    Pixel Density

    Pixel density is referred as number of pixels per second(PPI).
    - PPI is the measurement of screen resolution in various contexts like image scanners, computer displays.
    - The units are not in square inches. Units are measured as number of pixels per inch.
    - The apparent PPI of any monitor depends upon the resolution of the screen.
    - A monitor in 800 x 600 resolutions is different from a monitor with 1024 x 768 modes.
    - The dot pitch of display determines the density of pixel.

    Pixels per inch (PPI) or pixels per centimeter (PPCM) is a measurement of the pixel density (resolution) of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner.

      Pixel density is a calculation that returns the number of physical pixels per inch on a screen or display of a device. It's often referred to as Pixels Per Inch or PPI. Pixel density has become increasingly important as the resolution of screens has increased dramatically in the past several years.
