Structural color -- that's engineer speak for a reflective display that mimics iridescence. And tech of that very sort could be trickling down into future generations of e-readers, thanks to current research by the University of Michigan. Using the "refined hairline grooves" of a peacock as a template, a research team led by Professor Jay Guo has found success in creating a prototype of one such high-res display by crafting nanoscale metallic grooves on silver-plated glass. Using the CMY color model (cyan, magenta and yellow) as its basis, the team was able to produce blues with a groove measuring 170 x 40 nanometers, reds at 60 nanometers wide and yellows at a width of 90 nanometers -- all with reflected sunlight and unaffected by viewing angles. At the moment, only static images can be reproduced, but Guo and his crew hope to add moving images to the format soon. If and when this reflective display makes it to market, you can surely expect e-reader battery life to go even more of a distance.

Talk about flying under the radar. While everyone's focus on Qualcomm's results last week centered on the mobile chip business going gangbusters, the company quietly revealed during its fiscal results call that it's backing out of producing Mirasol displays itself. CEO Paul Jacobs instead wants the company licensing out the butterfly-inspired screens to interested companies and will limit its direct commercialization to "certain" devices. The company isn't explaining why beyond the plan more closely matching "addressable opportunities," although the absence of any widescale launches (and unconfirmed but repeated talk of low yields at The Digital Reader) suggests that factory output never quite reached critical mass. We're hoping that someone picks up the color e-reader torch before too long and delivers more than just the reference model derivatives we've seen to date.
