whether you love apple hate them or feel nothing at all they do a great job of
capturing the imagination of would-be tech buyers with sexy sounding branding
like liquid retina xdr one of the major
features that they're pushing with their new macbook pro lineup but what the heck
does liquid retina xdr mean is it just
more marketing fluff or is there more to it
let's start by quickly talking about what a retina display is you probably
first heard the term quite a while ago as apple's been using it since the days
of the iphone 4 and all it means is that the display has a pixel density that is
high enough that you can't make out individual pixels at a normal viewing
distance so really just about any display is a retina display if you're
sitting far enough away from it though of course pixel density is still
important if you're holding a phone close to your face or sitting ARM's
length away from your laptop apple then started using the term liquid
retina in 2018 with the release of the iphone 10r but the iphone 10r was
actually a lower priced model within the iphone 10 lineup so
liquid retina was just a cool way of saying that the phone had a relatively
bog standard liquid crystal or lcd screen similar to what you'd find in
completely average tvs or monitors so is
the new liquid retina xdr on the 2021
macbook pros and ipad pros just more marketing hype it turns out the answer
is not quite the xdr stands for extreme
dynamic range and after we get through the mandatory eye roll over the use of x
for extreme it turns out that apple has put some really interesting tech into
these new displays for deeper blacks and crisper colors meister task is an easy
to use intuitive visual collaboration tool for task and project management you
can get organized with a simple kanban style overview of all of your tasks and
users are able to collaborate and work together more effectively as all files
information and documents related to the task can be stored in one centralized
place you can add as many users to your projects as you need and naturally
interact with them using comments mentions and reactions so align your
team like never before with meister task using the link in the video description
probably the most important improvement apple brought to liquid retina xdr is
the array of mini leds that backlight the display
all lcd screens need a backlight to function but nicer displays tend to have
more and brighter leds for their backlights that allow finer control over
smaller areas of the screen this allows them to be made dimmer to deepen shadows
or to be made brighter to make bright details pop the liquid retina xdr
display in the ipad pro has more than 10 000 mini leds backlighting it organized
into nearly 2600 individual dimming zones and this is all fit into a
relatively small tablet screen meaning that apple had to custom engineer its
own manufacturing methods because packing so many tiny leds into a small
space is a pretty delicate operation but the result is a display that can for
supported content get to a thousand nits
across the screen and 1600 nits in
smaller areas that's a high number for any display but it's especially
impressive for a mobile device that has to run on battery and it's something
that might be a selling point for folks who want to watch HDR content on their
laptop or tablet assuming they have deep enough pockets but mini led as cool as
it is still isn't quite as good in terms
of contrast as an OLED display which has
individual pixels that produce their own light and rumors are flying that apple
may transition to OLED for some of its future ipad models like they've already
done on the iphone but considering that OLED is an expensive difficult to
produce technology that typically can't get as bright as melee led not to
mention the fact that oleds can suffer from burning if you leave ui elements on
the screen for long enough we might be seeing liquid retina xdr and its mini
leds on apple products for quite a while maybe they'll sell it to us with a less
gimmicky name down the road but i wouldn't really bet on it thanks for
