Screen Pixel Density and CSS Pixel Ratio

"Pixel" is smallest unit/element of any display.

The total number of pixels that fit into an inch is referred to as "Screen Density" or "Pixel Density" and it measured as "Pixels Per Inch".
Pixel Desnsity have limits to display Pixels Per Inch depends on different screen sizes. When number of pixels per inch increases than it's screen-size limit, the Display resolution will increase but actual device width/height in pixels remain same. Actual device pixels are known as Device Independent Pixels or CSS Pixel Ratio.

Samsung Galaxy S7 edge have ~ 534 pixel density and actual pixel density is about ~ 134 so it have 4 xxxhdpi display pixel density.

Screen Resolution and Viewport

The sum of pixels which are displaying on a device is called as "Screen Resolution". and sum of actual pixels of any device is reffered to as "Viewport".

Samsung Galaxy S7 edge have 5.5" physical screen size and its resolution is about 1440 x 2560 Pixels with approximately 534 PPI pixel density. Samsung Galaxy S7 edge has viewport size 360 x 640 Pixels and its pixel ratio is about 4.
