Latest Patents

Yokoi's latest patents include a method for manufacturing an organic functional layer and an organic functional device manufacturing apparatus. The method involves forming a coated film of an organic functional material by applying a coating liquid to a substrate using a printing method. This coating liquid contains an organic functional material dissolved or dispersed in a first organic solvent. The process further includes bringing the coated film into contact with vapor or liquid of a second organic solvent, which is chemically non-active and can be mixed with the first solvent without dissolving the organic functional material. Additionally, he has developed an organic electroluminescence element that features a partition wall covered by an insulating layer. This method ensures minimal outgassing from the partition wall, thereby controlling damage to the organic light-emitting medium layer and ensuring a uniform film formation.
