Abstract
A drying chamber for drying a substrate patterned with display areas wetted by OLED materials dissolved or suspended in a volatile carrier liquid and separated from one another by dry boundary regions. A mask adjusts drying rate of the carrier liquid during vacuum extraction using vapor-transmissive areas opposite the wet areas and vapor-barrier regions opposite the dry boundary regions, or by confining the wet areas collectively in a chamber volume small enough to quickly saturate with the carrier liquid before vacuum extraction.
