quantum dot technology

1. CES 2015

2. What are quantum dots?
Simplifying things greatly (as this guide aims to do, mostly),
quantum dots are incredibly small particles. They range
between 2 to 10 nanometres in diameter, which is equivalent to
50 atoms. Yes, atoms. You can't measure these things using
your old school shatter proof ruler. It's this small size that gives
quantum dots the unique properties to improve our tech.
The colour light that a quantum dot emits is directly related to its
size; smaller dots appear blue, larger ones more red. In LCD
screens they're applied as a way of eliminating the need for
White LED backlights and colour filters. As Dr. Raymond M.
Soneira, President of DisplayMate, explains: "Instead of using
existing White LEDs (which have yellow phosphors) that
produce a broad light spectrum that makes it hard to efficiently
produce saturated colors, Quantum Dots directly convert the
light from Blue LEDs into highly saturated narrow band primary
colours for LCDs."

3. - Higher peak brightness
One of the reasons TV manufacturers like quantum dots is that th
ey allow them to produce TVs with much higher peak brightness.
This opens up some interesting possibilities, such as enabling su
pport for 'high dynamic range' TVs that support standards such as
Dolby Vision.
Imagine shots where looking into the sun actually feels like lookin
g in to the sun for real and you get an idea. To do this you need b
righter TVs and quantum dots deliver exactly that.

4. ANOTHER BIG BENEFIT OF QUANTUM DOTS IS
IMPROVED COLOUR ACCURACY. THE LIGHT
PRODUCED BY QUANTUM DOTS IS SO CLOSELY
TIED TO THEIR SIZE THAT THEY CAN BE TUNED
VERY PRECISELY TO EMIT THE EXACT KIND OF
LIGHT NEEDED. THIS MEANS PURER, CLEANER
WHITES AND MORE PRECISE COLOURS.

5. IMPROVED BATTERY LIFE IN MOBILE GADGETS

6.  One of the contradictions of modern tech is that
people say they want better battery life, but when it
comes to it they'll choose a slimmer, sleeker and
'sexier' phone over a chunky one with better battery
life. Phones haven't been getting slimmer and
lighter by accident. Companies make them that
way because that's what sells.
 You can fiddle with the settings as much as you
like, but it's the screen that sucks down the most
power. Which is why the potential power savings of
quantum dots, believed to be up to 20 per cent, are
so attractive.

7. WHERE ARE QD USED?

8. • Despite any disadvantages, the versatility and
flexibility of QDs have proven to be valuable
assets, capable of outweighing any negative
aspects. This great advantage alone makes them
excellent candidates for the production line and
particularly significant for future developments.
