But an LCD uses a fraction of the power of a CRT.
"fraction" ???
My 19" CRT monitor use 75W
A normal 19" LCD monitor about 40-50W.


Tha ratio is typically 3:1 for small (15") screens, approaching 2:1
for larger screens. 1/3 and 1/2 are both fractions. Look it up.

John

The fraction is larger for smaller devices (common in HUDs and MultiFunction displays in aircraft).
