Caledon Controls announced that they will co-develop their PDIM (Pre-Deposited Images in Metal on plastic film) technology to be used as transparent conductor for OLED lighting together with the University of Toronto. This is the same team that discovered that using chlorine can drastically reduce OLED device complexity and improve its efficiency.
PDIM film is patterned with a thin (<25um) trace grid made of pure metal achieving 90+ transparency with low resistance. We posted about this film and it's possible usages for OLEDs back in January 2011.
