Patent

CA 2248283

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.

Dans cette diode lumineuse, multicolore et organique, on utilise des couches empilées verticalement (308, 310, 312) de dispositifs à double hétérostructure et fabriqués à partir de composés organiques. On forme cette structure verticale empilée (300) sur une base de verre (302) sur laquelle on dépose un revêtement transparent en oxyde d'étain dopé à l'indium (304) ou en métal similaire, afin d'obtenir un substrat sur lequel on dépose un agencement d'empilement vertical de trois dispositifs (308, 310, 312) à double hétérostructure, chacun étant fabriqué à partir d'un matériau organique approprié. On agence cet empilement de manière à ce que la double hétérostructure possédant la plus grande longueur d'onde soit située sur le sommet de la pile.
