A few days ago, DuPont has unveiled new printable OLED materials. DuPont now say that they can print a 50" OLED TV in under two minutes. They are using a custom-made printer from Dai Nippon Screen Manufacturing Co.
Dupont worked with Dai Nippon Screen to develop a multi-nozzle printer for the new inks. The Dai Nippon printer generates a continuous stream of ink, rather than droplets, and moves over a surface at rates of four to five meters per second while patterning a display.
