DuPont posted their financial results for 4Q 2011 (small decline in 4Q earnings and record annual earnings) - and the company recorded $20 million income from OLED technology licensing. Back in November 2011 DuPont announced that it has signed a licensing agreement with a leading Asian AMOLED maker - for the OLED nozzle printing technology, which will be used to make OLED TVs. The $20 million (or at least parts of it) may be fees for that license.

DuPont's nozzle-printing (or "spray-printing") technology uses a continuous stream of ink (unlike the droplets used in regular inkjet printing) to deposit OLED materials. This is a very fast process - DuPont says it can print a 50" TV in under 2 minutes, but the display isn't optimized in the sub-pixel level and is so less efficient than in other patterning technologies. But the faster throughput can lead to cheaper displays - in fact DuPont claims that this technology may make an OLED TV cheaper than an LCD TV.
