OLED manufacturing for large area lighting applications

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
