six years ago we put out a video on micro LED or microled as I call it an
emerging display Tech that looked poised to overtake OLED there was even a report
that Apple invested around $3 billion into micr Leed with an aim of debuting
it in a new Apple watch and that made some sense as micr Leed displays offer
crucial advantages over the current state-of-the-art OLED they last much
longer they resist burnning and they can get much brighter all the while also
having self-lighting pixel and those Inky dark black levels
but here we are 6 years later and micr Leed displays are barely anywhere to be
seen what gives for starters micr Leed
is very difficult to manufacture not only do you have to place the sub pixels
onto the display one at a time and there's a lot of them but if one of
those sub pixels ends up being dead then you have to take it off and put a new
one in its place but it can be tough to do this without damaging nearby pixels
and once this happens enough you've suddenly got a dud of a product a
related issue is just how small the pixels need to be although in a strict
sense you can build a micr Le display with big pixels Samsung's Almost Famous
the wall actually had relatively large ones the problem is that the Wafers upon
which the LEDs are printed are extremely expensive and to make micr Leed cost
effective you need to be able to make multiple displays from a single wafer
meaning smaller pixels but making pixels
that small is also quite challenging as some pixels are more likely to come out
defective and shrinking them down also makes them much less efficient for
example a micr Leed sized blue LED is only about 40% efficient but even that
is nothing compared to Red which is notoriously inefficient we're talking
around 1% efficient sounds like a lot of
energy and a lot of heat so how in the world is the industry looking at fixing
this problem we'll tell you right after we think MSI msi's MPG mt201 Dr monitor
arm is a pro gaming move when it comes to cleaning up your desk setup it
supports flat or curv screens up to 35 in and 44 lb with a gas spring design
for easy adjustments you can move it any way you want for your perfect view
installation is a breeze with tool-free setup and quick release and it even
keeps your cables neat plus it adds flare to your setup with over 20 Dynamic
RGB LED modes check out the MSI MPG mt201 Dr monitor arm in the description
today it's actually possible to combine Quantum dots which emit specific colors
of light according to their size with micr Leeds to make them brighter
although this is tricky because the number of photons coming out of the LEDs
is often higher than Quantum dots can effectively handle is something that the
industry is looking for a way to do effectively however despite the fact
that micr Leed can get brighter than OLED OLED technology partly with the
help of quantum dots has evolved to the point where bright Ness isn't as much of
an issue as it used to be which is important for HDR in fact there are now
OLED TVs that can hit 3,000 nits of brightness which is plenty bright for
most applications so where exactly does that leave microled it it did look like
the initial advantage of micr Leed namely better efficiency and enhanced
brightness would make it good for something like a smartwatch which you'd
often be looking at in bright sunlight Apple thought the same obviously which
is why they invested billions into micr Leed production for the Apple watch but
they canceled these plans in early 2024 due to the difficulties we already
mentioned as well as the fact that higher-end watch displays are pretty
darn good in terms of brightness and battery life and guess what the current
Apple watch uses OLED nanosys a major
developer of microled Technology likewise sold off their micrb Fab to a
startup that isn't even going to be using it to make displays instead they're going to use microleds for
multi-terabit interconnects so basically using it for optical communication which
is pretty cool in its own right but a very far cry from the original vision of
microed being the future of TVs monitors and watch displays between OLED's
development future looking bright and the emergence of competing Technologies
like qel or qdel essentially Quantum
dots that emit their own light when you feed them electricity that promise many
of the benefits of microed without the ridiculous manufacturing problems
microed might end up only being a thing in applications that we now consider
Niche for example they might end up powering augmented reality glasses due
to their High brightness we're talking like 3 million nits brightness it's
crazy but it's far from a sure thing in the meantime we do at least have this
cool micr Leed concept laptop but I'm not sure why you want everyone being
able to see what you're looking at from the other side of the screen so thanks for watching guys if you like this video
you might want to see our original video on microed you can check that out right
here so it's somewhere
