ABSTRACT:
An OLED device includes an anode, a cathode, and at least one individually selected organic light-emitting layer disposed between the anode and cathode. The device also includes an electron-transporting layer disposed between the at least one light-emitting layer and the cathode, such electron-transporting layer including a first electron-transporting material, and an electron-injecting layer disposed between the electron-transporting layer and the cathode, such electron-injecting layer including a metal dopant having a work function less than 4.0 eV and an electron-transporting material that is different from the first electron-transporting material.
