摘要
A method of compacting moisture-sensitive organic material adaptable for making an organic layer on a structure which will form part of an organic light-emitting device, includes placing such a desiccant material in a powder form inside a die cavity (30) and applying a pressure to such a desiccant powder in the die cavity sufficient to compact into a porous desiccant bed (20); providing moisture-sensitive organic material in a powder form (24); and placing such moisture-sensitive organic material (24) inside the die cavity (30) over the porous desiccant bed (20), and applying sufficient heat to the moisture-sensitive organic material in the die cavity to cause moisture to escape from the moisture-sensitive organic material and be absorbed by the porous desiccant bed, and then applying sufficient pressure to compact the moisture-sensitive organic material into a solid organic pellet.
