Electron injection in OLED organic layers is improved by using alkaline‐earth or alkali metals as cathode layers or as dopants inside organic layers. An innovative metal dispensing technology has been developed to overcome handling problems and to ensure controlled and reliable metal layers deposition for OLEDs.
