This is an analysis of a phone screen, a laptop screen, and a TV screen.

Pixels are visible in three colours – red, blue and green – in all the screens, but the pixels of each screen differ in shape and size. There are variations in the pixel densities. Based on the pixel density, the approximate size of one pixel can be calculated.

Smartphone Touchscreen

Pixel density: 326 ppi

Pixel size: 78 μm

The individual pixels are not clear, but are seen as continuous bands of colour. The space between them is white.

Laptop Screen

Pixel density: 112 ppi

Pixel size: 227 μm

Pixels are much larger than those of a phone screen. They are distinct, and the space between them is black.

Bright blue screen

Yellow screen

Red screen (PowerPoint theme colour)

Dark green screen (Excel theme colour)

Blinking cursor on white screen

A cursor is six pixels wide!

TV Screen

Pixel density: 53 ppi

Pixel size: 479 μm

These pixels are the largest of all. They also have an arrowhead-like shape, compared to the rectangular pixels of the laptop and phone screens. They are spaced close together, in continuous bands.
