when researching screen types for a new TV or phone purchase or whatever
figuring out which selection hits the right price to Performance ratio for
one's needs can be enough to drive prospective buyers insane and apparently
some companies didn't think we'd gone mad enough so they've introduced a new
style which uses a little other things called Quantum dots to increase
performance over standard LCDs while undoubtedly increasing standard prices
as well now modern LCD screens are made up of blue LED backlights that have had
a layer of yellow phosphorus added to them which causes their emitted light to
turn from Blue to White this white light is then filtered through red green and
blue subpixels at varying intensities creating the end color of a pixel you
know whatever shade of magenta floats your boat set in an entire array of them
and while this design enabled us to create a wide range of colors at pretty
darn fast refresh rates the style of white backlighting that they deployed
made their color Recreation especially for Reds a little bit on the weaker side
and this is where the use of quantum dots in LCD screens comes in QD LCD
screens also start with a blue layer of backlighting but instead of using
phosphorus to turn the light white red and green fluorescent nanoc crystals are
used these nanoc crystals range from about 1 and a half to a little over four
nanometers in size and actually emit
light instead of just filtering it so when the light of the blue LED causes
the red and green dots to illuminate it creates a purer white than before this
purer light is able to more efficiently pass through the subpixel filters
allowing Engineers to create screens which require less operation and energy
to achieve increased Spectrum ranges or in other words colors are able to be
brighter and more vibrant all while the screen is using less juice but while
Quantum do LCD screens boast a wider range of colors compared to their
regular LED back lip predecessors that does not automatically make them the new
king of the Rainbow Castle quite a few people who have seen them in action
still testify to the superior image quality of OLED screens this would be
largely due to their ability to shut off individual pixels creating much darker
blacks and giving them this like massive contrast ratio there are also a lot of
people who are questioning the ability of the initial run quantum dot screens
to handle motion blur properly at higher
refresh rates leading many to wonder why this technology is even being
implemented in the first place the answer of course is money as if it was
ever anything else like I previously explained QD LCDs operate at lower
energy costs than their competitors making them highly attractive to anyone
who wishes to reduce power consumption and then the other big upside to them is
that the production costs of quantum LCD panels can reportedly range anywhere
from as low as half to a third of an
OLED screen making them extremely attractive to manufacturers as well as
budget-minded consumers because the simple fact of the matter is that well
there's going to be the tech Geeks out that they're like OMG they put the word
Quantum in it I need seven most consumers already have screens capable
of displaying content meant to be viewed at the standard of 60 HZ or below and
don't generally seem to be interested in forking out huge sums of money for oleds
in which they may see very minimal benefits and then if you cross-section
like those guys with the people who are interested in reducing energy costs
expanding battery life on mobile devices and potentially driving the purchasing
cost down of their next upgrade then you arrive at this group of people that
might find Quantum LCD technology very very appealing because while it's not
gunning for the top dog spot with OLED
as a stop Gap solution until prices fall on OLED or new technologies are
developed it seems pretty compelling speaking of things that are compelling
especially if you're a freelancer or small business owner fresh books it's a
cloud Accounting Service designed with you know people who want to spend their
time doing their work and not spend all their time doing a bunch of like
paperwork and nonsense and reconciliations in mind it makes

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