Epson electronic paper

Seiko Epson is making strides in its continued development of electronic paper, having unveiled a 13.4-inch (A4-size) prototype at SID 2008 on Wednesday, its biggest to date. The new e-paper nearly doubles the size and resolution of the company's last effort, unveiled last November, at 3104x4128 resolution, with 385ppi density. The company believes its latest represents the final stage in its efforts to replace traditional papers with electronic equivalents.

This latest prototype uses a combination of electrophoretic electronic ink developed by E Ink Corp and a glass substrate low-temperature polycrystal Si-TFT from Seiko Epson. Together, the technology results in a 10:1 contrast ratio along with 40% reflectance.

The company will now undergo market research to bring the technology one step closer to commercial use. [via Fareastgizmos]
