The Advent Of The Era Of HDTV

• Since 2000, to improve the image quality of
  TV broadcasting, the broadcasting started to
  transform the signal from conventional analog
  signal into digital signal,. This reform of
  signal technology has been developed as a
  global-wide project today

?In 2004 the United States has conducted such
technological changing. In 2006 FCC has
transformed the National television Broadcast
signals into HDTV digital signal, and will fully
stop to broadcast the analog signals in 2009.

• ?Taiwan will start to broadcast the digital HDTV
  in 2008.

?China officially launched conversion project
of digital television signal in 2006. In 2008
Beijing Olympic Games comprehensive TV will
broadcast signals with high-definition digital.
?At the same time many other countries are
also included in the itinerary of this reform
schedule, and as it a forcibly reform project.

The coming of Digital TV Generation
?With the continuously improvement of this
signal conversion, TV reception system will also
change following the comprehensive reform.
?Traditional CRT monitors have been
eliminated and gradually replaced by LCD monitor.
?The Size of TV increases from the original
small size (2030) to large size(gt50) and even
more than 70-inch

• ?The global demand of replacing digital TV is
  about 200 million
• every year. The United States accounted for about
  40 million, China
• accounted for about 30 million demands of the
  market. The next few
• years China will overtake the United States as
  the world's largest
• market demand

Comparison Of Digital TV Performance (?)
Existing digital TV technologies have PDP,
TFT, DLP, LCoS. Widescreen which is a American
professional magazine released the technical
evaluation report in every performance comparison
with CRT, PDP, TFT,DLP,LCoS. The report shows
that LCoS leads other technology, and were
classified as the best.

Comparison Of Digital TV Performance (?)
PDP Its size is limited to the range of 42-inch
to 80-inch. Technology is almost controlled by
Japan. The product lifetime is relative short.
For large-size, cost is high. LCD Its a
capital-mass industry. To set up a 50-inch
TFT-LCD production line, the capital investment
almost require RMB500 billions. At present,
the LCD market is dominated by Japan, South Korea
and Taiwan. It,s not easy to get into the
industry for a new comer. The investment recovery
takes quite long time. DLP The technology is
exclusively owned by TI. For large-size rear
projection TV application, the disadvantage of
single chip DLP technology are insufficient
brightness, bad color saturation, color-break
effect, difficult to upgrade resolution to
1080P and so on. Its suitable for data projector
but not suitable for rear projection TV. LCoS
This technology is combined with the IC design
and TFT-LCD technology. High-resolution,
high-contrast, high brightness, long device
lifetime are its characteristic. Its suitable
for large size rear projection TV application.

Why LCoS?
LCoS Liquid Crystal on Silicon Combination of
two major technologies IC manufacturing and
liquid crystal display technology
Meet the requirements of HDTV high-definition,
high-resolution .With the potential for low-cost.

What is LCoS?

• The full text of the LCoS is Liquid Crystal On
  Silicon.
• Its structure is shown as figure.

Comparison Of The Physical Properties
In the mainstream of the current
projection display market, comparing with LCD,
DLP and LCoS by their physical characteristic,
High transmittance and high resolution of LCoS is
much better than former two kinds of technologies.

Technology Of LCoS HDTV
 LCoS HDTV compare with other technologies, the
advantages are 1. Higher
resolution 2. Brighter
images 3. The screen size is not
restricted 4. Lower cost potential  
5. Product lifetime is relative long and
easy to maintenance 6. Low-power
consumption 7. Non-radiation
