In-situ vacuum method for making OLED devices

摘要

An in-situ vacuum method for fabricating, at least in part, an OLED device that is moisture- or oxygen-sensitive, such method including providing into a vacuum coater (10) a receiver element (42) which will form part of the OLED device; providing into said vacuum coater a donor support element (30) and coating such donor support element to produce a donor element (31) with one or more layers required to produce all or part of the OLED device; positioning the coated side of the donor element (31) in material transferring relationship to the receiver element (42) to be coated; and applying radiation (40) to the donor element (31) to selectively transfer in vacuum one or more layers from the donor element (31) to the receiver element (42).
