Researchers from the University of Florida has developed a new night-vision technology using OLEDs. They are using thin-film OLED panels to convert infrared light to the visible spectrum. The design has 7 separate OLED layers - each one amplifying the signal and converting it to the visible spectrum.
They say that a full-scale night vision can weight less than 125 grams and be very efficient. This can revolutionize night vision as we know it. They have currently made a prototype that's only 1 square cm in size, but in 18 months they hope to scale it up to a cell-phone display size, or even a car windshield. This research is funded by DARPA.
