Quantum dots may be screening on your mobile by 2020

Research into using quantum dots in LCDs has been ongoing and several breakthroughs at research laboratories have proven that they can provide much a much wider and more accurate colour spectrum than conventional backlit LCDs.  The size of the dot effects the colour, with larger dots fluoresce red, mid-sized dots green and the smallest blue, emulating the familiar spectrum of pixels at a lower energy cost and greater accuracy.  DigiTimes is reporting on the predictions of DisplaySearch which feel that quantum dots will be the next step forward for LCD technology and could represent up to a quarter of the smartphone display market by 2020. 

The technology to incorporate quantum dots into displays is currently available but there are several hurdles which need to be overcome before you can expect to see them in your next mobile device.  First and foremost is the price of manufacturing, as with any new process the first generations are quite expensive to manufacture, even if it is ways to molecularly seed a panel with a tailored particles to produce quantum dots succeeds in large quantities.  Current mass production relies mostly on heavy metals such as Cadmium which are strictly regulated when used in commercial products and would likely not be approved for use in the production of mobile phones in the amounts currently required.  It won't happen in the next few generations of phones but keep your eyes peeled for greatly enhanced LCD panels by the end of the decade.

"The firm said that the penetration of quantum dots in smartphone TFT LCDs will be 3% in 2015, growing to 26% in 2020. Penetration in tablets will also be relatively high, with nearly 2% penetration in 2015, growing to 15% in 2020. The quantum dot penetration in LCD TVs is expected to be lower, due to the large area of TV displays. DisplaySearch forecasts that less than 1% of LCD TV screens will use quantum dots in 2015, growing to 9% in 2020."

Not sure about you, but I'd prefer seeing more colours on wider and larger screens such as TV (40"-60"), Monitors (20"-40"), etc.

Then again, Smartphones are sold more often than TVs and Monitors. I think the growth is being looked at as mass production and could lower the cost for 4K Quantum TVs (push aside, Quatro!).

If I'm not mistaken Sony already has been using this tech for almost 2 years now?


I have a Sony 55W905A set with this. The high color saturation settings are useless, as long as no content is shot or calibrated to make use of it. Normal content is far too saturated in these settings. Colors are also no better than for instance my Eizo CG303W, which uses CCFL and an AU Optronics panel (I think).

...q-dot is supposed to achieve good results both at lower energy use and cost.

" Current mass production relies mostly on heavy metals such as Cadmium ..."

I worry that China is going to play a major role in the impact on supply, the environment, and ultimately on the price.

I took a look at which countries are producing Cadmium. China, of course, is #1 by a big margin, but interestingly, more responsible nations such as, Korea and Japan are #2 and #3 respectively. Canada is top 5 as well.
