Hello, everyone. Lin Fei has come to answer the above questions. How much does it cost to repair the broken mobile phone screen? many people don't know if the mobile phone screen is broken. Now let's take a look at it!

In recent years, the development of mobile phones is getting faster and faster, the same hardware is becoming more and more high-end, and the functions are more and more abundant. As a result, people can not meet the needs of small screens, 4-inch, 4.7-inch mobile phones gradually appear, and even today's 5-inch mobile phones with large screens can be found everywhere. A larger visual experience is really better, but it is more likely to be damaged. In the process of using mobile phones, accidents are inevitable if you don't pay attention to them. Today we are going to teach you how to repair the mobile phone screen.

How to fix a cracked mobile phone screen?

Method one

Step 1: remove the rear case of the phone.

Step 2: 3360 remove the screw. Note that if your phone has never been repaired, a piece of paper seals the screw hole. This should also be removed and should not be forgotten.

Step 3: 3360 remove the circuit board of the phone. Just be gentle and don't damage the motherboard.

Step 4: 3360, first connect the circuit with the bought outer screen and test whether the effect is good or not.

Step 5: 3360 remove a shell from the outer screen. Be careful to heat it with a hairdryer before dismantling it, otherwise the glue inside is too tight for you to take off.

Step 6: 3360 apply a layer of double-sided glue on the back of the removed shell. Pay attention to tear off the original layer of glue, or different thickness, not close enough.

Method 2

Repair with glass glue, which is a kind of ultraviolet glue (also known as shadowless glue, is an one-component UV-curable acrylic resin glue that can only be dry-bonded under ultraviolet radiation).

1. First, clean the mobile phone screen

two。 Smear the water on the broken phone screen with the matching scraper and pay attention to laying it evenly.

3. Irradiate with ultraviolet light for 10-15 minutes. It's done.

Can the broken screen be repaired with toothpaste?

1. The silicon in toothpaste can fill the scratch.

two。 The friction in toothpaste can smooth out small scratches. Toothpaste is rich in friction to smooth and repair tiny scratches on the phone's screen.

So, do these two statements make sense? Let's take a look at the ingredients in toothpaste:

Toothpaste is a complex mixture. It is usually made of friction agents (such as calcium carbonate, calcium hydrogen phosphate, calcium pyrophosphate, silicon dioxide, aluminum hydroxide), wetting agents, surfactants, thickeners, sweeteners, preservatives, active additives, pigments, flavors, etc. (Via Baidu encyclopedia)

According to netizens, what can play the role of "repair" is the friction (about 20% of toothpaste, about 50%). The so-called friction agent is the very fine particles contained in toothpaste. According to the national standard, the particle size of the friction agent is about 10 m / m ~ 20 m. The commonly used friction agents in toothpaste are calcium carbonate (CaCO3) and calcium hydrogen phosphate (CaHPO _ 4? H), silica (SiO2), aluminum hydroxide [A1 (OH) 3], etc.

According to the answer of the editor above, I believe we all know that toothpaste can not repair scratches on the phone screen, because it does not have the characteristics of repair at all. If you want to repair the phone screen, you have to use the above method, either honestly change the screen, or choose the glue that can be repaired is the right way. All right, that's all for today's question about how to fix the phone screen and whether toothpaste can fix the phone screen. I hope it will be helpful to you all.

At the end of this article, I hope it will be helpful to you.
