Electronically controlled polarization of a glass

idaka

Hi there,

I wonder if anyone heard or read anything about glass where one can control its polarization electronically. Or such that you can switch polarization on and off. Tried to google but all it gives references to polarized glass. Maybe I am using wrong term for such thing?

Thanks in advance,
Ildar

Welcome to the PF.

Use the search term "liquid crystal", or you can just look it up on wikipedia. That's the technology used in liquid crystal displays (LCDs).
