Patent ID: 7935963

Claim:
A hybrid organic light emitting diode for use in general illumination and flat panel display, and said organic light emitting diode comprising: a stack of organic thin film layers and inorganic thin film layers of anodes and cathode, contained between two optically transparent flat substrates; wherein the said stack of layers further comprising, among several layers, three light emitting layers making up two families of organic light emitting diodes; said two families of organic light emitting diodes of which one belonging to the phosphorescent family, based on dopants of heavy metal-atom-complex, of organic light emitting diode and the other belonging to the fluorescent family, based on small molecule, of organic light emitting diodes; said fluorescent family of organic light emitting diode comprising at least one blue light emitting layer; said phosphorescent family of organic light emitting diode comprising two light emitting layers of which one layer is for emitting red light and the other layer is for emitting green light; said two families of organic light emitting diodes electrically isolated from each other; wherein the said fluorescent family of organic light emitting diode and the said phosphorescent family of organic light emitting diode, when applied with suitable voltage, conducting currents independent of each other; upon conducting currents the said fluorescent family of organic light emitting diode emitting blue color light and the said phosphorescent family of organic light emitting diode emitting red and green color light; wherein the said red, the said blue and the said green color lights, after mixing inside the said hybrid organic light emitting diode device, exit the said device as white light.
