DISPOSITIF ELECTROLUMINESCENT ET SON PROCEDE DE FABRICATION, ET PROCEDE POUR FORMER UN CONTACT CONDUCTEUR TRANSPARENT

摘要

A multicolor organic light emitting device employs vertically stacked layers (308, 310, 312) of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure (300) is formed on a glass base (302) having a transparent coating of ITO (304) or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices (308, 310, 312), each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack.
