Scratches and damage on the display are annoying with a smartphone, tablet or notebook.

Above all, minor scratches could be repaired without further tools. The polymer has a kind of reminder function and can remember how the surface was obtained at the time of delivery. If there are any deviations from this, the original state can be restored.
Repair with heat
For this purpose, the polymer layer is heated so that these defects can be removed in the surface by heat. However, this does not happen automatically. According to the patent, the user marks the defective spots on the display and the polymer begins to repair them. The defective parts are marked by means of circling. This leads to a correspondingly strong heat development, of about 60 degrees Celsius speaks the patent. During the repair process, the display should not be touched.

It is unclear whether smartphones with such a self-repairing display will come to the market. Even if Lenovo has received the patent for it, it is open whether it is finally installed in products.
