TimmyHNew E-Paper Technology Speeds Up

Research shows that photonic crystals can change color as quickly as other technologies.
Researchers at the University of Toronto, in Ontario, have increased the speed of their new color-changing material tenfold. The material, which uses photonic crystals, reflects bright, intense light of any color from red to blue, switching color based on the voltage applied to it. The technology could enable brighter, flexible color displays for electronic readers and billboards.
"To get color changes that go across from UV all the way to near infrared--it's the only material on the planet that can do it," says chemistry professor Geoffrey Ozin, who led the new work. "All I'm doing here is with one material tuning the voltage."
