Quantum dots make greens and reds pop on screens (left) compared with other types of displays (right). Credit: Credit: 3M High-tech specks called quantum dots could bring brighter, more vibrant color to mass market TVs, tablets, phones and other displays. Today, a scientist will describe a new technology called 3M quantum dot enhancement film (QDEF) that efficiently makes liquid crystal display (LCD) screens more richly colored. His talk will be one of nearly 12,000 presentations at the 248th National Meeting & Exposition of the American Chemical Society (ACS) taking place here through Thursday. “Green grass just pops out at you from these displays,” says Eric Nelson, Ph.D., who helped create the plastic films that hold the quantum dots in a screen. “We believe this is the most efficient way to get to a high-color display.” That’s because quantum dot, or “QD,” displays need less energy compared to other high-color options. QDs are superconducting crystals so small that 10,000 could fit across the width of a human hair. Read more at: Phys.org
