WILMINGTON, Del., May 12, 2010 - DuPont announced that it has achieved record performance in printed organic light emitting diode (OLED) displays, sufficient to enable future adoption of OLED television (TV). Using proprietary DuPont Gen 3 solution OLED materials, DuPont has for the first time demonstrated a solution-based manufacturing process in which OLEDs can be cost effectively printed while delivering the necessary performance and lifetime.
OLEDs are an inherently more sustainable display technology when compared with liquid crystal displays (LCDs). OLEDs have the potential for lower power consumption and eliminate the need for many of the LCD components, such as backlights and color filters. OLEDs also can offer consumers an improved viewing experience through higher contrast ratios and faster response times.
"OLED displays are in portable devices available in the market today, but 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. "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."
DuPont previously announced the development of solution-based OLED materials with record-setting lifetime performance. With the new results, DuPont has now translated its advances in materials science to a scalable manufacturing process where an OLED television operating eight hours per day would last over 15 years.1
To report these results, DuPont made printed test devices which can be operated at elevated luminance for an accelerated lifetime test. 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.2
DuPont is a world leader in the development of a broad range of innovative and more sustainable solutions that improve flat panel display performance, reduce costs and enable next generation breakthroughs across a broad range of display technologies, including printed OLED technology.
