    -- The world's slimmest border: 0.9mm
    -- The world's highest contrast ratio: 2100:1


    HSINCHU, Taiwan, June 7 /Xinhua-PRNewswire-FirstCall/
-- AU Optronics Corp. ("AUO") (TAIEX: 2409; NYSE:
AUO) today unveiled two breakthrough technologies for mobile
device applications: a 2.2" transflective panel with
the world's slimmest border of 0.9mm(1) and a 2.7"
panel with the world's highest contrast ratio of 2100:1(2).
 These latest technologies, along with other small- and
medium-sized TFT-LCD technologies, will be showcased at
Display Taiwan 2007, from June 13 to June 15, in Taipei.

    In terms of mobile devices applications, due to the
increasing needs of high contrast ratio and wide viewing
angle, the border width for small-sized panel is becoming
increasingly important. AUO's 2.2" mobile device
TFT-LCD possesses the world's slimmest border of 0.9mm on
both the right and left sides.  This is a half size smaller
than current products on the market today. In addition, the
upper side border width can be reduced to merely 1.2mm.
With this much slimmer border design, AUO's 2.2"
mobile device TFT-LCD can increase the active area and
enhance the image sleekness; yet still maintain the same
high quality resolution and excellent display quality
performance. 

    In addition, as multimedia playing functions in
portable electronic devices are becoming more and more
popular, high contrast ratio and wide viewing angle are
becoming essential features for small-sized displays. By
using novel domains-forming technology along with specific
pixel structure design, AUO's AMVA-mobile technology is
able to maintain stable liquid crystal molecular
directions, prevent press mura, and provide higher
transmittance. Also, by utilizing leading Multi-domain
Vertical Alignment design, the AMVA-mobile technology
effectively restrains dark state light leakage and
increases the aperture ratio, resulting in a higher
contrast ratio of up to 2100:1.  Also, AUO AMVA-mobile
technology has been successfully applied on 2.7"
mobile QVGA resolution mobile displays to fulfill the needs
of video calls and movie-playing.

    "The arrival of the 3G era accelerates mobile
handsets to become lighter, thinner, brighter, more elegant
and more interactive human-interfaced. To enhance contrast
ratio and improve motion blur is also crucial for mobile
devices displays," said Dr. CT Liu, AUO Vice President
& GM of Consumer Product Display Operations.  Thus, AUO
has successfully implemented large-sized TFT-LCD
technologies to small- and medium-sized displays, including
AMVA-mobile technology, ASPD-mobile technology and
APE-mobile technology.

    AUO AMVA-mobile technology provides features of high
contrast ratio and wide viewing angle, hence being able to
offer clear image quality on GPS. ASPD-mobile technology
can improve response time to 4ms gray-to-gray for the
enjoyment of playing handheld video games. APE-mobile
technology can enhance the image contrast and reduce system
power up to 50% and maintain image luminance. Dr. Liu
further stated that in the future, these mobile
device-exclusive technologies will be the competitive niche
for AUO in the consumer electronics and mobile phone
markets.
