Organic electroluminescent devices are light-emitting diodes in which the active materials consist entirely of organic materials. Here, the fabrication of a white light-emitting organic electroluminescent device made from vacuum-deposited organic thin films is reported. In this device, three emitter layers with different carrier transport properties, each emitting blue, green, or red light, are used to generate white light. Bright white light, over 2000 candelas per square meter, nearly as bright as a fluorescent lamp, was successfully obtained at low drive voltages such as 15 to 16 volts. The applications of such a device include paper-thin light sources, which are particularly useful for places that require lightweight illumination devices, such as in aircraft and space shuttles. Other uses are a backlight for liquid crystal display as well as full color displays, achieved by combining the emitters with micropatterned color filters.
有机电致发光器件是一种发光二极管，其活性材料完全由有机材料组成。在此，报道了一种由真空沉积有机薄膜制成的白色发光有机电致发光器件的制造方法。在该器件中，使用具有不同载流子传输特性的三个发射层，每个发射层分别发射蓝色、绿色或红色光，以产生白光。在15至16伏等低驱动电压下成功获得了超过每平方米2000坎德拉的明亮白光，几乎与荧光灯一样亮。这种器件的应用包括超薄光源，这对于需要轻质照明设备的场所特别有用，例如在飞机和航天飞机中。其他用途是作为液晶显示器的背光源以及全彩色显示器，通过将发射体与微图案化滤色器相结合来实现。
