ABSTRACT:
An electroluminescent device utilizes a plurality of embodiments to minimize the variation in luminance due to changes in the voltage across the device. These include a highly conductive hole injection layer in a bi-layer device, a thick hoe transporting interlayer in a tri-layer device and the addition of an external resistor in series with the device.
