LCDs get brighter with nano polarization recycler

Abstract:
LCDs (liquid crystal displays) provide a popular method for lighting screens on everything from computers and TVs to watches, clocks, cell phones and more. However, as scientists Sang Hoon Kim, Joo-Do Park and Ki-Dong Lee from Korea report, the light efficiency of LCDs is below 10%. Realizing there’s room for improvement, the team developed a way to brighten LCDs by recapturing much of the lost light using a technique called polarization recycling.
