DuPont's New Ink Can Quickly Print Cheap OLED Displays
Want an ultra energy-efficient OLED television? You’ll have to pay — LG’s 15-inch display, for example, will cost a scathing $2,725 when it is released later this year. But OLED displays may not always be so pricey. DuPont has developed a new manufacturing process that can reportedly print a 50-inch TV screen that lasts 15 years in under two minutes. The development could eventually bring down OLED prices drastically.
DuPont teamed up with Japanese manufacturer Dainippon Screen to develop a garden hose-like printer that spews out a stream of ink, moving over a surface at rates of four to five meters per second all while patterning an OLED display. Today’s OLED printers use shadow-mask evaporation — a technique that patterns the organic molecules that make up the pixels in OLED displays. But shadow-mask evaporation only works at a small scale, unlike DuPont’s new printer.
We might not have to wait long to get our hands on DuPont’s cheap new displays. The company is already working to license its manufacturing process, which could bring OLEDs down to the cost of LED displays.
