What is ppi in screen and display
what is ppi in screen of mobile.
Pixel Density in any device decides the quality of screen. So, learn all about what
is ppi and what is pixel in camera.
If we talk about screen
quality of any device either it is mobile, television, computer or laptop then
we may have listened about the term pixel. While reading and finding out the
specifications of any mobile, computer and television it is mention about the
resolution of screen with certain value of pixels. For example, Full HD Display with 1920*1080p.
The use of p (pixel) are also found in computer and television screen. If we
talk about smart tv, 4K tv and 8k tv we can find a pixel used in it in its
specification. Like, 54” (inch) Display with 3840*2160p. It means it in 4k tv
we can find about 8Million Pixel.
Before reading all about what is ppi it is better to know
about what is pixel in details.

what is pixel
Pixel is a tiny or small
component used in any screen. Pixel are small elements found or used in screen
of any device. The use of pixel is found in smartphones screen, computer and
laptop screen, television screen and devices having capacity to show an real
object in screen. Pixel are small element having tiny rectangle shape. If we
notice the screen of television from near then we can find the picture are
somehow blur type with small rectangle (4 side equal) size having Red, Green
and Blue color. So, it is clear that pixel are tiny colorful components which
have capacity to change any color. The single pixel contains a three sub-pixel
having RGB color. RGB color stands for Red Green Blue color. Pixel is a tiny
component of screen which can be seen only from closer distance to screen by
our eyes. If we look the screen from closer distance then we can easily see the
pixel used in screen but if we go far from screen then you can’t see the pixels
used in screen.

what is ppi
PPI (Pixel Per Inch) is a
measure of pixel in screen. PPI is a ratio of number of pixels used in screen.
PPI is a measure of pixel density which determines the exact resolution of any
screen. Pixel per inch helps in determining the quality and resolution of the
screen of the device like television display, smartphone display and computer
or laptop screen. We can say that the combine form of ppi is called an image. Pixel
per inch is that which calculates the number of pixels used in 1 inch or per
inch in screen. PPI helps to find how many pixels a square image of 1
inch has.
what is ppi in screen
PPI is also called as Pixel
Density. Pixel density is defined as the total number of pixels used or located
in a particular area of any screen. Pixel of screen is also measured in terms
of PPCM. PPI in screen makes the calculation of the number of pixels used in
your device screen. You can find the ppi of your mobile, computer and
television screen by calculating it.
In simple way, PPI is the value or certain number of pixels
attached or used in the screen of any device. Pixel per inch can be obtained by
calculating total number of pixels used in display or screen divided by the
size of the screen. The increase in number of pixels in screen makes the
clarity of the objects and more details of objects.

what is ppi determines
Pixels are small elements
which determines the quality of an image or object shown in a screen. Increase
in the number of pixels in photo or even in screen increase the quality of
image or of screen too. If the pixels used in photo or in screen is less then
the object shown in the screen can’t be clear and smooth. In screen having less
pixels we can find a number of small dots which affects in the quality of the
screen. Use of less pixel in image makes the image blur and unclear to view in
zoom in or even in normal mode. So, increase in number of pixels in image,
videos and screen increases the quality and vice versa.

How to Calculate Pixels or How to find PPI
We can calculate and find
out the pixel per inch or pixel rate used in screen of our mobile, computer,
laptop, television, tablets etc. in an easy step. So, after finding what is
ppi and what is pixel now find how to calculate pixel per inch of
the screen.
Suppose, you have a
smartphone having 6” (inch) display size and resolution of 1920*1080p. So, the
question may be,
If the size of screen is 6 inch with resolution of 1920*1080. Find PPI
or Pixel density per inch?
Answer: If the size of
display is 6 inch then at first, we have to find out the total resolution of
the pixel used in screen. To find total pixel used in the screen is by
multiplying the breadth and height of the screen.
Height (h) = 1920p
Breadth (b) = 1080p
So, total = 1920p*1080p =
2073600p =2million pixel (2MP)
From above it is clear that
the total MP used in the screen is 2MP.
Similarly, if we split the
screen size into two equal triangle form then we can find by using the simple
mathematical formula.
(1080*1080)
+ (1920*1920) = (1166400 + 3686400) = √4852800 = 2202.9071
When
we divide 2202.9071 by 6 then we can find around 367.15 pixels per inch in your
smartphone screen.

Does PPI matter?
Although increase in the
number of pixels in screen or pixel per inch in screen increase the quality of
object shown in the screen it matters on the size of screen too. The use of
large number of pixels in small size of screen may not give a better result or
the exact performance quality. The normal pixel per inch or pixel density in 1
inch is around 350 to 450 is good to sense by eyes. The use of 8k resolution in
4.5 inch display will not be suitable because the ppi of 8k resolution
(7680*4320) in 4 inch display is about 1440 ppi.
Our human eye can’t identify the pixels more than 399 in 1
inch. So, the use of more than 399 pixel in 1 inch of the screen doesn’t makes
any difference in quality of the screen. If the size of screen is large then
there must use more resolution or pixels to meet an average pixel to human eye
for better image i.e. 399 ppi.

What is ppi 300 or what is 300 ppi?
300 ppi means the average
density of a pixel per inch in any display is 300. It means that 1inch display
of screen contains 300 pixels.
How many PPI is 4k?
The exact resolution of 4k
UHD (Ultra HD) is 3840*2160p. When we multiply this two then we get around
8Million Pixel. If the size of screen is 6inch then the ppi of 4k will be 480
pixels per inch.
