eMagin corporation logoeMagin Corporation has received notification of allowance from the U.S. Patent and Trademark Office for an anode design that features improved stability. The design effectively extends the lifetime of eMagin's OLED microdisplays.

eMagin scientists developed a single-layer, semi-transparent capable anode with efficient hole injection properties. The approach can improve the overall stability of the anode and OLED life by simplifying both the manufacturing process and the device structure.

"As more commercial and military users are attracted to the excellent performance and durability of our OLED microdisplays, we are continuing to incrementally improve upon the technology to make it more broadly useful," said Susan Jones, eMagin's chief marketing and strategy officer. "This new patent represents an important method to make high efficiency, long life OLEDs that should be compatible with a wide range of OLED materials. Aspects of this invention are already proving its worth in our products."
