Abstract:
1. Apparatus for use in making an OLED device by forming repetitive sequences of organic coatings on a flexible substrate, comprising: a) means defining a path for the flexible substrate; b) the flexible substrate being disposed about at least a portion of the path; c) first and second low pressure sublimation deposition sources for depositing different organic materials located in spaced apart positions around the path periphery and in cooperative relationship with the surface of the disposed flexible substrate; d) actuable means effective when actuated for moving the flexible substrate around at least more than one revolution around the path; and e) means for actuating the actuable means and the first and second low pressure sublimation deposition sources so that at least two separate organic material coatings are provided on the substrate by the low pressure sublimation deposition sources.
