Peacock feathers form basis for reflective displays, could bring color to e-readers soon
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.
Samsung entices with electrowetting displays at SID 2011: coming to consumers later this year?
Liquavista has teased us with the potential of its electrowetting displays for years, but we hadn't gotten to peep its panels post-acquisition until now, at SID 2011. In addition to the several screens we'd seen before, there was a new monochrome model that operates at low frequencies (down to sub-hertz levels) to cut down on current consumption. We also laid eyes on its chromatic displays, but in comparison to Mirasol's tech, electrowetting has a ways to go to match the image quality of IMOD. However, Sammy said that its reflective screens can be constructed with minimal mods to existing LCD manufacturing plants, while making Mirasol requires fresh fab facilities. Such a factory isn't exactly cheap, and Mirasol's large-scale production plant won't be around until 2012. So Samsung might snatch the market if it gets there first, and the rep we spoke with said the company hopes to have products shipping this year. While we wait for their hopes and dreams to come to fruition, view the vid after the break. %Gallery-123865%
Liquavista displays go out in the sun, look better than all right (video)
We've seen Liquavista displays plenty of times at various trade shows, but so far they've always been locked up indoors. Now they've gone outside to enjoy the weather, and ARMdevices.net was there to capture the results. The low-power color and monochrome screens are shown looking at least as good in the wild as they do in captivity, and when placed next to a traditional LCD (in the laptop on the right) the difference is clear. Granted, the colors are a bit washed out, but the refresh rate is certainly far higher than anything we've seen from E Ink. While there's still no firm word on how much this technology will cost manufacturers, converting from standard LCD production to Liquavista production is said to be relatively painless. How painless? We'll rather disappointingly have to wait for at least another year before we find out, as these aren't slated to go into production until the second half of 2011.
