Advances in Breakthrough Technologies for LCDs, OLEDs, PDPs and FEDs to be Displayed

DuPont Displays today announced that it will showcase recent innovations it has made in its material, process and film technologies for flat panel displays at the Society for Information Display’s (SID) International Symposium in Long Beach, Calif., May 20-25, 2007. Spanning LCD, OLED, PDP and FED technologies, DuPont offers many ground-breaking solutions with significantly improved performance, some commercially available for the first time.

"With our history of science and innovation, DuPont has been able to introduce at SID each year a wide range of breakthrough solutions to solve pressing industry challenges," said James Prendergast, vice president and chief technology officer, DuPont Electronic & Communication Technologies. "This year, we’re excited to announce that many of these technologies are now commercially available and others have been significantly improved to respond to evolving industry trends."

LCD technologies and innovations highlighted:

• DuPont™ Thermal Color Filters (TCF) system, a maskless, direct writing color filter manufacturing system, is highly scalable and significantly reduces production costs, process steps and cleanroom space. In the final stages of commercialization, the TCF system includes equipment, process, and RGB donor films, and is currently in beta trials in a LCD fab.
• New commercial applications of DuPont™ Direct Bonding technology, which increases a display’s sunlight readability by as much as 400 percent and impact and scratch resistance up to 300 percent. With two new production lines in Shenzhen, China, DuPont offers this cost-effective advanced technology, traditionally used in specialized avionics and military applications, for demanding tablet personal computer and marine electronics applications.
• Newly available DuPont™ Optilon™ anti-reflective film coating solutions for the manufacture of single-layer, wet-coated anti-reflective films that decrease LCD surface reflections, provide excellent abrasion resistance and reduce overall display costs by simplifying the traditional multilayer manufacturing process.
• DuPont™ Optilon™ advanced composite reflectors film (ACR) for improved display luminance in applications ranging from televisions to notebooks, monitors and industrial displays.

OLED technologies:

• Active-matrix OLED display technology, which combines solution-based small molecule OLED materials, innovative solution processing and encapsulation technology with active matrix backplanes from leading TFT providers.
• DuPont^™ HIL, a hole injection layer material that increases the lifetime and efficiency of OLED displays, is now commercially available.
• DuPont™ Drylox™ cover glass is an encapsulation technology that effectively absorbs moisture and other contaminants while simplifying the manufacturing process.

PDP technologies:

• Lead-free DuPont™ Fodel® paste is now available with reduced ruthenium content. The global industry standard for thick-film metallization, Fodel^® is environmentally smart, cost-effective, easy-to-use and provides the fine-line resolution required for HDTV.
• A dry film-based metallization technology providing finer line resolutions than previously possible. Now in the final stages of commercialization, Transfer Materials Technology (TMT) is highly scalable and easily automated for higher yield and lower cost of ownership.

FED technologies:

• Introducing a photoimageable, thick-film paste, with high electron emission efficiency, high intrinsic material lifetime and easy processing, that is in development. This emitter paste with associated activation process technology provides low power consumption and high-speed switching for applications ranging from TV to LCD backlighting, x-ray sources and vehicle displays.

Optical Films from DuPont Teijin Films:

• Melinex^®, Mylar^® and Teijin^® Tetoron^® brands of polyethylene terephthalate (PET) films and Teonex^® polyethylene naphthalate (PEN) films are the substrates of choice for applications such as reflectors, diffusers, electromagnetic interference (EMI) and optical filters, anti-reflective films and hard-coated films.
• High-performance films for flexible displays, designed to meet the unique requirements of the flexible display and printable electronics markets, with key characteristics such as flatness, low shrinkage and predictable dimensional changes with variable heat and moisture.
• Newly launched planarized PET films, which offer glass-like surface smoothness and cleanliness, are now commercially available.

DuPont and DuPont Teijin Films representatives will be available throughout the show in booth #1029, Exhibit Hall B to discuss these and other DuPont innovations for flat panel displays. DuPont and DuPont Teijin Films engineers will also present papers treating topics of interest within the OLED, display substrates, coatings and optical film sessions throughout the week at the symposium.
