Title (EN) PRINTING METHOD FOR AN ORGANIC LIGHT EMITTING DIODE (OLED)
(FR) PROCÉDÉ D'IMPRESSION POUR UNE DIODE ÉLECTROLUMINESCENTE ORGANIQUE (OLED)
Abstract:
(EN) The present invention relates to a method of manufacturing one or more layers of an OLED, the one or more layers containing an organic semiconducting material, comprising the steps of printing a solution with a piezo-electric printing device, the solution containing at least one organic solvent and at least one organic semiconducting material onto a substrate and of drying the printed solution, wherein the solution has a viscosity lower than 5 c P.
(FR) La présente invention concerne un procédé de fabrication d'une ou de plusieurs couches d'une OLED, la ou les couches contenant un matériau semi-conducteur organique, comprenant les étapes consistant à imprimer une solution avec un dispositif d'impression piézoélectrique, la solution contenant au moins un solvant organique et au moins un matériau semi-conducteur organique sur un substrat et à sécher la solution imprimée, la solution ayant une viscosité inférieure à 5 c P
