Sony to Sell Quantum Dot TVs
Tubes of quantum dots emit different colors of light. A Sony TV, set to go on sale this spring, will be the first commercial electronics product using quantum dots.

Some of Sony's new high-end TVs, set to go on sale this spring, will be powered by a nanotechnology called quantum dots. The quantum dots will allow LCD TVs to display about 50 percent more colors, MIT Technology Review reported.
Quantum dots are tiny, nano-size crystals of semiconductor materials that scientists have been studying for decades for TV displays and other applications. This will be the first time they'll show up in a mass-produced consumer electronics product, Technology Review reported.
Quantum dots absorb and re-emit light in different colors, depending on the dots' size, Nature News explained. The Sony technology, which was developed by Massachusetts-based QD Vision, creates red, green and blue light using red- and green-emitting quantum dots alongside pure blue LED lights.
Sony plans to sell TVs with quantum dot displays under the "Triluminos" name. If the Triluminos follow the example of other high-end TVs Sony plans to sell, they'll be very pricey.
Another company that seems close to selling a quantum-dot display is 3M. 3M has paired with Nanosys of California to make a quantum-dot LCD screen, but hasn't announced what products the screen might go in, Nature News reported.
