Samsung e-paper display
Earlier this week in Korea, Samsung demonstrated a working e-paper display, or more accurately, a color active matrix electrophoretic display (EPD) and the world's first to use carbon nanotubes. At 14.3 inches, it is among the largest e-paper displays in existence. Developed in conjunction with Unidym, which created the carbon nanotubes for the prototype, the display is energy-efficient and doesn't require backlighting while remaining highly visible under direct sunlight. As with other e-paper displays, images are retained on the screen without requiring energy to constantly refresh it.

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.

New LG.Philips A4 e-paper
The joint company LG.Philips LCD says it has developed a new type of e-paper display, one which is claimed to be the best in its class. Although built in the standard A4 paper size, measuring 14.3 inches diagonally -- a format LG.Philips has already explored -- the new display is unusual in that it has a maximum resolution of 1280x800, slightly above the 720p HD ratio. It also has an abnormally high range of colors, extending to 16.7 million versus the frequently low-color or monochrome displays of e-book readers such as the Amazon Kindle.
