Researchers from Japan has created a new OLED with a liquid organic semiconducting layer (made out of ethylhexyl carbazole - EHCz) to transport charge. This can useful for making flexible OLEDs, and also improve reliability.

The liquid semiconductor can be used in curved structures, or even could be circulated or refilled into the active emitting layer. This constant, fresh supply of semiconductors could improve device reliability and reduce degradation.
