LG. Philips LCD has announced that it has developed the world’s first 14.1-inch flexible color electronic paper display. Also called e-paper, it is equivalent in size to an A4 sheet of paper and can be rolled up as well.
The LG.Philips LCD 14.1-inch flexible color e-paper uses electronic ink from E Ink to produce a maximum of 4096 colors. It can be viewed from a full 180 degrees. Thus images when viewed on this 14.1-inch flexible color e-paper always appear to be crisp, even when the display is bent.
This happens to be the second breakthrough in 2-paper for LG.Philips LCD, which introduced the world’s first 14.1-inch black and white flexible e-paper display in May 2006.
Just like the black and white e-paper, the color version too uses a substrate that arranges TFT on metal foil rather than glass. This allows it to recover its original shape after being bent. This model includes a color filter (CF) that is coated into the plastic substrate, allowing it to display color images.
In fact, since metal foil and plastic have been incorporated into this 14.1-inch flexible color e-paper, its makes the display bendable and durable while maintaining excellent display qualities. This would not be possible had glass been used.
LG.Philips LCD developed a 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 CF structure and TFT, as well as CF lamination technology. According to the company, this allowed processing difficulties present in the lack of heat resistance in metal foil and plastic substrates to be overcome.
More importantly, these newly developed 14.1-inch flexible color displays are energy efficient and only use power when the image changes. Besides, the displays are really thin, measuring less than 300 micrometers. The images that are displayed on this color e-paper are comparable in quality to printed pages.
