We are accelerating the development of inks for the printed OLEDs. Small molecules including electron or hole transport type for EML and polymers with reduced the molecular weight for HIL/HTL have been developed as the best practice for high-resolution panels. Further, no-diffusible p-dopants and deep-red emitter have been developed.
