© 2014 IEEE. A new type of solid state thin film white light emitting device has been studied. Light is emitted due to thermal excitation of the nano size conductive paths formed after the dielectric breakdown of the amorphous metal oxide thin film deposited on a silicon wafer. The mechanism of light emission, optical characteristics, reliability, driving methods, and efficiency are discussed. The complete device is made of the IC compatible materials and process.
