In May 2010 Dupont announced that they reached the goal to print a 50 inch OLED-Tv in under two minutes. In October 2011 Duponts announced that the company has signed a technology licensing agreement for that technology with a leading Asian manufacturer of Active Matrix Organic Light Emitting Diode display products. We think that it can be Samsung or LG-Display but at the moment it is not clear and not official. Duponts suggest that OLED is the next generation display technology which requires fewer components than LCDs and can utilize existing LCD infrastructure for as much as 30 percent overall cost savings.

Solution Process AMOLED Technology
How we can reach the goal to produce cheap OLED-Television device for the consumer market?
To reduce the manufacturing costs Dupont has developed a proprietary solution based printing technology that efficiently dispenses liquid OLED materials.

"AMOLED television market is projected to grow to over $5 billion by 2017."

DuPont has developed a proprietary solution-based printing technology that efficiently dispenses liquid OLED materials that it has developed to optimize display yields and performance.
The process is designed to significantly cut production costs for television-sized displays when compared to the current methods of producing AMOLED or LCD displays.

The critical exception is the nozzle printer, for which commercial systems have been produced up to full-size Gen 4 (0.7 × 0.9 m). The basic technology is fundamentally scalable, however, with engineering under way to deliver a fullsize Gen 8 system.
If this goal is reached OLED-Tv can be produced for the consumer market.Nozzle printing provides multiple continuous streams of OLED solutions that are drawn
across the substrate at high speed using production equipment that Dai Nippon Screen Co. (DNS) developed in partnership with DuPont. The simple control requirements
allow excellent uniformity to be achieved

What about the lifetime?
Printed lifetimes are quoted at subpixel luminances that simulate 200-nit FOS white brightness. Even for blue, the most challenging color, lifetime exceeds 30,000 hours and should be sufficient for many display applications, including OLED TV.
