How to distinguish the quality of tempered film? How to tell if the tempered film is broken

For frequent changes in tempered film.

Xiao Ke said, he summarized some methods to compare good and bad tempered films.

The easiest way is to ask people if they are glued on the whole screen when you change the tempered film, or if only the four sides are sticky.

If he says it's the all-adhesive kind, you'd better not change it, because this tempered film is the worst.

How bad it is, if you touch the table a little bit, or on the floor, it will crack, and if it falls to the ground fifty centimeters high, it will be absolutely completely cracked.

I don't know why it's so small, but I've used two of these all-sticky ones myself, and this is the case, but this will be cheaper.

And whenever you break it and go to change the screen, people will say that this is the worst, and it is easy to stick the screen of your mobile phone.

And the kind of tempered film that sticks around it, of course, sounds like it is not fully sticky and resistant to falling, but in fact, people are quite resistant to falling, just small and replaceable, and no longer afraid of children taking their mobile phones to listen to songs and play, because Xiao Ke knows that the screen inside is not broken, and the tempered film outside is not so easy to break.

If you break it and replace it, it's also quite easy, and you can drop it as soon as you remove it.

Therefore, if you change the tempered film, you can ask whether it is fully adhesive or surrounded by adhesive film.

As mobile phones become more and more popular, we also have some requirements for many accessories for mobile phones. The mobile phone screen is also particularly fragile, and it is easy to crack when it is often dropped. At this time, the mobile phone tempered film plays a role.

The quality of the mobile phone tempered film is judged according to some of his characteristics. <>

First of all, you can see the quality of the tempered film through its material. In general, the inferior one is the tempered film of glass. Such membranes also tend to be fragile.

It is easy to shatter and crack. When we buy tempered film, we must look at its material in the details.

Secondly, there are also some tempered films that are synthesized with some PC substances. These tempered films are stronger than those of glass. But he's not very good for our feel. When playing a game, my hand sweats and is easy to rub against a membrane.

Finally, I would like to say that the best tempered film should contain metal. Such a tempered film is not only strong, but also feels good. For some people who have a high quality of life, this tempered film is more suitable for their choice.

When choosing a tempered film, first look at whether the tempered film is pure and flawless, and don't buy it if the film is dirty and flawed.

Then put the tempered film on the screen of the mobile phone, and see through the film whether the color change is serious or not. Some of the original mobile phone display screen shows that there is basically no color difference, and the tempered film can be pasted on the serious color difference, indicating that the quality of the tempered film is too poor. <>

Put the tempered film on the mobile phone to compare and see if the size matches the size of your mobile phone display. Check the tempered film horizontally and vertically to see if there is a radian, and the tempered film with a radian that is not on the same horizontal plane will be unsuitable when pasted on the mobile phone. Such a tempered film is relatively easy to break, and it is easy to get into dirt such as dust inside.

Look at the thickness of the tempered film, too thick will affect the sensitivity of the touch screen, too thin will have quality problems, the purchase of tempered film, it is best to be around.

It also depends on the feel of the tempered film, which is very comfortable to hold, and the surface is smooth without pimples. It is best to choose a full cover of the tempered film, which will reduce the edge breakage of the tempered film.

In fact, for me, the biggest basis for distinguishing a tempered film is whether it is anti-fingerprint, in fact, as far as my own experience in buying tempered film is concerned, if you buy a tempered film that is not particularly anti-fingerprint, then it will give you a special headache. Because most people will use their mobile phones to play games, such as Honor of Kings. In this game, special attention is paid to the feel of the mobile phone and the clarity of the picture.

If you buy a tempered film for a mobile phone that is not fingerprint proof, it will make the whole screen very dirty after using it for a period of time. All kinds of stains can condense on the surface of the phone. It's very disgusting to look at.

After buying a tempered film for an anti-fingerprint mobile phone, this situation will be avoided. The surface of the phone is always clean and does not need to be wiped with a cloth.

Secondly, there is another credential, that is, whether the tempered film of the mobile phone has the effect of anti-radiation and anti-blue light, and generally the surface of the mobile phone tempered film with anti-blue light effect will have a faint purple light. This will definitely avoid the damage of radiation to our body.

Method 1: Heads-up method.

First of all, the eyes and the screen should be basically parallel, and observe whether the crack can be seen in the light, if the crack can be seen, it means that the tempered film of the mobile phone is broken, but if you can't see it, it means that the mobile phone screen is broken.

Method 2: Tilt method.

Pick up the mobile phone, tilt the angle of about 30°, and observe whether the cracks of the mobile phone film and the cracks of the screen coincide from the side. Because if both screens are broken, the cracks on the phone will not coincide.

Method 3: Touch method.

If there is a slight crack or spread on the screen, you can gently touch the crack with your fingers, and if you can feel the crack with your fingers, it means that the tempered film is broken. However, if the fingers do not feel the crack and can only be seen through the eyes, it means that the screen is broken.

Generally, the crushing of the tempered film will not affect the display of the screen, nor will it affect the touch of the screen.

If the screen is broken, it will be divided into a broken inner screen and a broken outer screen. If the inner screen is broken, a black screen will be displayed, and no content will be displayed; The outer screen is broken, but it can't be operated on the screen, the touch fails, and the screen content will be displayed.

The ordinary film is that the screen is broken, the film is still there, and the tempered film is that the film is broken, and the screen is still there.

Scratch resistance: A good tempered glass film can fully withstand hard and sharp items such as blades, scissors, and keys grinding on it.

Smoothness: A good tempered glass protective film feels very delicate and smooth to the touch, and it feels better than the original touch screen of many mobile phones. The glass film that almost leaked was rough and not smooth enough, and when it slid on the phone, there was a sticky feeling.

Size fit: The cutting requirements of a good tempered glass film are relatively high, and the size is perfectly covered, especially in some holes, which can be more reflected, and there are no bubbles when pasted.

Explosion-proof performance: good toughness, density and strength of the tempered glass protective film are very good, mainly manifested in the glass fragmentation is to maintain one.
