Color-rich, energy-efficient, and flexible organic light-emitting diode (OLED) displays could soon be churned out more economically on giant inkjet printers. Mobile phone displays accounted for 71% of the US$4.9 billion 2012 OLED market. Within five years, it’s expected that more than half of all new phone displays will be OLED-based.
Other researchers area also making OLED based lights and solar cells. This thin film electronics has the potential to be low cost solar power, lights and displays.

OLED displays are widely expected to eventually supplant LCDs, the most common display today in TVs and computers. OLED displays use less power, have more vibrant colors, and can be made on plastic, making them attractive for flexible and even wearable electronics. The futuristic displays are already appearing in some expensive smartphones, digital cameras, and televisions. But manufacturing challenges have hindered attempts at mass production.
Kateeva has a movable platform that precisely positions glass panels or plastic sheets large enough for six 55-inch displays beneath custom print heads. Each print head contains hundreds of nozzles tuned to deposit picoliter-scale droplets in exact locations to build up the pixels of a display. The company says the tool can be incorporated fairly easily into existing display production lines.
