Osram has developed a large-area transparent white OLED that achieves a luminousefficacy of over 20 lm/W at a brightness of 1000 cd/m2. The company hopes that further improvements to these performance values will open up new applicationsin the lighting market.
“The product is extremely thin, efficient, transparent and flexible with an excellent quality of light. It could be used as light partitions that are almost invisible by day and then provide a pleasant diffused light at night.
The transparent OLEDs are still in the R&D stage and increasing performance values significantly is one of Osram’s major goals.
The prototype is transparent either on or off and exhibits a transparence of 55%, which the company hopes to increase to 75%.
In addition to conventional lighting and emerging LED technology, Osram believes that the market offers room for new applications that are possible only with transparent OLEDs.
Osram expects the market launch to be predominantly in the luxury lighting design sector.
