AUO to First Debut 'Smart Module' at 2010 Intersolar in Germany

The Only Manufacturer with Most "First" Achievements in the Vertical Supply Chain

HSINCHU, Taiwan, June 3, 2010 - AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) will
exhibit at 2010 Intersolar in Munich, Germany from June 9-11 to showcase a
series of innovative solar technologies. After the integration of vertical
supply chain in just over a year, AUO has achieved many industry-leading
technologies in solar upstream and downstream value chains. It is the only
manufacturer that can integrate all outstanding technologies at the same time
in the solar industry.

The products AUO will showcase at Intersolar include high-efficiency
EcoDuo mono-crystalline solar modules, EcoDuo PM220P00 multi-crystalline
solar modules, and first debut of "Smart Module". Intersolar, founded by
ESTIF (European Solar Thermal Industry Federation), BSW (German solar
industry association) and ISES (The International Solar Energy Society) in
1991, has become the largest solar technology and product trade show in
Europe, attracting many well-known global manufacturers to join every year.

AUO will debut the industry-leading "Smart Module" that can increase the
power generation at Intersolar this year. A particular layer of thin-film is
coated on the surface of the "Smart Module" which can reduce reflection to
increase ray transmission and the power generation of PV modules. Besides,
this thin-film has self-cleaning ability to dissolve foreign particles on the
PV module, so that the surface of the PV module keeps clean. Therefore, it
can reduce reflection to increase ray transmission when light is incident, as
well as have the obvious anti-reflection effects for incident light with
different angles. This effect not only can increase module power, but also
can reduce the frequency of manual cleaning and the long-term maintenance
cost. Specifically, the PV system using "Smart Module" during the initial
operation can increase power generation by about 3%; three months after
installation, the power generation can increase by about 4%.

AUO solar is the only "Total Solutions" provider, offering many
industry-leading technologies in the vertical supply chain. In terms of
polysilicon, AUO now collaborates with M. Setek to obtain high-quality
polysilicon and solar wafers on the upstream side to produce the solar cell
wafers with the highest efficiency. With the advanced wire saw slicing
technology, M. Setek has already established the mass production ability of
140 um ultra-thin wafers. Meanwhile, M. Setek's innovative technology to
recycle silicon has been approved for epitaxy, which takes leading place in
the world. AUO's upstream product processing can conform to a green promise
as well.

With the strategy of providing the total solutions, AUO will continually
cooperate closely with partners in the industrial value chain to rapidly
develop the solar market globally. AUO has entered into a joint venture
agreement with SunPower to invest in a solar cell manufacturing facility in
Malaysia. Through the collaboration in technology and intellectual property,
AUO aims to produce solar cells with the highest conversion efficiency rate
globally and offer the best services to our clients.

AUO's solar module plant in Brno is the first automated module plant in
Europe among Taiwanese companies. The equipment move-in was completed in
April, and the module plant plans to enter into mass production in June of
this year. The total capacity is expected to reach 100MW in 2011. The
production line is built with a highly integrated automation system, which
significantly increases product precision. The quality of the solar modules
is therefore assured, offering the best choice of products "designed by
Taiwan and made in Europe" for European customers.

In addition, AUO aggressively participates in larger projects and PV
investments, expecting to execute open-field PV system projects in Italy. It
is estimated the total power generation can reach 6.5 MWp. The project in
Verona in Northern Italy for the power generation of 752kWp will be finished
in June 2010. AUO will also tightly cooperate with local agents in each
country to jointly develop a whole sales network of PV modules. It is
expected that global sales offices will be established by the end of 2010,
offering great and timely energy services to global clients.
