    Abstract: Light-emitting bipolar devices consist of a light-emitter formed from an electroluminescent organic light-emitting material in contact with an insulating material. The light emitter is in contact with two electrodes that are maintained in spaced apart relation with each other. The light emitter can be formed as an integral mixture of light emitting materials and insulating materials or as separate layers of light-emitting and insulating materials. The devices operate with AC voltage of less than twenty-four volts and in some instances at less than five volts. Under AC driving, the devices produce modulated light output that can be frequency or amplitude modulated. Under DC driving, the devices operate in both forward and reverse bias.
