In printing, the pixel density is conventional as dpi (dots per inch), which means the number of dots on the surface is 1 inch diagonal. In the display field of the screen, the pixel density is denoted ppi (pixels per inch), which means the number of pixels contained in the screen is 1 inch diagonal. Here, we will only look at the screen's ppi pixel density.
Each pixel (pixel) is made up of 3 main colors red - blue - green and so arranged next to each other in columns and rows. The pixel density of ppi will be calculated on a surface that is 1 inch diagonal, which equates to 2.54 cm.
Basically, the more pixels that are crammed and arranged, the smooth and sharp the display is. Because of that, considering the same screen size, which device has a higher resolution will result in a higher pixel density resulting in a sharper and clearer display. Today, mobile manufacturers are constantly improving the resolution and now it is up to 2K, which means the pixel density has increased to a very high number, maybe more than 500 ppi, typically. : 515 ppi on Samsung Galaxy Note 4 , 534 ppi on LG G3 .
The pixel density is closely related and directly related to the resolution of a monitor.
For example, considering the screen with a resolution of 1440 x 2560 on the 5.7 inch size of the Samsung Galaxy Note 4 we will have 1440 columns of pixels and 2560 lines of pixels. The formula for calculating the pixel density is as follows:
Total pixels diagonal length of screen 5.7 inches = Square root of the sum of squares of columns and squares of rows.
Here we have:
Pixel density of some high-end phones:
Sony Xperia Z3 : 424 ppi, Lumia 930 : 441, Samsung Galaxy Alpha : 312 ppi, Nokia Lumia 1520 : 367 ppi.
Pixel density of some cheap phones such as: Asus Zenfone 5 : 294 ppi, Lumia 630 : 221 ppi, Samsung Galaxy Grand Prime: 220 ppi ...
The pixel density of iPhone 4S is 330 ppi, pixel density of iPhone 5S is 326 ppi, pixel density of iPhone 6 is 326 ppi and iPhone 6 Plus is 401 ppi (These quantities are called by Apple as screen Retina).
