Analysis of iPhone screen's water resistance | Ainongji - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

To judge whether the iPhone screen is the original screen, there was a saying on the Internet that the original screen would do special treatment on the surface and cover the surface of the glass with a coating, so the water drops on the original screen would stand up like the water drops on the lotus leaf, while the water drops on the non original screen might spread. Of course, the role of this coating is not to verify the authenticity of the screen, it has other purposes.

At ordinary times, we should also notice that when the rain falls on the lotus leaf, it will condense into a large water drop without scattering, and the water drops will not leave any water traces when rolling off the lotus leaf. There will be tension at the boundary where liquid and gas contact. The greater the surface tension is, the greater the surface energy is. It can also be considered that the more active the surface is, the easier it is to adhere to other objects. The lotus leaf has such a special ability because its special structure can reduce the tension between the lotus leaf and water, making it super hydrophobic.

The mobile phone screen often has close contact with our hands. During the contact process, fingerprints are often left on the screen, affecting the screen's beauty and experience. The surface tension of ordinary glass is more than 500, which is easy to adhere to other substances. To be water resistant like lotus leaves, a film needs to be coated to reduce the surface tension of the glass surface, so that dust Adhesives such as water are difficult to stand on the screen surface. Its greater role is to resist fingerprint. In addition, it can also make the screen smoother.

In fact, this kind of coating is not only on the iPhone screen, but also on some slightly better mobile phone screens. In order to save costs, shanzhai mobile phones may omit this step.
