tempered membranes.

The biggest advantage of tempered film is that it feels natural, and it has high hardness. It is not prone to scratches and has good protection. In addition, the glass itself is more transparent than plastic, and the appearance of the glass is closer to that of the film than the plastic film.


However, whether it is full coverage or partial coverage, the biggest problem with tempered film is that it is not tightly laminated, and the steel film with poor accuracy will have white border problems, and it will accumulate ash when used for a long time, which will impair the protective effect. .


In addition, if the edge of the tempered film film with poor quality or the middle of the screen is not close to the screen, rainbow patterns will appear at certain angles, and the perception will be greatly affected.

As to whether full or partial coverage should be selected, I think the main issue is to see who is pleasing to the eye. The protection of the screen by full-coverage film is also a drop in the bucket.


Which selling points are worth paying attention to and what are the big flickers?


9H hardness? Flicker!


9H hardness is a very publicity point, reasoned, there is no tempered film up to 9H hardness standards. The 9H hardness in the mouth of a manufacturer actually refers to the hardness grade of the pencil, and we evaluate the hardness of the glass, and generally use the Mohs hardness (Mohs hardness) standard.

The Mohs hardness of the glass is 6.5, which is higher than that of copper and steel. Therefore, the key and the kitchen knife are generally not able to leave scratches on the screen of the mobile phone.

However, the Mohs hardness of quartz is 7, we are also very easy to access (fine sand) everyday, the fine scratches that the mobile phone is streaking for a long time is actually the fine sand and dust in the pocket and bag.


Anti-blue light? Flicker!


Regardless of the effect of anti-blue tempered film, most mobile phones currently have a night mode (or can achieve similar functions through a third-party app). The mobile phone screen will adjust the color temperature to reduce the blue light, so many models of mobile phones do not actually need extra anti-blue light. Measures.

Therefore, instead of adding money to buy a mobile phone film with anti-blue light, it is better to reduce the brightness of the mobile phone, reduce the time for using the mobile phone, or enable the night mode to be practical.


Anti Privacy film? Best not to buy!


At present, there are some anti-peeping products on the market, which can achieve the anti-peeping function of dimming when looking at the screen by blocking light at a certain angle. However, this kind of product will make the screen very dark, and it will have some impact on the battery life and vision.

The brightness of the screen is not as dark as possible. When the light is too dark, we need more attention and closer distances to see the screen content. In fact, it is more unfavorable to the eyes, so the appropriate brightness is very important. At present, some businesses will put a protective eye mask on the privacy film, apparently out of nothing.


Oleophobic layer? Is necessary!


The oleophobic layer, also called oleophobic coating, is a kind of composite coating material, which can increase the oleophobic and hydrophobic properties of the screen, and can play a certain anti-fingerprint effect, and the screen surface of the oleophobic layer is better cleaned.


However, the oleophobic layer after the film can only be covered by the mobile phone film, so it is also recommended that you buy a tempered film with an oleophobic layer. In addition, to determine whether there is an oleophobic layer on the mobile phone screen or the tempered film, just drop a drop of water on top of the glass. If the water droplets condense into a circular drop, there is an oleophobic layer.

There are many small details of the mobile phone film, such as the original glass film not mentioned, although it is said that the quality of the glass of imported products such as Corning, AGC, and SCHOTT is good, but it is also difficult to judge the authenticity.


Some people say that these imported precision glass are bent and even folded, but the problem is to buy a steel film back and bend it to do the test, the result is not dumb to eat Coptis? Therefore, the average consumer actually does not have such a test condition, and we also think that there is no need to stick too much to these imported glass (of course, these keywords can be compared at the target price).
