DuPont develops OLED technology scalable to TV-sized displays
Wilmington, DE--DuPont 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) and have the potential for lower power consumption and eliminate the need for many of the LCD components, such as backlights and color filters. These OLED displays 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. Printed devices using the DuPont process have reliably achieved lifetimes to 50% of initial luminance of 29,000 hours for red, 110,000 hours for green, and 34,000 hours for blue at typical TV brightness levels.
DuPont Gen 3 solution OLED technology is being showcased in private meetings at the SID Display Week show May 23-28, 2010, in Seattle, WA; contact Emi Harnden ([email protected]) for a meeting.
