DuPont claims OLED record fit for TV apps

The company said the results are sufficient for future OLED televisions.
DuPont has applied its advances in materials science to a scalable manufacturing process where an OLED television operating eight hours per day would last over 15 years, according to the company. (This feat assumes typical 30 percent duty cycle, running video).
"The current high-cost of manufacturing with evaporated materials has limited market adoption, and constrained OLED manufacturing for larger size displays,"said David B. Miller, president, DuPont Electronics & Communications, in a statement.
"Now, with DuPont printed OLED materials and process technology, fabrication costs can be significantly reduced, and manufacturing can be scaled to accommodate TV-size displays."
Printed devices using the DuPont process have reliably achieved lifetimes to 50 percent of initial luminance of 29,000 hours for red, 110,000 hours for green and 34,000 hours for blue at typical television brightness levels.
These results have been obtained under the following constraints:
