Abstract

An organic light emitting device (“OLED”), including a substrate, a conductive nitride electrode, an organic film, and a second conductive electrode. The conductive nitride films can be transparent or opaque depending on their thickness. The OLEDs provide high brightness and efficiency and can be incorporated into electronic devices, including computers, monitors, televisions, large area wall screens, theater screens, stadium screens, billboards, signs, vehicles, printers, telecommunications devices, and telephones.
