UC Riverside discovery has applications in signage, posters,
writing tablets, billboards and anti-counterfeit technology
Chemists at the University of California, Riverside have
constructed liquid crystals with optical properties that can be instantly and
reversibly controlled by an external magnetic field. The research paves the way
for novel display applications relying on the instantaneous and contactless
nature of magnetic manipulation—such as signage, posters, writing tablets, and
billboards.
