SAN JOSE, Calif., Feb. 15 -- The Society for Information Display (SID) announced that its 2005 technical symposium will be extended from a three-day to a four-day event, May 24-27, as part of the SID 2005 International Symposium, Seminar and Exhibition, to be held May 22-27 at Hynes Convention Center in Boston. Organizers said they lengthened the symposium as a result of a 35 percent attendance increase at the 2004 symposium, and that accepted papers for the 2005 symposium are up almost 20 percent from last year, to 434. They said they also wanted to give attendees more time to visit the exhibit hall, which will be open May 24-26. Many of the most significant papers will be presented on Friday, May 27, after the exhibit hall closes. Dick McCartney, SID 2005 conference chair, said, "The Friday morning sessions are not an optional adjunct but rather an integrated part of the technical symposium. We want to be sure the entire 3 1/2 days are well-utilized and that the last half-day is of substantial value to attendees." Papers will focus on developments and breakthroughs in large-screen flat-panel TVs, including the following: Two sessions on large-screen liquid crystal (LC) TVs. Invited papers from Samsung Electronics, Hitachi, Sharp, AU Optronics and LG.Philips-LCD will describe how new technologies and advanced techniques have led to improved image quality. Two sessions on the sudden resurgence of FEDs. SED Inc., a joint venture between Canon Inc. and Toshiba Corp., will discuss the fabrication and characterization of its new 36-in. surface-conduction electron-emitter display (SED). Other topics will be Japan's National FED Project, the improved image quality of carbon-nanotube FEDs and applications for color FEDs for high-definition TV (HDTV). The emergence of rear-projection TV will be covered on May 27. Sessions will be held on liquid crystal-on-silicon (LCoS) and digital light processing (DLP) projection systems, thin rear projectors and new light-emitting diode (LED) light sources. Invited papers from Mitsubishi and InFocus Systems will describe the latest developments in ultrathin projectors. Texas Instruments will discuss an LED illumination technique that will enable very small DLP projectors, and Philips will describe a handheld mini-projector that uses LED light sources. Papers from Pioneer, Samsung, NHK and Matsushita will describe the image-quality improvements in plasma-display panels that have led to full digital HDTV. The University of St. Andrews, Philips Research Eindhoven and OSRAM Semiconductors will present papers on advances made in solution-processed-phosphorescent and polymer materials. A session on the production of OLEDs using scanning evaporation systems will include an invited paper from SK Display Corp. that describes the mass production of full-color active-matrix OLED (AMOLED) displays.
