AU Optronics to Unveil its Latest Technology for Mobile Device Applications

October 12, 2006

    HSINCHU, Taiwan, Oct. 12 /Xinhua-PRNewswire/ -- AU
Optronics Corp. ("AUO" or the
"Company") (TAIEX: 2409; NYSE: AUO) today
announced its latest lightweight, power-saving, and
environmentally-friendly technologies for mobile device
applications.  These technologies include; ATR-MVA
(Advanced Transflective MVA) featuring Sunlight
Readability; APE (AUO Picture Enhancer), which can save up
to 45% in power consumption; Color Sequential, featuring
high resolution; and 1.3mm super slim mobile TFT-LCD
modules.

    These latest technologies will be unveiled at the FPD
International Exhibition 2006, from October 18 to October
20, in Yokohama Japan.

    "Due to the popularity of mobile
telecommunications, the role of image display has gained
increasing importance.  Additionally, with the rapid growth
market of telecommunication applications, the demand for
quality flat panels has increased even more.  Therefore, in
addition to the features of wide viewing angle and high
resolution, it is believed that lightweight and power
saving features are to become the key future prerequisites
for mobile device applications," Dr. CT Liu, Vice
President of AUO Technology Center said. "Aiming to
meet the needs of the future market, AUO has developed a
series of improved and innovated technologies solely for
small to medium sized applications. The accelerated product
development allows us to service our customers with on-hands
efficiency and enhanced added value."

    ATR-MVA (Advanced Transflective MVA) Technology
featuring high contrast ratio >500:1 and sunlight
readability

    AUO's ATR-MVA technology allows for reading under
sunlight conditions in addition to providing lower power
consumption.  With ATR-MVA technology, the wide viewing
angle increases to above 160 degrees as well as a 500:1
high contrast ratio.  Due to improvements in panel
transmittance, this technology provides low power
consumption benefits and solves the problem of gray level
inversion, which makes it a perfect solution for outdoor
usage applications such as mobile phones, DSCs, and DVCs. 

    AUO Picture Enhancer (APE) Technology on Mobile
Devices, allowing high contrast ratio of 14,000:1 and
saving up to 45% in power consumption 

    AUO will unveil APE technology in its 2.2" mobile
phone panels with a high contrast ratio of 14,000:1 and
power saving up to 45% on average.  The mobile phone panels
applied with APE technology are able to advance several
digital image processes, including ambient backlight, hue
refinement, and saturation enhancement.

    Color Sequential Technology with improvement in high
resolution

    Unlike conventional TFT-LCDs containing three
sub-pixels (red, green, and blue per pixel), Color
Sequential technology utilizes solely one dot in one pixel
without a color filter.  AUO will introduce Color
Sequential technology in its 2" mobile phone panel
with the features of high resolution (pixels) of 240 x 320
(QVGA) and high color saturation of 97% NTSC.  Its temporal
multiplexing of RGB LED in a backlight can achieve around
2.5 times improvement in light efficiency, reaching a high
brightness of 400 nits.        

    These advanced specifications can meet the demand for
the upcoming 3G mobile phone market, allowing people to
even clearly see movie subtitles on their mobile phones.

    1.3 mm Super Slim Mobile TFT-LCD Module

    In anticipation of the needs of mobility, AUO will
unveil its new self-developed 1.9" mobile phone panel
with a super slim 1.3mm module thickness.  This is the
thinnest mobile TFT-LCD in the industry.
