A sad story of HP calculators

[Garth Wilson]

I read approximately 35 years ago that the heat-and-humidity combination is a real killer for LCDs. Here in Southern California where we live, it can get pretty hot for short times every year, but the humidity is not bad. The only ruined LCD I've seen was one that was stored in an attic for a long time. None of the LCDs in our family has gone bad (and that's a lot of LCDs).
