| abstract |
An organic light-emitting diode (OLED) device which produces substantially white light including a substrate, an anode disposed over the substrate, and a hole injecting layer disposed over the anode. The device also includes a hole-transporting layer disposed over the hole injecting layer, a blue light-emitting layer doped with a blue light-emitting compound disposed directly on the hole-transporting layer, and an electron-transporting layer disposed over the blue light-emitting layer. The device further includes a cathode disposed over the electron-transporting layer and the hole-transporting layer or electron-transporting layer, or both the hole-transporting layer and electron-transporting layer, being selectively doped with super rubrene or derivatives thereof which emits light in the yellow region of the spectrum which corresponds to an entire layer or a partial portion of a layer in contact with the blue light-emitting layer. |
