4hw.com.cn: there has been a lot of debate about the issue of whether the mobile phone film is not applied. Some people think that the screen of the mobile phone is hard to scratch now. Some friends think that the screen film of the mobile phone is more secure. In fact, although the screen of the mobile phone is hard, there are still many hard things in life that will scratch the screen, which seems to kill obsessive-compulsive disorder. What about the scratches on the screen of the mobile phone? Here are some tips for Xiaobian to help you.
At present, there are two most effective ways to repair screen scratches:
1: Mobile screen repair solution (without damage to oil drainage layer)
This is a kind of liquid in glue state. The principle is to penetrate into the scratch of the screen and fill the 'groove' of the scratch, so that the scratch disappears. This kind of repair fluid has an extraordinary effect on the scratches with a wide range and a deep depth.
The key is that this kind of repair fluid will not damage the sparse oil layer on the screen. If you are bold and careful, it can be repaired perfectly. Then we use the drop test method to see that the sparse oil layer is still in place, which basically has no impact on the hand feel.
2: Grinding rare earth polishing powder
This is a kind of white powder solid, originally used for glass polishing, but the outer screen of mobile phone is also a kind of glass. So it's also been improved over the years, and it works wonders on mobile screens. In the early days, there were "toothpaste tutorials" on the Internet, in fact, the principle was similar, but if there were too many toothpaste abrasives, the mobile screen would be completely "disfigured".
This kind of polishing powder needs to be rubbed by hand. It takes at least 20 minutes to have an effect. It has a very obvious effect on small scratches. But for deep scratches, it is not recommended to use this method, because its principle is to thin the outer wall of the screen, so it will cause slight unevenness of the screen.
In the end, you'll find that your phone screen is the same as when you bought it, even when it's facing the sun. Of course, after finishing the screen scratch repair, it is recommended to stick a piece of toughened glass film, otherwise it will produce new scratches when used.
