Viewing angle of 180 degrees achieved by applying Samsung's
proprietary S-PVA technology.12.44 million thin-film transistors used to achieve full HD
image quality of 6.22 million pixels.
Samsung Electronics, the leading provider of TFT-LCD display
panels, announced that it has developed the world's largest 82-inch
TFT-LCD. This full HD image quality TFT-LCD panel was developed at the
company's new production complex in Tangjeong, Korea. The soon-to-be
operational 7th-generation production facility uses glass substrates
that measure 1.87m x 2.20m.
Samsung has made a series of breakthroughs in TFT-LCD technology
ahead of the competition over the years. The company developed the
first 40-inch model in August 2001, the first 46-inch panel in October
2002, the first 57-inch model in December 2003 and now the first
82-inch panel.
At its 7th-generation Line 7-1, Samsung can produce two 82-inch
panels from a single substrate. Previously, technological limitations
prevented the development of LCDs of this size and competitive
technologies, such as PDP (plasma display panel) and DLP (digital
light processing) technologies, were used to produce such large-sized
panels.
Samsung's latest large-screen TFT-LCD offers a variety of
features. The company applied its patented Super Patterned-ITO
Vertical Alignment (S-PVA) technology to achieve extra-wide viewing
angles. In addition, the product boasts a low-dispersion color filter
and ultra high aperture ratio, achieving a contrast ratio of at least
1200:1 and brightness of 600nit (cd/m(2)). Response times are at 8ms
or faster, providing clear moving picture images. A
high-color-saturation backlight raises color saturation to 92% to
produce a premium image quality.
Sang Soo Kim, Senior Vice President and Head of the LCD
Development Center, states, "Our 82-inch LCD panel proves Samsung
Electronics' technological leadership. It uses our proprietary S-PVA
technology, eliminating distortion from all angles and offers a
180-degree viewing angle. With this panel, we have achieved the
world's best performance in terms of contrast ratio, viewing angle and
color saturation."
Samsung is set to begin operations at the world's first
7th-generation TFT-LCD production line at Tangjeong, Korea. This
facility can be used to produce the company's full line-up of LCD
modules for TV: from 23-inch (24 per substrate), 26-inch (18 per
substrate) and 32-inch (12 per substrate) to 40-inch (8 per substrate)
and 46-inch (6 per substrate).
Samsung Electronics is at least one year ahead of the competition
in terms of using 7th-generation production technology to make modules
of 40 inches, 46 inches and 57 inches. It is therefore in a position
to take an early lead in the fast-growing market for large-screen,
wall-hanging TVs.
The development of the 82-inch TFT-LCD highlights the smooth
launch of Samsung's and Sony's joint venture in S-LCD. The
7th-generation line will begin mass production at the end of March.
Samsung Electronics will unveil its 82-inch TFT-LCD at CeBIT 2005,
which opens in Hannover, Germany on March 10.

Terminology
PVA Technology
Patterned-ITO Vertical Alignment is a proprietary Samsung
technology for achieving a wide viewing-angle. The liquid crystal
molecules are originally aligned at 90 degrees vertically to the
electrodes. The passage of an electric field deflects the liquid
crystal molecules off-vertical, producing the required image. Similar
to the multi-domain vertical alignment (VA), the liquid crystals are
controlled by separating unit pixels into four domains.
S-PVA Technology
Samsung's patented Super PVA is an upgraded PVA liquid crystal
cell technology. The cell architecture accommodates eight, rather than
the conventional four crystals, so that the liquid crystal molecules
can be controlled in eight different directions and angles. This
capability greatly enhances the side viewing-angle of the LCD screen.
Color Saturation
This is a measurement of color purity and is compared against the
NTSC (National Television Standard Committee) standard of 100.
Commercial CRT TVs and LCD TVs normally have a color saturation of
72%, but a higher level is needed to achieve high-definition image
quality.
