Earlier this week LG.Philips showed off the first color A4-sized e-paper:
This is a second breakthrough in e-paper for LG.Philips LCD, which introduced the world's first 14.1-inch black and white flexible e-paper display in May 2006, the company said.
The 14.1-inch flexible color e-paper uses electronic ink from E Ink 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, according to the LG.Philips.
Like the black and white flexible display, the color version uses a substrate that arranges TFT on metal foil rather than glass, allowing it to recover its original shape after being bent. This model includes a color filter (CF) coated onto the plastic substrate, allowing it to display color images.
The use of metal foil and plastic substrate rather than glass substrate makes the flexible color e-paper display bendable and durable while maintaining excellent display qualities.
