    • A method for making an electrode over a light emissive layer in an organic light emitting device includes providing the organic light emitting device into a vacuum chamber having a receptacle for vaporizing material. Heating the receptacle to evaporate material placed in the receptacle for deposition onto the light emissive layer to form the electrode, and a shutter, which when open, permits evaporated material from the heated receptacle to deposit onto the light emissive layer. The method also includes selectively feeding an elongated member made of material to be evaporated into the heated receptacle when the electrode is to be formed and removing such material from such heated receptacle when such electrode is not to be formed.
    • 在有机发光器件中制造电极在发光层上的方法包括将有机发光器件提供到具有用于蒸发材料的容器的真空室中。 加热容器以蒸发放置在容器中的材料以沉积到发光层上以形成电极;以及快门,其在打开时允许来自加热的容器的蒸发的材料沉积到光发射层上。 该方法还包括当要形成电极时,将由待蒸发的材料制成的细长构件选择性地进料到加热的容器中,并且当不形成这种电极时,从这种加热的容器中去除这种材料。
