The screen of the Xiaomi Smart Watch/Xiaomi Smart Band has evenly divided stripes at specific angles

The watch adopts an AMOLED screen, which has a very thin film material in the polarizing film layer. The thinner the material, the more likely it is to shrink in the direction perpendicular to the stretching direction when stretched. It will leave ribbed marks after bonding with the substrate. This is normal, please feel free to use it.
