摘要:
A tandem white OLED includes an anode; a cathode; at least one broadband electroluminescent unit disposed between the anode and the cathode, wherein the broadband electroluminescent unit includes at least one light-emitting layer and produces at least one color component having an intensity less than desired; at least one color-compensating electroluminescent unit disposed between the anode and the cathode, wherein the color-compensating electroluminescent unit is selected to produce the at least one color component and to increase the color component intensity; and an intermediate connector disposed between each adjacent electroluminescent unit, wherein the intermediate connector has no direct connection to an external power source.
