Micro arcing occurs due to static electricity when equipment touches or is separated from glass.
Considering LCD and OLED manufacturing and transport situations, glass touches a wide variety of pads or equipment. During the process, electric charge is charged in the pad or equipment. After that, micro arcing occurs due to static electricity when the pad or equipment touches or is separated from glass. Then, a cell defect is found in the device (glass).
Using a graphene solution, KB ELEMENT developed a hybrid graphene solution which improved particle occurrence, unstable electrical conductivity and poor antistatic effects.
