Abstract:
A method for fabricating an organic light emitting diode and a device thereof are provided. The method includes: providing a substrate; dispensing to the substrate a second organic molecule solution resulting from dissolving a second organic molecule in a solvent; applying the second organic molecule solution to a surface of the substrate so as to form a wet film layer; and heating the wet film layer by a heating unit to remove the solvent therefrom and thereby form a second organic molecule film. The method is effective in fabricating a uniform multilayer structure for use in fabrication of large-area photoelectric components.
