 them," said Thomas M. Connelly, DuPont executive vice president and chief
 innovation officer. "The displays marketplace is a great example of DuPont
 science at work for a multi-billion dollar industry where our innovative
 technologies and products provide better and lower cost solutions for our
 customers and consumers around the world."
     DuPont display innovations include:
       Liquid Crystal Display (LCD) technologies:
       -- DuPont(TM) 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 red, green and blue (RGB) donor
          films, and is currently in beta trials in a LCD fab.
       -- New commercial applications of DuPont(TM) 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

          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(TM) Optilon(TM) advanced composite reflectors film (ACR) for
          improved display luminance in applications ranging from televisions
          to notebooks, monitors and industrial displays.
       Organic Light Emitting Diode (OLED) technologies:
       -- A unique manufacturing process utilizing solution processing of small
          molecule materials for OLED displays and a material set including
          DuPont(TM) HIL hole injection layer and DuPont light emitting and
          charge transport materials - the essential materials used to make an
          OLED display.
       -- DuPont(TM) Drylox(TM) cover glass is an encapsulation technology that
          effectively absorbs moisture and other contaminants while simplifying
          the manufacturing process.
       Plasma Display Panel (PDP) technologies:
       -- Lead-free DuPont(TM) Fodel(R) paste is now available with reduced
          ruthenium content.  The global industry standard for thick-film
          metallization, Fodel(R) is environmentally smart, cost-effective,
          easy-to-use and provides the fine-line resolution required for full
       -- 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
       Field Emission Display (FED) technologies:
       -- Introducing a photoimageable, thick-film paste now in development
          with high electron emission efficiency, high intrinsic material
          lifetime and easy processing.  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(R), Mylar(R) and Teijin(R) Tetoron(R) brands of polyethylene
          terephthalate (PET) films and Teonex(R) 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.
