Abstract:
An in-situ method for fabricating, at least in part, an OLED device that is moisture- or oxygen-sensitive, such method comprising the steps of:a) providing into a controlled-atmosphere coater a receiver element which will form part of the OLED device; b) providing into the controlled-atmosphere coater a donor support element and coating such donor support element to produce a donor element with one or more layers required to produce all or part of the OLED device; c) controlling the atmosphere in the controlled-atmosphere coater so that either the water vapor level is less than 1000 ppm but greater than 0 ppm or the oxygen level is less than 1000 ppm but greater than 0 ppm, or both the water vapor level and oxygen level are respectively less than 1000 ppm but greater than 0 ppm; d) positioning in the controlled-atmosphere coater the coated side of the donor element in material transferring relationship to the receiver element to be coated; and e) applying radiation in the controlled-atmosphere coater to the donor element to selectively transfer one or more layers from the donor element to the receiver element while providing a total pressure in the controlled-atmosphere coater greater than 1 Torr.
