David Okrent lifetime. In 1997, Hung et al. showed that a very thin 1–2 nm lithium fluoride (LiF) layer adjacent to the ETL and aluminum cathode which greatly improved the injection efficiency for OLEDs, resulting in a low operating voltage at high brightness (Hung et al. 1997). The improved injection efficienc
