LG Philips high resolution paper display

CES report

Posted by: Ilse Jurrien

LG Philips LCD, a leading innovator of thin-film transistor liquid crystal display (TFT-LCD) technology, announced 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.

Paper display

High resolution paper display - Thin film transistor
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.

Paper display - Lamination technology
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.
