It's been 30 years since the discovery of the Quantum Dot, now Sony is bringing the technology to the living room. The new technology promises to expand the color gamut of Sony's 'Triluminous' TV sets as much as 50% when compared to current TV sets. The key to the technology: tiny crystals that can manipulate electrons at the quantum level so they emit light at a precise wavelength. How cool is that?

Discovered in 1981, quantum dots did not find applications until 2002. That was when the Quantum Dot Corporation of Hayward, California, began selling them to cell biologists, who prize them as fluorescent imaging labels for proteins and other biological molecules.
Conventional LCDs use a high-intensity blue LED backlight whose glow is converted by a phosphor coating to create a broadband, white light used to make the moving TV images. The new Triluminos televisions instead pair an uncoated blue LED with a thin glass tube filled with quantum dots. Two kinds of quantum dots in the tube absorb some of the blue light from the backlight and re-emit it as pure red and green light.

The new range of TVs will be the first consumer devices to make use of quantum dots: a previously lab-based semiconductor technology, which uses "tuned" nanocrystals so small—around 10 nanometres in diameter— that they exhibit quantum properties
