LOS ANGELES, May 16, 2011 - Hanvon, a leading global eReader and touch technology manufacturer, today
unveiled the Hanvon ERT Touch Technology, a revolutionary new method of
enabling touch-based interfaces, at the Society for Information Display
(SID)'s 49th International Symposium, Seminar and Exhibition (Display Week
2011). The Hanvon Dual-Touch ERT Technology is a flexible, highly accurate,
lower-cost touch technology that outperforms comparable capacitive, resistive
and acoustic pulse recognition technologies in precision, data report rate
and ease of use. For the first time, Hanvon allows manufacturers to enable
both electromagnetic resonance technology (ERT) and touch technology on a
display. The new technology is currently commercially available to
manufacturers in the U.S. and globally.

"With the increasing adoption of mobile, eReader and tablet products,
touch screens have become the primary user interface," said Mr. Liu Yingjian,
president of Hanvon. "Consumers should be able to interact with their devices
quickly and accurately and manufacturers should be able to meet those demands
at a reasonable cost. Hanvon's Dual-Touch ERT Technology is the first finger
touch plus ERT in the market to deliver this experience to both consumers and

The Hanvon Dual-Touch ERT Technology combines the functionality of touch
with the accuracy and convenience of an electromagnetic resonance technology
(ERT) stylus, which shuts down "false" touches when in use. Hanvon brings the
two technologies together, while allowing dual-touch input. Hanvon's new
technology meets consumer demand for finger touch displays while also
lowering the cost to eReader manufacturers by adding a series of antenna
sensors to the sensor board.

Hanvon's Dual-Touch ERT Technology has a number of key benefits compared
to other alternatives:

    - Dual-touch interface - Touch displays integrating the technology will
      work with both ERT styli as well as traditional touch interfaces.
    - Increased precision - Using an ERT input pen, accuracy is as great as
    - Lower cost - Compared to capacitive touch, Hanvon's technology is 30-50
      percent less expensive;
    - Easier manufacturing - Hanvon's Dual-Touch ERT Technology works by
      adding an antenna network just above the sensor board. This can easily
      be added to any existing manufacturing process.

"The eReader market has had rapid growth in recent couple of years.
DisplaySearch forecast the worldwide eReader display market will reach 98
million units in 2018," said Dr. Jennifer Colegrove, vice president, Emerging
Display Technologies at DisplaySearch. "Touch screen technologies with high
transmissivity, capable of sensing both finger touch and pen writing and at
low cost, will be widely adopted on eReader devices and tablet PCs."

The Hanvon Dual-Touch ERT Technology uses less power than comparable
technologies but offers superior precision and a more natural handwriting
experience. It also offers a transmittance rate of 100% and a data report
rate of 200 dots per second. The typical thickness of the control is less
than 0.8mm and less than 2 mm for the board.

The technology will be on display and available for demonstration at
Display Week 2011 Booth #1455.
