Quantum Dots Get Commercial Debut in More Colorful Sony TVs
Sony is using nanoscale particles called quantum dots to significantly improve the color of some of its high-end Bravia televisions. It showed off the technology, which increases the range of colors that an LCD television can display by about 50 percent, at the Consumer Electronics Show in Las Vegas this week. This marks the first time that quantum dots—which for a long time have fascinated researchers because of their unusual electronic and optical properties—have been used in a mass-produced consumer electronics product.
Other quantum dot displays are in the works. For example, last year Nanosys announced it would have a quantum dot backlight product in a notebook in 2013, but it hasn’t disclosed the specific product (see “Quantum Dots Give Notebooks a New Glow”).
