display rates, the display is less than 300 micrometers thin and is flexible like a heavy paper. “You can roll it up and take it with you,” says Mr. In-Jae Chung of LG Philips, who describes the new surface as being as easy to read as a piece of paper.

LG.Philips LCD Develops Highest Resolution Color,
Flexible A4-Size E-Paper Display
Company’s 14.3-inch Flexible Display to Debut at CES 2008
Seoul, Korea (January 3, 2008) – LG.Philips LCD [NYSE: LPL, KRX: 034220], a leading
innovator of thin-film transistor liquid crystal display (TFT-LCD) technology, announced today
that it will debut the world’s highest resolution 14.3-inch flexible color E-paper display at the
Consumer Electronics Show (CES) 2008.
The 14.3-inch E-paper display, which is equivalent in size to an A4 sheet of paper, represents
a significant improvement over its predecessors with a never before seen resolution of 1280 by
800 pixels, and the ability to display 16.7 million colors, making it perfect for use in high end
multimedia applications. These displays are extremely energy efficient, only using power when
the image changes. Additionally, the displays are extremely thin, at less than 300 micrometers.
LG.Philips LCD’s use of metal foil and plastic substrates, rather than glass substrate makes
the flexible color E-paper display bendable and durable, while maintaining superior display
qualities. Like its predecessors, this 14.3-inch display uses a substrate that arranges thin-film
transistors (TFT) on metal foil rather than glass, allowing it to recover its original shape after
being bent. Furthermore, it can also be viewed from a full 180 degrees, so that images always
appear crisp, even when the display is bent.
This new display uses LG.Philips LCD’s proprietary processing technology to minimize panel
deformation and prevent circuit structure change during high-temperature processes-focusing
on the designs of the color filter structure and TFT, as well as color filter lamination technology.
This allows the display to overcome processing difficulties inherent in the lack of heat
resistance in metal foil and plastic substrates.
“Our new 14.3-inch flexible color display is nearly the equivalent size of an A4 size paper, but
you can roll it up and take it with you,” said Mr. In-Jae Chung, LG.Philips LCD’s chief
technology officer and executive vice president. “The reflective foil substrate is as easy to read
as a printed sheet of paper and can be used in a number of applications like electronic
textbooks and smart ID cards, where picture quality is as important as durability and
portability.”
LG.Philips LCD will also unveil the highest resolution mono flexible E-paper which is similar in
size to a B5 size paper and it plans to launch this mono flexible E-paper in 2008.
According to a recent report from Displaybank, a Korea-based research firm specializing in the
display industry, the flexible display market is projected to grow into a USD 5.9 billion market
by 2010, rising to USD 12 billion by 2015.
