Why use a dust-free cloth to clean the display and touch screen
The display screen and touch screen are produced in a dust-free workshop. The factory uses ultra-fine fiber dust-free cloth, which is not easy to scratch the plastic sheet and glass substrate. Some people say that you can't use fiber wipes, but use cotton. In fact, cotton itself is a plant fiber, and the ultrafine fiber used in industry is much thinner than cotton fiber. The wipes should be disposable. In other words, it cannot be used after it has been used.
If you clean the screen and then clean it yourself, take what to ensure that the rag is clean. Because the tap water contains impurities, cleaning the screen with a dust-free cloth cleaned in this way will cause great damage to the polarizer. It's just very small and invisible for a while. It is obvious that the water cleaned by professional dust-free cloth is purified water of 18M Euro after purification treatment. Some people say that using a normal soft cloth to clean the screen is not a big problem. This is a step-by-step process. You can't see the difference once or twice. When the number of times is too high, the screen is fuzzy and cannot be solved. At this time, the only way is to change the polarized light. Sliced. This process is relatively complicated and requires special equipment in the factory. For example, to peel off the polarizer, special peeling equipment is required. Manual peeling can easily damage the panel.
Some people say that glasses cloth or suede can be used. The spectacle lens is made of glass or hard resin, which has high abrasion resistance, and deerskin is relatively soft, but can it be guaranteed that it will not lose impurities? It is not advisable to wipe the screen with glasses cloth.
