Recent progress of materials and inks for the ink-jet printed OLED is reported. Newly developed HIL ink with reduced viscosity gives flat shape in pixels and is the best practice for high-resolution panel. Device performance is improved by new emitters with deep and sharp emission and durable skeleton.
