What the heck are quantum dots? And why are they in my TV? Scientifically, they’re a nanocrystal made of semiconductor materials – which means very little to me. What I can tell you is that they’re in various high-end 2015 TVs from Sony, Panasonic, Samsung and LG and the result is a much wider range of colours.

It sounds a little like marketing hype but the technology is real and it honestly does make a big difference. Consumer TVs are not the only real world application for this technology and in fact they were first discovered nearly 35 years ago. They have been used in transistors, diodes, solar cells and other imaging devices.

Like I said though, quantum dots in TVs are all about colour. Depending on their size, they emit a particular colour of light when hit with any colour of light. And this light is much more pure than can be achieved in a typical LCD panel. So rather than a white LED back light, TVs with this quantum dot technology feature a blue LED back light which then ‘powers’ the blue and red channels created with quantum dots.

Sony Triluminous Quantum Dot Technology
There’s a bit more to it than that, but if you can get your head around that much, that’s the bulk of it. It is more expensive as there are literally billions of these dots in a big screen TV so it is really restricted to the higher end of the TV ranges. Sony calls it Triluminous, Samsung calls it Nano Crystal technology and most others simply refer to it as Quantum Dot. OLED still gives better black levels and contrast but this is a big step forward to improving colour. So if you’re after fantastic image quality for a much more affordable price, Quantum Dots are where it’s at.
