What is OCA
OCA (Optically Clear Adhesive) is a type of optically transparent adhesive film used for bonding each layer of the touch screen panel (TSP) or cover glass to the display. It serves as a film-form adhesive for laminating panel materials and is an essential material in the manufacturing of displays for laptops, tablets, smartphones, and automotive applications.
OCA is primarily used in fields such as mobile phones, PCs/laptops, automotive, and industrial control, as well as in GFF touch screen bonding and LCD/OLED screen laminating.
