How do you use an LCD display to measure enantiomer optical rotation?

I read that one way to check how much a specific enantiomer rotates polarized light is to use an LCD display. Kind of vague in my memory and I'm curious about it. Does anyone know how this is actually done practically?

I haven't the foggiest. I just use a polarimeter, although it's got an LCD display.
