Thread: LCD's at high temperature

I'll check with an LCD manufacturer tomorrow, but I thought I would ask
as long as I'm sitting here now.
We are using an LCD that is rated up to 60 deg C operating temp.  As
it happens, our application is causing those displays to occasionally
get up to that temp, and they do act up a bit - the segments get darker,
which makes the display hard to read.  We can probably live with this
if the displays are not being damaged when this occurs.
So my question is:  are the LCD's always ok when they cool down, or does
this stress them so that they won't last as long?  The 'storage temp'
rating - 85 deg C - is not exceeded.  In fact, they don't seem to get
much above 60 so far.
Thanks for any help.
