SCREEN Finetech Solutions developed a new coater (SK-F1500H) for color filter film forming with anti-reflective properties. These color filters are intended to be used in flexible (foldable/rollable) OLED devices. The company says the new coater is able to achieve outstanding efficiency by executing the entire process in a single integrated line (6-Gen / 2 substrate).
SCREEN FT explains that in current rollable and foldable OLEDs, the multi-film structure is a weak point that is one of the reasons these display get wrinkled and damaged when bent. One of the problems is in the multi-layered circular polarizers. Color filter films can replace the polarizers, reduce the number of layers, and enable high transmittance and higher energy efficiency.
