  • Method of manufacturing a bendable substrate coated with a coating layer of adjacent heterogeneous coatings bonded along boundaries thereof useful for foldable displays
    Patent number: 11130703
    Abstract: Disclosed herein are a method of manufacturing a heterogeneous coating solution bonded coating layer, and a coating layer and a cover window produced thereby. More particularly, there are provided a method of manufacturing a heterogeneous coating solution bonded coating layer, in which a step difference at the boundary between different types of coating solutions is controllable by controlling a difference in capillary number during discharge of the different types of coating solutions using a slot die coater, and a coating layer and a cover window produced thereby. Therefore, the method of manufacturing a heterogeneous coating solution bonded coating layer can produce a cover window that is excellent in all the properties including durability, optical characteristics, and flexibility.
