00:00:00.520 --> 00:00:06.680
did you know that part of your gaming monitor or big screen TV was actually

00:00:03.879 --> 00:00:11.000
grown in a vat it looks like a micro Brewery but this is actually a chemical

00:00:08.639 --> 00:00:14.960
reactor creating Quantum dots the tech that's not only responsible for raising

00:00:12.960 --> 00:00:20.039
the color accuracy bar in millions of displays but also the key technology

00:00:17.359 --> 00:00:24.840
behind Samsung's still unreleased QD OLED displays the new best display you

00:00:22.640 --> 00:00:29.599
can get today I'm going to show you how Quantum dots are made in America in this

00:00:27.039 --> 00:00:35.000
crazy facility what role they're playing and bring micro LED displays to Market

00:00:32.239 --> 00:00:41.480
and why ultimately Quantum dots themselves might make OLED and micr Leed

00:00:37.399 --> 00:00:43.960

00:01:10.600 --> 00:01:17.280
whether it's a monitor or an LCD TV you may be watching this video on a display

00:01:14.960 --> 00:01:21.119
with Quantum do enhancement film that's the term that nanosys the company

00:01:19.040 --> 00:01:25.200
responsible for every quantum dot product that's ever been brought to

00:01:22.320 --> 00:01:29.680
Market gives to this the polymer film containing red and green Quantum dots

00:01:27.640 --> 00:01:34.159
that's placed among the Myriad filmed fil filters and diffusers that

00:01:31.439 --> 00:01:39.000
manipulate light on its way to your eye but what about these Quantum dots is

00:01:36.880 --> 00:01:42.840
quantum exactly are they just super small actually it has to do with the

00:01:40.880 --> 00:01:46.960
principle by which they operate Quantum confinement each quantum dot is a

00:01:44.920 --> 00:01:50.799
molecule that will trap or confine energy for as long as it can before

00:01:48.799 --> 00:01:54.520
letting it Escape in the form of colored light the color of the light that's

00:01:52.439 --> 00:01:58.960
ejected by the quantum dot is precisely related to its size give the energy a

00:01:57.000 --> 00:02:04.360
lot of room to Tire itself out and it'll emit a low freeny light like

00:02:01.640 --> 00:02:09.039
red give it less Runway and it'll emit a higher energy green light mixing a

00:02:07.240 --> 00:02:13.200
solution of red and green Quantum dots along with a clear polymer creates these

00:02:11.120 --> 00:02:17.400
sheets which have made the HDR content we love far more stunning and color

00:02:15.239 --> 00:02:21.879
accurate they take the wide band of colors that comprise the white light of

00:02:19.080 --> 00:02:26.400
a typical LCD backlight and isolate just the true red and True Green Light

00:02:24.360 --> 00:02:29.680
discarding the adjacent unwanted colors like orange and lime and other colors

00:02:28.160 --> 00:02:33.920
that aren't even fruits what comes out from the other side of this film then is

00:02:31.760 --> 00:02:39.159
a new white light made with cleaner ingredients that the LCD can then

00:02:35.760 --> 00:02:41.800
pixelate with its RGB sub pixels it

00:02:39.159 --> 00:02:45.000
smells like hot oil in here the great thing about Quantum dots is that you can

00:02:43.280 --> 00:02:50.000
change their size and therefore the color they emit Super incrementally 1

00:02:47.680 --> 00:02:54.560
nanm steps and this is done simply by changing the temperature that they're

00:02:51.800 --> 00:02:59.680
cooking at for example the blue quantum dot crystal is only 100 atoms and in a

00:02:57.560 --> 00:03:03.959
barrel of blue quantum dot material that now nanosys ships to its customers folks

00:03:01.680 --> 00:03:08.599
like Samsung display and Boe every quantum dot in that 16gal Barrel has to

00:03:06.400 --> 00:03:12.200
be 100 atoms this seemingly impossible feat is accomplished through chemical

00:03:10.360 --> 00:03:16.280
selfassembly which is automated with this badass industrial equipment and

00:03:14.280 --> 00:03:20.920
this badass industrial software it's basically a chemical reaction where each

00:03:18.239 --> 00:03:24.840
atom is deposited into its Crystal site by another chemical which becomes the

00:03:22.920 --> 00:03:28.640
byproduct that's later discarded the chemical reaction is endothermic which

00:03:26.519 --> 00:03:33.200
means it requires energy so they just heat the reactor because the outside of

00:03:31.239 --> 00:03:38.680
this reactor is made with a material similar to the heat shields Nasa uses we

00:03:36.080 --> 00:03:42.920
can't see what's going on inside but we can see the wavelength emitted by the

00:03:40.920 --> 00:03:46.680
growing crystals because of an optical probe that's plunged inside the super

00:03:44.760 --> 00:03:51.680
hot liquid now this reactor is called Corey and this one right here is called

00:03:49.360 --> 00:03:56.239
Shelly and that speaks to the multi-step process the dots go through where in the

00:03:53.879 --> 00:04:01.000
first reactor the core of the quantum dot is created and then later a shell is

00:03:58.760 --> 00:04:05.079
grown around it this helps eliminate defects that exist on the core which is

00:04:03.000 --> 00:04:10.760
important because a defective quantum dot won't eject its energy creating

00:04:07.879 --> 00:04:14.879
excess heat that could degrade or yellow the enhancement film surrounding it next

00:04:13.040 --> 00:04:19.639
the quantum dots are purified and chemical byproducts are removed before

00:04:16.840 --> 00:04:23.680
the final step Li exchange the liquid lians that are cured by UV light to form

00:04:21.959 --> 00:04:27.840
a solid structure in a Quantum do enhancement film may require different

00:04:25.960 --> 00:04:33.600
properties than say the liggans used in Quantum do in that needs to shoot out of

00:04:30.000 --> 00:04:35.160
an inkjet printer head that's right ink

00:04:33.600 --> 00:04:39.919
the next gen quantum dot displays hitting the market in 2022 are not LCDs

00:04:37.680 --> 00:04:44.639
with enhancement film they OLED displays with Quantum dots printed directly onto

00:04:42.280 --> 00:04:49.880
the OLED emitters and here's why that's a really big deal current big screen

00:04:47.240 --> 00:04:54.919
oleds are technically W oleds and LG makes them all the emitters are red blue

00:04:52.160 --> 00:04:59.320
and green mixed together to create white the sub pixels use color filters to

00:04:56.919 --> 00:05:03.400
split that white light back out because the colors aren't very pure and the

00:05:01.160 --> 00:05:07.720
voltage required to drive the organic emitters to high brightness is damaging

00:05:05.919 --> 00:05:11.520
to them we're talking burin and short lifespan that's why there's a fourth

00:05:09.639 --> 00:05:16.360
clear subpixel that just shines white light through these nextg oleds though

00:05:13.880 --> 00:05:20.080
which Samsung calls QD oleds don't need a white pixel in order to get high

00:05:17.759 --> 00:05:24.680
brightness they use only blue emitters and they shine them through red and

00:05:22.360 --> 00:05:29.199
green Quantum do ink for a color conversion not filtering now we haven't

00:05:27.600 --> 00:05:33.680
seen a finished product yet get subscribed for when we do but these

00:05:31.160 --> 00:05:38.840
displays should be brighter longer lasting and have better viewing angles

00:05:36.120 --> 00:05:44.160
than anything we've seen so far super exciting stuff I just I can't wait but

00:05:41.680 --> 00:05:48.160
James you might say why would I buy a QD OLED when microed is right around the

00:05:46.120 --> 00:05:54.080
corner is nanosys putting its eggs in the wrong basket actually they're in

00:05:51.120 --> 00:05:57.759
every Basket in early 2021 nanis acquired glow a leader in the

00:05:55.800 --> 00:06:01.720
development of micro LEDs but I'll be honest at first I didn't understand how

00:05:59.240 --> 00:06:07.919
micro Le could benefit from Quantum dots since a micr Le display should already

00:06:04.479 --> 00:06:10.880
have tiny RG and B LEDs that it turns on

00:06:07.919 --> 00:06:15.880
and off at will and they do but have you ever wondered why the microled TVs that

00:06:13.080 --> 00:06:20.560
are available today are so huge it's because the pixels are so big and they

00:06:17.759 --> 00:06:26.000
have to be big because of the D and led the diode at the center of a pixel the

00:06:23.479 --> 00:06:29.759
diode can efficiently create say blue but at the edges of a pixel where the

00:06:27.880 --> 00:06:34.479
material has been snipped off in order to conform to the pixel shape the diode

00:06:32.800 --> 00:06:39.440
gets a lot less efficient and in some cases won't emit any light at all but it

00:06:37.000 --> 00:06:43.199
will produce heat reducing durability this isn't a big deal if the pixels are

00:06:40.960 --> 00:06:48.759
large since there's more juicy emitting area compared to the edge area but that

00:06:45.840 --> 00:06:53.080
ratio changes as the pixels get smaller red and green are particularly affected

00:06:50.759 --> 00:06:57.479
by this issue so if you're talking about a very small display like in a pair of

00:06:55.280 --> 00:07:01.280
glasses where you need it to be super battery efficient while also having

00:06:59.560 --> 00:07:05.720
having a really really bright display so you can see everything on a sunny day

00:07:03.039 --> 00:07:10.400
well the limits of mini LEDs can quickly make them nonviable put some Quantum do

00:07:08.520 --> 00:07:14.479
color converting ink on those diodes though and suddenly the problem is far

00:07:12.360 --> 00:07:19.080
more tractable as is the manufacturing and cost of big screen micro LED

00:07:24.280 --> 00:07:34.639
TVs oh my God how do you do this

00:07:31.479 --> 00:07:37.520
cool I got one

00:07:34.639 --> 00:07:41.599
yeah and finally there's the long game Quantum dots that are not charged by

00:07:39.360 --> 00:07:46.879
shining a light on them but instead are directly connected to the display's thin

00:07:43.560 --> 00:07:48.319
film transistors replacing LEDs and yeah

00:07:46.879 --> 00:07:53.159
I'm sure the performance would be awesome but the real disruption from

00:07:50.400 --> 00:07:58.000
these devices would be in the cost and the manufacturing right now virtually

00:07:56.000 --> 00:08:03.879
all commercially available oleds are created using evap atively deposited

00:08:00.599 --> 00:08:06.520
materials in a giant grossly expensive

00:08:03.879 --> 00:08:11.080
vacuum chamber the limitations of these Chambers is why TVs come in the sizes

00:08:08.960 --> 00:08:16.000
that they do it's why the motherg glass they're cut from is the size it is and

00:08:13.560 --> 00:08:20.960
it's why display manufacturing has been a state sponsored Enterprise up until

00:08:18.680 --> 00:08:26.360
this point first in Japan then Korea and now China but once a flagship display

00:08:24.039 --> 00:08:31.759
manufacturing plant can be made for 10% of the cost private Equity can build a

00:08:28.879 --> 00:08:36.440
Fab and oddly shaped display panels for say German cars can be produced in

00:08:34.200 --> 00:08:41.000
Germany Supply chains will be less susceptible to Major disruption like

00:08:38.320 --> 00:08:44.760
they are right now and there will be more competition in display

00:08:42.479 --> 00:08:49.320
manufacturing with more Innovation but for now the all the Innovation is

00:08:47.720 --> 00:08:52.880
happening here in California at the nanosys research and Manufacturing

00:08:51.160 --> 00:08:56.880
