when researching screen types for a new TV or phone purchase or whatever
0:05
figuring out which selection hits the right price to Performance ratio for
0:09
one's needs can be enough to drive prospective buyers insane and apparently
0:14
some companies didn't think we'd gone mad enough so they've introduced a new
0:19
style which uses a little other things called Quantum dots to increase
0:23
performance over standard LCDs while undoubtedly increasing standard prices
0:27
as well now modern LCD screens are made up of blue LED backlights that have had
0:32
a layer of yellow phosphorus added to them which causes their emitted light to
0:36
turn from Blue to White this white light is then filtered through red green and
0:40
blue subpixels at varying intensities creating the end color of a pixel you
0:46
know whatever shade of magenta floats your boat set in an entire array of them
0:50
and while this design enabled us to create a wide range of colors at pretty
0:54
darn fast refresh rates the style of white backlighting that they deployed
0:59
made their color Recreation especially for Reds a little bit on the weaker side
1:03
and this is where the use of quantum dots in LCD screens comes in QD LCD
1:09
screens also start with a blue layer of backlighting but instead of using
1:13
phosphorus to turn the light white red and green fluorescent nanoc crystals are
1:18
used these nanoc crystals range from about 1 and a half to a little over four
1:24
nanometers in size and actually emit
1:27
light instead of just filtering it so when the light of the blue LED causes
1:31
the red and green dots to illuminate it creates a purer white than before this
1:37
purer light is able to more efficiently pass through the subpixel filters
1:41
allowing Engineers to create screens which require less operation and energy
1:45
to achieve increased Spectrum ranges or in other words colors are able to be
1:49
brighter and more vibrant all while the screen is using less juice but while
1:54
Quantum do LCD screens boast a wider range of colors compared to their
1:58
regular LED back lip predecessors that does not automatically make them the new
2:03
king of the Rainbow Castle quite a few people who have seen them in action
2:06
still testify to the superior image quality of OLED screens this would be
2:11
largely due to their ability to shut off individual pixels creating much darker
2:16
blacks and giving them this like massive contrast ratio there are also a lot of
2:21
people who are questioning the ability of the initial run quantum dot screens
2:26
to handle motion blur properly at higher
2:29
refresh rates leading many to wonder why this technology is even being
2:32
implemented in the first place the answer of course is money as if it was
2:37
ever anything else like I previously explained QD LCDs operate at lower
2:41
energy costs than their competitors making them highly attractive to anyone
2:45
who wishes to reduce power consumption and then the other big upside to them is
2:49
that the production costs of quantum LCD panels can reportedly range anywhere
2:54
from as low as half to a third of an
2:57
OLED screen making them extremely attractive to manufacturers as well as
3:02
budget-minded consumers because the simple fact of the matter is that well
3:06
there's going to be the tech Geeks out that they're like OMG they put the word
3:09
Quantum in it I need seven most consumers already have screens capable
3:14
of displaying content meant to be viewed at the standard of 60 HZ or below and
3:19
don't generally seem to be interested in forking out huge sums of money for oleds
3:23
in which they may see very minimal benefits and then if you cross-section
3:27
like those guys with the people who are interested in reducing energy costs
3:31
expanding battery life on mobile devices and potentially driving the purchasing
3:35
cost down of their next upgrade then you arrive at this group of people that
3:40
might find Quantum LCD technology very very appealing because while it's not
3:45
gunning for the top dog spot with OLED
3:49
as a stop Gap solution until prices fall on OLED or new technologies are
3:53
developed it seems pretty compelling speaking of things that are compelling
3:58
especially if you're a freelancer or small business owner fresh books it's a
4:02
cloud Accounting Service designed with you know people who want to spend their
4:07
time doing their work and not spend all their time doing a bunch of like
4:12
paperwork and nonsense and reconciliations in mind it makes
4:16
invoicing getting paid and tracking expenses easier they've got an online
4:21
tool that helps you get your accounting done quickly and I mean they've got all
4:24
kinds of cool stuff so like they make invoicing simple your clients can pay
4:28
you online which is really neat your expenses are automatically tracked as
4:32
you spend and all the little details about cash flow are in one place and you
4:35
can even do things like log hours so you just update your freshbooks time sheet
4:40
from your phone and then it goes Boop okay project hours that goes right into
4:44
an invoice you send that to the client and as I mentioned before you can go
4:47
ahead and they can pay it online so if you're Your Own Boss you should be using
4:52
stuff that makes you feel like a boss and freshbooks is an easy way of getting
4:55
all that stuff done online so you can do what you need to be doing which is is
4:59
the work that you need to be doing so head over to freshbooks.com tequ and

lonus would also be acceptable thanks for watching guys like this video if you
5:11
liked it dislike it if you thought it just plain sucked leave a comment under
5:15
the video if you're you know had a suggestion for a future fastest Possible
5:18
episode just like this one don't forget to check out our other channels Linus Tech tips and a Channel Super Fun where
5:23
we have lots of like super fun stuff going on I think that's pretty much it
