[OLED1-2 (Invited)] Latest Progress of Solution-Process OLED Materials with Small Molecule Based Emission Layers
Printed OLED, Ink jet, Small molecule, No-diffusible p-dopant, Narrow FWHM emission
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.
