DuPont Produces OLED Panels In Less Than 2 Minutes

OLED TV Display

It seems that for DuPont creating small OLED display for mobile phones isn’t the right challenge so they decided to start developing larger OLED panels for HDTV’s.

The interesting part of it is that they managed somehow to create a 50-inch OLED panel in less than 2 minutes. How is that possible? Well, the guys over at DuPont have used in the production process a special Dainippon printer and their own third-generation OLED inks. Creating large-scale OLED panels is also very expensive but, using this technology, DuPont not only reduce the production costs, but they also increase the lifetime to 15 years if the OLED panels are used for about 8 hours a day. This kind of panels are also low in power consumption and their production process doesn’t require so many components.

For the moment, there is no information on when the DuPont OLED panels will go on sale or about pricing, but you can find more useful information in the press release below.

Press Release

Cost-Effective Solution Printing Process and Materials Deliver Record Lifetime Performance
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.
