The full form of ‘LCD’ is Liquid Crystal Display and ‘AMOLED’ is Active Matrix Organic Light Emitting Diode. The two most popular types of phone screens in the latest smartphones are the IPS LCD display screen or Super AMOLED display screen. Best cell phone screen type: LCD or AMOLED The Samsung Galaxy S8 has a 5.8″ Quad HD+ Super AMOLED screen with a 2960×1440 pixel resolution and 570 PPi. The Apple iPhone 7 with Retina 5.5-inch HD display of 1920×1080-pixels has only 401 PPi. The Sony Xperia XZ is the only Ultra HD 4K screen cell phone available now. Right now the Sony Xperia XZ is the highest PPi pixel density mobile phone with a PPI of 806. Thus we can calculate the sides of a 4 inch phone display screen to be 2.63 and 3.945 inches. We can calculate the length of any side of a phone screen from the diagonal size of the phone screen and the pixel ratio between X and Y axis. The PPI of mobile cell phone screens is got by dividing the number of pixels along either the vertical or horizontal axis by the length in inches of that side. PPI is actually the Pixel Density of the display screen of the mobile cell phone. PPI stands for Pixels Per Inch and is a measure of or how tightly packed the pixels in a mobile cell phone are. Some of the higher end cell phone resolutions today are Full HD=1080×1920 pixels, Quad HD=1440×2560 pixels and 4K Ultra HD=2160×3840 pixels. This means that there is 720 pixels in the ‘X’ axis or horizontally and 1080 pixels in the ‘Y’ axis or vertically. Cell phone screen sizes in pixels are normally represented by two numbers, for example, in the image here, the Cell phone screen sizes in pixels is 720×1080. When the pixels are densely packed together, you get a much clearer picture. The word ‘Pixel’ is an abbreviation of ‘Picture Element’. Pixels are the smallest blocks which make up the screen. The phone in the image has a screen size of 4”, which when converted to centimeters equals 10.2cms. To convert inches into centimeters, the inch size is multiplied by 2.54, since 1 inch equals 2.54 centimeters. The screen size is measured in inches, but in countries which have the metric system of measurement, it will be given in centimeters. This is the diagonal measurement of cell phone screen as shown in the image here. For example, measure from bottom left corner of screen to top right corner of phone screen. To know how the size of cell phone screen, you must measure the phone screen size in inches between to diagonally opposite corners.

How to measure mobile screen size in inches How phone screen size is measured The pixel size measurement of mobile phones are the number of pixels on the phone screen in the X and Y direction, that is the number of pixels in the horizontal direction into the number of pixels in the vertical direction. Now this has changed, the size of a phablet now starts at 6 inches diagonally. Phones with over 5.5 inch screen were called a phablet – a cross between a phone and a tablet. Just 2 years ago the largest phone screen size was about 5.5 inches diagonally. The standard screen sizes of cell phones available today can be anywhere from 4 inches to 6 inches diagonally.
This diagonal screen size measurement of phone screens is given in inches. Cell Phone Basics explained How is cell phone screen size measured, cell phone screen sizes in pixelsĬell phone screen size is measured diagonally as shown in the image here.
