    Flexible/Printable Electronics:
    The printed electronics market comprises next-generation light, power and circuitry products, including flexible displays, plastic solar cells and organic RFID tags. Special inks enable the formation of active electrical layers -- the key drivers for printed electronics. The printed electronics market comprises next-generation light, power and circuitry products, including flexible displays, plastic solar cells and organic RFID tags. The market for printed electronics was approximately $1 billion in 2006 and is expected to exceed $300 billion within 20 years.

    OLED Display Technology:
    This talk will discuss a unique manufacturing process utilizing solution processing of small molecule materials for OLED displays and a material set including DuPont™ HIL hole injection layer and DuPont light emitting and charge transport materials – the essential materials used to make an OLED display.
    The OLED displays industry is under constant pressure to reduce manufacturing costs in order to compete with LCDs, This process should have the ability to overcome the cost barriers the industry has been facing.
    We have measured accelerated lifetimes of the three primary colors that could translate in a display to 20,000 hours of white lifetime (which is extended by as much as 5 times when showing video) at a normal viewing brightness (200 cd/m2). At 1,000 cd/m2— the standard test luminance used in the industry — the DuPont materials have lifetimes (T50) of 14,000 hours for blue with CIE 1931 color coordinates of (0.14, 0.16), 230,000 hours for green with color coordinates of (0.29, 0.65), and 46,000 hours for red with color coordinates of (0.66, 0.34). In a review of widely available reports, these are the longest measured lifetimes for a solution material set with equivalent color coordinates.
    The OLED materials are printed onto active-matrix thin-film transistor (TFT) backplanes supplied by leading TFT providers, and then protected from environmental degradation with encapsulation technology.

    Speaker Biographies:
    Charles E. Bauer, Ph.D. serves as Senior Managing Director of TechLead Corporation, a technology management company specializing in the electronics packaging, interconnection and assembly industry. Dr. Bauer focuses in the areas of strategic technology planning, market analysis and business development, primarily in the international arena. With more than 20 years' experience spanning the range from printed circuit board and hybrid fabrication through complex IC metallization, multilayer packaging, multichip modules (MCMs) and flat panel display packaging and assembly, he brings tremendous breadth and depth to his work. Dr. Bauer lectures throughout the world on technology, business and market topics as well as serving on several corporate boards and international corporate, government and educational institution advisory councils.
    Chuck served ISHM as President of the NW Chapter, Technical Chair of the ISHM National Symposium in Seattle, National Technical Vice President of the Society and President of the Rocky Mountain Chapter. He founded the ISHM/IMAPS Advanced Technology Workshop program and served as General or Technical chair for several ATWs between 1990 and 1998. Dr. Bauer also served on the Board of Directors of the SMTA from 1997 through 2001 when elected President of IMAPS for 2001-2002. He now serves as Chair of the SMTA International Development Committee and remains active internationally with the SMTA, IEEE, IMAPS, JIEP and ASM.

    Johann Trujillo is manager of the test engineering group of DuPont Displays, a subsidiary of DuPont based in Santa Barbara, Calif. He has held this role since 2001, developing test systems as well as providing failure analysis and performance testing capabilities. Prior to joining DuPont Displays, Dr. Trujillo worked at Motorola where he developed field emission displays.
    Dr. Trujillo received his bachelor's degree in chemical engineering at New Mexico State University and his masters and doctorate degrees in electrical engineering from University of California, Davis.
