During the epidemic period, a variety of disinfectants and cleaners containing alcohol have become common things at home, and mobile phones we hold in our hands every day, it is easy to contaminate various pathogens, since various cleaners containing alcohol can both clean oil and kill germs, is it not the most appropriate to use them to wipe the LCD screen?
That's true, but if you don't wipe it right, it's likely to damage your phone or other electronic devices.
Because, using alcohol to wipe the LCD screen, it is likely to cause irreversible serious damage to the screen. So, why does alcohol have a strong erosive effect on LCD screens? The LCD screen is composed of multi-layer materials, and its LCD screen is composed of multi-layer materials, and its core is a sandwich structure with a layer of liquid crystal molecules sandwiched between two polarizers. Whether it is a polarizer or the liquid crystal molecule itself, it is a substance that is very soluble in alcohol, and once it is eroded by alcohol, it will dissolve immediately and the screen will become mottled.
However, modern LCD screens, especially various touch screens, are actually not so fragile. Because we will also set a glass cover on the top layer of the screen, this layer of cover mainly plays a role in preventing scratching and damaging the screen, and it can naturally block all kinds of moisture and solvents from the outside world from directly contacting the structure below.
But even so, wiping a screen with an alcohol-based cleaner is a pitfall for two main reasons.
First, the surface of the glass cover is actually coated with a special organic film, such as an oleophobic film, which can reduce the adsorption of grease and alleviate the effect of fingerprints staining the screen. Most of these coatings are various organic compounds, the resistance to alcohol is very weak, if coupled with external forces to wipe, the coating is more likely to fall off, resulting in the screen flowering. Of course, if the mobile phone screen is pasted with a film, then you don't have to worry too much about this problem.
Second, although the top layer of the LCD screen, that is, its surface is not so squeamish, its side is still very fragile. Most of the LCD screens damaged by alcohol are actually because alcohol seeps into the gaps on the side of the screen, which is equivalent to avoiding the glass panel and directly drilling into the lower structure. The surface tension of alcohol is weak, the capillary effect is strong, and once there is a gap that can be drilled, it will quickly invade it, and the consequences are naturally very annoying. If a small amount of alcohol enters the inside of the screen, the device can be turned off immediately to dry or blow dry with a hair dryer, which will not affect subsequent use.
Therefore, when the screen of our computer, tablet or smartphone needs to be cleaned, we can spray some special LCD cleaner, and then wipe it with a soft cloth to make the screen look new. LCD cleaners have a very good removal effect on fingerprints and oil films, and many wet wipes have similar functions.
These cleaning products contain a mainly surfactant, which has a good cleaning effect on oil stains and does not damage various organic coatings. If there is no similar cleaner, the LCD screen can also be cleaned with a damp cloth dipped in a very small amount of pure water, but it is important to be careful not to let the water flow into the gaps around the screen.
To sum up, if it is just for cleaning, then it is safest not to use alcohol, if there is a need for disinfection, then you should be cautious, some mobile phone products will be nominally available alcohol disinfection, it is recommended to read the instructions and then disinfect. In addition, when disinfecting the mobile phone with alcohol, it is also recommended to first dip the alcohol on the soft cloth, and then gently wipe it with the soft cloth, do not spray or pour alcohol directly on the screen, so as not to flow alcohol everywhere and increase the risk of eroding the original screen and damaging the mobile phone.
