LCD Screen + -40C Winter = Bad?

[nobb]

For those of you with LCD screens in their cars, I'm just wondering how your screens handled the cold during winter. When it gets down to -40C, my carpc screen is very dim and the backlight has a pinkish glow.

I read some engineering journals which did testing on a CCFL backlight and the lifespan was only 500hrs at 0C, whereas it would be 25k hrs at 20C.

Just wondering if anyone has killed any LCD screens by using it in the cold.

It won't kill it, but it's not great for it either, like your engineering journal says.

Liquid crystal is just that: a liquid. Once it gets cold, it starts to solidify. More energy has to be pumped to the screen as it's drawing power to keep itself in a liquid state when on.

In Canada, though, it's just a consequence of owning one. You will have to replace it more frequently if you run it in the deep cold.
