4K resolution is a generic term for display devices or content having
horizontal resolution on the order of 4,000 pixels. Several 4K resolutions exist in the fields of digital television and digital
cinematography. In the movie projection
industry, Digital Cinema
Initiatives is the dominant 4K standard. And this is it 4K, there is not
to technically explain it but this is what is necessary to understand. 4K Is a
resolution and it is measured in PPI (Pixels Per Inch ) just like every other
resolution. 4K displays are somewhat around 4000*2000 but we already have
1920*1080 resolution then why is it called 4K? it must be somewhere around 4
But the closest thing around this
is UHD and
that is 3840*2160. The higher the pixel
density, the better the
display looks, sharper and cleaner it looks.
What is Ultra HDTV?
Ultra HD also known as “Ultra High Definition”
On October 17,
2012, The Consumer Electronics
Association (CEA) announced that the official
term “Ultra HD” would be used for any display
with a 16 x 9 ratio with at least
1 digital input cable carrying a minimum resolution of 3,840 x 2,160 square
pixels.
Ultra HDTV
Resolution
Currently there
are 2 forms of Ultra HD, 4K
and 8K, both have an aspect ratio of 16:9:
4K Ultra HD (2160p) has a resolution of 3840
*2160 (8.3
megapixels), which is roughly
equivalent to 4K cinema or 4 times the number
of
pixels in Full HD format (1080p).
8K Ultra HD (4320p) produces an astonishing
7,680 × 4,320
pixel resolution (33.2 megapixels), which is roughly
the equivalent of an IMAX film or 16 times the pixel resolution of
Full HD (1080p). Some believe that Ultra HD technology raises Ultra HDTV health concerns.
Well everything depends upon the
distance from which we are viewing the panel, if we are using a Smartphone we
require a lot of pixels so it becomes comfortable while browsing through the
web. Nowadays 1080p resolutions are common. Smartphone pretend to have a average
Pixel density of 300PPIand for a Laptop the average PPI is 160. But while
viewing a huge TV screen at your home we sit around 5-10 foot to watch which
require less pixel density but as we already told as the distance increases the
pixel density decreases. Its like a physics equation where one thing is inversely
proportional to the other . the average pixel density we see through our TV is
about 40 PPI. Though the TV has less pixel density we will not able to view the
pixels unless we go near to the TV to view as we all might have done while we
were children.
But in a 4k TV you are not going to
see any of the pixels while there is a much higer pixel density than the normal
1080p resolution. 4k TV has is expected to have a average of pixel density of
about 125ppi. Watching through a 4K TV will be a incredible experience but for
that you must have one. In 2013 the price of 4K TV was much costly than what a
common man can think of buying but now this year the international CES we
witness some of the affordable TV, smartTV’s.
Anyways this is a revoulutionary
step towards the future and if they continue to progress we might see 4K, 8K
smartphone and TV’s very soon.
We are leaving you a link below in
case you need to watch how a 4K video feels like have a look its incredible.
Anyways stay tuned for more updates
because it’s the international CES week we will be posting the latest tech news
everyday!
PEACE!
