What is PPI in electronic devices?

PPI stands for Pixels per inch, it is a metric which defines the pixel density or the sharpness of a screen, now to understand that, we have to first understand what pixel is.

Any screen whether it is of a mobile, laptop, TV, desktop, is made up of many small components called pixels. In a screen, thousands or millions of pixels are arranged in a line,

A pixel is further made up of 3 subpixels which emit 3 primary colors – Red, Green, and Blue. Now with the help of these 3 colors, a pixel can show any color on the screen.


It is a measurement of the pixel density of any screen or display. It also defines the resolution of a screen.

A greater number of pixels in a screen means you can see more details, which results into better quality, but this also depends upon the size of the screen and from how far or near you are going to look at it.
