In Bengaluru, these scientists are working on writing with light

Abstract

In a bid to save paper and reduce e-waste, scientists in Bengaluru and now working on a way which would enable one to write with light. Liquid crystals developed at the Raman Research Institute, founded by Nobel laureate CV Raman, are being used with the final aim of designing a display device that would record writing with light - and erase it just as easily. The device could be used many times over.
