Hey all, I am curious if anyone here knows how well an LCD screen holds up in very cool weahter. We have a mobile lab with a PC in it and it can get pretty cold. Currently we are using CRT's, and they have survived for years. We are talking about zero degree start up kind of situations, gradually warming up as the lab warms. What are the chances for damaging the screen under these kinds of conditions. Any personal experiences? Thanks.

My iPod screen is very faint when it is below 40 (F).

Only specially-designed LCDs will function in temperature extremes. (Car stereos, for example, need special LCDs.)
Most likely, in those temperatures, the LCDs will just stay dark. And since LCDs don't really heat up (the backlight tubes in them create negligible amounts of heat), they will never reach operating temperature on their own.
It probably won't harm the LCDs to be stored in those conditions; they just won't function until they reach temperature.

P.S. Look at some LCDs specs and see what they say.

A long time ago when I had a Duo270c, I woke up to find the color filter layers in the screen had cracked. I figured that the laptop in the open position was much warmer near the base of the screen than at the top so the screen expanded unevenly and cracked. It was an extremely fine crack that was almost unnoticable at normal temperatures.

I'm pretty sure cold temperature does harm an LCD. A mobile phone should be kept warm while skiing, otherwise the liquid in the display can freeze and damage it forever.
this quote is from the Applestore: [LCD] Operating temperature: 50� to 95� F (10� to 35� C)

ha, sorry, nothing that exciting
I appreciate everyones input, but we decided to go with the cheaper heat producing space consuming CRT's stacked on a homemade rack. Looks like crap, but hey, it works.

I wish they'd make the iPod screen out of that same LCD as car stereos. I've been looking to buy one but if i can't use it in winter waiting for the bus that's no good. It's been around -30�C (-22�F) here for the last couple weeks.

I leave my IBM laptop in the car all the time in the winter with no ill effects. Now, it's not been too cold here - only about 10F or so, but it still has not suffered. About the only downside is that it is sluggish for about 10-15 mins until it warms up.
Not sure about the special LCD for cars, though. Most that I have seen get quite sluggish in the winter until they warm up. The only difference I saw in a quick google search was some of the auto/military uses have built in heaters, but the ones I've seen in cars are quite sluggish until warm.
