    摘要： A method of depositing organic layers on a substrate in organic light emitting devices is disclosed. The method uses a donor support which is coated with a transferable coating of an organic donor material selected as one of a plurality of organic materials useful in an organic light emitting device. The donor coating is positioned in transferable relationship with the substrate in an environment of reduced pressure. The donor support is heated to cause the transferable coating of organic donor material to transfer to a position on or over the substrate and to form a layer of the organic material on the substrate.
