The primary objective of the present invention is to provide a method for manufacturing organic layers of organic light-emitting device by using deposition machine, which mainly uses the way of premixing organic materials to dissolving and mixing multi kinds of organic materials; moreover, after completing the vacuum drying process to the mixed organic materials, the method is then proceeded for depositing the mixed organic materials on a substrate in single vapor deposition process; after then, the method is proceeded for ended the deposition process to the material carrier and repeatedly operating deposition process to another material container, so as to produce multi-layers structure on the substrate; wherein method proposed by the present invention can replace the conventional manufacturing process and can avoid the disadvantages thereof.

Method for manufacturing an organic element

The present invention provides a carrier transport material formed by completing a reaction process of at least one aromatic compound and at least one polycyclic aromatic hydrocarbons (PAHs), wherein a cross linking reaction can be activated in the molecular compound through heating or ultraviolet irradiation because the molecular compound has at least one cross-linkable functional group. Therefore, when the carrier transport material is applied in an OLED, the carrier transport material would not be dissolved by the solvent included in the next coated material because the carrier transport material has been cured after the cross linking reaction is carried out. Moreover, because the carrier transport material would simultaneously perform an electron confining functionality when being used as a hole transport layer, the device efficiency of the OLED having the carrier transport material is obviously enhanced during the high-brightness operation especially.
