Plasma, LCD, LED, OLED… confused yet? There was a time when all TVs shared the same technology, but today it appears that there is a new technology every time you turn your set on.
Well, get ready for Quantum Dot! Quantum Dot was the talk of this year’s CES show in Las Vegas, and admittedly its prevalence took a few punters by surprise.
But is Quantum Dot really a breakthrough, or is it, as many have suggested, simply a stop-gap until manufacturers can get the price down, and the reliability up, of what is being touted as the next big thing – OLED?
Quantum Dot involves the use of a sheet of nano-crystals which vary in size from 2 to 10 nanometres – each nano-crystal emits a different colour depending on its size. The sheet of these crystals is placed in front of the LCD backlight, with the result that “colour reproduction rate and overall brightness are significantly improved”.
It is way too early for us to comment on the effectiveness of this technology. It is also far too early to predict if it will even survive (although LG has already announced a 4K screen using Quantum Dot). What we do know, however, is that this is going to throw another twist into an already confused marketplace.
