<p>A white light-emitting OLED device including a spaced anode (320) and cathode (380), a hole-transporting layer (340) disposed over the anode, and a first light-emitting layer (350) disposed on the hole-transporting layer including an electron-transporting material host and a yellow dopant for producing yellow light. The device also includes a second light-emitting layer (360) disposed on the first light-emitting layer and including a blue host and a blue dopant for producing blue light, and an electron-transporting layer (370) disposed between the cathode and the second light-emitting layer.</p> |
