Chinese engineers have invented a wonderful device that can restore broken OLED screens. This innovation attracted the attention of the world media. The device uses the excimer laser annealing (ELA) process, which allows you to transform damaged areas of the screen into polycrystalline silicon.

Then a special microscope removes scratches and chips, while the protective glass remains intact. OLED displays are an expensive and vulnerable component of smartphones. However, with new technology and the ability to repair damage without replacing the entire screen, the lifespan of devices can be significantly extended.

The ability to repair OLED screens with the help of this device could revolutionize the world of mobile technology. If this technology is widely used, smartphone owners will be able to avoid expensive screen replacements.
