Photonics-based eReader


I just read that the AmazonKindle is getting competition ... in color:

[The new Qualcom eBook] borrows the same elements that allow a butterfly’s iridescent wings to shimmer, using tiny flexible membranes that react to electrical charges, overlaid onto a mirrored surface. Light reflected back out through those membranes is refracted so that interfering wavelengths create colors, and because the membranes used are bistable, once they have been set to display a certain color they require virtually no power to maintain it, only if it needs to be changed. The system also needs no color filters, no strong backlighting to be visible in direct sunlight and no polarizing lenses.
