LG.Philips LCD has developed the world?s first 14.1-inch flexible color E-paper display, equivalent in size to an A4 sheet of paper.
The 14.1-inch flexible color E-paper uses electronic ink from E-Ink
Corp. to produce a maximum of 4,096 colors. It can be viewed from a
full 180 degrees, so that images always appear crisp, even when the
display is bent.
Like the black and white flexible display, the color version 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. This model includes a color filter coated onto the
plastic substrate, allowing it to display color images.
LG.Philips LCD?s use of metal foil and plastic substrate rather
than glass substrate makes the flexible color E-paper display
bendable and durable while maintaining its display qualities.
To make this new display possible the company developed proprietary
processing technology that minimizes panel deformation and prevents
circuit structure change during high-temperature processes.
LG.Philips LCD focused on the designs of the color filter structure
and TFT, as well as color filter lamination technology. This
allowed them to overcome processing difficulties inherent in the
lack of heat resistance in metal foil and plastic substrates.
These displays are also energy efficient, only using power
when the image changes. Additionally the displays are extremely
thin, less than 300 micrometers. The images displayed are
comparable in quality to printed pages, according to the company.
In October 2005, LG.Philips LCD unveiled the world?s first 10.1-inch flexible E-paper display. The company followed it up with its 14.1-inch model in May 2006.
