Good quality products, the screen has been processed, and has high stress resistance; bad products do not need to be filmed, and if it breaks, replace it. NS. Do you want to post it?
The scratch resistance of the touch screen
Regarding the touch screen, its material is a piece of glass, but different materials of glass will have different hardness and scratch resistance. German mineralogist Frederich Mohs divided the mineral hardness into ten grades, from 1 to 10 are graphite, touch screen computer，gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond. Among them, the lowest hardness is graphite, and the highest hardness is diamond. The main component of pure glass is silica, that is, quartz, with a hardness of 7, but the touch screen has to consider the requirements of volume, weight, touch, and light transmission, so its hardness is about 6-7.
In daily life, the finger that is most often in contact with the screen has a nail hardness of less than 3, which will not cause any impact on the screen at all. And many metals have a hardness of 5.5, so the glass in the bag that is most likely to rub against the screen has little effect on the screen.
Nowadays, the screen technology of touch screens should not be difficult to prevent scratches, so there is no need to do so.
