Encapsulation System

KORONA™ ENC

It is a process to seal with Glass to prevent penetration of oxygen and moisture, after all the processes of AMOLED has been progressed. It performs sealant process of large area AMOLED, at least the size of generation 4, and we provide facilities for the entire sealant process, unique in Korea.

Technology

After spraying the sealant to draw the shape of outward appearance, and then going through the assembly process of upper board and lower glass board, UV is irradiated to harden the sealant.
