AFAIK, the estimated lifetime (on-time, I should say) of LCD displays
is between 5 and 10 years only. Another reason to take batteries out
of LCD equipped gear without an on/off switch when not in use (e.g.
quartz intervalometer, MD-2).
And yes, they hate heat (and finger pressure!) and it makes them die
even sooner...
