Although the number of attendees and exhibitors were down from last year, the Society for Information Display (SID; San Jose, CA: International Symposium, Seminar, and Exhibition (SID 2002), held recently in Boston, MA, dazzled everyone with an array of flat-panel displays of all sizes and technologies that featured vivid and sharp colors. According to Mark Goldfarb of Palisades Convention Management (New York, NY;, the firm that managed SID 2002, the overall attendance was approximately 6500 compared to 7500 in 2001. Last year's attendance set a record and was approximately 20% higher than that of 2000. This year's exhibitors numbered 260 compared to 280 in 2001, and exhibitor booths totaled 474 compared to 524 in 2001. However, a record number of technical papers—approximately 320—was presented.

The show received praise from most attendees and exhibitors. Exhibitors agreed on the noticeable reduction in show attendees, but also agreed that the quality and business interest of the attendees were considerably better than in other years. Show emphasis seemed to be focused mainly on chip, display, and color products and performances rather than on technologies.

In a keynote address entitled "Let's get real—Today's 'Sky is the limit' mentality inhibits the market," Peter Hopper, chief executive officer at Philips Mobile Display Systems (Hong Kong;, warned display manufacturers to downgrade the technology hype and get in tune with users' needs. To that end, he offered some recommendations to small-display vendors. The market has changed from the 50% growth of the 1990s to the 10% to 20% growth expected in 2002. Customers now need different kinds of support, and manufacturers need a real-world understanding to accommodate them. Vendors must know the market trends and translate them into display requirements. Overpromising the ultimate display can damage the market.

Ken Werner, editor of Information Display magazine (New York, NY;, the official publication of the SID, notes that the show was dominated by OLED (organic-light-emitting-diode) display-exhibiting companies, such as Dupont, Eastman Kodak, RiTdisplay Corp., Optrex, Sony, Cambridge Display Technology, Universal Display Corp., Philips Components, eMagin, Opsys, Neoview/Sunic System, and Toshiba-Matsushita Display. For OLED products, he commends the colors presented by Sony's 13-in., 800 X 600-pixel OLED display. Also, Toshiba-Matsushita Display showed a larger 17-in., 1280 X 768-pixel OLED. Focusing on small size, Eastman Kodak demonstrated its 2.16-in. full-color OLED display.

Vice president David E. Mentley of the market-research firm iSuppli/Stanford Resources (San Jose, CA; presented a talk "Display Market and Technology Trends." According to Mentley, the display-component business is expected to total approximately $50 billion for cathode-ray tubes (CRTs) and flat-panel displays (FPDs) in 2002. Now a mature and commodity market, CRT shipments are anticipated to remain fairly level at 250 million units shipped from 2002 to 2007. Total CRT sales during that period should rise slightly from $20 billion in 2002 to nearly $24 billion in 2007. Steady improvements in CRT technology, such as a flatter face, a finer dot pitch, a shorter neck, and a wider screen, are maintaining user interest. Prices lower than those for flat-panel displays are also contributing to the continuing success story of CRTs.

According to Mentley, active-matrix thin-film-transistor (TFT) liquid-crystal-display (LCD) technology is currently the dominant FPD technology. Sales are anticipated to reach approximately $23 billion in 2002, with worldwide TFT-LCD shipments of 575,000 units. The leading manufacturers are L.G. Philips with a 17% market share and AU Optronics with a 10% market share. Over the past 17 years, major manufacturer locations have shifted from Japan to Korea to Taiwan.

Mentley says OLED displays offer an attractive set of performance characteristics and provide a rich color picture. Their attributes include a low operating voltage of 5 to 20 V, a thin and lightweight structure, full color, wide viewing angle, and high contrast. The OLED display-market sales are projected to soar from less than $100 million in 2002 to $1.7 billion in 2007.

The display industry does have some shortcomings, though. Technology competition is intense. The several competing technologies have strong supporters and financial backing. In addition, the market is being driven by just a few high-value applications. Moreover, users are reluctant to change their technology choice.

In sum, Mentley says that FPDs are steadily replacing CRTs. Computer and television applications account for most of the flat-panel sales. The next growth wave is predicted to be in consumer and mobile products. However, price reductions are needed to sustain market growth, and new materials and technologies must be discovered to propel progress.

New products introducedOn the show floor, exhibitors unveiled a host of new products. Clare Micronix (Aliso Viejo, CA; showed the MXED301 gray-scale row-and-column driver/controller for monochrome passive-matrix OLED displays. This unit provides a 128-column current-sourcing anode driver and 80 common-cathode row drivers to support digital interfaces and OLED display panels.

Market visionAccording to the Semiconductor Industry Association (SIA; San Jose, CA;, worldwide sales of semiconductors increased to $11.07 billion in April 2002, a rise of 3.1% over March 2002 $10.73 billion. Compared with April 2001 sales of $13.74 billion, however, April 2002 sales were down 19.4%. The SIA predicts that semiconductor industry sales will total $143 billion in 2002, a gain of about 3.1% over 2001's tally. It also estimates that semiconductor sales will increase 23.2% in 2003 and 20.9% in 2004, with revenues of $177 billion and $213 billion, respectively.
