Light Spectra for the Microsoft Surface Pro 4    

The Backlights for LCD displays are white LEDs, which are made by using a Blue LED together with a yellow phosphor to transform some of the light for the Red and Green primaries. The spectrum of an LCD display is just the spectrum of its white LED Backlight filtered through the individual Red, Green and Blue sub-pixel filters within the LCD panel, resulting in broad rolling spectra for LCDs.

The Figure shows the individual Red, Green, and Blue Primaries in addition to White, which is the sum of all three.
