FPD expo sees rapid growth in display market

Keywords:FPD? 4th FPD Expo Taiwan 2002? LCD? PDA? LCD TV receiver?

FPD industry has traditionally been dominated by LCDs, and in the foreseeable future LCDs will continue to dominate FPD, despite claims of competing technologies.

This view seemed to emerge from the 4th FPD Expo Taiwan 2002 held May 27 to 29 in Taipei, Taiwan. Almost 90 companies, mainly from Japan, United States and Taiwan, participated in the show.

"The amount of LCD panel production will increase at a CAGR of 20 percent till 2010," said Zenzo Tajima, product manager, Hitachi Ltd. "Current main applications are notebook PCs, mobile phones and PDA, LCD TV receivers is the next target."

Nitin Kulkarni, president, Corning Display Technologies Taiwan, estimated that between 2002 and 2006 display market would grow at a CAGR of 25 percent to 30 percent. "Display market has taken off very well. Taiwan is the hot spot," he said.

David Lee, senior engineer, Hannstar Display Corp., listed the issues that were being addressed by the industry to make LCD TV receivers more competitive with CRTs. These issues were: fast response of under 12ms; high current ratio of over 500:1; wide viewing angle ; high brightness of over 500cd; high-color gamut of over 80 percent; low cost; and large size productivity. He estimated the number of LCD TV receivers will grow from 315,000 units in 2002, Q2 end to 533,000 units in 2002, Q4 end, and further to 1,027,000 units in Q4, 2003.

Ching-Chih Chen, VP, Quanta Display Inc., discussed about the size and price trends of TFT-LCD. "For notebook PC, mainstream will remain 14.1-inch", though its share will be corroded by 15-inch products, and will fall from 61.3 percent in 2002 to 53.3 percent in 2005. For monitors, mainstream will be 15-inch, slightly falling from 72.3 percent in 2002 to 70.0 percent in 2005. In the consumer market, 17-inch and 18-inch screens should see some penetration."

The first quarter of this year showed slightly rising price trend for all sizes of TFT-LCD. Chen said that prices should stabilize in mid-2002.

OLED emerges

OLED is emerging a powerful factor in display technology. Can it "take over" the LCD market? Kimberly Allen, director of technology and strategic research, Stanford Resources, said that the "single most important factor for the 'takeover' is to develop factories to create high quality OLEDs at low cost." She pointed out that notwithstanding the hype surrounding OLED, "LCD was increasing rapidly, but OLED was not yet on the chart."

Jang Hyuk Kwon, senior researcher and project manager, Samsung, pointed out the critical issues facing the OLED technology today. "OLED lifetime improvement through material and light efficiency improvements, good color patterning technology with capability of handling above Generation 3 mother glass, and good LTPS and active-matrix driving technologies to achieve natural gray scale are the issues currently being addressed by the industry," said Kwon.

OLED market is expected to show a CAGR of 90 percent by volume, rising from 4 million units in 2002 to 186 million in 2008, and 65 percent by value, from $112 million to $2.3 billion. Active matrix OLEDs will account for 50 percent of units and 78 percent of value of OLED market in 2008.

Corning's Kulkarni said, "the trend in display devices is moving towards thinner and larger glasses, which give display makers huge economies of scale. Presently 67 percent of the glass used belongs to 3G and 4G. In 2006, 54 percent of the glass used will belong to 5G."

4G glass measures 680-by-880mm, while 5G glass measures 1100-by-1250mm.

"Corning is thinking of 7G glass at present," said Kulkarni, who also disclosed that Corning's Taiwan plant will begin shipment of 5G glass by this year end.

Corning demonstrated 0.4mm glass at the show. This glass is not yet available commercially.

AU Optronics Corp., a Taiwan-based manufacturer of TFT-LCD, launched a series of large-size FPD modules. The products include Taiwan's first 50-inch FPD, first 21.1-inch TFT-LCD for TV receivers, and first 20.1-inch TFT-LCD for desktop.

The show was organized by Semiconductor Equipment and Materials Int. (SEMI). It was a vertically integrated exposition featuring material suppliers, and component and equipment makers.
