RGB Color Ink

The top emission-type OLED requires a technology to form a color filter directly on the encapsulation layer (CoE ; Color filter on Encapsulation) and the color filter layer needs to be formed at temperature below 100℃ to prevent thermal damage to OLED. The photocurable RGB color ink replaces the existing photolithography-based high temperature curing process, and it forms the color filter based on ambient UV curing process after ink-jet printing. Since it doesn’t cause thermal damage to OLED, it allows CoE (Color filter on Encapsulation) structure and top emission OLED. RGB Color Ink
