METHOD OF MANUFACTURING WHITE LIGHT ORGANIC ELECTROLUMINESCENCE ELEMENT

摘要

PURPOSE: A method for manufacturing a white light organic electroluminescence device is provided to synthesize and process a guest material by mixing Dimer and DCM at a ratio of five to five and using the mixture as the guest material. CONSTITUTION: A transparent electrode(22) is coated on a glass substrate. The transparent electrode(22) is etched according to a designed display structure. Dimer and DCM are mixed with each other to manufacture a luminous material as a guest material. The guest material is mixed with a polyimid, namely, a host material. A hole transport material is coated on an upper part of the transparent electrode(22) which is formed of the wanted structure. The mixture of the host and guest materials are coated on an upper part of the coated hole transport material to form a luminous layer(23). An electron transport material is coated on an upper part of the luminous layer(23). A metal on which a cathode is applied is coated on an upper part of the coated electron transport material. The device coated with the metal is packaged.
