Low-temperature Polysilicon TFT LCDs
Evolving Towards Higher Picture Quality Picture and Lower Power
200K-dot Transmissive Color LCDs in 2.0, 2.5, 3.5-inch Sizes
ACX300AK, ACX301AK, ACX302AK
The ACX300 Series (the ACX300AK, ACX301AK, and ACX302AK) are
even more highly evolved low-temperature polysilicon TFT LCD
panels than the earlier models that have been used as small-sized moni-
tors that meet the needs for high picture quality in AV equipment such
as digital still cameras and digital video cameras. As such, these new
products can truly be called the next generation products.
These panels, which take full advantage of the latest low-temperature
polysilicon TFT process technology and polysilicon TFT circuit tech-
nology, can achieve reduced power consumption, higher definition, and
increased transmittance at the same time, and promise radically in-
creased competitiveness for products that incorporate them.

Industry’s Highest Resolution
Achieved by Taking Maximum
Advantage of the Low-
temperature Polysilicon TFT
By taking advantage of not only the
high-mobility transistor performance,
which is a feature of the low-tempera-
ture polysilicon TFT, but also high
aperture ratio pixel design, Sony
succeeded in increasing the horizontal
resolution by 20% over earlier Sony
models. The ACX300 Series products
take full advantage of Sony’s low-tem-
perature polysilicon TFT technology to
achieve the high transmittance of
current 100K to 120K-dot class prod-
ucts (increased by 15% over 2.5-inch
Sony products) despite being 200K-dot
high definition products. This improved
definition provides smooth, fine-
grained high-quality picture without
apparent dots.
VOICE
ST LCD Corporation has begun
LCD panel production now. More-
over, they will be producing a full
product line of panels from an
early date. Pictures that are faith-
fully reproduced down to the
finest detail by advanced low-
temperature polysilicon TFT tech-
nology will become standard in
small-sized LCD monitors from
now on. I strongly recommend that
you try these products.
Low-Power Technology
To respond to the trend towards lower
power in digital video cameras and other
AV equipment, the ACX300 Series
adopts a precise power control system
for each drive circuit block in the panel,
and also adopts a 12-V supply voltage.
This reduces the panel power consump-
tion by 60% over earlier models, and
achieves the low power consumption of
50 mW (typical) (60 mW for the
ACX302) when 12-V drive is used.
Since all timing signal inputs accept 3-V
level signals, the LCD system power
can be reduced in products that include
these panels. Furthermore, since the
drive system uses the Sony CXA3268R
low power highly integrated IC, which
integrates the precharge signal (Psig)
and other signals that were previously
generated as external devices, the num-
ber of external components in the LCD
system can be reduced.
Lineup Supports a Wide
Range of Applications
— From digital still cameras
to small TV sets —
All of the unique TFT process and high-
quality technology developed by Sony,
the industry leader in low-temperature
polysilicon TFT panel development, is
applied in the ACX300 Series small-
sized LCD panels. The product line in-
cludes three sizes: 2 inches (the
ACX301), 2.5 inches (the ACX300) and
3.5 inches (the ACX302), and thus in-
cludes a screen size optimal for almost
any product, from digital still cameras
to video cameras and small TV sets.
Furthermore, since all models have the
same system structure, it is extremely
easy to create a series of related appli-
cation products.
High-Quality Panels
Supplied from a New Factory
The ACX300 Series panels are manu-
factured by ST LCD Corporation, which
is a joint venture between Sony Corpo-
ration and TOYODA AUTOMATIC
LOOM WORKS, LTD. and is located
in Aichi prefecture. These products are
manufactured on a fully automatic line
equipped with the world’s largest and
highest performance clean room. Low-
temperature polysilicon TFTs are
formed on the world’s largest glass sub-
strates in this high-quality line. Even
more than before, Sony is the leading
source for high-quality panels.
