OLED manufacturing for large area lighting applications

Abstract We present first results of a new developed large area manufacturing system for organic light-emitting diodes (OLED) dedicated to lighting and signage applications. The system combines high throughput with flexibility in production at highly-precise deposition conditions. After introducing the system with its modules, first results for organic and metal layer deposition properties are shown. Next orange/red p–i–n type OLED samples are prepared on large ITO substrates and the characterization by luminance and current measurements are presented. The devices achieve very high efficiencies up to 31 cd/A on large area substrates which are comparable to devices on smaller substrates.
