摘要
An organic light-emitting diode (OLED) device which produces substantially white light includes a substrate; an anode disposed over the substrate; and a hole injecting layer disposed over the anode. The device further includes a hole-transport layer disposed over the hole injecting layer; a yellow light-emitting layer having rubrene or a derivative thereof greater than 50% by volume of the constituents of such yellow light-emitting layer that emits light in the yellow region of the spectrum and is disposed on the hole-transport layer; a light-emitting layer doped with a blue light-emitting compound, disposed directly on the yellow light-emitting layer; an electron-transport layer disposed over the blue light-emitting layer; and a cathode disposed over the electron-transport layer.
