Electronic paper (e-paper) looks like conventional paper and the bright wash of color it generates uses the ambient light for rendition, just like conventional paint, so no backlight is needed. Which means that the vividness of the color is maintained, even in bright outdoor conditions. Philips' technology allows different colors of ink to be built into one layer with each color controlled separately. This means the layer can be transparent, the same color as any one of the inks or even a mixture of multiple colors. Moreover, the saturation of each individual color can be controlled accurately – so any shade can be produced. Recently, Philips successfully realized a simplified, yet advanced version of its e-paper technology: e-skin. Since it is less complicated and less expensive to realize, it enables new applications. And because e-skin makes use of the ambient light, it is an inherently energy-efficient system, making it particularly suitable for application in portable devices as well.
While portable devices might be the focus in the short-term, this sort of technology could also be used for larger equipment and even wallpaper in your home. In other words, it might not be long before we can change the color and the entire ambiance of a room with the push of a button. [Philips ! via Pocket-Lint]
