Hp, Asu Unveil Paper-Like, Flexible Display


Hewlett-Packard (HP) and Arizona State University's Flexible Design Center have developed a prototype, paper-like, unbreakable, flexible computer display made almost entirely of plastic using self-aligned imprint lithography (SAIL) technology. SAIL allows an image on the display to maintain its form despite the display being bent and flexed. The technology consumes less power and requires 90 percent less material by volume than current computer displays. The researchers say the technology is a milestone in the effort to create a mass market for high-resolution, flexible displays. The technology could be used to reduce the costs of manufacturing laptops, smart phones, and other electronic devices, or to create electronic paper and signage.

"In addition to providing a lower-cost process, SAIL technology represents a more sustainable, environmentally sensitive approach to producing electronic displays," says HP's Carl Taussig. The plastic material used in the display is flexible Teonex Polyethylene Naphthalate (PEN), which was developed by DuPont Teijin Films. The display also uses E Ink's Vizplex imaging film, which allows images to remain on the display without applying a voltage, significantly reducing power consumption when viewing text.
