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 demonstrated for the first time a solution-based manufacturing process in which OLEDs can be printed cost effectively 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 in portable devices are 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 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 more than 15 years.
