15-inch OLED TV is the cheapest you can get -- but at about $2,500 it won't be rocking too many peoples' lives. We've heard promises of dropping costs thanks to printed displays for ages now, but never on a scale like this. DuPont has teamed up with Dainippon Screen to create a printing technique capable of line-feeding a 50-inch display in just two minutes. Two minutes! The printer is likened to a high precision garden hose, flying over the display surface at a speed of five meters per second depositing that good, good OLED juice in just the right places with nary a drip or an unwanted sprinkle. DuPont Displays President William Feehery says the technique "is worth scaling up" and could compete on cost with LCDs while delivering a 15-year lifespan. That's not quite the 100 years they promised us last time, but we'll take it. No word on when, or if, this technique will actually be deployed en masse.
