Why are nits used to promote the brightness of phone screens over other units of measurement discussed this lecture?

Nits are used as the units of brightness for computer displays, so it would make sense to use it for cellphone displays. A nit is a candela / square meter, so we can relate it to the other units of luminous intensity.

A cd is 1 lm/sr and lux is measured in lm/m^2, This means that while nits(luminance) requires only the the light source, lux(illuminance) also requires an observer or distance. This site gives good background http://www.skytopia.com/project/articles/luxK.html

How is luminance calculated? Or is it just a certain value for specific types of light? I remember getting the infrared luminance question wrong on midterm 1. Why is the luminance of infrared light = 0?
