<p>A tandem OLED includes an anode and a cathode. The OLED also includes at least two electroluminescent units disposed between the anode and the cathode, wherein each of the electroluminescent units includes at least one hole-transporting layer and one organic light-emitting layer. An intermediate connector is disposed between adjacent electroluminescent units, wherein the intermediate connector includes an n-doped organic layer and an electron-accepting layer, the electron-accepting layer being disposed closer to the cathode than the n-doped organic layer, and wherein the electron-accepting layer includes one or more organic materials, each having a reduction potential greater than -0.5 V vs. a Saturated Calomel Electrode, and wherein the one or more organic materials constitute more than 50% by volume of the electron-accepting layer.</p> |
