ABSTRACT:
A tandem white OLED device includes an anode, a cathode, and a plurality of organic electroluminescence units disposed between the anode and the cathode, wherein each organic electroluminescence unit includes at least one light-emitting layer, and wherein each organic electroluminescence unit emits white light. The device also includes an intermediate connector disposed between each adjacent organic electroluminescence unit, wherein the intermediate connector includes at least two different layers, and wherein the intermediate connector has no direct connection to an external power source.
