June 12, 2007

    HSINCHU, Taiwan, June 12 /Xinhua-PRNewswire-FirstCall/
-- AU Optronics Corp. ("AUO") (TAIEX: 2409; NYSE:
AUO) is scheduled to participate in the Display Taiwan 2007
exhibition in Taipei, Taiwan from June 13 to June 15,
introducing the company's latest products and technologies.
AUO will be showcasing Taiwan's first 65-inch Full HD 120 Hz
LCD TV display, as well as mobile device displays with the
world's highest contrast ratio of 2100:1 and the world's
slimmest border of 0.9mm.
    With the theme of "Technology Matters," on
the agenda for LCD TV display technology, High Dynamic
Contrast LED Systems and advanced AMVA technology with high
contrast ratio and wide viewing angle will be on display in
the dark hall section. For audio-video display technology,
the main limelight will be placed on the mobile device
display with the world's slimmest border, and portable
displays to which AUO has successfully implemented LCD TV
TFT-LCD technologies. In the one-stop shop section, AUO
will be showcasing a full range of products, from as small
as 2-inch to as large as 65-inch, including Taiwan's first
65" Full HD 120Hz LCD TV panel, Full HD Moni TV, ultra
light notebook panels with white LED, a 42-inch portrait
general display TFT-LCD, and mobile device VGA/QVGA screens
with ultra high resolution.

    LCD TV display technology strengthens the theater-like
visual effect 
    By means of a 37" Full HD panel, AUO will be
showcasing its High Dynamic Contrast LCD System with the
utilization of local-adjustable LED backlight. This
self-developed technology can enhance the contrast ratio up
to 10,000:1 and achieve power savings of up to 50%. AUO will
also be introducing advanced AMVA technology with features
of 92% NTSC and a contrast ratio of 3,000:1. In addition,
AUO will be debuting its 46-inch FHD LCD TV panel, which
equips with new-generation lighting technology and the
world's thinnest HCFL (Hot Cathode Fluorescent Lamp)
backlight, up to 50% thinner than previous designs reach
CCFL-like module thicknesses.

    Portable display technology enhances features of mobile
device displays
    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. AUO's 2.2-inch mobile
device display with the world's slimmest border of 0.9mm in
simply elegant design will be showcased to the public for
the very first time during Display Taiwan 2007. In
addition, a number of industry-leading technologies that
AUO has successfully implemented LCD TV TFT-LCD
technologies to small- and medium-sized displays will also
be on display, including AMVA-mobile technology,
ASPD-mobile technology, APE-mobile technology, and VGA
transflective technology.
