E-ink displays may be easier on the eyes and less power-hungry than backlit LCDs used in most tablets and phones, but in the color department they’re still playing catch-up. However, this could change thanks to a new type of material developed at Chalmers University of Technology that is flexible, ultrathin and can produce the full color range of an LED-backlit LCD, but requires ten times less energy than a Kindle’s e-ink display.
Like a conventional e-reader screen, the material functions as a reflective display, so instead of being backlit like an LCD, the surface reflects the external light that hits it. Electrically conductive polymers covering the surface change how that light is absorbed and reflected, which allows it to recreate high resolution images and text. The end result is a material that’s less than one micron thick, flexible and extremely energy efficient.
“The ‘paper’ is similar to the Kindle tablet,” says Andreas Dahlin, lead author of the study. “It isn’t lit up like a standard display, but rather reflects the external light which illuminates it. Therefore it works very well where there is bright light, such as out in the sun, in contrast to standard LED displays that work best in darkness. At the same time it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.”
In Brief:
- MIT researchers using the Alcator C-Mod reactor have achieved a new nuclear fusion pressure record of more than 2 atmospheres of pressure.
- The Alcator C-Mod is set to retire after over 23 years of use but its nuclear fusion experiments have brought us closer to nearly unlimited clean energy.
The inventor of the impossible EmDrive, Roger Shawyer, received a new patent for the next generation of his controversial engine and the US Department of Defense and the UK Ministry of Defense are both interested in obtaining the technology.
If the EmDrive works, which is under some debate, it would allow a military satellite to get close to its target without being detected, it would also revolutionize space travel, Shawyer told the International Business Times.
“Yes, the UK MoD and the US DoD are interested in EmDrive. It would clearly be useful for any intelligence-gathering platform. It provides good maneuverability and stealth orbits to be maintained.”
“More than five years after the last Harry Potter film was released, Warner Bros. is preparing to delve back into the Wizarding World with Fantastic Beasts and Where to Find Them. And Disney will release its temperately anticipated Star Wars spinoff Rogue One this December in US cinemas.”
“That’s a troubling question for NASA, an agency whose most valuable piece of real estate—the $10.9 billion sandbar called Kennedy Space Center—is also its most threatened.”
“Drip irrigation came to California in the 1970s, letting farmers plant more fruits, vegetables, and nuts more closely together and in desert areas not naturally suited for agriculture.”
The bunker door will be opened because the igniter, also called nitrocellulose, burns very rapidly and is only explosive when confined, Brian Salvatore, chairman of the chemistry and physics department at Louisiana State University in Shreveport and a member of the Camp Minden citizens’ advisory committee, said last week.
A magazine holding 114,000 pounds of igniter is scheduled for burning Saturday. Another one holding 84,000 pounds of igniter and 40,000 pounds of M6 artillery propellant is to be burned Oct. 29.
