About PPI:
Pixels Per Inch (PPI) refers to the number of pixels per inch. The higher the PPI value, the higher the density at which the display can show images, and the higher the realism.
PPI is a unit of image resolution. The higher the PPI value, the richer the image details. The number of pixels per unit area varies by camera brand or production time. Common values are 72PPI, 180PPI, and 300PPI. For example, the A710 camera produces images at 180PPI by default.
DPI (Dots Per Inch) refers to output resolution, for output devices such as printers. Typical laser printers have an output resolution of 300DPI-600DPI, phototypesetters for printing can reach 1200DPI-2400DPI, and common photo printing is generally between 150DPI and 300DPI.

Screen PPI Calculator
PPI is based on the diagonal pixel count divided by the physical diagonal size in inches.
