Default LCD tool displays and cold shop temperatures?

Are LCD's damaged by cold or freezing temperature? I have several shop tools and multimeters with that type of display. I used to store them in my attached garage which usually didn't freeze or move them indoors if freezing threatened. Now I have a shop a bit further away that will most likely freeze at times.

Generally -40 is the danger point. Your car has a LCD display and it survives in winter doesn't it.

Well that brings up a story from way back.

I bought one of those fancy digital watches when they first came out, you know the ones with an alarm, date, time, 24 or 12 hour, I think it even had different time zones.
Was out enjoying the winter snow and inner tubing with friends. S0meone asked what time it was so I looked and said 1:34. They said no way it was that early. Looked again and it was still 1:34.

Turns out the liquid in a LCD display can either freeze or get so thick the particles that move around to make up the display get stuck. After it warmed up, it worked fine. Not sure what ever happened to that watch.

I would not be as worried about the display being effected by the cold. The machines rusting from the change in temperature and condensation would bother me more.

Lucky today with the internet, I bet you could look up the specifications for the operating and storage temperatures of most of the equipment. That would make you feel better when it gets cold out.
