    Printing LEDs on flexible plastic.

    Researchers in the University of Toronto's Department of Materials Science & Engineering have developed the world's most efficient organic light-emitting diodes (OLEDs) on plastic. This result enables a flexible form factor, not to mention a less costly, alternative to traditional OLED...

    Ultra-efficient Perovskite LED moving forward

    (Using less energy could mean less pollution for the planet. LEDs are a specialty area of mine that I deal with. I've even made an LED light that uses dead batteries! Back about 2005 white LEDs were very expensive, about $80 each. So a cheaper white LED was the holy grail back then. Now we can...
